Title:
PLANE DISPLAY DEVICE AND PLANE DISPLAY SYSTEM
Document Type and Number:
Japanese Patent JPH07230253
Kind Code:
A
Abstract:

PURPOSE: To save the electric power even if a plane display device is enlarged in size and to obtain an image having high quality even in the day time by controlling an x-y matrix sheet for changing the magnetic field at the intersection point of an x-y matrix according to an input image signal, a memory chip sheet storing the change of the magnetic field, and a magnetic display sheet for displaying the image corresponding to the stored change of the magnetic field at the intersecting point.

CONSTITUTION: This plane display device 21 has a three-layered structure consisting of a memory chip sheet 22, a x-y matrix sheet 15 tightly adhered to this memory chip 22 so as to hold the memory chip sheet pinching it and a magnetic display sheet 23. The x-y matrix sheet 15 specifies one point of the screen corresponding to the input image signal by changing the magnetic field at the intersecting point of the x-y matrix. The memory chip sheet 22 stores the intersecting point specified by the x-y matrix sheet 15 by making this point corresponding to the change in the direction of magnetization. The magnetic display sheet 23 display the image corresponding to the specific point stored by the memory chip sheet 22.
