Abstract

The invention provides an electro-wetting pixel structure, which comprises a base plate, a hydrophobic dielectric layer, non-polar liquid, at least one electrode and at least one conducting hole. The electrode is formed on the base plate and divides the base plate into an electrode area and an electrode-free area, and when a voltage is applied to the electro-wetting pixel structure, the non-polarliquid is shrunk to a position where the electrode-free are is substantially superposed on the hydrophobic dielectric layer. The conducting hole is formed in the base plate and positioned at a position far from the electrode-free area of the electro-wetting pixel structure.

Description

technical field [0001] The present invention relates to the technical field of electrowetting displays, in particular to an electrowetting pixel structure. Background technique [0002] Figure 1A and Figure 1B A schematic cross-sectional view of a display unit 100 of a known electrowetting display is shown. Such as Figure 1A and Figure 1B As shown, the display unit 100 includes a polar aqueous solution 102 , black ink 104 and a hydrophobic dielectric layer 106 . Such as Figure 1A As shown, when no voltage is applied, the black ink 104 will uniformly cover the upper surface of the lipophilic dielectric layer 106, so ambient light or backlight will be absorbed and appear black to form a dark state. vice versa Figure 1B As shown, when a voltage source 116 is used to apply a voltage to the transparent electrode 108, the interface between the lipophilic dielectric layer 106 and the aqueous solution 102 is polarized to increase the effective surface energy, so that the l...
