Problems solved by technology

In order to achieve a full screen, the existing OLED display device will set the camera under the display panel, so that when the camera function is realized, the display function is turned off, and when the display function is realized, the camera area under the screen is displayed, that is, CUP (Camera Under Panel , under-screen camera) technology, but for OLED display panels with under-screen cameras, in the light-emitting area above the projection of the camera, the external light passes through the cathode, and the light intensity will be lost by about 50%, and the light loss of the cathode will be directly Affects the photo effect, so it is necessary to improve the cathode structure in this area to increase the light transmittance
However, the current display panel is prone to the problem that the camera area under the screen is brighter than the display area under large viewing angles.

Abstract

The invention discloses a display panel, the display panel comprises a first display area and a second display area, the first display area surrounds at least one part of the second display area, the display panel comprises a substrate, a light emitting layer and an optical structure layer, the light emitting layer is arranged on the substrate, the light emitting layer comprises a plurality of first sub-pixels and a plurality of second sub-pixels, the first sub-pixels correspond to the first display area, the second sub-pixels correspond to the second display area, the optical structure layer is arranged on the side, away from the substrate, of the light emitting layer, and the light gathering capacity of the optical structure layer corresponding to the first display area is smaller than that of the optical structure layer corresponding to the second display area.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED) panels have self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display With many advantages such as large-area full-color display, it is recognized by the industry as the next-generation flat-panel display emerging application technology. [0003] At present, top-emission structure OLED display panels are commonly used, but most of the current products use a cathode structure of magnesium, silver alloy or laminated structure. Magnesium and silver metals have low work function to ensure electron output efficiency; With a certain reflection effect, it forms a resonant cavity with the anode to ensure that the light emitted from the lig...
