1. OVERVIEW
CLAA200UA02 is 20.0” color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module
composed of LCD panel, driver ICs, control circuit and backlight. By applying 6bit+Hi-FRC digital data,
1600*900, 16.7M-color images are displayed on the 20.0” diagonal screen. Input power voltage is 5.0V
for LCD driving. Inverter for backlight is not included in this module. General specification are
summarized in the following table:

4).The life time of the lamp is related to the current of the lamp, so please according to the
description of the “(b) backlight” on page 8.
5).Test Condition: IEC 1000-4-2
VESDt: Contact discharge to input connector; VESDC: Contact discharge to module
6).If you operate the product in normal temperature range, the center surface of panel should be
under 60℃.
7).When lamp current is out of the absolute maximum range, the life will fall rapidly or shown
unusual sign.
IL min 2mA only for test only, but we can’t guarantee the lifetime and performance.
8).Delay lighting testing needs the volt above start voltage Vrms. Before the procedure tube needs
typical lighting for 1 minute and stay in the temperature 25±2℃ for 24 hours and then testing
in the same condition in dark room.
