    • A backlight unit usable in an LCD for dynamically expanding color gamut of the LCD. In one embodiment, the backlight unit has a plurality of light emitting elements, and a control unit electrically coupled with the plurality of light emitting elements for controlling intensity of light emitting from each of the plurality of light emitting elements in response to a frame of image data applied to the plurality of pixels, wherein the control unit is configured such that when the frame of image data applied to the plurality of pixels is in a red color, a green color, or a blue color, the intensity of light from the red color, the green color, or the blue color emitting from each of the plurality of light emitting elements is adjusted to its corresponding maximal value so as to expand the red, the green, or the blue area of the color gamut of the LCD panel accordingly.
    • 可用于LCD的背光单元,用于动态扩展LCD的色域。 在一个实施例中,背光单元具有多个发光元件,以及与多个发光元件电耦合的控制单元,用于响应于图像帧来控制从多个发光元件中的每一个发出的光的强度 数据应用于所述多个像素,其中所述控制单元被配置为使得当施加到所述多个像素的图像数据的帧为红色,绿色或蓝色时,来自红色的光的强度 将从多个发光元件中的每一个发射的颜色,绿色或蓝色调整到其对应的最大值,以便相应地扩大LCD面板的色域的红色,绿色或蓝色区域 。
