Description

Technical Field

[0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the development of display technology, the application of display panels is becoming more and more extensive, and the corresponding requirements for display panels are also becoming higher and higher.

[0003] The display panel includes multiple columns of sub-pixels, and each data line is connected to a column of sub-pixels. A column of sub-pixels includes sub-pixels of multiple colors, such as red sub-pixels and blue sub-pixels. In traditional pixel circuits, the same column of data lines controls sub-pixels of different colors in a column of sub-pixels. Figure 1 FIG. 1 is a schematic diagram of a structure of a display panel in the prior art. Figure 1 As shown, the display panel includes data lines date1-date4, each corresponding to a column of sub-pixels. Data lines date1 and date2 are connected to sub-pixels of different colors in their corresponding sub-pixel columns. This driving method results in high power consumption. Independent data pixel (SDP) driving technology can separately drive sub-pixels of different colors on the same column, with one data line driving only sub-pixels of one color. This driving method can reduce the power consumption of the display panel. However, the data line wiring method of the existing SDP technology solution has a high risk of anode breakage and is prone to color shift issues. Summary of the Invention

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0046] Figure 2 A schematic diagram of a top view of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the display panel includes: a substrate 110; a plurality of sub-pixels 120, which are located on one side of the substrate 110 and constitute a plurality of sub-pixel columns, including at least one first sub-pixel column P1 and at least one second sub-pixel column P2, the first sub-pixel column P1 and the second sub-pixel column P2 each include sub-pixels 120 of at least two luminous colors, and the sub-pixels of different luminous colors in the first sub-pixel column P1 and the second sub-pixel column P2 are arranged in a different order.

[0047] Multiple data lines 130 are located on the same side of the substrate 110 as the sub-pixels 120, including at least one first data line column D1 and at least one second data line column D2. The first data line column D1 includes a first sub-data line M1 and a second sub-data line M2, and the second data line column D2 includes a third sub-data line M3 and a fourth sub-data line M4. The first sub-data line M1 and the second sub-data line M2 are respectively connected to the sub-pixels 120 of different luminous colors in the first sub-pixel column P1, and the third sub-data line M3 and the fourth sub-data line M4 are respectively connected to the sub-pixels 120 of different luminous colors in the second sub-pixel column P2.

[0048] Among them, in the adjacent first data line column D1 and second data line column D2, the first sub-data line M1 and the corresponding third sub-data line M3 are connected through the first connecting line L1, and the second sub-data line M2 and the corresponding fourth sub-data line M4 are connected through the second connecting line L2; at least one of the first sub-data line M1 and the third sub-data line M3 is connected to the first connecting line L1 through the line changing hole 140; at least one of the second sub-data line M2 and the fourth sub-data line M4 is connected to the second connecting line L2 through the line changing hole 140; the vertical projection of the line changing hole 140 on the substrate 110 does not overlap with the vertical projection of the pixel opening of the sub-pixel 120 on the substrate 110.

[0049] The plurality of sub-pixels 120 constitute a plurality of sub-pixel columns. Each sub-pixel column may include sub-pixels of one color or multiple colors. The plurality of sub-pixels 120 may include sub-pixels of at least three luminous colors, such as red sub-pixels, blue sub-pixels, and green sub-pixels. The sub-pixel columns include a first sub-pixel column P1 and a second sub-pixel column P2, each of which includes sub-pixels 120 of at least two luminous colors, such as Figure 2 As shown, in one example, the first sub-pixel column P1 and the second sub-pixel column P2 both include red sub-pixels and blue sub-pixels. The sub-pixels of different luminous colors in the first sub-pixel column P1 and the second sub-pixel column P2 are arranged in different orders. For example, the sub-pixels 120 of different colors in the first sub-pixel column P1 and the second sub-pixel column P2 can be arranged alternately. Figure 2 The sub-pixels 120 of different colors in the first sub-pixel column P1 and the second sub-pixel column P2 are arranged differently so that the sub-pixels 120 of different colors on the same column can be driven separately.

[0050] Multiple data lines 130 and sub-pixels 120 are located on the same side of the substrate 110. The multiple data lines 130 include at least one first data line column D1 and at least one second data line column D2. Each of the first data line column D1 and the second data line column D2 is respectively arranged corresponding to a sub-pixel column, so that the data lines in the first data line column D1 and the second data line column D2 are connected to the sub-pixels 120 in the corresponding sub-pixel column.

[0051] The first data line column D1 includes a plurality of first sub-data lines M1 and a plurality of second sub-data lines M2, and the plurality of first sub-data lines M1 and the plurality of second sub-data lines M2 are arranged in a column along the second direction Y. The second data line column D2 includes a third sub-data line M3 and a fourth sub-data line M4, and the plurality of third sub-data lines M3 and the fourth sub-data line M4 are also arranged in a column along the second direction Y. The plurality of first data line columns D1 and the second data line columns D2 are arranged along the X direction, and the plurality of first sub-pixel columns P1 and the second sub-pixel columns P2 are also arranged along the X direction. The first sub-data lines M1 and the second sub-data lines M2 are respectively connected to the sub-pixels 120 of different luminous colors in the first sub-pixel column P1. Then, in one first data line column D1, all the first sub-data lines M1 are connected to the sub-pixels 120 of one luminous color, and all the second sub-data lines M2 are connected to the sub-pixels 120 of another luminous color. As Figure 2As shown, the first sub-data lines M1 are all connected to the blue sub-pixels, and the second sub-data lines M2 are all connected to the red sub-pixels. The third sub-data lines M3 and the fourth sub-data lines M4 are respectively connected to the sub-pixels 120 of different luminous colors in the second sub-pixel column P2. Then, in a second data line column D2, all the third sub-data lines M3 are connected to the sub-pixels 120 of one luminous color, and all the fourth sub-data lines M4 are connected to the sub-pixels 120 of another luminous color. Figure 2 As shown, the third sub-data lines M3 are connected to the blue sub-pixels, and the fourth sub-data lines M4 are connected to the red sub-pixels.

[0052] The first data line column D1 represents a column of data lines. However, the sub-data lines in the first data line column D1 are arranged in segments into a column, and the sub-data lines in the second data line column D2 are also arranged in segments into a column. In other words, a column of sub-pixels 120 is connected to the sub-data lines in a column of data lines 130 (data line column), and the sub-data lines corresponding to a column of sub-pixels 120 are also arranged in a column. Therefore, sub-pixels 120 can be connected to sub-data lines nearby, avoiding the need for long traces while implementing SDP driving, reducing the risk of wire breakage, and improving the reliability of the display panel. In some embodiments, sub-pixels 120 include pixel circuitry and a light-emitting element. The pixel circuitry is connected between the sub-data line corresponding to sub-pixel 120 and the light-emitting element. The pixel circuitry may include multiple thin-film transistors and at least one capacitor. For example, the pixel circuitry may have a 2T1C, 3T1C, 4T1C, 5T1C, 5T2C, 6T1C, 7T1C, 8T1C, or 9T2C circuit structure. In the above circuit structure, T refers to a thin-film transistor, and C refers to a capacitor. The number preceding T represents the number of thin-film transistors in the pixel circuit, and the number preceding C represents the number of capacitors in the pixel circuit. The pixel circuit can be connected to the anode of the light-emitting element. A column of light-emitting elements can be arranged adjacent to a corresponding column of sub-data lines. For example, the anodes of the light-emitting elements can be connected to the sub-data lines via the pixel circuit, eliminating the need to connect the anodes to the pixel circuit via long wiring as in the prior art. This can avoid the risk of disconnection of the long anode wiring of the pixels.

[0053] In an embodiment of the present invention, in order to facilitate the connection of data lines connecting sub-pixels 120 of the same luminous color in different columns, a plurality of first connection lines L1 and second connection lines L2 are arranged between adjacent first data line columns D1 and second data line columns D2, so that the first sub-data line M1 and the third sub-data line M3 are connected through the first connection line L1, and the second sub-data line M2 and the fourth sub-data line M4 are connected through the second connection line L2, thereby respectively constituting two data lines connected to sub-pixels 120 of different luminous colors, so that each data line is only connected to sub-pixels 120 of the same luminous color, thereby realizing separate driving of sub-pixels 120 of different colors on the same column, thereby reducing the power consumption of the display panel. In addition, since the embodiment of the present invention does not require the connection method of the long pixel anode wiring in the prior art, the risk of disconnection of the long pixel anode wiring can be avoided, thereby improving the reliability of the data lines for separately driving sub-pixels of different colors on the same column.

[0054] It should be noted that the first sub-data line M1 in a first data line column D1 can be connected to the third sub-data line M3 in the second data line column D2 on its first side or to the third sub-data line M3 in the second data line column D2 on its second side via a first connection line L1. The first side and the second side of the first data line column D1 are respectively adjacent left and right sides along the first direction X. The second sub-data line M2 in a first data line column D1 can be connected to the fourth sub-data line M4 in the second data line column D2 on its first side or to the fourth sub-data line M4 in the second data line column D2 on its second side via a second connection line L2. The same applies to the second data line column D2. This allows for data line connection methods of different shapes, enabling flexible data line connection to sub-pixels 120 of the same luminous color, and providing multiple methods for separately driving sub-pixels 120 of different colors on the same column.

[0055] To facilitate connections between the data lines and the connecting lines, the first and third sub-data lines M1, M3, and the first connecting line L1 are connected via a line-changing hole 140. The second and fourth sub-data lines M2, M4, and the second connecting line L2 are also connected via a line-changing hole 140. Furthermore, the vertical projection of the line-changing hole 140 on the substrate 110 is designed to not overlap with the vertical projection of the pixel opening of the sub-pixel 120 on the substrate 110. That is, the line-changing hole 140 avoids the pixel opening of the sub-pixel 120, thereby preventing color shift problems caused by pits on the sub-pixel 120.

[0056] An embodiment of the present invention provides a display panel, which includes multiple sub-pixels and multiple data lines. The multiple data lines include at least one first data line column and at least one second data line column. The first data line column includes a first sub-data line and a second sub-data line, and the second data line column includes a third sub-data line and a fourth sub-data line. The first sub-data line and the second sub-data line are respectively connected to sub-pixels of different luminous colors in the first sub-pixel column, and the third sub-data line and the fourth sub-data line are respectively connected to sub-pixels of different luminous colors in the second sub-pixel column, so that sub-pixels of different colors on the same column are driven separately to reduce the power consumption of the display panel. In adjacent first data line columns and second data line columns, the first sub-data line and the third sub-data line are connected by a first connecting line, and the second sub-data line and the fourth sub-data line are connected by a second connecting line, so as to realize the connection of data lines connecting sub-pixels of the same luminous color connected on different columns; at least one of the first sub-data line and the third sub-data line is connected to the first connecting line through a line-changing hole, and at least one of the second sub-data line and the fourth sub-data line is connected to the second connecting line through a line-changing hole, and the vertical projection of the line-changing hole on the substrate does not overlap with the vertical projection of the pixel opening of the sub-pixel on the substrate, that is, the line-changing hole avoids the pixel opening of the sub-pixel, thereby preventing color deviation problems caused by pits on the sub-pixel.

[0057] In another embodiment of the present invention, optionally, refer to Figure 2 The sub-pixels 120 connected to the first sub-data line M1 and the third sub-data line M3 emit the same light color, and the sub-pixels 120 connected to the second sub-data line M2 and the fourth sub-data line M4 emit the same light color.

[0058] One end of the first connection line L1 is connected to a first sub-data line M1, and the other end of the first connection line L1 is connected to a third sub-data line M3; the first sub-data line M1 is connected end to end with the first connection line L1 and the third sub-data line M3 to form a first data line; one end of the second connection line L2 is connected to a second sub-data line M2, and the other end of the second connection line L2 is connected to a fourth sub-data line M4; the second sub-data line M2 is connected end to end with the second connection line L2 and the fourth sub-data line M4 to form a second data line.

[0059] Specifically, each of the first sub-data line M1, the third sub-data line M3, the second sub-data line M2 and the fourth sub-data line M4 is connected to at least one sub-pixel 120. The first sub-data line L1 is connected end to end with the first connecting line M1 and the third sub-data line M3 to form a first data line. The second sub-data line M2 is connected end to end with the second connecting line L2 and the fourth sub-data line M4 to form a second data line. The shapes of the first data line and the second data line can be S-shaped, serpentine, or other shapes. The shapes of the first data line and the second data line can be the same or different. The sub-pixels 120 connected to the same first data line have the same luminous color, and the sub-pixels 120 connected to the same second data line have the same luminous color, so that the sub-pixels 120 of the same luminous color on different columns can be driven, and the sub-pixels 120 of different colors on the same column can be driven separately to reduce the power consumption of the display panel. In addition, since the embodiment of the present invention does not need to adopt the connection method of the long anode wiring in the prior art, the risk of the long anode wiring being broken can be avoided, so as to improve the reliability of the data line that separately drives the sub-pixels 120 of different colors on the same column.

[0060] In one example, Figure 2 As shown, the vertical projection of the first sub-data line M1 formed by connecting the first connecting line L1 and the third sub-data line M3 end to end on the substrate 110 is S-shaped, and the vertical projection of the second sub-data line M1 formed by connecting the second connecting line L1 and the fourth sub-data line M4 end to end on the substrate 110 is S-shaped.

[0061] In one example, Figure 2 As shown, the first sub-data lines M1 and the second sub-data lines M2 in the first data line column D1 are arranged alternately; the third sub-data lines M3 and the fourth sub-data lines M4 in the second data line column D2 are arranged alternately.

[0062] In another embodiment of the present invention, referring to Figure 2 The multiple data lines 130 also include multiple third data lines D3; a third data line D3 is arranged between the adjacent first data line column D1 and the second data line column D2; a first sub-data line M1 and a third sub-data line M3 are respectively located on two opposite sides of the third data line D3; a second sub-data line M2 and a fourth sub-data line M4 are respectively located on two opposite sides of the third data line D3.

[0063] Specifically, a first sub-data line M1 and a third sub-data line M3 are respectively located on two opposite sides of the third data line D3, and a second sub-data line M2 and a fourth sub-data line M4 are respectively located on two opposite sides of the third data line D3. Figure 2As shown, the vertical projection of the first connection line L1 on the substrate 110 intersects with the vertical projection of the third data line D3 on the substrate 110 , and the vertical projection of the second connection line L2 on the substrate 110 intersects with the vertical projection of the third data line D3 on the substrate 110 .

[0064] In one example, the display panel also includes at least one third sub-pixel column P3; the third sub-pixel column is located between the first sub-pixel column P1 and the second sub-pixel column P2; the third sub-pixel column P3 includes sub-pixels of one luminous color, each third data line D3 is arranged corresponding to a third sub-pixel column P3, and the third data line D3 is connected to the sub-pixel in the corresponding third sub-pixel column P3.

[0065] Specifically, the third data line D3 is connected to the sub-pixel 120 in the corresponding third sub-pixel column P3, so that the sub-pixel 120 in the third sub-pixel column P3 is driven by the third data line D3.

[0066] In some embodiments of the present invention, the luminous colors of the sub-pixels in the third sub-pixel column P3 are different from the luminous colors of the sub-pixels in the first sub-pixel column P1 and the second sub-pixel column P2.

[0067] In the embodiment of the present invention, reference Figure 2 The multiple sub-pixels 120 include a first sub-pixel, a second sub-pixel and a third sub-pixel, and the first sub-pixel, the second sub-pixel and the third sub-pixel have different luminous colors; the first sub-pixel column P1 and the second sub-pixel column P2 each include a plurality of first sub-pixels and second sub-pixels arranged at intervals, and the third sub-pixel column P3 includes a plurality of third sub-pixels arranged in sequence.

[0068] Among them, the luminous colors of the first sub-pixel, the second sub-pixel and the third sub-pixel are different. The luminous colors of the first sub-pixel, the second sub-pixel and the third sub-pixel can all be one of red, blue and green. For example, the first sub-pixel can be a blue sub-pixel, the second sub-pixel can be a red sub-pixel, and the third sub-pixel can be a green sub-pixel. There is no limitation here.

[0069] Specifically, the first sub-pixel column P1 includes a plurality of first sub-pixels and second sub-pixels arranged at intervals, and the arrangement order of the first sub-pixels and the second sub-pixels in the second sub-pixel column P2 adjacent to the first sub-pixel column P1 is different from the arrangement order in the first sub-pixel column P1, so that the first sub-data line M1 and the third sub-data line M3 are connected, and the second sub-data line M2 and the fourth sub-data line M4 are connected.

[0070] In one example, the first and third sub-data lines M1 and M3 are connected to the first sub-pixel, the second and fourth sub-data lines M2 and M4 are connected to the second sub-pixel, and the third data line D3 is connected to the third sub-pixel in the corresponding third sub-pixel column P3.

[0071] In some examples, the same third data line D3 is connected only to the third subpixel in the corresponding third subpixel column P3. The same first data line, formed by connecting the first sub-data line M1 and the third sub-data line M3 end-to-end via the first connecting line L1, is connected only to the first subpixel in the corresponding first subpixel column P1 and its adjacent second subpixel column P2. The same second data line, formed by connecting the second sub-data line M1 and the fourth sub-data line M4 end-to-end via the second connecting line L2, is connected only to the second subpixel in the corresponding first subpixel column P1 and its adjacent second subpixel column P2. Thus, a single data line connects subpixels of the same color, and can also achieve separate driving of subpixels of different colors in the same column, thereby reducing power consumption of the display panel. Furthermore, because the embodiments of the present invention do not require the connection method of the long anode trace in the prior art, the risk of long anode trace breakage can be avoided, thereby improving the reliability of the data line that separately drives subpixels of different colors in the same column.

[0072] In some examples, as shown in the figure, the first sub-data line M1, the second sub-data line M2, the third sub-data line M3 and the fourth sub-data line M4 extend along the first direction X, the first connection line L1 and the second connection line L2 extend along the second direction Y, and the first direction X is perpendicular to the second direction Y.

[0073] Figure 3 A schematic diagram of a film structure of a display panel provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, in some examples, the first sub-data line M1 , the second sub-data line M2 , the third sub-data line M3 and the fourth sub-data line M4 are located in the first metal layer 150 , and the first connection line L1 and the second connection line L2 are located in the second metal layer 160 .

[0074] In some examples, such as Figure 3 As shown, the display panel further includes a thin film transistor 200 , the source / drain of the thin film transistor 200 is located on the third metal layer 170 , and the first metal layer 150 and the second metal layer 160 are located on a side of the third metal layer 170 away from the substrate 110 .

[0075] The first metal layer 150, the second metal layer 160, and the third metal layer 170 can all be formed of titanium / aluminum / titanium materials. Since the first sub-data line M1, the second sub-data line M2, the third sub-data line M3, and the fourth sub-data line M4 are located in the first metal layer 150, and the first connection line L1 and the second connection line L2 are located in the second metal layer 160, wiring difficulty can be reduced and interference between data lines can be reduced.

[0076] refer to Figure 3The first metal layer 150 is provided with a first sub-data line M1, a second sub-data line M2, a third sub-data line M3, and a fourth sub-data line M4. The second metal layer 160 is provided with a first connecting line L1 and a second connecting line L2. Other wirings, such as a power line, an initialization voltage line, etc., may also be provided in the first metal layer 150 and the second metal layer 160. The first metal layer 150 and the second metal layer 160 are in contact with each other through an opening 1801 on the organic layer 180. To achieve the connection between the first sub-data line M1 and the second sub-data line M2 and the first connecting line L1, and the connection between the third sub-data line M3 and the fourth sub-data line M4 and the second connecting line L2, the opening 1801 on the organic layer 180 can be used as a line switching hole 140. By arranging the data lines and the connecting lines in different film layers, the overlap of the data lines and the connecting lines is avoided, the wiring difficulty is reduced, and the interference between the data lines is reduced. The embodiment of the present invention connects the data lines connecting the same sub-pixels 120 in different pixel columns through the first connecting line L1, the second connecting line L2 and the line-changing hole 140, thereby eliminating the need to adopt the connection method of the long anode line in the prior art and avoiding the risk of the long anode line being broken.

[0077] Figure 4 A schematic diagram of a film layer structure of another display panel provided by an embodiment of the present invention, Figure 4 Detailed description is given of the connection between the first metal layer 150 provided with the first sub-data line M1, the second sub-data line M2, the third sub-data line M3 and the fourth sub-data line M4 and the second metal layer 160 provided with the first connection line L1 and the second connection line L2. Figure 4 As shown, when the first sub-data line M1 or the second sub-data line M2 in the first metal layer 150 is connected to the first connection line L1, or when the third sub-data line M3 or the fourth sub-data line M4 in the first metal layer 150 is connected to the second connection line L2, the first metal layer 150 is not in contact with the sub-pixel anode 1201. At this time, the opening 1801 on the organic layer 180 can be used as a line-changing hole 140. The line-changing hole 140 avoids the pixel opening of the sub-pixel 120, thereby preventing pits from appearing on the sub-pixel anode 1201 of the sub-pixel 120, ensuring that the pixel opening of the sub-pixel 120 is flat, thereby avoiding the problem of color deviation.

[0078] also, Figure 3 The source / drain of the thin film transistor 200 shown in the figure is located in the third metal layer 170, the first metal layer 150 and the second metal layer 160 are located on the side of the third metal layer 170 away from the substrate 110, and the thin film transistor 200 includes a source 201, a drain 204, an active layer 202 and a gate 203, and the second metal layer 160 is connected to the source 201 of the thin film transistor 200.

[0079] Continue to refer Figure 3 and Figure 4 The display panel further includes an organic layer 180 ; the line-changing hole 140 is an opening 1801 on the organic layer 180 ; the first metal layer 150 is located on a first side of the organic layer 180 ; and the second metal layer 160 is located on a second side of the organic layer 180 .

[0080] Specifically, by setting an organic layer 180, the organic layer 180 is formed of an insulating organic material and has an insulating effect, so that the first sub-data line M1 and the second sub-data line M2 are connected to the first connection line L1 through the opening 1801 on the organic layer 180, and the third sub-data line M3 and the fourth sub-data line M4 are connected to the second connection line L2 through the opening 1801 on the organic layer 180. At this time, the opening 1801 on the organic layer 180 serves as a line switching hole 140, which can ensure that the data lines connecting the sub-pixels 120 of the same luminous color in different pixel columns are reliably connected.

[0081] In addition, reference Figure 3 and Figure 4 The display panel includes a pixel definition layer 210, a sub-pixel anode 1201, a first organic layer 220, a first metal layer 150, an organic layer 180, a second metal layer 160, a second organic layer 230, a passivation layer 240, an intermediate layer 250, an interlayer insulating layer 260, a gate insulating layer 270, and a substrate 110. The openings between the pixel definition layers 210 are pixel openings of the sub-pixels 120. The sub-pixels 120 are arranged in the openings between the pixel definition layers 210. The sub-pixels 120 include a sub-pixel anode 1201, a sub-pixel cathode, and a pixel function layer ( Figure 3 and Figure 4 Not shown). Figure 3 The sub-pixel anode 1201 is connected to the source 201 of the thin-film transistor 200 through a through-hole in the first organic layer 220 below, the first metal layer 150, and the second metal layer 160. The second metal layer 160 and the first metal layer 150 are located on either side of the organic layer 180. The first metal layer 150 contacts the second metal layer 160 through the line-changing hole 140 in the organic layer 180 to connect the first sub-data line M1 and the second sub-data line M2 to the first connection line L1, and the third sub-data line M3 and the fourth sub-data line M4 to the second connection line L2. The second metal layer 160 is connected to the source 201 of the thin-film transistor 200 in the third metal layer 170 through a through-hole in the second organic layer 230 and the passivation layer 240. The thin film transistor 200 includes a source electrode 201, a drain electrode 204, an active layer 202, and a gate electrode 203. The source electrode 201 and the drain electrode 204 are connected to the active layer 202 through through-holes in the intermediate layer 250, the interlayer insulating layer 260, and the gate insulating layer 270, respectively. In addition, other film layers such as a buffer layer may be provided between the gate insulating layer 270 and the substrate 110, which are not limited here.

[0082] It should be noted that the first metal layer 150 also includes a third data line D3 , and the third data line D3 in the first metal layer 150 can be directly connected to the source 201 of the thin film transistor 200 through a through hole passing through the underlying film layers.

[0083] Figure 5 A schematic diagram of a local area of ​​a display panel provided by an embodiment of the present invention, with reference to Figure 1 and Figure 5 In the embodiment of the present invention, the projection of the pixel opening of the sub-pixel 120 on the substrate 110 overlaps with the projection of the corresponding first data line column D1 or the second data line column D2 on the substrate 110, so that the sub-pixel anode 1201 of the sub-pixel 120 is connected to the corresponding first data line column D1 or the second data line column D2.

[0084] refer to Figure 5 In some embodiments of the present invention, the display panel further includes a power line D4 and a fan-out line D5. The fan-out line D5 is located between the adjacent first data line column D1 and the third data line D3. The fan-out line D5 is also located between the adjacent second data line column D2 and the third data line D3. There is a hollow area on the power line D4 so that the sub-pixel anode 1201 of the sub-pixel 120 is connected to the corresponding data line in the hollow area. Figure 5 The blue box area in the sub-pixel 120 shown in the figure is the pixel opening. The vertical projection of the pixel opening of the sub-pixel 120 and the sub-pixel anode 1201 on the substrate 110 does not overlap with the vertical projection of the line-changing hole 140 on the substrate 110, that is, the line-changing hole 140 avoids the pixel opening of the sub-pixel 120 to prevent color deviation problems caused by pits on the sub-pixel 120.

[0085] In some embodiments of the present invention, reference Figure 2 and Figure 5 At least one of the first and third sub-data lines M1 and M3 contacts the first connection line L1 through the line change hole 140 , and at least one of the second and fourth sub-data lines M2 and M4 contacts the second connection line L2 through the line change hole 140 .

[0086] Specifically, in the adjacent first data line column D1 and second data line column D2, each first sub-data line M1 can be contacted and connected with the first connection line L1 and the third sub-data line M3 can be contacted and connected with the first connection line L1 through a corresponding line change hole 140, and each second sub-data line M2 can be contacted and connected with the second connection line L2 and the fourth sub-data line M4 can also be contacted and connected with the second connection line L2 through the line change hole 140, so as to connect the data lines in adjacent data line columns, thereby realizing separate driving of sub-pixels of different colors on the same column, so as to reduce the power consumption of the display panel, and there is no need to adopt the connection method of the long anode line in the prior art, which can avoid the risk of broken anode long lines, so as to improve the reliability of the data lines for separately driving sub-pixels 120 of different colors on the same column.

[0087] In some embodiments of the present invention, reference Figure 2 and Figure 5 At least one first connection line L1 and at least one second connection line L2 are provided between a red sub-pixel in the first sub-pixel column P1 and an adjacent blue sub-pixel, and at least one first connection line L1 and at least one second connection line L2 are provided between a red sub-pixel in the second data line column D2 and an adjacent blue sub-pixel. In other embodiments of the present invention, at least one first connection line L1 or at least one second connection line L2 are provided between a red sub-pixel in the first sub-pixel column P1 and an adjacent blue sub-pixel, and at least one first connection line L1 or at least one second connection line L2 are provided between a red sub-pixel in the second data line column D2 and an adjacent blue sub-pixel.

[0088] In another embodiment of the present invention, Figure 2 As shown, the second data line column D2 is located between adjacent first data line columns D1, and the first data line column D1 is located between adjacent second data line columns D2; one first data line column D1 is corresponding to one first sub-pixel column P1, and one second data line column D2 is corresponding to one second sub-pixel column P2.

[0089] Among them, the first connection line L1 and the second connection line L2 between the first data line column D1 and the adjacent second data line column D2 can be arranged crosswise or in the same direction, thereby providing multiple ways to separately drive sub-pixels 120 of different colors on the same column, and being able to separately drive sub-pixels 120 of different colors on the same column to reduce the power consumption of the display panel.

[0090] The first connection line L1 and the second connection line L2 can be arranged to cross each other. Optionally, Figure 6 A schematic diagram of a top view of another display panel provided in an embodiment of the present invention is shown in FIG. Figure 6As shown, a first sub-pixel column P1 and a second sub-pixel column P2 adjacent to each other constitute a sub-pixel column group PN.

[0091] In the same sub-pixel column group PN, the first sub-data line M1 and the third sub-data line M3 connect the sub-pixels 120 of the same luminous color in the sub-pixel column group PN, the second sub-data line M2 and the fourth sub-data line M4 connect the sub-pixels 120 of the same luminous color in the sub-pixel column group PN, and the luminous color of the sub-pixels 120 connected to the first sub-data line M1 and the third sub-data line M3 is different from the luminous color of the sub-pixels connected to the second sub-data line M2 and the fourth sub-data line M4.

[0092] Among them, reference Figure 6 , a sub-pixel column group PN further includes at least two third data columns P3.

[0093] Specifically, in the same sub-pixel column group PN, the first sub-data line M1 and the third sub-data line M3 connect the sub-pixels 120 of the same luminous color in the sub-pixel column group PN, the second sub-data line M2 and the fourth sub-data line M4 connect the sub-pixels 120 of the same luminous color in the sub-pixel column group PN, and the first connection line L1 connecting the first sub-data line M1 and the third sub-data line M3 intersects with the second connection line L2 connecting the second sub-data line M2 and the fourth sub-data line M4, that is, the first sub-data line M1 in a first data line column D1 can be connected to the third sub-data line M3 in the second data line column D2 on its first side through the first connection line L1, and the second sub-data line M2 in the first data line column D1 is also connected to the fourth sub-data line M4 in the second data line column D2 on its first side through the first connection line L1, so that the first connection line L1 and the second connection line L2 intersect. Exemplarily, in the same sub-pixel column group PN, the first sub-data line M1 and the third sub-data line M3 are connected to the blue sub-pixels in the sub-pixel column group PN, the second sub-data line M2 and the fourth sub-data line M4 are connected to the red sub-pixels in the sub-pixel column group PN, and the third data line D3 is connected to the green sub-pixels in the sub-pixel column group PN, thereby achieving separate driving of the sub-pixels 120 of different colors on the same column to reduce the power consumption of the display panel.

[0094] To avoid the problem of increased parasitic capacitance between data lines caused by the crossover of the first connecting line L1 and the second connecting line L2, the first connecting line L1 and the second connecting line L2 can be arranged in the same direction. An embodiment of the present invention further provides a display panel structure in which the first connecting line L1 and the second connecting line L2 have the same direction. Figure 7 A schematic top view of another display panel provided by an embodiment of the present invention is shown. Figure 8 for Figure 7 An enlarged schematic diagram of the top view structure of the first sub-pixel column P1 and Figure 9 A schematic diagram of the structure of a local area of ​​another display panel provided by an embodiment of the present invention, such as Figure 7 and Figure 9 As shown, in some embodiments of the present invention, the display panel further includes a first auxiliary data line column N1 and a second auxiliary data line column N2.

[0095] In the same first data line column D1, the second sub-data line M2 in the first data line column D1 is connected to the fourth sub-data line M4 in the second data line column D2 on the adjacent side through the second connection line L2, and the first sub-data line M1 in the first data line column D1 is connected to the third sub-data line M3 in the second data line column D2 on the other adjacent side through the first connection line L1.

[0096] The first auxiliary data line column N1 is connected to the first sub-data line M1 or the second sub-data line M2 in the first sub-pixel column P1 that is not connected to the second data line column D2, and the second auxiliary data line column N2 is connected to the third sub-data line M3 or the fourth sub-data line M4 in the second sub-pixel column P2 that is not connected to the first sub-pixel column D2.

[0097] In order to make the first connection line L1 and the second connection line L2 run in the same direction and avoid the first connection line L1 and the second connection line L2 from crossing, there are two routing methods, including:

[0098] like Figure 7 As shown in the direction of the first connection line L1 and the second connection line L2, in the same first data line column D1, the second sub-data line M2 in the first data line column D1 is connected to the fourth sub-data line M4 in the second data line column D2 on its second side through the second connection line L2, and the first sub-data line M1 in the first data line column D1 is connected to the third sub-data line M3 in the second data line column D2 on its first side through the first connection line L1, thereby avoiding the intersection of the first connection line L1 and the second connection line L2. The first side can be Figure 7 The left side of the first data line column D1, the second side can be Figure 7 At this time, since the first sub-data line M1 in the leftmost first data line column D1 does not have the second data line column D2 on the first side, the first sub-data lines M1 in the first column cannot all be connected to form one data line. The third sub-data line M3 in the rightmost second data line column D2 in the display panel does not have the first data line column D1 on the second side, resulting in the third sub-data line M3 in the last first column cannot all be connected to form one data line. It is necessary to connect the first sub-data line M1 in the first sub-pixel column P1 that is not connected to the second data line column D2 through the first auxiliary data line column N1. Figure 7 and Figure 8The first sub-data lines M1 in the first column of the first sub-pixel column P1 are connected via the first auxiliary data line column N1, and the second auxiliary data line column N2 is connected to the third sub-data line M3 in the second sub-pixel column P2 that is not connected to the first sub-pixel column D2, thereby achieving separate driving of the sub-pixels 120 of different colors on the same column, thereby reducing the power consumption of the display panel and avoiding the problem of increased parasitic capacitance between the data lines caused by the intersection of the first connection line L1 and the second connection line L2.

[0099] by Figure 7 The first connection line L1 and the second connection line L2 are arranged in opposite directions to the first connection line L1 and the second connection line L2. In the same first data line column D1, the first sub-data line M1 in the first data line column D1 is connected to the third sub-data line M3 in the second data line column D2 on its second side through the first connection line L1, and the second sub-data line M2 in the first data line column D1 is connected to the fourth sub-data line M4 in the second data line column D2 on its first side through the second connection line L2, thereby avoiding the intersection of the first connection line L1 and the second connection line L2. The first side can be Figure 7 The left side of the first data line column D1, the second side can be Figure 7 At this time, since there is no second data line column D2 on the first side of the second sub-data line M2 in the leftmost first data line column D1 in the display panel, all the second sub-data lines M2 in the first column cannot be connected into one data line. Also, there is no first data line column D1 on the second side of the fourth sub-data line M4 in the rightmost second data line column D2 in the display panel, resulting in all the fourth sub-data lines M4 in the last first column cannot be connected into one data line. Therefore, it is necessary to connect the first auxiliary data line column N1 to the second sub-data line M2 in the first first sub-pixel column P1 that is not connected to the second data line column D2, and the second auxiliary data line column N2 to the fourth sub-data line M4 in the second sub-pixel column P2 that is not connected to the first sub-pixel column D2. This allows for separate driving of sub-pixels 120 of different colors on the same column, thereby reducing power consumption of the display panel and avoiding the problem of increased parasitic capacitance between data lines caused by the crossing of the first connection line L1 and the second connection line L2.

[0100] It should be noted that the first auxiliary data line column N1 and the second auxiliary data line column N2 can be arranged side by side with the corresponding data line column, and can also be connected to the corresponding sub-data lines through the first connection line L1 or the second connection line L2 at a certain distance.

[0101] The display panel provided by an embodiment of the present invention includes multiple sub-pixels and multiple data lines. The sub-data lines are respectively connected to sub-pixels of different luminous colors in each pixel column, so that sub-pixels of different colors on the same column are driven separately to reduce the power consumption of the display panel. The line switching holes connecting the data lines and the connecting lines avoid the pixel openings of the sub-pixels, which can prevent color deviation problems caused by pits on the sub-pixels.

[0102] An embodiment of the present invention further provides a display device, Figure 10 A schematic structural diagram of a display device provided by an embodiment of the present invention is shown in FIG. Figure 10 As shown, the display device 200 includes the display panel 100 according to any of the above embodiments.

For example, the display device 200 provided in an embodiment of the present invention can be applied to any product or component with a display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigation system.

[0104] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
