[0050] In one embodiment, a display device is provided, including a display panel as described in any of the above embodiments.

[0051] The aforementioned display panel and display device have at least one pixel group arranged in the display area array. Each pixel group includes pixel units of at least one color, and each pixel unit includes N sub-pixels of the same color, where N≥2. Each sub-pixel is connected to a corresponding switching element, and each sub-pixel within the same pixel unit is connected in parallel to the same pixel driving circuit via its corresponding switching element. Compared to the traditional design where one sub-pixel is driven by one pixel driving circuit, this design significantly reduces the number of pixel driving circuits, which helps to reduce the area occupied by the pixel driving circuits in the display area, freeing up more space for the light-emitting area. This can potentially increase the aperture ratio and overall brightness of the panel, thereby achieving a higher pixel density (PPI) and improving the resolution of the display panel. In addition, the display panel includes N light-emitting control signal lines, the same number as the pixel units. Each light-emitting control signal line is connected to the control terminal of the switching element of a sub-pixel within the same pixel unit. The sub-pixels connected to by each light-emitting control signal line within the same pixel unit are different. Within a display frame, the light-emitting control signals EM transmitted by the N light-emitting control signal lines time-divisionally transition to an active level to control the corresponding connected switching elements to conduct in a time-division manner, enabling the sub-pixels within the same pixel unit to emit light in a time-division manner. It can be understood that the above time-division driving method is implemented by combining pixel arrangement and drive trace design, without requiring modification to the sub-pixel structure, and does not affect the sub-pixel light-emitting performance, effectively improving the yield and display effect of the display panel. Furthermore, since the sub-pixels corresponding to the same pixel driving circuit will not light up simultaneously, the instantaneous maximum current required by a single pixel driving circuit is greatly reduced, alleviating the power supply load and performance pressure on the driving transistors, which helps improve display uniformity and extend device lifespan.

Meanwhile, the term "and / or" as used in this specification includes any and all combinations of the associated listed items.

[0071] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0072] With the development of display technology, OLED has become the mainstream display panel due to its many advantages, such as wide viewing angle, fast response speed, no need for backlighting, and the ability to achieve flexible display. It is widely used in various consumer electronics products such as mobile phones, televisions, laptops, and desktop computers.

[0073] However, the inventors discovered that one type of OLED display panel using a time-division driving method employs a design with isolation pillars (larger at the top and smaller at the bottom) to divide the cathode. By controlling the cathode potential of different rows, different rows are illuminated in a time-division manner, thus combining two or three time-division white images into a single white image. Correspondingly, sub-pixels of different colors within different rows can be driven alternately by the same pixel driving circuit, achieving color display through color mixing at different times. This design significantly reduces the number of pixel driving circuits, increases the design space for pixel driving circuits, and thereby improves the display resolution or transparency.

[0074] However, using an isolation pillar structure to isolate the cathode may reduce the yield of the display panel. For example, an abnormality in a single isolation pillar structure can cause a short circuit between two rows of cathodes, resulting in abnormal potential and appearing as two dark lines. Simultaneously, the increased resistance of the cathode lines after being isolated by the isolation pillar structure will lead to increased voltage differences on the cathode lines, thereby causing uneven brightness or crosstalk problems in the display panel. Therefore, it is necessary to propose targeted solutions to address the problem of reduced display panel yield and poor display performance under the aforementioned time-sharing driving method.

[0075] Based on this, this application provides a display panel. Figure 1 The diagram shown is a schematic representation of the pixel arrangement of a display panel according to an embodiment of this application. Figure 2 The diagram shown is a circuit connection diagram of a display panel provided in an embodiment of this application.

[0076] In one exemplary embodiment, reference is made to Figure 1 and Figure 2 The display panel includes a display area AA; at least one pixel group 100 arranged in an array in the display area AA, the pixel group 100 including pixel units 110 of at least one color, each pixel unit 110 including N sub-pixels 111 of the same color, N≥2; a plurality of switching elements 200, each switching element 200 being connected to each sub-pixel 111 in a one-to-one correspondence; and at least one pixel driving circuit 300, wherein each sub-pixel 111 in the same pixel unit 110 is connected in parallel to the same pixel driving circuit 300 via the correspondingly connected switching elements 200. 0; N light-emitting control signal lines 400, each light-emitting control signal line 400 is connected to the control terminal of the switching element 200 of a sub-pixel 111 within the same pixel unit 110, and the sub-pixels 111 within the same pixel unit 110 connected to each light-emitting control signal line 400 are different; within a display frame, the light-emitting control signal EM transmitted by the N light-emitting control signal lines 400 time-divisionally jumps to an effective level to control the corresponding connected switching element 200 to be turned on time-divisionally, so that the sub-pixels 111 within the same pixel unit 110 emit light in a time-division manner.

[0077] The display panel described in this application can be an organic light-emitting diode (OLED) display panel or a micro-light-emitting diode (Micro-LED) display panel. The display panel may include a display area AA and a non-display area (not shown in the figure), where the display area AA is the area on the display panel used for image display. Specifically, in the display area AA, multiple pixel groups 100 are arranged in an array, and each pixel group 100 may contain pixel units 110 capable of combining multiple colors required for full-color display. For example, a pixel group 100 may include red (R) pixel units, green (G) pixel units, and blue (B) pixel units. In other embodiments, the pixel group 100 may also include pixel units of more colors, such as white (W) pixel units and yellow (Y) pixel units, etc., which can be designed according to actual display requirements in practical applications.

[0078] Furthermore, the pixel unit 110 of each color provided in this application does not contain a single sub-pixel, but is composed of N (N≥2) sub-pixels 111 of the same color. For example, taking N=2 as an example, each pixel unit 110 contains two sub-pixels 111 with the same emission color, and these two sub-pixels 111 can have the same structure and size.

[0079] It is understood that the arrangement of each pixel unit 110 within pixel group 100 is not limited, nor is the arrangement of each sub-pixel 111 within pixel unit 110; it can be set according to actual pixel arrangement requirements. For example, in one example, refer to... Figure 1 Each pixel unit 110 within pixel group 100 can be arranged in an array, and each sub-pixel 111 within pixel unit 110 can also be arranged in an array to form a traditional array-style sub-pixel arrangement. In other embodiments, each pixel unit 110 within pixel group 100 can also be arranged in a cross pattern, so that sub-pixels 111 of different colors are arranged adjacently to form a sub-pixel group. For example, a sub-pixel group is composed of a combination of one sub-pixel within each color pixel unit 110. The arrangement of each sub-pixel in the sub-pixel group is not limited and can be a triangular pixel arrangement, a hexagonal pixel arrangement, or other types of arrangement.

[0080] Furthermore, all sub-pixels 111 within the same pixel unit 110, i.e., sub-pixels 111 of the same color within each pixel unit 110, share the same pixel driving circuit 300 and emit light in response to the driving current of the pixel driving circuit 300. The pixel driving circuit 300 is typically a standard compensation circuit containing a driving transistor and a storage capacitor, used to generate a stable driving current unaffected by a threshold voltage to drive the corresponding sub-pixel to emit light. It is understood that this application does not limit the specific circuit structure of the pixel driving circuit 300, and can select commonly used pixel driving circuit structures in the art, such as 2T1C pixel circuits and their variations, 7T1C pixel circuits and their variations, etc. Compared with the traditional design method where one sub-pixel is driven by one pixel driving circuit, this embodiment can significantly reduce the number of pixel driving circuits, which is beneficial to reducing the area occupied by the pixel driving circuits in the display area, thereby achieving a higher pixel density (Pixel Per Inch, PPI) and improving the resolution of the display panel.

[0081] Each sub-pixel 111 is connected to a switching element 200, and all sub-pixels 111 belonging to the same pixel unit 110 are connected in parallel to the same pixel driving circuit 300 through their respective corresponding switching elements 200, so as to share the driving current of the same pixel driving circuit 300. It can be understood that the pixel driving circuit 300 is capable of driving any sub-pixel 111 in the pixel unit 110, but at the same time, a light emission control signal line 400 can be designed to select the switching element 200 corresponding to one sub-pixel 111 in the same pixel unit 110 to drive one sub-pixel 111 to emit light, that is, to realize time-division driving light emission.

[0082] For example, the switching element 200 can be implemented using different switching transistors or switching devices. In this embodiment, the switching element 200 can be implemented using a thin film transistor (TFT). The first electrode (e.g., the source electrode) of the TFT is connected to the common node of the pixel driving circuit 300, the second electrode (e.g., the drain electrode) is connected to the anode of the sub-pixel 111, and the control electrode (gate electrode) is used to receive the light emission control signal EM transmitted on the light emission control signal line 400. The switching element 200 functions similarly to a gating switch, controlling whether its corresponding sub-pixel 111 is connected to the pixel driving circuit. The common node of the pixel driving circuit 300 can refer to the drain of the driving transistor in the pixel driving circuit.

[0083] To achieve time-division multiplexing of light emission, this embodiment of the application provides N light emission control signal lines 400, that is, the number of light emission control signal lines is consistent with the number of sub-pixels contained in the pixel unit 110. The N light emission control signal lines 400 output light emission control signals EM to the control terminals of the switching elements 200 of each sub-pixel to control the on and off of the switching elements 200.

[0084] Specifically, firstly, a light-emitting control signal line 400 is connected to the control terminal of the switching element 200 of a sub-pixel 111 within the pixel unit 110. This means that for the same light-emitting control signal line 400, it is only connected to the switching element 200 of one sub-pixel 111 within each pixel unit 110. Which sub-pixel 111's switching element 200 is specifically connected to by the same light-emitting control signal line 400 within each pixel unit 110 is not limited and is determined based on the specific wiring design in the application. For example, taking a sub-pixel array arrangement as an example, the same light-emitting control signal line 400 can be connected to the switching elements 200 of the sub-pixels 111 in the same row / column within each pixel unit 110 to achieve time-division lighting of the sub-pixels 111 by row / column. Alternatively, the same light-emitting control signal line 400 can be connected to the switching elements 200 of the sub-pixels 111 in different rows / columns within each pixel unit 110 to avoid scrolling of the displayed image when the sub-pixels 111 emit light by row / column.

[0085] Secondly, the sub-pixels 111 connected to each of the light-emitting control signal lines 400 within the same pixel unit 110 are different. That is, for the same pixel unit 110, if the first light-emitting control signal line is connected to the switching element 200 of the first sub-pixel 111 within that pixel unit 110, then the second light-emitting control signal line can be connected to the switching elements 200 of all sub-pixels 111 except the first sub-pixel 111, so as to ensure that all sub-pixels 111 within a pixel unit 110 can be driven to emit light.

[0086] Through the aforementioned signal line connection design, combined with the time-division multiplexing of the light-emitting control signals EM transmitted by the N light-emitting control signal lines 400 within the same display frame, the corresponding connected switching elements 200 are time-division multiplexing to conduct, causing the sub-pixels 111 within the same pixel unit 110 to emit light in a time-division multiplexing manner. Thus, although only one sub-pixel 111 may be emitting light within each pixel unit 110 at any given moment, due to the persistence of vision, the observer perceives a continuous brightness resulting from the fusion of multiple sub-pixels. The total luminous intensity is the integral effect of the luminous intensity of all sub-pixels within the display frame, and can be precisely controlled by adjusting the luminous duration of each sub-pixel within the pixel unit 110.

[0087] The aforementioned display panel has at least one pixel group arranged in the display area array. Each pixel group includes pixel units of at least one color, and each pixel unit includes N sub-pixels of the same color, where N≥2. Each sub-pixel is connected to a corresponding switching element, and each sub-pixel within the same pixel unit is connected in parallel to the same pixel driving circuit via its corresponding switching element. Compared to the traditional design where one sub-pixel is driven by one pixel driving circuit, this design significantly reduces the number of pixel driving circuits, which helps to reduce the area occupied by the pixel driving circuits in the display area, freeing up more space for the light-emitting area. This can potentially increase the panel's aperture ratio and overall brightness, thereby achieving a higher pixel density (PPI) and improving the display panel's resolution. In addition, the display panel includes N light-emitting control signal lines, the same number as the pixel units. Each light-emitting control signal line is connected to the control terminal of the switching element of a sub-pixel within the same pixel unit. The sub-pixels connected to by each light-emitting control signal line within the same pixel unit are different. Within a display frame, the light-emitting control signals EM transmitted by the N light-emitting control signal lines time-divisionally transition to an active level to control the corresponding connected switching elements to conduct in a time-division manner, enabling the sub-pixels within the same pixel unit to emit light in a time-division manner. It can be understood that the above time-division driving method is implemented by combining pixel arrangement and drive trace design, without requiring modification to the sub-pixel structure, and does not affect the sub-pixel light-emitting performance, effectively improving the yield and display effect of the display panel. Furthermore, since the sub-pixels corresponding to the same pixel driving circuit will not light up simultaneously, the instantaneous maximum current required by a single pixel driving circuit is greatly reduced, alleviating the power supply load and performance pressure on the driving transistors, which helps improve display uniformity and extend device lifespan.

[0088] In an exemplary embodiment, the display frame includes N display subframes, and the light emission control signals transmitted by the N light emission control signal lines sequentially change to an active level within the N display subframes.

[0089] Specifically, to achieve time-division multiplexing of sub-pixels, a complete display frame may include N display sub-frames. The number of display sub-frames is consistent with the number of sub-pixels contained in pixel unit 110. The light emission control signals EM transmitted by the N light emission control signal lines sequentially transition to an active level within the N display sub-frames. Furthermore, the N light emission control signal lines 400 serve as the control terminals for the switching elements 200 of each sub-pixel, sequentially outputting the light emission control signals EM within the N display sub-frames to control the switching elements 200 to conduct sequentially, thereby causing the sub-pixels within the same pixel unit to emit light sequentially.

[0090] For example, the end time of the effective level of the previous display subframe coincides with the start time of the effective level of the current display subframe. This can be understood as the display subframes contained within a complete display frame being continuous, and when the sub-pixel corresponding to the current display subframe starts to emit light, the sub-pixel corresponding to the previous display subframe stops emitting light.

[0091] For example, the start time of the effective level of the current display subframe is before the end time of the effective level of the previous display subframe. This can be understood as the display subframes within a complete display frame partially overlapping. When the subpixel corresponding to the current display subframe starts emitting light, the subpixel corresponding to the previous display subframe has not yet stopped emitting light, in order to avoid the display screen being perceived as slightly flickering or jittering due to response delay during the switching intervals between display subframes, thus improving the uniformity of overall brightness.

[0092] For example, the effective pulse widths of the light emission control signals transmitted by the N light emission control signal lines are the same. This can be understood as the fact that, theoretically, the duration of a single light emission is equal for each sub-pixel within the same pixel unit connected to each light emission control signal line in each display frame, further improving the uniformity of the overall light emission brightness.

[0093] Figure 3 The diagram shown is a schematic representation of the pixel arrangement of a display panel according to an embodiment of this application. The following embodiments are explained using the example of each pixel unit and each pixel being arranged in an array.

[0094] In one exemplary embodiment, reference is made to Figure 1 and Figure 3 Each pixel unit 110 in pixel group 100 is arranged in a first direction, and each sub-pixel 111 in pixel unit 110 is arranged in a second direction, wherein the first direction and the second direction intersect.

[0095] Specifically, the first direction and the second direction intersect. In this embodiment, the first direction and the second direction can be set to be two mutually perpendicular directions. Such an arrangement is beneficial for wiring optimization and display uniformity.

[0096] In one example, refer to Figure 1 The first direction can be the row direction X, and the second direction can be the column direction Y. The pixel units 110 in pixel group 100 are arranged in the row direction X, and the sub-pixels 111 in pixel unit 110 are arranged in the column direction Y. In one example, refer to... Figure 3 The first direction can be the column direction Y, and the second direction can be the row direction X. Each pixel unit 110 in pixel group 100 is arranged in the column direction Y, and each sub-pixel 111 in pixel unit 110 is arranged in the row direction X.

[0097] In one example, each pixel group includes red pixel units, green pixel units, and blue pixel units arranged sequentially in a first direction. See [link to example]. Figure 1 and Figure 3 A red pixel unit includes N red sub-pixels R, a green pixel unit includes N green sub-pixels G, and a blue pixel unit includes N blue sub-pixels B. Therefore, after each pixel group 100 includes red pixel units, green pixel units, and blue pixel units arranged sequentially in the first direction, it is possible to form sub-pixels of different colors arranged in the first direction within the same pixel group, for example... Figure 1 Within the same pixel group of 100, the sub-pixels arranged in the same row are red sub-pixel R, green sub-pixel G, and blue sub-pixel B.

[0098] Figure 4 The diagram shown is a schematic representation of the sub-pixels of a display panel within each time interval according to an embodiment of this application. Figure 5 The diagram shown is a circuit connection diagram of a display panel provided in an embodiment of this application. Figure 6 The diagram shown is a driving timing diagram of a display panel according to an embodiment of this application. The following embodiment is explained using the example of each pixel unit being arranged in an array and N=2.

[0099] In one exemplary embodiment, reference is made to Figure 4 Each pixel unit 110 includes two sub-pixels 111 of the same color. The pixel units 110 in pixel group 100 are arranged in rows, and the sub-pixels 111 in pixel unit 110 are arranged in columns. Sub-pixels 111 in the same row within the same pixel group 100 constitute sub-pixel group 120. Figure 4 For example, each pixel group includes red pixel units, green pixel units and blue pixel units arranged in a row direction. The red pixel unit includes red sub-pixels R1 and R2, the green pixel unit includes green sub-pixels G1 and G2, and the blue pixel unit includes blue sub-pixels B1 and B2.

[0100] Reference Figure 5 The display panel's light emission control signal lines include a first light emission control signal line 401 and a second light emission control signal line 402. The first light emission control signal line 401 is used to transmit a first light emission control signal EM1, and the second light emission control signal line 402 is used to transmit a second light emission control signal EM2.

[0101] The first light emission control signal line 401 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the first target sub-pixel group. The first target sub-pixel group includes the 2M-1th sub-pixel group 120 in odd-numbered pixel group column A and the 2Mth sub-pixel 120 in even-numbered pixel group column B. The second light emission control signal line 402 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the second target sub-pixel group. The second target sub-pixel group includes the 2Mth sub-pixel group 120 in odd-numbered pixel group column A and the 2M-1th sub-pixel group 120 in even-numbered pixel group column B. Here, M is an integer greater than or equal to 1.

[0102] Specifically, after arranging each pixel unit 110 in the pixel group 100 in rows and each sub-pixel 111 in the pixel unit 110 in columns, the red sub-pixel R1, green sub-pixel G1 and blue sub-pixel B1 arranged in the same row in the same pixel group 100 will form a sub-pixel group 120.

[0103] And corresponding Figure 6 When N=2, the display panel needs to divide the display frame into two display sub-frames to achieve time-division driving, that is, including Figure 6 T1 and T2 are shown. Within the first display subframe T1, the first light emission control signal EM1 transmitted on the first light emission control signal line 401 transitions to an active level, used to control the light emission of the 2M-1th sub-pixel group 120 in odd-numbered pixel group A and the 2Mth sub-pixel group 120 in even-numbered pixel group B, as shown... Figure 4 (1) As shown. Within the second display subframe T2, the second light emission control signal EM2 transmitted by the second light emission control signal line 402 switches to an active level, used to control the light emission of the 2Mth sub-pixel group 120 in the odd-numbered pixel group column A and the 2M-1th sub-pixel group 120 in the even-numbered pixel group column B, as shown. Figure 4 As shown in (2).

[0104] This design allows each sub-pixel group 120 on odd-numbered pixel group A and even-numbered pixel group B to form a structure when the two light-emitting control signals EM1 and EM2 alternately transition to an active level within their corresponding display sub-frames. Figure 4 The chessboard-style time-sharing drive shown in the diagram allows the luminous sub-pixels to be spatially staggered, making it easier for the human eye to integrate them into a continuous image, resulting in a significant improvement in dynamic clarity.

Sub-pixels 111 in the same row within the same pixel group 100 constitute a sub-pixel group 120. Similar to the previous embodiment, each pixel group includes red pixel units, green pixel units, and blue pixel units arranged sequentially in a row direction. The red pixel unit includes red sub-pixels R1, R2, and R3; the green pixel unit includes green sub-pixels G1, G2, and G3; and the blue pixel unit includes blue sub-pixels B1, B2, and B3.

[0107] Reference Figure 8 The light emission control signal lines of the display panel include a first light emission control signal line 401, a second light emission control signal line 402, and a third light emission control signal line 403.

[0108] The first light emission control signal line 401 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the first target sub-pixel group. The first target sub-pixel group includes the 3M-2nd sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M-1st sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3Mth sub-pixel group 120 in the 3Y pixel group column F. The second light emission control signal line 402 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the second target sub-pixel group.

The third target sub-pixel group includes the 3Mth sub-pixel group 120 in the 3Y-2nd pixel group column D, the 3M-2nd sub-pixel group 120 in the 3Y-1st pixel group column E, and the 3M-1st sub-pixel group 120 in the 3Y pixel group column F. Here, M is an integer greater than or equal to 1, and Y is an integer greater than or equal to 1.

[0109] Specifically, after arranging each pixel unit 110 in the pixel group 100 in rows and each sub-pixel 111 in the pixel unit 110 in columns, the red sub-pixel R1, green sub-pixel G1 and blue sub-pixel B1 arranged in the same row in the same pixel group 100 constitute a sub-pixel group 120.

[0110] And corresponding Figure 9 When N=3, the display panel needs to divide the display frame into three display sub-frames to achieve time-division driving, that is, including Figure 9 T1, T2, and T3 are shown. Within the first display subframe T1, the first light emission control signal EM1 transmitted on the first light emission control signal line 401 transitions to an active level, used to control the light emission of the 3M-2nd sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M-1st sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3Mth sub-pixel group 120 in the 3Y pixel group column F, as shown. Figure 7 (1) As shown. Within the second display subframe T2, the second light emission control signal EM2 transmitted by the second light emission control signal line 402 switches to an active level, used to control the light emission of the 3M-1 sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3M-2 sub-pixel group 120 in the 3Y pixel group column F, as shown. Figure 7 (2) As shown. Within the third display subframe T3, the third light emission control signal EM3 transmitted by the third light emission control signal line 403 switches to an active level, used to control the light emission of the 3Mth sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M-2nd sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3M-1st sub-pixel group 120 in the 3Y pixel group column F, as shown. Figure 7 As shown in (3).

[0111] With this design, when the three light-emitting control signals EM1, EM2, and EM3 alternately transition to an active level within their corresponding display sub-frames, each sub-pixel group 120 on three adjacent pixel groups can form a structure like... Figure 7 The three-row chessboard-style time-sharing drive shown in the figure allows the luminous sub-pixels to be spatially staggered, making it easier for the human eye to integrate them into a continuous image, resulting in a significant improvement in dynamic clarity.

Figure 11 The diagram shown is a circuit connection schematic of a display panel according to an embodiment of this application. The following embodiment is explained using the example of each pixel unit and each pixel being arranged in an array, with N=2.

[0113] In one exemplary embodiment, reference is made to Figure 10 Each pixel unit 110 includes two sub-pixels 111 of the same color. The pixel units 110 in the pixel group 100 are arranged in rows, and the sub-pixels 111 in the pixel unit 110 are arranged in columns. Similarly to the above embodiment, each pixel group 100 includes red pixel units, green pixel units, and blue pixel units arranged sequentially in a row direction. Specifically, the red pixel unit includes red sub-pixels R1 and R2, the green pixel unit includes green sub-pixels G1 and G2, and the blue pixel unit includes blue sub-pixels B1 and B2.

[0114] refer to Figure 11 The light emission control signal lines of the display panel include a first light emission control signal line 401 and a second light emission control signal line 402. The first light emission control signal line 401 is used to transmit a first light emission control signal EM1, and the second light emission control signal line 402 is used to transmit a second light emission control signal EM2.

[0115] The first light emission control signal line 401 is connected to the control terminal of the switching element 200 corresponding to the first target sub-pixel. The first target sub-pixel includes the 2M-1th sub-pixel 111 in the odd-numbered sub-pixel column G and the 2Mth sub-pixel 111 in the even-numbered sub-pixel column H. The second light emission control signal line 402 is connected to the control terminal of the switching element 200 corresponding to the second target sub-pixel. The second target sub-pixel includes the 2Mth sub-pixel 111 in the odd-numbered sub-pixel column G and the 2M-1th sub-pixel 111 in the even-numbered sub-pixel column H; where M is an integer greater than or equal to 1.

[0116] Specifically, after arranging each pixel unit 110 in pixel group 100 in rows and each sub-pixel 111 in pixel unit 110 in columns, a structure is formed as shown below. Figure 10 The sub-pixel array arrangement is shown. Furthermore, in this embodiment, the light emission control signal line can be connected to different sub-pixels in each sub-pixel column to achieve time-division driving.

[0117] correspond Figure 6 When N=2, the display panel needs to divide the display frame into two display sub-frames to achieve time-division driving, that is, including Figure 6 T1 and T2 are shown. (Refer to...) Figure 10 and Figure 11 Within the first display subframe T1, the first light emission control signal EM1 transmitted on the first light emission control signal line 402 transitions to an active level, used to control the light emission of the 2M-1th sub-pixel 111 in the odd-numbered sub-pixel column G and the 2Mth sub-pixel 111 in the even-numbered sub-pixel column H, as shown below. Figure 10(1) As shown.

[0118] With this design, when the two light-emitting control signals EM1 and EM2 alternately transition to an active level within their corresponding display sub-frames, each sub-pixel 111 on the odd-numbered sub-pixel column G and the even-numbered sub-pixel column H can form a structure as shown in the image. Figure 10 The chessboard-style time-sharing drive shown in the diagram allows the luminous sub-pixels to be spatially staggered, making it easier for the human eye to integrate them into a continuous image, resulting in a significant improvement in dynamic clarity.

[0119] Figure 12 The diagram shown is a schematic representation of the sub-pixels of a display panel within each time interval according to an embodiment of this application. Figure 13 The diagram shown is a circuit connection schematic of a display panel according to an embodiment of this application. The following embodiment is explained using the example of each pixel unit and each pixel being arranged in an array, with N=3.

[0120] In one exemplary embodiment, reference is made to Figure 12 Each pixel unit 110 includes three sub-pixels 111 of the same color. The pixel units 110 in the pixel group 100 are arranged in rows, and the sub-pixels 111 in the pixel unit 110 are arranged in columns. Similarly to the above embodiment, each pixel group 100 includes red pixel units, green pixel units, and blue pixel units arranged sequentially in a row direction. Specifically, the red pixel unit includes red sub-pixels R1, R2, and R3; the green pixel unit includes green sub-pixels G1, G2, and G3; and the blue pixel unit includes blue sub-pixels B1, B2, and B3.

[0121] Reference Figure 13 The light emission control signal lines of the display panel include a first light emission control signal line 401, a second light emission control signal line 402, and a third light emission control signal line 403. The first light emission control signal line 401 is used to transmit a first light emission control signal EM1, the second light emission control signal line 402 is used to transmit a second light emission control signal EM2, and the second light emission control signal line 403 is used to transmit a second light emission control signal EM3.

[0122] Reference Figure 12 and Figure 13The first light emission control signal line 401 is connected to the control terminal of the switching element 200 corresponding to the first target sub-pixel. The first target sub-pixel includes the 3M-2nd sub-pixel 111 in the 3Y-2nd sub-pixel column I, the 3M-1st sub-pixel 111 in the 3Y-1st sub-pixel column J, and the 3Mth sub-pixel 111 in the 3Y sub-pixel column K. The second light emission control signal line 402 is connected to the control terminal of the switching element 200 corresponding to the second target sub-pixel. The second target sub-pixel includes the 3M-1st sub-pixel 111 in the 3Y-2nd sub-pixel column I, the 3Mth sub-pixel 111 in the 3Y-1st sub-pixel column J, and the 3M-2nd sub-pixel 111 in the 3Y sub-pixel column K. The third light-emitting control signal line 403 is connected to the control terminal of the switching element 200 corresponding to the third target sub-pixel. The third target sub-pixel includes the 3Mth sub-pixel 111 in the 3Y-2nd sub-pixel column I, the 3M-2nd sub-pixel 111 in the 3Y-1st sub-pixel column J, and the 3M-1st sub-pixel in the 3Y sub-pixel column K. Here, M is an integer greater than or equal to 1, and Y is an integer greater than or equal to 1.

[0123] Specifically, after arranging each pixel unit 110 in pixel group 100 in rows and each sub-pixel 111 in pixel unit 110 in columns, a structure is formed as shown below. Figure 12 The sub-pixel array arrangement is shown. Furthermore, in this embodiment, the light emission control signal line can be connected to different sub-pixels in each sub-pixel column to achieve time-division driving.

[0124] And corresponding Figure 9 When N=3, the display panel needs to divide the display frame into three display sub-frames to achieve time-division driving, that is, including Figure 9 T1, T2, and T3 are shown. Within the first display subframe T1, the first light emission control signal EM1 transmitted on the first light emission control signal line 401 transitions to an active level, used to control the light emission of the 3M-2nd sub-pixel 111 in the 3Y-2nd sub-pixel column I, the 3M-1st sub-pixel 111 in the 3Y-1st sub-pixel column J, and the 3Mth sub-pixel 111 in the 3Y sub-pixel column K, as shown... Figure 12 (1) As shown. Within the second display subframe T2, the second light emission control signal EM2 transmitted by the second light emission control signal line 402 switches to an active level, used to control the light emission of the 3M-1 sub-pixel 111 in the 3Y-2 sub-pixel column I, the 3M sub-pixel 111 in the 3Y-1 sub-pixel column J, and the 3M-2 sub-pixel 111 in the 3Y sub-pixel column K, as shown. Figure 12(2) As shown. Within the third display subframe T3, the third light emission control signal EM3 transmitted by the third light emission control signal line 403 switches to an active level, used to emit light from the 3Mth sub-pixel 111 in the 3Y-2nd sub-pixel column I, the 3M-2nd sub-pixel 111 in the 3Y-1st sub-pixel column J, and the 3M-1st sub-pixel in the 3Y sub-pixel column K, as shown. Figure 12 As shown in (3).

[0125] This design allows for the formation of a pattern where, as the three light-emitting control signals EM1, EM2, and EM3 alternately transition to an active level within their corresponding display sub-frames, groups of three adjacent sub-pixels can be used. Figure 12 The three-row chessboard-style time-sharing drive shown in the figure allows the luminous sub-pixels to be spatially staggered, making it easier for the human eye to integrate them into a continuous image, resulting in a significant improvement in dynamic clarity.

[0126] Figure 14 The diagram shown is a schematic representation of the sub-pixels of a display panel within each time interval according to an embodiment of this application. Figure 15 The diagram shown is a time-division sub-pixel display schematic of a display panel provided in an embodiment of this application.

[0127] In the following embodiments, the sub-pixels 111 in each pixel unit 110 within pixel group 100 are arranged in a cross pattern so that sub-pixels 111 of different colors are arranged adjacently to form a sub-pixel group. For example Figure 14 and Figure 15 In the image, pixel group 100 includes red pixel units, green pixel units, and blue pixel units, and the sub-pixels within the red pixel units, green pixel units, and blue pixel units are arranged in an interleaved manner. Figure 14 For example, in a sub-pixel column, the red sub-pixel R1 in the red pixel unit is arranged first, then the green sub-pixel G1 in the green pixel unit is arranged, then the red sub-pixel R2 in the red pixel unit is arranged, then the green sub-pixel G2 in the green pixel unit is arranged, and so on, with the red sub-pixels and green sub-pixels arranged alternately.

[0128] In one exemplary embodiment, reference is made to Figure 14 and Figure 15 The pixel group 100 has at least one sub-pixel group 120 arranged in rows / columns. The sub-pixel group 120 is composed of a red sub-pixel R in a red pixel unit, a green sub-pixel G in a green pixel unit, and a blue sub-pixel B in a blue pixel unit; wherein the combination of red sub-pixel R and green sub-pixel G is adjacent to blue sub-pixel B.

[0129] Specifically, red sub-pixels R and green sub-pixels G can be combined adjacently in rows / columns to form an RG unit. Blue sub-pixels B are set independently and adjacent to the RG unit. When red sub-pixels R and green sub-pixels G are combined adjacently in rows, blue sub-pixels B can be independently positioned above or below the RG unit. When red sub-pixels R and green sub-pixels G are combined adjacently in columns, blue sub-pixels B can be independently positioned to the left or right of the RG unit. Figure 14 and Figure 15 For example, the red sub-pixel R and the green sub-pixel G are arranged in adjacent columns, and the blue sub-pixel B is set independently to the right of the RG cell.

[0130] In one example, the width / length of the combination of red subpixel R and green subpixel G is the same as the width / length of blue subpixel B. This means that when the RG unit and the independently set blue subpixel B are designed to be exactly the same size, the emission boundaries of the subpixels completely overlap. The persistence of vision generates seamlessly blended rectangular / square light spots, improving the sharpness of text and graphic edges.

[0131] With this design, the red sub-pixel R and the green sub-pixel G are spatially adjacent. Taking advantage of the human eye's high sensitivity to red-green mixing, they can more easily merge into a bright yellow light spot when emitting light in a time-division manner. Moreover, because the red sub-pixel R and the green sub-pixel G are adjacent and emit light in a fused manner, the visual resolution is nearly twice the physical pixel density when displayed.

[0132] In one exemplary embodiment, reference is made to Figure 14 Each pixel unit 110 includes two sub-pixels 111 of the same color, i.e., N=2. Within pixel group 100, two sub-pixel groups 120 are arranged in rows. Sub-pixel group 120 consists of a red sub-pixel R from a red pixel unit, a green sub-pixel G from a green pixel unit, and a blue sub-pixel B from a blue pixel unit; wherein the combination of red sub-pixel R and green sub-pixel G is adjacent to blue sub-pixel B.

[0133] The circuit connection diagram of the light emission control signal line in this embodiment can be reused. Figure 5 To demonstrate. See also Figure 5 The display panel's light emission control signal lines include a first light emission control signal line 401 and a second light emission control signal line 402. The first light emission control signal line 401 is used to transmit a first light emission control signal EM1, and the second light emission control signal line 402 is used to transmit a second light emission control signal EM2.

[0134] The first light emission control signal line 401 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the first target sub-pixel group. The first target sub-pixel group includes the 2M-1th sub-pixel group 120 in odd-numbered pixel group column A and the 2Mth sub-pixel group 120 in even-numbered pixel group column B. The second light emission control signal line 402 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the second target sub-pixel group. The second target sub-pixel group includes the 2Mth sub-pixel group 120 in odd-numbered pixel group column A and the 2M-1th sub-pixel group 120 in even-numbered pixel group column B; where M is an integer greater than or equal to 1.

[0135] Specifically, after the sub-pixels 111 in each pixel unit 110 within pixel group 100 are arranged in a cross pattern, sub-pixels 111 of different colors are arranged adjacently to form a sub-pixel group, that is, red sub-pixel R1, green sub-pixel G1, and blue sub-pixel B1 will form a sub-pixel group 120. And each sub-pixel group 120 is arranged in rows within pixel group 100.

[0136] The timing-driven diagram corresponding to this embodiment can also be referred to. Figure 6 When N=2, the display panel needs to divide the display frame into two display sub-frames to achieve time-division driving, that is, including Figure 6 T1 and T2 are shown. Within the first display subframe T1, the first light emission control signal EM1 transmitted on the first light emission control signal line 401 transitions to an active level, used to control the light emission of the 2M-1th sub-pixel group 120 in odd-numbered pixel group A and the 2Mth sub-pixel group 120 in even-numbered pixel group B, as shown... Figure 14 (1) As shown. Within the second display subframe T2, the second light emission control signal EM2 transmitted by the second light emission control signal line 402 switches to an active level, used to control the light emission of the 2Mth sub-pixel group 120 in the odd-numbered pixel group column A and the 2M-1th sub-pixel group 120 in the even-numbered pixel group column B, as shown. Figure 14 As shown in (2).

[0137] This design allows each sub-pixel group 120 on odd-numbered pixel group A and even-numbered pixel group B to form a structure when the two light-emitting control signals EM1 and EM2 alternately transition to an active level within their corresponding display sub-frames. Figure 14 The chessboard-style time-sharing drive shown in the diagram allows the luminous sub-pixels to be spatially staggered, making it easier for the human eye to integrate them into a continuous image, resulting in a significant improvement in dynamic clarity.

[0138] In one exemplary embodiment, reference is made to Figure 15Each pixel unit 110 includes three sub-pixels 111 of the same color, i.e., N=3. Within pixel group 100, three sub-pixel groups 120 are arranged in rows. Each sub-pixel group 120 consists of a red sub-pixel R from a red pixel unit, a green sub-pixel G from a green pixel unit, and a blue sub-pixel B from a blue pixel unit; wherein the combination of red sub-pixel R and green sub-pixel G is adjacent to blue sub-pixel B.

[0139] The circuit connection diagram of the light emission control signal line in this embodiment can be reused. Figure 8 To demonstrate. See also Figure 8 The light emission control signal lines of the display panel include a first light emission control signal line 401, a second light emission control signal line 402, and a third light emission control signal line 403. The first light emission control signal line 401 is used to transmit a first light emission control signal EM1, the second light emission control signal line 402 is used to transmit a second light emission control signal EM2, and the second light emission control signal line 403 is used to transmit a second light emission control signal EM3.

[0140] The first light emission control signal line 401 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the first target sub-pixel group. The first target sub-pixel group includes the 3M-2nd sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M-1st sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3Mth sub-pixel group 120 in the 3Y pixel group column F. The second light emission control signal line 402 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the second target sub-pixel group. The second target sub-pixel group includes the 3M-1st sub-pixel group 120 in the 3Y-2 pixel group column D, the 3Mth sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3M-2nd sub-pixel group 120 in the 3Y pixel group column F. The third light-emitting control signal line 403 is connected to the control terminal of the switching element 200 corresponding to the sub-pixel 111 of the third target sub-pixel group. The third target sub-pixel group includes the 3Mth sub-pixel group 120 in the 3Y-2nd pixel group column D, the 3M-2nd sub-pixel group 120 in the 3Y-1st pixel group column E, and the 3M-1st sub-pixel group 120 in the 3Y pixel group column F. Here, M is an integer greater than or equal to 1, and Y is an integer greater than or equal to 1.

[0141] Specifically, after the sub-pixels 111 in each pixel unit 110 within pixel group 100 are arranged in a cross pattern, sub-pixels 111 of different colors are arranged adjacently to form a sub-pixel group, that is, red sub-pixel R1, green sub-pixel G1, and blue sub-pixel B1 will form a sub-pixel group 120. And each sub-pixel group 120 is arranged in rows within pixel group 100.

[0142] The timing-driven diagram corresponding to this embodiment can also be referred to. Figure 9 When N=3, the display panel needs to divide the display frame into three display sub-frames to achieve time-division driving, that is, including Figure 9 T1, T2, and T3 are shown. Within the first display subframe T1, the first light emission control signal EM1 transmitted on the first light emission control signal line 401 transitions to an active level, used to control the light emission of the 3M-2nd sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M-1st sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3Mth sub-pixel group 120 in the 3Y pixel group column F, as shown. Figure 15 (1) As shown. Within the second display subframe T2, the second light emission control signal EM2 transmitted by the second light emission control signal line 402 switches to an active level, used to control the light emission of the 3M-1 sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3M-2 sub-pixel group 120 in the 3Y pixel group column F, as shown. Figure 15 (2) As shown. Within the third display subframe T3, the third light emission control signal EM3 transmitted by the third light emission control signal line 403 switches to an active level, used to control the light emission of the 3Mth sub-pixel group 120 in the 3Y-2 pixel group column D, the 3M-2nd sub-pixel group 120 in the 3Y-1 pixel group column E, and the 3M-1st sub-pixel group 120 in the 3Y pixel group column F, as shown. Figure 15 As shown in (3).

[0143] With this design, when the three light-emitting control signals EM1, EM2, and EM3 alternately transition to an active level within their corresponding display sub-frames, each sub-pixel group 120 on three adjacent pixel groups can form a structure like... Figure 15 The three-row chessboard-style time-sharing drive shown in the figure allows the luminous sub-pixels to be spatially staggered, making it easier for the human eye to integrate them into a continuous image, resulting in a significant improvement in dynamic clarity.
