Abstract

The method imposes external electric field on microball cladded in microcapsule between two parallel electrode panel and the microballs are directional-moved and order-arranged under the action of the external electric field because of electric charge of itself so colour display can be obtained by totally reflecting light mating to the wavelength. Since the present invention applies method of varying external electric field i.e voltage to adjust ball arrangement state i.e ordering structure period of photon crystal, the aim of colour display can be achieved by generating different, reflection light.

Description

technical field

[0001] The invention relates to a display method and a display for a color electrophoretic display based on the concept of photonic crystals, belonging to the technical field of electrophoretic displays. Background technique

[0002] Since the electrophoretic display has performance advantages such as low energy consumption, high reflection, and wide viewing angle, extensive research has been done on this technology. However, in the initial research work, the electrophoretic display could not work stably due to particle agglomeration and migration, so it has not been commercially applied. In 1997, B.Comiskey et al. of E-INK Corporation of the United States proposed the method of constructing electrophoretic display (also known as electronic paper) with microcapsules. This method successfully solved the problem of particle agglomeration and migration, thus making electrophoretic display effective possibility of commercial application. Most of the currently r...
