Abstract

A liquid crystal display (1100) is disclosed, comprising a liquid crystal display panel (1102), a backlight unit, and a controller (1104, 1200, 1300). The liquid crystal display panel (1102) comprises a plurality of picture elements, wherein said picture elements are refreshed repeatedly, said backlight unit comprises a plurality of lighting devices (1105) each associated with a section of the display panel (1102) and arranged to provide backlighting to said section of the display panel (1102), and said controller (1104, 1200, 1300) is arranged to control timing, between refresh of picture elements and said backlighting by the lighting device corresponding to the section of the picture elements to be refreshed, in dependence on a position of the section associated with said corresponding lighting device. The controller comprises a backlighting controller for each of said sections, which backlighting controller is arranged to control backlighting timing depending on said position of said each section, wherein said control of backlighting timing comprises an advance, related to a refresh timing of corresponding picture elements, of backlighting timing for sections at a first end of said display panel, and a delay, related to a refresh timing of corresponding picture elements, of backlighting timing at a section at a second end opposite to said first end of said display panel (1102).
