Abstract
In accordance with the teachings of the present invention, a system and method for increasing the bit-depth of a video display system using a pulse lamp are provided. In one embodiment, the method includes illuminating a digital micro-mirror device with a light source having a variable power supply, receiving a signal indicating the light output provided to the digital micro-mirror device by the light source should be reduced to a target level during a predetermined time period, reducing a power supplied to the light source by the variable power supply in response to the signal such that the light output of the light source is reduced to about a target level during the predetermined time period, displaying a least significant bit on the digital micro-mirror device during the predetermined time period, and decreasing a speed of a master clock controlling the digital micro-mirror device in response to the light output of the light source deviating below the target level during the predetermined time period.
