[0038] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings.

[0039] It should be noted that, in the case of no conflict, the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other.

[0040] It should be noted that: similar signs and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0041] Embodiment one

[0042] Please refer to Figures 1-5As shown in the figure, a display screen for displaying different pictures at different angles comprises a grating array layer 1 and a cover plate 2 arranged in close contact with the grating array layer 1, and a display screen 3 is arranged on one side of the cover plate 2 relative to the grating array layer 1. The grating array layer 1 comprises a plurality of parallel grating columns 11, and each grating column 11 comprises a reflective spherical surface 110 and a column body 111. The reflective spherical surface 110 has a first reflection point 112 and a second reflection point 113 on two sides thereof.

[0043] The column body 111 is bisected by the first reflection point 112 and the second reflection point 113 into a first picture conveying area 114 and a second picture conveying area 115. Pictures in the plurality of first picture conveying areas 114 are reflected by the first reflection point 112 to form a first picture display area, and pictures in the plurality of second picture conveying areas 115 are reflected by the second reflection point 113 to form a second picture display area.

[0044] As shown in the figure, Figure 4 and Figure 5 the angles of the first reflection point 112 and the second reflection point 113 are different, so the first picture display area and the second picture display area formed after being reflected to the outside are also at different angles. Thus, a user can only view the corresponding picture display at the corresponding angle, thereby achieving privacy protection for the viewer and allowing a single display screen 3 to display multiple pictures.

[0045] The widths of the first picture conveying area 114 and the second picture conveying area 115 in the column body 111 are the same as the width of the column body 111.

[0046] The display screen 3 has a first display picture segment area 31 and a second display picture segment area 32 corresponding to the first picture conveying area 114 and the second picture conveying area 115, respectively, and the plurality of first display picture segment areas 31 and second display picture segment areas 32 are arranged in order in alternation.

[0047] Thus, when the display screen 3 displays two pictures, the two pictures are equally divided, and the two pictures after being equally divided are alternately distributed to form the first display picture segment area 31 and the second display picture segment area 32. Thus, the display screen can project the first display picture segment area 31 and the second display picture segment area 32 into the corresponding first picture conveying area 114 and second picture conveying area 115 and finally reflect them to the outside through the first reflection point 112 and the second reflection point 113 for display.

[0048] The first display picture segmentation area 31 and the second display picture segmentation area 32 are combined to form a first display picture and a second display picture respectively. When the display screen 3 displays the pictures, the pictures need to be processed, for example, a picture A is divided into several equal parts, and a picture B is also divided into several equal parts. Each equal part of the picture A (the first display picture segmentation area 31) + each equal part of the picture B (the second display picture segmentation area 32) = the width of the light column 11. The picture A and the picture B have different exit angles after passing through the light column 11, so that different angles can see two different pictures. Since the light exits at a specific angle, the observer who sees the picture A cannot see the picture B, and the observer who sees the picture B cannot see the picture A.

[0049] The picture equal division method can convert a picture, for example, a JPG picture, into a digital matrix, divide the digital matrix according to the width of the light column 11, and combine the two digital matrices A and B in the form of columns to form a picture in which the A and B pictures are alternately arranged.

[0050] The display screen for displaying different pictures at different angles provided in the embodiment of the present disclosure further includes a control device. The control device includes a controller, a power management module, an audio / video processing module, a communication module, and a picture display processing module. The power management module is electrically connected with the power supply, the controller, and the display screen 3, and is suitable for supplying power to the controller and the display screen 3.

[0051] The controller is electrically connected with the display screen 3, the audio / video processing module, the communication module, and the display processing module. The display processing module is electrically connected between the audio / video processing module and the display screen, and realizes the equal division and alternate distribution of the two pictures to be displayed.

[0052] The controller, the power management module, the audio / video processing module, the communication module, and the picture display processing module are mature and perfect prior art, so that the conventional and known components on the market can be used for cooperation and application. No further elaboration is made in the embodiment.
