3-3. Signal Timing Specifications
This is the signal timing required at the input of the User connector. All of the interface signal timing should be
satisfied with the following specifications for it’s proper operation.
Note:
Table 6. Timing Table
Hsync period and Hsync width-active should be even number times of t
If the value is odd number times of t
In order to operate this LCM a Hsync, Vsync and DE (Data Enable) signals should be used.
1. The performance of the electro-optical characteristics may be influenced by variance of the vertical
2. Vsync, Hsync should be keep the above specification.
3. Hsync Period, Hsync Width and Horizontal Back Porch should be any times of a character number (8).
