The method as claimed in claim 3, wherein if the core board determines that the touch signal is not generated by the first touch screen, the core board sends the display signal and the display position signal to the second display screen, and after receiving the display signal and the display position signal, the second display screen displays the content of the display signal at a position corresponding to the second light-emitting surface of the second display screen.
5. The method as claimed in claim 3 or 4, wherein the board core transmits the display position signal to the dimming controller of the dimming film while transmitting the display signal and the display position signal, and the dimming controller generates and transmits the dimming position signal to the dimming film after receiving the display position signal, and controls the dimming film to perform dimming at the corresponding position.
6. A control method of the double-sided display system with integrated light adjusting film according to any one of claims 1 to 2, comprising the steps of:
when a user touches the first display screen or the second display screen, the corresponding first touch screen or the second touch screen acquires touch position information of the user, generates a touch signal and a touch position signal, and sends the touch signal and the touch position signal to the core board;
after receiving the touch signal and the touch position signal, the core board generates a display signal and a display position signal, and judges whether the touch signal is generated by the first touch screen, if so, the core board judges whether the fed back display content is displayed on the first display screen again, and if so, the core board sends the display signal and the display position signal to the first display screen;
and after the first display screen receives the display signal and the display position signal, displaying the content of the display signal at the position corresponding to the first light-emitting surface of the first display screen.
7. The method as claimed in claim 6, wherein if the core board determines that the fed back display content is not displayed on the first display screen, the core board sends the display signal and the display position signal to the second display screen, and after receiving the display signal and the display position signal, the second display screen displays the content of the display signal at a position corresponding to the second light-emitting surface of the second display screen.
8. The method as claimed in claim 6, wherein if the core board determines that the touch signal is not generated by the first touch screen, the core board determines again whether the fed back display content is displayed on the second display screen, if so, the core board sends the display signal and the display position signal to the second display screen, and after receiving the second display signal and the second display position signal, the second display screen displays the content of the display signal at a position corresponding to the second light emitting surface of the second display screen.
9. The method of claim 8, wherein if the core board determines again that the fed back display content is not displayed on the second display screen, the core board sends the display signal and the display position signal to the first display screen.
10. The method for controlling a system for displaying an integrated light adjusting film on two sides according to any one of claims 6 to 8, wherein the core board transmits the display position signal to the light adjusting film at the same time as the display signal and the display position signal, and the light adjusting controller generates a light adjusting position signal after receiving the display position signal and transmits the light adjusting position signal to the light adjusting film to control the light adjusting film to adjust the light at the corresponding position.
