Embodiment Construction

[0025] Hereinafter, the preferable particle structure of the particle for display media which concerns on one Embodiment of this invention is demonstrated in detail, referring drawings. Here, in order to facilitate understanding of the present invention, an information display panel using charged type particles as display medium particles and moving the display medium particles to display images and the like is taken as an example, and its general configuration will be described first.

[0026] The information display panel of the above-mentioned charged particle movement method is used for a composite type display medium that seals the space between two opposing substrates and contains a chargeable master particle and a sub-particle on the surface. A particle group composed of particles applies an electric field. Along the direction of the applied electric field, the particles for the display medium are pulled by the force generated by the electric field, Coulomb force, etc.,...

Abstract

Disclosed are particles for a display medium for use in an information display panel which includes two substrates, at least one of which is transparent, and a display medium having an optical reflectance and electrifiability and enclosed between the substrates and in which the display medium is electrified and thereby transferred to display an information image. The particles are configured of base particles and an external additive adhered to the surface thereof, wherein the external additive comprises first external-additive particles, which are smaller particles having an average particle diameter of 7-8 nm and formed so that 80 wt.% or more of all the particles are within the range of +-2 nm, and second external-additive particles, which are larger particles formed so that particles having a particle diameter of 10 nm or smaller account for 10 wt.% or less of all the particles.

Description

technical field [0001] The present invention relates to technology related to an information display panel that encloses a display medium between at least one of two transparent substrates and moves the display medium to display information such as images. More specifically, it relates to particles for display media. These are particles constituting display media (hereinafter referred to as particles for display media), and are in a form in which an external additive is adhered to the surface of a mother particle constituting the main body of the particle. Background technique [0002] Liquid crystal display devices (LCDs) are widely used as information display devices. However, known liquid crystal display devices generally have disadvantages such as high power consumption and narrow viewing angle. Therefore, as a device instead of a liquid crystal display device, a panel for information display is proposed in which a plurality of cells separated by partition walls are for...
