Embodiment Construction

[0025] 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.

[0026] In the prior art, the instantaneous voltage of the pixel electrode and the common electrode changes drastically, and the components are easy to be damaged. In view of this, in the embodiment of the present invention, when the first driving voltage is provided to the pixel electrode with the second driving voltage, the ground voltage is first provided to the pixel electrode, and then the first driving voltage is provided to the pixel electrode, wherein the ground voltage is between the second and second driving voltages. Between the first driving voltage and the second driving voltage. This ...

Abstract

The invention is applied in the technical field of display, and provides an electrophoretic display and a drive method thereof. The electrophoretic display comprises a display panel and a source driver coupled with the display panel, wherein the display panel comprises at least one pixel unit; the pixel unit is coupled with a pixel electrode and a common electrode; when a first drive voltage is to be provided for the pixel electrode with a second drive voltage, the source driver provides a first grounding voltage for the pixel electrode with the second drive voltage and then provides the first drive voltage for the pixel electrode with the second drive voltage; and the first grounding voltage is higher than the first drive voltage and lower than the second drive voltage. Therefore, risks in damages to a component can be reduced.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to an electrophoretic display and a driving method thereof. Background technique [0002] The principle of an electrophoretic display (Electrophoretic Display) forming a picture is to use charged particles to reflect an external light source to display the picture. The electrophoretic display is light, thin and flexible, so it has attracted the attention of various manufacturers. [0003] The source driver and the gate driver of the electrophoretic display are coupled to a plurality of pixel units. The pixel unit is coupled to the pixel electrode and the common electrode. Generally speaking, the driving modes of the electrophoretic display can be divided into AC driving mode and DC driving mode. The AC driving method of the electrophoretic display is taken as an example for description below. [0004] figure 1 It is a voltage waveform diagram of the common electrode and the pi...
