The liquid crystal display panel of the present invention provides rapid highlighting of the display. To provide highlighting, current to the backlighting lamp is increased from a normal current to a highlighting current. During the transition from the normal current to the highlighting current, the current to backlighting lamp is increased to an intermediate current above the highlighting current, and then decreased to the highlighting current. The increase to an intermediate current provides greater energy to the backlighting lamp than a direct increase from the low current to the highlighting current. The increased energy heats the backlighting lamp quickly to provide the increased light for highlighting. In addition, reducing the current to the backlighting lamp below the normal current when leaving the highlighting mode decreases the time to leave the highlighting mode.
