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.

LCX007BKA

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 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (The resistor value: typ.)
