Compensation for displays, under-display optics and electronics

Abstract

A compensating display screen, an optical system, and an electronic device are provided. The compensating display screen includes: a transparent display screen, comprising a plurality of periodically arranged pixel units for display; and a compensating element, configured to compensate a diffraction effect of the transparent display screen, so that when a preset light beam is incident on the compensating display screen, the same preset light beam is emitted from the compensating display screen. An optical system, comprises the above compensating display screen, and an optical module configured to receive a light beam from the transparent display screen or emit a light beam outward through the transparent display screen. An electronic device, comprises the above optical system, and a filter unit disposed between the transparent display screen and the optical module, and configured to reduce passage of visible light from the transparent display screen.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a compensation display screen, an optical system under the screen and electronic equipment. Background technique [0002] Taking photos and displaying is an essential function of many electronic devices at present. Front cameras and displays are installed on the front of electronic devices to meet various needs, such as Selfie, content display, touch interaction, etc. [0003] As people have higher and higher requirements for the aesthetics of mobile phones, full-screen electronic devices, such as full-screen mobile phones, have gradually become a new direction for mobile phone innovation, because full-screen mobile phones have a very high screen-to-body ratio, are easy to control, and are very aesthetically pleasing visual impact. The challenge faced by current full-screen electronic devices is the conflict between the front camera and the display screen. The ex...

Problems solved by technology

The challenge faced by current full-screen electronic devices is the conflict between the front camera and the display screen. The existence of the front camera makes it difficult for the display screen to fill the entire front of the phone in a true sense in order to achieve a higher screen-to-body ratio.

[0004] Setting the optical module on the back of the display screen can realize a full screen, and the display screen is located in the front for displaying the picture. The light received or emitted by the optical module will pass through the display screen, but since the display screen is composed of multiple horizontal and vertical Multiple pixel units form a periodic pixel diffraction structure, so the display screen will have a diffraction effect on the incident light beam, which will eventually lead to a decrease in the projection or imaging quality of the optical module set on the back of the display screen
