The present disclosure is drawn to displays for electronic devices. In one example, the display includes a light emitting layer with an organic light emitting element. A porous substrate can be attached to the light emitting layer, wherein the porous substrate is flexible and spreads heat generated by the light emitting layer. A cover layer can be attached to a surface of the porous substrate opposite the light emitting layer.

A system that can intelligently help a user judge the resolution requirement of the image content. In an example, the display panel can show in different virtual resolutions or the system can automatically judge whether the image content requires high or low resolution using a similarity judgement. The system can then inform the display panel what virtual resolution should be shown or what the optimal resolution is using the similarity judgment and send the image content to the display panel with that resolution.

Resolution switching

In examples, an electronic device comprises a camera and a display having a transparent area aligned with the camera. The display comprises a first line corresponding to a pixel row or column of the display, the first line extending from a first end of the display to the transparent area.

The electronic device includes a controller coupled to the display, the controller to drive the first and second lines consecutively.
