Publication number: 20250138378Abstract: A color electrophoretic display and a display method thereof are provided. The color electrophoretic display comprises an achromatic color particle and a plurality of chromatic color particles. The display method of the color electrophoretic display comprises turning on a stylus mode, providing an assigned stylus color, sensing a movement of the stylus to output a black trace, and transferring the black trace into a color trace of the assigned stylus color when the stylus movement stops. The black trace is shown when the achromatic color particle and the chromatic color particles move toward a top electrode, and a refresh time of the color of the black trace is smaller than 50 ms. The color of the assigned stylus color and the color of the black trace have brightness difference and at least one of the hue differences and the saturation differences.Type: ApplicationFiled: August 16, 2024Publication date: May 1, 2025Inventors: Feng-Cheng HSU, Chien-Lin CHENG, Chien-Min LAI, An-Lun HAN
