NL8060AC31-12G 2 structure and functions a color tft (thin film transistor) lcd module is comprised o f a tft liquid crystal panel structure, lsis for driving the tft array, and a backlight assembly. the tft pa nel structure is created by sandwiching liquid crystal material in the narrow gap between a tft array glass substra te and a color filter glass substrate. after the driver lsis are connected to the panel, the backlight assembly is a ttached to the backside of the panel. rgb (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the d river lsis which in turn addresses the individual tft cells. acting as an electro-optical switch, each tft cell regulates light transmission from the backlight assembly when activated by the data source. by regulating the amount of light passing through the array of red, green, and blue dots, color images are created with clarity. block diagram digital signal processor lcd timing controller power supply circuit level shift h-driver backlight v-driver 2400 lines 600 lines tft lcd panel h : 800 3 (r, g, b) v : 600 lsls drivers r0 ? r5 g0 ? g5 b0 ? b5 clk hsnyc vsnyc de v cc v ddb brtc brthl brth brtl gnd gndb inverter mva outline of characteristics (at room temperature) display area 246.0 (h) 184.5 (v) mm drive system a-si tft active matrix display colors 262144 colors number of pixels 800 600 pixels pixel arrangement rgb vertical stripe pixel pitch 0.3075 (h) 0.3075 (v) mm module size 280.0 (h) 210.0 (v) 13.0 typ.
