How to Deal with the Flower Screen on LCD Display Screen

This or that problem may occur during the use of any product. LCD display is fragile, and you should be particularly careful in use. Friends often encounter problems about LCD display flower screen. Then what is the general reason for LCD display flower screen, and how to deal with LCD display flower screen? Take a look with Xiaobian with these questions.

How to Deal with the Flower Screen on LCD Display Screen 1

The LCD display screen is blurred, and the picture shakes badly. Sometimes even the icons and text can't be seen clearly, but it will return to normal after one or two minutes. This phenomenon mostly occurs in wet weather, which is due to moisture inside the display. To completely solve this problem, use the moisture-proof sand in the food packaging to string it with cotton thread, then open the back cover of the display, and hang the moisture-proof sand near the tube seat at the tail of the tube neck of the display tube. In this way, even in wet weather, the above "problems" will not appear again.

The LCD display screen has a flower screen and color lines appear on the display screen. In fact, to solve this problem, we should first know that there are two main reasons for the appearance of color lines: first, if it is a full screen color line or a color line that appears with the change of display content, usually their position is not fixed and generally will not fill the whole screen, Most of this is caused by problems with the graphics card, such as overheating of the video memory or driver errors. The general treatment is to reinstall and set the graphics card driver. If the graphics card is overclocked, please also reduce the rated power, clean the graphics card fan or heat sink and strengthen the heat dissipation of the chassis.

Secondly, if the LCD display screen has one or more lines covering the whole screen, even if the display content changes, the position and color of the lines do not change. Most of the reasons are problems with the control chip or wiring of the LCD display screen. Such problems can only be sent to the LCD display screen manufacturer for maintenance.

Cob Display Screen Splicing Screen, What Advantages Will It Have
Cob Display Screen Splicing Screen, What Advantages Will It Have
There are several kinds of splicing screens, and LED display screen is one of them. Cob display screen is one of the LED display screen series products. The spliced display screen makes the display screen clearer and more delicate, and the color is softer and more beautiful.What is unacceptable about the splicing screen is the obvious splicing. The existence of splicing will affect the display screen, resulting in the disharmony of the screen and the linear decline of user experience. Therefore, under many materials, the splicing of LED display screen is ideal. If the splicing seam is 0.1 and close to 0, the overall display screen fits perfectly.What are the advantages of cob display splicing, one of the LED display product series?Cob display screen was born when SMD packaging was difficult to drill down with a smaller spacing. One of the characteristics is that the spacing can easily achieve a point spacing smaller than that of LED. Secondly, the packaging method is different. Cob packaging directly encapsulates the light-emitting chip on the PCB board and is bonded with epoxy resin, so that the device is not exposed and has stronger protection. Therefore, the large screen spliced by cob display has the following characteristics:1. The flatness of the screen body is higher and the screen surface is smoother;2. The display screen is clearer, the color is more beautiful, and there is no sense of particles at a close distance;3. Stronger heat dissipation capacity, no heat accumulation;4. The product has stronger protective performance and is not afraid of damage;5. Get rid of point light and area light, and the light quality is better;At present, there are few manufacturers of cob splicing screen, which has high entry requirements and difficult enterprise transformation... And for the same model, the price of cob display screen will be 10-20% higher than that of SMD encapsulated led with small spacing. For questions about cob splicing screen, you can contact the cob splicing screen manufacturer - Shenzhen Dayuan, and we will give you a better reply.fqj
Application of High Performance Optical Film in Automobile Display Screen
Application of High Performance Optical Film in Automobile Display Screen
With the continuous improvement of people's requirements for the lighting and display instruments of automobile instrument panel in terms of brightness, visual effect and energy consumption, in view of the significant advantages of high-performance optical film in adjusting the optical path, it is possible to replace the traditional plastic film for automobile display screen and instrument panel. In this paper, polycarbonate (PC) film with unique surface microstructure is introduced, and its improvement effect on contrast and brightness is verified by experiments.Figure 1 example of automobile display screensummaryAt present, the market demand for the brightness, visual effect and energy consumption of automotive instrument panel lighting and display instruments is increasing. Ordinary transparent or frosted printed grade plastic film has been used to provide the necessary local diffuse reflection effect to mask the bulb and structural details behind the display screen, and allow light to pass through when there is lighting demand. However, sufficient brightness and contrast need to be achieved by increasing additional lighting intensity and appropriate surface texture treatment. At this time, the application of such films may be limited.Figure 2 printed PC film for instrument panelIt is gratifying that in the LCD TV and display application market, the latest development of high-performance optical films has made it possible to extend the adjustment function of such films to some optical paths to the application of automotive display and instrument panel.Generally, the optical function is realized by creating optical microstructure (such as microlens array, semi cylinder or prism array) on the film surface. Such films are particularly suitable for applications where LEDs are used as lighting sources.Figure 3 refraction law: light refraction (N2 = 1 for air)In this paper, two types of films are evaluated: one is the film with microlens array on the surface; The other is a film with random matte texture (as a reference). The film surface is screen printed with a pattern similar to the common instrument panel, which is placed in the backlight module for testing, and then the brightness and contrast of the module are qualitatively and quantitatively evaluated by light intensity measurement method.
The Negative Impact of LED Display Screen, Inventory Some Disadvantages of LED Display Screen
The Negative Impact of LED Display Screen, Inventory Some Disadvantages of LED Display Screen
LED display screen undoubtedly plays an important role in the current urban development. Around our lives, we can almost see the shadow of LED display screen, which brings us a lot of convenience; But everything has two sides. While bringing benefits to us, it will certainly leave a negative impact. Today, Maipu Guangcai will check some disadvantages of some LED displays with you.LED display1. Urban "psoriasis" caused by aging, along with urban development and planning changes caused by urbanization process, some LED displays installed earlier have been unable to adapt to the latest planning and construction. In addition, due to their long service life, there are often adverse reactions such as flower screen and "Caterpillar" phenomenon during operation, which not only affect the viewing and publicity effect, It also has a negative impact on the urban environment. Therefore, this kind of urban "psoriasis" is often the first batch of targets to be cleaned up and rectified.2. The risk of spontaneous combustion of LED screen. For a long time, the safety of outdoor LED display screen has something to do with the rapid expansion of Maipu Guangcai outdoor LED display screen Market in the early stage. The causes of accidents can be basically divided into "natural disaster" and "man-made disaster". The former belongs to line aging and short circuit caused by long-term disrepair and negligent management; The latter is a man-made potential safety hazard in order to save cost.3. In the second and third tier cities, we can often see LED advertising vehicles. In order to make the publicity cover as wide as possible, some manufacturers often choose to transform them into LED advertising vehicles by loading LED display screens and sound amplification equipment for vehicles privately. According to relevant laws and regulations, without the approval of relevant departments, no unit or individual shall set up advertisements on the body of traffic vehicles (except buses) or broadcast outdoor advertisements in the form of loaded electronic screen and audio. Once investigated and punished, they will face the punishment of removing billboards or fines. However, this privately transformed advertising car has not been approved by relevant departments. It often unilaterally pursues volume and brightness for publicity effect. In addition, it drives slowly on the road during the peak period for publicity needs, so it is very easy to bring great road traffic hidden dangers.4. Light pollution, as early as the 1930s, the international astronomical community put forward the concept of light pollution. However, light pollution has not been paid attention to until recent years. More and more outdoor LED advertising displays in cities have inevitably become one of the manufacturers of light pollution. In addition, some led practitioners unilaterally pursue high brightness or use high brightness light sources to cover the defects of products in order to meet the market demand, which intensifies the severity of light pollution to a certain extent.Therefore, when we choose LED display products in the later stage, we should try our best to save energy, environmental protection and safety of the products, and think of the future disassembly when installing them, and install them reasonably according to the environment, so as to avoid future generations from spending a lot of time and energy to deal with them.fqj

The change of each generation seems to form a tacit understanding. According to what standard is it divided? This is inseparable from vivo, a mobile phone manufacturer.Vivo is the first manufacturer in the mobile phone industry to introduce screen fingerprint unlocking, so that users can experience a faster unlocking mode. Each time vivo launches a representative model, it constantly refreshes the innovation of screen fingerprint. As for vivo, it has become a representative brand and powerful promoter of screen fingerprint. Later, everyone agreed to use vivo's new products, Partition algebra as screen fingerprint.Vivo's achievements in screen fingerprint technology and how it came all the way should also start from the beginning of this technology. Two years ago, screen fingerprint was the product of a concept machine. People thought it was ahead of schedule and didn't take it seriously. Vivo made its first attempt in 2017. At the 2017 MWC conference, vivo showed the xplay 6 mobile phone, used screen fingerprint for the first time, and used ultrasonic scheme, which triggered a lot of discussion that year.The first attempt of xplay 6 laid the foundation and saw the development of screen fingerprint. No one expected that in January 2018, vivo launched a mass production machine vivo X20 plus UD. This mobile phone uses an OLED screen. Taking advantage of the self luminous characteristics of the OLED screen, it adopts an optical fingerprint identification scheme to project the fingerprint sensor optically onto the screen to unlock. This model is the originator of screen fingerprint, so it is logical that this mobile phone is defined as the first generation of screen fingerprint mobile phone.Only two months later, in March 2018, vivo launched vivo X21, which is called the second generation screen fingerprint phone. This generation has made improvements in recognition rate and accuracy, and has a higher recognition rate than the previous generation. Because vivo quickly implemented a new unlocking technology in two months, this mobile phone has been sought after and sold more than one million. After vivo X21 was highly praised, other manufacturers began to chase it, and vivo led to the popularization of this technology. Vivo launched the first super high-end flagship machine nex of the new series. Compared with the previous generation, the fingerprint image accuracy of this machine is improved by 50% and the unlocking speed is improved by 10%. It is designated as the third generation screen fingerprint.The success of the first three generations of screen fingerprint technology has further inspired the development of vivo. In September, vivo launched vivo x23 model. The screen fingerprint has built-in f / 1.5 large aperture to increase the light input and improve the efficiency. In addition, the new photoelectric scheme is used to make the fingerprint imaging clearer. By adding the on-screen fingerprint DSP acceleration technology, the mobile phone can be unlocked in 0.35 seconds. In this way, it has become the benchmark of the fourth generation screen fingerprint technology.At the end of the year, vivo launched a mobile phone with another concept, vivo nex dual screen version. The screen fingerprint of this mobile phone is upgraded from 2p lens to 3P lens, and updated to f / 1.2 super aperture. The light input is increased again, and the identification and unlocking efficiency is further improved, reaching the unlocking speed of 0.29 seconds. DSP hardware acceleration technology was further updated, and the performance was improved by 17%, becoming the fifth generation screen fingerprint. The five generation screen fingerprint five combos in 2018 make vivo synonymous with screen fingerprint unlocking.In 2019, vivo has invested 10 billion in scientific and technological innovation and has also established R & D bases around the world. The rapid improvement of screen fingerprint technology is inseparable from the huge investment and the efforts of the R & D team. At the beginning of the year, the new iqoo sub brand carried the screen fingerprint technology as soon as it appeared. Even the mid-range cost-effective model vivo Z5 also benefited. Users pursuing cost performance can also enjoy this advanced technology.With the support of strong strength, the sixth generation screen fingerprint HD version was born. On this year's vivo x27, the sensor sensing area has doubled, the finger detection area has increased by 27%, and the image semaphore and dynamic range have increased by 30%. In addition, a simulation scheme is formulated for the actual environment. For example, the recognition rate of dry and wet fingers is increased by 50%, and the recognition rate is also improved in the low-temperature environment of the great enemy of fingerprint unlocking.From the development of the previous six generations of screen fingerprint, vivo has become the leader of mobile phone screen fingerprint technology in China, which is inseparable from vivo's pursuit of technology and fashion. It has been unremitting in pursuing the pioneer of science and technology, making the screen fingerprint from scratch to mature and stable, showing vivo's spirit of innovation. The two 5g mobile phones iqoo Pro 5g and nex 3 5g launched in the second half of this year use a new generation of screen fingerprint technology, and several new models are waiting to appear later. Along the way, we can look forward to vivo's screen fingerprint technology.

Some companies also claim to have achieved this for the military, but its effectiveness is questionable because all the PR around it uses still images and mock-ups.The trick would be to pick up the light from all directions and re-produce that same scatter on the other side (or from the screen). There are ways of making things 'invisible' to some wavelengths using refraction to bend EM waves around a central object, but it's unlikely this would work for an arbitrarily placed 'screen', unless you could capture the input with a bundle of fibre optics and somehow reproduce it exactly at the other end (without 'twisting' of the outbound scatter).All that seems quite hazy and far too under-developed for the practical application you are seeking here. Probably the best you could achieve would be a 3D lenticular screen with head/eye tracking so that it could manipulate the image according to the screen/head relative position. This would only work for one person at a time with current technology, as far as I know. The input would then need to be processed into a 3D scene so that it could be re-displayed from other angles. This technology is reasonably mature and there are many technologies ranging from pure camera-based visible-light capturing with software processing, to active 3D scanning cameras that combine multiple active and passive inputs. Alternatively a tightly packed 2D array of cameras could be used and two suitable ones selected to match the relative head-screen orientation. Their field-of-view would still need to be manipulated according to the head-screen distance, this would most likely be easier to do digitally by cropping and scaling the image from a wide-angle lens
Interpretation of Various Chromaticity Processing Technologies of LED Display Screen
Interpretation of Various Chromaticity Processing Technologies of LED Display Screen
LED display technology from the monochrome display in the early 1980s, to the double primary color display in the late 1980s, and then to the three primary color (full-color) display in the mid-1990s. Until today, we have widely discussed the multi primary color (greater than three primary colors) processing technology in the field of flat panel display. The chromaticity processing technology of LED display screen ranges from the most basic primary color wavelength selection, to the allocation of white field color temperature, to the color space transformation processing to improve the color reduction degree and the chromaticity uniformity processing to improve the image quality. Until today, we have adopted the multi primary color (greater than three primary colors) processing in order to expand the color gamut and reproduce more natural colors. Various color processing technologies run through the development history of LED display screen and become one of the core technologies in the comprehensive discipline of LED display screen.Various color processing technologies1. Selection of primary color wavelengthLED display screen is widely used in all walks of life, and there are different requirements for the primary color wavelength of LED in different application places. Some of the selection of the primary color wavelength of LED is to achieve good visual effect, some is to meet people's habits, and some are the provisions of industry standards, national standards and even international standards. For example, the selection of the primary color wavelength of the green tube in the full-color LED display screen; In the early days, yellow green LEDs with a wavelength of 570nm were widely used. Although the cost was low, the color gamut of the display screen was small, the color reduction degree was poor and the brightness was low. After selecting the pure green tube with the wavelength of 525nm, the color gamut of the display screen is nearly doubled, and the color reduction is greatly improved, which greatly improves the visual effect of the display screen. Another example is the stock market display. People are usually used to using red to indicate the rise of stock prices, green to indicate the decline of stock prices, and $to indicate flat prices. In the transportation industry, the national standard strictly stipulates that the blue-green band indicates passage and the red band is prohibited. Therefore, the selection of primary color wavelength is one of the important links of LED display screen.2. Allocation of white field color coordinatesWhite field color coordinate allocation is one of the most basic technologies of full-color LED display. However, in the mid-1990s, due to the lack of industry standards and basic testing methods, the white field color coordinates were usually determined only by human eyes and feelings, resulting in serious color deviation and randomness of white field color temperature. With the promulgation of industry standards and the completion of testing methods, many manufacturers began to standardize the color matching process of full-color screen. However, due to the lack of theoretical guidance of color matching, some manufacturers often allocate 100 field color coordinates at the expense of the gray level of some primary colors, and the comprehensive performance can not be improved.3. Chroma uniformity treatment.The chromaticity uniformity of LED display screen has always been a major problem perplexing people in the industry. It is generally believed that the uneven brightness of LED can be corrected at a single point to improve the brightness uniformity. The chromaticity unevenness cannot be corrected, and can only be improved by subdividing and screening the LED color coordinates.As people have higher and higher requirements for LED display screen, only subdividing and screening led color coordinates can not meet people's critical eyes. It is feasible to comprehensively correct the display screen and improve the chromaticity uniformity.We find that even the same LED of the first international brand has large wavelength deviation and color saturation deviation, and the deviation range greatly exceeds the threshold of human eyes for green color difference identification. Therefore, it is of great significance to correct the chromaticity uniformity.In CIE1931 chromaticity diagram, according to the law of the center of gravity, we find that the color coordinates of the mixed color can be adjusted to the intersection o of the straight line Cr and the straight line dB when green is mixed with a certain proportion of red and blue at any point within the range of G (& square; ABCD)Although the chromaticity uniformity can be greatly improved. However, the corrected color saturation decreases significantly. At the same time, another premise of using red and blue to correct the uniformity of green chromaticity is that the three red, green and blue LEDs in the same pixel should be centrally distributed as far as possible, so that the color mixing distance of red, green and blue can be as close as possible, so as to achieve better results. At present, the industry usually adopts the LED uniform distribution method, which will bring confusion to the chromaticity uniformity correction. In addition, how to measure the color coordinates of tens of thousands of red, green and blue LED is also an extremely difficult problem. We gave a hint.4. Color restoration processingThe birth of pure blue and green LED makes the full-color LED display popular in the industry with its wide color gamut and high brightness. However, due to the large deviation between the chromaticity coordinates of red, green and blue LED and that of PAL TV (see Table 1), the color restoration degree of LED full-color screen is poor. Especially in the performance of human skin color, there are obvious visual deviations. Therefore, color restoration technology came into being. Here, the author recommends two methods of color restoration:First, the color coordinate space of red, green and blue LED is transformed to make the three primary color coordinates between LED and PAL TV as close as possible, so as to greatly improve the color restoration degree of LED display screen. However, this method greatly reduces the color gamut range of LED display screen and greatly reduces the color saturation of the picture.Second, only the most sensitive skin color gamut of human eyes is properly corrected; The color gamut that is not sensitive to other human eyes should reduce the original color saturation as little as possible. In this way, a balance can be obtained between color reduction and color saturation.5. 3 2 multi primary color chroma processing methodEverything recovers in spring. Under the blue sky, the green grass is green; In autumn, wheat waves roll; Under the sun, it was golden. The colorful nature is so beautiful. Unfortunately, the existing LED display screen can not fully reproduce this beautiful scenery. Although LEDs belong to monochromatic light, each color LED still has a half wave width of about 30 50nm, so its color saturation is limited. It can be seen from Figure 3 that the color saturation of LED full-color screen is seriously insufficient in the large natural color rich $and cyan areas.In recent years, in the field of flat panel display, they are keen to discuss 3 3 multi primary color display (red, green, blue plus yellow, green and purple) to expand the color gamut and reproduce more abundant natural colors. Then, can the LED display realize 3 3 multi primary color display?We know that in the visible light range, yellow and green are monochromatic light. We already have $, cyan LEDs with high saturation. While purple is polychromatic light, single chip purple LED does not exist. Although we can not achieve red, green, blue plus yellow, green and purple 3 3 multi primary color LED display. However, it is feasible to study red, green, blue plus yellow and green 3 2 multi primary color LED displays. Due to the existence of a large number of high saturation colors and Cyans in nature; Therefore, this study is of certain value.In the current TV standards, the video source has only three primary colors of red, green and blue, but no two colors of yellow and green. Then, how to drive the yellow and green primary colors of the display terminal? In fact, when determining the driving intensity of yellow and green primary colors; We follow the following three principles:(1) The purpose of adding yellow and green primary colors is to expand the color gamut and improve the color saturation. The overall brightness value cannot be changed;(2) The hue shall not be changed while increasing the color saturation;(3) Centered on D65; Take the rygcb gamut boundary as the endpoint, and make linear expansion at each point within the gamut range.Under the guidance of the above three principles; According to the law of gravity center, we can find a 3 2 multi primary color chroma processing method. However, in order to truly realize the 3 2 multi primary color full-color screen, we have to overcome the lack of brightness of yellow and cyan LEDs; At present, it is limited to theoretical discussion.To sum up, we mainly discussed three aspects:(1) How to improve the chromaticity uniformity of LED display screen;(2) How to improve the color restoration of LED display screen;(3) How to expand the color gamut and restore more natural colors.When the above chroma processing technologies are implemented, they are interrelated, and in some aspects, even fish and bear's paw can't have both. The integrated LED display screen also needs brightness uniformity correction, gray nonlinear transformation, noise reduction processing, image enhancement processing, dynamic pixel processing, etc. the whole signal processing process is very complex. Therefore, we must comprehensively weigh various performances from the perspective of system, grasp the order of various processing, and increase the depth of signal processing, so as to make the LED full-color display show a colorful and colorful world.
