AND-TFT-5VX-4HB-KIT

640 x 480 Pixels
LCD Color Monitor

The AND-TFT-5VX-KIT 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 computer peripheral, industrial meter,
image communication and multi media.

This device consists of an amorphous silicon panel with
back-light, incorporating a TFT-array that has 640 x 480
pixels on a 5 inch diagonal screen, with pixel in stripe
configuration, 262,144 display colors and a TTL transmission
interface.

• Amorphous silicon TFT LCD panel with back-lit unit

• Pixel in stripe configuration

• Light weight and slim

• Displays 262,144 colors

• Optimum Viewing Direction: 6 o’clock

•

Portrait mode

• TTL transmission interface

•

RoHS compliant

Note 1 : In order to satisfy the quality of B/L, no matter what inverter is used, the output lamp current must be between
Min. and Max. to avoid the abnormal display image caused by B/L.

Note 2 : The waveform of lamp driving voltage should be as close to a perfect sine wave as possible.

Note 3 : The “Max of starting voltage” means the minimum voltage of inverter turns on the CCFL and it should be applied to
the lamp for more than 1 second to start up. Otherwise the lamp may not be turned on.
