[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In one embodiment of the present application, please refer to Figure 1 , which is a schematic diagram of a transparent display window based on a double-sided display function according to an embodiment of the present application; as shown in the figure, the transparent display window 1 based on the double-sided display function includes a window body 2, a transparent display screen 3 and an electric rolling shutter film 4. In this embodiment, the window body 2 includes an outer glass 21, a spacer 22 and an inner glass 23. The spacer 22 is arranged on the inner edge of the outer glass 21, and the inner glass 23 is arranged on the spacer 22. A hollow layer 24 is formed between the inner glass 23 and the outer glass 21 and the spacer 22. The window body 2 is mainly used to be installed on the side window frame of the train. The outer glass 21 is located on the outside of the train, and the inner glass 23 is located on the inside of the train. In this embodiment, the window body 2 also includes a shielding layer 25, and the shielding layer 25 is arranged on the inner glass 23. The shielding layer 25 is made of black ink, which is printed on the side of the inner glass 23 facing the transparent display screen 3 by screen printing, such as Figure 1 As shown, the shielding layer 25 is located at the upper end of the outer side of the inner glass 23 .

[0028] See also Figure 1 The transparent display screen 3 is arranged on the outer glass 21 and is located in the hollow layer 24. In this embodiment, the vehicle window body 2 further includes a laminated layer 26. The transparent display screen 3 is arranged on the outer glass 21 through the laminated layer 26. Specifically, one side of the laminated layer 26 is laminated to the outer glass 21, and the transparent display screen 3 is laminated to the other side of the laminated layer 26. The outer glass 21, the transparent display screen 3 and the laminated layer 26 are laminated together through a laminated process. The transparent display screen 3 is a transparent OELD screen, but is not limited thereto.

[0029] See also Figure 2, which is a schematic diagram of a transparent display screen of an embodiment of the present application; as shown in the figure, the display surface 31 of the transparent display screen 3 faces the inner side of the window body 2, and the display surface 31 has a first display area 311 and a second display area 312, that is, the first display area 311 and the second display area 312 are both displayed toward the inside of the train. The first display area 311 is opposite to the shielding layer 25, and the shielding layer 25 blocks the picture displayed by the first display area 311, so that the picture displayed by the first display area 311 cannot be seen from the inside of the train. The pictures displayed by the first display area 311 and the second display area 312 are independent of each other, so that the first display area 311 and the second display area 312 display different pictures. The display picture of the first display area 311 is a picture after mirror inversion, and the display picture of the second display area 312 is a normal picture. In this embodiment, the picture after mirror inversion is a dynamic map picture. The normal picture includes but is not limited to train travel information, advertisements and entertainment videos, such as Figure 2 As shown, the first display area 311 and the second display area 312 are both rectangular, the first display area 311 is located at the upper end of the second display area 312, and the area of ​​the first display area 311 is smaller than that of the second display area 312, but not limited thereto.

[0030] See also Figure 1 The electric rolling shutter film 4 is arranged in the hollow layer 24 and is located between the transparent display screen 3 and the inner glass 23. Figure 1 As shown, the electric rolling curtain film 4 is arranged on the spacer 22, and the electric rolling curtain film 4 is located in the shielding area of ​​the shielding layer 25. The electric rolling curtain film 4 is arranged to be unfolded or retracted in a rolling curtain manner. In this embodiment, the electric rolling curtain film 4 is a fully reflective flexible material film, which is unfolded and retracted in a rolling curtain manner through motor control. When the electric rolling curtain film 4 is unfolded, the electric rolling curtain film 4 is opposite to the first display area 311 to reflect the picture displayed in the first display area 311, so that it overlaps with the original picture, enhances the display, and enables the picture to be displayed through the back of the first display area 31.

[0031] When the transparent display window 1 based on the double-sided display function of this embodiment is used on a train, the window body 2 is installed on the side window frame of the train, the electric roller shutter film 4 is linked with the train sequence, and the second display area 312 displays a normal picture toward the inside of the train. In a specific time period, such as when the train enters the station or when the train stops at a station, the first display area 311 displays a mirror-reversed picture toward the inside of the train, which is a mirror-image PIS dynamic map picture. The electric roller shutter film 4 is in an unfolded state and opposite to the first display area 311. The electric roller shutter film 4 reflects the mirror-image PIS dynamic map picture so that it overlaps with the original picture in the first display area 311 to enhance the display, so that the picture can be displayed through the back of the first display area 311 and it is a positive PIS dynamic map picture, so that the PIS dynamic map is displayed outside the train. At this time, the back of the first display area 311 of the transparent display screen 3 is displayed to the outside, and the second display area 312 is displayed to the inside, so that the double-sided display function of the transparent display screen is realized, and the area of ​​the transparent display screen 3 shielded by the black ink area can be fully utilized to improve the utilization rate of the transparent display screen 3.

[0032] In the second embodiment of this application, please refer to Figure 3 , which is a schematic flow chart of the steps of the timing control method of the transparent display window based on the double-sided display function in the second embodiment of the present application; as shown in the figure, the timing control method S of this embodiment is the timing control of the transparent display window 1 based on the double-sided display function in the above-mentioned first embodiment, and the transparent display window 1 is arranged in the passenger compartment of the train. The timing control method S of the transparent display window based on the double-sided display function includes the following steps S1-S3, wherein:

[0033] Step S1, generating and sending dynamic map display information. The host generates dynamic map display information and sends the dynamic map display information to the passenger compartment switch in the passenger compartment through the vehicle Ethernet bus.

[0034] Specifically, when a dynamic map needs to be displayed during a specific time period, such as when a train enters or exits a platform or stops at a station, the host in the train driver's cab generates dynamic map display information and sends the dynamic map display information to the passenger compartment switch in the passenger compartment via the on-board Ethernet bus.

[0035] Step S2, allocating dynamic map display information. The passenger compartment switch allocates the dynamic map display information and transmits it to the main control board of each transparent display window 1 in the passenger compartment through Ethernet.

[0036] Specifically, the passenger compartment of the train usually has multiple transparent display windows 1, which are electrically connected to the passenger compartment switch. After the passenger compartment switch receives the dynamic map display information, it distributes it and then transmits it to the main control board of each transparent display window 1 in the passenger compartment via Ethernet.

[0037] Step S3, displaying the dynamic map display information outside the train. The main control board of each transparent display window 1 processes the dynamic map display information, so that the transparent display screen 3 displays the dynamic map display information outside the train.

[0038] For details, please refer to Figure 4 , which is Figure 3 Schematic diagram of a specific implementation example of step S3; as shown in the figure, after receiving the dynamic map display information, the main control board of each transparent display window 1 executes step S31 to process the dynamic map display information and processes the dynamic map display information into a mirrored dynamic map picture; then executes steps S32 and S33, in which the main control board drives the transparent display screen 3 to display in partitions, and divides the display surface 31 of the transparent display screen 3 into a first display area 311 and a second display area 312, and the pictures displayed in the first display area 311 and the second display area 312 are displayed independently of each other; in step S33, the main control board controls the first display area 311 to display the mirrored dynamic map picture.

[0039] While executing step S32 and step S33, step S34 and step S35 are also executed. In step S34, the main control board sends a signal to the controller of the electric roller shutter film 4, which is a signal for starting the drive control, or a signal for driving the motor to rotate. In step S35, the controller controls the electric roller shutter film 4 to unfold. At this time, the electric roller shutter film 4 is in an unfolded state and opposite to the first display area 311. The electric roller shutter film 4 reflects the mirrored dynamic map display information displayed in the first display area 311, so that it overlaps with the original mirror image in the first display area 311 to enhance the display, so that the positive dynamic map display information can be displayed through the back of the first display area 311, and step S36 is implemented to display the dynamic map image outside the train. In this way, the train operation line information, station announcement information, door opening side information, time information, etc. are intuitively displayed to passengers through a graphical interface, which effectively increases the utilization rate of display resources, increases product functions, and enhances the effective value of the product.

[0040] In summary, the present application provides a transparent display window based on a double-sided display function and a timing control method thereof. The present application provides a transparent display window based on a double-sided display function, in which an electric roller shutter film is arranged between the transparent display screen and the inner glass, and the display surface of the transparent display screen is divided into a first display area and a second display area. When the electric roller shutter film is unfolded, the electric roller shutter film is opposite to the first display area, and reflects the picture displayed in the first display area, so that the reflected picture overlaps with the picture displayed in the first display area to enhance the display, so that the picture can be displayed through the back of the first display area, so that the back of the first display area is displayed to the outside, and the second display area is displayed to the inside, so as to realize the double-sided display function of the transparent display screen.

[0041] The present application is based on a timing control method for transparent display windows with a double-sided display function. Dynamic map display information is generated by a host computer, and information is transmitted through an on-board Ethernet, so that the transparent display screen of each transparent display window displays the dynamic map display information toward the outside of the train, so that the train can display the content of the PIS dynamic map through the transparent display screen of the window at specific times such as entering and exiting a station, stopping at a station, etc. The dynamic map display intuitively displays train route information, station announcement information, door opening side information, time information, etc. to passengers through a graphical interface, effectively increasing the utilization rate of display resources, increasing product functions, and improving the effective value of the product.
