Visual Influence of LED Viewing Angle on Brightness Uniformity

Analysis on the Characteristics of LED Display Screen and LCD Splicing Screen

According to the questionnaire survey conducted by LED display manufacturers, many consumers do not know what is led display? What is LCD splicing screen? These questions often hinder customers' purchase.1. The luminous brightness is strong. When the sun shines directly on the screen surface within the visual distance, the display content is clearly visible2. Automatic brightness adjustment has the function of automatic brightness adjustment, which can obtain the best playback effect in different brightness environments3. Video, animation, charts, text, pictures and other information display, online display and remote control4. Advanced digital video processing technology, distributed scanning, modular design / constant current static drive, automatic brightness adjustment5. Super gray level control has 1024-4096 gray level control. The display color is more than 16.7M, with clear and realistic color and strong three-dimensional sense6. Static scanning technology adopts static latch scanning mode and high-power drive to fully ensure luminous brightness7. Imported large-scale integrated circuits are fully adopted, which greatly improves the reliability and is convenient for debugging and maintenance8. Static scanning technology adopts static latch scanning mode and high-power drive to fully ensure luminous brightness9. The image shall be clear without jitter and ghosting, and distortion shall be eliminated10. Super bright solid color pixel11. All weather work fully adapts to various harsh outdoor environments, with strong overall performance of waterproof, moisture-proof, anti-corrosion, lightning protection and earthquake resistance, good display performance and high cost performance. The pixel barrel can adopt p10mm, P16mm and other specifications.1. High brightness and high contrast: did LCD splicing screen has higher brightness, which is different from ordinary TV and PC LCD? The brightness of TV or PC LCD is generally only 250 300cd / m2, while the brightness of did LCD can reach more than 700cd / m2. Did LCD splicing screen has a contrast of 1200:1, or even 10000:1, which is more than twice that of traditional PC or TV LCD screen and three times that of general rear projection.2. Thanks to the color calibration technology professionally developed for did products, this technology can not only calibrate the color of still pictures, but also calibrate the color of dynamic pictures. Only in this way can we ensure the accuracy and stability of picture output. In terms of color saturation, didlcd can achieve high color saturation of 80% - 92%, while the color saturation of ordinary CRT is only about 50%.3. The brightness is uniform, and the image is stable and does not flicker. Because every point of LCD keeps that color and brightness after receiving the signal, unlike CRT, which needs to constantly refresh pixel points. Therefore, the LCD has uniform brightness, high image quality and absolutely no flicker.4. 120Hz frequency doubling refresh frequency, 120Hz frequency doubling LCD technology of did products? Can it effectively solve the tailing and blur in the process of rapid image motion? Enhance image clarity and contrast? Make the picture clearer? People's eyes are not easy to get tired after watching for a long time.5. Wider viewing angle, using this technology? The visual angle can reach double 180 (transverse and longitudinal). Through the application of PVA technology, namely "image vertical adjustment technology", the LCD splicing screen has a wider visual angle.6. Pure flat panel display. LCD is the representative of flat panel display equipment. It is a real flat panel display with no curvature and large screen? No distortion.7. Ultra thin narrow edge design, LCD splicing screen not only has the characteristics of large display area, but also has the advantages of ultra light and thin. It can be spliced and installed conveniently. The special LCD screen for splicing, with its excellent narrow edge design, makes the edge of its single chip even less than 1 cm, so that the small edge effect will not affect the overall display effect of the whole display screen.8. High service life. The service life of the backlight of didlcd LCD screen can reach more than 50000-100000 hours? This ensures the consistency of brightness, contrast and chroma of each LCD used for splicing display after long-term use? And ensure that the service life of the display screen is not less than 50000 hours.9. The reliability is better. The ordinary LCD screen is designed for TV and PC display, and does not support continuous use day and night. ID LCD is designed for monitoring center and display center? Support continuous use in 7x24 hours.

Design of LED Display Screen Based on GSM Module

Review: Google Glass Could Be Peek at Tech Future

SAN FRANCISCO - Google believes it has the perfect accessory for the next phase of technology, the mind-boggling and appearance-shifting category already being described as "wearable computing." The widely anticipated evolution hatched Google Glass, a spectaclelike device that contains a hidden computer, a thumbnail-size transparent display screen above the right eye and other digital wizardry. This Internet-connected headgear is set up to let users receive search results, read email, scan maps for directions and engage in video chats without reaching for a smartphone. Google Glass' grasp of voice commands even makes it possible to shoot hands-free photos and videos. I got a glimpse of what it's like to wear Glass recently and saw just enough to conclude that it could fashionable, especially as society works out the rules of etiquette for using the device. Although I doubt the device will become as commonplace as the smartphone, I don't think Glass is destined to be remembered as a geeky curiosity that never lived up to its hype. is touting Glass as a liberating breakthrough that will make technology more convenient and less obnoxious in social situations than checking a smartphone to see what's happening in your digital realm. Critics deride Glass as another disturbing example of a how enslaved people are to their devices and a sign that technology is obliterating personal privacy. Only about 10,000 people in the U.S. have been given the chance to pay $1,500 to own a test version of Glass as part of Google's "Explorer" program. So I've been eager to get a firsthand look at what all the fuss is about. I finally got a chance when Google invited a few technology reporters and bloggers to test Glass under the company's supervision at a specially equipped San Francisco office that Google calls a "base camp." Unfortunately, none of the Glass models we were allowed to sample were fully loaded with all the applications, or "Glassware," that have been designed for the device. It would have been nice to check them all out. Instead, CNN was the only app available for this test. I also couldn't log into my Gmail to see what that's like on Glass. Glass has the potential to be much more than a novelty, especially if Google lowers the price below $500 by the time the company begins selling the device to the general public next year. (The exact date has yet to be determined.) Google has strived to give Glass a sense of style by decorating the titanium frames in five colors: charcoal, tangerine, shale, cotton and sky blue. Glass also weighs about the same as a pair of regular sunglasses. Glass doesn't actually have any spectacles in the frame, though Google eventually hopes to offer that option for those who wear prescription lenses. I thought Glass looked best with a sunglass clip-on designed for wearing the device outdoors. Turning on Glass is done by tapping a finger on the right side of the frame. The device also can be activated by tilting your head upward. Glass users have to turn on the device frequently - because it automatically turned off every 30 seconds or so when I wasn't using it. This is meant to save the limited battery life (it only lasts about 90 minutes if you're recording a lot of video, but Google says the battery should be adequate for a full day's use for most people). Navigating the Glass software requires swiping a finger in a forward or backward direction or an upward or downward direction on the right side of the frame. Glass can connect to the Internet through a Wi-Fi network or by pairing with your smartphone through a connection. Once online, it's easy to ask Google's search engine for a piece of information. I wondered how the fared in a game earlier that day and Glass promptly delivered the score on a card displayed on the display screen while I carried on a conversation. An automated voice also announced the answer through a bone conduction speaker near my right ear. When I asked Glass for directions to another location in San Francisco, it pulled up a map on the display screen and adjusted my course as I walked in different directions in the room. The map was quite immersive because even though the Glass screen is small, the display is in high-definition and gives the illusion that you are seeing the image on something much larger. Google likens it to watching a high-definition TV with a 25-inch screen from 8 feet away. I didn't have enough time with the device to test that comparison, but there's no doubt the picture on Glass display is crisp. People who are severely nearsighted probably won't be able to see what's on the screen any more clearly than everything else in front of them. The screen is deliberately aligned slightly above the right eye so it won't prevent users from maintaining eye contact during face-to-face conversations. That means you need to glance up to look at something on the screen. Glass' coolest feature is its ability to almost instantly take photos with the device's 5-megapixel camera or record high-definition (720p) videos that provide a startling perspective on how your own eyes see things. This is done simply by saying "OK Glass, take a picture" or "OK Glass, record a video" and the device does it. The images then can be seen on the display screen. With the right app, they can be shared on Twitter or Facebook and stored on your Google Plus profile. I found myself wishing Glass had been around when my daughter was a little girl so I could have had pictures and video of so many precious moments that remain in my mind's eye. Many of those moments aren't around in photographic form because they were too fleeting to capture on a hand-held camera or camcorder. It's easy to see why the built-in camera on Glass is raising privacy concerns - even though smartphones already make it easy for people to take a photo or record video at almost any time in just about any situation. Google says Glass isn't that much different. The company has tried to minimize the chances of surreptitious photos or video being taken by ensuring a red light is visible whenever an image is being recorded. Nevertheless, Glass already has been banned from gambling casinos, movie theaters and some bars to protect against cheating, copyright infringement and privacy intrusions. I can see how a lot of people aren't going to notice when they're on Glass' candid camera. For instance, I recorded a video of a Google representative discussing the privacy worries about Glass without him noticing. I did it by acting like I was adjusting Glass on my head, allowing me to press on a small button on the top of Glass' right frame (this technique is an alternative to using the spoken word to command the device).

Could This Audi Change the Way We Drive?

New Audi TT coupe debuts completely 'hands on' infotainmentMalaga, Spain -Audi has just launched the third-generation of its sporty 22 coupe, the TT. Like its predecessors, it's one of the smallest cars to use an aluminium in its construction, with large parts of the frame, and the entire outer bodyshell all made of the lightweight metal.While the first TT has become a celebrated example of car design, the new model is also quite a leap forward, but in a very different way: the inside. The driver-centred cockpit (literally, since the whole dash curves towards you behind the wheel) has a radical new operating concept, what Audi terms its 'virtual cockpit'. You'll notice there is no longer a central display screen for infotainment functions - instead, everything has been condensed into the 12.3-inch, 1,440 x 540 pixel active display that replaces the driver's instruments. The graphics are ultra-slick thanks to the tablet-like resolution of the screen, and they should be: the system is powered by an Nvidia Tegra 3 processor which renders the key animations (eg tachometer) at 60 fps. Audi has reduced the number of contextual buttons down to two (from four) and while there's still a central rotary controller which supports touch and text input, the biggest change is that you can control all the functions of the system directly from the steering-wheel jog dial.Other features include contextual search, expanded voice commands and app-connected capability so you can eventually stream media from your smartphone's storage or app-based music services. It's a huge shift in man-machine interface, arguably one of the biggest made since BMW introduced iDrive 13 years ago. If all that sounds confusing, it's simpler in real life, being quite intuitive and easy to use when driving, and you could get by without reading a manual. We more or less did - watch this short video to get a better idea.Check out our overall verdict on the new Audi TT here , driven at its international debut in Spain, on CarBuyer.com.sg.

Best Fish Finders Are Better Than Casting Usually with Noise

Patience or tolerance is a fisherman's most grounded virtue. You can move without any destination for casting and wait. Whatever your technique, persistence now and again goes unrewarded. Once in a while the fish appear to be completely sustained, modest, or they essentially aren't coming since they are not around to be found. All the consideration you put into the best bait or making that ideal angling bait slips ineffectively into the water. In any case, it doesn't demand to be that way. The magnificence of a fish finder is that your technique is enhanced and your time spent all the more adequately. Not employed in accomplishing something to working with a fish discoverer or fish finder? Reluctant about the cost? Here's all that you have to think about fish finder. Fish finders are a useful apparatus regardless of what sort of angling you do- sea water or fresh water. The act of determining the best fish finders is best educated by what sort of angling you do.Some Important Tips for Buying the Best Fish FinderFixed or Portable Fish finders are attached for all time on different bigger angling boats. A compact or portable fish finder has different advantages. They allow adaptability, so you can appreciate a wide range of fishing-where the fish may go in advance of you. You don't need to pick between kayak fishing and lake angling. Ideal for rental vessels. They are simple, but difficult to transport and lighter weight. Furthermore, you can move the fish finder to areas. Or on the other hand, simply move the fish finder around the watercraft or boat.Fixed fish finders additionally have preferences. They are usually innovative, increasing your fish hunting amusement and expanding your setting. Your GPS maps might be progressively reliable, which is incredible if you are docked some place you cast a line from frequently. The screen width or size can be bigger. If you treat a boat, you are genuinely prepared your vessel for the best angling with a high-quality, excellent fish finder.Screen Size Purchase the fish finder with the greatest screen you can manage. Screens extend from 3.5"-16". You can see a greater amount of the data assembled by your fish finder at one time. For a decent mid-size screen measure, pick a 9" screen. Ensure that you don't penalty more essential highlights or features for perceptibility.Regarding for kayaks, which are little and low to the water, fish finders are in any case essential for checking areas and successful angling. You will need to pick a small screen than regularly suggested. Lightweight and waterproof are additionally vital features. If your heart is determined to a particular fish finder, include a waterproof case. Glare Protection Bright daylight can make the fish finder screen hard to examine. A few adjustments for this are basically to move the fish finder to a shaded spot or get a shadow visor. There is likewise LCD big screen that cuts glare when connected, yet you can likewise diminish the screen's splendor and complexity. More up to date fish finders have glare-safe screens. Summer sun can sparkle on. Particularly if you have an unfolding or open vessel or boat, this is an astounding feature.Low-light Fishing If you are having in the wintery weather or climate at day or night angler, search for a fish finder with an illuminated screen which provided with artificial light. GPS Combination GPS and fish discovering identification combos are most usual in quality or excellence fish finders. You might need to go less expensive and simply utilize a fish finder. We recommend spending somewhat more for a GPS, particularly if you are into watercraft or boat or kayak angling. For dock angling or shoreline angling, GPS might be less significant.A fish finder (or sounder) is a compelling gadget used to recognize the area of fish underwater. It additionally measures the overall profundity or the depth of the water. The instrument utilizes sonar innovation, where an electronic drive is changed over into sound waves. At the point when the wave hits a fish or any underwater highlights, it is thought about back and showed the fish finders showcase or display screen. The best fish finders will allow you to distinguish high potential angling territories, just as make routes and maps of your most preferred spots with GPS efficacy.

Basics; You Can Never Be too Thin (or Cheap)

UNTIL recently flat-panel liquid crystal display monitors played the same role that credenzas once did in corporate offices: they were given only to senior managers as a sign of their status.But L.C.D. monitors are making their way down the technology hierarchy. Several manufacturers are offering flat-panel displays intended for household users at roughly $400, the same price that a conventional cathode-ray tube display fetched just a couple of years ago.The most obvious advantage to flat-panel monitors is space. Most of the lower-cost liquid crystal displays I tested were about as thick as a hardcover book, and nearly all perched on a stand the size of a dessert plate. They consumed far less desk space than the C.R.T. screen I had been using.Once turned on, they revealed that svelteness was not their only distinguishing feature. All were much brighter than any C.R.T. display or laptop L.C.D. I had ever used. Indeed, unless I made adjustments, some were almost painfully bright. Representatives of various L.C.D. screen makers whom I consulted acknowledged that the brightness of some units were set too high to boost their showroom appeal. (All of them suggested that this trick was only played by their competitors, however.)Once properly adjusted, the added brightness was welcome, particularly in rooms where a flood of sunlight made C.R.T. displays look washed out. None of the liquid crystal display panels withered when sunlight poured in.The brightness and crisp colors result from a different screen technology. C.R.T.'s are essentially dark screens that create an image by generating light. In contrast, liquid crystal displays form images by blocking light. Every pixel contains a red, green and blue filter covered by a liquid crystal shutter that can open to allow light from the display's fluorescent backlights to pass through to users' eyes.For that reason, staring at aliquid crystal display screen for hours seems to be less stressful than working with a C.R.T. -- so much less so that for many people it justifies the higher price. Because the phosphors in traditional monitors dim rapidly, their images have to be refreshed 60 or 75 times a second, depending on the screen and the computer. In flat-panel displays, the liquid crystals rearrange themselves only when the image changes, and even then, the rebuilding is much less obvious.''For me it's difficult to go back to a C.R.T. just because of the stability of the image,'' said Rey Roque, vice president for marketing in the digital information technology division of Samsung, which makes both types of screens.Most computer owners have to go through some extra fiddling to set up an L.C.D. screen. While old-style monitors need an analog wave or signal from the computer to do their job, liquid crystal displays are digital, like the computers to which they are attached. That means that most L.C.D. models on the market have special signal-processing chips that go through the convoluted routine of taking the computer's analog signal (itself originally converted from digital data) and transforming it back into digital data.That is where the trouble begins. If the screen's analog-to-digital processor and the computer's graphics processor are not synchronized, the fuzzy images might send you running to the eye doctor. The Sony SDM-M51D and the NEC MultiSync LCD1550V start their adjustment programs automatically. The Sony, in fact, doesn't even indicate what it's up to while it sorts out the image. The Sharp LL-T1501A's automatic setting, however, could only advance things from extremely blurred to slightly blurred. It took some fiddling with manual controls to negotiate a settlement between the computer and the screen's electronics.Eventually this synchronizing ritual will disappear as more computers begin offering digital monitor output. This is already the case with recent Macintosh computers so the Apple monitor has the smoothest setup of all.There were few disappointments among the screens I tried when it came to image quality. The monitors that offered the best value were 15-inch NEC units that were also the least expensive: the MultiSync LCD1530V, which sells for $399, and the MultiSync LCD1550V, which was introduced this week and sells at the same price. The 1550V is slimmer and a bit more stylish so customers may want look for it in stores unless the older model is heavily discounted.In principle, Apple's 15-inch all-digital Studio Display ($599) should offer sharper image quality because it avoids unnecessary computer processing. While it was indeed crisp, it was not obviously superior to the best of the screens that have to transform an analog signal. With its shiny, translucent design, the Apple monitor looks like it just escaped from the Clinique counter at Saks. It breaks with the industry pattern by setting up like an easel, with two edges of its screen and a hinged arm providing three-point support. Unfortunately, that arrangement requires more desktop space than the single pods of other screens, and the shiny plastic surrounding the screen creates annoying reflections.The Sony SDM-M51D ($580) was the biggest disappointment despite its attractive exterior design. The unit I borrowed had an annoying defective pixel that remained constantly lighted. It also came packed with a notice warning that the screen might have defective pixels but then stating that ''This is not a malfunction.'' The Sony screen had two tiny built-in speakers of such poor quality that they were shamed by a pair of external speakers I bought for $15.At $559, the I.B.M. T560 was not the least expensive screen I tried, but it was by far my favorite. The gymnast of the monitor world, it has a cleverly engineered base that allows the screen to be rotated 90 degrees, so that a horizontal screen can be turned into a vertical one. Two clicks on an on-screen button reorient the image. The monitor can even flip backward to display information to someone sitting on the other side of a desk.It sounds like a gimmick, but I found the T560's rotation feature to be a revelation. Some activities, like basic typing or using Microsoft Outlook, are made for a vertical screen. David Hill, the director of design for I.B.M.'s personal computing division, said that the horizontal, or ''landscape,'' display became dominant in the early days of PC's because it accommodated programming information better. The T560 give users both options, a feat that no C.R.T. monitor can easily duplicate.None of this means that C.R.T.'s are about to disappear. Paradoxically, high-end users in the graphic arts may be the last holdouts, amid a debate about the absolute accuracy of colors on the liquid crystal display screens. ''This isn't really an issue at the consumer level,'' said Christopher Connery, a manager of the L.C.D. product line at NEC. ''But for people like animators at Pixar, when it comes to full-motion color material, C.R.T.'s will have advantages over L.C.D.'s for years to come in the same way that conventional photography has advantages over digital imaging.''But for ordinary users for whom space is at a premium or who find that conventional displays tire their eyes, L.C.D.'s may finally be worth the cost.

Mixed Emotions in Wisconsin Town Foxconn Picked for Plant

RACINE, Wis. - Residents of the southeastern Wisconsin town where Foxconn Technology Group plans a massive display screen plant greeted the announcement with excitement about the possible economic boost and wistfulness about how the community's changing landscape.Foxconn announced the location of its planned factory after months of negotiations with the company and the village of Mount Pleasant in Racine County. The company has said it intends to build a campus with about 20 million square feet of office space over 1.56 square miles, eventually employing as many as 13,000 people to manufacture liquid crystal display screens used on phones, televisions, computers and other devices.Tammy Graceffa, 54, the owner of the Hiawatha Bar and Grill just south of the plant's expected location, said the influx of workers and her land's possible purchase could bring her financial gains. But still, she found the moment bittersweet."Where we grew up and were raised will no longer be farm fields. It will be concrete and industry," she said. "You can't go back and say, 'This is the road where we used to play ball.'"The Wisconsin legislature approved a $3 billion incentive package for Foxconn - contingent on the company fulfilling its jobs promise, and the state's economic development agency is working on the final contract. The intended industrial complex would be the largest in the state."I think it's going to be really good. The economy ought to pick its way up around here. It's been dragging a little here in Racine (County)," said Michael Rosenbaum, a village trustee in the town of Sturtevant, just a few miles from Mount Pleasant.Rosenbaum said he understands there are landowners who are unhappy about being displaced, but hopes Foxconn will "make sure that they get a decent deal.""You can have another dream home. That's my feeling," he said.But some landowners said they felt like they didn't have much choice."It's the Foxconn train. Get on or get run over," said Katie Spencer, 27.Gonzalo Perez, meanwhile, is already brainstorming ways to get more people to his restaurant, the House of Castlewood. The 50-year-old Mexican immigrant who bought the diner in December said he's toying with the idea of having a buffet so when the future workers come they can come in and out quicker.His restaurant is in Sturtevant but it's just across the highway from the planned factory."This is like something of a miracle happening here because nobody expected that kind of business would come to a small town like Sturtevant," he said.The Associated Press

Cheapest Galaxy S8 Where to Buy the Latest Handset and Get ...

SAMSUNG'S Galaxy S8 smartphone has finally been unveiled- and now we reveal where you can buy the high-end gadget at the best price.Customers who order the device by April 19 will be able to get the handset eight days before its official launch.The phone comes in two sizes and two different colours - the S8 and S8 - and will officially be available to buy in theUK on April 28, with the S8 costing 689 and the S8 779.It comes with a larger screen that fills up most of the face of the device and the home button has been removed in favour of a pressure sensitive "invisible" home button embedded in the display screen.The S8 has a 5.8in screen and the S8 a 6.2in display, with both devices also becoming the first to house the tech giant's new artificial intelligence software, virtual assistant Bixby It's the first phone from Samsung since the Note7 was discontinued over safety concerns and battery fires Both devices come with a 12 megapixel rear camera and an eight megapixel front-facing camera, as well 64GB of storage that can be expanded up to 256GB via a MicroSD card slot.The S8 and S8 are also both dust and water resistant and have fast charging capabilities.If you're already in a contract then the best way to find a new deal is by using a comparison service to match you to your perfect plan.Billmonitor compares your previous three months usage to work out how much you're actually using. You'll need to sign in using your details from your online mobile account.It only works for customers of EE, O2, Tesco Mobile, Three and Vodafone.Another similar comparison tool, MobilePhoneChecker has a similar feature to Billmonitor but it's not as comprehensive.Mobile firms are clever. They know people want to get the latest smartphone as soon as possible at a price that seems manageable but when you add this up, you might realise you're overpaying.For example, a network offering you a 45 a month contract over 24 months with an upfront cost of 99 = 1,179 Once you minus the cost of the handset (1,179 - 689) you will see that you're really paying 20.41 a month for your contract.One of the most cost-effective ways to buy the iPhone is by buying it up-front - but with a hefty 689 price tag this might not be possible.If you can then it's worth looking at SIM-only deals as they generally offer a cheaper alternative than getting a contract with the network.The best contract deal depends on how much you use your phone.
