Embodiments of the present invention relate to a pixel structure, a driving method thereof and a display device.
Currently, the normal pixel design of displays is RGB or RGBW design, namely three or four sub-pixels are combined into a pixel for display, and the visual resolution is the physical resolution. However, along with higher requirement on the experience of customers on the displays, panel manufacturers need to continuously increase the visual resolution (PPI) of the displays. Currently, the means of reducing the pixel size is usually adopted to improve the physical resolution of the displays. However, when the pixel size is smaller and smaller, the manufacturing process of the displays is more and more difficult. Particularly in the process of manufacturing organic light-emitting diode (OLED) displays, the process of patterning organic matters is very difficult, so there is bottleneck in the process of manufacturing displays with higher physical resolution.
An embodiment of the invention provides a pixel structure, comprising: a plurality of closely arranged repeating groups, wherein each of the repeating groups includes linearly arranged square pixel units of different colors; each of the square pixel units in each of the repeating groups is formed by two sub-pixels with a same color and a same shape; two sub-pixels in adjacent square pixel units have different arrangement modes; and the repeating groups disposed on two adjacent parallel straight lines are staggered by a distance of one and a half square pixel units.
Another embodiment of the invention provides a display device comprising the above mentioned pixel structure.
Still another embodiment of the invention provides a method for driving the above mentioned pixel structure.

For more clear understanding of the objectives, technical proposals and advantages of the embodiments of the present invention, clear and complete description will be given below to the technical proposals of the embodiments of the present invention with reference to the accompanying drawings of the embodiments of the present invention.

Detailed description will be given below to the preferred embodiments of the pixel structure, the driving method thereof and the display device, provided by the embodiment of the present invention, with reference to the accompanying drawings.
The embodiment of the present invention provides a pixel structure, which, as illustrated in
In the embodiment, the repeating groups are formed by RGB square pixel units, but the embodiment of the present invention is not limited thereto, for instance, may further comprise square pixel units of other colors.
For instance, the case that the two sub-pixels in the adjacent square pixel units have different arrangement modes refers to that the two sub-pixels have different arrangement directions. For instance, the two sub-pixels may be arranged along the row direction or the column direction.
The pixel structure provided by the embodiment of the present invention comprises a plurality of closely arranged repeating groups; the repeating group is formed by linearly arranged RGB square pixel units; each square pixel unit in the repeating group is formed by two sub-pixels; two sub-pixels with same color and same shape in adjacent square pixel units have different arrangement modes; the repeating groups disposed on two adjacent parallel straight lines are staggered by the distance of one and a half square pixel units; and the pixel structure with the abnormal pixel arrangement is adopted to cooperate with virtual computing to achieve virtual display. That is to say, information is inputted correspondingly according to actual physical positions, and the input information is subjected to brightness redistribution and intensively outputted to the actual physical positions. For instance, when an image signal of displaying a white pixel is received, all the sub-pixels or three adjacent RGB sub-pixels in three adjacent RGB square pixel units, distributed in the shape of a delta at the position of a square pixel unit for displaying the white pixel, in the pixel structure are controlled to be switched on to display the white pixel, so that the optional switching of the sub-pixels can be flexibly applied on the premise of not reducing the pixel size, and hence the output resolution of the display image can be improved.
