Method for reducing flicker in switching screens of electrophoretic display and electrophoretic display

Abstract

The method for reducing the flickering of the switching screen of the electrophoretic display and the electrophoretic display of the present invention, the method includes: receiving the target gray scale information displayed by the pixel point; determining the DC balance supplementary driving signal according to the new gray scale driving signal of the previous state of the pixel point Drive waveform of the driving waveform; the pixel point is driven from the original gray scale to the first extreme state through the first extreme state driving signal; the pixel point is driven from the first extreme state to the second extreme state through the second extreme state driving signal, and then DC is applied The balance compensation drive signal keeps the electrophoretic display DC balanced, and then converts the pixel to the target gray scale by writing a new gray scale drive signal; the voltage polarity of the second extreme state drive signal is the same as the voltage polarity of the DC balance compensation drive signal The same; the present invention integrates each stage of the driving waveform by optimizing the driving waveform, which can reduce the number of flickering of the display screen of the electrophoretic display device and improve the comfort of the electrophoretic electronic paper screen switching.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a flicker reducing method for switching images of an electrophoretic display and the electrophoretic display. Background technique [0002] EPD (electrophoresis) electronic paper: Electrophoretic electronic paper has become a very important information display carrier. It has been widely used in e-book readers, electronic tags, electronic billboards, etc., and it has good bistable characteristics. During static display, it consumes almost no power, which is a display technology with energy-saving and environmental protection characteristics. However, there are still a series of shortcomings in electrophoretic electronic paper, such as: slow response speed, poor picture display quality, flickering phenomenon when switching pictures, etc.; these shortcomings seriously affect the display effect of electrophoretic electronic paper and restrict the scope of market application . The...
