These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] The present application embodiment provides a display screen, please refer to Figure 1 , Figure 1 1 is a schematic diagram of the structure of a display screen provided in an embodiment of the present application, wherein the display screen 10 includes: a control component 11, a detection component 12 and a plurality of display modules 13. Here, the display screen 10 may be a light-emitting diode (LED) display screen. Compared with the projection function realized by a projector in the traditional projection mode, the LED display screen has the advantages of pure chromaticity, wide dynamic range, high brightness, high definition, low operating voltage, low power consumption, long life, impact resistance, large viewing angle and stable and reliable operation. Since the display screen 10 is used to project movies in a cinema, the size of the display screen 10 is generally large, so the display screen 10 may include a plurality of display modules 13 spliced ​​together.

[0039] The display module 13 includes: a box 131, and a receiving card 132 and at least one display panel 133 installed in the box 131, and the receiving card 132 is electrically connected to the at least one display panel 133. Here, the box 131 can provide a receiving space to install the receiving card 132 and the at least one display panel 133, and the receiving card 132 is located on the back of the display panel 133.

[0040] The receiving card 132 is a component that can receive an external signal and decode it. The receiving card 132 can be used to receive and process the video signal sent by the control component 11, so as to decode and convert the video signal into a signal that can be recognized by the display panel 133 according to a specific protocol and format, and then transmit it to at least one display panel 133. Exemplarily, when the display module 13 includes multiple display panels 133, the receiving card 132 is used to transmit signals to the multiple display panels 133.

[0041] The display panel 133 is used to display a screen according to the image data after receiving the image data. The number of the display panels 133 in the display module 13 can be one or more. For example, Figure 1 The display module 13 shown includes a display panel 133. The display panel 133 may include a plurality of light-emitting elements. For example, when the display screen 10 is an LED display screen, the light-emitting element is an LED chip. It should be noted that the LED chip may include an ordinary-sized LED chip, a mini-LED chip, or a micro-LED chip.

[0042] The control component 11 is electrically connected to the receiving card 132 in each display module 13, and is used to send a corresponding video signal to each receiving card 132. Here, the control component 11 can be used to control the display function of each display module 13, and the implementation process of the display function may include: the control component 11 processes the video source data into video data of a local image that needs to be displayed by multiple display modules 13, that is, a video signal, and then sends the video signal to the receiving card 132 in the corresponding display module 13; the receiving card 132 processes the received video signal into local image data that needs to be displayed by multiple display panels 133, and then transmits it to the corresponding display panel 133 respectively, and the display panel 133 displays the picture according to the image data.

[0043] The detection component 12 is electrically connected to a designated receiving card 132a, and the designated receiving card 132a is at least one receiving card 132 among the multiple receiving cards 132. Here, the detection component 12 is used to detect whether there is a hidden camera device, and feed back the detection result to the designated receiving card 132a. The designated receiving card 132a can be a receiving card 132 that is closer to the detection component 12 among the multiple receiving cards 132, so as to facilitate the electrical connection between the detection component 12 and the designated receiving card 132a. In addition, the detection component 12 can be electrically connected to one or more receiving cards 132. Exemplarily, Figure 1In the display screen 10 shown, the detection component 12 is electrically connected to one receiving card 132 , which is the receiving card n closest to it.

[0044] The control component 11 is configured to:

[0045] In response to receiving an abnormal signal sent by the designated receiving card 132a, the sending of the corresponding video signal to each receiving card 132 is interrupted. The abnormal signal is a signal generated by the designated receiving card 132a after the detection component 12 detects the hidden camera device.

[0046] Here, the detection component 12 can continuously send a first detection signal to the receiving card 132 when working. The first detection signal can reflect the detection result of the detection component 12. When the detection component 12 detects a sneak camera, the first detection signal will undergo an abnormal change. The abnormal change can include: changes in characteristic parameters such as waveform, amplitude, width and repetition frequency. Since the receiving card 132 is a component that can receive an external signal and decode it, the receiving card 132 can also process the first detection signal. In this way, when the first detection signal undergoes an abnormal change, the receiving card 132 can respond to the abnormal change in a timely manner, generate and send an abnormal signal to the control component 11, so that the control component 11 can respond to the abnormal signal in a timely manner to interrupt the video signal, and then each display module 13 will not display, thereby achieving the effect of preventing sneak shots and piracy.

[0047] In summary, the embodiment of the present application provides a display screen provided with a detection component, which can be used to detect a sneak camera device. Furthermore, since the detection component is electrically connected to a designated receiving card, and the designated receiving card is electrically connected to a control component, after the detection component detects the sneak camera device, the designated receiving card can generate an abnormal signal, and send the abnormal signal to the control component in real time, so that the control component can interrupt the video signal in time in response to the abnormal signal, thereby achieving the effect of preventing sneak shots, and further reducing the box office losses of movies caused by piracy.

[0048] Optionally, the display screen provided in the embodiment of the present application is a movie display screen.

[0049] The embodiment of the present application can interrupt the video signal in a variety of implementations, and two exemplary embodiments are described below:

[0050] In the first embodiment, please refer to Figure 2 , Figure 2 1 is a schematic diagram of the structure of another display screen provided in an embodiment of the present application, wherein the display screen 10 comprises: a control component 11, a detection component 12 and a plurality of display modules 13. The control component 11 comprises: a sending card 111, the sending card 111 is communicatively connected to the server 20, and is electrically connected to the receiving card 132 in each display module 13.

[0051] Among them, the server 20 is used to send the decrypted video source to the sending card 111. In order to prevent piracy, the video source of the movie to be played is generally encrypted. The server 20 stores the video source and key of the movie to be played. Then the server 20 can decrypt the video source through the key and send the decrypted video source to the sending card 111. In the present application, the server 20 and the sending card 111 can be both set in a backpack box located on the back of the display module 13, so that the sending card 111 communicates with the server 20 and improves the stability of the transmission of the decrypted video source, but the position of the server 20 provided in the embodiment of the present application is not limited to this and can be flexibly set.

[0052] The sending card 111 is configured as follows:

[0053] (1) Sending corresponding video signals to each receiving card 132 based on the decrypted video source.

[0054] The sending card 111 is used to convert the input signal (decrypted video source) into a signal (video signal) suitable for display by the display module 13, and send the video signal to the receiving card 132 through the transmission line. Exemplarily, the sending card 111 can have a built-in image processor and color management system to process and adjust the input signal to ensure high fidelity and stability of image quality.

[0055] Since the display screen 10 may include a plurality of display modules 13 spliced ​​together, each display module 13 needs to receive a corresponding video signal to display normally, so the sending card 111 is also used to split the input signal and transmit it to the receiving card 132 of each display module 13 based on the splicing method of the plurality of display modules 13, so as to realize the complete display of the image.

[0056] (2) In response to receiving an abnormal signal, interrupting the transmission of the corresponding video signal to each receiving card 132.

[0057] The abnormal signal generated by the receiving card 132 can be directly transmitted to the sending card 111, and the sending card 111 can respond to the abnormal signal in time and interrupt the video signal sent to the receiving card 132, so that each display module 13 does not display, thereby achieving the effect of preventing sneak shots and piracy. Therefore, in this implementation, the transmission process from the sending card 111 to multiple receiving cards 132 is interrupted, so that the sending card 111 responds to the abnormal signal more sensitively and can interrupt the transmission of the video signal in time when a sneak camera device is detected.

[0058] In the second embodiment, please refer to Figure 3 , Figure 31 is a schematic diagram of the structure of another display screen provided in an embodiment of the present application, wherein the display screen 10 comprises: a control component 11, a detection component 12 and a plurality of display modules 13. The control component 11 comprises: a sending card 111 and a security module 112, wherein the security module 112 is connected to the server 20 in communication and is at least electrically connected to the designated receiving card 132a, so that the security module 112 can receive an abnormal signal generated by the designated receiving card 132a.

[0059] The security module 112 is configured to:

[0060] In response to receiving the abnormal signal, an interruption instruction is sent to the server 20 , where the interruption instruction is used to instruct the server 20 to interrupt sending the decrypted video source to the sending card 111 .

[0061] Since the sending card 111 cannot directly control the server 20 to interrupt the transmission, the security module 112 can be set to send an interruption instruction to the server 20. In response to the interruption instruction, the server 20 can stop sending the decrypted video source to the sending card 111, or make each display module 13 not display. Therefore, in this implementation, the transmission process from the server 20 to the sending card 111 is interrupted, so that piracy can be prevented from the data source, further reducing the risk of piracy.

[0062] In the present application, the security module 112 can also be set in the backpack box to facilitate the communication connection between the security module 112 and the server 20 and improve the stability of sending interrupt instructions, but the position of the security module 112 provided in the embodiment of the present application is not limited to this and can be flexibly set.

[0063] In addition, in the international certification standard (Digital Cinema Initiatives, DCI) in the field of digital cinema, it is required that the display screen must meet the safety standard, that is, once the box of the display module is opened during the normal playback of the movie, the server must respond and stop the transmission, generally by installing a pressure sensor in each display module to detect whether the box is opened. Therefore, the security module 112 provided in the embodiment of the present application can also be used to receive a signal reflecting the detection result of the pressure sensor of each display module 13, and send the signal to the sending card 111 or the server 20. In this case, the security module 112 needs to be electrically connected to the receiving card 132 of each display module 13, and electrically connected to the sending card 111, so that the security module 112 can be used to implement anti-disassembly security control. In addition, the security module 112 combines the anti-disassembly security control and the anti-sneak photography security control, and can also avoid setting up other modules separately to save costs.

[0064] In the present application, the above two implementation methods can also be used at the same time. When the detection component detects a hidden camera device, the transmission process from the server to the sending card is interrupted, and the transmission process from the sending card to the receiving card is also interrupted, thereby ensuring that each display module does not display when a hidden camera device is detected.

[0065] In addition, based on the above two implementation methods, the present application embodiment also provides another signal transmission method, please refer to Figure 4 , Figure 4 1 is a schematic diagram of the structure of another display screen provided in an embodiment of the present application. The security module 112 is electrically connected to the sending card 111. The process of implementing anti-piracy for the movie screen 10 can be:

[0066] (1) The detection component 12 continuously sends the first detection signal to the receiving card 132 .

[0067] (2) The receiving card 132 processes the received first detection signal.

[0068] (3) When the first detection signal undergoes an abnormal change, the receiving card 132 generates an abnormal signal and sends the abnormal signal to the security module 112 .

[0069] (4) In response to receiving the abnormal signal, the security module 112 sends an interruption instruction to both the server 20 and the sending card 111.

[0070] (5) The server 20 responds to the interruption instruction and interrupts sending the decrypted video source to the sending card 111. Also, the sending card 111 responds to the interruption instruction and interrupts sending the corresponding video signal to each receiving card 132.

[0071] Figure 4 In the illustrated embodiment, the abnormal signal generated by the receiving card 132 is not directly transmitted to the sending card 111 , but is transferred through the security module 112 , thereby avoiding interference with the transmission process of the video signal between the receiving card 132 and the sending card 111 .

[0072] The following is a description of the detection components:

[0073] In the display screen provided in the embodiment of the present application, the principle of detecting the hidden camera device by the detection component includes multiple situations:

[0074] One detection principle is based on laser detection, please refer to Figure 1 The detection component 12 includes: a laser detection module, which is used to generate laser and receive the light spot reflected by the hidden camera device.

[0075] The receiving card 132 is configured as follows:

[0076] In response to the laser detection module receiving the light spot reflected by the hidden camera device, an abnormal signal is generated.

[0077] The laser detection module can generate laser, such as infrared light. When there is a hidden camera device within the detection range, the infrared light will be reflected by the hidden camera device, and the laser detection module can obtain the light point reflected by the hidden camera device, so that the first detection signal sent by the detection component 12 to the receiving card 132 will change abnormally, so the receiving card 132 can respond quickly and generate an abnormal signal. Exemplarily, the detection distance of the laser detection module can range from 10 cm to 50 meters.

[0078] Another detection principle is based on radio wave detection, please refer to Figure 1 The detection component 12 includes: an electric wave detection module, and the electric wave detection module is used to receive radio waves from the hidden camera device.

[0079] The receiving card 132 is configured as follows:

[0080] In response to the radio wave detection module receiving the radio wave of the hidden camera device, an abnormal signal is generated.

[0081] The hidden camera device may include: a wired device or a wireless device, wherein the wireless device emits radio waves for data transmission when working, and the radio wave detection module can detect the radio waves of the hidden camera device, so that the first detection signal sent by the detection component 12 to the receiving card 132 will change abnormally, so the receiving card 132 can respond quickly and generate an abnormal signal. Exemplarily, the frequency range of the radio waves detected by the radio wave detection module can be: 1 MHz-6500 MHz.

[0082] In the present application, the detection component 12 may include: any one of a laser detection module and an electric wave detection module. The detection component 12 may also include: a laser detection module and an electric wave detection module at the same time, thereby improving the adaptability to a variety of hidden camera devices, and further improving the accuracy of detecting hidden camera devices.

[0083] Optionally, refer to Figure 3 , the designated receiving card 132a is used to generate a high-level signal and a low-level signal based on the electrical signal detected by the detection component 12, and the abnormal signal is one of the high-level signal and the low-level signal.

[0084] The electrical signal detected by the detection component 12 is the first detection signal. Since the designated receiving card 132a has the function of processing signals, the designated receiving card 132a can process the first detection signal. When the received first detection signal undergoes an abnormal change, a high-level signal and a low-level signal are generated. When the received first detection signal does not undergo an abnormal change, the other of the high-level signal and the low-level signal is generated. In this way, the first detection signal can be simplified into a high-level signal and a low-level signal, so that the security module 112 can judge whether a hidden camera device is detected.

[0085] In the display screen provided in the embodiment of the present application, the setting position of the detection component includes multiple situations:

[0086] For one case, please refer to Figures 1 to 4 In the illustrated embodiment, the box 131 for installing the designated receiving card 132a is located in the frame area of ​​the display screen 10, and the detection component 12 is located in the frame area and is installed outside the box 131 where the designated receiving card 132a is located. Exemplarily, the frame area of ​​the display screen 10 may include: an upper frame area, a lower frame area, a left frame area, and a right frame area, and the detection component 12 may be located in any frame area. The display screen 10 provided in the embodiment of the present application may also include multiple detection components 12, so that a larger detection range can be achieved. Exemplarily, the multiple detection components 12 may be located in the above four frame areas respectively.

[0087] For another case, please refer to Figure 5 , Figure 5 It is an exploded view of a partial structure of another display screen provided in an embodiment of the present application. The box 131 for installing the designated receiving card 132a is located in the central area of ​​the display screen 10, and the detection component 12 and the designated receiving card 132a are installed in the same box 131. Since the principle of the detection component 12 to detect hidden camera devices is generally to detect infrared light or radio waves, and the display panel 133 is non-metallic, installing the detection component 12 in the box 131 where the designated receiving card 132a is located will not affect the detection function of the detection component 12. In addition, since the display screen 10 in a cinema is generally opposite to the seats, by setting the detection component 12 in the central area of ​​the display screen 10, the detection range of the detection component 12 can also cover the area where the seats are located as much as possible, which is convenient for detecting hidden camera devices.

[0088] In addition, the display screen 10 may further include a plurality of detection components 12 , a portion of the plurality of detection components 12 being located in the central area, and another portion being located in the frame area.

[0089] In summary, the embodiment of the present application provides a display screen provided with a detection component, which can be used to detect a sneak camera device. Furthermore, since the detection component is electrically connected to a designated receiving card, and the designated receiving card is electrically connected to a control component, after the detection component detects the sneak camera device, the designated receiving card can generate an abnormal signal, and send the abnormal signal to the control component in real time, so that the control component can interrupt the video signal in time in response to the abnormal signal, thereby achieving the effect of preventing sneak shots, and further reducing the box office losses of movies caused by piracy.

[0090] In a second aspect, an embodiment of the present application provides an anti-piracy method for a display screen, which is used for a control component in a display screen provided in any of the above embodiments, and the display screen also includes: a detection component and multiple display modules. The display module includes: a housing, a receiving card installed in the housing, and at least one display panel, and the receiving card is electrically connected to the at least one display panel. The control component is electrically connected to the receiving card in each display module, and is used to send a corresponding video signal to each receiving card. The detection component is electrically connected to a designated receiving card, and the designated receiving card is at least one receiving card among multiple receiving cards. The method includes:

[0091] In response to receiving an abnormal signal sent by a designated receiving card, the sending of corresponding video signals to each receiving card is interrupted. The abnormal signal is a signal generated by the designated receiving card after the detection component detects the hidden camera device.

[0092] In summary, the embodiment of the present application provides an anti-piracy method for a display screen, and the display screen is provided with a detection component, which can be used to detect a sneak camera device. In addition, since the detection component is electrically connected to a designated receiving card, and the designated receiving card is electrically connected to a control component, after the detection component detects the sneak camera device, the designated receiving card can generate an abnormal signal, and send the abnormal signal to the control component in real time, so that the control component can interrupt the video signal in time in response to the abnormal signal, thereby achieving the effect of preventing sneak shots, and further reducing the box office losses of movies caused by piracy.

[0093] The present application embodiment provides another anti-piracy method for display screens, please refer to Figure 6 , Figure 6 This is a flowchart of another anti-piracy method for a display screen provided by an embodiment of the present application. The method is used for a control component in a display screen provided by any of the above embodiments. The control component is connected to a server for communication. The server is used to send a decrypted video source to a sending card. The method includes:

[0094] Step 601: Send corresponding video signals to each receiving card based on the decrypted video source.

[0095] The control component can convert the input signal (decrypted video source) into a signal (video signal) suitable for display by the display module, and send the video signal to the receiving card through the transmission line. The control component can also split the input signal and transmit it to the receiving card of each display module based on the splicing method of multiple display modules, so as to realize the complete display of the image.

[0096] Step 602: In response to receiving an abnormal signal sent by a designated receiving card, interrupt the sending of corresponding video signals to each receiving card.

[0097] The abnormal signal generated by the receiving card can be directly transmitted to the control component, and the control component can respond to the abnormal signal in time and interrupt the video signal sent to the receiving card, so that each display module will not display, thereby achieving the effect of preventing sneak shots and piracy.

[0098] Step 603: In response to receiving the abnormal signal sent by the designated receiving card, an interrupt instruction is sent to the server.

[0099] The interrupt instruction is used to instruct the server to interrupt sending the decrypted video source to the sending card. In response to the interrupt instruction, the server can stop sending the decrypted video source to the sending card, or can make each display module stop displaying.

[0100] Step 602 and step 603 can be performed simultaneously. In this way, when the detection component detects a hidden camera device, the transmission process from the server to the sending card is interrupted, and the transmission process from the sending card to the receiving card is also interrupted, thereby ensuring that each display module does not display when a hidden camera device is detected.

[0101] In summary, the embodiment of the present application provides an anti-piracy method for a display screen, and the display screen is provided with a detection component, which can be used to detect a sneak camera device. In addition, since the detection component is electrically connected to a designated receiving card, and the designated receiving card is electrically connected to a control component, after the detection component detects the sneak camera device, the designated receiving card can generate an abnormal signal, and send the abnormal signal to the control component in real time, so that the control component can interrupt the video signal in time in response to the abnormal signal, thereby achieving the effect of preventing sneak shots, and further reducing the box office losses of movies caused by piracy.
