ABSTRACT:
In a LCD monitor, a predetermined part (PA) of the displayed information is highlighted by causing the backlighting (BLU) to produce more light. The area outside the predetermined area (PA) is kept at a substantially constant brightness by adjusting the video data driving the panel (LCD). A booster (BO) is added to control the lamp (BLL) such that the amount of light produced by the backlighting (BLU) increases in a controlled and predictable way so the user does not notice a transition in terms of brightness in the area outside the predetermined area (PA).
