How to make the LED display screen more high-definition

Improve the contrast of the LED display: Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. Increase the gray level of the LED display: the gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest of the single primary color brightness. The higher the gray level of the LED display, the richer the color , The color is brighter; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. Nowadays, many LED display manufacturers can set the gray scale of the display to 14bit~16bit, so that the image level can distinguish the details and the display effect is more delicate, vivid, and colorful. Narrowing the dot pitch of the LED display: narrowing the dot pitch of the LED display can greatly improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of ​​the LED display, and the more details that can be displayed More, the screen display is more delicate and lifelike. The combination of LED display and video processor: The LED video processor can use

The working principle for the LCD screen panels

How Does An LCD Screen Work? Answering A Liquid Crystal Display Tech Question #LCD #Tech   You can find Liquid Crystal Display (LCD) technology everywhere: in TVs, computers, tablets, laptops, smartphones, watches, monitors, displays, calculators, cellphones, smartwatches, and many more… but do you know how this awesome tech works?

So today, we explain how an LCD screen work by looking inside an LCD screen and detailing all of its layers. We will talk about the reflector sheet, the Light Guide Plate (LGP), the Dual Brightness Enhancement Film (DBEF), the diffuser sheet, the prism sheet, the bottom polarizer, the bottom glass substrate (backplane), the Thin Film Transistor (TFT), the Liquid Crystal, the Common electrode, the color filter (RGB), the top glass substrate, the top polarizer, and the top chassis and frame. Understanding how a screen works can be especially handy to know if you like clever technology or to understand if your screen breaks down, and you need to figure out what is going on to repair it… knowledge is power!

What we should do at this time? Now we would like to share with you the causes and solutions of LCD screen flashing: The frequency of the LCD screen itself is too high, resulting in the flash screen. However, in real life, it is rare for the device to flash due to high frequency. According to the industry technical personnel, people’s naked eyes have no sense of flicker for images over 60Hz, while the design standard of general LCD screens is basically within this data range, so under normal circumstances, the frequency will not be too high, but at the same time, the screen itself will not be excluded from failure. After testing by relevant instruments, it is really the fault of the screen itself. In addition to replacing the new monochrome LCD screen, it is to design the software related to the equipment. LCD flash screen solution: the best way is to increase the OSC frequency of IC to see the flash of LCD screen. Of course, if the LCD has separate row and column drivers, it can also be adjusted by setting the driver chip.   The frequency of LCD is close to that of light source. This is very common. Because the frequency of different light source is different, in some specific cases, when the frequency
