Touch Screen Monitor/Non-Touch LCD monitor Of the two types of LCDs, touch screens are the most commonly used.   Resistive touch screen monitors or capacitive touch screen monitors are user-friendly and more efficient to operate. Here are more advantages and disadvantages of touch/non-touch LCD monitors:   Advantages   Touch screen monitors do not require a keyboard or mouse, and can be operated directly with fingers, making it more convenient and user-friendly.   Disadvantages   The only disadvantage of non-touch LCD monitors is the lack of intuitiveness in operation details.   3. Latest LCD Monitors Technology   With the rapid development of technology, many latest LCD monitor technologies are gradually emerging.   In terms of technology, 4K monitor, HDR monitor technology, screen type, monitor connection, etc. are all trends worth paying attention to. Summary   In short, if you need to focus on choosing an LCD monitor, the key consideration is whether the LCD monitor you choose meets your needs and scenarios. I hope that the introduction of different types of LCD monitor technology and the latest technology in this blog will be helpful to you.

In today's technological age, display screens are an indispensable part of our daily lives.   When customizing display screens, we often see an important parameter-contrast. So, is the higher the contrast of the display screen, the better? This article will explore this issue in depth. First, we need to understand the concept of contrast.   1. What is contrast   Contrast refers to the degree of difference in brightness when the display displays black and white. Specifically, it refers to the brightness ratio of the same point on the screen when it is brightest (displaying white) and darkest (displaying black), which is a ratio of large in front and small in the back.   The higher the contrast, the more layers there are between light and dark, the display can achieve a smoother transition, and the more expressive the picture is. High-contrast displays can present richer colors and clearer pictures.   To a certain extent, the higher the contrast, the better the display effect.   High-contrast displays can show more delicate color changes and more vivid black and white contrast, giving the audience a stronger visual impact.   For professional fields, such as photography, design, video production, etc., high-contrast displays can better present works and improve work efficiency.   2. What are the types of contrast   The contrast we are familiar with is divided into two types, one is static contrast and the other is dynamic contrast.   Static contrast = white screen brightness / black screen brightness, basically in the thousands (1000:1). Generally, the contrast of IPS screens is around 800~1500:1, the contrast of VA screens is 3000~4000:1, and the contrast of TN screens is generally only 600~800:1. The larger the number in front, it is usually called "higher contrast". Dynamic contrast refers to the contrast value measured under certain specific conditions, that is, the brightness ratio of the brightest and darkest parts of the screen at a certain moment. Its main function is to ensure that the brightness of bright scenes and dim scenes are dark enough.   Therefore, dynamic contrast has a more obvious practical significance for applications that need to switch between bright and dim scenes frequently.   It should be noted that the contrast of the display generally refers to static contrast, and dynamic contrast does not have much reference value for comparison.   3. Is the higher the contrast, the better?   It should be noted that the higher the contrast, the better. This rule only applies within a certain range. If it exceeds the reasonable brightness of the display, the higher the contrast will have the opposite effect, resulting in reduced screen clarity and affecting the visual experience. So, what kind of contrast is suitable?   Generally speaking, a contrast ratio between 1000:1 and 3000:1 is considered to be a good display.   For ordinary users, the contrast ratio within this range is sufficient to meet daily needs.   For professional users, a higher contrast display can be selected according to work needs.   For example, for gamers, when choosing a gaming monitor, you can refer to the screen material, brightness, contrast, etc. In fact, the optimal value of contrast varies depending on the display and the objective external conditions.   When customizing an LCD Monitor, it should be determined based on your user needs and viewing comfort. Too high or too low a contrast ratio may have a negative impact on the visual experience.   4. The impact of the contrast ratio of the LCD screen on the display effect   In an LCD screen, contrast is achieved by adjusting the backlight brightness.   High-contrast LCD screens can still maintain high brightness under darker backlights.   Low-contrast LCD screens need brighter backlights to maintain high brightness.   Therefore, high-contrast LCD monitors can better restore the details and colors of images, while also reducing eye fatigue and discomfort.   In addition to the impact on the display effect, contrast also has an important impact on the power consumption and life of the LCD screen.   High-contrast LCD screens usually require higher backlight brightness, so they consume more electricity. In addition, the backlight life of high-contrast LCD screens will also be shorter than that of low-contrast LCD screens.   Therefore, when selecting an LCD screen, you must look at the contrast parameter rationally and choose it based on actual needs to customize the LCD display screen that best suits your user.   In summary, LED monitor contrast is one of the important factors affecting the display effect. High contrast can bring clearer and more realistic picture effects; but it also requires more electricity and a shorter backlight life. Therefore, when choosing an LCD screen monitor, you need to choose a suitable contrast according to your actual situation.  

Liquid crystal display technology is an important driving force for the development of modern electronic products. According to different uses, LCD monitors can be further divided into commercial use, personal consumption, industrial use and special enhanced types.   Among LCD monitors for commercial use, they occupy an important market share with their unique performance and application occasions. Next, let's take a closer look at the concept, advantages and application examples of commercial LCD monitors in commercial environments. 1. What is a commercial LCD monitor   Commercial LCD, referred to as commercial LCD, is a display device designed for commercial environments. Compared with home LCDs, commercial LCDs pay more attention to stability, durability, and functionality to meet the long-term and high-intensity use needs of commercial users. Commercial LCDs usually use IPS or VA panels to provide clear and stable image quality, suitable for long-term content playback. Commercial displays are displays designed specifically for commercial applications, commonly used in enterprises, governments, medical care, education and other fields. 2. What are the advantages of commercial LCD monitors   1. Superior picture display effect: Professional LCD monitors use advanced display technology, such as IPS or VA panels, which can provide excellent color display and wide viewing angles, and can obtain clear images from any position.   2. High stability and durability: Business LCD monitors have undergone strict quality control and durability testing, and can operate stably in high temperature, low temperature, and high humidity environments.   3. Versatility: Commercial-grade displays often have multiple input interfaces, such as HDMI, DVI, VGA, etc., which are convenient for connecting various devices. In addition, with the further development of technology, many commercial LCD screens also support multi-screen display to meet the needs of different commercial purposes.   4. Easy maintenance: The design of Public display pays more attention to the convenience of daily maintenance and upgrades. Most commercial LCDs adopt a modular design, which is convenient for users to replace parts or make repairs. In addition, their OSD menus are designed to be concise and clear, making it convenient for users to adjust settings.   5. Long life: The design life of Industrial-grade LCD monitor is usually more than 50,000 to 60,000 hours, which can meet the needs of commercial users for long-term use.   6. Environmental protection and energy saving: Digital signage displays use low-power chips and can work at low voltages, which is in line with the concept of green environmental protection.   3. Why do companies choose commercial displays for office work?   For office workers, facing heavy work pressure, they need a good commercial display. Whether it is the convenience brought to you during operation, the visual enjoyment brought by the picture quality, or the high level of work quality guaranteed from a professional perspective. For enterprises, such a humanized professional commercial display is more needed. So what kind of display can be called a good commercial display?   1. 4K ultra-clear picture quality: accurate presentation of picture details   Details determine success or failure, and picture quality determines details! Higher-definition display resolution often helps to gain insight into the subtle details of the picture and truly achieve "every detail is visible".   Based on this, Oscan uses IPS technology ultra-high-definition display panels for commercial display LCD modules, matching 3840×2160 ultra-high-definition resolution to make the details of the picture clearly presented, and can accurately control the subtle defects in image processing, presenting a fine, thorough and lifelike picture, bringing a higher-definition and more detailed sensory experience. 2. Fast and smooth: create smooth and flowing   With high refresh characteristics, smooth and flowing, one screen can achieve smooth and flowing.   The commercial display used by OSCAN LCD display module is different from the traditional low refresh rate commercial display with frequent screen input delay. It has a high refresh rate of 144Hz and a grayscale response time of 1ms (MPRT)/4ms. Whether it is office creation, web browsing or video editing, it can reduce screen tearing and jamming, reduce input delay, and work more smoothly.   3. Low blue light eye protection: What is more important than health Don't forget to save body costs while saving energy costs. Long-term office work will inevitably cause eye fatigue. The blue light in the LED light source in general displays will cause damage to the eyes.   The wavelength of blue light is between 400-500 nanometers, which is the shortest wavelength in visible light. The shorter the wavelength, the stronger the energy. Therefore, the high-energy short-wave blue light closest to ultraviolet rays will cause permanent damage to the eyes.   However, the damage caused by blue light is closely related to the length of time used for eyes. If you don't stare at the screen for a long time, the damage is still very small.   It is recommended that people who use computers for office work for a long time can choose some business monitors with eye protection functions.    It can be seen that commercial monitors are more distinctive than ordinary home monitors in terms of workmanship and function, and are suitable for long-term office use. As an office monitor, the commercial LCD screen has a larger screen and a better screen-to-body ratio, which further improves work efficiency.   If you want to do your work well, you must first sharpen your tools. Embracing the digital economy is inseparable from the empowerment of commercial terminals. At present, the digital economy is developing rapidly. From servers to commercial PCs, the commercial terminal market will show a booming trend and become an important cornerstone for the digital transformation of various industries.

LCD monitors are ultra-thin display devices with thin bodies, space saving, power saving, no high temperature, low radiation, good health, and soft images that do not hurt the eyes. However, compared with traditional CRT monitors, the life of LCD monitors is significantly shorter. Among the various components of LCD and LED monitors, the LCD panel is the core, which accounts for 80% of the total cost of LCD monitors. The lamp in the component determines how long the LCD monitor has a life span. When the lamp brightness is reduced to 50%, the life span is defined. During such a usage period, the brightness changes with time. It presents a decreasing curve, so the longer the TFT LCD monitor is used, the lower the brightness will be.   At present, the life of the LED backlight of the LCD Display can reach more than 5W hours, and the brightness decay rate can be controlled within 3% of 10,000 hours. If it is used for 8 hours a day, it can be used normally for 15 years, but attention should be paid to the use environment and related matters.    The following are some suggestions to increase the service life of the LCD monitor:   1. It is recommended to work in a normal temperature/normal humidity environment. High temperature/high humidity will affect the life of the LCD monitor.   2. Intense temperature fluctuations will affect the performance of the LCD monitor, especially low temperatures will affect the brightness and response time. It is recommended to work in a stable and clean environment. Dust will cause internal circuit failure.   3. Do not let liquid splash into the monitor. If you need to clean it, please turn off the power, spray the detergent on a soft cloth and then wipe it gently.   4. The LCD monitor is a glass product. Avoid collision and vibration when moving it.   5. There are multiple layers of film on the surface of the LCD monitor. It is strictly forbidden to scratch it with a sharp tool.   6. It is strictly forbidden to disassemble the LCD monitor at will. If there is a fault, be sure to ask a professional to repair it.   7. Displaying a fixed screen for a long time will reduce the brightness and increase the image retention phenomenon. It is recommended to use a screen saver.   8. Please turn off the monitor power and unplug the power plug if you don't use it for a long time.

Lines that appear on your computer display can be caused by a variety of factors, including hardware problems, software problems, or connection problems. The following 7 - 22 Inch Monitors are the most likely situations and solutions:   Reconnect the video cable: Check that the video cable (such as HDMI, VGA, Display Port, etc.) is firmly connected to the computer and the monitor. Sometimes a loose or damaged cable can cause the lines to appear.   Replace the video cable: If the line persists, try replacing the video cable to make sure there is no problem with the cable itself.   Adjust the resolution and refresh rate: In the monitor display settings of your computer, try adjusting the screen resolution and refresh rate. Sometimes mismatched settings can cause lines to appear.   Check the pc monitor settings: Check if there are any configuration options in the monitor menu that can solve the line problem, such as clarity, sharpness, color, etc. settings.   Update the graphics card driver: Make sure the graphics card driver is the latest version. You can find the graphics card in Device Manager and try to update the driver.   Check for hardware failure: Lines may be a sign of a hardware problem with the monitor or graphics card. Try connecting another monitor to determine if the problem is associated with a specific monitor. If the problem persists with a different monitor, it may be a problem with the graphics card.   Check your computer hardware: If you suspect the lines are caused by a hardware problem, such as a graphics card failure or memory problem, try reinstalling or replacing the hardware.   Reduce electromagnetic interference: Keep your computer away from electronic devices and other objects that may cause interference to reduce the possibility of lines appearing.

LCD screens may have some problems during long-term use, such as white screen, flowery screen, black screen, dark screen, yellowing, white spots, bright lines, bright bands, dark lines, dark bands, outer film scratches, etc. What should I do?When the LCD screen has the above faults, how should we troubleshoot and solve the problem? Today we has sorted out 2 common faults and solutions for LCD screens for you, so save them quickly!A: LCD screen white screen fault1. First, determine whether the fault is in the switching power supply, signal processing part, or TCON part.2. The fault range can be determined by measuring the LVDS signal connecting the signal processing part and the TCON part. If it is normal, the TCON part at the back end is suspected; if it is abnormal, check the signal processing part at the front.3. For the TCON part inspection, the main checks are: key point voltage and RSDS line connectivity.4. There are two situations for white screen:a) There is signal input, the whole screen is white, and the image is not clear. This is caused by a fault in the control circuit board;c) There is signal input, the whole screen is white, and the image can be seen, but the image seems to be covered by a layer of fog. This is caused by a bad cell. It cannot be repaired and the LCD screen needs to be replaced.5. Check three voltages:a) 10V (or 12V), which is a voltage generated by a simple boost of the 5V (or 3.3V) screen power supply voltage.b) 25V (or 30V), which is output by the DC---DC circuit.c) Negative 7 volts, which is also output by the DC---DC circuit. If these three voltages are normal, then consider whether the main chip is poorly soldered or damaged. Another key point to check is the screen cable, to see if the screen cable is installed in place and whether it has good contact. If necessary, clean the screen cable. In addition, the first thing to check for the DC---DC conversion circuit of the screen is the filter capacitor, and the second is that the IC of the DC--DC circuit is often broken.6. Characters are blurred or tailed: Check the VGA signal line, and focus on whether the ground wire of the R.G.B three-color line is connected normally → Replace the screen line or adapter board → Rewrite the driver → Change the driver board → LCD screen backplane signal interface IC is broken → LCD screen backplane contrast potentiometer adjustment → LCD screen light guide plate is misaligned → - Polarizer is wrong.7. The screen displays an error prompt "out of frequency range": Check the signal line → Rewrite the MCU driver → Replace the EPROM → Rewrite the EPROM program → Change the driver board.8. After power on, the white screen appears backlight without pressing the switch button: After pressing the button, the image can be displayed normally, which is caused by the reverse connection of the switch signal and ADJ signal of the high-voltage board interface. Some of the switch signal outputs of the driver board MCU are abnormal, which can be rewritten The program can be repaired or the MCU can be replaced.B: LCD screen black screen failureIt may be a bad built-in power supply or a bad driver board inside the machine. Troubleshooting method: Check whether the power output is normal. If there is no output, it can be confirmed that the power supply is bad. If the power output is normal, it may be that the driver board is bad.1. The LCD screen panel black screen failure is first caused by abnormal power supply circuit:First check whether the 12V and 5V voltages are normal. If the 5V voltage is abnormal, it may be caused by the input level of the power supply circuit or the increased load.After troubleshooting and replacing the faulty components, the 5V voltage may return to normal, but it may still not be able to boot up. This may be related to the MCU program or its own damage. If you cannot find the original replacement board, you can consider purchasing a replacement board. 2. The second situation is that the power supply is normal, the key response of the panel is also normal, and the screen is black:The power supply is normal, the key response is normal, but the screen is black.
