Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of display technologies, and in particular, relate to an electrophoretic display panel, a driving method thereof, and a display device. Background technique [0002] Electronic Paper (E-Paper) is a display screen made using electrophoretic display technology, which achieves the effect of displaying images by continuously applying a driving voltage waveform to each pixel by driving an integrated circuit. Two-color electronic paper encapsulates black and white charged particles in the same capsule structure. 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 ups and downs of charged particles of different charges to display black and white two-color and three-color display effects. [000...
