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? Do you also know that the working principle of LCD is pretty similar to the newer LED backlit based screens (edge LED or direct LED)? 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!

With the progress of science and technology, LCD is more and more popular. However, the inherent and inevitable shortcomings of LCD have also been paid attention to. When it comes to LCD black spots, many people may not understand. Today, I will teach you how to look at black spots. I hope it can help you.   What is the dark spot of LCD? In fact, dark spot is more hidden than bright spot and bad spot, but its influence on use is far greater than bad spot. Sometimes on some screens, there will be some patches that are not very big. The black small class is as big as the soybean, and the big class may be as big as the thumb. Different from the bright and dark spots, the dark color system is only partially dark, which is not easy to find from the front, but only from the side.   The main reason for the formation of dark spots is that the external force has been squeezed for long time. We think that it is probably due to improper handling in the transportation process. LCD screens with black dots are usually hard to find on the front and more obvious on the side (just like the test perspective).We suggest that when you buy LCD, you should not only look at the bad points of the screen, but also look at the surface of the screen from multiple angles, and set the screen to white. If you find

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
