A display includes a camera under panel, a display panel, a frame rate controller, and a switching circuit. The display panel includes an under-panel camera region corresponding to the camera under-panel. A first pixel set, positioned in the under-panel camera region, driven by a first scan line, a second scan line, a first data line, a second data line, a third data line, and a fourth data line. The first pixel set includes a first pixel electrically connected to the first scan line and the third data line, a second pixel electrically connected to the second scan line and the third data line, a third pixel electrically connected to the first scan line and the first data line, a fourth pixel electrically connected to the second scan line and the second data line, and a fifth pixel electrically connected to the second scan line and the fourth data line.

Display and driving method

A display device and an electronic apparatus both include a display part and a camera part. The display part has a first display region and a second display region. The first display region is around the second display region. A pixel density of the second display region is less than a pixel density of the first display region, wherein a plurality of first sub-pixels within the first display region are configured into a red-green-blue-green array, and a plurality of second sub-pixels within the second display region are configured into a red-green-blue array. The camera part is disposed at a position corresponding to the second display region on a side of the display part. Thus, it can solve a problem of complex panel opening and assembly in the prior art.

Display device and electronic apparatus

The present invention relates to a display panel, an electronic device, and an operation method of the electronic device. The display panel is divided into a display region and a plurality of image capturing regions.
