Problems solved by technology

[0005] There is a problem of contact angle saturation in electrowetting (when the voltage exceeds a certain value, the wettability no longer increases with the increase of voltage), therefore, it limits the working performance and industrial development of many devices

Abstract

The present invention provides an electrowetting color display device based on the spatial mixing method of three primary colors. The display device includes three groups of electrowetting structures of different primary colors arranged in parallel, and the electrowetting structure includes a first transparent Electrode layer, water layer, oil film layer, hydrophobic material layer, second transparent electrode layer, substrate, wherein, capillary pipe is arranged in water layer and oil film layer, and the lower end of described capillary pipe stretches into oil film layer, and the upper end passes through The second transparent electrode layer and the base pass through the base and then extend into the water layer. When the voltage is changed for the first transparent electrode layer and the second transparent electrode layer, the lower end of the capillary is always located in the oil film layer material. The present invention controls the color display of the transparent pipe on the outside of the electrowetting through the application of the capillary pipe under the action of hydrophilic force, thereby changing the occupation range of the three basic colors in the constant change of the control voltage of the control device, thereby making the color Variety.

Description

technical field [0001] The invention relates to a display structure, in particular to an electrowetting color display device based on a three-primary color space mixing method. Background technique [0002] EFD can also be called electrowetting (electrowetting) display (Electrowetting display), electrowetting refers to changing the wettability of the droplet on the substrate by changing the voltage between the droplet and the insulating substrate, that is, changing the contact angle , the phenomenon of deformation and displacement of the droplet, such as figure 1 shown. The so-called wetting refers to the process in which one fluid on a solid surface is replaced by another fluid. The liquid can spread on the solid surface, and the solid-liquid contact surface tends to expand, that is, the adhesion force of the liquid to the solid surface is greater than its cohesive force, which is wetting. The liquid cannot spread on the solid surface, and the contact surface tends to sh...
