Abstract

The invention provides a diffraction-suppressing display screen, comprising at least part of a light-transmitting display area, including periodically arranged pixel units in the light-transmitting display area, and conductive grid lines defining the pixel units; the conductive grid lines include light-tight main Grid line grids, each main grid line grid defines a pixel unit array including at least two pixel units; and transparent sub-grid line grids arranged periodically in each main grid line grid, each sub-grid line grid A grid defines a pixel unit. The present invention also provides a mobile terminal device comprising the diffraction-suppressed display screen. The technical solution of the present invention does not affect the function of the display unit. By increasing the period of the opaque grating lines, transparent grating lines are used within the period of the opaque grating lines to reduce the diffraction caused by the periodic arrangement of small-sized opaque grating lines. Effect, weaken the resulting starburst effect, improve the imaging quality of the imaging unit for the transmitted light, or the projection effect of the projection unit.

Description

technical field [0001] The present invention relates to a diffraction-suppressed display screen, and more particularly, to a diffraction-suppressed display screen for eliminating or suppressing diffraction phenomena. The invention also relates to a mobile terminal device comprising a diffraction-suppressed display screen. Background technique [0002] The popularity and convenience of flat panel display products in consumer electronics applications is increasing. With the development of the concept and technology of smart terminals, the integrated functions undertaken by smart terminals also need to carry signal output / input functions within the limited size range / weight range of the display screen of flat panel display products, such as display, imaging, projection , detection, etc. [0003] In existing products, the display unit and other optical modules (camera, 3D structured light projection module, etc.) are usually arranged separately on the plane layout, and the pix...
