Abstract
A synchronized cockpit liquid crystal display (LCD) lighting system includes a backlight of the LCD, a power source to drive the backlight, a night-vision device having an adjustable gain, and a synchronization signal source. The synchronization signal source controls both the gain of the night-vision device and the power source. The synchronization signal causes the power source to drive the backlight. While the backlight is being driven, the gain of the goggles is decreased. A method of enhancing night-vision in a cockpit having at least one LCD comprises decreasing the gain of a night-vision device when the backlight is being driven by a power source. If there are multiple LCDs, their backlights are all driven at the same time. Decreasing the gain makes the ambient light from the LCDs invisible to the night-vision device.
