Notes: Hsync period and Hsync width-active should be even number times of tCLK. If the value is odd number

times of tCLK, display control signal can be asynchronous. In order to operate this LCM a Hsync,

Vsyn, and DE(data enable) signals should be used.

1. The performance of the electro-optical characteristics may be influenced by variance of the vertical

refresh rates.

2. Vsync and Hsync should be keep the above specification.

3. Hsync Period, Hsync W idth, and Horizontal Back Porch should be any times of character

number(8).

4. The polarity of Hsync, Vsync is not restricted.

3-3. Signal Timing Specifications

Table 6. Timing Table

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.
