GENERAL DESCRIPTION

DESCRIPTION

LTN121XA-L01 is a color active matrix TFT (Thin Film Transistor) liquid crystal display

(LCD)that uses amorphous silicon TFT as a switching devices. This model is composed

of a TFTLCD panel, a driver circuit and a back-light system. The resolution of a 12.1 ″ contains 1024 x 768 pixels and can display up to 262,144colors. 6 o'clock direction is the optimum viewing angle.

FEATURES

• Ultra Thin and light weight

• High contrast ratio

• XGA (1024x768 pixels) resolution

• Low power consumption

• DE (Data enable) only mode.

• 3.3V LVDS Interface with 1 pixel / clock
