Abstract

The invention provides an electro-wetting display panel, a manufacturing method of the electro-wetting display panel and an electro-wetting display device. The electro-wetting display panel comprises a first substrate, a second substrate, a dielectric layer, a plurality of sub pixel unit definition regions, first liquid and second liquid, wherein the first substrate and the second substrate are fastened together; the dielectric layer is arranged on the first substrate; the sub pixel unit definition regions are arranged between the dielectric layer and the second substrate, correspond to sub pixel units and isolated from one another; the first liquid and the second liquid are accommodated in the sub pixel unit definition regions; the first liquid can emit color light under the irradiation of excitation light; the second liquid can absorb the excitation light; when no electric filed is applied, the affinity of the dielectric layer to the second liquid is greater than that of the dielectric layer to the first liquid; and under the action of an electric filed, the affinity of the dielectric layer to the second liquid is less than that of the dielectric layer to the first liquid. The electro-wetting display panel can realize color display under the premise of not adopting a color layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an electrowetting display panel, a manufacturing method and an electrowetting display device. Background technique [0002] Electrowetting display is a technology that uses a "spread-shrink" behavior of non-polar liquids on hydrophobic dielectric films to achieve display effects. The operating principle is that when no voltage is applied to the component, the affinity of non-polar oil droplets to the hydrophobic dielectric layer (ie, the hydrophobic layer) is greater than that of the polar aqueous solution, so that the oil droplets are spread on the surface of the hydrophobic dielectric layer. When a voltage is applied to the device, the resulting charge distribution on the hydrophobic dielectric layer increases its affinity for water, driving oil droplets to be squeezed to the corners of the pixels. [0003] Fluorescence is a kind of cold luminescence phenomenon of pho...
