摘要： The disclosed embodiments relate to a system and method for increasing the brightness of a video image. More specifically, there is provided a video unit (10) comprising a color wheel (14), a light source (12) configured to project a light beam at the color wheel (14), and a video control system (18) coupled to the color wheel (14) and the light source (12) and configured to decrease a supply current level for the light source (12) below a first current level during a spoke time of the color wheel (14) and to increase the supply current level above the first current level during a non-spoke time of the wheel (14).

摘要： The disclosed embodiments relate to a method and apparatus to align bit weights in a display device (10). There is provided a method for calibrating light output in a display device (10), the method comprising: displaying a first video pattern (34), the first video pattern (34) comprising a first set of pixels divided into a first subset of pixels (36a) and a second subset of pixels (36b), the first subset of pixels (36a) having a first intensity level, the second subset of pixels (36b) having an intensity level corresponding to a fully off state; measuring a first light output value associated with the first video pattern (34); displaying a second video pattern (38), the second video pattern (38) comprising a second set of pixels, each of the second set of pixels having a second intensity level corresponding to a fraction of the first intensity level, the fractional value of second intensity level being determined so that a second light output value associated with the second video pattern (38) is intended to equal the first light output; measuring the second light output value; and adjusting the fractional value of the LSB to converge the second light output value with the first light output value.
