Embodiment Construction

[0020] First, the basic configuration of a charged particle moving type information display panel as one example of the electronic paper according to the present invention will be described. In the information display panel according to the present invention, an electric field is applied to a display medium sealed between two opposing substrates and composed of a particle group containing charged particles. The display medium is attracted along the direction of the electric field by electric field force, Coulomb force, etc., and information display such as an image is performed through the movement of the display medium caused by the change in the direction of the electric field. Therefore, it is necessary to design the information display panel so that the display medium can move uniformly and can maintain stability during repeated rewriting of display or continuous display of display information. Here, the force applied to the particles constituting the display medium may be...

Abstract

Provided is an electronic paper comprising two flexible substrates (1 and 2) facing each other, at least one of which is transparent, partitions (4) for partitioning the space between the two flexible substrates into a plurality of cells, and a display medium formed as particle groups and filled into the plural cells, so that the display medium is electrically driven to display information such as an image. The partitions are constituted of inter-substrate gap retaining members (4-1) arranged continuously between the two flexible substrates, and partition members (4-2) arranged discontinuously with a predetermined spacing between the two flexible substrates. As a result, a flexible panel structure can be obtained to provide the electronic paper which has a constant inter-substrate gap and a sufficient joint strength.

Description

technical field [0001] The present invention relates to an electronic paper comprising a partition wall and two flexible substrates facing each other, wherein at least one flexible substrate is transparent, and the partition wall is used to divide the space between the two flexible substrates into a plurality of units (cell), the electronic paper is characterized in that a display medium composed of particles is sealed in a plurality of cells, and the display medium is electrically driven to display information such as images. Background technique [0002] Conventionally, as a charged particle moving type information display panel in which a particle group containing charged particles is driven as a display medium, an information display panel is known in which the space between substrates constituting the panel is partitioned by partition walls; The particles are sealed in a small chamber (cell) surrounded by a partition wall; an electric field is applied between a pair of ...
