DISPLAY SYSTEM AND METHOD OF OPERATION THEREFOR

摘要

A display system comprises a display panel unit (103) and a control unit (101) coupled thereto using an interface (105) providing a main video data channel and an auxiliary data channel. A video signal is generated from an input video signal and transmitted to the display panel unit (103) using the main video data channel. Furthermore, the control unit (101) determines a backlight dimming setting in response to the input video signal and transmits it to the display panel unit (103) in the auxiliary control data channel. The interface video signal may comprise pixel values that are compensated for the backlight setting. The display panel unit (103) varies the backlight dependent on the backlight indication thereby providing a display system with efficient dynamic backlight dimming. The invention may allow a standardized interface to be used when distributing display functionality between different units and may allow lower complexity display panel units with reduced form factor to be manufactured.
