2.0 General Description
This specification applies to the 12.1 inch wide Color TFT/LCD Module A121EW01 V0
This module is designed for a display unit of Portable Video Devices.
The screen format is intended to support the XGA (1280(H) x 800(V)) screen and 262k colors (RGB 6-bits data
driver).
All input signals are LVDS interface compatible.
This module does not contain an inverter card for backlight.

Note 5
Note 1: DP-1 are AUO recommended Design Points.
*1 All of characteristics listed are measured under the condition using the AUO Test inverter.
*2 In case of using an inverter other than listed, it is recommended to check the inverter carefully. Sometimes,
interfering noise stripes appear on the screen, and substandard luminance or flicker at low power may happen.
*3 In designing an inverter, it is suggested to check safety circuit ver carefully. Impedance of CCFL, for instance,
becomes more than 1 [M ohm] when CCFL is damaged.
*4 Generally, CCFL has some amount of delay time after applying start-up voltage. It is recommended to keep
on applying start-up voltage for 1 [Sec] until discharge.
