Abstract

A display drive apparatus drives a display (101) having a backlight (105) and a transmittance panel (107) comprising an array of N lines and M columns of transmittance elements for modulating the light from the backlight (105). A receiver (109) receives a plurality of time sequential frames to be displayed. A backlight driver (111) generates a backlight drive signal to switch the backlight on for at least one time interval of each frame. A transmittance panel driver (113) generates an output image by performing at least one transmittance panel drive sequence for each frame where each transmittance panel drive sequence comprises P line address operations with each line address operation providing M transmittance values corresponding to M columns of transmittance elements. Each drive sequence comprises fewer than N line address operations thereby providing faster addressing. Each sequence may e.g. address a subset of lines or may address a plurality of lines in parallel with the same value.
