Abstract

A dual-view display substrate and a dual-view display device are provided. The dual-view display substrate includes a base substrate; first display areas and second display areas are alternately arranged and disposed on the base substrate; the first display areas and the second display areas are respectively provided with display units; main light-emitting directions of the display units of each first display area are consistent with each other and correspond to a first view region from which only the first display areas can be viewed; and main light-emitting directions of the display units of each second display area are consistent with each other and correspond to a second view region from which only the second display areas can be viewed.

First claim

The invention claimed is:

1. A dual-view display substrate, comprising a base substrate, first display areas and second display areas that are alternately arranged being disposed on the base substrate, the first display areas and the second display areas respectively being provided with display units, wherein
main light-emitting directions of the display units of each first display area are consistent with each other and correspond to a first view region from which only the first display areas can be viewed; and main light-emitting directions of the display units of each second display area are consistent with each other and correspond to a second view region from which only the second display areas can be viewed; and
the base substrate includes a base layer and a molded layer formed on the base layer; and a plurality of ribs are formed in the molded layer.

2. The dual-view display substrate according to claim 1 , wherein the ribs include first display unit supporting portions and second display unit supporting portions; the first display unit supporting portions correspond to the display units of the first display areas; and the second display unit supporting portions correspond to the display units of the second display areas.

3. The dual-view display substrate according to claim 2 , wherein the plurality of ribs are arranged in parallel.

4. The dual-view display substrate according to claim 3 , wherein a first angle is formed between a surface of one first display unit supporting portion along a counterclockwise direction and the normal direction of the display substrate; a second angle is formed between a surface of one second display unit supporting portion along a clockwise direction and the normal direction of the display substrate; and the first angle and the second angle are not 90 degrees at a same time.

5. The dual-view display substrate according to claim 4 , wherein a cross-section of each rib is an isosceles triangle; and two sides of the isosceles triangle correspond to one first display unit supporting portion and one second display unit supporting portion of the rib respectively, namely the first angle is equal to the second angle.

6. The dual-view display substrate according to claim 5 , wherein both the first angle and the second angle are 45 degrees.

7. The dual-view display substrate according to claim 4 , wherein a cross-section of each rib is a right trapezoid; and an upper base and an oblique leg of the right trapezoid correspond to one first display unit supporting portion and one second display unit supporting portion of the rib respectively, namely one of the first angle and the second angle is 90 degrees.

8. A dual-view display device, comprising the dual-view display substrate according to claim 1 .

9. The dual-view display device according to claim 8 , further comprising a sealing layer formed on the dual-view display substrate.

10. The dual-view display device according to claim 9 , wherein the sealing layer has a planar surface.

11. The dual-view display substrate according to claim 2 , wherein the base substrate includes a base layer and a molded layer formed on the base layer; and the ribs are formed in the molded layer.

12. The dual-view display substrate according to claim 3 , wherein the base substrate includes a base layer and a molded layer formed on the base layer; and the ribs are formed in the molded layer.

13. The dual-view display substrate according to claim 4 , wherein the base substrate includes a base layer and a molded layer formed on the base layer; and the ribs are formed in the molded layer.

14. The dual-view display substrate according to claim 5 , wherein the base substrate includes a base layer and a molded layer formed on the base layer; and the ribs are formed in the molded layer.

15. The dual-view display substrate according to claim 6 , wherein the base substrate includes a base layer and a molded layer formed on the base layer; and the ribs are formed in the molded layer.

16. The dual-view display substrate according to claim 7 , wherein the base substrate includes a base layer and a molded layer formed on the base layer; and the ribs are formed in the molded layer.
