DISPLAY PANEL, DISPLAY SCREEN, AND DISPLAY TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/052232
Kind Code:
A1
Abstract:
The present application provides a display panel, comprising a substrate and multiple film layers which are provided on the substrate in sequence, at least one of the film layers having a patterning structure. The display panel has m light-transmissive paths, m being an integer greater than or equal to 2; the paths are light-transmissive paths vertical to the surface of the substrate, wherein film layers comprised in a first path and a second path are different; when the thickness of the film layer is set as a preset thickness, and the refractive index is set as a preset refractive index, external incident light is incident on the display panel in a direction vertical to the surface of the substrate, and after the light passes through the first path and the second path, an optical path difference between the two paths is an integral multiple of the wavelength of the external incident light. According to the present solution, because the difference between the two paths is an integral multiple of the wavelength of the incident light, after the light is emitted from the display panel through the two paths, the phase difference therebetween is zero, a diffraction phenomenon caused by the phase difference is canceled, so that after light passes through the display panel, no image distortion caused by diffraction would be produced, and the definition of image sensing by a camera at the rear of the display panel is improved.
