Example Embodiment

[0020] First, the structure of the information display panel that is the object of the driving method of the present invention will be described. In the information display panel that is the object of the driving method of the present invention, an electric field is applied to a display medium composed of a particle group containing charged particles enclosed between two opposed substrates. Along the direction of the applied electric field, the display medium is attracted by the force based on the electric field, Coulomb force, etc., and the display medium moves in accordance with the change in the direction of the electric field, thereby displaying information such as images. Therefore, it is necessary to design the information display panel to be able to maintain stability when the display medium is moved uniformly and the display information is repeatedly rewritten or when the display information is continuously displayed. Here, as the force applied to the particles constitu...

Abstract

Provided is a method of driving an information display panel in which: at least two types of display media comprised of particle groups containing chargeable particles are sealed between opposed two substrates, at least one substrate being transparent; a voltage is applied across a pair of opposed pixel electrodes formed such that conductive films provided to the respective substrates face each other to move the display media, thereby displaying an information image, wherein, at the time of deleting the information image displayed on the information display panel, application of an alternating voltage and application of positive or negative voltage two or more cycles in a row are combined to delete the information image. With this method of driving an information display panel, it is possible to sufficiently delete a history of a previously displayed information image without causing the decrease in lifetime of display-rewriting and increase in power consumption.

Description

technical field [0001] The present invention relates to a driving method of an information display panel, and more particularly to a driving method of an information display panel used when erasing an information image displayed on the information display panel. At least two kinds of display media composed of particle groups containing charged particles are sealed between the two substrates, and a voltage is applied between the opposing pixel electrode pairs formed by making the conductive films provided on the substrates face each other to move the display media to display information. An image, wherein at least one of the two substrates is transparent. [0002] Furthermore, in the present invention, "drawing" means displaying an information image, and "erasing" means temporarily displaying a monochrome image before performing drawing. Background technique [0003] Conventionally, various methods have been known as methods for driving an information display panel in which ...
