A method of using non-standard bits to increase brightness for a digital display system comprising a multiplicity of individual pixels for providing a spot of light wherein the color and brightness of each of said pixels is determined by combining the on time of one or more digital bits for a display frame, the method comprising: receiving an input signal for at least three colour input signals corresponding to at least three distinct colours of light (55, 57, 59), respectively, said input signal ranging from a minimum input level through a threshold input level to a maximum input level; passing light through different colored sectors of a rotating color wheel to provide said at least three distinct colors of light (55, 57, 59); and characterised by providing digital bits to each pixel of the system, the digital bits comprising a primary group of digital bits (55, 57, 59) representing the at least three distinct colors and a secondary group of digital bits comprising at least one of transitional bits, pulse bits or sector bits (87, 89, 91) representing a color different than said at least three distinct colors; defining an output brightness dynamic range between a minimum level and a maximum level, said dynamic range comprised of a first portion and a second portion; selecting a combination of digital bits from the primary group of the digital bits (55, 57, 59) in response to said input signal being between said minimum input level and said threshold input level, and wherein said threshold input level requires a combination of substantially all of said primary group of bits; selecting a combination of digital bits comprising at least one bit from the secondary group of digital bits (87, 89, 91) and selected ones of said primary group of bits (55, 57, 59) for brightness input signals between said threshold level and said maximum input level; generating a selected output brightness level of a first pixel of said display within said first portion of said dynamic range in response to a combination of digital bits selected from said primary group of digital bits and wherein said combination of selected digital bits are all selected from said digital bits of said primary group; and generating a selected output brightness level of a second pixel of said display within said second portion of said dynamic range in response to a combination of digital bits selected from both of said secondary group of digital bits and said primary group of digital bits. receiving an input signal for at least three colour input signals corresponding to at least three distinct colours of light (55, 57, 59), respectively, said input signal ranging from a minimum input level through a threshold input level to a maximum input level; passing light through different colored sectors of a rotating color wheel to provide said at least three distinct colors of light (55, 57, 59); and characterised by providing digital bits to each pixel of the system, the digital bits comprising a primary group of digital bits (55, 57, 59) representing the at least three distinct colors and a secondary group of digital bits comprising at least one of transitional bits, pulse bits or sector bits (87, 89, 91) representing a color different than said at least three distinct colors; defining an output brightness dynamic range between a minimum level and a maximum level, said dynamic range comprised of a first portion and a second portion; selecting a combination of digital bits from the primary group of the digital bits (55, 57, 59) in response to said input signal being between said minimum input level and said threshold input level, and wherein said threshold input level requires a combination of substantially all of said primary group of bits; selecting a combination of digital bits comprising at least one bit from the secondary group of digital bits (87, 89, 91) and selected ones of said primary group of bits (55, 57, 59) for brightness input signals between said threshold level and said maximum input level; generating a selected output brightness level of a first pixel of said display within said first portion of said dynamic range in response to a combination of digital bits selected from said primary group of digital bits and wherein said combination of selected digital bits are all selected from said digital bits of said primary group; and generating a selected output brightness level of a second pixel of said display within said second portion of said dynamic range in response to a combination of digital bits selected from both of said secondary group of digital bits and said primary group of digital bits.
