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 Width, and Horizontal Back Porch should be any times of of character
number(8).
4. The polarity of Hsync, Vsync is not restricted.
