Product Information

General Description

*Description

LTA460WS-L03 is a color active matrix TFT (Thin Film Transistor) liquid crystal display
(LCD) that uses amorphous silicon TFTs as a switching devices. This model is composed
of a TFT LCD panel, a driver circuit and a back-light system. The resolution of a 46.0"
contains 1366 x 768 pixels and can display up to 16.7 million colors with wide viewing
angle of 89° or higher in all directions.

*Features

- High contrast ratio, high aperture structure

- SPVA(Super Patterned Vertical Align) mode

- Wide viewing angle(±178°)

- High speed response

- WXGA (1366 x 768 pixels) resolution (16:9)

- Low Power consumption

- Direct Type 24 CCFTs(Cold Cathode Fluorescent Tube)

- LVDS (Low Voltage Differential Signal) interface. (1pixel/clock)

* Applications

Home-alone Multimedia TFT-LCD TV
Display terminals for AV application products
High Definition TV (HDTV)

Note 1) Test Equipment Setup

The measurement should be executed in a stable, windless and dark room
between 30min and 40min after lighting the back-light at the given temperature
for stabilization of the back-light. This should be measured in the center of screen.
