The LCX038AST is a 1.8cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with a built-in peripheral driving circuit. Use of three LCX038AST panels provides a full-color representation. The striped arrangement suitable for data projectors is capable of displaying fine text and vertical lines. The adoption of DMS1 structure and high light resistance structure realize a high luminance screen. And cross talk free circuit and ghost free circuit contribute to high picture quality. This panel has a polysilicon TFT high-speed scanner and built-in function to display images up/down and/or right/left inverse. The built-in 5V interface circuit leads to lower voltage of timing and control signals. The panel contains an active area variable circuit which supports S-XGA 5:4 and PC-98 8:5 data signals by changing the active area according to the type of input signal.
