Three-color electrophoresis electronic paper particle quick response method and display screen

Abstract

The invention provides a three-color electrophoresis electronic paper particle quick response method and a display screen. The method sequentially comprises the following steps: an erasing stage used for driving white particles to move towards a common electrode for a duration time TE1; a reference gray scale forming stage used for driving the black particles to move towards the direction of the common electrode for a duration time TA1; a color driving stage used for driving color particles to move towards the direction of the common electrode; and a white-black driving stage used for driving the white particles to move towards the direction of the common electrode for a duration time TWB1. The driving voltage of the color particles is smaller than the driving voltage of the black particles.

Description

technical field [0001] The invention relates to a rapid response method of electrophoretic particles, in particular to a rapid response method of three-color electrophoretic electronic paper particles. Background technique [0002] The three-color electrophoretic display mainly adds red particles to the traditional black and white electrophoretic display, which increases its color diversity, but also increases the complexity of the drive. At the same time, the red particles are larger in size and slower in moving speed, and the driving time is much longer than the other two kinds of particles, which greatly affects the visual effect. The existing three-color electrophoretic driving waveform has the problem that the driving waveform period is long, and the formed reference gray scale is white, which makes the distance from the red particles to the common electrode long, resulting in a slow response time of the red particles. To solve this problem, we propose a driving wavefo...

[0002] The three-color electrophoretic display mainly adds red particles to the traditional black and white electrophoretic display, which increases its color diversity, but also increases the complexity of the drive.

The red particles in electrophoretic electronic paper are large in size and move slowly. However, the reference gray scale formed by the existing three-color electrophoretic driving waveform is white, which makes the distance from the red particles to the common electrode long, and the red display of electrophoretic electronic paper has a slow response time.
