Problems solved by technology

When the OLED device emits light, there is light leakage from adjacent pixels, resulting in color deviation on the pixel display, resulting in color shift
During the alignment process of the cover plate and the display substrate, there is often a slight deviation in the alignment of the package, or the product design requires a slight deviation in the alignment of the cover plate and the display substrate, which makes the color shift more serious

[0082] Based on the inventive concepts of the foregoing embodiments, the embodiments of the present invention further provide a display panel. Such as Figure 4 As shown, the display panel includes the display substrate 100 in the above embodiments, and also includes a cover plate 200 . The cover plate 200 and the display substrate 100 are arranged in opposition, and an isolation column 300 is disposed between the cover plate 200 and the display substrate 100 . The cover plate 200 includes a second base (not shown in the figure), and a color filter layer 21 disposed on a side of the second base facing the display substrate. The color filter layer 21 includes a red color filter (R), a green color filter (G) and a blue color filter (B) corresponding to the light-emitting areas, so as to form pixels corresponding to the light-emitting areas on the display panel. The red pixels are located on the red color film (R), the green pixels are located on the green color film (G), and t...

Abstract

The invention discloses a display substrate, a preparation method thereof, and a display panel. The display substrate includes a base and a plurality of OLED devices arranged on the base, and also includes a thin-film encapsulation layer arranged on the OLED devices and a light-blocking layer arranged on the thin-film encapsulation layer and located between two adjacent OLED devices. Floor. The display panel includes the display substrate and a cover plate arranged opposite to the display substrate, the cover plate includes a color filter layer, and the color filter layer has a red color filter and a green color filter corresponding to the OLED device. and blue color film. The light-blocking layer can function as a black matrix, so that the black matrix does not need to be arranged on the cover plate, which simplifies the manufacturing process of the cover plate. Compared with the black matrix set on the cover plate, the light blocking layer is closer to the OLED device, so that the light leakage angle of the light emitted by the OLED device irradiating the adjacent pixels is greatly reduced, and the color deviation of the pixel is reduced, so that the pixel display Colors are purer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display panel. Background technique [0002] Currently, display devices are appearing in the display market and the daily life of the general public in increasingly diverse and novel forms. Display devices include liquid crystal display (LCD), which is already quite mature in technology and is developing towards ultra-high resolution, small and medium-sized organic light-emitting diode (OLED) display devices that are widely used in portable devices such as mobile phones and Pads, and increasingly mature TV display devices. large-scale organic light-emitting diode (OLED) display devices. At the same time, with the development of the information society, novel display technologies such as transparent display devices have obtained good user experience and have broad market prospects. [0003] In display devices, the top emi...
