This application claims priority to Chinese Patent Application No. 201811076330.3, filed with the Chinese Patent Office on Sep. 14, 2018 and entitled “PIXEL ARRANGEMENT AND DISPLAY PANEL”, which is incorporated herein by reference in its entirety.
This application relates to the field of display technologies, and more particularly to a pixel arrangement and a display panel.
In a color liquid crystal display screen, one display unit (or referred to as a pixel) generally includes three sub-pixels: red (R), green (G), and blue (B). To improve the penetration rate of the liquid crystal display screen, an original structure including three sub-pixels may be changed into a structure including four sub-pixels: R, G, B, and W (white). An arrangement structure of the sub-pixels R, G, B, and W is generally sequential arrangement in a transverse direction (a direction of a scanning line), and each row of pixels has a same arrangement manner. Polarities of drive signals on a data line are +, −, +, −, +, −, . . . . A drive signal Data n on a data line is equal to Data (n+4), that is, a data signal on the 1st data line is consistent with a data signal on the 5th data line. When a same polarity is lit up, only R and B are lit up, and a flicker image is generated. When a pure-color image is lit up, lit-up sub-pixels have a same polarity. Therefore, a voltage of a common electrode is easily pulled up or pulled down, affecting the pixel and resulting in a phenomenon such as flicker, color cast, or cross-talk. For example, when an R pure-color image is lit up, polarities of R sub-pixels are all positive. Consequently, the voltage of the common electrode is easily pulled up, causing sever cross-talk and flicker. When a G pure-color image is lit up, polarities of G sub-pixels are all negative. Consequently, the voltage of the common electrode is easily pulled down, also affecting the whole pixel and causing poor display effects.
An objective of this application is to provide a pixel arrangement, to achieve objectives of, including but not limited to, inhibiting phenomena of flicker, color cast, and cross-talk, and improving display effects.
A technical solution used in an embodiment of this application is: a pixel arrangement, including:

Referring to
Sub-pixel layout of the pixel arrangement is designed in the foregoing manner, and the sub-pixels 10 connected to the eight sequential data lines 30 are used as the repletion unit. The data signal on the Nth data line 30 is the same as the data signal on the (N+8)th data line 30. In one repetition group, the polarities of the data signals of the sub-pixels 10 having the same color that are connected to the same scanning line 20 are opposite, so that when sub-pixels 10 corresponding to a same polarity are lit up, the red sub-pixel 101, the green sub-pixel 102, the blue sub-pixel 103, and the white sub-pixel 104 can be lit up together. When sub-pixels 10 with a same color are lit up, a positive polarity and a negative polarity can coexist. In addition, a drive manner does not need to be improved or complexly designed, to effectively inhibit or avoid phenomena such as flicker, color cast, and cross-talk, and improve display effects.
Optionally, on a same scanning line 20, polarities of data signals of any neighboring sub-pixels may be different, to avoid a VCross-talk phenomenon.
Several specific embodiments are provided below.
Referring to
In addition, sub-pixels 10 corresponding to each scanning line 20 have a same arrangement structure, and the sub-pixels 10 corresponding to the same data line 30 have a same color. That is, each row of sub-pixels 10 has a same color arrangement manner. As shown in
It may be determined through analysis of the pixel arrangement that when sub-pixels 10 whose polarities are positive are lit up, a red sub-pixel 101, a green sub-pixel 102, a blue sub-pixel 103, and a white sub-pixel 104 can be lit up. When the red sub-pixel 101 is separately lit up, a positive polarity and a negative polarity coexist, and a voltage of a common electrode is not pulled up or pulled down. In addition, on any scanning line 20, polarities corresponding to any neighboring sub-pixels are different, and a cross-talk phenomenon is avoided. Similarly, when the green sub-pixel 102, the blue sub-pixel 103, and the white sub-pixel 104 are separately lit up, phenomena such as flicker, color cast, and VCross-talk can also be effectively inhibited or avoided.
Referring to
A difference between this embodiment and Embodiment 1 is: an arrangement manner of sub-pixels 10 corresponding to each scanning line 20 is R, G, B, W, W, R, G, and B. Similarly, when sub-pixels 10 whose polarities are positive are lit up, a red sub-pixel 101, a green sub-pixel 102, a blue sub-pixel 103, and a white sub-pixel 104 can be lit up. When the red sub-pixel 101 is lit up, a positive polarity and a negative polarity coexist; and when the green sub-pixel 102, the blue sub-pixel 103, and the white sub-pixel 104 are separately lit up, the positive polarity and the negative polarity also coexist, so that phenomena such as flicker, color cast, and cross-talk can be effectively inhibited or avoided. In addition, on a same scanning line 20, polarities of any neighboring data lines 30 are different, and a VCross-talk phenomenon is avoided.

Specifically, an arrangement manner of the sub-pixels 10 corresponding to the Nth scanning line 20 (in an Nth row) is R, G, B, W, G, R, W, and B, and an arrangement manner of sub-pixels 10 corresponding to an (N+1)th scanning line 20 is W, B, R, G, B, W, G, and R. An arrangement manner of the sub-pixels 10 corresponding to the (N+2)th scanning line 20 (in the Nth row) is R, G, B, W, G, R, W, and B, and an arrangement manner of sub-pixels 10 corresponding to an (N+3)th scanning line 20 is W, B, R, G, B, W, G, and R. The rest can be deduced by analogy.
Based on the foregoing, the polarities of the data signals of the plurality of sub-pixels 10 corresponding to the same data line 30 (in a same column) are the same, and the polarities of the data signals on the neighboring data lines 30 are opposite. That is, polarities of a column of sub-pixels 10 are all positive or negative, and polarities of two neighboring columns of sub-pixels 10 are alternately positive and negative. Correspondingly, polarities of data signals of two neighboring sub-pixels 10 corresponding to a same scanning line 20 (in a same row) are opposite.
When the pixel arrangement is designed according to the foregoing structure, it may be determined that when sub-pixels 10 whose polarities are positive are lit up, a red sub-pixel 101, a green sub-pixel 102, a blue sub-pixel 103, and a white sub-pixel 104 can be lit up.

Specifically, an arrangement manner of the sub-pixels 10 corresponding to the Nth scanning line 20 (in an Nth row) is R, G, B, W, G, R, W, and B, and an arrangement manner of sub-pixels 10 corresponding to an (N+1)th scanning line 20 is W, B, R, G, B, W, G, and R. An arrangement manner of the sub-pixels 10 corresponding to the (N+2)th scanning line 20 (in the Nth row) is R, G, B, W, G, R, W, and B, and an arrangement manner of sub-pixels 10 corresponding to an (N+3)th scanning line 20 is W, B, R, G, B, W, G, and R. The rest can be deduced by analogy.
Polarities of data signals of two neighboring sub-pixels 10 corresponding to a same scanning line 20 (in a same row) are still opposite. However, a difference between this embodiment and Embodiment 5 is: polarities of sub-pixels 10 on a same data line 30 (in a same column) are different. In a same column of sub-pixels 10, polarities of data signals of two neighboring sub-pixels 10 with a same color are opposite. Arrangement structures of sub-pixels 10 in neighboring rows are different, and arrangement structures of sub-pixels 10 spaced by one row are the same. Therefore, in the same column of sub-pixels 10, colors of sub-pixels 10 spaced by one sub-pixel 10 are the same. In this embodiment, the neighboring sub-pixels 10 in the same column that have the same color are two sub-pixels 10 spaced by one sub-pixel 10, and polarities of the two sub-pixels 10 are opposite and are alternately positive and negative.
Specifically, referring to
When a pixel arrangement is designed according to the foregoing structure, it may be determined that when sub-pixels 10 whose polarities are positive are lit up, a red sub-pixel 101, a green sub-pixel 102, a blue sub-pixel 103, and a white sub-pixel 104 can be lit up. When the red sub-pixel 101, the green sub-pixel 102, the blue sub-pixel 103, and the white sub-pixel 104 are separately lit up, a positive polarity and a negative polarity coexist. Pixel polarities of sub-pixels with a same color on a same scanning line are opposite and can be balanced, so that a common electrode is not affected, to reduce a possibility of occurrence of flicker and HCross-talk. In addition, polarities of signals on two neighboring data lines are opposite, to reduce VCross-talk, improve panel display quality, and improve a yield.
The foregoing embodiments are merely optional implementations of the pixel arrangement in this application, and the phenomena such as flicker, color cast, and cross-talk can be avoided by using the foregoing pixel arrangement. The pixel arrangement is applicable to a display panel. Therefore, a display panel including the foregoing pixel arrangement and a display including the display panel also fall within the protection scope of this application.
