    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.

    摘要: 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.

    摘要: Disclosed are a display device and a method of driving the same capable of improving display quality and reducing the manufacturing cost. A display device includes a display panel displaying images corresponding to image signals, a light-emission block supplying backlight to the display panel, and a backlight driver outputting a light data signal for determining luminance of backlight. One of a plurality of linear gamma curves is selected from a lookup table in accordance with average image luminance during prescribed frames, and the duty ratio of the light data signal is determined on the basis of the selected linear gamma curve. Each of the linear gamma curves represents the relationship between the average image luminance and the duty ratio of the light data signal.
