DISPLAY METHOD FOR SUNLIGHT READABLE AND ELECTRONIC DEVICE USING THE SAME

A display method for sunlight readable is provided, which is applicable to an electronic device having a display panel. The display method includes the following steps. An ambient light sensor value and image content are obtained. Next, a liquid crystal (LC) driving voltage is altered based on the ambient light sensor value and the image content, wherein the LC driving voltage is increasingly proportional to the ambient light sensor value and exceeds a normal operation driving voltage when the ambient light sensor value exceeds a high luminance value. Then, the display panel is drived under the LC driving voltage. Finally, a sunlight readable image is displayed on the display panel.
