1. A monolithic light-emitting array comprises:
- an array of light-emitting elements having a common substrate and each having a gate and an anode, said light-emitting elements being made of compound semiconductor and including ON state transferring functions;
coupling means for electrically coupling the gate of one of said light-emitting elements to the gate of the next light emitting elements so that the conducting light-emitting element will cause the next light-emitting element to turn on upon applying energy through its anode;
at least two transfer lines each connected to anodes of every at least two light-emitting elements; and
polyphase clock means connected to said transfer lines to provide for transferring a conducting state from one light-emitting element to the next.

Abstract
A self scanning light-emitting array is disclosed. A coupled array of light-emitting elements is constituted so that a light-emitting element in a minimal conducting state influences the next light-emitting element so that its threshold level is changed. When each element is driven by a common clock pulse, the change in threshold level is shifted in the longitudinal direction, so that a minimal conducting state is transferred in a clock period of the clock pulse.

-
an array of light-emitting elements each having a gate and an anode and including an ON state transferring function; coupling means for electrically coupling the gate of one of said light emitting elements to the gate of the next light emitting elements so that the minimal conducting light emitting element will cause the next light-emitting element to minimally turn on upon applying energy through its anode; at least two transfer lines each connected to anodes of every at least two light-emitting elements; polyphase clock means ORed to said transfer lines to provide for transferring a minimal conducting state from one light-emitting element to the next; and a current source having outputs each ORed to said transfer line to provide an additional current to said minimal conducting light-emitting element. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
