General Description

Description

LTA320WT-L05 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 32.0” 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 and High Definition TV.

Features

- Test Equipment Setup

The measurement should be executed in a stable, windless and dark room between
40min and 60min after lighting the back light at the given temperature for stabilization
of the back light. This should be measured in the center of screen.
