[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0025] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted.

[0026] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0027] Figure 1 The DRD architecture is a commonly used sub-pixel arrangement in long and short hands. G1 is the first row of scan lines, G2 is the second row of scan lines, ..., G4 is the fourth row of scan lines, D1 is the first column of data lines, D2 is the second column of data lines, and D3 is the third column of data lines. The 2G1D architecture can open a complete row of pixels through two rows of scan lines, so that the data lines are halved and the scan lines are doubled. The increased scan lines can be realized by designing a GOA circuit on the side through a scan reduction mechanism, thus saving the cost of the source chip. The inventor of the present application found that because the parasitic capacitance Cgs of the long-connected pixel thin film transistor and the parasitic capacitance Cgs of the short-connected thin film transistor are different, the coupling voltages of adjacent column pixels are different, such as Figure 1 There is a difference between the coupling voltage V1 and the coupling voltage V2, resulting in a brightness difference between two adjacent columns of pixels; when the user shakes his head, he may observe alternating light and dark stripes (i.e., shaking head lines), which affects the display quality.

[0028] In order to solve the above problems, the present application provides a first display panel, which specifically includes the following embodiments:

[0029] First embodiment

[0030] Figure 2 FIG. 1 is a schematic diagram of the structure of a first display panel provided in an embodiment of the present application; Figure 2 As shown, the display panel 100 includes: 2N rows of scan lines 110, M columns of data lines 120 and N rows×M columns of pixel units 130; the nth row of scan lines 110 and the n+1th row of scan lines 110 are arranged below the nth row of pixel units 130; that is, each pixel unit 130 includes a first connection terminal and a second connection terminal; wherein the pixel unit 130 includes a charging transistor and a liquid crystal capacitor, the control terminal of the charging transistor is connected to the scan line 110 as the first connection terminal, and the charging transistor is turned on by receiving a driving signal on the scan line 110 through the first connection terminal; the first terminal of the charging transistor is connected to the data line 120 as the second connection terminal, and the second terminal of the charging transistor is connected to the liquid crystal capacitor, and the data signal on the data line 120 is received through the second connection terminal to charge the liquid crystal capacitor. wherein n, m, N and M are all integers greater than 1, N and M are constants, n and m are variables, the value range of n is from 1 to N, and the value range of m is from 1 to M.

[0031] exist Figure 2 In the embodiment, the scan line 110 and the data line 120 cross but are not connected. Figure 2G1, G2, ..., G8 represent the first row of scan lines 110, the second row of scan lines 110, ..., and the eighth row of scan lines 110, respectively; D1, D2, ..., D12 represent the first column of data lines 120, the second column of data lines 120, ..., and the twelfth column of data lines 120, respectively; F1, F2, ..., F6 represent the first output terminal, the second output terminal, ..., and the sixth output terminal of the source chip (Source IC), respectively. It should be noted that Figure 2 Only 8 rows of scan lines 110, 12 columns of data lines 120 and 6 output ports are shown as examples. Figure 2 The layout architecture uses various resolution combinations for cyclic layout.

[0032] In this embodiment, the pixel polarity of the 2i-1th column pixel unit 130 in the current frame is the first polarity, and the pixel polarity of the 2ith column pixel unit 130 is the second polarity; in the next frame, the pixel polarity of the 2i-1th column pixel unit 130 is the second polarity, and the pixel polarity of the 2ith column pixel unit 130 is the first polarity; it should be noted that the polarities of the first polarity and the second polarity are opposite; that is to say: the first polarity can be positive, and the second polarity is negative; the first polarity can also be negative, and the second polarity is positive. For the convenience of explanation, this application is explained by taking the first polarity as positive and the second polarity as negative as an example; in the current frame, the odd-numbered column pixel unit 130 is positive, and the even-numbered column pixel unit 130 is negative; in the next frame, the odd-numbered column pixel unit 130 is negative, and the even-numbered column pixel unit 130 is negative.

[0033] In this embodiment, the first color, the second color and the third color can be any combination of red, green and blue; this application takes the first color being red, the second color being green and the third color being blue as an example, the pixel color of the 3j-2th column pixel unit 130 is the first color, the pixel color of the 3j-1th column pixel unit 130 is the second color, and the pixel color of the 3jth column pixel unit 130 is the third color, which can be expressed as: the 1st column is red, the 2nd column is green, the 3rd column is blue, the 4th column is red, the 5th column is green, the 6th column is blue, and so on, the M-2th column is red, the M-2th column is green, and the Mth column is blue; wherein j is a variable, and its value range is 1 to It means M is divided by 3 and rounded up.

[0034] In this embodiment, the first connection end of the pixel unit 130 in the mth column is electrically connected to the nth row scan line 110 or the n+1th row scan line 110, and the two data lines 120 corresponding to the two columns of pixel units 130 with the same color and the same polarity are connected to each other, which is specifically expressed as: the first connection ends of the pixel units 130 in the 6x-5th column, 6x-4th ​​column, 6x-3th column, 6x-2th column, 6x-1th column and 6xth column are electrically connected to the nth row scan line 110, and the first connection ends of the pixel units 130 in the 6x+1th column, 6x+1th column, 6x+3th column, 6x+4th column, 6x+5 .... The first connection ends of the pixel units 130 in the n+1th row and the 6x+6th row are electrically connected to the scan line 110 in the n+1th row; further, the data line 120 in the 6x-5th column is connected to the data line 120 in the 6x+1th column, the data line 120 in the 6x-4th ​​column is connected to the data line 120 in the 6x+2th column, the data line 120 in the 6x-3th column is connected to the data line 120 in the 6x+4th column, the data line 120 in the 6x-2th column is connected to the data line 120 in the 6x+6th column, and the data line 120 in the 6xth column is connected to the data line 120 in the 6x+6th column; wherein, It means (M-6) divided by 6 and rounded up.

[0035] like Figure 2 As shown, the data line 120 corresponding to the pixel unit 130 in the first column is the data line 120 in the first column, the data line 120 corresponding to the pixel unit 130 in the second column is the data line 120 in the second column, and so on. The data line 120 corresponding to the pixel unit 130 in the Mth column is the data line 120 in the Mth column. Since the pixel colors and polarities in the first column and the seventh column are the same, the pixel colors and polarities in the second column and the eighth column are the same, ..., the pixel colors and polarities in the sixth column and the twelfth column are the same, the data line 120 in the first column can be After the data line 120 is connected to the data line 120 in the 7th column, it is electrically connected to the first port of the source chip. After the data line 120 in the 2nd column is connected to the data line 120 in the 8th column, it is electrically connected to the second port of the source chip. And so on. After the data lines 120 in the 6th column and the 12th column are connected, they are electrically connected to the sixth port of the source chip. At the same time, the pixel units 130 in the 1st to 6th columns are all connected to the scan line 110 in the nth row, and the pixel units 130 in the 7th to 12th columns are all connected to the scan line 110 in the n+1th row.

[0036] It can be seen that, since the data lines 120 corresponding to the two columns of pixel units 130 with the same pixel color and polarity are connected together, and the two columns of pixel units 130 are respectively connected to different scan lines 110, they can be driven by the same data output port of the source chip; Figure 2As shown, except for the connection between the 6th column and the 7th column, the connection lengths between other two adjacent columns and the data line 120 are the same as the connection lengths between the scan line 110, so there is no difference in coupling voltage between adjacent pixels, that is, there is no brightness difference between most of the pixels in two adjacent columns; it should also be noted that although the lengths of the scanning lines connected to the pixel units in the 6th column and the 7th column are different, compared with the design scheme of long and short hands in the related art, the length difference between the 6th column and the 7th column in this embodiment is smaller, so that the coupling voltage difference is smaller, and the brightness difference between the 6th column and the 7th column is also smaller; that is to say: in this embodiment, there is no difference in coupling voltage between adjacent columns or the difference in coupling voltage is small.

[0037] However, if Figure 2 As shown in the figure: the first 6 columns of each row of pixel units 130 are connected to the relatively close scanning line 110, and the last 6 columns are connected to the relatively far scanning line 110; it is this connection difference that causes the pixel brightness of the first 6 columns and the last columns to be inconsistent, that is, there will be a brightness difference between the pixel units 130 of the adjacent 6 columns; but the width of the 6 columns of pixel units 130 (about 0.5mm) is just in the sensitive resolution range of the human eye, which is vertical light and dark lines from a macroscopic point of view; therefore, although the first embodiment solves the problem of head shaking lines, there will be the problem of vertical light and dark lines that can be distinguished by the human eye; in order to solve this problem, the present application provides a second display panel 100, which specifically includes the following embodiments:

[0038] Second embodiment

[0039] Figure 3 FIG. 2 is a schematic diagram of the structure of a second display panel provided in an embodiment of the present application; Figure 3 As shown, the second embodiment is identical to the first embodiment in the number and arrangement of the scan lines 110, the data lines 120 and the pixel units 130, as well as the arrangement of the pixel polarities, which will not be described in detail here; the difference between the second embodiment and the first embodiment lies in the different distribution of pixel colors, the connection relationship between the data lines 120, and the connection relationship between the pixel units 130 and the scan lines 110.

[0040] like Figure 3As shown, the pixel color distribution of the second embodiment is as follows: the pixel color of the pixel unit 130 in the 12j-11th column is the first color, the pixel color of the pixel unit 130 in the 12j-10th column is the second color, the pixel color of the pixel unit 130 in the 12j-9th column is the first color, the pixel color of the pixel unit 130 in the 12j-8th column is the second color, the pixel color of the pixel unit 130 in the 12j-7th column is the third color, and the pixel color of the pixel unit 130 in the 12j-6th column is the third color. The pixel color of the pixel unit 130 in the 12j-5th column is the first color, the pixel color of the pixel unit 130 in the 12j-4th column is the first color, the pixel color of the pixel unit 130 in the 12j-3th column is the second color, the pixel color of the pixel unit 130 in the 12j-2th column is the third color, the pixel color of the pixel unit 130 in the 12j-1th column is the second color, and the pixel color of the pixel unit 130 in the 12jth column is the third color; wherein j is a variable, and its value range is It means M divided by 12 and rounded up.

[0041] It should be noted that the first color, the second color and the third color can be any combination of red, green and blue; this embodiment takes the first color being red, the second color being green and the third color being blue as an example. In this embodiment, the 1st column is red, the 2nd column is green, the 3rd column is red, the 4th column is green, the 5th column is blue, the 6th column is red, the 7th column is blue, the 8th column is red, the 9th column is green, the 10th column is blue, the 11th column is green, the 12th column is blue, and so on, and the colors from the 1st column to the 12th column are distributed as one group and cycled in sequence.

[0042] In this embodiment, the first connection end of the pixel unit 130 in the mth column is electrically connected to the scan line 110 in the nth row or the scan line 110 in the n+1th row, and the two data lines 120 corresponding to the two columns of pixel units 130 with the same color and the same polarity are connected to each other, which is specifically expressed as follows: the first connection ends of the pixel units 130 in the 2x-1th column and the 2xth column are electrically connected to the scan line 110 in the nth row, and the first connection ends of the pixel units 130 in the 2x+1th column and the 2x+2th column are electrically connected to the scan line 110 in the n+1th row; the data line 120 in the 2x-1th column is connected to the data line 120 in the 2x+1th column, and the data line 120 in the 2xth column is connected to the data line 120 in the 2x+2th column.

[0043] like Figure 3As shown, the data line 120 corresponding to the pixel unit 130 in the first column is the data line 120 in the first column, the data line 120 corresponding to the pixel unit 130 in the second column is the data line 120 in the second column, and so on, the data line 120 corresponding to the pixel unit 130 in the Mth column is the data line 120 in the Mth column; and because the pixel colors and polarities in the first column and the third column are the same, the pixel colors and polarities in the second column and the fourth column are the same, the pixel colors and polarities in the fifth column and the seventh column are the same, the pixel colors and polarities in the sixth column and the eighth column are the same, the pixel colors and polarities in the ninth column and the eleventh column are the same, and the pixel colors and polarities in the tenth column and the twelfth column are the same; therefore, the data line 120 in the first column and the data line 120 in the third column can be connected and then electrically connected to the first port of the source chip, and the data line 120 in the second column can be connected to the data line 120 in the fourth column. After the data line 120 in the 5th column is connected, it is electrically connected to the second port of the source chip. After the data line 120 in the 7th column is connected, it is electrically connected to the third port of the source chip. After the data line 120 in the 6th column is connected to the data line 120 in the 8th column, it is electrically connected to the fourth port of the source chip. After the data line 120 in the 9th column is connected to the data line 120 in the 11th column, it is electrically connected to the fifth port of the source chip. After the data line 120 in the 10th column is connected to the data line 120 in the 12th column, it is electrically connected to the sixth port of the source chip. At the same time, the pixel units 130 in the 1st column, the 2nd column, the 5th column, the 6th column, the 9th column, and the 10th column are all connected to the scan line 110 in the nth row, and the pixel units 130 in the 3rd column, the 4th column, the 7th column, the 8th column, the 11th column, and the 12th column are all connected to the scan line 110 in the n+1th row.

[0044] It can be seen that, since the data lines 120 corresponding to the two columns of pixel units 130 with the same pixel color and polarity are connected together, and the two columns of pixel units 130 are respectively connected to different scan lines 110, they can be driven by the same data output port of the source chip; Figure 3 As shown, the connection length between two adjacent columns and the data line 120 is small, so there is no difference in coupling voltage between adjacent columns, that is, there is no brightness difference between most of the pixels in two adjacent columns, thereby solving the problem of shaking head lines. In addition, the first two columns of each row of pixel units 130 are connected to the relatively close scanning line 110, and the last two columns are connected to the relatively far scanning line 110, and they are arranged alternately, with two adjacent columns of pixel units 130 as a column of pixel groups, resulting in inconsistent pixel brightness of two adjacent columns of pixel groups, that is, there will be brightness differences between two adjacent columns of pixel groups; compared with the first embodiment, the pixel difference width is reduced by one third (about 0.16mm), which is not within the resolution range of the human eye, and the human eye cannot see the vertical light and dark lines from a macroscopic point of view; therefore, the second embodiment not only solves the problem of shaking head lines, but also solves the problem of vertical light and dark lines that can be seen by the human eye in the first embodiment, further improving the display effect of the panel.

[0045] It should also be noted that, although the lengths of the scan lines connecting the second and third columns of pixel units are different, compared with the long-short hand design in the related art, the length difference between the second and third columns in this embodiment is smaller, so that the coupling voltage difference is smaller, and the brightness difference between the second and third columns is also smaller; that is to say: although there is still a brightness difference between the two connected pixel groups, the brightness difference is weaker than that in the prior art, and the width of the difference is unrecognizable to the human eye, so while solving the head shake lines, the problem of vertical light and dark lines is also solved.

[0046] In order to solve the problem of vertical light and dark stripes visible to human eyes in the first embodiment, the present application also provides a third display panel 100, which specifically includes the following embodiments:

[0047] Third embodiment

[0048] Figure 4 FIG. 4 is a schematic diagram showing the structure of a third display panel provided in an embodiment of the present application; Figure 4 As shown, the third embodiment is identical to the first embodiment in the number and arrangement of the scan lines 110, the data lines 120 and the pixel units 130, as well as the arrangement of the pixel colors, which will not be described in detail here; the difference between the third embodiment and the first embodiment lies in the distribution of pixel polarities, the connection relationship between the data lines 120, and the connection relationship between the pixel units 130 and the scan lines 110.

[0049] like Figure 4 As shown, the pixel color distribution of the third embodiment is: the pixel color of the pixel unit 130 in the 3i-2 column is the first color, the pixel color of the pixel unit 130 in the 3i-1 column is the second color, and the pixel color of the pixel unit 130 in the 3i column is the third color; that is, each row is arranged in a cyclic manner of red, green and blue.

[0050] like Figure 4 As shown, the pixel polarity distribution mode of the third embodiment is: in the current image frame, the pixel polarity of the pixel unit 130 in the 3i-2th column is the first polarity, the pixel polarity of the pixel unit 130 in the 3i-1th column is the second polarity, and the pixel polarity of the pixel unit 130 in the 3i-th column is the second polarity; in the next frame, the pixel polarity of the pixel unit 130 in the 3i-2th column is the second polarity, the pixel polarity of the pixel unit 130 in the 3i-1th column is the first polarity, and the pixel polarity of the pixel unit 130 in the 3i-th column is the first polarity; wherein, That is to say, in the current frame, the polarity of pixels in each row is cycled in a positive, negative and negative arrangement.

[0051] In this embodiment, the first connection end of the pixel unit 130 in the mth column is electrically connected to the scan line 110 in the nth row or the scan line 110 in the n+1th row, and the two data lines 120 corresponding to the two columns of pixel units 130 with the same color and the same polarity are connected to each other, which is specifically expressed as follows: the first connection ends of the pixel units 130 in the 3x-2th column, the 3x-1th column, and the 3xth column are electrically connected to the scan line 110 in the nth row, and the first connection ends of the pixel units 130 in the 3x+1th column, the 3x+2th column, and the 3x+3th column are electrically connected to the scan line 110 in the n+1th row; the data line 120 in the 3x-2th column is connected to the data line 120 in the 3x+1th column, the data line 120 in the 3x-1th column is connected to the data line 120 in the 3x+2th column, and the data line 120 in the 3xth column is connected to the data line 120 in the 3x+3th column; wherein,

[0052] like Figure 4 As shown, the data line 120 corresponding to the pixel unit 130 in the first column is the data line 120 in the first column, the data line 120 corresponding to the pixel unit 130 in the second column is the data line 120 in the second column, and so on, the data line 120 corresponding to the pixel unit 130 in the Mth column is the data line 120 in the Mth column; and because the pixel colors and polarities in the first column and the fourth column are the same, the pixel colors and polarities in the second column and the fifth column are the same, the pixel colors and polarities in the third column and the sixth column are the same, the pixel colors and polarities in the seventh column and the tenth column are the same, the pixel colors and polarities in the eighth column and the eleventh column are the same, and the pixel colors and polarities in the ninth column and the twelfth column are the same; therefore, the data line 120 in the first column and the data line 120 in the fourth column can be connected and then electrically connected to the first port of the source chip, and the data line 120 in the second column and the data line 120 in the fifth column can be electrically connected to the first port of the source chip. After the data lines 120 in the first column are connected, they are electrically connected to the second port of the source chip; after the data lines 120 in the third column and the data lines 120 in the sixth column are connected, they are electrically connected to the third port of the source chip; after the data lines 120 in the seventh column and the data lines 120 in the tenth column are connected, they are electrically connected to the fourth port of the source chip; after the data lines 120 in the eighth column and the data lines 120 in the eleventh column are connected, they are electrically connected to the fifth port of the source chip; after the data lines 120 in the ninth column and the data lines 120 in the twelfth column are connected, they are electrically connected to the sixth port of the source chip; at the same time, the pixel units 130 in the first column, the second column, the third column, the seventh column, the eighth column, and the ninth column are all connected to the nth row of scan line 110, and the pixel units 130 in the fourth column, the fifth column, the sixth column, the tenth column, the eleventh column, and the twelfth column are all connected to the n+1th row of scan line 110.

[0053] It can be seen that, since the data lines 120 corresponding to the two columns of pixel units 130 with the same pixel color and polarity are connected together, and the two columns of pixel units 130 are respectively connected to different scan lines 110, they can be driven by the same data output port of the source chip; Figure 4As shown, the connection lengths between two adjacent columns and the data line 120 are the same, so there is no difference in coupling voltage between adjacent columns, that is, there is no brightness difference between most of the pixels in two adjacent columns, thereby solving the problem of shaking head lines. In addition, the first three columns of each row of pixel units 130 are connected to the relatively close scanning line 110, and the last three columns are connected to the relatively far scanning line 110, and are arranged alternately, with three columns of pixel units 130 as a column of pixel groups, resulting in inconsistent pixel brightness between adjacent column pixel groups, that is, there will be brightness differences between two adjacent column pixel groups; compared with the first embodiment, the pixel difference width is reduced by one-half (about 0.25mm), which is not within the resolution range of the human eye, and the human eye cannot see the vertical light and dark lines from a macroscopic perspective; therefore, the third embodiment not only solves the problem of shaking head lines, but also solves the problem of vertical light and dark lines that can be seen by the human eye in the first embodiment, further improving the display effect of the panel.

[0054] In summary, the display panel provided by the present application has at least the following beneficial effects:

[0055] 1. The present application connects each row of pixel units to one column of data lines and to any scan line arranged therebelow, and interconnects two data lines corresponding to two columns of pixel units with the same color and polarity, so that the connection lengths between each column of pixel units and the data lines are the same. Therefore, there is no difference in coupling voltages between adjacent columns or the difference in coupling voltages is small, that is, there is no brightness difference or the brightness difference is small between pixels in adjacent columns, thereby solving the problem of head shake wrinkles.

[0056] 2. This application optimizes the pixel arrangement and polarity inversion method, and while solving the head shake wrinkles, it also reduces the width of the vertical light and dark lines, making the light and dark lines invisible to the human eye, further improving the display effect of the display panel.
