Fail-Operational Emissive Display with Redundant Drive Elements

摘要

Fail-operational display devices and methods for controlling such fail-operational display devices are disclosed. More specifically, emissive displays having independently addressable (controllable) light emitting elements fitted with redundant control circuits may be utilized. In the event of a failure, one set of redundant control circuits may be disabled while another set of redundant control circuits may be enabled to keep the display device fail-operational.

主权项

1. A display device, comprising:
at least one set of light-emitting elements; at least two redundant sets of control circuits configured to control the at least one set of light-emitting elements; and a controller in communication with the at least two redundant sets of control circuits, the controller configured to:
disable a first set of the at least two redundant sets of control circuits from controlling the at least one set of light-emitting elements; andenable a second set of the at least two redundant sets of control circuits to control the at least one set of light-emitting elements.
