Embodiment 1

[0034] A display panel such as figure 1 As shown, the display panel includes a sub-pixel unit array, a source driver 20, a data line array, and a scan line array; wherein, the sub-pixel unit array includes a plurality of sub-pixels 10 distributed in an array; the source driver 20 uses to provide driving signals to the sub-pixels 10; the data line array includes a plurality of data lines 30 electrically connected to the source driver 20 for receiving the driving signals of the source driver 20 and transmitting them to the sub-pixels 10; the scanning line array It includes a plurality of scanning lines 40 , each of which is connected to a row of sub-pixels 10 .

[0035] Wherein, each of the data lines 30 is connected with the same number of sub-pixels 10 as the number of rows of the sub-pixel unit array, and each row of the sub-pixels 10 has one sub-pixel 10 corresponding to one data line 30 connection; the sub-pixels 10 in each row and the sub-pixels 10 in each column include ...

Embodiment 3

[0044] A display panel such as image 3 As shown, the only difference between it and other embodiments is that the arrangement of data lines 30 is different; wherein, one of the data lines 30 is at least sequentially connected to the sub-pixels 10 located in row n A sub-pixel 10 in column m, a sub-pixel 10 in row n+2 in column m+2, a sub-pixel 10 in row n+3 in column m+2, a sub-pixel in row n+4 in column m+4 10. The sub-pixel 10 located in the n+5th row m+4 column, n is an odd number greater than or equal to 1, and m is an integer greater than or equal to 1.

Embodiment 4

[0046] A display panel such as Figure 4 As shown, the only difference between it and other embodiments is that the arrangement of data lines 30 is different; wherein, one of the data lines 30 is at least sequentially connected to the sub-pixels 10 located in row n The sub-pixel 10 in the m column, the sub-pixel 10 in the n+2th row m-2 column, the sub-pixel 10 in the n+3th row m-2 column, the sub-pixel in the n+4th row m-4 column 10. The sub-pixel 10 located at row (n+5) and column m-4, where n is an odd number greater than or equal to 1, and m is an integer greater than 4.

Abstract

The invention provides a display panel, comprising a sub-pixel cell array, a source driver, a data line array and a scanning line array, wherein the sub-pixel cell array comprises a plurality of sub-pixels distributed in an array. The data line array includes a plurality of data lines electrically connected to a source driver, wherein, each data line is connected with the same number of sub-pixelsas the number of rows of the sub-pixel unit array, and one sub-pixel is connected with a data line correspondingly on each sub-pixel of the row. The sub-pixels of each row and the sub-pixels of eachcolumn include a first pixel and a second pixel, and all the sub-pixels connected to each of the data lines are either the first pixel or the second pixel. Combining the 1 +2 row inversion mode with the column inversion mode, all the sub-pixels connected to each data line are pixels of the same polarity, and in one row scanning period, the sub-pixels on one data line only need to undergo polarityconversion once, thereby reducing the power consumption of the source driver.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a liquid crystal display device. Background technique [0002] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to inject liquid crystal molecules between the thin film transistor substrate (Thin FilmTransistor Array Substrate, TFT Array Substrate) and the color filter substrate (ColorFilter, CF), and apply pixel voltage and voltage to the two substrates respectively. The common voltage controls the rotation direction of the liquid crystal molecules through the electric field formed between the pixel voltage and the common voltage, so as to refract the light from the backlight module to generate a picture. [0003] Liquid crystal molecules have a characteristic. If the same directi...
