  • Patent number: 9520096
    Abstract: A liquid crystal display device includes: a light source section so configured that independently-controllable emission subsections are formed on a light-exit plane of a light-guide plate; a liquid crystal display panel modulating, based on an input picture signal, light exited from each of the emission subsections in the light source section; and a display controlling section having a partitioning-drive processing section generating, based on the input picture signal, an emission pattern signal representing a light emission pattern of the emission subsections in the light source section, and a partitioning-drive picture signal. The display controlling section performs, based on the partitioning-drive picture signal, display-drive on each pixel in the liquid crystal display panel, and performs, based on the emission pattern signal, light-emission drive through allowing one or more of first light sources and one or more of second light sources to emit concurrently so as to form the emission subsections.

  • Patent number: 8890792
    Abstract: A display control apparatus may include a necessary light emission level calculation unit that calculates a necessary attention block light emission level of a back light in an attention block which satisfies a necessary luminance based on an image signal. A first neighborhood block light emission level calculation unit may calculate a light emission level of first neighborhood blocks which satisfies a deficient luminance by a light emission contribution amount to the attention block through light emission in first neighborhood blocks of the attention block which satisfies the deficient luminance by the back light in the attention block. The back light in the attention block emits the light at the largest light emission level at which the light can be emitted and back lights in the first neighborhood blocks emit the light at the first neighborhood block light emission level.

  • Patent number: 8614662
    Abstract: The present invention relates to a display control apparatus and method, and a program that are capable of appropriately controlling the luminance of light to be emitted by backlights with simple processing. On the basis of an input image signal, a peripheral-representative-value computation unit (141) computes, as a peripheral representative value, luminance that is output by backlights of a block of interest and blocks in the periphery thereof among the backlights formed from a plurality of blocks. A peripheral-contribution-amount computation unit (142) divides the peripheral representative value by light-emission efficiency based on a light-emission profile that is an output luminance distribution when the block of interest emits light so as to compute the amount of peripheral contribution by peripheral blocks to the block of interest.
