Description

Display panel

Technical Field

The application relates to the technical field of display, in particular to a display panel.

Background

At present, as the demand for large size, high resolution and high refresh rate of display panels is becoming more and more extensive, the problem of insufficient charging of display panels is becoming more and more prominent, and thus, the driving method of display panels is continuously required to be improved.

Fig. 1 is a schematic structural diagram of a HG2D driving architecture in the prior art, as shown in fig. 1, in the HG2D driving architecture, every two rows of Gate lines (Gate lines) are simultaneously turned on, and every one column of sub-pixels is charged by two data lines, the two data lines respectively correspond to pixels in different rows, so that all pixels on the two Gate lines can be simultaneously charged, so that the charging time per sub-pixel row is increased to 2 times, which is equivalent to halving the number of Gate lines and increasing the number of data lines to 2 times, and therefore referred to as HG2D driving architecture, compared to the common 1G1D driving architecture (each row of Gate lines is turned on and each column of sub-pixels is charged by one data line), the HG2D driving architecture increases the charging rate of pixels to 2 times. However, the HG2D driving architecture may still not be suitable for display panels with larger size, higher resolution and higher refresh rate, so the 1/3G3D driving architecture is currently adopted to further improve the charging rate of the display panel.

Fig. 2 is a schematic structural diagram of 1/3G3D driving architecture of the prior art, as shown in fig. 2, in 1/3G3D driving architecture, every three rows of Gate lines (Gate lines) are turned on simultaneously, and every column of sub-pixels are charged by three data lines, and the three data lines correspond to different rows of pixels, respectively, so that all pixels on the three Gate lines can be charged simultaneously, so that the charging time per sub-pixel row is increased to 3 times, the data corresponding to the Gate lines is decreased to 1/3, and the number of data lines is increased to 3 times, so that the driving architecture is called 1/3G3D driving architecture, and compared with the commonly used 1G1D driving architecture (each row of Gate lines is turned on, and each column of sub-pixels is charged by one data line), the charging rate of the pixels is increased to 3 times. However, since the data lines are in the same layer, cross-line interference exists when the data lines in the second column and the data lines in the third column between two adjacent columns of pixels of the 1/3G3D driving scheme corresponding to the same sub-pixel column are connected to the sub-pixels in the column, for example, the connecting line between D3 and the sub-pixel in the third column crosses D2 to generate cross-line interference, and the connecting line between D6 and the sub-pixel in the third column crosses D5 to generate cross-line interference, so that an interference signal is likely to occur when the display panel is driven to display, and therefore, the 1/3G3D driving scheme cannot be used in practice according to the principle that the same layer of metal cannot cross-line. Or the data lines generating cross interference and other data lines need to be arranged in different layers, so that the manufacturing of the display panel is complicated.

Therefore, there is a need to provide a display panel capable of charging pixels faster and without cross-line interference, so as to solve the technical problem of insufficient charging of the display panel with large size, high resolution and high refresh rate.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application.

For convenience of description, the embodiments of the present application are described with respect to a common arrangement direction of scan lines and data lines of a display panel, that is, a first direction X refers to a horizontal direction, and a second direction Y refers to a vertical direction; the rows of sub-pixels are along a first direction X and the columns of sub-pixels are along a second direction Y.

Aiming at the problem that cross-line interference exists when two data lines corresponding to the same sub-pixel column in three data lines between two adjacent columns of sub-pixels in the conventional 1/3G3D driving architecture shown in fig. 2 are respectively connected with the column of sub-pixels, the display panel provided by the embodiment of the application changes one data line in the three data lines corresponding to the same sub-pixel column from vertical arrangement to horizontal arrangement, on the basis, in order to normally drive, one gate line of three gate lines respectively corresponding to every three rows of sub-pixels is changed from horizontal arrangement to vertical arrangement, so that when every two rows and every one column of sub-pixels are simultaneously started, the two rows of sub-pixels in the two rows and one column of sub-pixels are all lighted up by being charged by the vertical data lines, the sub-pixels of the row of sub-pixels corresponding to the vertical scanning line are charged by the horizontal data line and are partially lighted, so that all the pixels are charged and lighted in the sequence in the display time of one frame.

Specifically, an embodiment of the present application provides a display panel, including:

the pixel array is composed of a plurality of sub-pixels distributed in an array, the sub-pixels are divided into a plurality of sub-pixel row groups and a plurality of sub-pixel columns, and each sub-pixel row group comprises a first sub-pixel row, a second sub-pixel row and a third sub-pixel row; it should be noted that each sub-pixel connects one scan line and one data line.

The scanning line groups each comprise a first scanning line, a second scanning line and a third scanning line, wherein the first scanning line and the second scanning line are arranged in parallel along a first direction, the first scanning line is connected with the sub-pixels in the first sub-pixel row, and the second scanning line is connected with the sub-pixels in the second sub-pixel row; the third scanning line is arranged along a second direction perpendicular to the first direction and is connected with the sub-pixels in the sub-pixel column and positioned in the third sub-pixel row;

the pixel array comprises a plurality of data line groups, a plurality of pixel array units and a plurality of pixel array units, wherein each data line group comprises a first data line, a second data line and a third data line, the first data line and the second data line are arranged along a second direction, the first data line is connected with the sub-pixels positioned in a first sub-pixel row in the corresponding sub-pixel column, and the second data line is connected with the sub-pixels positioned in a second sub-pixel row in the corresponding sub-pixel column; the third data line is arranged along the first direction and is connected with the sub-pixels in the third sub-pixel row.

That is, the display panel provided in the embodiment of the present application exchanges 1 scan line and 1 data line of every 3 scan lines and every 3 data lines of the existing 1/3G3D driving architecture shown in fig. 2, so that 3 horizontal scan lines and 3 vertical data lines are changed into 2 horizontal scan lines and 1 vertical horizontal line, and 2 vertical data lines and 1 horizontal data line, thereby reducing the number of 3 data lines disposed between two adjacent columns of sub-pixels to 2 data lines, and the 2 data lines between two adjacent columns of sub-pixels respectively correspond to the two adjacent columns of sub-pixels, thereby avoiding the problem of cross-line interference when the multiple data lines are connected with the corresponding sub-pixels.

It should be understood that, in this embodiment, in the 1/3G3D driving framework, one of 1 scan line and 1 data line is selected and interchanged, the scan line may be any one of every 3 scan lines, and the data line may be any one of every 3 data lines, that is, only the first scan line, the second scan line, and the third scan line respectively corresponding to the sub-pixels in 1 column and 2 rows are required to output scan signals at the same time, the sub-pixels in 2 rows are all lighted by the first data line, the second data line, and the third data line respectively corresponding to the sub-pixels in 1 column and 2 rows, and the sub-pixels in 1 column are partially lighted, and all pixels are lighted in this order within one frame display time, so as to display one frame.

According to the prior art, the first data line and the second data line corresponding to each sub-pixel column are located on two sides of each sub-pixel column, that is, the first data line and the second data line corresponding to the same sub-pixel column are not located on the same side of the sub-pixel column, so that the problem of line crossing interference when the first data line and the second data line of each group of data line groups are connected with the same sub-pixel column is solved. In addition, between two adjacent columns of sub-pixel columns, the first data line or the second data line corresponding to the previous sub-pixel column and the first data line or the second data line corresponding to the next sub-pixel column cannot be interchanged, that is, the first data line or the second data line corresponding to the next sub-pixel column cannot be close to the previous sub-pixel column, and the first data line or the second data line corresponding to the previous sub-pixel column cannot be close to the next sub-pixel column, otherwise, the first data line or the second data line corresponding to the previous sub-pixel column and the first data line or the second data line corresponding to the next sub-pixel column may be crossed.

Based on this, in the present embodiment, the third scanning line between any two adjacent sub-pixel columns is located between two first data lines or two second data lines or between the first data line and the second data line between any two adjacent sub-pixel columns, for example, taking the case that the third scanning line is located between the first data line and the second data line, the third scanning line is located between the first data line connected to the corresponding sub-pixel column and the second data line connected to the sub-pixel column adjacent to the corresponding sub-pixel column, or the third scanning line is located between the second data line connected to the corresponding sub-pixel column and the first data line connected to the sub-pixel column adjacent to the corresponding sub-pixel column.

It should be noted that, in each scan line group, the first scan line, the second scan line, and the third scan line output scan signals at the same time, so the first scan line, the second scan line, and the third scan line of each scan line group may be connected together so as to output signals through the first scan line, the second scan line, and the third scan line at the same time.

Fig. 3 is a schematic structural diagram of a display panel provided in the embodiment of the present application, and as shown in fig. 3, the pixel array is formed by 3m rows and n columns of sub-pixels in an array distribution, where m and n are positive integers.

The 3i-2 th row of sub-pixels are all connected with the same first scanning line G1i, the 3i-1 th row of sub-pixels are all connected with the same second scanning line G2i, and each sub-pixel in the 3i th row of sub-pixels is respectively connected with different third scanning lines G3 k; i is all positive integers from 1 to m. It can be understood that the sub-pixels in the 3i-2 th row, the sub-pixels in the 3i-1 th row and the sub-pixels in the 3i th row can be a first sub-pixel row, a second sub-pixel row and a third sub-pixel row of a certain scanning line group.

The 3i-2 th row of sub-pixels of the same sub-pixel column are connected with the same first data line D1k, the 3i-1 th row of sub-pixels of the same sub-pixel column are connected with the same second data line D2k, and each sub-pixel in the 3i th row of sub-pixels is connected with the same third data line D3 i; k is all positive integers from 1 to n; and the first data line and the second data line corresponding to the same sub-pixel column are positioned at two sides of the same sub-pixel column.

Specifically, for a pixel array composed of 3m rows and n columns of sub-pixels, the scan lines are divided into first scan lines G11, G12 … … G1m and second scan lines G21, G22 … … G2m arranged in parallel in the first direction X and third scan lines G31, G32 … … G3n arranged in the second direction Y, the data lines are divided into first data lines D11, D12 … … D1n and second data lines D21, D22 … … D2n arranged in the second direction Y and third data lines D31, D32 … … D3m arranged in the first direction X.

Further, for a scan line:

i =1, that is, the sub-pixels in the 1 st row are all connected to the first scanning line G11, the sub-pixels in the 2 nd row are all connected to the second data line D21, and each sub-pixel in the 3 rd row is connected to the third scanning line G31, G32 … … G3n, respectively.

i =2, that is, the sub-pixels in the 4 th row are all connected to the first scan line G12, the sub-pixels in the 5 th row are all connected to the second scan line G22, and each sub-pixel in the 6 th row is connected to the third scan line G31, G32 … … G3n, respectively.

By analogy, i = m, that is, the sub-pixels in the 3m-2 th row are all connected to the first scanning line G1m, the sub-pixels in the 3m-1 th row are all connected to the second scanning line G2m, and each sub-pixel in the 3m th row is connected to the third scanning line G31, G32 … … G3n, respectively.

Further, for a data line:

k =1, that is, the sub-pixels of the 1 st row, the 4 th row and the 7 th row … …, the 3m-2 th row in the 1 st column sub-pixel are all connected to the first data line D11, the sub-pixels of the 2 nd row, the 5 th row and the 8 th row … …, the 3m-1 th row in the 1 st column sub-pixel are all connected to the second data line D21, and each sub-pixel in the 3 rd row sub-pixel is connected to the third data line D31.

k =2, i.e. row 1, row 4, row 7 … …, row 3m-2 sub-pixels of the column 2 sub-pixels are all connected to the first data line D12, row 2, row 5, row 8 … …, row 3m-1 sub-pixels of the column 2 sub-pixels are all connected to the second data line D22, and each sub-pixel of the row 3 sub-pixels is connected to the third data line D32.

By analogy, k = n, that is, the sub-pixels of the 1 st, 4 th and 7 th rows … … and 3m-2 th rows in the sub-pixel of the nth column are all connected to the first data line D1n, the sub-pixels of the 2 nd, 5 th and 8 th rows … … and 3m-1 th rows in the sub-pixel of the nth column are all connected to the second data line D2n, and each sub-pixel of the 3 rd row is connected to the third data line D3 m.

In some embodiments, the first scanning line G1i corresponding to the 3i-2 th row of sub-pixels is disposed between the 3i-2 nd row of sub-pixels and the 3i-2 nd row of sub-pixels; the second scanning line G2i corresponding to the sub-pixel in the 3i-1 th row is arranged between the sub-pixel in the 3i-1 th row and the sub-pixel in the 3i th row; the third scanning line G3k corresponding to each sub-pixel in the 3 i-th row is respectively disposed between the sub-pixel column where each sub-pixel is located and the sub-pixel column adjacent to the sub-pixel column where each sub-pixel is located.

For example, the first scanning line G11 corresponding to the sub-pixel in the 1 st row is disposed between the sub-pixels in the 1 st row and the sub-pixels in the 2 nd row, the second scanning line G21 corresponding to the sub-pixel in the 2 nd row is disposed between the sub-pixels in the 2 nd row and the sub-pixels in the 3 rd row, and the third scanning lines G31, G32 … … G3n corresponding to each sub-pixel in the sub-pixels in the 3 rd row.

In some embodiments, the first data line D1k corresponding to the sub-pixel in the 3i-2 th row of the sub-pixels in each column is disposed between the sub-pixel column in which the sub-pixel in the 3i-2 th row of the sub-pixels in the column is located and the sub-pixel column adjacent to the sub-pixel column in which the sub-pixel in the 3i-2 th row of the sub-pixels in the column is located; the second data line D2k corresponding to the sub-pixel in the 3i-1 th row of each column of sub-pixels is arranged between the sub-pixel column where the sub-pixel in the 3i-1 th row of the column of sub-pixels is located and the sub-pixel column adjacent to the sub-pixel column where the sub-pixel in the 3i-1 th row of the column of sub-pixels is located; the third data line D3i corresponding to the sub-pixel in the 3 i-th row is disposed between the sub-pixel row in which the sub-pixel in the 3 i-th row is located and the sub-pixel row adjacent to the sub-pixel row in which the sub-pixel in the 3 i-th row is located.

For example, if the first data line D11 corresponding to the sub-pixel in row 1 of the sub-pixel in column 1 is disposed on the left side of the sub-pixel in column 1, the second data line D21 corresponding to the sub-pixel in row 2 of the sub-pixel in column 1 is disposed on the right side of the sub-pixel in column 1, and the third data line D31 corresponding to the sub-pixel in row 3 is disposed between the 2 nd row and the 3 rd row or between the 3 rd row and the 4 th row.

In order to avoid crosstalk between the second scan line G2i and the third data line D3i, preferably, the second scan line G2i and the third data line D3i are not disposed side by side between two same rows of sub-pixels, for example, the third data line D31 corresponding to the sub-pixel in the 3 rd row is disposed between the 3 rd row and the 4 th row.

It should be noted that the number of rows and columns of the sub-pixels of the pixel array may be two cases:

1. if the number of rows of the sub-pixels is equal to 3 times the number of columns of the sub-pixels, i.e., 3m = n, it can be satisfied that all horizontal scan lines (first scan lines and second scan lines) are grouped with all vertical scan lines (third scan lines), and then each group of the first scan lines, the second scan lines, and the third scan lines can output scan signals at the same time.

2. If the number of rows of the sub-pixels is not 3 times of the number of columns of the sub-pixels, namely 3m ≠ n, if a part of vertical scanning lines (third scanning lines) lack corresponding horizontal scanning lines (first scanning lines and second scanning lines), directly leading out one horizontal scanning line from the part of vertical scanning lines (third scanning lines) for inputting scanning signals, and leading out the horizontal scanning line only for leading in the scanning signals for the part of vertical scanning lines (third scanning lines) without corresponding to any sub-pixels; alternatively, if some horizontal scanning lines (generally, the first scanning lines) lack a group of horizontal scanning lines (generally, the second scanning lines) and only a group of vertical scanning lines (generally, the third scanning lines) is present, the some horizontal scanning lines (the first scanning lines) are connected to only the group of third scanning lines.

Note that, in order to avoid crosstalk generated due to cross between the third data line D3i arranged in the first direction X and the first data line D1k or the second data line D2k arranged in the second direction Y, the embodiment of the present application arranges the third data line D3i arranged in the first direction X on the first metal layer M1 (gate layer) where the first scan line G1i and the second scan line G2i are located, that is: the first scan line G1i, the second scan line G2i, the third data line D3i and the gate of the tft of the sub-pixel are all disposed on the first metal layer M1 (not shown in the drawings). Similarly, in order to avoid crosstalk generated between the third scan line G3k disposed along the second direction Y and the first scan line G1i or the second scan line G2i disposed along the first direction X due to intersection, in the embodiment of the present application, the third scan line disposed in a handling manner is disposed on the second metal layer M2 (source drain layer) of the first data line D1k and the second data line D2k, that is: the first data line D1k, the second data line D2k, and the third scan line G3k, and the source and drain of the thin film transistor of the sub-pixel are disposed on the second metal layer M2 (not shown in the drawings).

An insulating layer (not shown) is disposed between the first metal layer M1 and the second metal layer M2, a first via hole and a second via hole (not shown) are disposed in the insulating layer, and a first via hole and a second via hole are disposed in the insulating layer. The third scanning line G3k is connected to the sub-pixels in the third sub-pixel row in the sub-pixel column through the first via, and the third data line D3i is connected to the sub-pixels in the third sub-pixel row through the second via. That is, in fig. 3, the third scan line G3k in the second metal layer M2 is connected to the corresponding sub-pixel through the connection line led out of the first metal layer M1 through the first via hole, so that the third scan line G3k is connected to the corresponding sub-pixel without crossing the first data line D1k or the second data line D2k, thereby causing crosstalk. Similarly, the third data line D3i in the first metal layer M1 is connected to the corresponding sub-pixel through the connection line led out of the second metal layer M2 by the first and second via holes, so if the third data line D3i and the second scan line D2k are in the same two rows of adjacent sub-pixels, the third data line D3i is connected to the corresponding sub-pixel without crossing the second scan line D2k, which may cause crosstalk.

In some embodiments, the polarities of the consecutive first data lines D1k and the consecutive second data lines D2k are opposite, and the polarities of the consecutive two third data lines D3i are opposite, so as to implement a row inversion driving manner.

In some embodiments, each sub-pixel of the pixel array shown in fig. 3 represents a red sub-pixel, a green sub-pixel, a blue sub-pixel, or other color sub-pixels, respectively, and the same sub-pixel column is the same color sub-pixel, or the same sub-pixel row is the same color sub-pixel.

If each pixel point is composed of a red sub-pixel, a green sub-pixel and a blue sub-pixel, it can be understood that, if the same sub-pixel column is the sub-pixel of the same color, the number of sub-pixel columns of the pixel array is a multiple of 3, and the number of sub-pixel rows may be a multiple of 3, or may not be a multiple of 3. Similarly, if the same sub-pixel row is a sub-pixel of the same color, the number of sub-pixel rows of the pixel array is a multiple of 3, and the number of sub-pixel columns may be a multiple of 3 or not.

Fig. 4 is a schematic specific flowchart of a driving method of a display panel provided in an embodiment of the present application, and as shown in fig. 4, the embodiment of the present application further provides a driving method of a display panel, which is applied to the display panel, where the driving method includes:

s1, the first scan line, the second scan line and the third scan line of each scan line group simultaneously output scan signals.

First, each group of the first scan line, the second scan line, and the third scan line simultaneously sends out scan signals to scan two rows and one column of sub-pixels, where the first scan line and the second scan line respectively scan two rows of sub-pixels, and the third scan line scans sub-pixels in one sub-pixel column that are not connected to the first scan line and the second scan line (i.e., the third scan line only scans sub-pixels in one sub-pixel column that are not scanned by the first scan line and the second scan line).

S2, the first data line corresponding to the first scan line charges the sub-pixel row scanned by the first scan line, the second data line corresponding to the second scan line charges the sub-pixel row scanned by the second scan line, and the third data line corresponding to the third scan line charges the sub-pixel column scanned by the third scan line.
