Driving method of multicolor electrophoretype electron paper display device with stable space

Abstract

The invention discloses a driving method of a multicolor electrophoretype electron paper display device with a stable space; electrophoresis particles are arranged in order between two electrodes according to a special driving voltage sequence, located not only on a display electrode, but also on a driving electrode surface, thus effectively improving the electrophoresis particle stability. The driving method can realize the multicolor electrophoretype electron paper storage characteristics without being affected by spatial placement positions, thus effectively reducing the electron paper refresh frequency, and saving energy and power; the driving method can provide power for a large area electron paper, so the electron paper can be easily mounted, thus effectively ensuring watching effect; the driving method can be widely applied in related fields.

Description

technical field [0001] The invention belongs to the technical field of electronic paper, and in particular relates to a driving method of a space-stable multi-color electrophoretic electronic paper display device. Background technique [0002] The principle of the multi-color electrophoretic electronic paper display device is to display images by using an electric field to make black and white particles or charged pigment particles move in a directional manner. Its basic structure is to fill the display medium layer between the two electrodes, which is composed of a certain thickness and a certain amount of charged pigment particles and electrophoretic fluid; in order to prevent the agglomeration of charged particles, the display medium layer is divided into a large number of micro cups or micro The substructure of the capsule, forming the microcup layer or microcapsule layer. When a voltage is applied across the two electrodes to form an electric field, the particles will ...

Problems solved by technology

Nevertheless, there are still many problems in the use of electrophoretic electronic paper, especially the multi-color electrophoretic electronic paper, in the spatial placement position, the spatial stability of some display states is not good

Especially when displaying black or white, with the passage of time, in a short period of time, some pigment particles will settle from one surface to the display surface, seriously affecting the clarity of the displayed content

In the spatial orientation, according to the clockwise or counterclockwise direction, the angle between the normal direction and the gravity direction of the observation side of the electronic display device is less than 90 degrees, and there is a problem with the memory of the black or white display state
