2. OVERVIEW
T-55708D121J-LW-A-AAN is 12.1” color TFT-LCD (Thin Film Transistor Liquid Crystal Display)
module composed of LCD panel, driver ICs, control circuit, LED driver and backlight unit.
By applying 6 bit or 8 bit digital data, 800 × 600, 262k-color or 16.7M-color images are displayed on
the 12.1” diagonal screen. Input power voltages are 3.3 V for LCD driving and 12.0 V for backlight
unit.
The type of data and control signals are digital and transmitted via LVDS interface per Typ. 40
MHz clock cycle.
General specifications are summarized in the following table:
