General Description

Description

LTA460WS-L04 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 46.0“ 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).

Features

 RoHS compliance (Pb-free)
 High contrast ratio, high aperture ratio, fast response time
 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)
 DE(Data Enable) mode
 LVDS (Low Voltage Differential Signaling) interface (1pixel/clock)

Note (1) 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.

Single lamp current : 6.0mA
