[0045] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] Just as the display panel in the related art has the problem of high power consumption, the inventors have found through careful research that the reason for this technical problem is that the display panel in the related art includes multiple columns of sub-pixels, wherein at least some of the sub-pixel columns contain sub-pixels with different luminous colors, and all sub-pixels in each column of sub-pixels are connected to the same data line. In some cases, such as when the brightness difference of sub-pixels with the same luminous color in the same column of sub-pixels is small, and the brightness difference of sub-pixels with different luminous colors is large, more specifically, when displaying a pure color picture of the primary color corresponding to the first sub-pixel or the second sub-pixel, the voltage on the data line needs to switch back and forth due to the row scanning method. According to the power consumption formula Among them, P is the power consumption, f is the frequency of voltage switching on the data line, c is a constant, and v is the voltage difference before and after switching. When the switching frequency is high, the power consumption on the data line is high, which also leads to higher power consumption of the display panel.

[0048] Based on the above technical problems, the present invention proposes the following solutions:

[0049] Figure 1 A schematic diagram of a display panel according to an embodiment of the present invention is provided. Figure 1 The display panel includes a plurality of sub-pixel groups 1, each sub-pixel group includes a first sub-pixel column 11 and a second sub-pixel column 12, the first sub-pixel column 11 includes at least one first sub-pixel R and a second sub-pixel B; the second sub-pixel column 12 includes at least one first sub-pixel R and at least one second sub-pixel B; the display panel also includes a plurality of data lines, in the same sub-pixel group 1, sub-pixels with the same luminous color in the first sub-pixel column 11 and the second sub-pixel column 12 are connected to the same data line, and sub-pixels with different luminous colors are connected to different data lines.

[0050] Specifically, the display panel includes a display area AA and a non-display area NAA at least partially surrounding the display area AA. A plurality of sub-pixels are provided in the display area AA, specifically, a plurality of first sub-pixels R and a plurality of second sub-pixels B. The light emitting color of the first sub-pixel R may be red, and the light emitting color of the second sub-pixel B may be blue. Of course, the light emitting color of the first sub-pixel R may be blue, and the light emitting color of the second sub-pixel B may be red. The sub-pixels may be OLED (Organic Light Emitting Diode), Micro-LED (Micro Light Emitting Diode) or Mini-LED (Mini Light Emitting Diode), etc.

[0051] The sub-pixels in the display panel are arranged in an array along the row direction X and the column direction Y, and all the sub-pixels in the display panel are divided into a plurality of sub-pixel groups 1. That is, each sub-pixel group 1 includes a plurality of sub-pixels, and the display panel includes a plurality of sub-pixel groups 1 arranged along the row direction X. The array composed of all sub-pixels in the display panel can be understood as being composed of a plurality of sub-pixel groups 1 arranged along the row direction X. Each sub-pixel group 1 includes a first sub-pixel column 11 and a second sub-pixel column 12, that is, each sub-pixel group 1 includes at least two sub-pixel columns. In the first sub-pixel column 11 and the second sub-pixel column 12, the sub-pixels in the same row have different luminous colors, that is, if the sub-pixel in a row of the first sub-pixel column 11 is the first sub-pixel R, then the sub-pixel in the second sub-pixel column 12 in the row is the second sub-pixel B; if the sub-pixel in a row of the first sub-pixel column 11 is the second sub-pixel B, then the sub-pixel in the second sub-pixel column 12 in the row is the first sub-pixel R. This pixel arrangement of the display panel does not produce obvious stripes and has a good display effect.

[0052] In the related art, sub-pixels with different luminous colors in the same column of sub-pixels are all connected to the same data line. In the present embodiment, sub-pixels with the same luminous color in the first sub-pixel column 11 are connected to the same data line, and sub-pixels with different luminous colors are connected to different data lines. Sub-pixels with the same luminous color in the second sub-pixel column 12 are connected to the same data line, and sub-pixels with different luminous colors are connected to different data lines. With such an arrangement, in some cases, such as when the brightness difference of sub-pixels with the same luminous color in the same column of sub-pixels is small, and the brightness difference of sub-pixels with different luminous colors is large, more specifically, when displaying a pure color picture of the primary color corresponding to the first sub-pixel or the second sub-pixel (such as displaying red or displaying blue), the voltage jump amplitude on the same data line is small, or the voltage amplitude remains unchanged (under a pure color picture), thereby achieving the effect of reducing power consumption on the data line.

[0053] The technical solution of this embodiment adopts a display panel including multiple columns of sub-pixel groups, each column of sub-pixel group includes a first sub-pixel column and a second sub-pixel column, the first sub-pixel column and the second sub-pixel column both include multiple first sub-pixels and second sub-pixels alternately arranged along the column direction, the first sub-pixel and the second sub-pixel emit different colors; and the sub-pixels in the same row in the first sub-pixel column and the second sub-pixel column are different; the display panel also includes multiple data lines, in the same sub-pixel group, the sub-pixels with the same luminous color in the first sub-pixel column and the second sub-pixel column are connected to the same data line, and the sub-pixels with different luminous colors are connected to different data lines. Since the sub-pixels connected to the same data line emit the same color, when displaying certain pictures, such as pure color pictures, the voltage on the data line does not need to jump, thereby greatly reducing the power consumption of the display panel.

[0054] It should be noted that the data lines of the display panel are connected to the corresponding sub-pixels through the pixel driving circuit. The pixel driving circuit can be a pixel driving circuit including two transistors and one capacitor, and this circuit is also called a "2T1C" pixel driving circuit. Of course, by analogy, it can also be a "4T1C" pixel driving circuit, a "6T1C" pixel driving circuit or a "7T1C" pixel driving circuit. This embodiment only briefly introduces the "7T1C" pixel driving circuit.

[0055] like Figure 2 As shown, Figure 2 A circuit structure diagram of a pixel driving circuit provided in an embodiment of the present invention, the pixel driving circuit includes a driving transistor T1, a data writing transistor T2, a threshold compensation transistor T3, a first initialization transistor T4, a first light emission control transistor T5, a second light emission control transistor T6, a second initialization transistor T7 and a storage capacitor Cst. Among them, the first end of the data writing transistor T2 is electrically connected to the data line Vdata, the second end of the data writing transistor T2 is electrically connected to the first end of the driving transistor T1, and the control end of the data writing transistor T2 is electrically connected to the second scanning signal line S2. The second end of the driving transistor T2 is electrically connected to the first end of the threshold compensation transistor T3, and the control end of the driving transistor T2 is electrically connected to the first end of the storage capacitor Cst and the second end of the threshold compensation transistor T3. The second end of the storage capacitor Cst is electrically connected to the first power signal line ELVDD. The control end of the threshold compensation transistor T3 is electrically connected to the second scanning signal line S2. The first end of the first initialization transistor T4 is electrically connected to the first initialization signal line Vref1, the second end of the first initialization transistor T4 is electrically connected to the control end of the driving transistor T1, and the control end of the first initialization transistor T4 is electrically connected to the first scanning signal line S1. The first end of the first light-emitting control transistor T5 is electrically connected to the first end of the driving transistor T1, the second end of the first light-emitting control transistor T5 is electrically connected to the first power signal line ELVDD, and the control end of the first light-emitting control transistor T5 is electrically connected to the enable signal line EM. The first end of the second light-emitting control transistor T6 is electrically connected to the first end of the driving transistor T1, the second end of the second light-emitting control transistor T6 is electrically connected to the first end of the sub-pixel 102, and the control end of the second light-emitting control transistor T6 is electrically connected to the enable signal line EM. The first end of the second initialization transistor T7 is electrically connected to the second initialization signal line Vref2, the second end of the second initialization transistor T7 is electrically connected to the first end of the sub-pixel 102, and the control end of the second initialization transistor T7 is electrically connected to the first scanning signal line S1. The second end of the sub-pixel 102 is electrically connected to the second power signal line ELVSS.

[0056] The working process of the pixel driving circuit includes:

[0057] Initialization phase, in this phase, the first scanning signal line S1 controls the first initialization transistor T4 and the second initialization transistor T7 to be turned on. The first initialization signal on the first initialization signal line Vref1 initializes the voltage of the control end of the driving transistor T1. The second initialization signal on the second initialization signal line Vref2 initializes the voltage of the first end of the sub-pixel 102.

[0058] In the compensation writing stage, the second scanning signal line S2 controls the data writing transistor T2 and the threshold compensation transistor T3 to be turned on. The data voltage on the data line Vdata is written to the control end of the driving transistor T1 after passing through the driving transistor and the threshold compensation transistor. In this stage, the threshold compensation of the driving transistor T1 is completed.

[0059] In the light emitting stage, the enable signal line EM controls the first light emitting control transistor T5 and the second light emitting control transistor T6 to be turned on. The driving transistor T1 generates a driving current, and the sub-pixel 102 emits light in response to the driving current.

[0060] Optionally, continue to refer to Figure 1 , the plurality of data lines include a plurality of first data lines D1 and a plurality of second data lines D2; each sub-pixel group corresponds to a first data line D1 and a second data line D2. In the same sub-pixel group 1, the first sub-pixels R in the first sub-pixel column 11 and the second sub-pixel column 12 are connected to the same first data line D1, and the second sub-pixels B in the first sub-pixel column 11 and the second sub-pixel column 12 are connected to the same second data line D2; the first data line D1 includes a first sub-data line D11 and a second sub-data line D12 extending along the column direction Y and arranged along the row direction X; the first sub-data line D11 is connected to the first sub-pixel R in the first sub-pixel column 11, and the second sub-data line D12 is connected to the first sub-pixel R in the second sub-pixel column 12; the first data line D1 also includes at least one A first connection line D13, the first connection line D13 connects the corresponding first sub-data line D11 and the second sub-data line D12; the second data line D2 includes a third sub-data line D21 and a fourth sub-data line D22 extending along the column direction Y and arranged along the row direction X, the third sub-data line D21 is connected to the second sub-pixel B in the first sub-pixel column 11, and the fourth sub-data line D22 is connected to the second sub-pixel D22 in the second sub-pixel column 12; the second data line D2 also includes at least one second connection line D23, the second connection line D23 connects the corresponding third sub-data line D21 and the fourth sub-data line D22.

[0061] Specifically, the luminous colors of the first sub-pixel R and the second sub-pixel B are different; the first sub-pixel column 11 includes a plurality of first sub-pixels R and a plurality of second sub-pixels B arranged along the column direction Y, and the first sub-pixels R and the second sub-pixels B are arranged alternately; the second sub-pixel column 12 includes a plurality of first sub-pixels R and a plurality of second sub-pixels B arranged along the column direction Y, and the first sub-pixels R and the second sub-pixels B are arranged alternately; along the row direction X, the sub-pixels in the first sub-pixel column 11 and the second sub-pixel column 12 located in the same row are different. That is to say, if one of the two sub-pixels in the first sub-pixel column 11 and the second sub-pixel column 12 is located in the same row, the other is the second sub-pixel B. In this embodiment, each column of sub-pixels is correspondingly provided with two sub-data lines, wherein the first sub-pixel column 11 is correspondingly provided with a first sub-data line D11 and a third sub-data line D21; the second sub-pixel column 12 is correspondingly provided with a second sub-data line D12 and a fourth sub-data line D22. The corresponding meaning in this embodiment is that the corresponding sub-pixels in the column of sub-pixels are connected to the sub-data line. In this embodiment, the first data line and the second data line both include sub-data lines corresponding to each column of sub-pixels and extending along the column direction, so that the wiring in the display panel is relatively neat and compact, and the space in the display panel can be reasonably utilized. In addition, the corresponding sub-data lines are connected by connecting lines to form at least a partial structure of the data line; the connecting lines can be located in the display area AA, so that the frame can be reduced; the connecting lines can also be located in the non-display area NAA, so that the voltages at various locations of the data lines can be more balanced.

[0062] In addition, since the sub-pixels in the same row in the first sub-pixel column 11 and the second sub-pixel column 12 emit different colors, and the first sub-pixels and the second sub-pixels in the first sub-pixel column 11 and the second sub-pixel column 12 are arranged alternately. In other words, if the first sub-pixel R in the first sub-pixel column 11 is located in an odd row and the second sub-pixel B is located in an even row; then the first sub-pixel R in the second sub-pixel column 12 is located in an even row and the second sub-pixel B is located in an odd row. Furthermore, the first data line connects the first sub-pixel R in the odd row in the first sub-pixel column 11 and the first sub-pixel R in the even row in the second sub-pixel column 12; the second data line connects the second sub-pixel B in the even row in the first sub-pixel column 11 and the second sub-pixel B in the odd row in the second sub-pixel column 12. Furthermore, all sub-pixels connected to the first data line are located in different rows, and all sub-pixels connected to the second data line are also located in different rows. When a row scanning display mode is adopted (i.e., when a row is scanned, the data line transmits the data signal corresponding to the sub-pixels in the row), all sub-pixels on the same data line can be scanned and displayed row by row. However, if two sub-pixels connected to a data line are located in the same row, when the row corresponding to the two sub-pixels is scanned, the data line cannot transmit different data voltages to the two sub-pixels, and row by row scanning cannot be implemented.

[0063] Optionally, the first sub-data line D11, the second sub-data line D12, the third sub-data line D21 and the fourth sub-data line D22 are in the same layer. The first connecting line D13 and the first sub-data line D11 can be in the same layer or in different layers, and the second connecting line D23 and the first sub-data line D11 can be in the same layer or in different layers.

[0064] Optionally, continue to refer to Figure 1 , the first sub-data line D11 and the third sub-data line D21 corresponding to the same first sub-pixel column 11 overlap with the projection of the first sub-pixel column 11 on the plane perpendicular to the thickness direction of the display panel; the second sub-data line D12 and the fourth sub-data line D22 corresponding to the same second sub-pixel column 12 overlap with the projection of the second sub-pixel column 12 on the plane perpendicular to the thickness direction of the display panel. The plane perpendicular to the thickness direction of the display panel is, for example, the substrate in the display panel. In this embodiment, the sub-data line can be understood as penetrating the corresponding sub-pixel column arrangement. Of course, the data line and the sub-pixel are located in different layers, and penetration means penetrating the projection along the thickness direction.

[0065] Optionally, Figure 3 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 3 , the first sub-data line D11 and the third sub-data line D21 corresponding to the same first sub-pixel column 11 are arranged on the same side or different sides of the pixel driving circuit corresponding to the first sub-pixel column 11. The second sub-data line D12 and the fourth sub-data line D22 corresponding to the same second sub-pixel column 12 are arranged on the same side or different sides of the pixel driving circuit corresponding to the second sub-pixel column 12.

[0066] Specifically, for ease of understanding, the pixel driving circuit for driving the first sub-pixel R is marked as the first pixel driving circuit R1, and the pixel driving circuit for driving the second sub-pixel B is marked as the second pixel driving circuit B1. The circuit structures of the first pixel driving circuit R1 and the second pixel driving circuit B1 are the same. All pixel driving circuits corresponding to the sub-pixel group 1 are defined as the pixel driving circuit group 1p. The pixel driving circuit column corresponding to the first sub-pixel column 11 is defined as the first pixel driving circuit column 11p, and the pixel driving circuit column corresponding to the second sub-pixel column 12 is defined as the second pixel driving circuit column 12p. Figure 3As shown in the figure, the sub-data lines corresponding to the same column of pixel driving circuits are located on the same side of the pixel driving circuits in the column. This design can shorten the distance between the sub-data lines and the corresponding pixel driving circuits, reduce resistance, and reduce power consumption. When the sub-data lines corresponding to the same column of pixel driving circuits are located on different sides of the pixel driving circuits in the column, since the pixel driving circuits in the same column are repeatedly designed in the layout design, that is, the position of the pixel driving circuit used to connect the sub-data lines is located in the same part of the pixel driving circuit; this will result in a shorter connection between one sub-data line and the pixel driving circuit, and a longer connection between the other sub-data line and the pixel driving circuit, and the power consumption of the connection is higher; but this design makes the distance between the sub-data lines corresponding to the sub-pixels in the same column farther, so this design can reduce the signal crosstalk on the sub-data lines.

[0067] In order to more clearly illustrate the structure of each data line, the following figures will illustrate the pixel driving circuit and the data line instead of the sub-pixel.

[0068] Optionally, Figure 4 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 4 At least part of the first sub-data line D11, at least part of the second sub-data line D12 and two first connecting lines D13 form a first closed structure; at least part of the third sub-data line D21, at least part of the fourth sub-data line D22 and two second connecting lines D23 form a second closed structure.

[0069] Specifically, the closed structure described in this embodiment refers to a structure formed by two connection lines and a sub-data line. Providing a closed structure on the data line is equivalent to increasing the width of the data line, thereby reducing the impedance of the data line and further reducing the power consumption of the data line.

[0070] Optionally, in some embodiments, Figure 4 As shown, the first connection line D13 and the second connection line D23 extend along the row direction X. The first connection line D13 and the second connection line D23 are easier to route, thereby reducing the difficulty of routing. The closed structure described in this embodiment is a rectangular structure.

[0071] Alternatively, in some other embodiments, Figure 5 As shown, Figure 5 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention. In this embodiment, at least one of the first connecting line D13 and the second connecting line D23 extends in a direction that intersects both the row direction and the column direction. And the connecting lines in the same closed structure may cross or not cross, and when they cross, the closed structure is in an "∞" shape, and when they do not cross, the closed structure is preferably a parallelogram.

[0072] In addition, it should be noted that there may be multiple first connection lines D13 in the first data line D1, that is, multiple first closed structures may be formed, thereby further reducing the impedance of the first data line D1. Similarly, there may be multiple first connection lines D23 in the second data line D2, that is, multiple second closed structures may be formed, thereby further reducing the impedance of the second data line D2.

[0073] Optionally, continue to refer to Figure 3 , the first closed structure includes all of the first sub-data line D11 and all of the second sub-data line D12; the second closed structure includes all of the third sub-data line D21 and all of the fourth sub-data line D22. Compared with the design in which there are parts of the sub-data line that do not form a closed structure, the arrangement of this embodiment can further reduce the total impedance of the data line through the calculation of the series-parallel relationship of each part, thereby further reducing the power consumption of the data line.

[0074] Optionally, continue to refer to Figure 3 The first sub-data line D11, the second sub-data line D12, the third sub-data line D21 and the fourth sub-data line D22 extend from the display area AA to the non-display area NAA; the first connection line D13 in the first closed structure is arranged in the non-display area NAA; the second connection line D23 in the second closed structure is arranged in the non-display area NAA.

[0075] Specifically, along the column direction Y, the non-display area NAA may include an upper frame area and a lower frame area located on both sides of the display area AA, wherein the lower frame area can be used to bind the driver chip. Of the two first connecting lines D13 constituting the first closed structure, one is arranged in the upper frame area, and the other is arranged in the lower frame area. Of the two second connecting lines D23 constituting the second closed structure, one is arranged in the upper frame area, and the other is arranged in the lower frame area. The arrangement of this embodiment enables the connecting line to be arranged in the non-display area, which can reduce the number of wirings in the display area, thereby reducing the wiring difficulty of the display area. Optionally, the driver chip can be connected to the first connecting line D13 and the second connecting line D23 located in the lower frame area through corresponding signal lines.

[0076] Optionally, refer to Figure 3 , along the row direction X, the first sub-data line D11, the third sub-data line D21, the second sub-data line D12 and the fourth sub-data line D22 corresponding to the same sub-pixel group 1 are arranged in sequence.

[0077] Specifically, in this embodiment, the first sub-data line D11 and the third sub-data line D21 are connected to the first sub-pixel column 11; and the second sub-data line D12 and the fourth sub-data line D22 are connected to the second sub-pixel column 12. The arrangement of this embodiment makes the distance between the two sub-data lines connected to the first sub-pixel column close, and the distance between the two sub-data lines connected to the second sub-pixel column is close. When displaying, the voltage drop of the data voltage corresponding to the sub-pixels in the same column is close, which can improve the problem of uneven display.

[0078] Furthermore, the length of the first closed structure can be set to be the same as the perimeter of the second closed structure. This arrangement makes the impedance of the first data line D1 and the second data line D2 closer, so that the data voltage received by each sub-pixel in the display panel can be more uniform, thereby further improving the display unevenness.

[0079] Optionally, Figure 6 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 6 Along the row direction, the first sub-data line D11, the third sub-data line D21, the fourth sub-data line D22 and the second sub-data line D12 corresponding to the same sub-pixel group are arranged in sequence; along the thickness direction of the display panel, the projection of the second closed structure is located within the outline of the projection of the first closed structure.

[0080] Specifically, in this embodiment, the first closed structure can be understood as a larger closed structure, and the second closed structure can be understood as a smaller closed structure. Figure 3 In the implementation method of the present embodiment, the first closed structure and the second closed structure intersect at two points, which means that two windings are required, thereby increasing the design difficulty. In contrast, in the method of this embodiment, the first closed structure and the second closed structure do not intersect, so there is no need for winding, which makes wiring easier. Of course, it should be noted that in the structure of this embodiment, the signal line between the second closed structure and the driver chip needs to be wound.

[0081] Optionally, Figure 7 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 7 The first data line D1 includes a first connection line D13, and the second data line D2 includes a second connection line D23. This arrangement reduces the number of wirings in each data line, which is more conducive to wiring.

[0082] Optionally, along the row direction, the first connection line D13 and the second connection line D23 are not collinear. In this embodiment, the first connection line D13 and the second connection line D23 both extend along the row direction X. The first connection line D13 and the second connection line D23 are not on a straight line, that is, the first connection line D13 and the second connection line D23 are parallel and non-intersecting line segments. In this way, the first connection line D13 and the second connection line D23 will not overlap, and there is no need to perform winding, thereby reducing the difficulty of wiring.

[0083] Optionally, along the column direction Y, the first connection line D13 and the second connection line D23 are arranged in the non-display area NAA on different sides of the display area AA. The first connection line D13 can be arranged in the upper frame area, and the second connection line D23 can be arranged in the lower frame area. The first connection line D13 can be arranged not to overlap with the third sub-data line D21 and the fourth sub-data line D22, and the second connection line D23 can be arranged not to overlap with the first sub-data line D11 and the second sub-data line D12, so as to reduce interference between data lines.

[0084] Alternatively, in some other embodiments, such as Figure 8 As shown, Figure 8 A schematic diagram of another display panel structure provided by an embodiment of the present invention: The first connection line D13 and the second connection line D23 are arranged in the display area AA, so that the size of the non-display area NAA can be reduced, that is, the frame of the display panel can be reduced.

[0085] Optionally, refer to Figures 1 to 8 The sub-pixel group 1 also includes a third sub-pixel column 13 arranged between the first sub-pixel column 11 and the second sub-pixel column 12, and a third sub-pixel column 13 on the side of the second sub-pixel column 12 away from the first sub-pixel column 11; each third sub-pixel column 13 includes a plurality of third sub-pixels G, and the third sub-pixels G have different luminous colors from the first sub-pixels R and the second sub-pixels B; each third sub-pixel column G is correspondingly provided with a third data line D3, and the third sub-pixels in the same third sub-pixel column are connected to the same third data line D3; different third sub-pixel columns are connected to different third data lines D3.

[0086] Specifically, the luminous color of the third sub-pixel G may be green. The display panel realizes full-color display by setting the first sub-pixel R, the second sub-pixel B and the third sub-pixel G. Herein, the pixel driving circuit corresponding to the third sub-pixel G is marked as the third pixel driving circuit G1, and the pixel driving circuit column corresponding to the third sub-pixel column 13 is marked as the third pixel driving circuit column 13p. The third pixel driving circuit G1 has the same structure as the first pixel driving circuit R1 and the second pixel driving circuit B1. Since the sub-pixels contained in the third sub-pixel column 13 all have the same luminous color, each third sub-pixel column may only correspond to one data line, so that the power consumption of the pure color picture corresponding to the color of the third sub-pixel is low.

[0087] Optionally, Fig. 9 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Fig. 9 Each third sub-pixel column is correspondingly provided with an auxiliary signal line F1.

[0088] Specifically, through the above analysis, it can be seen that the first sub-pixel column and the second sub-pixel column both need to set two sub-data lines, while the third sub-pixel column only needs to set one data line accordingly. The routing density uniformity of the film layer where the data lines are located is poor, and mura (uneven display) will appear when the screen is turned off.

[0089] Preferably, the auxiliary signal line F1 is in the same layer as the third data line D3. In this embodiment, the auxiliary signal line F1 is used to compensate for the uniformity of the wiring density of the film layer where the data lines are located in the display panel, and improve the off-screen mura situation.

[0090] Optionally, the auxiliary signal line F1 and the corresponding third data line D3 are located on the same side or different sides of the pixel driving circuit corresponding to the third sub-pixel column 13. Specifically, the positional relationship between the auxiliary signal line F1, the corresponding third data line D3 and the third pixel driving circuit column is the same as the positional relationship between the first pixel driving circuit column and the corresponding two sub-data lines, so that the routing density uniformity of the film layer where the data lines are located is better. The same position refers to that the two signal lines are located on the same side or different sides of the pixel driving circuit column. Of course, when the third data line D3 and the auxiliary signal line F1 are located on the same side of the third pixel driving circuit column 13p, the third data line D3 can be set between the auxiliary signal line F1 and the third pixel driving circuit column 13p, which can avoid the need for winding when the third data line D3 is connected to the third pixel driving circuit.

[0091] Optionally, a fixed potential is connected to the auxiliary signal line F1. If the auxiliary signal line F1 is not connected to any potential, parasitic capacitance may be formed with other signal lines, thereby generating signal coupling and increasing power consumption. By connecting to a fixed potential, the risk of signal coupling with other signal lines can be reduced, thereby reducing power consumption. Optionally, the auxiliary signal line F1 can be connected to the corresponding third data line D3, or to one of the first power signal line, the second power signal line and the first initialization signal line, and of course, it can also be used as a winding for each scanning signal line or enable signal line.

[0092] The embodiment of the present invention further provides a display device, such as Fig.10 As shown, Fig.10 A schematic diagram of the structure of a display device provided in an embodiment of the present invention. The display device includes a display panel provided in any embodiment of the present invention.
