Abstract

The invention discloses a display driving method and system for a sixteen-order electrophoretic display device. The method comprises the following steps: A. receiving a gray scale display command by virtue of a display controller, and calling a waveform query table; B. transmitting waveform information of gray scale to a drive electrode controller by virtue of the display controller according to the gray scale display command; C. receiving the waveform information of the gray scale by virtue of the drive electrode controller, exerting voltage of DC balance restoration waveform, corresponding to a to-be-wiped gray scale, on a pixel through the drive electrode, moving the pixel and returning to a basic gray scale; and D. after completing wiping through the drive electrode controller, exerting appropriate gray scale driving waveform voltage through the drive electrode according to the waveform information of the gray scale so as to flash a new gray scale. The method and the system disclosed by the invention, through the gray scale driving method, can improve gray scale order, and can implement and improve the gray scale display effect of the electrophoretic display device. The method and the system, on the basis of DC balance principle, can effectively avoid damage of the drive electrode and a display medium due to residual voltage accumulation.

Description

technical field [0001] The invention relates to a display driving method and system for a 16-stage electrophoretic display, belonging to the technical field of electrophoresis. Background technique [0002] Microcapsule electrophoretic display has become an important electronic paper display technology. Compared with other display technologies, it has the advantage of ultra-low power consumption, so electrophoretic display technology is widely used. There are two kinds of particles in the microcapsules: black particles and white particles. White particles are governed by negative charges and black particles by positive charges. Therefore, when the pixel electrode is supplied with a negative voltage, the electrophoretic display displays white, and when driven with a positive voltage, it displays black. The electrophoretic display needs an active matrix backplane. In order to drive the electrophoretic particles to achieve the correct display of the gray scale, a suitable dri...
