Problems solved by technology
Due to the OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology has a wider viewing angle, OLED phones are easy to be peeped by others
[0003] The commonly used method in the prior art is to paste a privacy film on the surface of the mobile phone screen, but the privacy film reduces the brightness of the side of the device and also causes a certain degree of loss to the front brightness, resulting in an increase in the power consumption of the mobile phone

The embodiment of the invention provides a display substrate, a display screen and a display device. The display substrate comprises a substrate body, a first electrode layer, a pixel definition layer, an angle adjusting structure and a peep-proof structure, wherein the substrate comprises a plurality of light-emitting areas and dark areas located between the adjacent light-emitting areas; the pixel definition layer is provided with a plurality of openings, and the orthographic projection of each opening on the substrate coincides with one light-emitting area; the angle adjusting structure islocated on the side, away from the substrate, of the pixel defining layer, the orthographic projection of the angle adjusting structure on the substrate is located in the dark area, and the angle adjusting structure enables light, exceeding a display view angle, emitted by the adjacent light-emitting areas to be emitted to the peep-proof structure; and the peep-proof structure covers the side faceof one angle adjusting structure, light emitted to the peep-proof structure is absorbed by the peep-proof structure, or the light emitted to the peep-proof structure is subjected to diffuse reflection by the peep-proof structure, and therefore, the situation that the light exceeding the display visual angle is emitted out of the display substrate is reduced. The display substrate disclosed by oneembodiment of the invention has the same effect of a peep-proof screen and does not influence the brightness of front display.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display substrate, a display panel and a display device. Background technique [0002] Out of consideration for privacy issues, users hope that when they use their mobile phones, the content they watch will not be seen by others. Because OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology has a wider viewing angle, OLED mobile phones are easy to be peeped by others. [0003] The common method in the prior art is to paste a privacy film on the surface of the mobile phone screen, but the privacy film reduces the brightness of the side of the device and also causes a certain degree of loss of the front brightness, resulting in increased power consumption of the mobile phone. Contents of the invention [0004] In view of the shortcomings of the existing methods, the present application proposes a di...
