Problems solved by technology

[0003] In the design of the existing QD-OLED display panel, due to the low conversion efficiency of QD (quantum dots) and the low efficiency of the blue light-emitting layer, the current efficiency of the final red pixel and green pixel is low, and the blue pixel needs to pass through Scattering particle layer and blue color film, the final current efficiency of blue pixels is also low, low pixel current efficiency will result in high final pixel current, resulting in large overall current of the display panel, increased driving voltage, and increased power consumption

Embodiment 1

[0066] Please combine figure 1 with figure 2 To understand, this embodiment provides a display substrate 1 and a display panel including the same.

[0067]The display substrate 1 includes a display structure layer 10, a cover plate 20 located on the display structure layer 10, and a plurality of pixel definition layers 30 and an anti-light interference layer 40 located between the display structure layer 10 and the cover plate 20, a plurality of The pixel definition layer 30 is arranged at intervals on the lower surface of the cover plate 20, and corresponds to the sub-pixel units of the display substrate 1 one by one, and the anti-light interference layer 40 is arranged around each pixel definition layer 30, wherein the anti-light interference layer 40 and the display A reflective component 50 is further provided between the structural layers 10 . The reflective component 50 has an inclined surface 51 for reflecting light from the display structural layer 10 incident on the...

Embodiment 2

[0084] Please combine image 3 with Figure 4 It is to be understood that the overall structure of the filtering device of this embodiment is basically the same as that of Embodiment 1, the difference is that the reflective member 50 includes a reflective layer 52 and an inclined layer 53, and the inclined layer 53 is located on the anti-light interference layer 40 Between the reflective layer 52 and the thickness of the inclined layer 53 gradually increases from the end close to the display structure layer 10 to the end far away from the display structure layer 10, and the lower surface of the inclined layer 53 forms an included angle with the plane where the light cross-talking layer 40 is located. θ, the reflective layer 52 covers the lower surface of the inclined layer 53 , so that the side of the reflective layer 52 close to the display structure layer 10 forms the inclined surface 52 . In this way, by disposing the reflective layer 52 on the lower surface of the incline...

Abstract

The invention provides a display substrate and a display panel comprising the same. The display substrate comprises a display structure layer, a cover plate located on the display structure layer, a plurality of pixel definition layers located between the display structure layer and the cover plate, and a light crosstalk prevention layer. The plurality of pixel definition layers are arranged on the lower surface of the cover plate at intervals, a light crosstalk prevention layer is arranged around each pixel definition layer, a reflection part is further arranged between the light crosstalk prevention layer and the display structure layer, the reflection part is provided with an inclined plane, and the inclined plane is used for reflecting light rays of the display structure layer to enterthe pixel definition layers. The reflection part is provided with the inclined plane, so the light emitted by the display structure layer originally absorbed by the light crosstalk prevention layer can be reflected; after the light is reflected to the display structure layer, the light is reflected to the pixel definition layer through the display structure layer, and therefore, the utilization efficiency of the light emitted by the display structure layer can be greatly improved, and the overall current efficiency is greatly improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display substrate and a display panel comprising the same. Background technique [0002] At present, the technologies under development for large-scale display products mainly include QD-OLED, IJP OLED, QDCF-LCD and other technologies. Among them, QD-OLED has high resolution, high color gamut, and no viewing angle dependence. It can be applied to large and medium-sized high Color gamut in high-resolution products. [0003] In the design of the existing QD-OLED display panel, due to the low conversion efficiency of QD (quantum dots) and the low efficiency of the blue light-emitting layer, the current efficiency of the final red pixel and green pixel is low, and the blue pixel needs to pass through Scattering particle layer and blue color film, the final current efficiency of blue pixels is also low, low pixel current efficiency will lead to high final pixel current, ...
