General Description
Description
LTA400WS-L02 is a color active matrix liquid crystal display (LCD) that uses amorphous
silicon TFT(Thin Film Transistor) as switching components. This model is composed of a
TFT LCD panel, a driver circuit and a back light unit. The resolution of a 40.0" is
1366 x 768 and this model can display up to 16.7 million colors with wide viewing angle of
89 or higher in all directions. This panel is intended to support applications to provide a
excellent performance for Flat Panel Display such as Home-alone Multimedia TFT-LCD
TV, Display terminals for AV application products, and High Definition TV (HDTV).
