摘要： Provided are an image processing method, an image processing device, an image processing circuit, and an image display unit that allow occurrence of a crosstalk to be reduced. When an image signal Din is input, the image signal Din is converted into an image signal D′in with a narrower dynamic range based on a lookup table (53A) on a dynamic range control section (51). At this time, the dynamic range of the image signal D′in is set up to an extent of avoiding saturation in an overdrive correction. Subsequently, an image signal Dout is generated by performing the overdrive correction for the image signal D′in using the lookup table (53A) on an overdrive control section (52).

摘要： A backlight provides uniform emanating light for a liquid crystal display. In the backlight, light emitted from a light source is incident on a receiving end surface of a light guide plate and emanates through a top surface toward a liquid crystal panel. A bottom surface includes a reflecting hollow wedge extending along the receiving end surface and varying in depth, as measured from the bottom surface, in correspondence with distance from the end surface. A dividing flat portion orthogonal to the reflecting hollow wedge divides the reflecting hollowed portion, and an output surface includes a prism having parallel ridges extending in a direction orthogonal to the receiving end surface.
