Embodiment Construction

[0049]As mentioned in the background, in the silicon-based micro-OLED display panel, since the cathode is a whole-surface structure, a short circuit occurs inside individual sub-pixels, which will affect the display effect of other sub-pixels. It can be seen that it is very important to achieve independent control of sub-pixels.

[0050] In order to realize the independent control of sub-pixels, based on the glass-based display panel in the related art, it is proposed to realize the division of the cathode through the process of making PS (Post Spacer, spacer) retaining wall on the glass substrate. The defects of this technology are: 1. The PS wall will increase the thickness of the entire display module; 2. The PS wall process requires very strict conditions, such as strict control of exposure time and exposure dose; 3. Limited by the glass-based process, the block size of cathode division is strictly controlled At the same time, a large number of cathode voltage signal lines...

Abstract

The disclosure provides a display panel, a manufacturing method thereof and a display device, and the invention is used for solving the problem that the display effect of other sub-pixels is influenced by the short circuit generated inside an individual sub-pixel. Wherein, the manufacturing method of the display panel comprises the following steps of manufacturing a plurality of anodes on a substrate; manufacturing a photoresist layer on a gap area among the anodes, wherein the photoresist layer defines a plurality of partition areas, and each partition area defined by the photoresist layer isused for accommodating at least one anode, a light emitting layer to be formed and a cathode layer to be formed; and sequentially manufacturing a light emitting layer and a cathode layer on one sideof the plurality of anodes and the photoresist layer which is opposite to the substrate. The manufacturing method is applied to manufacturing of the display panel, and the independence of the cathodesof the sub-pixels can be improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, with the increasing progress of VR (Virtual Reality, virtual reality) / AR (Augmented Reality, augmented reality) technology and the rapid growth of the market, display panels suitable for VR / AR fields are also rapidly becoming miniaturized, high PPI ( Pixels Per Inch, the number of pixels per inch), fast response and high color gamut, silicon-based display panels, especially silicon-based micro OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panels are the most prominent one direction. Although silicon-based micro-OLED technology started late, it is becoming a new focus in the display field due to its advantages of miniaturization and high PPI. [0003] For a silicon-based micro OLED display panel, its PPI is high, which means t...
