Patent ID: 8760746

Claim:
An electrowetting display, comprising: a first substrate, a second substrate disposed opposite to and under the first substrate, a plurality of separation walls, a first fluid, and a second fluid, wherein the plurality of separation walls are disposed in grid on the second substrate to define a plurality of pixel units, and the first fluid is filled in the spaces of the grid formed by adjacent separation walls, the first fluid is opaque and does not mix with the second fluid, the second fluid is transparent, has conductivity or polarity, and is filled between the first fluid and the first substrate; and wherein a colored layer is disposed for each pixel unit, and the colored layer has predetermined colors and is between the first fluid and the second substrate; wherein a control circuit is disposed for each pixel unit respectively, and the control circuit is formed on the second substrate to control a voltage difference applied between the second fluid and the second substrate for each pixel unit, so as to control the first fluid to block or expose a predetermined region of the colored layer; wherein the colored layer of each pixel unit comprises at least two regions having different colors; and at least two pixel electrodes corresponding to the regions of the colored layer one by one are disposed for each pixel unit, and the at least two pixel electrodes are provided between the first fluid and the second substrate and are both connected with the control circuit, the pixel electrodes are electrically insulated from each other.
