Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Note that embodiments may be implemented in many different forms. Those skilled in the art can easily understand the fact that the manner and content can be changed into various forms without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure should not be construed as being limited only to the contents described in the following embodiments. The embodiments of the present disclosure and the features of the embodiments may be arbitrarily combined with each other without conflict.

[0030] In the drawings, the size of each constituent element, the thickness of a layer, or a region are sometimes exaggerated for clarity. Therefore, one form of the present disclosure is not necessarily limited to this size,...

Abstract

The embodiment of the invention provides a display panel, a preparation method thereof and a display device. The overall light emitting efficiency of an OLED (Organic Light Emitting Diode) can be improved. The display panel comprises a substrate, a display structure layer arranged on the substrate and an anti-dazzle layer arranged on the side, away from the substrate, of the display structure layer, the display structure layer comprises a light-emitting area and a non-light-emitting area, and the anti-dazzle layer comprises a light-transmitting layer and a protruding structure layer. The protruding structure layer is located on the side, away from the substrate, of the light transmitting layer, the protruding structure layer comprises protrusions facing the substrate, and the orthographic projection of the protrusions on the substrate and the orthographic projection of a non-light-emitting area of the display structure layer on the substrate are at least partially overlapped; and the refractive index of the light-transmitting layer is higher than that of the convex structure layer. By sacrificing side-view-angle light emitting, the front-view-angle light emitting gain is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to, but are not limited to, the field of display technology, and more particularly, to a display panel, a method for manufacturing the same, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is an active light-emitting display device, which has the advantages of self-luminescence, wide viewing angle, high contrast ratio, low power consumption, extremely high response speed, thinness, flexibility and low cost. With the continuous development of display technology, a flexible display device (Flexible Display) that uses OLED as a light-emitting device and is signal-controlled by a Thin Film Transistor (TFT) has become a mainstream product in the current display field. [0003] However, the overall light extraction efficiency of the OLED in the related art is low. SUMMARY OF THE INVENTION [0004] The following is an overview of the topics detailed in this article. T...
