1. OVERVIEW

CLAA185WA04 is 18.51” 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,
1366*768, 16.7M-color images are displayed on the 18.51” diagonal screen. Input power voltage is 5.0V
for LCD driving. Converter for backlight is not included in this module. General specification are
summarized in the following table:
