Note:

•

When temperature is below 0°C, the response time of liquid crystal (LC) will be slower and the

color of panel will be darker.

•

If module driving condition exceeds the absolute maximum ratings, permanent damaged may be

resulted. If module is driven within the absolute maximum ratings but exceeded the DC

characteristics, mal-function may be resulted.
