General Description

SAMSUNG SECRET

Description

LTA550HQ03 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 55.0” is 1920 x 1080 and this model can display up to1.07 Billion

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.
