AND-TFT-5PA*

320 x 234 Pixels
LCD Color Monitor

The AND-TFT-5PA is a compact full color TFT LCD module,
whose driving board is capable of converting composite
video signals to the proper interface of LCD panel and is
suitable for security, car TV, portable DVD and GPS
applications. It can accept NTSC & PAL video signal input.

This device consists of a twisted nematic (TN) liquid crystal
cell, that incorporates a TFT-array that has 320 x 234 pixels
on a 5 inch diagonal screen, X and Y drivers, an LSI
controller, and a built-in CCFL backlight and inverter (with
optional board.)
