Title
(EN) DISPLAY STRUCTURE AND ELECTRONIC DEVICE
Abstract
(EN)

A display structure and an electronic device having the same are provided. The display structure includes a display screen and a light adjusting component located at a light emitting side of the display screen. An operating state of the light adjusting component comprises a light transmitting state and a polarization state, and the light adjusting component comprises a first region and a second region which are independently controllable. The display screen comprises a plurality of independently controllable pixels. Further, when the first region of the light adjusting component is in the light transmitting state, the pixels that are in the display screen and correspond to the first region are disabled to allow light emitted from the first region to penetrate through the display screen.
