Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described through embodiments with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of a display panel according to an embodiment of the present invention. The display panel provided by the embodiment comprises: the display device comprises a hollow area 11, a first non-display area 12 positioned on the periphery of the hollow area 11, a display area 13 positioned on the periphery of the first non-display area 12 and a second non-display area 14 positioned on the periphery of the display area 13, wherein the display area 13 comprises a plurality of sub-pixels 13a and a plurality of data lines 13b arranged along a first direction X, the plurality of sub-pixels 13a comprise m colors, the colors of the sub-pixels 13a in a column are the same, m is greater than or equal to 3, one data line 13b is electrically connected with the sub-pixels 13a in a corresponding column, each data line 13b overlapped with the first non-display area 12 comprises a first data lead 131 positioned in the first non-display area 12 and a second data lead 132 positioned in the display area 13 and extending along a second direction Y, the first direction X is crossed with the second direction Y, each first data lead 131 extends in a winding mode to pass through the first non-display area 12 on the periphery of the hollow area 11, in the first non-display area 12, at least two first data wires 131 for supplying data signals to the same color sub-pixels 13a are adjacently disposed in the front projection of the display panel.
In this embodiment, the display area 13 of the display panel surrounds the hollow area 11, the hollow area 11 may be used to place optical devices such as a camera of the display panel, so as to implement a full screen of the display panel, the periphery of the hollow area 11 is provided with the first non-display area 12, and the first non-display area 12 may be used to place the first data lead 131 and the pixel circuit connected to the sub-pixel 13 a. Specifically, the corresponding regions of the array substrate and the color film substrate of the display panel to be set as the hollow regions 11 may be simultaneously hollowed out to form the hollow regions 11 surrounded by the display region 13 in the display panel; optionally, part of the film layers of the array substrate and the color filter substrate of the display panel to be set as corresponding regions of the hollow region 11 are hollowed out to form the hollow region 11 surrounded by the display region 13 in the display panel; instead of hollowing out the array substrate and/or the color filter substrate of the display panel and a part of the film layer thereof, signal lines and the like to be set as corresponding regions of the hollow region 11 may be directly replaced with transparent materials, so as to form the hollow region 11 surrounded by the display region 13 in the display panel. The hollow area 11 of the optional display panel is circular, and in other embodiments, the hollow area of the optional display panel is in other shapes such as square, and the shape of the hollow area of the display panel is not particularly limited in the present invention.
In the present embodiment, the display region 13 includes a plurality of sub-pixels 13a and a plurality of data lines 13b arranged in the first direction X. Since the display area 13 surrounds the hollow area 11 and the first non-display area 12, and one data line 13b is electrically connected to one column of sub-pixels 13a, at least one data line 13b of the plurality of data lines 13b of the display area 13 overlaps the first non-display area 12. Wherein each of the data lines 13b not overlapping the first non-display area 12 extends in the second direction Y.
In this embodiment, each data line 13b overlapped with the first non-display area 12 is divided into a first data lead 131 located in the first non-display area 12 and a second data lead 132 located in the display area 13 and extending along the second direction Y, and as the known structure that the first data lead 131 is not disposed in the hollow area 11, the first non-display area 12 surrounds the hollow area 11, and therefore each first data lead 131 can extend in a winding manner to pass through the first non-display area 12 on the periphery of the hollow area 11. Here, the winding manner specifically means that the first data lead 131 extends along the shape of the hollow area 11 to pass through the first non-display area 12 at the periphery of the hollow area 11, for example, as shown in fig. 1, the hollow area 11 may be a circular hole area, and then the first data lead 131 extends in an arc manner in the first non-display area 12.
In this embodiment, in the first non-display area 12, at least two first data wires 131 providing data signals to the sub-pixels 13a with the same color are adjacently disposed in the front projection of the display panel, and then the at least two first data wires 131 adjacently disposed in the front projection of the display panel do not overlap. Due to the fact that the size of the first non-display area is small, crosstalk and sub-pixel charging coupling effects exist between adjacent data lines when the data lines corresponding to the hollow areas are arranged in the first non-display area, and display vertical stripes are generated on the display panel. Based on this, in this embodiment, at least two first data leads 131 for providing data signals to the same-color sub-pixels 13a are adjacently disposed in the front projection of the display panel, and the same-color sub-pixels 13a in a row of the sub-pixels 13a are charged simultaneously, so that the at least two first data leads 131 adjacently disposed simultaneously provide data signals to the corresponding same-color sub-pixels 13a, and accordingly, the sub-pixel charging coupling effect and crosstalk between the at least two first data leads 131 adjacently disposed are reduced, and thus, the phenomenon of vertical stripes existing in a severe picture in the prior art can be improved. It should be noted that the sub-pixels 13a are disposed in the display region 13, and the data lines 13b are electrically connected to the sub-pixels 13a in a corresponding column respectively to provide data signals to each of the sub-pixels 13a in the corresponding column. For the first data lead 131 extending in the first non-display area 12, since the hollow area 11 is not provided with the sub-pixel 13a, the first data lead 131 does not need to be connected with the sub-pixel 13a, and for the second data lead 132 extending in the display area 13, the second data lead 132 is directly and electrically connected with the corresponding column of sub-pixels 13 a.
In the display panel provided by this embodiment, the display area includes a first non-display area, the first non-display area surrounds the hollow area, a second non-display area is further disposed on the periphery of the display area, each data line overlapped with the first non-display area includes a first data lead located in the first non-display area and a second data lead located in the display area and extending along the second direction, each first data lead extends in a winding manner to pass through the first non-display area on the periphery of the hollow area, in the first non-display area, at least two first data leads providing data signals for subpixels of the same color are adjacently disposed in a forward projection of the display panel, and then the adjacent two first data leads do not overlap in the forward projection of the display panel. In this embodiment, at least two first data leads providing data signals to subpixels of the same color are adjacently disposed in an orthogonal projection of the display panel, and subpixels of the same color in a row of subpixels are charged simultaneously, so that the at least two first data leads adjacently disposed provide data signals to corresponding subpixels of the same color at the same time, and accordingly, a charging coupling effect and crosstalk between the at least two first data leads are reduced, so that a vertical streak phenomenon existing in a severe picture in the prior art can be improved.
For example, on the basis of the above technical solution, it may be selected that m is 3 as shown in fig. 2, a row of sub-pixels 13a is repeatedly arranged in sequence according to the order of a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, and in the first direction X, 6 data lines 13B corresponding to every 6 adjacent columns of sub-pixels 13a are a data line repeating unit 13 c; in each data line repeating unit 13c, two first data lead lines 131 corresponding to two rows of red subpixels R are adjacently disposed in the front projection of the display panel, two first data lead lines 131 corresponding to two rows of green subpixels G are adjacently disposed in the front projection of the display panel, and two first data lead lines 131 corresponding to two rows of blue subpixels B are adjacently disposed in the front projection of the display panel.
In this embodiment, one row of the sub-pixels 13a includes a plurality of pixel units, and one pixel unit includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B sequentially arranged. The 6 data lines 13b corresponding to two adjacent pixel units serve as a data line repeating unit 13 c. For each data line repeating unit 13c, the two first data leads 131 corresponding to the two rows of same-color subpixels 13a are disposed adjacent to each other in the orthogonal projection of the display panel, and then the two first data leads 131 can simultaneously provide data signals to the corresponding same-color subpixels 13a, so that the subpixel charging coupling effect and crosstalk between the at least two first data leads 131 are correspondingly reduced, and thus the phenomenon of vertical stripes existing in a severe picture in the prior art can be improved. In addition, in the first non-display area 12, the first data leads 131 are arranged in the manner of the data line repeating unit 13c, which is convenient for wiring and manufacturing, and reduces the difficulty of process manufacturing.
Optionally, as shown in fig. 2, in the first non-display area 12, the 6 first data leads 131 of each data line repeating unit 13c are sequentially arranged in the orthographic projection of the display panel, and the corresponding sub-pixels 13a are a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a blue sub-pixel B. In other embodiments, the color ordering of the subpixels corresponding to the 6 first data leads of each data line repeating unit may also be GGRRBB, and those skilled in the art can understand that, on the basis of ensuring that the first data leads corresponding to the subpixels of the same color in the 6 first data leads of each data line repeating unit are adjacently arranged, the color ordering of the subpixels corresponding to each data line repeating unit may be changed, which is not specifically limited in the present invention.
Optionally, as shown in fig. 2, in the first non-display area 12, two first data leads 131 in each data line repeating unit 13c for providing data signals to the sub-pixels 13a of the same color do not overlap on the orthographic projection of the display panel, so that the coupling capacitance between the two first data leads 131 is reduced, and the sub-pixel charging coupling effect and crosstalk between the two first data leads 131 are further reduced, thereby further improving the vertical stripe phenomenon in the severe picture in the prior art.
Illustratively, on the basis of any of the above embodiments, the plurality of sub-pixels 13a shown in fig. 3 may include a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, the plurality of first data leads 131 for providing the data signal to the red sub-pixel R in the first non-display region 12 are adjacently disposed in the front projection of the display panel, the plurality of first data leads 131 for providing the data signal to the green sub-pixel G in the first non-display region 12 are adjacently disposed in the front projection of the display panel, and the plurality of first data leads 131 for providing the data signal to the blue sub-pixel B in the first non-display region 12 are adjacently disposed in the front projection of the display panel. Optionally, the plurality of first data wires 131 in the first non-display region 12 are sequentially arranged in the orthographic projection of the display panel according to the sequence of the plurality of first data wires for providing the data signal to the red sub-pixel R, the plurality of first data wires for providing the data signal to the green sub-pixel G, and the plurality of first data wires for providing the data signal to the blue sub-pixel B.
In this embodiment, in the first non-display area 12, the plurality of first data leads 131 providing the data signals to the same-color sub-pixels 13a are adjacently disposed in the front projection of the display panel, and the same-color sub-pixels 13a in one row of the sub-pixels 13a are charged simultaneously, so that the plurality of first data leads 131 providing the data signals to the same-color sub-pixels 13a provide the data signals to the corresponding same-color sub-pixels 13a simultaneously, thereby correspondingly reducing the charging coupling effect and crosstalk between the plurality of first data leads 131, and thus improving the vertical streaking phenomenon in the severe picture in the prior art.
It should be noted that, the first data lead 131 corresponding to the sub-pixel column located on the left side of the central symmetry axis of the hollow area 11 may be optionally disposed in the first non-display area 12 located on the left side of the central symmetry axis of the hollow area 11, and the first data lead 131 corresponding to the red sub-pixel R, the first data lead 131 corresponding to the green sub-pixel G, and the first data lead 131 corresponding to the blue sub-pixel B in the first non-display area 12 located on the left side of the central symmetry axis of the hollow area 11 may be disposed adjacently. Similarly, the arrangement of the first data leads 131 corresponding to the sub-pixel rows located on the right side of the central symmetry axis of the hollow area 11 is similar to that on the left side.
Illustratively, on the basis of any of the above embodiments, it may be selected that in the first non-display area 12 shown in fig. 2 or fig. 3, at least two first data wires 131 providing data signals to the same-color sub-pixels 13a are adjacently disposed in the front projection of the display panel, and polarities of data signals transmitted by at least two adjacent first data wires 131 in the at least two first data wires 131 are the same. In this embodiment, at least two first data leads 131 providing data signals to the same-color sub-pixels 13a are adjacently disposed in the orthographic projection of the display panel, and then the at least two adjacently disposed first data leads 131 can provide data signals to the corresponding same-color sub-pixels 13a at the same time, so that the sub-pixel charging coupling effect and crosstalk between the at least two first data leads 131 are correspondingly reduced, and thus the phenomenon of vertical stripes existing in a severe picture in the prior art can be improved. On the other hand, at least two first data leads 131 providing data signals to the same color sub-pixels 13a are adjacently disposed and the polarities of the transmitted data signals are the same, so that the coupling capacitance and crosstalk are reduced when the two adjacent first data leads 131 output the data signals with the same polarity, and the phenomenon of vertical stripes existing in a severe picture in the prior art is further improved.
Illustratively, on the basis of any of the above embodiments, at least a portion of the first data lead 131 and the second data lead 132 may be located at different film layers and arranged in an insulating manner as shown in fig. 4, and at least a portion of the first data lead 131 is electrically connected to the corresponding second data lead 132 through the first via 133, where fig. 5 is a cross-sectional view taken along a-a' in fig. 4. In this embodiment, in order to further implement the full-screen technology, the size of the first non-display area 12 at the periphery of the hollow area 11 is smaller, and based on this, the distance between any two adjacent first data leads 131 is smaller, and a coupling capacitor may exist. In order to reduce the coupling capacitance, if there are portions of the first data lead 131 and the second data lead 132 in the first non-display region 12, which are located in different film layers, and there are portions of the first data lead 131 and the second data lead 132, which are located in the same film layer, then there are portions of the first data lead 131 adjacent to each other in the first non-display region 12, which are located in different film layers, so that the coupling capacitance between the portions of the first data lead 131 adjacent to each other can be reduced, the crosstalk can be further reduced, and the moire phenomenon can be improved.
For example, on the basis of any of the above embodiments, the distance L1 between any two adjacent first data leads 131 in the first non-display area 12 in the winding area shown in fig. 6 may be selected to be smaller than or equal to the distance L2 between any two adjacent second data leads 132 in the display area 13. In this embodiment, in order to further implement the full-screen technology, the size of the first non-display area 12 at the periphery of the hollow area 11 is smaller, and based on this, the distance L1 between any two adjacent first data wires 131 is smaller, so that the size or area of the first non-display area 12 can be reduced. Note that, here, the distance L1 and the distance L2 are both distances in the first direction X.
Alternatively, as shown in fig. 6, in the first non-display area 12, the distance L1 between any two adjacent first data leads 131 providing data signals to the same-color sub-pixels 13a in the winding area is smaller than or equal to the distance L3 between two adjacent first data leads 131 providing data signals to different-color sub-pixels 13a in the first non-display area 12 in the winding area. In this embodiment, any two adjacent first data leads 131 providing data signals to the same color sub-pixels 13a in the first non-display area 12 simultaneously charge the corresponding sub-pixels 13a, so that the coupling effect between the any two adjacent first data leads 131 is reduced, thereby reducing crosstalk and improving the moire phenomenon, and on the basis, a smaller interval L1 can be set between the any two adjacent first data leads 131 to reduce the size of the first non-display area 12, thereby implementing a narrow frame and full screen technology. Two adjacent first data leads 131 in the first non-display region 12 for providing data signals to the sub-pixels 13a of different colors do not charge the corresponding sub-pixels 13a at the same time, so there may be charging coupling effect and crosstalk between the two adjacent first data leads 131, and in order to reduce the charging coupling effect and the crosstalk, the two adjacent first data leads 131 may be arranged at a larger interval L3. Here, the distance L3 is a distance along the first direction X.
Illustratively, on the basis of any of the above embodiments, the second non-display region 14 shown in fig. 7 may be optionally provided with a plurality of data selection circuits 15, the data selection circuits 15 include 1 st to nth data selection switches, an output terminal of one data selection switch 15a is disposed and electrically connected with one data line 13b, n data lines 13b electrically connected with each data selection circuit 15 are used for providing data signals to n columns of different color sub-pixels 13a, and n is greater than or equal to 2 and less than or equal to m.
In this embodiment, the second non-display region 14 is further provided with a driving chip 20. The driving chip 20 includes a plurality of signal output terminals S1 to Sk, each signal output terminal corresponds to at least one data selection circuit 15, for each data selection circuit 15, the input terminals of n data selection switches 15a are electrically connected and electrically connected to the corresponding signal output terminal, and the signal output terminal of the driving chip 20 is used for providing a data signal to each data selection switch 15a of the corresponding at least one data selection circuit 15. The driving chip 20 further includes n control output terminals CKH 1-CKHn, the 1 st data selection switch of each data selection circuit 15 is electrically connected to the 1 st control output terminal CKH1 of the driving chip 20, the 2 nd data selection switch of each data selection circuit 15 is electrically connected to the 2 nd control output terminal CKH2 of the driving chip 20, and so on, the nth data selection switch of each data selection circuit 15 is electrically connected to the nth control output terminal CKHn of the driving chip 20, and the control output terminals of the driving chip 20 are used for controlling the corresponding data selection switches 15a to be turned on or turned off simultaneously. The output terminal of the data selection switch 15a is disposed corresponding to and electrically connected to the data line 13 b. By driving the data lines 13b with the data selection circuit 15, the area of the second non-display region 14 can be reduced, and the full-screen technology can be realized.
It is understood by those skilled in the art that the driver chip 20 disposed above the hollow area 11 as shown in fig. 7 is only a specific example, and in other alternative embodiments, the driver chip may be disposed in a second non-display area below the display panel, which is not limited in the present invention.
Alternatively, as shown in fig. 7, the second non-display area 14 is further provided with 1 st to nth timing signal lines, the ith timing signal line is electrically connected to the ith data selection switch of each data selection circuit 15, and the ith timing signal line is used for controlling the ith data selection switch of each data selection circuit 15 to be turned on or off, so that the data signal received by the data selection circuit 15 is transmitted to the corresponding data line 13b when the ith data selection switch is turned on, i is 1,2, …, n. In this embodiment, the driving chip 20 includes n control output terminals CKH 1-CKHn, which are respectively disposed corresponding to the n timing signal lines one by one, so that each control output terminal CKH is electrically connected to the corresponding timing signal line and controls the corresponding data selection switches 15a to be turned on or turned off at the same time.
