General Description

SAMSUNG SECRET

Description

LTA400HM05 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 1920 x 1080 and this model can display up to16.7 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

 RoHS compliance (Pb-free)

 High contrast & aperture ratio

 SPVA (Super Patterned Vertical Align) mode

 Wide viewing angle (±178°)

 High speed response

 FHD resolution (16:9)

 Low Power consumption

 12CCFLs (Cold Cathode Fluorescent Lamp)

 DE (Data Enable) mode

 LVDS (Low Voltage Differential Signaling) Interface

- 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.
