Patent ID: 8289272

Claim:
A display control system ( 11 ) comprising an input ( 12 ) for receiving an image to be displayed by means of a backlight ( 2 ) and a transmissive panel ( 3 ); a backlight controller ( 5 ) for providing a first drive signal to the backlight, the first drive signal representing at least two different colors or luminances for causing the backlight ( 2 ) to sequentially apply the at least two different colors or luminances to at least a portion of the transmissive panel ( 3 ) in at least two time-sequential sub-fields of the image; and a transmissive panel controller ( 6 ) for providing a second drive signal to the transmissive panel, the second drive signal representing at least two transmittivities for causing the transmissive panel ( 3 ) to sequentially apply the at least two transmittivities to at least a pixel of the portion of the transmissive panel in the at least two time-sequential sub-fields of the image, wherein the transmissive panel controller ( 6 ) comprises means ( 13 ) for selecting the transmittivities based on a content of the image and based on the colors or luminances of the first drive signal to display the image, wherein a remaining freedom in the selection of the transmittivities is used for selecting transmittivities having a reduced off-axis gamma distortion.
