A kind of driving method of two-color electrophoretic display

Abstract

The invention provides a driving method of a double-color electrophoretic display. The driving method comprises the following steps: driving a pixel to a first color pixel by a first oscillogram; thesecond oscillogram drives the pixel to a second color pixel; each of the first oscillogram and the second oscillogram comprises a plurality of groups of micro-driving waveforms and a plurality of groups of stopping driving waveforms; wherein the micro-driving waveform is used for driving a pixel to a target pixel; wherein the stop driving waveform does not generate driving, the micro driving waveform and the stop driving waveform are alternately carried out, and in the setting driving display stage, when the waveform in the first oscillogram is the micro driving waveform, the waveform in the second oscillogram at the same driving time is the stop driving waveform; and when the waveform in the first oscillogram is a driving stopping waveform, the waveform in the second oscillogram at the same driving time is a micro-driving waveform. The electrophoretic display driven by the driving method of the double-color electrophoretic display provided by the invention is better in display effect.

Description

technical field [0001] The invention belongs to the technical field of display devices, and in particular relates to a driving method of a two-color electrophoretic display. Background technique [0002] Electrophoretic displays have the advantages of high contrast ratio, wide viewing angle, low power consumption, and bistable state. Its display effect is like ordinary paper, which makes people read comfortably, and it can switch and refresh to display new content like a common liquid crystal display. Because the use of electrophoretic display reduces the felling of wood and is conducive to the realization of green ecology, it is sought after by people. For example, the driving methods of existing e-paper (refer to figure 1 ): the first waveform 1 or the sixth waveform 6 is driven to the reverse display pixel, the second waveform 2 and the third waveform 3 are a set of refresh waveforms with opposite voltages; the fourth waveform 4 and the fifth waveform 5 Another set of ...

AI Technical Summary

Problems solved by technology

In order to solve the above problems, some researches have driven all the pixels to the target pixels in the seventh segment of the driving waveform to solve the problem caused by some pixels being driven and some pixels not being driven.

However, the seventh-segment driving waveform drives all the pixels, which cannot solve the problem of virtual patterns in reality.

If the target pattern is that one color pixel is surrounded by pixels of different colors, the seventh segment of the driving waveform drives all pixels at the same time, which will also cause the wrapped pixel to be covered.

And it consumes a lot of power to drive all the pixels at the same time, which is not economical or energy-saving
