The two display modules 10 display alternately, and when one display module 10 is in a display mode, the other display module 10 is in a heating mode. The common electrode layer 11 of the display module 10 in the heating mode is reused as a heating electrode.

[0038] In the embodiment of the present application, the common electrode layer 11 in the display module 10 is time-division multiplexed as a heating electrode, without adding an additional heating electrode, and the process is simpler; secondly, the liquid crystal can be heated in a low temperature environment to improve the display speed and display quality of the display panel 100. In addition, the two display modules 10 are displayed alternately, and when one display module 10 is in the display mode, the other display module 10 is in the heating mode, and heating and display can be achieved in the display panel 100 at the same time, which is conducive to improving the display speed of the display module 10.

[0039] The display panel 100 may be a folding screen or a dual screen.

[0040] For example, the embodiment of the present application is described by taking the display panel 100 as a dual screen as an example.

[0041] In each frame, the two display modules 10 are displayed alternately. When one display module 10 is displaying, the other display module 10 is heated, so that the display panel 100 is heated and displayed simultaneously, so as to improve the display speed of the display module 10 .

[0042] The display panel 100 has a display area 101 and a non-display area 102. The non-display area 102 is located at least on one side of the display area 101.

[0043] Exemplarily, the display area 101 is rectangular, and the non-display area 102 is disposed around the display area 101 and is located at four sides of the display area 101 .

[0044] In other embodiments, the display area 101 may be in other shapes such as a circle or an ellipse, which is not restricted here and is selected according to actual needs.

[0046] The two display modules 10 may have different shapes and / or different sizes; or, the two display modules 10 may have the same shape and size. No excessive restrictions are imposed here and the selection is made according to actual conditions.

[0047] Exemplarily, the two display modules 10 have the same shape and size. The display module 10 is rectangular, and the two display modules 10 are arranged side by side.

[0048] The display area 101 includes a first display area 101A and a second display area 101B, each of which is used to set two display modules 10. The two display modules 10 are respectively a first display module 10A and a second display module 10B.

For example, the common electrode layer 11 in one display module 10 is the common electrode layer 11 in the color filter substrate, and the common electrode layer 11 in the other display module 10 is the common electrode layer 11 in the array substrate. That is, when one display module 10 is in the heating mode, the common electrode layer on the color filter substrate side corresponding to the display module 10 is reused as a heating electrode, and when the other display module 10 is in the heating mode, the common electrode layer on the array substrate side corresponding to the display module 10 is reused as a heating electrode.

Multiple common electrode layers 11 are insulated so that each common electrode layer 11 can be independently controlled, or the common electrode layer 11 is composed of multiple sub-common electrode layers (not shown) electrically connected to each other. The sub-common electrode layer can be in the shape of an arch, a bar, etc., which is not limited here and can be selected according to actual needs.

[0061] The shapes of the plurality of common electrode layers 11 are different, and / or the sizes of the plurality of common electrode layers 11 are different; or, the shapes and sizes of the plurality of common electrode layers 11 are the same.

[0070] In some embodiments, in the heating mode, one end of the corresponding common electrode layer 11 is coupled to a heating signal line 30 and the other end is coupled to another heating signal line 30 to form a closed loop and reuse the corresponding common electrode layer 11 as a heating electrode.

[0071] Specifically, each common electrode layer 11 is electrically connected to two heating signal lines 30 , respectively, and a heating signal is provided through the heating signal lines 30 .

[0072] In a specific embodiment, there are three heating signal lines 30, namely, a first heating signal line 31, a second heating signal line 32 and a third heating signal line 33.

[0076] At least one electrical connection point 50 is provided between the third heating signal line 33 and the corresponding common electrode layer 11, so that the current distribution on the corresponding common electrode layer 11 is more uniform, thereby achieving uniform heating of the liquid crystal. Similarly, there may be at least one electrical connection point 50 between the portion of the first heating signal line 31 located on the side of the first display module 10A away from the second display module 10B and the corresponding common electrode layer 11, and there may be at least one electrical connection point 50 between the portion of the second heating signal line 32 located on the side of the second display module 10B away from the first display module 10A and the corresponding common electrode layer 11.

The heating switch S1 between the heating signal line 30 and the first common electrode layer 111 is turned off to stop transmitting the heating signal to the first common electrode layer 111. The common switch S2 between the second common signal line 22 and the external control module is turned on, and the common voltage signal is multiplexed as a heating signal and transmitted to the second common electrode layer 112. The heating switch S1 between the heating signal line 30 and the second common electrode layer 112 is turned on to transmit the heating signal to the second common electrode layer 112.

[0099] On the contrary, when the first display module 10A is in the heating mode and the second display module 10B is in the display mode, the common switch S2 between the first common signal line 21 and the external control module is turned on, and the common voltage signal is multiplexed into a heating signal and transmitted to the first common electrode layer 111.

[0100] In some embodiments, the display module 10 further includes a plurality of data lines 40 and a plurality of scan lines (not shown), the data lines 40 are located in the display area 101, and each data line 40 includes a first portion 41 and a second portion 42, the first portion 41 is used to provide a data voltage signal for one display module 10, and the second portion 42 is used to provide a data voltage signal for another display module 10. The plurality of scan lines are located in the display area 101, and are arranged in sequence along the arrangement direction of the two display modules 10. In each frame, the two display modules 10 are displayed alternately.

[0101] The display panel 100 further includes a data switch S3, which is connected between the data line 40 and the external control module. Specifically, a data switch S3 is provided between the first part 41 and the external control module, and a data switch S3 is provided between the second part 42 and the external control module. The first part 41 and the second part 42 are independently controlled to realize the alternating display of the two display modules 10.

[0102] There is no restriction on the scanning mode of the scanning line here, and it can be selected according to actual needs.

[0103] Exemplarily, the scan lines are driven row by row to realize the alternating display of the two display modules 10 in each frame. For example, there are N scan lines, which are scanned row by row from the first row to the Nth row of scan lines. The first N / 2 scan lines are used to drive the first display module 10A to display, and the last N / 2 scan lines are used to drive the second display module 10B to display. In the process of scanning the first N / 2 scan lines row by row, the second display module 10B is in the heating mode. When scanning to the N / 2+1th scan line, the first display module 10A is in the heating mode, and the last N / 2 scan lines are scanned row by row to put the second display module 10B in the display mode, so as to realize the alternating display of the two display modules 10 in each frame.

[0104] In the embodiment of the present application, the heating signal line 30, the common signal line 20 and the data line 40 are independently controlled to avoid mutual influence between the heating signal, the common voltage signal and the data voltage signal, thereby achieving simultaneous driving of heating and displaying of the display panel 100.
