Embodiment Construction
[0030] The invention provides a method for manufacturing a display substrate, which is used to solve the problem of uneven film thickness and uniformity difference between pixels when forming a display film layer in a pixel area by inkjet printing in the prior art.
[0031] The manufacturing method includes: manufacturing a first pixel partition wall to define a first pixel region, and manufacturing a second pixel partition wall to define a second pixel region, wherein the height of the first pixel partition wall is greater than the height of the second pixel partition wall, and Multiple adjacent second pixel regions are located in the same first pixel region. Therefore, when the same display material is inkjet printed in the first pixel area, the same display film layer can be formed in multiple second pixel areas in the first pixel area, and the height of the display film layer can be set greater than the height of the second pixel partition wall, that is, the display film l...

The invention relates to the field of display technology, and discloses a display substrate, a manufacturing method thereof, and a display device. The pixel partition wall of the display substrate includes a first pixel partition wall defining a first pixel area and a second pixel partition wall defining a second pixel area. Wherein, the height of the first pixel partition wall is greater than the height of the second pixel partition wall, and a plurality of adjacent second pixel regions are located in the same first pixel region, so that inkjet printing of the same display in the first pixel region material, the same display film layer can be formed in multiple second pixel regions in the first pixel region, and the height of the display film layer is set to be greater than the height of the second pixel partition wall, that is, the first The display film layer in the pixel area is connected, and the corresponding pixel film layer is printed in the first pixel area by short-side printing, which ensures that the display film layer in the second pixel area has the same film thickness and improves the quality of the display substrate , which improves the display quality.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Compared with liquid crystal displays, Organic Light-Emitting Diode (OLED) display devices have the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright colors, thin and light, etc., and are considered to be the next-generation display technology. [0003] The main structure of an OLED display device is an OLED display substrate, which includes a plurality of pixel regions defined by a pixel defining layer, and each pixel region includes an OLED that emits light of a specific color. In the manufacturing process of OLED display substrates, the film-forming methods for forming OLEDs mainly include evaporation process and solution process. The application of the evaporation process in small-sized display devices is relatively mature, and t...
