1. OVERVIEW
CLAA201VA07 is 20" color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module composed of LCD Panel, Driver ICs, Control Circuit Board, Backlight. By applying 6 bit+FRC digital data, 640 480, 16.2M-color images are displayed on the 20" diagonal screen. Input power voltage is 5.0V for LCD driving and interface of data and control signals is CMOS. Inverter for backlight is not included in this module. General specifications are summarized in the following table:

[Note] If the driving waveform of lamp is asymmetric, the distribution of mercury inside the lamp tubewill become unequally or will deplete the Ar gas in it. Then it may cause the abnormal phenomenon of lighting-up. Therefore, designers have to try their best to for fill the conditions under the inverter designing-stage as below: The degrees of unbalance: less than 10% The ratio of wave height: less than 2 10%
