TRANSREFLECTIVE DISPLAY APPARATUS AND DRIVING METHOD THEREOF
First Claim
1. A driving method for a transreflective display apparatus, the driving method comprising:
- providing a plurality of voltage-to-transparency (V-T) curves;
detecting an ambient light intensity of the display apparatus;
determining a display mode according to the ambient light intensity, wherein the display mode is either a transmissive mode or a reflective mode; and
selecting one of the V-T curves to drive the display apparatus based on the display mode and the ambient light intensity.

Abstract
A driving method and a transreflective display apparatus are provided herein. In the driving method, a plurality of voltage-to-transparency curves are provided. An ambient light intensity of the display apparatus is detected for determining a display mode, wherein the display mode is either a transmissive mode or a reflective mode. Next, one of the voltage-to-transparency curves is selected according to the display mode and the ambient light intensity for driving the display apparatus. Therefore, by referring a proper voltage-to-transparency curve to drive the display apparatus, the display quality of the display apparatus can be enhanced.
