Method to display an image on a display device

摘要

In one embodiment, a method a method of displaying an image on a display device is described. The display device includes a plurality of clusters. Each cluster has a plurality of pixels and an independent light source associated therewith. Each of the plurality of clusters are illuminated with their associated independent light source. The plurality of pixels in a cluster are refreshed with bits of gray scale. Simultaneously with the refreshing, the light source associated with the cluster where the plurality of pixels are being refreshed is switched off. When the plurality of pixels have been refreshed, the light source is switched on with a predetermined intensity of light. Each of the clusters are refreshed at a rate that is fast enough to eliminate flicker.

1. A method of displaying an image on a display device, the display device having a plurality of clusters, each of the plurality of clusters having (i) a plurality of pixels, and (ii) an independent light source associated therewith, the method comprising:
a. illuminating each of the plurality of clusters with its associated independent light source, wherein the plurality of clusters are in the range of two (2) to four (4) clusters; b. refreshing the plurality of pixels in a cluster with one or more bits of gray scale; c. simultaneously with the refreshing of step (b), switching off the light source associated with the cluster where the plurality of pixels are being refreshed; d. switching on the light source associated with the cluster when the plurality of pixels have been refreshed, the light source being switched on with a predetermined intensity of light; and e. sequentially repeating steps (b)-(d) for each of the plurality of clusters at a rate that is fast enough to eliminate flicker, wherein each of the plurality of clusters is a group of either (i) only horizontal clusters of pixels when the display is scanned row-wise, or (ii) only vertical clusters of pixels when the display is scanned column-wise.
