Abstract

The present invention provides an electrowetting display panel, which includes a first substrate, a second substrate opposite to the first substrate, and more than two barrier walls on the second substrate, and the two or more barrier walls define two or more sub-pixels, an opaque insulating layer on the second substrate, the opaque insulating layer includes a dielectric layer and more than two opaque liquid units on the dielectric layer, the opaque The optical insulating layer can display black or white under the action of an electric field; two or more colored liquid units of different colors are respectively arranged between the opaque insulating layer and the first substrate corresponding to each sub-pixel, each colored liquid Cells are either conductive or polarized. The electrowetting display panel provided by the invention can realize full-color display.

Description

technical field [0001] The invention relates to the field of displays, in particular to an electrowetting display panel. Background technique [0002] The principle of the electrowetting (Electrowetting) display is to use the electrowetting phenomenon or the electrochemical capillary phenomenon. When the fluid is subjected to an electric field to change the surface free energy of the fluid, the distribution area of ​​the fluid is changed. The electrowetting phenomenon is the change of the contact angle between the electrolyte solution and the underlying insulating layer under the action of an electric field, that is, the phenomenon that the electrolyte solution shrinks or expands under the action of an electric field. The electrowetting display uses the principle of electrowetting phenomenon to display through electrodes to control ink expansion or contraction. Electrowetting display technology is more and more popular because of its characteristics of bistable display, goo...
