STRUCTURE AND FUNCTIONS

A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are connected to the panel, the backlight assembly is attached 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 driver 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.

Supply Voltage Sequence
(1) Please note that the supply voltage must not be applied to the module while the control signals (SEL, UP,
DOWN, EXIT, LEFT, RIGHT and RESET) are connected to GND. Otherwise the module may cause malfunction.
(2) If the power supply voltage is applied while UP and DOWN are connected to GND, the input control signals
become an ineffective mode. To reset this mode, turn off the power once and turn on the power while UP and DOWN are connected to GND. Then, the mode will be released.
(3) Do not change MENUSEL setting while the module is operated.
MENUSEL selection (Hierarchical type or Toggle type) is set when the power supply voltage is applied.
(4) Inverter current wave
Inverter current wave is as follows.
