Description

LTA400XXXX 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 to 1.07G 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, Display terminals for AV application products, and High Definition TV (HDTV).

Features

 RoHS compliance (Pb-free)  High contrast ratio, high aperture ratio, fast response time  SPVA (Super Patterned Vertical Align) mode  Wide viewing angle (·89¶)  Full HD (1920 x 1080 pixels) resolution (16:9)  Low Power consumption  WLED (White Light Emitting Diode) Backlight  LVDS (Low Voltage Differential Signaling) interface
