Sony LCX007BKA Datasheet

3.4cm (1.35-inch) Color LCD Panel
Description
The LCX007AKA is a 3.4cm diagonal active matrix TFT-LCD panel addressed by polycrystalline silicon super thin film transistors with built-in peripheral driving circuit, and it provides a full-color representation. (The LCX007BKA is designed for direct viewing with polarizer attached on its both sides.)
This panel provides a wide aspect ratio of 16:9, such as those represented in HD. The built-in side­black function also allows an aspect ratio of 4:3 in the NTSC/PAL mode.
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 system and control signals.

Input Equivalent Circuit
To prevent static charges, protective diodes are provided for each pin except the power supply. In addition, protective resistors are added to all pins except video signal input. All pins are connected to Vss with a high resistance of 1M(typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)
