Figure 3 Shown is Figure 2 The enlarged schematic diagram of the position A of Figure 4 The circuit block diagram of the display screen 10 in an embodiment of this application is shown.

[0044] Please Figures 1-4 , the display screen 10 provided by an embodiment of this application, the display screen 10 includes a first display screen 110, a second display screen 120 and a third display screen 130 which are stacked, and a controller 140.

[0045] The controller 140 is electrically connected to the first display screen 110, the second display screen 120 and the third display screen 130 respectively. The controller 140 is used to control the first display screen 110 to display a first image, control the second display screen 120 to display a second image, and / or control the third display screen 130 to display a third image.

[0046] It is possible that the controller 140 controls the first display screen 110 to display a first image; it is also possible that the controller 140 controls the second display screen 120 to display a second image; it is also possible that the controller 140 controls the third display screen 130 to display a third image; of course, it is also possible that the controller 140 controls the first display screen 110 to display a first image and controls the second display screen 120 to display a second image; it is also possible that the controller 140 controls the second display screen 120 to display a second image and controls the third display screen 130 to display a third image; it is also possible that the controller 140 controls the first display screen 110 to display a first image and controls the third display screen 130 to display a third image; of course, it is also possible that the controller 140 controls the first display screen 110 to display a first image, controls the second display screen 120 to display a second image, and controls the third display screen 130 to display a third image.

[0047] Wherein, the first display screen 110 includes a first screen body and a first flexible cable 111, the second display screen 120 includes a second screen body and a second flexible cable 121, the third display screen 130 includes a third screen body and a third flexible cable 131, and the controller 140 is electrically connected to the first flexible cable 111, the second flexible cable 121, and the third flexible cable 131 respectively, so as to control the first screen body to display a first image, control the second screen body to display a second image, and / or control the third screen body to display a third image.

[0048] In this way, the first display screen 110 can be made to display a first image, the second display screen 120 can be controlled to display a second image, and / or the third display screen 130 can be controlled to display a third image according to the user's usage requirements, that is to say, at least one of the first display screen 110, the second display screen 120, and the third display screen 130 can be made to display an image according to the user's usage requirements. For example, one of the first display screen 110, the second display screen 120, and the third display screen 130 can be made to display an image, or the first display screen 110 can be made to display a first image, the second display screen 120 can be made to display a second image, and the third display screen 130 can be made to display a third image to simultaneously display images from different perspectives, which can provide a broader space for the application and promotion of the display screen 10.

[0049] In some embodiments, please refer to Figure 5, the controller 140 includes a first image module 141, a second image module 142, a third image module 143, a power module 144, and a control module 145. The first image module 141 is electrically connected to the first display screen 110 to control the first display screen 110 to display a first image; the second image module 142 is electrically connected to the second display screen 120 to control the second display screen 120 to display a second image; the third image module 143 is electrically connected to the third display screen 130 to control the third display screen 130 to display a third image; the power module 144 is electrically connected to at least one of the first image module 141, the second image module 142, and the third image module 143 by means of the control module 145.

[0050] The controller 140 may further include three switches respectively electrically connected to the first image module 141, the second image module 142, and the third image module 143. The control module 145 is used to control the opening and closing of the three switches. The three switches may all be transistors 1451. The control module 145 is used to provide an opening voltage to the control terminal of the transistor 1451, so as to energize the first image module 141, the second image module 142, and / or the third image module 143, and further enable the first display screen 110, the second display screen 120, and / or the third display screen 130 to display corresponding images.

[0051] In some embodiments, the controller 140 further includes a composite image module 146. The composite image module 146 is electrically connected to the first image module 141, the second image module 142, and the third image module 143 respectively (as Figure 6 shown), so that the first image displayed on the first display screen 110, the second image displayed on the second display screen 120, and the third image displayed on the third display screen 130 can be spliced into a composite image.

[0052] It may be that the composite image module 146 divides the composite image into a first image, a second image, and a third image. The first image module 141 is used to receive the signal corresponding to the first image from the composite image module 146, the second image module 142 is used to receive the signal corresponding to the second image from the composite image module 146, and the third image module 143 is used to receive the signal corresponding to the third image from the composite image module 146. In this way, the first image displayed on the first display screen 110, the second image displayed on the second display screen 120, and the third image displayed on the third display screen 130 can be spliced into a composite image.

[0053] That is to say, the first image is a part of the composite image, the second image is another part of the composite image, and the third image is yet another part of the composite image. The first image, the second image, and the third image can be spliced into the composite image. Combining the first display screen 110, the second display screen 120, and the third display screen 130 are stacked. In this way, the composite image presented by the display screen 10 can have a 3D stereoscopic effect, or the composite image presented by the display screen 10 can have the visual sense of a wide-angle shot. For example, the first image, the second image, and the third image are images from different perspectives, and one of the first image, the second image, and the third image is an image with a wide-angle perspective. In this way, the composite image can have the visual sense of a wide-angle shot, thereby reducing the discomfort in the user's vision and also being beneficial to broadening the application of the display screen 10.

[0054] In some embodiments, the first display screen 110, the second display screen 120, and the third display screen 130 include the same pixel arrangement structure.

[0055] Define the plane perpendicular to the thickness direction of the first display screen 110 as the target plane. The first display screen 110, the second display screen 120, and the third display screen 130 all include a plurality of sub-pixels. The sub-pixels of the first display screen 110, the corresponding sub-pixels on the second display screen 120, and the corresponding sub-pixels on the third display screen 130 overlap with each other in the orthographic projection within the target plane.

[0056] The first display screen 110, the second display screen 120, and the third display screen 130 including the same pixel arrangement structure is conducive to enabling the first image displayed by the first display screen 110, the second image displayed by the second display screen 120, and the third image displayed by the third display screen 130 to be spliced into the composite image, and the adjacent two of the first image, the second image, and the third image can be well connected, which is beneficial to improving the quality of the composite image.

[0057] As Figure 7 shown, the structures and sizes of the display areas of the first display screen 110, the second display screen 120, and the third display screen 130 are the same.

[0058] The orthographic projections of the display areas of the first display screen, the second display screen 120, and the third display screen 130 on the target plane overlap with each other.

[0059] In this way, it is convenient to adaptively adjust the first image displayed by the first display screen 110, the second image displayed by the second display screen 120, and the third image displayed by the third display screen 130 according to the composite needs, and the overlapping imaging between the adjacent two of the first image, the second image, and the third image can be reduced, which is beneficial to improving the imaging effect and the quality of the composite image.

[0060] In some embodiments, as Figure 7As shown, the display screen 10 further includes a touch screen 150. It is defined that one of the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side is the top-side display screen, and the touch screen 150 is disposed on the top side of the top-side display screen. The touch screen 150 is electrically connected to the controller 140, and the controller 140 is configured to control the first display screen 110 to display a first image, control the second display screen 120 to display a second image, and / or control the third display screen 130 to display a third image according to a touch command from the touch screen 150.

[0061] It can be that the first display screen 110 is the one among the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side; it can also be that the second display screen 120 is the one among the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side; it can further be that the third display screen 130 is the one among the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side; specifically, in the embodiments such as Figure 2 , Figure 3 and Figure 7 shown, the first display screen 110 is the one among the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side, that is to say, the first display screen 110 is the top-side display screen.

[0062] Specifically, the touch command of the touch screen 150 includes a first command for controlling the first display screen 110 to display a first image; and / or, a second command for controlling the second display screen 120 to display a second image; and / or, a third command for controlling the third display screen 130 to display a third image.

[0063] It can be that the touch command of the touch screen 150 includes the first command, it can also be that the touch command of the touch screen 150 includes the second command, it can further be that the touch command of the touch screen 150 includes the third command; of course, it can also be that the touch command of the touch screen 150 includes the first command and the second command; it can be that the touch command of the touch screen 150 includes the first command and the third command; it can be that the touch command of the touch screen 150 includes the second command and the third command; of course, it can further be that the touch command of the touch screen 150 includes the first command, the second command, and the third command.

[0064] It can be understood that when the touch command of the touch screen 150 includes a first command for controlling the first display screen 110 to display a first image, the controller 140 is used to control the first display screen 110 to display the first image. When the touch command of the touch screen 150 includes a second command for controlling the second display screen 120 to display a second image, the controller 140 is used to control the second display screen 120 to display the second image. When the touch command of the touch screen 150 includes a third command for controlling the third display screen 130 to display a third image, the controller 140 is used to control the third display screen 130 to display the third image.

[0065] In this way, the user can trigger the first command, the second command, and / or the third command as needed, and more conveniently make the first display screen 110 display the first image, the second display screen 120 display the second image, and / or the third display screen 130 display the third image through the touch function, which can improve the user experience and is beneficial to expanding the application scope of the display screen 10.

[0066] Of course, the present application is not limited to this. The touch command may further include a composite command for splicing the first image displayed on the first display screen 110, the second image displayed on the second display screen 120, and the third image displayed on the third display screen 130 into a composite image.

[0067] When the touch command includes a composite command, the controller 140 is used to splice the first image displayed on the first display screen 110, the second image displayed on the second display screen 120, and the third image displayed on the third display screen 130 into a composite image, which can meet the touch application of the composite image.

[0068] In some embodiments, one of the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side is defined as the top-side display screen, and the display screen 10 further includes a cover plate 160 provided on the top side of the top-side display screen (as Figure 3 shown).

[0069] In this way, the cover plate 160 can be used to protect the first display screen 110, the second display screen 120, and the third display screen 130, and improve the reliability of the display screen 10.

[0070] In some embodiments, one of the first display screen 110, the second display screen 120, and the third display screen 130 located at the topmost side is defined as the top-side display screen, and the thickness of the top-side display screen is 0.5 mm - 0.7 mm.

[0071] Optionally, the thickness of the top-side display screen is 0.5 mm, 0.6 mm, or 0.7 mm.

[0072] Exemplarily, the thickness of the first display screen 110 is 0.67 mm.

[0073] Set the thickness of the top - side display screen to be 0.5 mm - 0.7 mm, so that the thickness of the top - side display screen is relatively thin. When the first display screen 110 and the second display screen 120 overlap each other, it can effectively reduce the visual discomfort caused by the height difference between the screens, which is beneficial to improving the display effect of the display screen 10.

[0074] In some embodiments, the display screen 10 further includes a first adhesive layer 171 disposed between the first display screen 110 and the second display screen 120, a second adhesive layer 172 disposed between the second display screen 120 and the third display screen 130, and a third adhesive layer 173. The third adhesive layer 173 is disposed between the first display screen 110 and the cover plate 160 or between the first display screen 110 and the touch screen 150.

[0075] The first adhesive layer 171, the second adhesive layer 172, and the third adhesive layer 173 are all optical adhesive layers.

[0076] The connection between the first display screen 110 and the second display screen 120, between the second display screen 120 and the third display screen 130, and between the first display screen 110 and the cover plate 160 by means of adhesion is beneficial to improving the integrity and connection reliability of the display screen 10.

[0077] In some embodiments, the second display screen 120 is a transparent display screen.

[0078] It can be that the second display screen 120 displays a second image, or it can be that the second display screen 120 is in a transparent state. With such a setting, it is convenient for the combined application and individual application of the first display screen 110 and the third display screen 130. While improving the flexibility of the display screen 10, it can also improve the image quality when the first display screen 110 and the third display screen 130 are combined and individually applied.

[0079] In some implementations, the controller 140 is used to enable the first image displayed on the first display screen 110, the second image displayed on the second display screen 120, and the third image displayed on the third display screen 130 to be spliced into a composite image.

[0080] The composite image presented by the display screen 10 can have a 3D stereoscopic effect, or the composite image presented by the display screen 10 can have the visual sense of a wide - angle shot. For example, the first image, the second image, and the third image are images from different perspectives, and one of the first image, the second image, and the third image is an image with a wide - angle perspective. In this way, the composite image can have the visual sense of a wide - angle shot, thereby reducing the visual discomfort of the user and also being beneficial to broadening the application of the display screen 10.

[0081] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0082] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
