General Description Samsung Secret
Description
LTA320HN03 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 32.0" 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
SPVA(Super Patterned 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 (2pixel/clock)
