Problems solved by technology

However, due to the viscosity of the insulating solvent filled in the microcapsules will limit the moving speed of the charged white particles, in the known display method, when switching to the next picture, some afterimages of the previous picture will appear (ghost image), which affects display quality

Embodiment Construction

[0036] figure 1 Shown is an outline icon of an e-paper display. It includes two transparent glass substrates 101 , 102 and an electronic ink layer 103 between the two glass substrates 101 , 102 . There is a common electrode on the transparent glass substrate 101 . The glass substrate 102 has electrodes. Wherein the glass substrate may also be replaced by a plastic substrate. The electronic ink layer 103 is formed by microcapsules with a diameter of 50-70 microns, and each microcapsule has black particles 108 and white particles 109 inside. When the electrodes of the glass substrate 102 are changed, the black particles 108 or the white particles 109 will move up and down according to the polarity of the electrodes, resulting in black and white display on the screen. If it is assumed that the white particles 109 are negatively charged and the black particles 108 are positively charged, when a negative charge is applied to the glass substrate 102, the black particles 108 will...

Abstract

The invention discloses a method and device for driving an electronic paper display device. The drive method comprises the following steps that: a current picture image is displayed; color data of all pixels of the current picture image is retrieved; the color data is compared so as to judge the main color system of the color data in the current picture image is biased toward undertone system data or deep color system data; and a refreshing image is displayed after the current picture image is displayed according to the judgment result.

Description

technical field [0001] The present invention relates to a driving method and a driving device, and in particular to a driving method and a driving device for driving an electronic paper display. Background technique [0002] With the rapid development of display technology, many novel display devices have been continuously developed. Among them, electronic paper display devices have many advantages such as low power consumption, thinness, long life, and flexibility, and have great potential for development. [0003] The electronic paper display device was first developed in the 1970s. It features many charged balls, one side of which is white and the other side is black. When the electric field is changed, the balls will rotate up and down to show different colors. The second-generation electronic paper display device was developed in the 1990s. It is characterized by micro-capsulations instead of traditional balls, and the micro-capsulations are filled with insulating solve...
