Problems solved by technology

Although it is possible to quickly turn black after the frame area is shaken, so that the black drive frame part starts quickly, but the voltage higher than the yellow drive waveform can also drive the yellow particles to move, which cannot avoid the appearance of yellow afterimages, and at the same time reduces the contrast of the picture, which is serious. Affects the screen display of electronic paper and reduces the user experience of consumers

Abstract

The invention provides a driving waveform debugging method for eliminating residual different-color particles in display of a three-color electronic paper module. Included in sequence are balanced frame regions, Dithering frame region, a black part / a white part / a yellow part / an ACVCOM part drives a frame region; wherein the positive high-voltage waveform in the black driving frame region is a plurality of groups of positive high-voltage waveforms in a period of 20 ms or a plurality of groups of positive high-voltage waveforms in a period of non-20 ms, the positive high-voltage waveform in a single group of non-20 ms is a positive high-voltage waveform in a whole period, and the ACVCOM part is a positive high-voltage waveform in a period of 0.5-2 s; According to the technical scheme, the probability that particles in other colors appear in the picture can be effectively reduced, the display effect of the three-color electronic paper is obviously improved, and meanwhile the contrast ratio of the picture is increased.

Description

technical field [0001] The invention relates to the technical field of electronic paper, in particular to a driving waveform debugging method for eliminating residual heterochromatic particles in the display of a three-color electronic paper module. Background technique [0002] Electronic paper is a display screen made of electrophoretic display technology. It achieves the effect of displaying images by continuously applying the waveform of the driving voltage to each pixel by driving the integrated circuit. Two-color electronic paper encapsulates black and white charged particles in the same capsule structure, and three-color electronic paper refers to encapsulating charged particles of three colors, such as black, white, red, black, white, yellow, or black, white and blue, in the same capsule structure. The negative electric field controls the up-and-down movement of black, white and red particles with different charges to display black and white two-color and three-color...
