A novel display device where a light-emitting element is turned on by a triangle wave is provided. One embodiment of the present invention is a method for driving a display device including a first pixel, a second pixel, a first wiring, a second wiring, and a third wiring. The first wiring is electrically connected to the first pixel and the second pixel. The second wiring and the third wiring are electrically connected to the first pixel and the second pixel, respectively. At a first time, the first pixel reaches the maximum luminance corresponding to first display data and the second pixel reaches the maximum luminance corresponding to second display data. The first pixel and the second pixel are initialized at a second time different from the first time by input of a reset signal to the first wiring to stop light emission.

An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To mitigate diffraction artifacts, a first sensor (13-1) may sense light through a first pixel removal region having transparent windows arranged according to a first pattern. A second sensor (13-2) may sense light through a second pixel removal region having transparent windows arranged according to a second pattern that is different than the first pattern. The first and second patterns of the transparent windows may result in the first and second sensors having different diffraction artifacts. Therefore, an image from the first sensor may be corrected for diffraction artifacts based on an image from the second sensor.

A display panel includes a first display region with multiple light-transmitting sub-pixels and multiple non-light-transmitting sub-pixels. The multiple light-transmitting sub-pixels and the multiple non-light-transmitting sub-pixels are arranged in a preset pixel arrangement structure in the first display region. The multiple non-light-transmitting sub-pixels are randomly arranged in at least one set region of the first display region.

A mobile computing device an emissive display that includes a touchscreen and a proximity sensor. The proximity sensor includes a transmitter configured to transmit electromagnetic radiation through the display and a receiver of electromagnetic radiation configured to receive electromagnetic radiation transmitted by the transmitter, reflected off an object facing the emissive display and received through the emissive display. The proximity sensor is configured for generating a quantitative output signal based on an amount of the received electromagnetic radiation, and the transmitter is configured to transmit a first predetermined amount of light when a distance between the object and the display is greater than a near threshold distance between the object and the display and is configured to transmit a second predetermined amount of light when the distance between the object and the display is less than the near threshold distance. The second predetermined amount is greater than the first predetermined amount. A processor is configured for receiving the generated quantitative output signal, and memory stores instructions that, when executed by the processor, cause the processor to deactivate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is activated and when the quantitative output signal increases above an high threshold value and to activate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is deactivated and when the quantitative output signal is below a low threshold value, the low threshold value being less than the high threshold value.
