Automatic display system and process
First Claim
1. A display system for automatically displaying dot matrix images, said system comprising;
- a generally flat display panel having a generally vertical front plane, a panel body and a rear side, said panel being subdivided into a plurality of display modules comprising a plurality of display elements;
display sub-elements disposed in substantially adjacent relationship and forming said display elements, said sub-elements each being rotatable about a respective axis, said axes being generally parallel, and each said sub-element having a dark surface portion and a light surface portion and having actuating means for rotating said sub-element about its respective said axis;
support means rotatably supporting said sub-elements in said front plane of said panel, said support means forming said rear side of said panel; and
image setting and resetting means cooperating with said display sub-element actuating means;
said image setting and resetting means being adapted to travel behind said modules.

Abstract
An image display system and process are disclosed. The image display system comprises a generally flat display screen which is subdivided into a plurality of display mode modules, each display module being composed of a plurality of display elements. Each display element allowing the display of an image dot, comprises a plurality of display sub-elements which are hollow cylinders, having a dark half surface and a clear half surface, rotatable by 180°. Electromagnetic means are provided to actuate all display sub-elements for resetting and setting of the image. The display sub-elements of an element provide the display of the grey values of said dot.
The electromagnets of each module are controlled by a binary digital control unit.

2. A display system for automatically displaying dot matrix images, said system comprising:
-
a generally flat display panel having a generally vertical front plane, a panel body and a rear side, said panel being subdivided into a plurality of display modules comprising a plurality of rectangularly shaped display elements arranged in rows, each of said display elements comprising a plurality of adjacently disposed, elongated display sub-elements having parallel axes which lie in said front plane of said display panel;
each of said sub-elements having a dark and a white surface portion and being rotatable from a dark position in which its said dark surface portion is displayed, to a light position in which its said white surface portion is displayed;respective display sub-element actuating means fixed to each of said display sub-elements, all said actuating means of each said row of said display sub-elements defining a respective horizontal plane corresponding to said row; support means supporting said display sub-elements; and respective image setting and resetting means for each said row of said display sub-elements, said image setting and resetting means being adapted to travel behind said actuating means and being adapted to make control movements in a direction perpendicular to said vertical front plane of said display panel. - View Dependent Claims (4)

6. A process for automatically displaying a series of dot matrix images on an electromagnetically-energized display panel, said process comprising the following steps:
-
resetting an existing dot matrix image, comprising a plurality of image elements, on a display panel, said display panel comprising a plurality of display elements each of which corresponds to a respective portion of a dot matrix image displayed on said display panel, to a first condition; providing a magnetic record of an input image to be displayed on said display panel, said magnetic record comprising dot-by-dot information of the input image and having graded brightness information for each display element of said display panel; converting said magnetic record into electrical pulses and amplifying said electrical pulses to energize a plurality of electromagnets in an electromagnetic display system comprising said display panel; converting said brightness information into electrical pulses representative thereof for providing gradations of brightness in said output dot matrix image; and setting an output dot matrix image by utilizing said amplified electrical pulses to energize said electromagnets for bringing selected said display elements into a second condition to define said output dot matrix image on said display panel. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A process for automatically displaying a series of dot matrix images, said process comprising the following steps:
-
resetting an existing dot matrix image displayed on a display panel to a first condition, said display panel comprising a plurality of display elements and said resetting step comprising resetting all of said display elements into said first condition; providing a magnetic record of an input image, said magnetic record comprising dot-by-dot information of the input image; converting said magnetic record into a numerical record on a punched tape and converting said numerical record into amplified electrical pulses for energizing a plurality of electromagnets for digitally energizing an image forming system comprising said display panel; and utilizing said electrical pulses to energize said electromagnets for bringing selected said display elements to a second condition to display an output dot matrix image representative of the input image on said display panel.
