AI Technical Summary

Problems solved by technology

Also, the need to install a dashboard with multiple displays (so adjacent displays can serve as backups) can lead to added weight and a lot of dashboard clutter
Furthermore, the display used as a backup display needs to be configured in such a way that the backup display remains readable over an extended field of view, which can result in additional power requirements or an increase in unit cost

Embodiment Construction

[0016] Reference is made in detail to the exemplary embodiments of the present invention disclosed herein, examples of which are illustrated in the accompanying drawings.

[0017] Embodiments described herein relate to systems and methods for providing display redundancy without the disadvantages of conventional redundant display implementations. A primary display and at least one backup display can be utilized. The primary display and at least one backup display may be controlled by separate graphics processors. In some embodiments, when the primary display fails, the backup display may be in place to provide the required redundancy without affecting the pilot's cross-check habitual pattern. The home spare display can be configured to operate in full mode (as opposed to a homing mode where the adjacent display is forced to serve as a spare). Furthermore, the alternate display can be provided in a variety of ways without cluttering the dashboard.

Abstract

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.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a redundant display system utilizing emissive displays. Background technique [0002] Display systems broadly include emissive and non-emissive displays. This type of emissive display refers to a display that does not require a backlight and directly produces an image. Research in the field of field emission displays, for example, provides various typical types of emission displays. Other types of displays, such as Light Emitting Diode (LED) displays, Organic-Light Emitting Diode (OLED) displays, Surface Conduction Electron Emission Displays (SEDs), and the like, may also be generally referred to as emissive displays. Non-emissive displays, on the other hand, refer to displays that require a light source. Light-modulating display devices, such as liquid crystal displays (LCDs), are non-emissive displays. [0003] In engineering, redundancy is the backup of key compon...
