| description | The present invention relates to an image display device. The image display device according to an embodiment of the present invention comprises: a panel; a plurality of light sources for outputting light to the panel; a plurality of switching elements for switching the plurality of light sources; and a processor for controlling the plurality of switching elements. The processor controls the level variable current to flow for each light source string among the plurality of light sources based on local dimming data. Accordingly, the present invention can improve the contrast in displaying the image.
본 발명은 영상표시장치에 관한 것이다. 본 발명의 실시예에 따른 영상표시장치는, 패널과, 패널에 광을 출력하는 복수의 광원과, 복수의 광원을 스위칭하는 복수의 스위칭 소자와, 복수의 스위칭 소자를 제어하는 프로세서를 구비하고, 프로세서는, 로컬 디밍 데이터에 기초하여, 복수의 광원 중 광원 스트링 별로, 레벨 가변된 전류가 흐르도록 제어한다. 이에 의해, 영상 표시시 컨트라스트(contrast)를 향상시킬 수 있게 된다. |
