no. 1 example

[0025] The invention provides a display substrate.

[0026] like figure 1 As shown, in one embodiment, the display substrate includes a base substrate 101 and an anti-peep layer 102 disposed on the base substrate 101 , and the base substrate 101 has a plurality of pixel regions.

[0027] like figure 2 As shown, the anti-peeping layer 102 includes a light propagation layer 1021 and a plurality of directional gratings 1022 , and one directional grating 1022 corresponds to at least one pixel region on the base substrate 101 .

[0028] The directional grating 1022 in this embodiment is used to direct the light that enters the light propagation layer 1021 out. It can only shoot in a specific direction. In this way, only in the outgoing direction of the light, the content displayed on the screen can be observed, and in other directions, the content displayed on the screen cannot be observed, thereby achieving the effect of anti-peeping.

[0029] The anti-peeping layer 102 may c...

[0064] The present invention also provides a method for preparing a display substrate, which is used for preparing any one of the display substrates in the above embodiments.

[0065] In one embodiment, the method comprises the steps of:

[0066] providing a base substrate 101, and forming an anti-peeping layer 102 on the base substrate 101;

[0067] Wherein, the base substrate 101 has a plurality of pixel regions, the anti-peeping layer 102 includes a light propagation layer 1021 and a plurality of directional gratings 1022, and the directional gratings 1022 are used to direct the light entering the light propagation layer 1021 The light is oriented and emitted, and one directional grating 1022 corresponds to at least one pixel area on the base substrate 101 .

[0068] The base substrate 101 in this embodiment may refer to the base substrate 101 in the existing display substrate, and the anti-peeping layer 102 formed may also refer to the anti-peeping layer 102 in the above-...

Abstract

The present invention provides a display substrate and a display device, wherein the display substrate includes a base substrate and a peep-proof layer disposed on the base substrate, the base substrate has a plurality of pixel regions, and the peep-proof layer It includes a light propagation layer and a plurality of directional gratings, and the directional gratings are used to orientate and emit light entering the light propagation layer, and one directional grating corresponds to at least one pixel area on the base substrate. In the present invention, by setting the directional grating, the light can be emitted along a specific direction, so as to achieve the anti-peeping effect. At the same time, because the anti-peeping layer is arranged on the base substrate, it is also convenient to adjust the display brightness when correcting the display substrate. , which can avoid the decrease in image brightness observed by the user.

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 device. Background technique [0002] With the development of society and the improvement of people's living standards, a wide variety of electronic devices such as mobile phones, computers, and televisions are more and more closely related to people's life and work, but electronic devices are providing people with more and more convenience. At the same time, it may also lead to the leakage of personal information. [0003] In order to protect the privacy of the user and realize the anti-peep display on the screen, the existing anti-peep method is generally to attach a layer of anti-peep film on the display screen, but this kind of anti-peep film attenuates the light to a high degree, and the user can see through the anti-peep The image screen observed by the membrane will be relatively dim.
