    • A plurality of point-light sources emits light, based on an image displayed on a display panel. A substrate has the point-light sources disposed thereon. A power-controlling section provides the point-light sources with first driving current having a pulse current with a pulse modulation duty less than or equal to a maximum pulse modulation duty cycle and a first amplitude in accordance with a normal image. A power-controlling section provides the point-light sources with second driving current having a pulse current with the maximum pulse modulation duty cycle and first boosting amplitude greater than the first amplitude in accordance with a high luminance image. Thus, the quantity of emitted light of the point-light sources may be adjusted in accordance with the position of an image displayed in a display panel, and the point-light sources that correspond to high luminance images may be boosted up.
    • 多个点光源基于显示面板上显示的图像发光。 基板上设置有点光源。 功率控制部分为点光源提供具有脉冲电流的第一驱动电流,脉冲调制占空比小于或等于最大脉冲调制占空比,并且根据正常图像具有第一幅度。 功率控制部分根据高亮度图像向点光源提供具有最大脉冲调制占空比的脉冲电流和大于第一幅度的第一升压幅度的第二驱动电流。 因此,可以根据显示面板中显示的图像的位置来调整点光源的发射光量,并且可以提高与高亮度图像相对应的点光源。
