2. OVERVIEW
AA121TD11 is 12.1” color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module
composed of LCD panel, driver ICs, control circuit and backlight unit.
By applying 6 bit or 8 bit digital data, 1280u 800, 262k-color or 16.7M-color images are displayed
on the 12.1” diagonal screen. Input power voltage is single 3.3 V for LCD driving.
The type of data and control signals are digital and transmitted via LVDS interface per Typ. 71
MHz clock cycle.
Driver circuit for LED backlight is not included in this module. General specifications are
summarized in the following table:
