Technical Field
The invention relates to the technical field of display, in particular to a pixel structure, a liquid crystal display panel and a liquid crystal display device.
Background
Among flat panel Display devices, a TFT-LCD (Thin Film Transistor Liquid Crystal Display) has the characteristics of small volume, low power consumption, relatively low manufacturing cost, no radiation, and the like, and occupies a leading position in the current flat panel Display market.
The refresh rate refers to the speed at which pictures are updated on the screen, i.e., the number of times a picture appears on the screen per second. The standard refresh rate for TFT-LCDs is typically 60 Hz. In order to reduce power consumption, a display scheme combining low frequency and standard frequency has been proposed in the industry at present, and specifically, when a dynamic picture is displayed, in order to ensure the display effect, a standard refresh frequency of 60Hz is still adopted; when displaying a static picture, a lower refresh rate is used, e.g. the refresh rate is reduced to 1 Hz.
In order to avoid polarization of liquid crystal molecules, the liquid crystal panel is usually driven by alternating positive and negative voltages, and the driving voltage of each sub-pixel is inverted in polarity during frame updating. The polarity inversion method includes frame inversion, column inversion, row inversion, dot inversion, and the like, wherein the power consumption of the column inversion method is low, and the column inversion method is also a polarity inversion method that is commonly used at present.
The prior art has the defect that when the liquid crystal display device displays low frequency in a column inversion mode, the brightness difference of different columns can be seen on a picture due to the different brightness generated by the sub-pixels driven by positive voltage and negative voltage, which is also called mura phenomenon, and especially when a monochrome picture is displayed, the brightness difference is more obvious.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
As shown in fig. 1 to 4, fig. 1 is a schematic diagram of a pixel structure according to an embodiment of the invention, and each sub-pixel is not lighted; FIG. 2 is a schematic diagram of three adjacent data lines connected to a sub-pixel in a pixel structure according to an embodiment of the invention; FIG. 3 is a schematic diagram of a pixel structure displaying red color according to an embodiment of the present invention, wherein a red sub-pixel is turned on; fig. 4 is a schematic diagram of a pixel structure displaying white according to an embodiment of the invention, in which the red sub-pixel, the green sub-pixel, and the blue sub-pixel are all turned on.
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a pixel structure, which includes a group of gate lines 1, a group of data lines 2, and a plurality of sub-pixels arranged in a dot matrix, where different sub-pixels connect different combinations of gate lines 1 and data lines 2, where: the sub-pixels in two adjacent rows are arranged in a staggered manner, and the sub-pixels in two adjacent columns are arranged in a staggered manner; each row of sub-pixels comprises a first sub-pixel 31, a second sub-pixel 32 and a third sub-pixel 33 which are different in color and are circularly arranged, and any first sub-pixel 31 is positioned on the central line S1 of the adjacent second sub-pixel 32 and third sub-pixel 33 of the adjacent row; the color of each column of sub-pixels is the same, and the adjacent sub-pixels are respectively connected with different data lines 2.
The first sub-pixel 31, the second sub-pixel 32 and the third sub-pixel 33 are different in color but not limited to specific color, and may be, for example, a red sub-pixel, a green sub-pixel and a blue sub-pixel, respectively, or a green sub-pixel, a blue sub-pixel and a red sub-pixel, respectively, and so on. In the embodiment of the present invention, two adjacent rows of sub-pixels are arranged in a staggered manner, two adjacent columns of sub-pixels are arranged in a staggered manner, and any first sub-pixel 31 is located on the center line S1 of the adjacent second sub-pixel 32 and the adjacent third sub-pixel 33 in the adjacent row, that is, the first sub-pixel 31 and the adjacent second sub-pixel 32 and the adjacent third sub-pixel 33 in the adjacent row are arranged in an isosceles triangle, and the first sub-pixel 31 is located at the vertex position of the isosceles triangle. The arrangement is such that sub-pixels of the same color are arranged in a column. Macroscopically, each of the first subpixel 31, the second subpixel 32, and the third subpixel 33 arranged in an isosceles triangle forms one pixel unit 100.
In the liquid crystal display panel, each sub-pixel needs to be connected with a gate line 1 and a data line 2, a thin film transistor serving as a switching element is turned on by receiving a scanning signal of the gate line 1, and liquid crystal molecules are driven to deflect by receiving a voltage signal of the data line 2, so that the sub-pixel displays a certain gray scale. Different sub-pixels connect different combinations of the gate lines 1 and the data lines 2, so that each sub-pixel can independently emit light. The different color sub-pixels of the pixel unit 100 are mixed according to a certain gray scale, so that the pixel unit 100 can macroscopically display various colors.
When the liquid crystal display panel displays a frame of picture, scanning signals are sequentially transmitted to each grid line 1, the thin film transistors of the sub-pixels connected with the grid lines 1 are turned on, and the sub-pixels receive driving voltage signals transmitted by the respective data lines 2, so that corresponding display is performed. In order to make the human eye see smooth dynamic pictures, the refresh frequency of the lcd panel is usually 60Hz, i.e. the pictures are refreshed 60 times per second. When the liquid crystal display panel displays a static picture, the refresh frequency may be reduced, for example, a refresh frequency of 1Hz is used to reduce power consumption because the picture content is not changed.
In the prior art, a column of sub-pixels with the same color is usually connected to a data line, and a driving voltage signal is transmitted by the data line. When the liquid crystal display panel displays in a low frequency mode in a column inversion mode, at any moment, two adjacent columns of sub-pixels are respectively driven by positive voltage and negative voltage, and because the liquid crystal molecules are driven by the positive voltage and the negative voltage, the deflection angles are different, the brightness difference generated by the two adjacent columns of sub-pixels is obvious, and particularly when a single-color picture is displayed, the brightness difference is more obvious.
As shown in fig. 3 and 4, the liquid crystal display panel adopts the pixel structure of the above embodiment of the present invention, and the adjacent sub-pixels in the same column respectively transmit the driving voltage signals with opposite polarities through different data lines, that is, in the sub-pixels in the same column, the sub-pixels driven by the positive voltage and the negative voltage are alternately arranged, and the sub-pixels in two adjacent columns of the same color are alternately arranged, so that the phenomenon of uneven brightness during low frequency display of the display screen can be effectively improved macroscopically, and the display quality is improved.
In the embodiment of the invention shown in fig. 1, each column of sub-pixels is alternately connected to two data lines 2; each data line 2 is located between two adjacent columns of sub-pixels and has a rectangular wave shape. As shown in fig. 2, each sub-pixel connected to each data line 2 includes a plurality of circulation units 10, each circulation unit 10 includes four sub-pixels in different columns and different rows, and the four sub-pixels include a first sub-pixel 31, a second sub-pixel 32, and a third sub-pixel 33. Namely: each circulation unit comprises three colors of sub-pixels and comprises two same colors of sub-pixels.
As shown in fig. 1, in the preferred embodiment of the present invention, any first sub-pixel 31 is arranged in a regular triangle with the adjacent second sub-pixel 32 and the third sub-pixel 33 of the adjacent row. With this design, more sub-pixels can be arranged, thereby improving the resolution of the liquid crystal display panel.
An embodiment of the present invention further provides a liquid crystal display panel, including the pixel structure according to any of the foregoing technical solutions, wherein polarities of driving voltage signals of adjacent sub-pixels located in the same column are opposite. Compared with the prior art, the liquid crystal display panel has the advantages that the phenomenon of uneven brightness during low-frequency display is effectively improved, and the display quality is high.
The embodiment of the invention also provides a liquid crystal display device which comprises the liquid crystal display panel in the technical scheme. Compared with the prior art, the liquid crystal display device has the advantages that the phenomenon of uneven brightness during low-frequency display is effectively improved, and the display quality is high.
The liquid crystal display device may be a low frequency display liquid crystal display device, and the picture refresh frequency is less than 60Hz, for example, the picture refresh frequency is 1 Hz. The liquid crystal display device can also be a liquid crystal display device with low-frequency display and standard-frequency display, and has a first working state with the picture refreshing frequency of 60Hz and a second working state with the picture refreshing frequency less than 60Hz, wherein the liquid crystal display device is in the first working state when displaying a dynamic picture and in the second working state when displaying a static picture.
The specific product type of the liquid crystal display device is not limited, and for example, the liquid crystal display device may be a liquid crystal advertisement screen, a liquid crystal display, a liquid crystal computer, a tablet computer, or the like.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention.
