Problems solved by technology

Electrowetting electronic paper is driven by voltage. After applying voltage for a period of time, due to the tension of the ink itself, there will be a problem of ink reflow, that is, the applied voltage cannot maintain the contraction state of the ink, resulting in electrowetting electronic paper. Displays the optical state of the display, i.e. the contrast or grayscale of the display is reduced

Abstract

The invention relates to a method and device for reducing backflow of a printing ink of an electrically wetted electronic paper. A driving waveform voltage displayed by a present pixel point is recorded according to detection, a present aperture ratio of a pixel of the electrically wetted electronic paper is detected, a curve is compared with an original curve to determine the backflow condition of the printing ink of the electrically wetted electronic paper, according to the backflow condition of the printing ink, an adjusting waveform is inserted into the original driving waveform, and backflow of the printing ink of the electrically wetted electronic paper is thus reduced. Thus, backflow of the printing ink of ht electrically wetted electronic paper can be reduced effectively.

Description

technical field [0001] The present invention relates to the technical field of design displays, in particular to a method and device for reducing ink reflow of electrowetting electronic paper. Background technique [0002] In recent years, electronic paper display devices have attracted much attention due to their look and feel similar to paper, low power consumption, and environmental protection. Compared with electrophoretic electronic paper, electrowetting electronic paper can also achieve high brightness, high contrast, and low energy consumption, and its response speed is faster than electrophoretic electronic paper, so it has become a key research direction for a new generation of electronic paper displays. [0003] Electrowetting electronic paper is based on the change of the contact angle of two fluids on the dielectric layer to realize the display switch. Electrowetting electronic paper is driven by voltage. After applying voltage for a period of time, due to the t...
