Abstract

The embodiment of the invention discloses an electronic paper display panel and a driving method thereof. A display area of the display panel is divided into multiple pixel units, wherein each pixel unit comprises a first pixel area and a second pixel area, and a first sub-electrode corresponds to the first pixel area and a second sub-electrode corresponds to the second pixel area in each pixel unit. The first pixel areas are used for forming a black, white or gray color at least, and the second pixel areas are used for forming colors at least so that the first pixel areas and the second pixel areas can display the same color and can also form different colors through combination. The electronic paper display panel provided in the embodiment can achieve black, white and black-white-gray scales, can also display various pure colors and different scales of colors and display more colors and is more diversified in display effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electronic paper display panel and a driving method thereof. Background technique [0002] With the development of display technology, e-paper technology is more and more widely used in e-book reading devices due to its unique advantages such as ultra-low power consumption and restoring paper visual perception. Specifically, the electronic paper technology makes the color ions in the electrophoresis move according to the magnitude and direction of the applied electric field by controlling the electric field, and maintains the position when the electric field is applied. The electronic paper display device controls the color ions in the electrophoresis to move to a preset position by controlling the electric field, and reflects them under the irradiation of external light to complete the display. [0003] However, the existing electronic paper display device can only display ...
