Abstract

The invention discloses a display driving method and system of a 16-stage electrophoretic display. The method includes the following steps: A. The display controller receives the gray-scale display command and invokes the waveform lookup table; B. The display controller transmits the gray-scale waveform information to the driving electrode controller according to the gray-scale display command; C. The driving electrode controller Receive the waveform information of the gray scale, apply the voltage of the DC balance recovery waveform corresponding to the gray scale to be wiped to the pixel through the driving electrode, drive the pixel to move, and return to the basic gray scale; For the waveform information of the level, apply the voltage of the appropriate gray-scale driving waveform through the driving electrode to write the new gray level. The present invention increases the number of gray scales through the gray scale driving method, and realizes and improves the gray scale display effect of the electrophoretic display. Comply with the principle of DC balance, effectively avoiding the damage of driving electrodes and display media due to the accumulation of residual voltage.

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...
