Abstract
Official abstract text for this publication.
A driver circuit drives a plurality of groups of light emitting elements. Each element includes an anode, a cathode connected to the ground, and a gate that controls electrical conduction between the anode and cathode. A first driver section simultaneously drives the anodes of the elements of the plurality of groups of elements. A second driver section simultaneously drives the gates of the elements in a corresponding group of the plurality of groups. The second driver section includes a series connection of a first switch element and a voltage level shifter. The series connection is connected between a power supply and the group of gates. The second driver section further includes a second switch element connected between the group of gates and the ground.
First claim
Opening claim text (preview).
What is claimed is: 1. A driver circuit for use with a power supply to drive a plurality of groups of light emitting elements, each light emitting element including a first terminal, a second terminal connected to a node at a predetermined potential, and a third terminal that controls electrical conduction between the first terminal and the second terminal, the driver circuit comprising: a first driver section commonly connected to the first terminal of a first light emitting elem…
