Abstract

The invention is suitable for the technical field of displayers, and provides an electric wetting displayer and a drive method of the electric wetting displayer. The electric wetting displayer comprises a first electrode, a second electrode, an insulation layer, a pixel wall, first fluid, second fluid and a voltage exerting unit which exerts a first voltage between the first electrode and the second electrode within a first preset time period; after the first preset time period, the voltage exerting unit exerts a dynamic voltage with incremental voltage values between the first electrode and the second electrode within a second preset time period, and the voltage value of the dynamic voltage is increased into a second voltage value after the second preset time period. According to the electric wetting displayer and the drive method of the electric wetting displayer, the electric wetting device is driven by the voltage gradually increasing, so that the visual area of each pixel grid is increased, and therefore the display contrast ratio of whole pixels is increased.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an electrowetting display and a driving method thereof. Background technique [0002] In recent years, reflective display devices have attracted much attention, and one of the most attractive applications is electrowetting display devices. Because the display is realized under the control of the polar liquid in the power-on state, the response speed is faster than other reflective display devices, and it can also achieve high brightness, high contrast, and low energy consumption. The basic principle of electrowetting display is: when no voltage is applied, that is, in an equilibrium state, the colored oil wets the hydrophobic dielectric and tiles the entire unit due to its hydrophobicity, so the color appears the color of oil and the overall brightness is darker. . However, when a voltage is applied between the transparent electrode and the second electrode in contact with wat...
