China 2.0 inch Capacitive tft lcd touch panel FT6336 Manufacturers, Suppliers, Factory

​An LCD display module is an electronic component used for displaying characters, symbols, and graphics in a clear, easy-to-read format. It typically consists of a liquid crystal display (LCD) panel, a driver circuit board, and other supporting components, such as backlighting and a controller chip.

Conventional 5 inch display screens cannot be seen clearly under strong outdoor sunlight unless they have a brightness of 2000 lumens. To achieve this brightness, the number of high-brightness LED lights needs to be increased, which will increase power consumption and reduce battery life. Our company has successfully mass-produced a semi-transparent and semi-reflective 5 inch screen with a resolution of 800*480 and an RGB interface. It can display clearly in the sun without turning on the LED light, which reduces the power consumption of the machine and is the first choice for many outdoor electronic devices.

The LCD screen itself does not emit light, and a backlight needs to be added to the back of the glass for normal display. This involves how to test the surface brightness and backlight uniformity of the LCD screen. The brightness of the LCD screen surface and backlight brightness are measured through BM -7 equipment test, the test is more accurate when the display is powered normally and displays a solid color picture.

Polarizer is one of the important materials of liquid crystal display. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple lamination, stretching, coating and other processes. , can realize liquid crystal display high brightness, high contrast characteristics. Polarizers account for about 10% of the cost of TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels.

LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.
