Abstract

The invention discloses a pixel structure and an electrowetting display device comprising the pixel structure. The pixel structure comprises a substrate. A first pixel electrode, a common electrode and a second pixel electrode are sequentially formed in a pixel region. A first storage capacitor is formed between the first pixel electrode and the common electrode. A second storage capacitor is formed between the common electrode and the second pixel electrode. By the adoption of the electrowetting display device comprising the pixel structure, maximization of the aperture ratio of pixels can be achieved, storage capacitance can also be enhanced, and the stability of electrowetting display is achieved.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a pixel and an electrowetting display device including the pixel. Background technique [0002] Electrowetting is one of the microfluidic phenomena, and the technology that uses the principle of electrowetting to realize display is the electrowetting display (Electro wetting Display, EWD) technology. Electrowetting display technology exploits the natural forces inherent in the oil-water interface and the display technologies developed to harness these forces. Specifically, the hydration of the hydrophobic surface of hydrophobic pigments such as dyed oil droplets is adjusted by applying a voltage, so that the dyed oil droplets spread evenly in the pixel when no voltage is applied, and are quickly pushed to the edge of the pixel after the voltage is applied, thereby realizing the color gray color. step display. [0003] The specific working principle of the EWD device is as...
