[0021] For the dual-system platform architecture, the display screen and touch screen of the intelligent transparent display window of rail transit often adopt an inverted installation method due to the limited on-vehicle installation environment. Therefore, the software interface and touch function generally rotate 180 degrees for normal display and normal touch. In the dual-core control board system solution, the signal conversion board needs to perform both display and software functions with touch. This results in a phenomenon that when switching between the two systems, the software interface and touch of one board are always reversely mismatched and cannot be operated.

[0022] When the dual-core control board of the transparent display screen of the dual-system platform architecture of the present application switches between the two systems, the reverse problem of touch and display can be solved without modifying any software code or touch screen parameters.

[0023] 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 drawings.

[0024] Regarding the "first", "second", etc. used herein, 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.

[0025] Please refer to Figure 1 and Figure 2, which is a schematic diagram of the software default and switching display solution 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 touch component 2, a display screen component 3, a switch component 4, a human-computer interaction main board 5, and a signal conversion board 6. The touch component 2 is connected to the switch component 4. In this embodiment, the touch component 2 includes a touch screen 21 and a touch control board 22. The touch screen 21 is connected to the touch control board 22, and the touch control board 22 is connected to the switch component 4. The touch screen 21 is used as a human-computer interaction medium and is installed in a flip-chip manner. The touch screen 21 selects a capacitive touch screen, and the drive interface selects a USB interface.

[0026] The display screen component 3 is connected to the signal conversion board 6. In this embodiment, the display screen component 3 includes a display screen 31 and a TCON board 32. The display screen 31 is connected to the TCON board 32, and the TCON board 32 is connected to the signal conversion board 6. The display screen 31 is used as a display medium and is installed in a flip-chip manner. The display screen 31 selects a transparent OLED screen, but is not limited thereto.

[0027] The switch component 4 is connected to the human-computer interaction main board 5 and the signal conversion board 6. The touch component 2 selects to be connected to the human-computer interaction main board 5 or the signal conversion board 6 through the switch component 4. By default, as Figure 1 shown, the switch component 4 is connected to the human-computer interaction main board 5, and the switch component 4 is disconnected from the signal conversion board 6. The human-computer interaction main board 5 is connected to the signal conversion board 6. The first system is built in the human-computer interaction main board 5, and the second system is built in the signal conversion board 6. The first system and the second system are independent systems, and the first system and the second system constitute the dual system of the display screen 31.

[0028] To solve the problem of the reverse of the touch function and the display content, in this embodiment, the first system is selected to be rotated 180 degrees, and then the underlying software control of the signal conversion board 6 is modified to rotate the second system 180 degrees while the HDMI signal does not rotate. When the touch signal of the touch control board 22 is connected to the human-computer interaction main board 5, it will rotate with the rotation of the first system, so as to correspond to the operation interface of the first system on the human-computer interaction main board 5.

[0029] As Figure 1As shown, by default, the touch signal of the touch control panel 22 is connected to the human-computer interaction main board 5. The switch 4 is disconnected from the signal conversion board 6. The human-computer interaction main board 5 provides the human-computer interaction interface and application services, and outputs an HDMI signal to the signal conversion board 6. The HDMI signal is implemented using an HDMI interface. The signal conversion board 6 processes the HDMI signal transmitted by the human-computer interaction main board 5, performs the conversion of the HDMI signal and the processing of the display image quality, and sends it to the TCON board 32. The TCON board 32 drives the display screen 31 to display. At this time, the operation interface of the first system is displayed on the display screen 31, and the first system of the human-computer interaction main board 5 provides display and touch control services.

[0030] As Figure 2 shown, when switching systems, the touch signal of the touch control panel 22 is connected to the signal conversion board 6 through the switch 4, and the switch 4 is disconnected from the human-computer interaction main board 5. At this time, the operation interface of the second system is displayed on the display screen 31. The signal conversion board 6 provides the human-computer interaction interface and application services. At the same time, because the second system of the signal conversion board 6 has been rotated 180 degrees, the touch signal will automatically follow the rotation of the second system without any other operations.

[0031] For the dual-system platform architecture transparent display screen 1 of this embodiment, only the underlying software parameters of the first software system of the signal conversion board 6 need to be modified to control the HDMI signal not to rotate with the system. The workload is small and the cost is low. When switching systems, only the switch 4 needs to be controlled, and it has a good smooth experience during system switching.

[0032] Therefore, compared with the existing switching scheme of the dual-system platform architecture, the dual-system platform architecture transparent display screen 1 of this embodiment does not need to modify the software underlying code of any board card, and can make the operation interface of the software the same as the touch signal, reducing the instability of the software system caused by modifying the software code and reducing the R & D cycle of the software.

[0033] At the same time, it will not cause a problem of accuracy between the touch signal and the software operation interface due to making the operation interface of the software the same as the touch signal by modifying the software underlying code of a certain board card. There is no need to perform the operation of rotating the software system 180 degrees back and forth on a certain board card during dual-system switching, reducing system bugs caused by the back-and-forth rotation of the software, and improving the smoothness and stability during dual-system switching.

[0034] In one embodiment, switching control software buttons (not shown in the figure) are respectively arranged on the operation interfaces of the first system and the second system. The user controls the switch 4 to be connected to the human-computer interaction main board 5 or the signal conversion board 6 by operating the switching control software buttons, so as to facilitate the user to switch back and forth between the two systems.

[0035] Specifically, when the operation interface of the first system is displayed on the display screen 31 and the user operates the switching control software button, the switch 4 receives the first switch signal, connects the switch 4 to the signal conversion board 6 and disconnects it from the human-machine interaction main board 5. At this time, the operation interface of the second system is displayed on the display screen 31. If the user operates the switching control software button on the operation interface of the second system again, the switch 4 receives the second switch signal, connects the switch 4 to the human-machine interaction main board 5 and disconnects it from the signal conversion board 6. At this time, the operation interface of the first system is redisplayed on the display screen 31.

[0036] In this embodiment, the switch 4 has a communication interface (not shown in the figure) and a switching switch module (not shown in the figure). The communication interface is connected to the human-machine interaction main board 5 and is used to receive the switch signal of the human-machine interaction main board 5. The switching switch module is connected to the human-machine interaction main board 5 and the signal conversion board 6. The switching switch module controls the connection with the human-machine interaction main board 5 or the signal conversion board 6 according to the switch signal. The switch 4 receives the switch signal through the communication interface and realizes the switching control based on the software communication interface protocol.

[0037] In this embodiment, refer back to Figure 1 and Figure 2 As shown, the dual-system platform architecture transparent display screen 1 further includes an in-vehicle PIS 7, and the in-vehicle PIS 7 is connected to the human-machine interaction main board 5. The in-vehicle PIS 7 is used to display the in-vehicle system broadcast information on the display screen 31.

[0038] Please refer to Figure 3 and at the same time refer to Figure 1 and Figure 2 , Figure 3 is a schematic flowchart of the steps of the setting method of the dual-system platform architecture transparent display screen according to an embodiment of the present application; as shown in the figure, the setting method S of the dual-system platform architecture transparent display screen includes the following steps S1 to S4. Among them:

[0039] Step S1, install each component. Install the touch component 2, the display screen component 3, the switch 4, the human-machine interaction main board 5 and the signal conversion board 6, wherein the touch screen 21 and the display screen 31 are installed in a flip-chip manner.

[0040] Step S2, rotate the first system. Set the system parameters of the human-machine interaction main board 5 to rotate the first system by 180 degrees. When the touch signal of the touch control board 22 is connected to the human-machine interaction main board 5, it will rotate with the rotation of the first system, so as to correspond to the operation interface of the first system on the display screen 31.

[0041] Step S3: Rotate the second system while keeping the HDMI signal stationary. Set the system parameters of the signal conversion board 6 to rotate the second system by 180 degrees while keeping the HDMI signal stationary. Specifically, modify the underlying software control of the signal conversion board 6 to rotate the second system by 180 degrees while keeping the HDMI signal stationary.

[0042] Step S4: Set the default state. Set the default state of the switch 4 to be connected to the human-machine interaction main board 5. At this time, the human-machine interaction main board 5 provides the human-machine interaction interface and application services, and the operation interface of the first system is displayed on the display screen 31.

[0043] When performing system switching, the user operates the switching control software button on the operation interface of the first system to switch the operation interface of the first system displayed on the display screen 31 to the operation interface of the second system. At this time, the signal conversion board 6 provides the human-machine interaction interface and application services, thus realizing the system switching operation.

[0044] In summary, the present application provides a dual-system platform architecture transparent display screen. The present application only needs to modify the underlying software parameters of the first software system of the signal conversion board to control the HDMI signal not to rotate with its system, with less workload and low cost. During system switching, only the switch needs to be controlled, providing a better smooth experience during system switching.
