General Description

Samsung Secret

Description

LTA550HQ20 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 to 1.07 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

Features

 RoHS compliance (Pb-free)

 High contrast ratio & aperture ratio with wide color gamut

 SVA(Super Vertical Align) mode  Wide viewing angle (±178°)  High speed response

 FHD resolution (16:9)

 Low Power consumption  Edge Type LED (Light Emitted Diode) BLU  DE (Data Enable) mode  2ch LVDS (Low Voltage Differential Signaling) interface
