Problems solved by technology

[0002] Organic Light-Emitting Diode (OLED) display panels have the advantages of high color gamut, good viewing angle, fast response time, etc., but they also have some defects of their own, such as low brightness of OLED display panels, relatively stable Slightly worse than other monitors
On the other hand, for OLED devices made by inkjet printing technology (IJP), there is also a risk of angular misalignment, because of the microcavity effect of IJP OLED sub-pixel light-emitting devices
[0003] In order to improve the viewing angle and brightness of OLED display panels, many methods have been proposed, such as adding optical microstructures (microlens arrays and gratings, etc.) on the exit surface of the display panel, or adding a refractive index matching layer between the light exit interfaces, etc., Although these methods have certain effects, the feasibility of mass production is not high

Abstract

The invention provides a display panel comprising an array substrate, an OLED functional layer, a packaging layer, a filling layer, a protective layer, an edge packaging adhesive and nanoparticles; the nanoparticles are uniformly arranged in the filling layer or the protective layer of the panel, and the nanoparticles can effectively improve the light diffusion effect, so that the visual angle ofthe display panel can be effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels have the advantages of high color gamut, good viewing angle, fast response time, etc., but they also have some defects of their own, such as low brightness of OLED display panels, relatively stable Slightly worse than other monitors. On the other hand, for OLED devices made by inkjet printing technology (IJP), there is also a risk of angular misalignment because of the microcavity effect of IJP OLED sub-pixel light-emitting devices. [0003] In order to improve the viewing angle and brightness of OLED display panels, many methods have been proposed, such as adding optical microstructures (microlens arrays and gratings, etc.) on the exit surface of the display panel, or adding a refractive index matching layer between the light e...
