Abstract
A method for adjusting ambient contrast ratio and an electronic apparatus are provided. The electronic apparatus includes a transparent display and a transmittance adjustment plate disposed at the back of the transparent display. In the electronic apparatus, an adjustment transmittance used to adjust the transmittance adjustment plate and a luminance percentage used to adjust the transparent display are calculated, a grayscale layer is generated based on the luminance percentage; a voltage generator is used to control the transmittance of the transmittance adjustment plate to the adjustment transmittance, and in a case that the transmittance of the transmittance adjustment plate is the adjustment transmittance, a graphic controller is used to display a frame on the transparent display while display the grayscale layer on top of the frame.
