STRUCTURE AND FUNCTIONS
A TFT color LCD module comprises a TFT LCD panel, LSIs for driving liquid crystal, and the backlight. The
TFT LCD panel is composed of a TFT array glass substrate superimposed on a color filter glass substrate with
liquid crystal filled in the narrow gap between two substrates. The backlight apparatus is located on the backside
of the LCD 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.
