摘要:
A backlight unit for a display device that reduces power consumption while and display of undesirable artifacts in images is presented. The backlight unit is divided into a plurality of light-emitting regions, and a luminance control signal generator controls the luminance of light emitted by each of the light-emitting regions. The luminance of a particular light-emitting region is controlled by taking into account light interference from an adjacent light-emitting region. A display panel to display images through light emitted from the backlight unit, and a backlight driver drives the backlight unit.

A method of driving a light source including a light-emitting block includes generating a luminance representative value based on an average grayscale value and a maximum grayscale value extracted from an image signal corresponding to the light-emitting block. The method further includes detecting a predetermined pattern of the light-emitting block, generating a compensation control signal based on the predetermined pattern, generating a compensated luminance representative value by compensating the luminance representative value based on the compensation control signal, and driving the light-emitting block based on the luminance level of the light-emitting block corresponding to the compensated luminance representative value.

A liquid crystal display apparatus includes an LCD panel assembly. A backlight assembly includes a light source that irradiates the LCD panel assembly. A light-sensing part generates a detection signal corresponding to a quantity of the light. A reference signal-generating part generates a reference signal corresponding to a reference quantity of the light. A control signal-generating part compares the detection signal with the reference signal to generate a control signal. A backlight assembly-controlling part controls the luminance of the light source in accordance with the control signal.
