Display substrate, display panel and display device

Abstract

The invention provides a display substrate, a display panel and a display device. The display substrate comprises a display area and a frame area at least partially surrounding the display area, the display area comprises a first display area and a second display area, and the light transmittance of the first display area is greater than that of the second display area; a plurality of pixel groupsarranged in the first direction are arranged in the display area, and each pixel group comprises a first sub-pixel group and a second sub-pixel group, or each pixel group only comprises a second sub-pixel group; the first sub-pixel group comprises at least one first sub-pixel, the second sub-pixel group comprises at least one second sub-pixel, and when the number of the sub-pixels in the same pixel group is more than one, the plurality of sub-pixels are arranged at intervals along a second direction; the display area is internally provided with a pixel circuit for driving sub-pixels, the frame area is internally provided with m EM signal control circuits, m is an integer greater than 2, each EM signal control circuit comprises a plurality of output terminals, and each output terminal iselectrically connected with the pixel circuits of at least part of the sub-pixels in one pixel group.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display substrate, a display panel and a display device. Background technique [0002] With the rapid development of electronic devices, users have higher and higher requirements for screen-to-body ratio, so that the full-screen display of electronic devices has attracted more and more attention from the industry. Traditional electronic devices such as mobile phones, tablet computers, etc., need to integrate such as front camera, earpiece, and infrared sensing components, so it is possible to set the camera, earpiece, and infrared sensing elements in the slotted area by slotting (Notch) on the display screen. Components, etc., but the slotted area cannot be used to display the picture, such as the notch screen in the prior art, or the method of opening holes on the screen. For electronic equipment that realizes the camera function, external light can pass through the...
