Abstract

A display method is suitable for a display device. A display panel of a display device includes a plurality of pixel circuits. A first pixel circuit of the plurality of pixel circuits is over the ambient light sensor. The display method comprises the following steps: controlling a first pixel circuit to enable the first pixel circuit not to shine in a first time interval in an updating time interval of the first pixel circuit; controlling the ambient light sensor to perform light sensing in a first time interval of the first pixel circuit to obtain ambient light intensity; and adjusting the display brightness of the display panel according to the ambient light intensity.

Description

technical field [0001] The present disclosure relates to a display device, in particular to a display device in which an ambient light sensor is disposed in a display area of ​​a display panel. Background technique [0002] In the prior art, in the application of electronic products, an ambient light sensor (ALS) is integrated in a non-display area outside the panel to sense the ambient illuminance. However, if the ambient light sensor can be arranged behind the display area of ​​the display panel, the screen-to-body ratio of the display can be greatly increased. Contents of the invention [0003] An embodiment of the present disclosure is to provide a display device. The display device includes a display panel, an ambient light sensor and a processor. A display panel includes a plurality of pixel circuits. A first pixel circuit among the plurality of pixel circuits includes a first light emitting diode. The first light emitting diode is not turned on during the first ...
