Abstract

The embodiment of the invention provides an electrowetting display panel and a driving method thereof and relates to the technical field of display, aiming at realizing multi-gray-scale display. According to the electrowetting display panel, each sub-pixel region is provided with an electrowetting box unit; each electrowetting box unit comprises a first substrate and a second substrate which are arranged oppositely, and a light emitting plate which is located between the first substrate and the second substrate and emits light toward the second substrate; a first space is formed between the light emitting plate and the first substrate and a second space is formed between the light emitting plate and the second substrate; the light emitting plate is provided with at least two through holeswhich are formed nearby edges of two opposite sides of each electrowetting box unit; under illumination, the first space and the second space are filled with hydrophilic fluid which is colorful and lightproof lyophobic fluid; the hydrophilic fluid and the lyophobic fluid are not dissolved with each other; a lyophobic layer is arranged on at least one surface of the upper surface and the lower surface of the first space; each electrowetting box unit further comprises a conducting structure for forming an electric field and the electric field formed by the conducting structure is acted on the lyophobic layer; the second substrate is transparent.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an electrowetting display panel and a driving method thereof. Background technique [0002] Electrowetting (Electrowetting) display technology has attracted more and more attention due to its characteristics of low power consumption, sufficiently fast response speed, low cost, and no light leakage. At this stage, electrowetting display technology is still in its infancy, but its superior performance and development potential indicate the future display technology. [0003] Most of the current electrowetting display devices can only display black and white, which greatly limits the application of the electrowetting display device. Contents of the invention [0004] Embodiments of the present invention provide an electrowetting display panel and a driving method thereof, which can realize multi-grayscale display. [0005] In order to achieve the above object, embodimen...
