Embodiment Construction

[0024] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0025] refer to Figure 1-6 , an embodiment of the present invention provides a driving method for an electrophoretic display, comprising the following steps:

[0026] According to the new image requirements, the display image of the electrophoretic display is updated using the display drive waveform; in this embodiment, the display drive waveform updates the display image of the electrophoretic display in a variety of ways, such as 1. Clearing the current display image and driving it to black; 2. Drive the entire screen to white; 3. Drive to a new gray scale according to the requirements of the new image.

[0027] When the display image starts to be updated (that is, after th...

Abstract

The invention provides an electrophoretic display driving method. A display image of the electrophoretic display is updated by displaying a driving waveform,and after the display image starts to be updated, all background pixels or edge background pixels of the updated display image are driven to a background color again by using a supplementary driving signal. According to the electrophoretic display driving method provided by the invention, the ghost shadow can be well eliminated, and the display effect of the electrophoretic display is improved.

Description

technical field [0001] The invention belongs to the technical field of display devices, in particular to an electrophoretic display driving method. Background technique [0002] Electrophoretic displays have the advantages of high contrast ratio, wide viewing angle, low power consumption, and bistable state. Its display effect is like ordinary paper, which makes people read comfortably, and it can switch and refresh to display new content like a common liquid crystal display. Because the use of electrophoretic display reduces the felling of wood and is conducive to the realization of green ecology, it is sought after by people. For example, the driving methods of existing e-paper (refer to figure 1 ): 1. Clear the currently displayed image and drive it to black; 2. Drive the entire screen to white; 3. Drive it to a new gray scale according to the requirements of the new image. Due to the influence of the electric field between adjacent pixels of the electronic paper, the ...
