Electro-wetting display panel

Abstract

The invention provides an electro-wetting display panel. The electro-wetting display panel comprises a first substrate, a first electrode, a second substrate, a second electrode, a third electrode, a hydrophobic layer and a plurality of hydrophilic retaining walls, wherein the first electrode is arranged on the first substrate; the second electrode and the third electrode are arranged on the side, facing the first electrode, of the second substrate in a staggered mode; the second electrode and the third electrode are covered with the hydrophobic layer; the hydrophilic retaining walls are located between the first electrode and the hydrophobic layer. Different pixel areas are respectively provided with first non-conductive liquid, second non-conductive liquid, third non-conductive liquid, corresponding first conductive liquid, corresponding second conductive liquid and corresponding third conductive liquid. First voltage is formed between the first electrode and the second electrode. Second voltage is formed between the first electrode and the third electrode. Compared with the prior art, the non-conductive liquid deforms by the aid of the applied voltage, so that penetration light is transmitted or reflected through opening areas. In addition, RGB are represented as the non-conductive liquid, and CYM are represented as the corresponding conductive liquid; in this way, the color gamut of the panel can be broadened, and color saturation in the process of displaying color images can be increased.

Description

technical field [0001] The invention relates to a display panel, in particular to an electrowetting display panel with better color saturation. Background technique [0002] In recent years, electronic paper (E-paper) and electronic book (E-book) are booming, and displays with lighter, thinner, and flexible features will become the main development trend in the future. The electro-wetting display is a display panel that can be applied to e-books and e-papers. [0003] In the prior art, an electrowetting display panel generally includes an upper electrode, a lower electrode, and a non-conductive liquid and a conductive liquid sandwiched between the two electrodes. When no voltage is applied, the non-conductive liquid fills the pixel area, so that the incident light can be blocked by the non-conductive liquid so that the pixel area appears in a dark state. Conversely, when it is desired to make the pixel region appear in a bright state, a voltage is applied to the upper and ...

Problems solved by technology

[0004] However, in order to display color images in the current electrowetting display panel, color dyes are generally mixed into its non-conductive liquid. If RGB three primary colors (red, green, blue) inks are used as the colored non-conductive liquid, the About 66% color conversion rate

On the other hand, if the CYM (cyan, magenta, yellow) color superposition method is used as the color non-conductive liquid, although the color conversion rate will be improved, the color gamut of CYM is narrow, and the color saturation of the display panel is very easy to appear. bad situation
