1. OVERVIEW
T-51638D084-FW-A-AA is 8.4” 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 digital data, 640
´
480, 262,144-color images are displayed on the 8.4” diagonal
screen. Input power voltage is single 3.3V for LCD driving.
Inverter for backlight is not included in this module. General specifications are summarized in
the following table:

*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.
