What are the maintenance methods of a touch screen monitor?

We are a touch monitor supplier.Our company mainly produces all kinds of LED TVs, computer monitors, all in one computers, advertising monitors and smart mirrors. All of our products can be customized, and you can have your own logo on them.What are the maintenance methods of touch screen monitor? In the era of rapid development of science and technology, touch screen display has been widely used. No matter in the shopping mall, or in the hotel, the hall or even some road sections of the street, the touch screen display screen has provided great convenience for our work and life, and it has been closely related to our life. In the cost-effective touch screen display life is also relatively long, even so we still need to pay attention to its maintenance. Here is a brief introduction to the four major maintenance methods. 1. Therefore, lianchengfa recommends that consumers pay attention to the above four points when using the touch screen display, properly protect and maintain the correct use of the touch screen display, and try to use it for the longest time, so as to avoid unnecessary economic losses.2. Do not let it produce electrostatic effectWe all know that the electrostatic effect is easy to penetrate the capacitance screen. Although the glass on the surface of the capacitance screen of the touch screen display has certain anti-static treatment, it can only bear the static electricity under certain strength. Therefore, when selecting the protective film of the touch screen display, we must pay more attention to it, and try to select the protective film with strong anti-static ability.Touch Panel3. Do not let the strong magnetic field close to the touch screenThe electromagnetic field must be avoided when using the magnetic field, because the magnetic field will cause the temporary aging of the capacitor screen. However, you also need to pay attention to the sound and other magnetic things, so try not to let it close to the touch screen display as much as possible.4. Do not use in high temperature environmentDo not use in high temperature environment. When the ambient temperature reaches 40 or above, it is easy to cause the capacitive screen drift of touch screen display. If this happens for a long time, it will cause serious damage or even scrap of touch screen display. It is very inconvenient for companies or individuals to cause economic losses.After reading, I have a certain understanding of the maintenance of led touch screen monitor. We will continue to update the common sense about LED large screen. Thank you for your attention.What are the maintenance methods of a touch screen monitor?

Which iPod touch would be best for me?

I think you would be ok with an 16GB. I have the 16GB touch and its fine for me. Also, you really should get some screen protectors because the oil in your skin will eventually wear down the touch screen, eventually resulting in the screen not operating properly. And, if your a fanatic about mint things, I would highly recommend a hard case. Hope this helped.

How to Make the Frequency Converter Run at the Frequency When the Frequency Is Written on the Touch Screen
How to Make the Frequency Converter Run at the Frequency When the Frequency Is Written on the Touch Screen
(source: Rongji igniter)The touch screen is a man-machine interface. Our commonly used mobile phone input is also a touch screen, which is a capacitive screen. When fingers massage the touch screen interface, there will be a change in capacitance, and the chip in the mobile phone will sense this change and convert it into a voltage signal, that is, a standard analog quantity (if a point is a switching value, the switching value can be regarded as a special analog value), and then read it through the single chip microcomputer for easy processing, which represents some information. Generally, the resistance screen is used in industry, and the reason is similar.Whether it's resistance, capacitance or even ultrasonic waves, they are just an induction medium. They are installed on the outermost side of the touch screen, which is called the touch panel. There is also a layer of glass inside, which is used for display, called liquid crystal. The two are separated. When the finger touches the touch panel, the industrial touch screen senses a certain amount of resistance. If it's just a point, it's OK Directly output a switching value to the single chip microcomputer. The single chip microcomputer has drawn up a standard, and you will know what action significance you require it to perform.Similarly, you can also output an analog quantity on the touch screen interface, which can be regarded as a multi-channel resistance signal, that is, it represents the output of a group of continuous analog quantity modes to the single chip microcomputer, and then quantified into multi-channel switching quantity. Generally, the accuracy is poor. For example, you can use 8-bit switching quantity to represent an analog quantity. The frequency of the frequency converter you said is generally 0-50Hz, while 8-bit on The closing value corresponds to 0-255 (2 ^ 8) For example, 00000001 represents 1Hz, 00000011 represents 3Hz, 00001111 represents 15Hz, and so on. Each frequency value has a digital quantity corresponding to it. This process is the so-called coding, because the single chip microcomputer only knows the binary code, it is necessary to quantify the analog quantity in decimal system into 01 binary code, and each code corresponds to a unique physical meaning.When you output 15Hz to the touch screen, the touch screen actually stores an 8-bit binary code such as 00001111. Then this code is stored in the register on the circuit. Then, to transmit this code to the frequency converter, the touch screen needs to be completed through some communication protocols, such as 485 and 232 at the bottom. This What are these communication protocols? They can be simply understood as a transmission and "translation process".For example, if you are Chinese and want to communicate with an American, you speak Chinese and Americans speak English, but each word referred to will have a corresponding standard. If you set such a standard, you can understand each other. For example, the Chinese "morning" corresponds to the English "morning". So you say the Chinese "morning" When the translator hears it, he will say it as the corresponding English "morning" to the Americans.The 15Hz of the touch screen should be transmitted to the frequency converter. In fact, it is to transmit the 8-bit data such as 00001111 of the touch screen to the frequency converter. The 01 code is essentially a pulse. From the perspective of the circuit, as long as there are two lines, one high level and one low level, so that the pulses can be sent one by one in a certain order. If you want to transmit faster, improve the pulse accuracy The frequency, that is, the baud rate and other parameters can be set. The data sent each time is a series of pulses in a group, which is a "frame". After sending one "frame", stop a little and send another "frame" Of course, in the process of transmission, it is also necessary to let the other party know what type of data this is and consider the data reliability. Therefore, some start bits, stop bits, check bits, etc. are required, because in the data sent at one time, the data is a little longer than the upper 8 bits, such as 10 bits.In the design of the frequency converter, of course, these receiving circuits are also considered. Each time it receives a series of pulses, it will read it into its single chip microcomputer, and then judge the meaning and function of this data, that is, after translation, it knows what it means. Because in the touch screen, the frequency code is not necessarily 15Hz, which is 00001111, which is also It may be 00001100, so it needs to change it into the corresponding 00001100 first, and then adjust the PWM control IGBT module to perform the operation of this frequency.

How Many Technology Types Does the Touch Screen Have
How Many Technology Types Does the Touch Screen Have
Touch screen technology is a direct operation technology based on gesture. Direct manipulation is the ability to manipulate the digital world on the screen. Touch screen is an electronic visual display, which can detect and locate the touch on its display area. This usually refers to touching the display of the device with a finger or hand. This technology is widely used in computers, user interaction machines, smart phones, tablets and so on to replace most of the functions of mouse and keyboard.Touch screen technology has existed for many years, but recently, advanced touch screen technology has developed by leaps and bounds. The company incorporated this technology into more products. The three most common touch screen technologies include resistive, capacitive and saw (surface acoustic wave). Most low-end touch screen devices are included in a standard printed circuit board and are used for SPI protocol. The system has two parts: hardware and software. The hardware architecture includes an independent embedded system using 8-bit microcontroller, several types of interfaces and driving circuits. The system software driver is developed using interactive C programming language.Type of touch screen technology: touch screen is a two-dimensional sensing device, which is made of two pieces of material separated by gaskets. There are four main touch screen technologies: resistive, capacitive, surface acoustic wave (SAW) and infrared (IR).Resistance: the resistive touch screen is composed of a flexible top layer made of polyethylene and a rigid bottom layer made of glass separated by insulation points, and is connected to the touch screen controller. The resistive touch screen panel is more affordable, but provides only 75% of the light monitor, and the layer may be damaged by sharp objects. Resistive touch screen is divided into 4-wire, 5-wire, 6-wire, 7-wire and 8-wire resistive touch screen. The structural design of all these modules is similar, but there is a major difference in each method of determining touch coordinates.Capacitance: the capacitive touch screen panel is coated with material for storing charge. The capacitive system can transmit up to 90% of the light from the display. It falls into two categories. In surface capacitance technology, only one side of the insulator is coated with a conductive layer. Whenever a person's finger touches the screen, charge conduction occurs on the uncoated layer, resulting in the formation of a dynamic capacitor. Then, the controller detects the touch position by measuring the capacitance change at the four corners of the screen.In projection capacitance technology, a conductive layer (indium tin oxide) is etched to form a grid of multiple horizontal and vertical electrodes. It involves sensing along the X and Y axes using a clear etched ITO pattern. In order to improve the accuracy of the system, the projection screen includes a sensor in each interaction of rows and columns.Infrared: in infrared touch screen technology, X and y-axis arrays are equipped with paired infrared lamps and photodetectors. Whenever the user touches the screen, the photodetector will detect the light image emitted by the LED.Surface acoustic wave: surface acoustic wave technology includes placing two sensors and some reflectors along the X and Y axes of the display glass plate. When the screen is touched, waves are absorbed and a touch is detected at this point. These reflectors reflect all electrical signals sent from one sensor to another. This technology provides good pass through and quality.

Virtual Touch Screen
Virtual Touch Screen
Virtual touch screenA virtual touch screen (VTS) is a user interface system that augments virtual objects into reality either through a projector or optical display using sensors to track a person's interaction with the object. For instance, using a display and a rear projector system a person could create images that look three-dimensional and appear to float in midair. Some systems utilize an optical head-mounted display to augment the virtual objects onto the transparent display utilizing sensors to determine visual and physical interactions with the virtual objects projected. .------Can I use "Prev instead of "Previous on a button?Words are really unnecessary, since arrows are used on a lot of standard image galleries online. You could have the arrows shown all the time or when the user moves the mouse or touches the touch screen. Fading the arrows out after a time-out gives the user enough cues to know there are more images to see. My daughter Hanna, age 7, using a hammer for the first time assembling IKEA furniture. It's easy to see there are previous and next images on this screen shot. Arrows fade out if I stop moving my mouse. com.------Are touch screen laptops good for gaming?Thatu2019s like asking if a black keyboard is better than a white keyboard for gaming. It has no impact on the ability of your computer to play video games. Youu2019ll pay more for a touch screen laptop with similar specs as a non touch screen laptop. But if youu2019re gaming, you are using a mouse and keyboard anyway, so the touchscreen is irrelevant.Now, if youu2019re asking whether or not you can actually use the touchscreen to play your game, that depends entirely on whether or not the game you are playing is designed for it. Odds are, though, if youu2019re playing a game on a laptop, it was not designed for a touchscreen. And even if your touchscreen works, it probably wonu2019t be nearly as responsive as a mouse and keyboard unless you are dealing with some very high end tech.Are touch screen laptops good for gaming?------iPad Touch Screen Not Working?

It is reported that Apple plans to use cheaper LCD screens on most iPhone models next year, while delaying the full conversion to high-tech organic light emitting diode (OLED) screens, which also reflects consumers' price sensitivity.According to the Wall Street Journal, apple is expected to launch an LCD model and two OLED models this fall, and the LCD model is expected to account for most of its iPhone sales. It is expected that Apple will continue to use LCD next year, which is completely inconsistent with the previous report of a complete transition to OLED.Apple announced in March that it was testing its internal microled screen.Apple's decision to insist on using cheaper LCD screens has brought more uncertainty to its screen suppliers; In addition, Apple's decision to produce its own screen endangers the interests of many suppliers.Since apple is not expected to use these products in its OLED screen, the shares of Apple's three LCD suppliers, including sharp, LG display and Japan display, have fallen sharply in the past year. Subsequently, when it was revealed in March that Apple was already testing its microled screen, the shares of many display suppliers, including Samsung, sharp and LG display, fell again. This also damages the interests of general display and Synaptics. After reports showed that Apple would use more LCD screens than expected, the share price of general display company, which provides OLED display materials, began to fall.The Wall Street Journal pointed out that Apple's decision to postpone the implementation of OLED screens does not necessarily bring opportunities for LCD suppliers. For example, LG display has planned to invest in OLED screens.Apple has been facing the problem of supply shortage in the past. If suppliers have to change their production plans, Apple may face supply shortage again. It is reported that Japan display raised $320 million in April to meet the expected demand for its advanced LCD.According to recent reports, Apple has communicated its transformation plan to its suppliers, including plans to reduce parts procurement from suppliers by nearly 20% this year. At the same time, the uncertainty of the continuous expansion of Apple's supply chain will also make the new iPhone more expensive than ever.

Principle of Touch Screen Capacitance Screen_ What Are the Application Areas of Touch Screen
Principle of Touch Screen Capacitance Screen_ What Are the Application Areas of Touch Screen
Principle of touch screen capacitance screenTouch screen is the most friendly computer user interface at present. It is more and more widely used in consumer electronic products. The touch detection device and touch screen controller are good. The mechanical structure of the detection device is damaged in the process of touch screen device, resulting in the decline of touch accuracy and shortening of service life of the touch screen; In addition, the cost of commonly used capacitive and resistive touch screens is relatively high. Inductive touch screen can avoid damage to the touch detection device during touch and prolong the service life of touch screen products.The working principle of inductive touch screen, as well as the hardware circuit and part of the program design of the controller, all of the controller circuits have passed the verification. The non-direct contact touch of inductive touch screen avoids the damage to the touch detection device, prolongs the service life of the whole touch control system, and the repetition accuracy and touch sensitivity of touching the same point meet the expected design requirements.The capacitive induction touch screen is not affected by dirt, dust or oil stains, but it will be affected by the surrounding environment to varying degrees because it adopts the electric field coupling principle. At the same time, the capacitive induction touch screen has serious drift phenomenon.What are the application areas of touch screenTouch screen has become a hot spot in the market. In the market, shopping malls, hotels and other places, it is still dominated by smart phones. The growth momentum of the smartphone market slowed down and entered a period of gentle development. The application of touch screen outside mobile phones, such as automotive electronics, retail, medical treatment, public facilities, leisure and entertainment, will promote the rapid growth of touch screen market.In addition to applications in large fields, touch screens can be innovated in subdivided fields. In the field of "pen writing tablet", innovate the touch screen.The products have been extended to tablet with pen writing function, e-book, all-in-one machine, electronic whiteboard, etc. And the pen and hand can be used at the same time. When one hand is touching, the pen can also write at the same time.The traditional materials of capacitive touch screen are ITO, metal grid, nano silver wire, carbon nanotube, conductive polymer, graphene, etc. Metal mesh and nano silver wire have more supporters. Both materials are metals (silver or copper) and their conductivity is better than ITO.
Screen Fingerprint Identification Will Be Applied to LCD Screen, Not Just OLED
Screen Fingerprint Identification Will Be Applied to LCD Screen, Not Just OLED
Fingerprint identification on mobile phones has become an indispensable part of our daily life.Especially during the epidemic, face recognition is mostly paralyzed due to wearing masks, and fingerprint recognition has become the current optimal solution.Of course, if you use a mobile phone without fingerprint identification such as iPhone x, you have to find a way by yourself...9to5mac also gave a tutorial on using face ID with mask Screen fingerprint identification has become the mainstream, and the technology is also very mature. However, Tony saw a news while surfing the Internet today, saying that Tianma, a domestic LCD and LCM design company, released the world's first LCD Screen multi-point fingerprint identification scheme (Ted finger print, referred to as TFP).The strength of this scheme is that the off-screen fingerprint identification mobile phones we use now are basically OLED screens, while the LCD screen basically has no on-screen fingerprint identification...One plus 6T off screen fingerprint identification diagram As we all know, the screen fingerprint unlocking needs the illumination of the light source for fingerprint identification, but the LCD screen is relatively thick and has poor light transmittance; Second, the LCD screen cannot emit light actively, and the backlight will interfere with the identification of optical fingerprints.These two problems make LCD basically bid farewell to screen fingerprint recognition.Therefore, mobile phones with LCD screen basically adopt side fingerprint identification, and some will be combined with the power key on the side of the mobile phone.But OLED screens don't have this problem. Because the OLED screen is thinner and more transparent, it is natural to use fingerprints on and off the screen.Then why do manufacturers not directly on the OLED screen, but want to operate madly on the LCD screen? The reason is also simple: because LCD screens are cheap...Although Lu Weibing, vice president of Xiaomi, said publicly some time ago that Hongmi team successfully realized fingerprint recognition under LCD screen on a redmi note8 Pro prototype, so far, no manufacturer has officially announced this technology, and Tianma is the first.So Tony was surprised when he saw the news. This fingerprint identification scheme can be said to break through the two obstacles of current screen fingerprint identification technology - LCD screen and identification area.If the multi-point fingerprint identification in the LCD screen can achieve mass production, it means that the LCD screen can also use fingerprint identification!Another point is the identification area of off screen fingerprint identification.So far, the identification area of screen fingerprint is basically fixed, almost at the lower position of the screen. People will subconsciously put their fingers at the approximate position when unlocking the mobile phone.But no one can guarantee that every time the finger is pressed on the fingerprint identification area, because the identification area is so large, it is inevitable that there will be deviations...The scheme announced by Tianma this time shows that it can make the whole LCD screen recognize fingerprints!Tony mended his brain, that is, I could identify my fingerprint and unlock my mobile phone by placing my finger anywhere on the screen.If this multi-point fingerprint identification technology can be mass produced, the efficiency of unlocking the screen will be much higher than now. You don't have to find the identification area and poke it on the screen.It can be said that Tianma's operation directly makes the LCD screen ride on the head of OLED in fingerprint identification. Once LCD screens didn't even deserve fingerprint identification. Now they not only have fingerprint identification, but also can identify 5 at a time...As for why the multi-point fingerprint solution in the TFP screen can realize these functions, high integration has played a great role.In short, it is to integrate touch, display and fingerprint identification, replace the previous design of fingerprint identification module and reduce the thickness of the screen, so that the screen fingerprint identification is feasible on the LCD.At the same time, in order to realize fingerprint identification on the whole screen, Tianma covers the whole screen with optical path and sensors.As for how multi-point fingerprint identification can play new tricks, it still depends on the subsequent operations of manufacturers.As for the fate of LCD screen after mass production of this scheme, we still don't know, but before that, LCD screen has never been the first choice for mobile phone manufacturers.After all, the OLED screen is thinner, can emit light by itself, and the color is more bright. The experience is much better than that of LCD, but there are still problems of stroboscopic and screen burning, and the price is relatively expensive.When it comes to the LCD screen, the advantages and disadvantages are reversed...The price of iPhone 11 with LCD screen is lower For most users, OLED screen is their first choice, but there are still a group of people who stick to the LCD screen.In addition to having a larger viewing angle, another reason is that they can't accept the strobe of OLED screen. They think it's really hurting their eyes...Therefore, once the TFP scheme realizes mass production, the defect that the LCD screen has no off screen fingerprint will be supplemented. If the price can be controlled well, the current situation of the screen in the mobile phone market may change a lot.However, before that, the mobile phone market was still dominated by OLED screens, not to mention the suoper AMOLED screens such as Samsung. The evolution of LCD screens has a long way to go...
