General Description Samsung Secret
Description
LTI550HJ03 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
SPVA(Super Patterned Vertical Align) mode
Wide viewing angle ( 178 )
