ABSTRACT:
A field sequential liquid crystal display has a backlight that provides different color fields and a liquid crystal display panel that has a matrix of cells. Data lines are coupled to the cells and provide gray level data to the cells. Select lines are coupled to the cells and enable the cells. The cells include integrated memories coupled to the data lines, these integrated memories storing gray level data received via the data lines. The integration of the memories on the display panel allows all of the cells on the panel to be charged approximately simultaneously so that the time any one color is backlighting the entire display approaches an optimum fraction of a frame.
