Embodiment Construction

[0037] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0038] Please refer to image 3 , is a cross-sectional view of a partial structure of a display device in an embodiment of the present invention. In this embodiment, the display device 300 includes: a first electrical substrate 310, a second electrical substrate 320, a display medium (including a hydrophobic first liquid 330 and a hydrophilic second liquid 340), a plurality of A retaining wall 360, a closed wall 370 and a light source 380, wherein the first electrical substrate 310 and the second electrical substrate 320 are arranged oppositely, and the display medium is located between the first electrical substrate 310 and the second electrical substrate 320, In addition, a plurality of barrier walls 360 are disposed on the second electrical substrate 320 to define...

Abstract

The invention provides a display device which includes a first electrical substrate; a second electrical substrate; a plurality of retaining walls which are arranged on the second electrical substrate so as to define a plurality of pixel areas; a plurality of color resistance units, each of which includes a color resistance area and a transparent area; and a display medium which fills each pixel area and includes a first liquid and a second liquid, wherein in each pixel area, when no voltage is applied, the first liquid completely covers a corresponding color resistance unit so as to prevent light from passing through the pixel area and when a voltage is applied, through an electrowetting effect, the first liquid aggregates to a side of a retaining wall, close to a corresponding color resistance area, so as to at least partly expose a transparent area in the color resistance unit to enable the light to at least pass through part of the transparent area. The display device has a comparatively high light transmittance and via a structure of combination of the non-transparent liquids and a color resistance array layer, the display device has a display effect of high uniformity and high contrast and a manufacturing procedure advantage of high yield.

Description

technical field [0001] The invention relates to the field of electrowetting display, in particular to a display device with high process yield and relatively high light transmittance. Background technique [0002] In recent years, thin and light display devices such as liquid crystal display devices have been widely used in various technical fields, and with the continuous development of display technology, the display performance of common liquid crystal display devices has reached a high standard, but in white brightness ( It mainly points out that there is still room for improvement in the technical aspect of light efficiency (display performance). [0003] Therefore, Philips first proposed a new display technology - electrowetting display technology. The so-called electrowetting (Electrowetting) technology is to use the natural forces inherent in the interface between oil and water and the methods developed to utilize these forces. This display technology was developed ...
