An inexpensive system for maintaining an LCD display above an operative temperature includes ultraviolet (UV) light-emitting diodes (LEDs) incorporated into a backlight structure. The UV LEDs operate in a frequency range sufficiently removed from the visible band to not interfere with the user. A temperature sensor continuously or periodically monitors the temperature of the LCD and activates the UV LEDs to maintain the LCD in a predetermined temperature range for a desired response time.

System and method to heat LCDs using UV LEDs

Redundant display systems and methods for providing display redundancy are disclosed. A display system may include a primary display and at least one secondary display. The primary display and the at least one secondary display may be stacked in series relative to a line of sight of a user, and the at least one secondary display may be configured to serve as a backup to the primary display upon a failure of the primary display.

Redundant display system using emissive display

An emissive avionics display unit includes a thin, flexible emissive display surface that may be resized for reuse in a larger or smaller housing. The display surface may be removed from its housing and folded over, rolled over, or cut along an axis of the surface so that a smaller visible portion remains on which images may be displayed by the emissive display unit's drive electronics. The display surface may also be increased in size by unfolding or unrolling previously folded or unrolled portions. Resizing allows the emissive display surface and its drive electronics to be reused or customized to fit display housings of nonstandard shape or size, which housings may in turn be designed to conform to a broad variety of cockpit sizes and available surface areas.
