LED display module TM121TDSG02

TFT LCDLCD/ISTNtouch screen

TFT LCD Module A TFT LCD has a liquid crystal layer between a glass substrate formed with TFTs and transparent pixel electrodes and another glass substrate with a color filter (RGB) and transparent counter electrodes. Each pixel in an active matrix is paired with a transistor that includes capacitor which gives each sub-pixel the ability to retain its charge, instead of requiring an electrical charge sent each time it needed to be changed. This means that TFT LCD displays are more responsive. STRUCTURE AND PRINCIPLE Color LCD module TM121TDSG02 is composed of the amorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film Transistor) array and a backlight. The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the TFT array glass substrate and a color-filter glass substrate. Color (Red, Green, Blue) data signals from a host system (e.g. signal generator, etc.) are modulated into best form for active matrix system by a signal processing board, and sent to the driver LSIs which drive the individual TFT arrays. The TFT array as an electro-optical switch regulates the amount of transmitted light from the backlight assembly, when it is controlled by data signals. -Size:12.1 inch -Voltage:3.3V -Display area:246.0 (H) × 184.5 (V) mm -Technology Type:a-Si TFT -Pixel pitch：0.240(H) × 0.240 (V) mm -Display Mode：Transmissive,Normally white -Surface Treatment：AG -Viewing Direction；full view -With /Without TSP:Without TSP -Backlight:White-LED -Interface:LVDS
