2.2 Signal Characteristic
Pixel Format Image
Following figure shows the relationship of the input signals and LCD pixel format.

LITEMAX Electronics Inc. Page 9
2.3 The input data format
Note1: Normally DE mode only. VS andHS on EVEN channel are not used.
Note2: Please follow VESA.
Note3: 8-bits signal input.

LITEMAX Electronics Inc. Page 10
2.4 Signal Description
The module using a pair of LVDS receiver SN75LVDS82 / SN75LVDS83
(Texas Instruments) or compatible. LVDS is a differential signal technology for LCD interface and high
speeddata transfer device. Transmitter shall be SN75LVDS83(negative edge sampling) or compatible.
The first LVDS port(RxOxxx) transmits odd pixels while the secondLVDSport(RxExxx) transmits even
pixe

LITEMAX Electronics Inc. Page 11
Note1: Start fromleft side
Note2: Inputsignals of clock shall be the same timing.
Note3: Please follow TV VESAPin Assignment.

LITEMAX Electronics Inc. Page 12
2.5 Timing Characteristics
Note 1: Only DE mode operation.
The input of Hsync & Vsync signal does not have an effect upon the LCD normal operation.
Note 2: The performance of the electro-optical characteristics may be influenced by variance of the
vertical refresh rates.
Note 3: Horizontal period should be even.
