Because the power supply equipment and the electric device are in inductive coupling to transfer energy, and the power supply equipment and the electric device are not connected by wires, the wireless charging technology improves the charging safety on one hand, and on the other hand, the electric device is not bound by tangible wires, so that the use convenience of a user is improved. Currently, wireless charging technology has been widely applied to various electronic display devices (e.g., mobile phones, computers, etc.).

The related art generally adopts an improvement method to enhance the driving capability of the data line, so that the interference of the wireless charging signal is weakened, but such an improvement method brings about a problem of increasing power consumption.

It should be noted that, in the present embodiment, the setting position and the setting structure of the wireless charging component 20 are not specifically limited, the wireless charging component 20 is only illustrated by a frame in fig. 1, and the actual structure of the wireless charging component 20 is not shown, in a specific implementation, the setting position of the wireless charging component 20 may be set on one side of the display panel 00 (for example, the backlight side of the display panel 00) illustrated in fig. 1, and the wireless charging driving circuit 302 on the other side of the display panel 00 is electrically connected by punching a film layer structure of the display panel 00, or may be in another setting structure, fig. 1 of the present embodiment merely illustrates an electrical connection relationship between the two by way of example, and does not show an actual setting structure.

It can be understood that fig. 1 and fig. 3 of the present embodiment are only block diagrams illustrating the display driving circuit 301 and the wireless charging driving circuit 302 in the driving circuit 30, and do not show an actual design structure of the driving circuit 30, and the driving circuit 30 may include an electrical connection structure such as a transistor or a capacitor, etc. for implementing provision and transmission of a driving signal, which is not specifically limited in this embodiment, and in specific implementation, it can be understood by referring to the structures of the display driving circuit 301 and the wireless charging driving circuit 302 in the related art, the display driving circuit 301 of the present embodiment only needs to be capable of providing a display driving signal for the display unit 10 to implement a display effect of the display panel 00, and the wireless charging driving circuit 302 only needs to be capable of providing a charging signal for the wireless charging component 20 to implement charging for the display device.

In some alternative embodiments, please refer to fig. 1 and fig. 4 in combination, fig. 4 is another timing diagram of the display apparatus in fig. 1 during operation, in which in the embodiment, the first time period T1 is a frame time, and the second time period T2 is located between two adjacent frame times.

This embodiment explains that the display driving signal provided to the display unit 10 by only the display driving circuit 301, and the first time period T1 when the wireless charging driving circuit 302 stops providing the charging signal to the wireless charging assembly 20 may be a Frame time, i.e. 1Frame, where one Frame refers to a still image, and one Frame time refers to a time required for completing displaying of a still image, and in this embodiment, it can be understood that in a Frame time, the scanning driving circuit completes the activation of each scanning line G, opens each row of display units 10 row by row, the data driving circuit completes the process of writing the data voltage signal to each data line S and transmitting the data voltage signal to each display unit 10 through the data line S, and the second time period T2 is located between two adjacent Frame times, for example, the first Frame display image completes and then enters the wireless charging operation of the second time period T2, and entering a second frame display picture after the wireless charging work of the second time period T2 is completed. Assuming that the display panel 00 of the display device 000 of the embodiment includes 100 rows of display units 10, in the first Frame (1Frame), the scan driving circuit completes turning on all the scan lines G, opens each display unit 10 in 100 rows one by one, and completes writing the data voltage signal to each data line S through the data driving circuit, after the data line S transmits the data voltage signal to the 100 rows of display units 10, the first Frame (1Frame) finishes the screen refresh, waits for a period of time, for example, the period of time for scanning 50 rows of display units 10, which is the second period of time T2 (corresponding to the period of time for adding one Hold Frame), the wireless charging driving circuit 302 only provides the charging signal to the wireless charging component 20 for wireless charging in the second period of time T2, and in the second period of time T2, the display driving circuit 301 of the scan driving circuit or the data driving circuit stops providing the display driving signal to the display units 10, and after the second time period T2 is finished, continuing the second Frame (2Frame), displaying the picture of the next Frame, and so on. In this embodiment, the charging time period in which the wireless charging driving circuit 302 provides the charging signal to the wireless charging assembly 20 is set between two adjacent frames, so that the display time period can be better avoided, and the time period in which the display driving circuit 301 provides the display driving signal to the display unit 10 and the charging time period in which the wireless charging driving circuit 302 provides the charging signal to the wireless charging assembly 20 are completely not overlapped, which not only can better avoid the interference of the wireless charging assembly 20 on the display effect of the display panel 00 during operation, but also does not need to change the driving time sequence of one frame set by the display panel 00 itself, and only needs to add the waiting time between two adjacent frames for wireless charging, and the change of the driving time sequence of the display device 000 is small, which is beneficial to improving the process efficiency and saving the cost.

In some optional embodiments, please refer to fig. 5 and fig. 6 in combination, where fig. 5 is another schematic plane structure diagram of a display device according to an embodiment of the present invention (it can be understood that fig. 5 is filled with transparency to clearly illustrate the structure of the wireless charging component in this embodiment), fig. 6 is a timing diagram of the display device in fig. 5 when operating, in this embodiment, the display panel 00 includes a display area AA, and the display area AA is included in the display panel 00 for a frame time T_FIn the inside, the display area AA includes an effective screen display area AA1 and a non-effective screen display area AA 2; one frame time T_FIncluding a non-effective picture display period T_F2And an effective picture display period T_F1；

First time period T1 and effective picture display time period T_F1Overlapping, the second period T2 and the non-effective picture display period T_F2Overlap.

Alternatively, as shown in fig. 5, the plurality of display units 10 are sequentially arranged along the first direction X to form a display unit row 10H, and the plurality of display unit rows 10H are arranged along the second direction Y; wherein the first direction X and the second direction Y intersect; it is understood that the first direction X and the second direction Y are perpendicular to each other in the direction of the light exit surface of the display device 000 in the present embodiment.

In the non-effective picture display period T_F2In this case, the display driving circuit 301 does not provide a display driving signal to at least the nth display cell row 10H, and the area where the nth display cell row 10H is located is the inactive screen display area AA 2. Or in the non-effective picture display period T_F2In this embodiment, the display driving circuit 301 may not provide the display driving signal to the plurality of display cell rows 10H, that is, the display driving circuit 301 may not provide the display driving signal to the 1 st to nth display cell rows 10H, where the area where the 1 st to nth display cell rows 10H are located is the non-effective picture display area AA2, where n may be any positive integer smaller than the total number of rows of display cell rows 10H included in the display panel 00, and this embodiment is not limited thereto.

The present embodiment explains that the first period T1 of the display driving signal supplied from the display driving circuit 301 to the display unit 10 and the second period T2 of the charging signal supplied from the wireless charging driving circuit 302 to the wireless charging component 20 may be located at one frame time T_FIn one frame time T_FI.e. 1Frame, one Frame refers to a still picture, and one Frame time T_FRefers to the time required for completing the display of a still picture, which in this embodiment is understood to be the time of one frame time T_FIn the meantime, the scan driving circuit turns on each scan line G, and turns on each row of the display units 10 line by line, and the data driving circuit completes a process of writing a data voltage signal into each data line S and transmitting the data voltage signal to each display unit 10 through the data line S. In the process of displaying one frame of picture, the display area AA of the display panel 00 may be set to include at least one effective picture display area AA1 and at least one non-effective picture display area AA2, where the effective picture display area AA1 may be understood as an area in which each display unit 10 of the area displays a substantial picture after writing a display driving signal, such as a necessary signal of time and date, and the non-effective picture display area AA2 may be understood as an area without a substantial picture, such as the non-effective picture display area AA2 of a black picture, in which each display unit 10 does not write a display driving signal in some non-necessary display areas AA ranges in order to save the driving power consumption of the display panel 00.
