Display unit and display device based on microcapsule technology

Abstract

A display unit based on the microencapsulation technology comprises a fluid chamber and an electrode structure. The fluid chamber comprises a microencapsulation provided with charges and at least two types of fluid; the two types of fluid which are contacted with each other can not mix with each other; in addition, the external of the fluid chamber can not mix with the fluid; and different optical properties exist among all types of fluid. The electrode structure comprises two electrodes respectively arranged at two ends of the fluid chamber, and two openings are arranged at two ends which are opposite to each other on the chamber wall; the openings are connected with each other by an external fluid tube, so that the fluid can access to the chamber. The fluid tube is made of transparent material, and is worked as an observation surface. Voltage is added to the electrodes to generate electrical field force, thereby driving the microencapsulation with charges to move in the chamber, and further driving the fluid to flow in the chamber and the fluid tube; so that the fluid tube can show different optical properties. By adopting at least one display unit of the invention, a low-energy-consumption display device based on the microencapsulation technology can be achieved.

Description

technical field [0001] It relates to a microcapsule-based display technology and its device, especially using the electric field force to push multiple non-conductive liquids with different optical properties to flow in a closed environment composed of a chamber and a draft tube so as to realize the performance on the viewing surface. Display technologies and display devices with different optical characteristics. Background technique [0002] According to the basic knowledge of electricity, there is an electric field force between charges, charges of the same polarity have an electric field force that repels each other, and charges of different polarities have an electric field force that attracts each other. The movement of charges in a liquid under the action of an electric field is the phenomenon of electrophoresis. Many different technologies have also emerged for the development of electronic display devices and electronic paper using electric field forces and electro...

AI Technical Summary

Problems solved by technology

In the absence of a mechanism to prevent this degradation of the optical state, which must be periodically updated, updating the display consumes power, thereby reducing the usefulness of the display, and is difficult or impossible to perform without a blanking pulse (i.e. A single pixel update is accomplished with a pulse that drives the pixel to one of its extreme optical states before driving to the final desired optical state)
