Embodiment Construction
[0036] The present invention will be further described below with reference to specific embodiments.
[0037] image 3 The schematic structural diagram of the electrowetting display device with the support column structure of the present embodiment, the main structure consists of the upper substrate, the lower substrate, and two immiscible polar electrolyte solutions 4 and Non-polar solution 5 composition. The upper substrate consists of an upper support plate 1 , a first electrode 2 , a sealant frame 3 , and a support column 12 , and the lower substrate consists of a lower support plate 7 , a second electrode 8 , a hydrophobic insulating layer 9 , and a pixel wall 6 .
[0038] The support column 12 is directly formed on the upper substrate 2 by physical etching or photolithography, and the shape of the support column structure 12 is a cylindrical or polygonal column structure. When the support column structure 12 is aligned with the lower substrate, in the preferred solutio...
