Abstract

This equipment is a dynamic, lampless display device. Endless tape 10 is movably supported on drive pulley 11 and idler pulley 12 and is adapted for either continuous or incremental movement. Tape 10 has a plurality of rows of tabs or flaps 13 pivotally attached to it. Flaps 13 are adapted to be actuated to one of the binary states by program controlled electromagnets 14. Surfaces 13a are coated with a light sensitive material such as a phosphorescent paint. In their actuated condition, flaps 13 ride on support rods 15 and are thus held with the painted surfaces in close proximity to display screen 16.

Data Display Device

This equipment is a dynamic, lampless display device. Endless tape 10 is movably supported on drive pulley 11 and idler pulley 12 and is adapted for either continuous or incremental movement. Tape 10 has a plurality of rows of tabs or flaps 13 pivotally attached to it. Flaps 13 are adapted to be actuated to one of the binary states by program controlled electromagnets 14. Surfaces 13a are coated with a light sensitive material such as a phosphorescent paint. In their actuated condition, flaps 13 ride on support rods 15 and are thus held with the painted surfaces in close proximity to display screen 16.

The light emission properties of flaps 13, when subjected to ambient light, cause a dot or bit-formed character representation to visibly appear on screen
16. The characters formed in this manner can constitute messages which can be displayed cyclically or with new messages generated under program control of electromagnets 14. The apparatus operates without the need for a arrangement of lights.

After flaps 13 have traversed the length of screen 16 they can be reset to the other bistable state by reset devices, not shown.
