Abstract

See full text

According to one embodiment of the invention, a method for displaying N-bit color on a plurality of pixels on a monitor includes, for each pixel, receiving a value indicative of one of a plurality of possible values for the level of intensity desired to be displayed on the pixel. The value is representable by N binary bits including a least significant bit. During a given time frame, the method includes providing an on state for the pixel for a continuous fractional portion of the given time frame. The fractional portion is indicative of the received value. The given time frame includes a fixed portion followed by a variable portion. For any of the possible values for the level of intensity, the time at which the pixel is turned on during the fixed portion, if at all, is independent of the least significant bit.
