A kind of electronic paper and the driving method of electronic paper

Abstract

The embodiment of the present invention discloses an electronic paper and a driving method for the electronic paper. The electronic paper includes: a first substrate and a second substrate oppositely arranged; positive liquid crystal molecules (attached to particles of the first color) filled therein; Negative liquid crystal molecules (attached to particles of the second color); a plurality of first electrodes and second electrodes are arranged on the first substrate, and a plurality of third electrodes and fourth electrodes are arranged on the second substrate; adjacent first electrodes , The second, third and fourth electrodes form a drive electrode group; wherein, the first and fourth electrodes of the same drive electrode group are energized at the first time, the second and the third electrodes are energized at the second time, and the first time Does not overlap with the second time; the angle between the electric field direction between the first and fourth electrodes and the first substrate is A, A≤30°; the electric field direction between the second and third electrodes and the first substrate The included angle is B, and B≥75°. With such setting, the normal display of the electronic paper can be realized, and the response speed of the electronic paper can be improved at the same time.

Description

technical field [0001] The invention relates to display technology, in particular to an electronic paper and a driving method for the electronic paper. Background technique [0002] Electronic paper, also known as digital paper, is an ultra-thin and ultra-light display, which can be understood as "a paper-thin, rewritable display device". Its display effect is close to the effect of natural paper, which can save users from reading fatigue. At the same time, after the display of the electronic paper is completed, the display screen can still be maintained for a long time (1 to 6 months) after the power is removed. Therefore, the power consumption of the electronic paper is low. In addition, compared with traditional liquid crystal display devices or diode light-emitting display devices, electronic paper also has the following advantages, for example, small size, light weight, easy to carry, good impact resistance, strong shock resistance, and can be used in tape and reel Pr...

Problems solved by technology

However, since electrophoretic technology relies on the movement of electrophoretic particles, its switching time for display is very long, up to hundreds of milliseconds, which cannot meet the needs of applying electronic paper to video display
