Embodiment Construction

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0037] Embodiments of the present invention aim at the problem that the electrowetting display in the prior art cannot realize full-color display well, and provide an electrowetting display panel capable of realizing full-color display.

[0038] figure 2 It is a schematic structural diagram of an electrowetting display panel according to an embodiment of the present invention. The electrowetting display panel includes: a first substrate 21, a second substrate 22 opposite to the first substrate 21, and more than two substrates located on the second substrate 22. The barrier wall 23, more than two barrier walls 23 define more than two sub-pixels, the opaque insulating layer 24 located on the second substrate 22, the opaque insulating layer 24 includes a d...

Abstract

The invention provides an electrowetting display panel, which comprises a first substrate, a second substrate opposite to the first substrate, more than two retaining walls positioned on the second substrate, a light-proof insulation layer positioned on the second substrate and more than two coloring liquid units which respectively correspond to the subpixels and are arranged between the light-proof insulation layer and the first substrate and in different colors, wherein the retaining walls define more than two subpixels; the light-proof insulation layer comprises a medium layer and more than two light-proof liquid units positioned on the medium layer and is black or white under the action of an electric field; and the coloring liquid units are conductive or polar. The electrowetting display panel can realize full-color displaying.

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...
