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.)
Features
• Compatible with NTSC and PAL system
• Pixel in stripe configuration
• 5 inch (13 cm) diagonal screen
• High brightness CCFL backlight (400 Nits)
• Slim and compact
• Vcom Toggle Imager Reversion: Up/Down and Left/Righ
1/4 VGA resolution
• High performance, low consumption
RoHS compliant
*ALSO AVAILABLE: AND-TFT-5PA-DHB (high bright backlight installed- 500
nits)
