1. OVERVIEW

CLAA220WA09 is 21.6” color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module
composed of LCD panel, driver ICs, control circuit and backlight. By applying 6 bit digital data,
1680×1050, 16.7M-color images are displayed on the 21.6” diagonal screen. Input power voltage is 5.0V
for LCD driving. Inverter for backlight is not included in this module. General specification is
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 7.

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.
