Abstract

The invention provides a color electrophoretic display device and a display driving method thereof. The color electrophoretic display device comprises a display panel and a display driver, and is characterized in that the display panel comprises a plurality of pixels; the display driver is electrically connected to the display panel and used for driving the pixels of the display panel to display one of a variety of colors by using a plurality of driving signals with different signal waveforms; the driving signals comprise a first driving signal and a second driving signal; and the display driver selects the first driving signal or the second driving signal according to image data, and drives at least one of the pixels of the display panel by using the first driving signal or the second driving signal to display one of multiple gray colors or black colors with different grayscale values in the colors so as to provide good display quality.

Description

technical field [0001] The present invention relates to a display device and its display driving method, and in particular to a color electrophoretic display device and its display driving method. Background technique [0002] Due to the influence of manufacturing process and materials, after the reliability analysis of color electrophoretic display (EPD) at various temperatures, the same low voltage is used to drive particles of a specific color, and it can be found that different test conditions will appear different. driving results. In order to solve this problem, the driving waveform used to drive the particles of a specific color is specially designed to solve it. However, this driving waveform may be affected by particle diffusion factors, causing a border of other colors to appear at the junction of a specific color and black. This frame spreads heavily to the black part, which will be different from the original image display. Contents of the invention [0003]...
