Patent ID: 8643934

Claim:
A display, comprising: a pixel array substrate, comprising: a first substrate comprising a plurality of pixel regions, each of the pixel regions comprising a distribution region of pixel electrode and a non-electrode region; a plurality of pixel structures disposed in the pixel regions, wherein each of the pixel structures comprises: a pixel electrode disposed in the distribution region of pixel electrode and having at least one slit, an extension direction of the at least one slit extending from the non-electrode region toward the distribution region of pixel electrode, the pixel electrode further comprising at least one protrusion extending from the distribution region of pixel electrode to the non-electrode region; an insulating layer covering the pixel electrode; and a hydrophobic layer covering the insulating layer; a fluid medium comprising a polar fluid and a non-polar fluid; and an opposite substrate, comprising: a second substrate; and a common electrode disposed on the second substrate and contacting the polar fluid, wherein the polar fluid and the non-polar fluid are present between the first substrate and the second substrate, and the non-polar fluid is contracted toward the non-electrode region when a voltage difference is generated between the pixel electrode and the common electrode.
