Abstract

A display device (101) comprises a backlight unit (102) that is controllable to switch between lights of different colours, and an active panel (104) comprising a liquid crystal (LC) layer (108), a linear polarizer (110), and a drive circuit (112). Sub-images of an image are displayed by employing temporal multiplexing. Different sets of drive signals are generated for respective sub-images, based on a predefined sequence in which the sub-images are to be displayed. For each sub-image, a set of drive signals is generated to individually control LC cells of the LC layer (108), based on intensity values of pixels in the sub-image. The LC cells are controlled individually, via the drive circuit, using the different sets of drive signals according to the predefined sequence, whilst controlling the backlight unit to switch between lights of different colours according to the predefined sequence in which the sub-images are to be displayed.
