Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0026] Due to the microcavity effect between the anode and cathode of the OLED device, there will be brightness attenuation and color shift under large viewing angles.

[0027] In order to solve the above problems, an embodiment of the present invention provides a display panel, by making the light-emitting film layer or the organic film layer located in the first pixel area, the second pixel area and the third pixel area have protrusions with different radians, so that The convex part can make the exit angle and ...

Abstract

The embodiment of the invention discloses a display panel and a manufacturing method thereof. The display panel comprises a substrate including a first pixel region, a second pixel region and a thirdpixel region; a first electrode layer disposed on the substrate; a light-emitting film layer disposed on the first electrode layer; a second electrode layer disposed on the light-emitting layer; an organic film layer disposed on the second electrode layer, wherein the light-emitting film layer or organic film layer located in the first pixel region, the second pixel region, and the third pixel region has convex portions with incompletely same curvature. The light-emitting film layer or the organic film layer has incompletely same convex portions corresponding to different pixel regions, so asto increase the extraction rate of light, improve the scattering degree of the emitted light, reduce the total reflection of light, and alleviate the large view angle color cast caused by a micro-cavity effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as a current-mode light-emitting device, is widely used in the field of high-performance display because of its characteristics of self-luminescence, fast response, wide viewing angle and can be fabricated on flexible substrates. middle. At present, due to the microcavity effect between the anode and the cathode of OLED devices, when people watch the screen at angles other than the viewing angle, they will find ghosting and discoloration of the image, which seriously affects the viewing effect. Contents of the invention [0003] In a first aspect, an embodiment of the present invention provides a display panel, which includes: [0004] A substrate, including a first pixel area, a second pixel area, and a third pixel area; a first ...
