Embodiment Construction

[0029] Please refer to FIG. 4 , which is a schematic cross-sectional view of the first embodiment of the electrowetting display of the present invention when no voltage is applied. The electrowetting display 20 includes a common electrode substrate 21, a matrix circuit substrate 22 disposed opposite to the common electrode substrate 21, and an annular sealant 29 disposed between the two substrates 21, 22, black fluid 23, various Dyed fluids 24 of different colors (including red fluid 24 a , green fluid 24 b and blue fluid 24 c in this embodiment) and a plurality of isolation walls (Pixel Wall) 26 . The ring-shaped sealant 29 is disposed on a peripheral edge of one of the substrates, and is used for laminating and supporting the common electrode substrate 21 and the matrix circuit substrate 22 .

[0030] The common electrode substrate 21 includes a first transparent substrate 210 and a common electrode layer 211 disposed on the surface of the first transparent substrate 210 . ...

Abstract

The invention relates to an electro-wetting display and a manufacturing method thereof. The electro-wetting display comprises a first substrate, a second substrate, a plurality of isolation walls arranged on the first substrate in a grid form, a plurality of pixel electrodes, lightproof masking fluid and various dyeing fluids of different colors. The minimum region structured by the adjacent isolation walls defines a sub-pixel unit. The pixel electrodes are arranged on the second substrate correspondingly to the sub-pixel units. The lightproof masking fluid fills in the sub-pixel units, and each dyeing fluid is the mixed solution of the transparent conductive solution and water-soluble dyes or water-soluble pigments; the mixed solution is incompatible with the masking fluid; all the mixed solutions respectively fill in the sub-pixel units. The incident rays from any substrate are filtered by the dyeing fluids. The electro-wetting display and the manufacturing method thereof can realize full-color display and the manufacturing cost is lower, and manufacturing method is also simpler.

Description

technical field [0001] The invention relates to an electro-wetting display (Electro-wetting Display) and a manufacturing method thereof. Background technique [0002] Electrowetting display is a new technology applied to display in recent years. It has attracted much research and attention due to its characteristics of low power consumption, wide viewing angle and high response speed. [0003] see figure 1 , is a schematic partial cross-sectional view of an electrowetting display in the prior art before pressurization. The electrowetting display 10 includes a first substrate 11 and a second substrate 17 disposed opposite to each other, and a first fluid 13, a second fluid 12, and a plurality of transparent electrodes located between the first substrate 11 and the second substrate 17. 14. An insulating layer 15 and a plurality of isolation walls 16 . The plurality of transparent electrodes 14 are arranged on the surface of the second substrate 17 in a matrix form, and ther...
