Embodiment Construction
[0032] Various embodiments of the electrowetting display of the present invention will be described in detail below, and the detailed description is as follows with reference to the accompanying drawings and reference numerals. Throughout the drawings, the same reference numerals or symbols represent the same or similar components.
[0033] The general principle of electrowetting technology is that when there is no external electric field (such as Figure 3A As shown), the colored non-polar solution 305 can be naturally dispersed on the bottom layer 306. As a comparative example, a reflective electrowetting display device can display the color of the non-polar solution 305 to the viewer. In contrast, when an electric field is applied, based on the electrowetting effect, the conductive liquid 304 will approach the bottom layer 306, causing the shape of the colored non-polar solution 305 to change, or pushing the non-polar solution 305 aside, resulting in Incident light is ref...

The invention provides an electric wettability display and a manufacturing method thereof. The electric wettability display comprises a first basal plate and a second basal plate. A plurality of first conductive electrodes are formed on the first basal plate. A second conductive layer is formed on the second basal layer, and is isolated from and not contacted with the first conductive electrodes,thereby forming an enclosure space between the second basal plate and the first basal plate. A plurality of display units are formed on the first conductive electrodes. Each display unit is formed between one of the first conductive electrodes and the second conductive layer. Every two adjacent display units are separated by a separator. At least two display units comprise a first material and a second material arranged on the first material. At least two display units have more than two different colors. The shape of the first material can change along with the change of an electric field, and the electric field is positioned between the first conductive electrodes and the second conductive layer.
Description
technical field [0001] The invention relates to an electrowetting display and a manufacturing method thereof. Background technique [0002] Reflective displays are generally regarded as one of the major display technologies for current and future applications. In recent years, many reflective displays using different technologies have been proposed. Electrowetting (Electrowetting) technology is very suitable as a reflective display, such as a high-brightness reflective color display, due to its many advantages such as fast response and no viewing angle limitation. [0003] At present, one of the conventional methods for realizing colorized electrowetting display is to use RGB color filters combined with electrowetting display elements. Compared with electrophoretic and reflective liquid crystals, this method has many advantages, such as low material cost, low power consumption, and fast response. However, part of the incident light is absorbed by the color filter, which r...
