[0003] As a high-tech product with a sci-fi sense and capable of significantly increasing user attention, for the transparent display glass assembly product to ensure that the image quality processing and human-computer interaction experience control functions of the transparent display reach the best effects simultaneously, existing methods generally adopt a dual-core control board system platform architecture for design. Especially with the development of technologies such as AR, VR, and MR, higher requirements are put forward for the performance, especially the display performance, of transparent display products. Separating the display and control by independent hardware boards and software system platforms to fully guarantee the improvement of the overall product performance has become the optimal solution for transparent display products.

[0025] To make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0026] Regarding the "first", "second", etc. used in this article, they do not particularly refer to the order or sequence, nor are they used to limit the present application. They are merely used to distinguish components or operations described with the same technical terms.

[0027] Please refer to Figure 1 , which is the system architecture diagram of the transparent display screen of the dual-system platform architecture according to an embodiment of the present application; as shown in the figure, the transparent display screen 1 of the dual-system platform architecture includes a first motherboard 2, a second motherboard 3, a TCON board 4, and a transparent display screen 5. The first motherboard 2 is connected to the second motherboard 3, the second motherboard 3 is connected to the TCON board 4, and the TCON board 4 is connected to the transparent display screen 4. The first motherboard 2 internally integrates a first system, the second motherboard 3 internally integrates a second system, the second system and the first system are independent systems, and the first system and the second system constitute the dual-system of the transparent display screen 5.

[0028] By default, that is, when the system is not switched, the first motherboard 2 outputs a display signal to the second motherboard 3, and the display signal output can be implemented through various common interfaces such as HDMI, VGA, DVI, etc. The second motherboard 3 receives the display signal through a display interface that matches the first motherboard 2, performs signal conversion and processing of the display image quality, and drives the transparent display screen 5 to display through the TCON board 4. At this time, the operation interface of the first system is displayed on the transparent display screen 5.

[0029] Refer back to Figure 1As shown, the first motherboard 2 has an external communication interface and an internal communication interface. The user can send a dual-system switching instruction to the first motherboard 2 through the external communication interface, or can also send other control instructions to the first motherboard 2 through the external communication interface to implement the human-computer interaction control function of the external system based on the external communication interface. The external communication interface includes at least one of an Ethernet communication interface, an RS485 communication interface, and a USB interface.

[0030] The internal communication interface is connected to the second motherboard 3. The first motherboard 2 sends a communication signal to the second motherboard 3 through the internal communication interface. The communication signal is a first switching instruction or a second switching instruction. In this way, the first motherboard 2 and the second motherboard 3 implement the dual-system switching application through the external communication interface and the internal communication interface and integrate the dual-system switching logic control software. The internal communication interface includes at least one of an Ethernet communication interface, a serial communication interface, and a USB interface.

[0031] In this embodiment, the dual-system platform architecture transparent display screen 1 further includes a power supply 5 for supplying power to the dual-system platform architecture transparent display screen 1. The power supply 5 is connected to the first motherboard 2, the second motherboard 3, and the TCON board 4. Specifically, the power supply 5 provides a DC12V voltage for the first motherboard 2 and the second motherboard 3, and the power supply 5 provides a DC24V voltage for the TCON board 4, but is not limited thereto.

[0032] If the dual-system function is to be enabled so that both the first motherboard 2 and the second motherboard 3 can implement the function of the human-computer interaction application service and give full play to the performance and functional advantages of the dual system, a software control module needs to be integrated in the first motherboard 2, and the switching between the first system and the second system is realized through the software control module.

[0033] Please refer to Figure 2 together, which is the switching flow chart of the dual-system switching method of the dual-system platform architecture transparent display screen in an embodiment of the present application; as shown, the dual-system switching method S of the dual-system platform architecture transparent display screen includes the following steps S1 and S2. In step S1, the user sends a dual-system switching instruction to the first motherboard 2. On the basis of the operation interface of the first system being displayed on the transparent display screen 5, the user can send a dual-system switching instruction to the first motherboard 2 through the external communication interface provided by the first motherboard 2.

[0034] In step S2, after the first motherboard 2 receives the dual-system switching instruction, it judges the switching instruction. If the judgment result is to switch to the display of the second system screen, the first motherboard 2 sends a first switching instruction to the second motherboard 3 through the internal communication interface. After receiving the first switching instruction, the second motherboard 3 switches the display screen output by the first motherboard 2 received through display interfaces such as HDMI, VGA, and DVI that is being displayed to the display screen of the second system built in the second motherboard 3 itself. At this time, the operation interface of the second system is displayed on the transparent display screen 5, thereby providing a display service different from that of the first motherboard 2 and realizing dual-system switching.

[0035] As described above, when the user needs to switch back to the display service provided by the first system of the first motherboard 2, the user can send the dual-system switching instruction to the first motherboard 2 again through the external communication interface provided by the first motherboard 2. At this time, the judgment result is to switch back to the display of the first system screen, then the first motherboard 2 sends a second switching instruction to the second motherboard 3 through the internal communication interface. After receiving the second switching instruction, the second motherboard 3 switches the displayed second-system display screen to the input screen display of the first system. At this time, the operation interface of the first system is displayed on the transparent display screen 5.

[0036] In one embodiment, referring back to Figure 1 As shown, the transparent display screen 1 of the dual-system platform architecture further includes a display touch component 6 and a multi-way control switch 7. The display touch component 6 is connected to the multi-way control switch 7. The multi-way control switch 7 is connected to the first motherboard 2 and the second motherboard 3, and the multi-way control switch 7 is used to switch between the display touch component 6 and the first motherboard 2 and the second motherboard 3. In this embodiment, the display touch component 6 includes a touch screen 61 and a touch driving board 62. The touch screen 61 is connected to the touch driving board 62, and the touch driving board 62 is connected to the multi-way control switch 7.

[0037] By default, that is, when the system is not switched, the multi-way control switch 7 defaults to control the interface between the touch driving board 62 and the first motherboard 2 to provide the touch control service of the first system based on the first motherboard 2. After switching, the multi-way control switch 7 controls the interface between the touch driving board 62 and the second motherboard 3 and disconnects the interface with the first motherboard 2 to provide the touch control service of the second system based on the second motherboard 3. In this embodiment,

[0038] The multi-channel control switch 7 has a communication interface and a switch module (not shown in the figure). The communication interface is used to receive communication signals, which are the first switching instruction or the second switching instruction. The switch module controls the switching between the display touch component 6, the first motherboard 2, and the second motherboard 3 according to the first switching instruction and the second switching instruction. The multi-channel control switch 7 receives the first switching instruction and the second switching instruction of the first motherboard 2 through the communication interface and based on the software communication interface protocol to achieve switching control.

[0039] Please refer to Figure 3 and also refer to Figure 1 , Figure 3 which is a schematic diagram of the switching circuit principle of the multi-channel switch dual system in an embodiment of the present application; as shown in the figure, the communication interface of the touch drive board 62 is connected to the common contact (COM port) of the multi-channel control switch 7. By default, the first motherboard 2 is connected to the normally closed contact (NC port) of the multi-channel control switch 7 and can directly communicate with the touch drive board 62, so as to collect the touch screen signal and realize the touch interaction based on the first motherboard 2 system. The second motherboard 3 is connected to the normally open contact of the multi-channel control switch 7 and is disconnected from the touch drive board 62, and cannot collect the touch screen 61 signal.

[0040] When the first motherboard 2 sends the first switching instruction to the second motherboard 3, the first motherboard 2 simultaneously sends the first switching instruction to the multi-channel control switch 7, and the multi-channel control switch 7 switches the display touch component 6 to be connected to the second motherboard 3. Specifically, when the user controls the first motherboard 2 to send the first switching instruction to the multi-channel control switch 7 through the touch interface, the common contact (COM port) of the multi-channel control switch 7 will switch to the normally open contact (NO port), so that the second motherboard 3 can directly communicate with the touch drive board 62, and thus the second system of the second motherboard 3 can directly collect the touch screen 61 signal.

[0041] When the second motherboard 3 sends the second switching instruction to the first motherboard 2, the first motherboard 2 simultaneously sends the second switching instruction to the multi-channel control switch 7, and the multi-channel control switch 7 switches the display touch component 6 to be connected to the first motherboard 2. Specifically, the user sends a switching instruction to the first motherboard 2 through the touch interface provided by the second motherboard 3, and then the first motherboard 2 forwards the switching instruction to the multi-channel control switch 7. After that, the common contact (COM port) of the multi-channel control switch 7 will switch back to the normally closed contact (NC port), so as to realize the communication between the first system of the first motherboard 2 and the touch screen 61 again.

[0042] In this embodiment, switching control software buttons (not shown in the figure) are respectively provided on the operation interfaces of the first system and the second system. By operating the switching control software buttons, the user controls the first circuit board 2 to send a first switching instruction or a second switching instruction to the second circuit board 3 on the one hand, and send a first switching instruction or a second switching instruction to the multi-channel control switch 7 on the other hand.

[0043] The following will take the application of the dual-system platform architecture of this application to the transparent OLED display window product of high-speed trains as an example to elaborate on the beneficial effects of this application in detail.

[0044] Please refer to Figure 4 With Figure 5 , which is the system architecture diagram and the dual-system switching flow chart of the transparent OLED display window product with the dual-system switching function in an embodiment of this application; as shown in the figure, in the transparent OLED display window product with the dual-system switching function in this embodiment, the first circuit board uses a human-machine interaction control board, the second circuit board uses a display control board, the transparent display screen is a transparent OLED display screen, and the touch screen uses a capacitive touch screen. The human-machine interaction control board and the display control board form the core control board card of the window dual system. By default, the system of the human-machine interaction control board provides the display and touch control screens, which are mainly used for communicating with the in-train passenger information system (PIS) of the train, and providing services such as train stop information display, synchronous playback of advertising streaming media videos, local storage of station information query, and Internet access services.

[0045] The display control board mainly undertakes the display driving and image quality processing functions of the transparent OLED display screen. However, since the display control board adopted in this embodiment has powerful audio and video image processing performance and touch following performance, while completing the display driving function, it can provide value-added services such as video conferencing, whiteboard, and remote information publishing. Therefore, in order to give full play to the functions and performance of the display control board, promote the improvement of the overall functions and performance of the transparent OLED window, and meet the requirements of users for multi-functional and high-performance products, it is necessary to integrate the dual-system switching solution provided by this application to realize the arbitrary switching between the human-machine interaction control board system and the display control board system of the transparent OLED display window in this embodiment. The specific solution is described as follows:

[0046] 1. The human-machine interaction control board provides a display screen to the display control board through the HDMI interface. The RS485 communication interface is used as the communication control interface between the human-machine interaction control board and the display control board to realize the transmission of dual-system switching instructions between the boards.

[0047] 2. As a human-machine interaction medium, the driving interface of the capacitive touch screen is a USB interface. Therefore, there are only two USB signal lines, namely D- and D+, for the signal interface when the capacitive touch screen switches between the human-machine interaction control board and the display control board.

[0048] 3. The dual-channel switching control switch uses a dual-channel relay, which can realize the switching of the control signal lines D- and D+ of the capacitive touch screen. The dual-channel switching control switch is configured with an RS232 communication interface and communicates with the human-machine interaction control board through the RS232 interface to receive the switching instruction of the human-machine interaction control board, thereby controlling the jump of the relay contact of the dual-channel switching control switch.

[0049] 4. The signal lines D- and D+ of the touch drive USB interface of the touch drive board are connected to the common pole COM port of the dual-channel switching control switch relay. The touch control USB interface signal line of the human-machine interaction control board is connected to the normally closed contact NC port of the dual-channel switching control switch relay, and the touch control USB port signal line of the display control board is connected to the normally open contact NO of the dual-channel switching control switch relay.

[0050] 5. The transparent OLED display screen is defaultly provided with display and touch control services by the system of the human-machine interaction control board. When switching is required, the user only needs to operate the switching control software button on the UI interface of the human-machine interaction control board, and the display and touch control interface can be switched to the display control board by using the software and hardware switching circuit, and the display control board provides display and touch control services.

[0051] 6. When the user operates the switching control software button on the UI interface of the human-machine interaction control board, on the one hand, the human-machine interaction control board sends the first switching instruction to the dual-channel switching control switch through the RS232 interface, and on the other hand, it sends the first switching instruction to the display control board through the RS485 interface. In other words, the human-machine interaction control board sends the first switching instruction to the dual-channel switching control switch and the display control board simultaneously.

[0052] 7. After receiving the first switching instruction, the dual-channel switching control switch switches from the normally closed contact NC port to the normally open contact NO port through the common contact COM port, controls the interface between the touch drive board and the display control board, and disconnects the interface with the human-machine interaction control board. The capacitive touch screen provides touch control services to the system of the display control board.

[0053] 8. At the same time, after receiving the first switching instruction, the display control board turns off the display screen input by the system of the human-machine interaction control board through the HDMI interface, and switches to the display screen output by its own system, thereby finally realizing the switching of the transparent OLED display screen from being provided with display and touch control services by the system of the human-machine interaction control board to being provided with display and touch control services by the system of the display control board.

[0054] 9. On the basis that the display control board system provides display and touch services, a switching control software button is also set on its display interface. The user operates the switching control software button to control the display control board to send a second switching instruction to the human-machine interaction control board through the RS485 interface.

[0055] 10. After receiving the second switching instruction, the human-machine interaction control board forwards the second switching instruction to the dual-channel switching control switch through the RS232 interface. After receiving the second switching instruction, the dual-channel switching control switch interfaces with the capacitive touch screen from the normally open contact NO port to the normally closed contact NC port through the common contact COM port and disconnects the interface with the display control board. The capacitive touch screen provides touch services to the human-machine interaction control board system.

[0056] 11. At the same time, the display control board turns off the display screen output by its own system and switches to the display screen input by the system of the human-machine interaction control board through the HDMI interface, thereby finally realizing the switching of the transparent OLED display screen from providing display and touch services by the system of the display control board to providing display and touch services by the system of the human-machine interaction control board.

[0057] The above steps complete a cycle of the system switching process of the transparent OLED display window product.

[0058] In summary, the present application provides a dual-system switching method for a transparent display screen with a dual-system platform architecture. The present application constructs a dual-system platform for the transparent display screen through the first motherboard and the second motherboard. On the basis of the dual-system platform architecture, a software control module is integrated in the first motherboard, and the switching between the first system and the second system is realized through the software control module. In addition, the present application also integrates a dual-channel switching control switch on the basis of the dual-system platform architecture, and controls the switching between the touch component and the first motherboard and the second motherboard through the dual-channel switching control switch, that is, a solution combining software and hardware systems is adopted to realize the switching of the dual system.
