A method is provided for increasing the speed at which a graphics image is displayed on a raster, such as in a liquid crystal display. The method incorporates off-line created look-up tables which are stored in memory means associated with a graphics processor unit. Thus, real time calculations are reduced resulting in a faster graphics image response time.

The invention describes a method for electronically adjusting the viewing angle of a liquid crystal display within a panel fixed in location by the structure within which it is located, such as an electronic flight indicator unit. The adjustment in viewing angle is achieved by changing the bias voltage to alter the pre-tilt angle of the liquid crystal layer.

A liquid crystal display flight indicator unit having the capability to display a horizontal situation indicator (HSI) or an attitude direction indicator (ADI) on the viewing area of the same unit. Signals from existing aircraft electronics are processed to determine whether the incoming signal is an HSI or ADI graphical image to be displayed on the viewing area. A unique component layout is described to enable HSI and ADI to be contained within a unit having a chassis size not larger than previously known HSI and ADI units.

A method is provided for creasing the speed at which a graphics image is displayed on a raster, such as in a liquid cryistal display. The method incorporates off-line created look-up tables which are stored in memory means associated with a graphics processor unit. Thus, real time calculations are reduced resulting in a fasted graphics image response time.

A method is provided in which a relatively cold lamp filament may be turned on for a brief period of time, then turned off, then turned on again, then off again, and this process repeated for successively longer periods of on time, until eventually the filament power is left on continuously. This 'pulse starting' may be controlled by a programmable microcontroller in association with a power supply to the lamp filament. The result is a longer lasting lamp filament.

Described is a backlighting module that may be used in an electronic liquid crystal display device. The backlighting includes one or more lamps within a cavity of the module. The lamps are capable of a wide range of luminance including low-level luminance achieved by a unique burst modulation scheme for driving the lamps.
