Abstract

The invention discloses a display panel, a preparation method thereof, a driving method and a display device. The display panel comprises a first substrate, a second substrate, an electrophoresis layer and a liquid crystal layer, the first substrate and the second substrate are oppositely arranged, the electrophoresis layer and the liquid crystal layer are stacked between the first substrate and the second substrate, the liquid crystal layer faces the second substrate, a first electrode is arranged on the side, facing the electrophoresis layer, of the first substrate, a second electrode is arranged on the side, facing the liquid crystal layer, of the second substrate, and the liquid crystal layer is configured to adjust the light transmittance under the action of an electric field between the first electrode and the second electrode. The driving method comprises the step of applying corresponding voltage to the first electrode and the second electrode to adjust the light transmittance of the liquid crystal layer. By means of the driving method, multi-gray-scale display and color display of the display panel can be achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, a driving method, and a display device. Background technique [0002] As a display panel, electronic paper is mainly used in fields such as electronic labels, billboards, and e-books, and has the advantages of readability, thinness, and low power consumption. However, there are deficiencies in electronic paper display, such as slow response speed and difficulty in colorization. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a display panel, a manufacturing method thereof, a driving method, and a display device. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a display panel, including a first substrate and a second substrate oppositely arranged, and an electrophoretic layer and a liquid crystal layer stacked betwee...
