1. OVERVIEW
CLAA181XA01 is 18.1” color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module
composed of LCD panel, driver ICs, control circuit and backlight.
By applying 8 bit digital data, 1024×768, 16.7M-color images are displayed on the 18.1” 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:

[Note 1]
Lamp Current measurement method ( The current meter is inserted in cold line)
[Note 2]
Lamp frequency of inverter may produce interference with horizontal synchronous
frequency,and this may cause horizontal beat on the display.Therefore,please adjust
lamp frequency,and keep inverter as far from module as possible or use electronic
shielding between inverter and module to avoid the interference.
