[0059] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0061] Figure 1 FIG. 1 is a schematic diagram of a display system 100 provided by an embodiment of the present application.

[0062] As shown in FIG. 1, the display device control system 100 can include a display device 200 and a remote controller 300. The display device 200 can be various types of display devices, such as liquid crystal display devices, organic light-emitting diode display devices, organic light-emitting transistor display devices, plasma display devices, and the like. The remote controller 300 can be used to control the display device 200, for example, to send various control instructions to the display device 200, so that the display device 200 performs corresponding operations based on the control instructions. Figure 1 In some embodiments, the display device 200 can be an ultra-large-size display screen. An ultra-large-size display screen generally refers to a display screen that is relatively large in size relative to a common-size display screen. For example, an 85-inch, 95-inch, or 120-inch display screen, and the like.

[0063]

[0064] ​Large-sized displays typically do not offer touch functionality. To control such displays using traditional direct touchscreen methods, a touch mechanism would likely need to be added to the device itself. However, adding a touch mechanism to an ultra-large screen increases the manufacturing complexity and makes this process difficult.

[0065] Even with touch functionality, it's not very convenient to use due to screen size limitations, such as difficulty touching it from a height.

[0066] Building upon this, traditional remote controls, such as TV remotes, can only perform basic operations using the buttons. Touch-related commands (such as taking screenshots or switching focus areas) are difficult to execute. For example, some functions that primarily require touch (such as applications and games) typically do not support focus switching via the remote. Furthermore, basic operations like taking screenshots cannot be performed using a remote control.

[0067] One solution is to use an external mouse to achieve clicks or touches. However, the limitations of a mouse are also obvious, such as driver compatibility issues with wireless mice in Android systems, cable limitations of wired mice, the right mouse button being used as a back button, and the inability to adjust mouse movement speed.

[0068] Another solution is to control it via a secondary screen, which increases the cost of peripherals.

[0069] In view of this, one embodiment of this application provides a display system that can realize simulated touch screen operation on the display device using a remote control. It is suitable for controlling applications, games, pages, etc. that do not support touch screen function or do not support cross-point switching, or for large-size screens where it is not easy to add peripherals, to perform simulated touch screen operation on the display device.

[0070] In some embodiments, such as Figure 1 As shown, the display device 200 may be equipped with at least two infrared transceiver units 202 for emitting first infrared light and receiving reflected infrared light (e.g., second infrared light, third infrared light). The remote controller 300 may be equipped with an infrared reflector 302. The remote controller 300 may use the infrared reflector 302 to reflect the first infrared light and send control commands to the display device.

[0071] Figure 2 A schematic flowchart illustrating an exemplary control method for a display device provided in an embodiment of this application is shown. This method can be executed by the display device 200. The method is described in detail below.

[0072] In the initial state, the infrared transceiver unit 202 on the display device 200 can be in the off state, and the remote controller 300 can use its conventional operation mode to send control instructions to the display device 200, such as power-on instructions, power-off instructions, selection instructions, determination instructions, and the like.

[0073] In some embodiments, when the user wants to perform an operation (e.g., a touch operation) other than the conventional operation of the display device 200, the screen positioning function can be selected to enter, the infrared transceiver unit 202 is turned on, and the positioning function is entered.

[0074] It should be noted that the display device is a super large size screen, when the super large size screen needs to perform a touch screen operation scenario, for example, when some areas of the screen need to be captured, a switch key of the remote controller can be used to turn on the infrared transceiver unit, the infrared transceiver unit sends first infrared light to the side of the display device light direction, the infrared reflection device on the remote controller reflects the first infrared light, the infrared transceiver device receives the second infrared light reflected back, the remote controller can issue the next instruction to enter the simulated touch screen mode to the display device, using the confirmation key of the remote controller to first enter the touch screen mode, and then using the screenshot key of the remote controller to issue a screenshot instruction to the display device, the display device receives the instruction and implements area screenshot and other operation instructions according to the operation of the remote controller.

[0075] On the other hand, the remote controller can enter the simulated touch screen mode based on the confirmation key, when the remote controller presses the exit key and issues an exit instruction to the display device, the display device exits the simulated touch screen mode, at this time the remote controller is equivalent to a conventional remote controller, and can still implement control of the display device, the remote controller can still implement turning on and off the display device according to the key, or provide conventional remote controller control of the display device, for example, a television remote controller controls the operation of a television, but does not provide simulated touch screen mode control.

[0076] Specifically, as Figure 2As shown, in step S101, the first infrared light is emitted and the second infrared light is received by using at least two infrared transceiver units; the second infrared light includes the reflected light generated by the remote controller of the display device reflecting the first infrared light at the first position. In some embodiments, the infrared transceiver units, such as infrared transmitting and receiving devices, can be arranged around the display device according to the required accuracy of receiving the second infrared light. Specifically, in an alternative embodiment, the infrared transceiver units can be arranged at any two corners of the display device, and the infrared transceiver units are used for emitting and receiving infrared light, wherein the side for reflecting and receiving infrared light is arranged at the side of the light emitting direction of the display device, and the infrared reflecting device, which can be an infrared reflecting sheet, is arranged on the remote controller for reflecting infrared light. The remote controller has a switch for opening the infrared transceiver units, and after the infrared transceiver units are opened, the infrared transceiver units send the first infrared light, the reflecting device reflects the first infrared light, and the infrared transceiver units receive the second infrared light reflected by the reflecting device.

[0077] It should be noted that, for example, after the remote controller opens the infrared transceiver units, the switch is pressed again, and then the infrared transceiver units are closed.

[0078] In step S102, the first position is mapped as a first light point on the display device according to the second infrared light and the arrangement position of the at least two infrared transceiver units; the reflecting position of the reflecting device of the remote controller, i.e., the reflection point, can be determined according to the second infrared light received by the at least two infrared transceiver units, so as to calculate the distance of the two second infrared lights to determine the spatial position of the remote controller, i.e., the first position. Herein, the distance of the remote controller from the infrared transmitting and receiving units can be determined by using the time for emitting the first infrared light and receiving the second infrared light and the propagation speed of the infrared light. It should be noted that the infrared transceiver units can further determine the spatial position of the remote controller, such as the distance of the remote controller from the display device, the position of the remote controller relative to the display device, and the direction of the remote controller pointing to the display device, by using the reflection angle and the reflection distance of the second infrared light. Thus, the pointing angle of the remote controller is mapped on the display device by using the calculation result to form the first light point, which can be a mouse pointer or just a light point that can be accurately displayed on the screen of the display device.

[0079] It should be noted that when the remote controller points to the center of the screen of the display device, the first light point is directly displayed at the center of the screen.

[0080] In step S103, the control instruction of the remote controller is received and the third infrared light is received by using the at least two infrared transceiver units; the third infrared light includes the reflected light generated by the remote controller of the display device after reflecting the first infrared light in the second position; specifically, in some embodiments, the remote controller first issues an entering analog touch screen instruction, which can be specifically implemented by setting a confirmation button on the remote controller, and when the user presses the confirmation button, the display device enters the analog touch mode; at this time, when the remote controller moves according to the analog touch screen operation, no matter whether it is moving away from or approaching the display device, moving laterally or the angle of the remote controller pointing to the display device is offset, etc., the reflection device reflects the first infrared light, and the infrared transceiver unit receives the third infrared light.

[0081] In step S104, the second position of the remote controller of the display device is mapped as a second light point on the display device according to the setting position of the at least two infrared transceiver units; specifically, in some embodiments, the infrared transceiver unit displays the spatial position of the remote controller, i.e., the second position on the display device according to the third infrared light; for example, in order to drag a certain application of the display device, the analog touch screen mode is entered, the position of the second light point is adjusted by using the position of the first light point, the second light point starts from the first light point, the second light point is displayed on the screen in real time, and the second light point appears on the application to be dragged, and then the dragging instruction is executed.

[0082] In step S105, the corresponding operation is executed according to the control instruction, the first light point and the second light point. Specifically, in some embodiments, corresponding buttons can be provided on the remote controller, or in order to save the button space of the remote controller, a single button on the remote controller can be used to issue one kind of instruction, two buttons on the remote controller can be used to issue one kind of instruction, etc. For example, as shown in FIG. 1, a screenshot button is installed on the remote controller, the display device receives the screenshot instruction when the screenshot button is pressed, and the full screen of the display device is captured; or the display device receives the screenshot instruction when the screenshot button is pressed for two seconds, the second light point starts from the first light point, and the position of the second light point on the display device is moved, a closed area is formed according to the track of the second light point on the screen, and the corresponding closed area is captured; similarly, if multiple closed areas appear at the same time, the multiple closed areas are all captured, and other areas not in the closed areas are replaced by a transparent background color. Figure 3 Figure 3

[0083] ​​In some embodiments, the keys of the remote controller can also have a drawing key. After the drawing key is pressed, the analog touch screen instruction of the display device receives an analog drawing instruction. The trajectory of the second light point from the first light point forms numerous light points. All the light points are displayed on the display device to form a drawing line. It should be noted that the drawing line can be a straight line, a curve or a combination of a straight line and a curve.

[0084] In some embodiments, the keys of the remote controller can also have an erasing key. After the erasing key is pressed, the analog touch screen instruction of the display device receives an erasing instruction. The display device directly displays an erasing icon. The infrared receiving unit receives the fourth infrared light reflected by the remote controller. The third light point corresponding to the current position of the remote controller appears on the screen. The remote controller is pressed again to confirm the key. The third light point coincides with the erasing icon. The movement of the third light point (erasing icon) corresponds to the erasing of the movement area of the third light point. The erasing target can be a line or a picture drawn by the analog drawing instruction.

[0085] In some embodiments, the keys of the remote controller can also have a local magnification key. After the local magnification key is pressed, the analog touch screen instruction of the display device receives a local magnification instruction. The second infrared light covers the area that needs to be locally magnified. The confirmation key is pressed again to locally magnify the corresponding area. For example, if the line or the picture drawn by the analog drawing instruction needs to be locally magnified, the analog touch screen instruction of the display device receives a local magnification instruction to magnify the local part of the line or the picture.

[0086] It should be noted that in the above embodiments, the confirmation key of the remote controller sends the analog touch screen instruction. When other instructions are operated, the confirmation key is pressed again to indicate confirmation. Only when the analog touch screen instruction is initially needed, the confirmation key is pressed to enter the analog touch screen mode. After entering the analog touch screen mode, the confirmation key is pressed again, which does not mean that the analog touch screen instruction is sent again. Similarly, different instructions can be sent by the keys of the remote controller. The display device receives different instructions. Here, the instructions that the display device can receive include not only the analog touch screen instruction, the analog drawing instruction, the erasing instruction and the analog screenshot instruction in the above embodiments.

[0087] In some embodiments, as Figure 1As shown, in order to be able to accurately determine the position of the remote controller, infrared transceiver units can be installed at the four corners of the display device respectively, and four second infrared lights, third infrared lights, fourth infrared lights, and even possibly fifth infrared lights can be used to more accurately calculate the reflected infrared light, thereby calculating the spatial position (first position, second position, third position, etc.) of the remote controller, and thus completing the mapping of the light points (first light point, second light point, third light point, etc.) on the display device corresponding to the more accurate spatial position of the remote controller. Similarly, the setting of the infrared transceiver units can be increased around the display device according to actual conditions.

[0088] It should be noted that the method of the embodiments of the present application can be executed by a single device, such as a computer or a server, etc. The method of the embodiments can also be applied to a distributed scenario, and be completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only execute one or more steps in the method of the embodiments of the present application, and the multiple devices can interact with each other to complete the method.
