Description

[Technical Field]

[0001] This application relates to the field of display technology, and in particular to a display panel and its driving method, and a display device. [Background Technology]

[0002] With the continuous development of science and technology, electronic display devices are becoming increasingly inseparable from people's lives. Electronic display devices such as computers, mobile phones, and in-vehicle displays have become indispensable tools for people's work and life. Among them, the display panel used to display images is an important component of electronic display devices.

[0003] However, in existing technologies, display panels typically consume high power, especially as the resolution and pixel integration of display panels continue to improve image quality. High power consumption has become a significant constraint on the development of display panels. Therefore, a solution to reduce display panel power consumption is urgently needed.

[0004] [Application Content]

[0005] In view of this, embodiments of this application provide a display panel and its driving method, as well as a display device, to solve the above problems.

[0006] In a first aspect, embodiments of this application provide a display panel, including multiple sub-pixel rows and multiple sub-pixel columns, a scanning unit, and a multiplexing unit; the multiple sub-pixel rows include a first sub-pixel row and a second sub-pixel row, and the multiple sub-pixel columns include a first sub-pixel column and a second sub-pixel column; the scanning unit includes multiple scanning output terminals, each used to transmit scanning signals to a sub-pixel row, including a first scanning output terminal and a second scanning output terminal, the first scanning output terminal being electrically connected to a first sub-pixel row, and the second scanning output terminal being electrically connected to a second sub-pixel row; the multiplexing unit is used to transmit data signals to a sub-pixel column, and the multiplexing unit includes a first multiplexing unit and a second multiplexing unit, the first multiplexing unit being electrically connected to a first sub-pixel column, and the second multiplexing unit being electrically connected to a second sub-pixel column; in one frame of the display panel, one of the first scanning output terminal and the second scanning output terminal does not output a valid scanning signal, and / or, one of the first multiplexing unit and the second multiplexing unit is turned off.

[0007] Secondly, embodiments of this application provide a driving method for a display panel, used to drive the display panel as provided in the first aspect. The display panel includes a first driving mode and a second driving mode. The driving method includes:

[0008] In the first driving mode, in one frame of the display panel, both the first scan output terminal and the second scan output terminal output valid scan signals, and in the first multiplexing unit and the second multiplexing unit, one is turned on and the other is turned off.

[0009] In the second driving mode, in one frame of the display panel, both the first multiplexing unit and the second multiplexing unit are turned on, and in the first scan output terminal and the second scan output terminal, one outputs a valid scan signal and the other does not output a valid scan signal.

[0010] Thirdly, embodiments of this application provide a display device, including a display panel as provided in the first aspect.

[0011] In this embodiment of the application, in a frame of the display panel, if one of the first scan output terminal and the second scan output terminal is set not to output a valid scan signal, and / or one of the first multiplexing unit and the second multiplexing unit is turned off, then some sub-pixel rows and / or some sub-pixel columns do not need to refresh the display data, which helps to reduce the power consumption of the display panel.

[0012] Furthermore, in a single frame of a display panel, since the display of some sub-pixel rows or columns can remain unchanged, it also helps to reduce the flickering of the display and improve the quality of the display. [Attached Image Description]

Detailed Implementation Methods

[0027] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0029] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0030] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0031] In the description of this specification, it should be understood that the terms "substantially", "approximately", "about", "about", "generally", "largely" used in the claims and embodiments of this application refer to values ​​that can be generally agreed upon within a reasonable range of process operations or tolerances, rather than a precise value.

[0032] It should be understood that although terms such as "first," "second," etc., may be used in the embodiments of this application to describe driving modes, subpixel rows, subpixel columns, multiplexing units, scanning units, scanning output terminals, etc., these driving modes, subpixel rows, subpixel columns, multiplexing units, scanning units, scanning output terminals, etc., should not be limited to these terms. These terms are only used to distinguish driving modes, subpixel rows, subpixel columns, multiplexing units, scanning units, scanning output terminals, etc., from each other. For example, without departing from the scope of the embodiments of this application, the first driving mode may also be referred to as the second driving mode, and similarly, the second driving mode may also be referred to as the first driving mode.

[0033] In the field of display technology, the pixel array of a display panel typically includes multiple rows of grid lines and multiple columns of data lines intersecting the grid lines. When displaying a frame, a scanning unit including a shift register typically provides scanning signals to the multiple rows of grid lines of the pixel array, thereby controlling the multiple rows of grid lines to transmit valid scanning signals sequentially, and at the same time, data lines provide data signals to the pixel units in the corresponding rows of the pixel array.

[0034] In related technologies, the driving method used by the display panel is usually as follows: during one frame of the display panel, each row of grid lines is scanned sequentially starting from the first row of grid lines, and at the same time, data signals are sequentially provided to the pixel units of the corresponding row in the pixel array by the data lines to complete the display of one frame.

[0035] However, display panels using the above driving method have high power consumption, which is not conducive to the development of display panels.

[0036] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0037] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of this application. Figure 2 This is a schematic diagram of yet another display panel provided in an embodiment of this application. Figure 3 This is a schematic diagram of a multiplexing unit provided in an embodiment of this application.

[0038] This application embodiment provides a display panel 01, such as Figure 1 and Figure 2As shown, the display panel 01 includes multiple subpixel rows 11 and multiple subpixel columns 12, and each subpixel row 11 and each subpixel column 12 includes multiple subpixels 10. The multiple subpixel rows 11 include a first subpixel row 111 and a second subpixel row 112, and the multiple subpixel columns 12 include a first subpixel column 121 and a second subpixel column 122.

[0039] Optionally, the first subpixel row 111 is an odd-numbered row of subpixels in the display panel 01, and the second subpixel row 112 is an even-numbered row of subpixels in the display panel 01; and the first subpixel column 121 is an odd-numbered column of subpixels in the display panel 01, and the second subpixel column 122 is an even-numbered column of subpixels in the display panel 01.

[0040] The display panel 01 also includes a scanning unit 20 and a multiplexing unit 30. The scanning unit 20 includes multiple scanning output terminals Po, which are used to transmit scanning signals to the sub-pixel row 11. Among the multiple scanning output terminals Po, there is a first scanning output terminal Po1 and a second scanning output terminal Po2. The first scanning output terminal Po1 is electrically connected to the first sub-pixel row 111, and the second scanning output terminal Po2 is electrically connected to the second sub-pixel row 112. That is, the first scanning output terminal Po1 can be used to transmit scanning signals to the first sub-pixel row 111, and the second scanning output terminal Po2 can be used to transmit scanning signals to the second sub-pixel row 112.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the display panel 01 includes a display area AA and a peripheral area NA surrounding the display area AA. Sub-pixels 10 are located in the display area AA, and scanning units 20 are located in the peripheral area NA. The scanning output terminals Po of the scanning units 20 are located on opposite sides of the display area AA.

[0042] Optionally, such as Figure 1 As shown, the first scan output terminal Po1 and the second scan output terminal Po2 are located on opposite sides of the display area AA. That is, the first scan output terminal Po1 is located on one side of the display area AA, and the second scan output terminal Po2 is located on the other side of the display area AA.

[0043] Optionally, such as Figure 2 As shown, a first scan output terminal Po1 and a second scan output terminal Po2 are provided on both sides of the display area AA.

[0044] The multiplexing unit 30 is used to transmit data signals to the sub-pixel column 12. The multiplexing unit 30 includes a first multiplexing unit 31 and a second multiplexing unit 32. The first multiplexing unit 31 is electrically connected to the first sub-pixel column 121, and the second multiplexing unit 32 is electrically connected to the second sub-pixel column 122. That is, the first multiplexing unit 31 can be used to transmit data signals to the first sub-pixel column 121, and the second multiplexing unit 32 can be used to transmit data signals to the second sub-pixel column 122. Of course, multiple first multiplexing units 31 and multiple second multiplexing units 32 can be provided in the display panel 01.

[0045] For example, combined Figure 1 and Figure 3 As shown, the first multiplexing unit 31 includes one input terminal 31A and three output terminals 31B. The input terminal 31A of the first multiplexing unit 31 is electrically connected to the first data signal terminal 41, and the three output terminals 31B are respectively electrically connected to different first sub-pixel columns 121. The first multiplexing unit 31 includes a first selection switch KH1, a second selection switch KH2, and a third selection switch KH3. The first poles of the first selection switches KH1, KH2, and KH3 are electrically connected and electrically connected to the input terminal 31A of the first multiplexing unit 31. The second poles of the first selection switches KH1, KH2, and KH3 are respectively electrically connected to the output terminals 31B of the first multiplexing unit 31. The control terminal of the first selection switch KH1 is electrically connected to the first control signal line SR1, the control terminal of the second selection switch KH2 is electrically connected to the second control signal line SR2, and the control terminal of the third selection switch KH3 is electrically connected to the third control signal line SR3.

[0046] The second multiplexing unit 32 includes one input terminal 32A and three output terminals 32B. The input terminal 32A is electrically connected to the second data signal terminal 42, and the three output terminals 32B are respectively electrically connected to different second sub-pixel columns 122. The second multiplexing unit 32 includes a fourth selection switch KH4, a fifth selection switch KH5, and a sixth selection switch KH6. The first terminals of the fourth, fifth, and sixth selection switches KH4 and KH5 are electrically connected to the input terminal 32A of the second multiplexing unit 32, and the second terminals of the fourth, fifth, and sixth selection switches KH6 are respectively electrically connected to the output terminals 32B of the second multiplexing unit 32. Specifically, the control terminal of the fourth selection switch KH4 is electrically connected to the fourth control signal line SR4, the control terminal of the fifth selection switch KH5 is electrically connected to the fifth control signal line SR5, and the control terminal of the sixth selection switch KH6 is electrically connected to the sixth control signal line SR6. It should be noted that... Figure 3The illustration only shows the case where the first selector switch KH1, the second selector switch KH2, the third selector switch KH3, the fourth selector switch KH4, the fifth selector switch KH5, and the sixth selector switch KH6 are all N-type transistors. Of course, any one of them could also be a P-type transistor.

[0047] It should be noted that, Figures 1-3 This illustration only shows the case where the multiplexing unit 30 includes three outputs. In some other embodiments, the multiplexing unit 30 may also include more than three outputs.

[0048] In one frame of the display panel, one of the first scan output terminal Po1 and the second scan output terminal Po2 does not output a valid scan signal, and / or one of the first multiplexing unit 31 and the second multiplexing unit 32 is turned off.

[0049] In other words, within one frame of the display panel, either the first scan output terminal Po1 or the second scan output terminal Po2 can be set to not output a valid scan signal; or either the first multiplexing unit 31 or the second multiplexing unit 32 can be set to be turned off; or either the first scan output terminal Po1 or the second scan output terminal Po2 can be set to not output a valid scan signal, and either the first multiplexing unit 31 or the second multiplexing unit 32 can be turned off.

[0050] It is understandable that, in a frame of the display panel, if one of the first scan output terminal Po1 and the second scan output terminal Po2 is set not to output a valid scan signal, then the first sub-pixel row 111 or the second sub-pixel row 112 can stop refreshing the display data; if one of the first multiplexing unit 31 and the second multiplexing unit 32 is turned off, then the first sub-pixel column 121 or the second sub-pixel column 122 can stop refreshing the display data. The valid scan signal referred to here is the transistor in sub-pixel row 11 that receives the valid scan signal after the first scan output terminal Po1 or the second scan output terminal Po2 transmits the valid scan signal to sub-pixel row 11. In this embodiment, the valid scan signal output by the first scan output terminal Po1 and the second scan output terminal Po2 can be a high-level signal.

[0051] In this embodiment, in a frame of the display panel 01, if one of the first scan output terminal Po1 and the second scan output terminal Po2 is set not to output a valid scan signal, and / or one of the first multiplexing unit 31 and the second multiplexing unit 32 is turned off, then some sub-pixel rows 11 and / or some sub-pixel columns 12 do not need to refresh the display data, which helps to reduce the power consumption of the display panel.

[0052] Furthermore, in a single frame of the display panel 01, since the display of some sub-pixel rows 11 or sub-pixel columns 12 can remain unchanged, it is also beneficial to reduce the flickering of the display and improve the quality of the display.

[0053] Figure 4 This application provides a timing diagram of the driving mode of a display panel in a first driving mode. Figure 5 This is a driving timing diagram of a display panel in a second driving mode, provided as an embodiment of this application.

[0054] In one embodiment of this application, the display panel 01 includes a first driving mode and a second driving mode. In the first driving mode, in a frame of the display panel 01, both the first scan output terminal Po1 and the second scan output terminal Po2 output valid scan signals, and in the first multiplexing unit 31 and the second multiplexing unit 32, one is turned on and the other is turned off.

[0055] For example, combining Figures 2-4 As shown, in a frame(n) of the display panel 01, both the first scan output terminal Po1 and the second scan output terminal Po2 output valid scan signals, and the first multiplexing unit 31 is turned on and the second multiplexing unit 32 is turned off.

[0056] In the second driving mode, in one frame of the display panel 01, both the first multiplexing unit 31 and the second multiplexing unit 32 are turned on, and in the first scan output terminal Po1 and the second scan output terminal Po2, one outputs a valid scan signal and the other does not output a valid scan signal.

[0057] For example, combining Figure 2 , Figure 3 and Figure 5 As shown, in a frame(n) of the display panel 01, both the first multiplexing unit 31 and the second multiplexing unit 32 are turned on and transmit data signals, and the first scan output terminal Po1 outputs a valid scan signal, while the second scan output terminal Po2 does not output a valid scan signal.

[0058] In this embodiment of the application, in the first driving mode, in a frame(n) of the display panel 01, the first scan output terminal Po1 and the second scan output terminal Po2 can scan the first sub-pixel row 111 and the second sub-pixel row 112 line by line. However, only the first multiplexing unit 31 can transmit data signals to the first sub-pixel column 121, or only the second multiplexing unit 32 can transmit data signals to the second sub-pixel column 122. That is, in a frame, there may be a situation where the first sub-pixel column 121 or the second sub-pixel column 122 does not need to refresh the display data, which helps to reduce the power consumption of the display panel 01.

[0059] In the second driving mode, within a frame(n) of the display panel 01, the first multiplexing unit 31 and the second multiplexing unit 32 can transmit data signals to different sub-pixel columns 12 respectively. However, only the first sub-pixel row 111 or only the second sub-pixel row 112 receives a valid scan signal. That is, within a frame, there may be instances where the first sub-pixel row 111 or the second sub-pixel row 112 does not need to refresh the display data, thereby helping to reduce the power consumption of the display panel 01.

[0060] Figure 6 This is a schematic diagram of another display panel provided in an embodiment of this application.

[0061] In one technical solution of this application embodiment, please continue to refer to Figure 1 The scanning unit 20 includes a first scanning unit 21 and a second scanning unit 22. The first scanning unit 21 and the second scanning unit 22 are located on opposite sides of the sub-pixel row 11, respectively. The first scanning unit 21 includes a first scanning output terminal Po1, and the second scanning unit 22 includes a second scanning output terminal Po2.

[0062] In the first driving mode, in a frame of the display panel 01, the first scan output terminal Po1 of the first scan unit 21 and the second scan output terminal Po2 of the second scan unit 22 both output valid scan signals.

[0063] In the second driving mode, in one frame of the display panel 01, one of the first scanning unit 21 and the second scanning unit 22 outputs a valid scanning signal, while the other does not output a valid scanning signal.

[0064] Furthermore, in the second driving mode, in one frame of the display panel 01, the first scan output terminal Po1 of the first scan unit 21 or the second scan output terminal Po2 of the second scan unit 22 outputs a valid scan signal. That is, in the second driving mode, in one frame of the display panel 01, only the first scan output terminal Po1 of the first scan unit 21 transmits a scan signal to the first sub-pixel row 111, or only the second scan output terminal Po2 of the second scan unit 22 transmits a scan signal to the second sub-pixel row 112.

[0065] Specifically, such as Figure 6 As shown, the first scanning unit 21 includes a first shift register 211. The output terminal of the first shift register 211 is electrically connected to the first scanning output terminal Po1 of the first scanning unit 21, that is, the output terminal of the first shift register 211 is electrically connected to the first sub-pixel row 111. The first shift register 211 transmits scanning signals to the first sub-pixel row 111.

[0066] The second scanning unit 22 includes a second shift register 221. The output terminal of the second shift register 221 is electrically connected to the second scanning output terminal Po2 of the second scanning unit 22, that is, the output terminal of the second shift register 221 is electrically connected to the second sub-pixel row 112, and the second shift register 221 transmits scanning signals to the second sub-pixel row 112.

[0067] In the first driving mode, in one frame of the display panel 01, both the first shift register 211 and the second shift register 221 output valid scan signals.

[0068] In the second driving mode, in one frame of the display panel 01, one of the first shift register 211 and the second shift register 221 outputs a valid scan signal, while the other does not output a valid scan signal.

[0069] In this technical solution, in the first driving mode, in one frame of the display panel 01, the first shift register 211 and the second shift register 221 work together to scan the first sub-pixel row 111 and the second sub-pixel row 112 line by line. Simultaneously, since one of the first multiplexing unit 31 and the second multiplexing unit 32 is off and the other is on, the first sub-pixel column 121 or the second sub-pixel column 122 cannot refresh the display data, thereby reducing the power consumption of the display panel 01.

[0070] In the second driving mode, in a frame of the display panel 01, only the first shift register 211 or the second shift register 221 works, that is, only the first sub-pixel row 111 or the second sub-pixel row 112 refreshes the display data, instead of both the first sub-pixel row 111 and the second sub-pixel row 112 refreshing the display data, thereby reducing the power consumption of the display panel 01.

[0071] Figure 7 This is a schematic diagram of yet another display panel provided in an embodiment of this application. Figure 8 for Figure 7 The diagram shown is a timing diagram of a drive panel in the first drive mode. Figure 9 for Figure 7 The diagram shown is a timing diagram of a drive panel in the second drive mode.

[0072] In another technical solution of this application embodiment, please continue to refer to Figure 2 The first scanning unit 21 further includes a second scanning output terminal Po2, and the second scanning unit 22 further includes a first scanning output terminal Po1, that is, both the first scanning unit 21 and the second scanning unit 22 include a first scanning output terminal Po1 and a second scanning output terminal Po2.

[0073] In the first driving mode, in one frame of the display panel 01, the first scan output terminal Po1 and the second scan output terminal Po2 of the first scan unit 21 and the first scan output terminal Po1 and the second scan output terminal Po2 of the second scan unit 22 all output valid scan signals.

[0074] In this technical solution, under the first driving mode, both the first sub-pixel row 111 and the second sub-pixel row 112 are driven on both sides.

[0075] Furthermore, such as Figure 7 As shown, the first scanning unit 21 includes a first shift register 211 and a first switch K1. The first shift register 211 includes a first output terminal OUT1 and a second output terminal OUT2. The first output terminal OUT1 is electrically connected to the first scan output terminal Po1 of the first scanning unit 21, and the second output terminal OUT2 is electrically connected to the input terminal of the first switch K1. The output terminal of the first switch K1 is electrically connected to the second scan output terminal Po2 of the first scanning unit 21. That is, the first output terminal OUT1 of the first shift register 211 is electrically connected to the first sub-pixel row 111, and the second output terminal OUT2 of the first shift register 211 is electrically connected to the second sub-pixel row 112 through the first switch K1.

[0076] The second scanning unit 22 includes a second shift register 221 and a second switch K2. The second shift register 221 includes a third output terminal OUT3 and a fourth output terminal OUT4. The third output terminal OUT3 is electrically connected to the input terminal of the second switch K2, the output terminal of the second switch K2 is electrically connected to the first scan output terminal Po1 of the second scanning unit 22, and the fourth output terminal OUT4 is electrically connected to the second scan output terminal Po2 of the second scanning unit 22. That is, the third output terminal OUT3 of the second shift register 221 is electrically connected to the first sub-pixel 111 through the second switch K2, and the fourth output terminal OUT4 of the second shift register 221 is electrically connected to the second sub-pixel row 112.

[0077] like Figure 8 As shown, in the first driving mode, in one frame of the display panel 01, both the first switch K1 and the second switch K2 are turned on.

[0078] like Figure 9 As shown, in the second driving mode, in one frame of the display panel 01, both the first switch K1 and the second switch K2 are turned off.

[0079] In this technical solution, in the first driving mode, when both the first switch K1 and the second switch K2 are turned on in one frame of the display panel 01, the first output terminal OUT1 and the second output terminal OUT2 of the first shift register 211 can transmit scan signals to the first sub-pixel row 111 and the second sub-pixel row 112, respectively. Simultaneously, the third output terminal OUT3 and the fourth output terminal OUT4 of the second shift register 221 can also transmit scan signals to the first sub-pixel row 111 and the second sub-pixel row 112, respectively, thereby achieving dual-sided driving of the first sub-pixel row 111 and the second sub-pixel row 112. Of course, since one of the first multiplexing unit 31 and the second multiplexing unit 32 is turned off and the other is turned on, the first sub-pixel column 121 or the second sub-pixel column 122 cannot refresh the display data, thus reducing the power consumption of the display panel 01.

[0080] In the second driving mode, when both the first switch K1 and the second switch K2 are closed in one frame of the display panel 01, the first output terminal OUT1 of the first shift register 211 can transmit a scan signal to the first sub-pixel row 111, the second output terminal OUT2 cannot transmit a scan signal to the second sub-pixel row 112, the third output terminal OUT3 of the second shift register 221 cannot transmit a scan signal to the first sub-pixel row 111, and the fourth output terminal OUT4 can transmit a scan signal to the second sub-pixel row 112. Simultaneously, since only the first scanning unit 21 or the second scanning unit 22 operates in one frame of the display panel 01, that is, only the first output terminal OUT1 of the first shift register 211 transmits a scan signal to the first sub-pixel row 111, or only the fourth output terminal OUT4 of the second shift register 221 transmits a scan signal to the second sub-pixel row 112, thereby reducing the power consumption of the display panel 01.

[0081] Figure 10 This application provides another display panel driving timing diagram in a first driving mode. Figure 11 This is a driving timing diagram of another display panel provided in the second driving mode according to an embodiment of the present application.

[0082] In one embodiment of this application, in the first driving mode, the first multiplexing unit 31 and the second multiplexing unit 32 are alternately turned on in two adjacent frames of the display panel 01.

[0083] For example, combining Figure 2 , Figure 3 and Figure 10As shown, two adjacent frames of the display panel 01 include the nth frame (frame(n)) and the (n+1)th frame (frame(n+1)). In the nth frame (frame(n), both the first scan output terminal Po1 and the second scan output terminal Po2 output valid scan signals. Simultaneously, the first multiplexer unit 31 is turned on, and the second multiplexer unit 32 is turned off. That is, in the nth frame (frame(n), the first control signal line SR1, the second control signal line SR2, and the third control signal line SR3 transmit valid signals (such as high level) to control the first selection switch KH1, the second selection switch KH2, and the third selection switch KH3 of the first multiplexer unit 31 to turn on; the fourth control signal line SR4, the fifth control signal line SR5, and the sixth control signal line SR6 transmit valid signals (such as low level) to control the fourth selection switch KH4, the fifth selection switch KH5, and the sixth selection switch KH6 of the second selection unit 32 to turn off.

[0084] In the (n+1)th frame, both the first scan output terminal Po1 and the second scan output terminal Po2 output valid scan signals. Simultaneously, the first multiplexer unit 31 is turned off, and the second multiplexer unit 32 is turned on. That is, in the (n+1)th frame, the first control signal line SR1, the second control signal line SR2, and the third control signal line SR3 all transmit valid signals (e.g., low level) to control the first selection switch KH1, the second selection switch KH2, and the third selection switch KH3 of the first multiplexer unit 31 to turn off; the fourth control signal line SR4, the fifth control signal line SR5, and the sixth control signal line SR6 respectively transmit valid signals (e.g., high level) to control the fourth selection switch KH4, the fifth selection switch KH5, and the sixth selection switch KH6 of the second selection unit 32 to turn on.

[0085] In this embodiment, in two adjacent frames of the display panel 01, only the first sub-pixel column 121 refreshes display data in one frame, and only the second sub-pixel column 122 refreshes display data in the other frame. Due to the persistence of vision effect of the human eye, the human eye will still perceive the display image as having superior quality. This embodiment of the application, while reducing the power consumption of the display panel 01, helps to minimize the impact on the display quality of the display panel 01.

[0086] In one embodiment of this application, in the first driving mode, in two adjacent frames of the display panel 01, the first scan output terminal Po1 and the second scan output terminal Po2 alternately output valid scan signals.

[0087] Furthermore, in the second driving mode, in two adjacent frames of the display panel 01, the first scan output terminal Po1 of the first scan unit 21 and the second scan output terminal Po2 of the second scan unit 22 alternately output valid scan signals.

[0088] For example, combining Figure 2 , Figure 3 and Figure 11 As shown, two adjacent frames of the display panel 01 include the nth frame (n) and the (n+1)th frame (n+1). In the nth frame (n), both the first multiplexing unit 31 and the second multiplexing unit 32 are turned on. At the same time, only the first scan output terminal Po1 of the first scanning unit 21 outputs a valid scan signal, while the second scan output terminal Po2 of the first scanning unit 21, the first scan output terminal Po1 of the second scanning unit 22, and the second scan output terminal Po2 of the second scanning unit 22 do not output valid scan signals.

[0089] In the (n+1)th frame, both the first multiplexing unit 31 and the second multiplexing unit 32 are turned on. At the same time, only the second scan output terminal Po2 of the second scanning unit 22 outputs a valid scan signal, while the first scan output terminal Po1 of the first scanning unit 21, the second scan output terminal Po2 of the first scanning unit 21, and the first scan output terminal Po1 of the second scanning unit 22 do not output valid scan signals.

[0090] In this embodiment, in two adjacent frames of the display panel 01, only the first sub-pixel row 111 refreshes display data in one frame, and only the second sub-pixel row 112 refreshes display data in the other frame. Due to the persistence of vision effect of the human eye, the human eye will still perceive the display image as having superior quality. This embodiment of the application, while reducing the power consumption of the display panel 01, helps to minimize the impact on the display quality of the display panel 01.

[0091] Through experimental verification, the inventors of this application have demonstrated that, based on the display of text, existing display panels use a driving method that refreshes all sub-pixel display data in one frame, requiring a power consumption of approximately 559mW. In contrast, the display panel 01 provided in this application, in its first driving mode, displays a visual effect that is not significantly different from that of existing technologies, and its power consumption is approximately 510mW, which is about 49mW lower than that of existing technologies.

[0092] Based on the graphic image, existing display panels use a driving method that refreshes all sub-pixel display data in one frame, requiring a power consumption of approximately 567mW. However, the display panel 01 provided in this embodiment, in its second driving mode, displays an image with no significant visual difference from existing displays, and its power consumption is approximately 519mW, which is about 48mW lower than existing technologies.

[0093] The display panel 01 provided in this application embodiment can flexibly select the first driving mode or the second driving mode according to the display screen, ensuring that the display panel 01 has a relatively high quality screen while ensuring that the display panel 01 has low power consumption.

[0094] In one embodiment of this application, the display frequency of the display panel 01 in the first driving mode is f1, and the display frequency of the display panel 01 in the second driving mode is f2; wherein, f1≤f2.

[0095] In this embodiment, the display frequency of the display panel 01 in the first driving mode can be the same as its display frequency in the second driving mode, i.e., f1 = f2. For displaying complex images with high detail, the display panel 01 can adopt a reduced-frequency display method with two frames per display cycle in both the first and second driving modes. Odd-numbered rows or columns of sub-pixels are displayed in odd-numbered frames, and even-numbered rows or columns of sub-pixels are displayed in even-numbered frames, thereby reducing the power consumption of the display panel 01 while maintaining display quality.

[0096] Furthermore, compared to a simpler display image, the display panel 01 can be configured to have a higher display frequency in the second driving mode. This is because in the second driving mode, the total number of scan output terminals Po that output valid scan signals in one frame of the display image is smaller. This makes it possible to reduce the time interval between two adjacent first scan output terminals Po1 or two adjacent second scan output terminals Po2 output valid scan signals, thereby increasing the display frequency by compressing the display time of sub-pixels. Setting the display panel 01 to have a higher display frequency in the second driving mode helps to reduce the flickering of the display image.

[0097] Please continue to refer to this. Figure 7 In one embodiment of this application, the first switch K1 includes a first transistor T1, the first terminal of the first transistor T1 is electrically connected to the second output terminal OUT2 of the first shift register 211, the second terminal is electrically connected to the second scan output terminal Po2 of the first scan unit 21, and the gate is electrically connected to the first signal line SW.

[0098] The second switch K2 includes a second transistor T2. The first terminal of the second transistor T2 is electrically connected to the third output terminal OUT3 of the second shift register 221, the second terminal is electrically connected to the first scan output terminal Po1 of the second scan unit 22, and the gate is electrically connected to the first signal line SW.

[0099] The first transistor T1 and the second transistor T2 have the same channel type.

[0100] In this embodiment of the application, in the first driving mode of the display panel 01, the first signal line SW can transmit an effective signal and simultaneously control the first transistor T1 and the second transistor T2 to turn on, thereby ensuring that the first switch K1 and the second switch K2 are turned on, and thus ensuring that in a frame of the display panel 01, the first sub-pixel row 111 and the second sub-pixel row 112 can be scanned line by line.

[0101] In the second driving mode of the display panel 01, the first signal line SW can transmit a valid signal and simultaneously control the first transistor T1 and the second transistor T2 to turn off, thereby ensuring that the first switch K1 and the second switch K2 are turned off, and thus ensuring that in a frame of the display panel 01, only the first sub-pixel row 111 receives a valid scan signal, or only the second sub-pixel row 112 receives a valid scan signal.

[0102] In this embodiment of the application, the gates of the first transistor T1 and the second transistor T2 are both electrically connected to the first signal line SW, which can reduce the number of first signal lines SW in the display panel 01, thereby reducing the design difficulty and manufacturing cost of the display panel 01.

[0103] In one embodiment of this application, please continue to refer to Figure 1 and Figure 2 The display panel 01 includes a first data signal terminal 41 and a second data signal terminal 42. The first data signal terminal 41 transmits data signals to the first sub-pixel column 121 through the first multiplexing unit 31, and the second data signal terminal 42 transmits data signals to the second sub-pixel column 122 through the second multiplexing unit 32.

[0104] The switching state of the first data signal terminal 41 is the same as that of the first multiplexer unit 31. Furthermore, the switching state of the second data signal terminal 42 is the same as that of the second multiplexer unit 32.

[0105] In other words, when the first multiplexing unit 31 is turned on, the first data signal terminal 41 transmits data signals simultaneously; when the first multiplexing unit 31 is turned off, the first data signal terminal 41 stops transmitting data signals simultaneously.

[0106] When the second multiplexing unit 32 is turned on, the second data signal terminal 41 transmits data signals simultaneously; when the second multiplexing unit 32 is turned off, the second data signal terminal 41 stops transmitting data signals simultaneously.

[0107] In this embodiment of the application, in the first driving mode, in a frame of the display panel 01, only the first multiplexing unit 31 or only the second multiplexing unit 32 is turned on. In a frame of the display panel 01, only the first data signal terminal 41 transmits data signals or only the second data signal terminal 42 transmits data signals, which is beneficial to further reduce the power consumption of the display panel 01.

[0108] Please continue to refer to this. Figure 1 and Figure 2 In one embodiment of this application, the sub-pixels 10 electrically connected to the same multiplexing unit 20 include a first color sub-pixel 101, a second color sub-pixel 102, and a third color sub-pixel 103. That is, the first multiplexing unit 21 is electrically connected to the first color sub-pixel 101, the second color sub-pixel 102, and the third color sub-pixel 103, and the second multiplexing unit 22 is electrically connected to the first color sub-pixel 101, the second color sub-pixel 102, and the third color sub-pixel 103.

[0109] Optionally, the first color sub-pixel 101 is a red sub-pixel, the second color sub-pixel 102 is a blue sub-pixel, and the third color sub-pixel 103 is a green sub-pixel.

[0110] In this embodiment of the application, in the first driving mode, even if only the first multiplexing unit 31 or the second multiplexing unit 32 is turned on in a frame of the display panel 01, the full-color display of the display screen can still be guaranteed.

[0111] Figure 12 This is a flowchart of a display panel driving method provided in an embodiment of this application.

[0112] This application also provides a driving method for a display panel 01, used to drive the display panel 01 as described in the above embodiments. The structure of the display panel 01 can be as follows: Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown. Display panel 01 includes a first driving mode and a second driving mode, as follows. Figure 12 As shown, the driving method includes:

[0113] Step B1: In the first driving mode, in a frame of the display panel 01, both the first scan output terminal Po1 and the second scan output terminal Po2 output valid scan signals, and in the first multiplexing unit 21 and the second multiplexing unit 22, one is turned on and the other is turned off.

[0114] Step B2: In the second driving mode, in a frame of the display panel 01, both the first multiplexing unit 21 and the second multiplexing unit 22 are turned on, and in the first scan output terminal Po1 and the second scan output terminal Po2, one outputs a valid scan signal and the other does not output a valid scan signal.

[0115] It should be noted that there is no sequential relationship between steps B1 and B2. The display panel 01 can flexibly select to execute either step B1 or step B2 according to the screen.

[0116] In the driving method provided in this application embodiment, in the first driving mode, in one frame of the display panel 01, the first scan output terminal Po1 and the second scan output terminal Po2 can scan the first sub-pixel row 111 and the second sub-pixel row 112 line by line. However, only the first multiplexing unit 31 can transmit data signals to the first sub-pixel column 121, or only the second multiplexing unit 32 can transmit data signals to the second sub-pixel column 122. That is, in one frame, there may be instances where the first sub-pixel column 121 or the second sub-pixel column 122 does not need to refresh the display data, thereby helping to reduce the power consumption of the display panel.

[0117] In the second driving mode, within a frame of the display panel 01, the first multiplexing unit 31 and the second multiplexing unit 32 can transmit data signals to different sub-pixel columns 12 respectively. However, only the first sub-pixel row 111 or only the second sub-pixel row 112 receives a valid scan signal. That is, within a frame, there may be instances where the first sub-pixel row 111 or the second sub-pixel row 112 does not need to refresh the display data, thereby helping to reduce the power consumption of the display panel 01.

[0118] In one embodiment of this application, the driving method further includes:

[0119] Step B3: In the first driving mode, in two adjacent frames of the display panel 01, the first multiplexing unit 21 and the second multiplexing unit 22 are alternately turned on.

[0120] Step B4: In the second driving mode, in two adjacent frames of the display panel 01, the first scan output terminal Po1 and the second scan output terminal Po2 alternately output valid scan signals.

[0121] In this embodiment, in two adjacent frames of the display panel 01, only the first sub-pixel row 111 or the first sub-pixel column 121 refreshes display data in one frame, and only the second sub-pixel row 112 or the second sub-pixel column 122 refreshes display data in the other frame. Due to the persistence of vision effect of the human eye, the human eye will still perceive the display image as having superior quality. This embodiment of the application, while reducing the power consumption of the display panel 01, helps to minimize the impact on the display quality of the display panel 01.

[0122] Figure 13 This is a schematic diagram of a display device provided in an embodiment of this application.

[0123] This application provides a display device 02, such as... Figure 13 As shown, the display device 02 includes the display panel 01 as provided in the above embodiments. The display device 02 provided in this application embodiment can be an electronic device such as a computer, television, mobile phone, or vehicle display.

[0124] In the display device 02, in a frame of the display panel 01, if one of the first scan output terminal Po1 and the second scan output terminal Po2 is set not to output a valid scan signal, and / or one of the first multiplexing unit 31 and the second multiplexing unit 32 is turned off, then some sub-pixel rows 11 and / or some sub-pixel columns 12 do not need to refresh the display data, which helps to reduce the power consumption of the display panel 01.

[0125] Furthermore, in a single frame of the display panel 01, since the display of some sub-pixel rows 11 or sub-pixel columns 12 can remain unchanged, it is also beneficial to reduce the flickering of the display and improve the quality of the display.

[0126] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
