Abstract

The invention discloses a pixel structure, a driving method thereof, electronic paper and a display device, wherein compensation electrodes electrically connected with all pixel electrodes correspondingly are added, and an overlapping area exists between the orthographic projections of the compensation electrodes on a substrate and the orthographic projections of grid lines on the substrate, thatis, the area of the pixel electrodes is increased by using the compensation electrodes, so as to increase the aperture ratio. Furthermore, since the compensation electrode corresponding to the pixel electrode in the nth line is connected with a second electrode of a corresponding first switching transistor, and the gate of the first switching transistor is connected with a first electrode and the(n-1)th grid line, when the (n-1)th grid line is scanned, as the compensation electrode having a directly facing area with the grid line is connected to the grid line, although the added compensationelectrode has the directly facing area with the grid line, the voltages are the same, therefore coupling capacitance is not generated between the grid line and the compensation electrode, and the problem that the load is increased because the compensation electrode covers the grid line during grid line scanning is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel structure, a driving method thereof, electronic paper and a display device. Background technique [0002] With the development of digital technology, more and more display devices that disseminate information have entered people's lives, such as liquid crystal displays, which have been widely used in communication, information and consumer electronics products. However, during the display process of liquid crystal displays Continuous power supply is required, which makes electronic paper (Electronic Paper, EP), which can keep displaying for a long time even in the case of power failure, show obvious advantages. In addition, electronic paper saves power compared with liquid crystal display during use. [0003] The principle of electronic paper display is electrophoresis. The electric field formed by the pixel electrode and the common electrode drives the charged particles...
