driver lsis for driving the tft (thin film transistor) array, touch panel (t/p) 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 pr ocessing 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. color images are created by regulating the amount of transmitted light through the tft array of red, green and blue dots. 1.2 application x
