Problems solved by technology
[0005] However, the problem with the above method is that it needs to double the number of metal wiring and driving devices to drive the sub-pixels, so that the light-transmitting opening area is sacrificed, which affects the light transmittance of the panel, and the cost is also higher.

Embodiment Construction
[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0049] The display method of each embodiment will be described below by taking a liquid crystal display panel as an example. It can be understood that in other display technologies similar to liquid crystal displays, this method can also be used to solve the problem of large viewing angle deviation.
[0050] figure 2 It is a schematic diagram of liquid crystal driving structure. In the liquid crystal driving structure, a plurality of sub-pixel structures are arranged in an array, a scanning signal Si (1≤i≤m) is input in each row, and a data signal Dj (1≤j≤n) is input in each column. Generally, ...

The invention relates to a driving method of a display array and a display device. The driving method comprises the following steps: driving two optional adjacent pixel units by using relatively highvoltage driving data and relatively low voltage driving data separately; in every line, taking four adjacent pixel units as a period, and driving under the condition that the polarity arrangement of the front two lines of adjacent pixel units is different from that of the rest two lines of adjacent pixel units, wherein the polarity arrangement of the front two lines of adjacent pixel units and thepolarity arrangement of the rest two lines of adjacent pixel units are separately first polarity arrangement driving and second polarity arrangement driving; and in every row, enabling the polarity arrangement driving of every two pixel units to be the same, and alternately changing the first polarity arrangement driving and the second polarity arrangement driving by using two pixel units as a period. The display device uses the driving method. By the method and device, large viewing angle color errors can be improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving method of a display panel and a display device. Background technique [0002] Most large-size liquid crystal display panels adopt a negative vertical alignment (Vertical Alignment, VA) type or an in-plane switching (In Panel Switching, IPS) type. Compared with IPS liquid crystal technology, VA liquid crystal technology has the advantages of higher production efficiency and lower manufacturing cost, but compared with IPS liquid crystal technology, it has more obvious defects in optical properties. LCD panels suffer from color casts. [0003] When displaying an image, ideally, the brightness of a pixel should change linearly with the change of the voltage, so that the driving voltage of the pixel can accurately represent the gray scale of the pixel and reflect it through the brightness. Such as Figure 1a As shown, when VA-type liquid crystal technology i...
