Abstract

The invention aims to provide a display panel and a preparation method thereof and a display device. The display panel comprises: a display substrate, wherein the display substrate comprises a plurality of pixel units, and each pixel unit is provided with a light emitting side; and a light distribution layer arranged on the display substrate and located on the light emitting sides of the pixel units, wherein the light distribution layer comprises a plurality of lenses, the lenses correspond to the pixel units, and the orthographic projection area of each lens on the display substrate is smaller than the area of the corresponding pixel unit. According to the display panel, the light distribution layer is additionally arranged on the light emitting side of the display substrate, and the technical scheme that the micro lens is achieved through the photoetching method is adopted, so that the requirement for mass production can be met, and the visual angle, the brightness, the color cast and the like of the display panel can be effectively improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device using the display panel. Background technique [0002] OLED display panel (Organic Light Emitting Display) has self-illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, and relatively simple structure and manufacturing process And other excellent characteristics, it is considered to be an emerging application technology of the next generation of flat panel display devices. But it also has some defects of its own. On the one hand, the brightness of OLED is low, and its stability is slightly worse than other displays; It is because of the microcavity effect of the R / G / B pixel light-emitting device in the inkjet printed OLED display panel. [0003] In order to improve the viewing angle and...
