Background
Because Thin Film transistor liquid Crystal displays (TFT-LCDs) have the advantages of low radiation, small size, low energy consumption, etc., they are widely used in various electronic information products. In addition, in order to actively develop a new liquid crystal panel with High transmittance (HLT) and low cost, a Data Line Sharing (DLS) large viewing angle pixel driving scheme as shown in fig. 1 has been proposed by manufacturers. The DLS architecture reduces the cost of the panel by reducing the number of Source Drivers (SD), and adopts a 4-domain pixel design to improve the transmittance of the panel. However, the 4-domain lcd panel has a large viewing angle and a serious color shift problem, and needs to be matched with a large viewing angle lifting algorithm, but when the DLS architecture shown in fig. 1 is matched with a large viewing angle algorithm, the positive and negative polarities in the column direction H are not uniformly distributed, and the brightness of the positive and negative polarities is different, which results in a problem of a wiggle texture (flickerline).

As shown in fig. 2, the present embodiment provides a display panel 1 including a plurality of data lines, a plurality of scan lines, a plurality of pixel units, a source driver and a gate driver. The source driver 2 is connected to the plurality of pixel units through the data lines, and is configured to output the data signals.

In the present embodiment, only the data lines D1-D7, the scan lines S1-S8 and the pixel units 11-14 will be described. As shown in FIG. 2, each of the data lines D1-D7 is arranged vertically. Each of the scan lines S1-S8 is arranged horizontally and intersects each of the data lines D1-D7.
Each pixel unit is arranged between two adjacent data lines and respectively comprises two sub-pixels arranged in an array. The first pixel unit 11, the second pixel unit 12, the third pixel unit 13 and the fourth pixel unit 14 are respectively defined between the first data line D1 and the second data line D2.

That is, one of the source and drain of the Thin Film Transistor (TFT) of each sub-pixel is connected to the second data line D2 or the first data line D1, and the gate of the Thin Film Transistor (TFT) of each sub-pixel is connected to the scan lines S3-S4 and S5-S6, respectively.
Specifically, in the embodiment shown in fig. 2, the first sub-pixels 111 and 141 and the second sub-pixels 112 and 142 in the first pixel unit 11 and the fourth pixel unit 14 are respectively connected to the first data line D1. The first sub-pixels 121 and 131 and the second sub-pixels 122 and 132 in the second pixel unit 12 and the third pixel unit 13 are respectively connected to the second data line D2, and so on, thereby achieving a complete Data Line Sharing (DLS) display panel architecture and a display panel mode, realizing compatibility of the DLS architecture and a large viewing angle algorithm, and promoting mass production of DLS display panels.
However, in other different embodiments, the first sub-pixels 111, 141 and the second sub-pixels 112, 142 in the first pixel unit 11 and the fourth pixel unit 14 may also be respectively connected to the second data line D2. The first sub-pixels 121, 131 and the second sub-pixels 122, 132 in the second pixel unit 12 and the third pixel unit 13 are respectively connected to the first data line D1, and so on, which can also achieve a complete DLS display panel structure and display panel manner.
The connection modes of the first sub-pixel and the second sub-pixel and the data lines in each pixel unit can be combined in any time sequence. In the embodiment shown in fig. 2, the first sub-pixels 111 and 141 in the first pixel unit 11 and the fourth pixel unit 14 are respectively connected to the first data line D1 and the scan lines S1 and S7 of odd rows. The second sub-pixels 112 in the first pixel unit 11 and the fourth pixel unit 14 are respectively connected to the first data line D1 and the scan lines S2 and S8 of even rows.

However, in the embodiment shown in fig. 3, the first sub-pixels 111 and 141 in the first pixel unit 11 and the fourth pixel unit 14 are respectively connected to the first data line D1 and the scan lines S2 and S8 of the even rows. The second sub-pixels 112 and 142 in the first pixel unit 11 and the fourth pixel unit 14 can be respectively connected to the first data line D1 and the scan lines S1 and S7 of odd rows. The first sub-pixels 121 and 131 in the second pixel unit 12 and the third pixel unit 13 are respectively connected to the second data line D2 and the scan lines S4 and S6 of even rows. The second sub-pixels 122, 132 in the second pixel unit 12 and the third pixel unit 13 are respectively connected to the second data line D2 and the scan lines S3, S5 of odd rows.
Therefore, regarding the two sub-pixels 111, 112 in the first pixel unit 11, in the embodiment shown in fig. 2, the first sub-pixel (i.e. the blue sub-pixel) 111 is brighter than the second sub-pixel (i.e. the green sub-pixel) 112 in terms of time sequence. In the embodiment shown in fig. 3, the second sub-pixel (green sub-pixel) 112 may be turned on before the first sub-pixel (blue sub-pixel) 111 in terms of timing, and may be changed as necessary.
In the embodiment shown in FIG. 2 and FIG. 3, the driving polarities of the first pixel unit 11 and the fourth pixel unit 14 along each of the scan lines S1-S8 are sequentially H + L +, H-L-, …. The driving polarities of the second pixel unit 12 and the third pixel unit 13 corresponding to the first pixel unit 11 and the fourth pixel unit 14 are opposite, and are sequentially H-L-, H + L +, and …. Specifically, the driving polarities of all the sub-pixels in each pixel unit are the same, and are opposite to the driving polarities of all the sub-pixels of each pixel unit between adjacent pixels.
In addition, the driving polarities of the first sub-pixels 111, 112, 113, and 114 and the second sub-pixels 112, 122, 132, and 142 in each of the pixel units 11 to 14 are the same, and the driving polarities of the first sub-pixels 111, 112, 113, and 114 and the second sub-pixels 112, 122, 132, and 142 in each of the adjacent pixel units are opposite.
As the driving voltage of the first data line D1 changes, H + L + to H-L-, the switching from H + L + to H-L-exists, so that the distribution of the positive polarity and the negative polarity of H in the column direction is uniform, the brightness of the positive polarity and the negative polarity does not have difference, and the problem of wobbles is solved.
In the embodiment shown in fig. 2, a source driver 2 and a gate driver 3 are further included. The source driver 2 is connected to each of the pixel units through each of the data lines D1-D7, and outputs a data signal. The gate driver 3 is connected to each of the pixel units through each of the scan lines S1-S8, and outputs a scan signal.
Referring to fig. 4, the present invention further provides a display device 5, wherein the display device 5 includes a display panel 1. The Display device 5 includes, but is not limited to, a Liquid Crystal Display (LCD) or an Organic Light Emitting Display (OLED). Other devices and functions of the display device 5 are the same as those of the conventional display panel, and are not described herein again. The structure and the pixel driving method of the display panel 1 are described with reference to the above embodiments.
The display panel 1 of the embodiment can ensure the fineness of the image quality of the display device 5 as much as possible by using a Data Mapping (Data Mapping) mode of matching the large viewing angle algorithm with the driving polarity HLHL, and improve the viewing angles of HG2D (half gate lines (number) and half Data lines (number)) panels under the conditions of weak graininess of the display picture, no wobbling (flickerline) and no signal firm (crostalk) and low power consumption, thereby promoting the mass production of the DLS display panel 1.
