Image processing device comprises a maximum luminance setting unit that associates a maximum luminance value included in a corresponding area of a luminance image with each of a plurality of areas obtained by classifying a display area of a second liquid crystal panel into multiple areas to include an overlapping area overlapping a plurality of first pixels of a first liquid crystal panel for one pixel, an order setting unit that sets the order of the plurality of areas in descending order of maximum luminance values, and a transmittance setting unit that sets the transmittance of the pixel of interest based on the maximum luminance value are provided. The transmittance setting unit sets the transmittance of the pixel of interest based on a transmittance coefficient indicating a proportion at which each of the plurality of first pixels overlapping the overlapping area influences the overlapping area with transmitted light.

Image processing device, image display device, and image processing method

A display device includes: light-emitting elements in a backlight divided into a plurality of areas, the light-emitting elements being arranged in such a manner as to correspond to the plurality of areas; and a drive unit configured to drive the light-emitting elements in the plurality of areas by time division based on an input image every prescribed period of time, the drive unit turning on all the light-emitting elements in the plurality of areas in a partial period of the prescribed period of time and driving those light-emitting elements in at least one of the plurality of areas based on the input image in a remaining period of the prescribed period of time.

Display device

In a display device, a drive circuit drives LEDs arranged in n rows (n is an integer equal to or greater than two) so as to correspond to a plurality of areas of a backlight, row by row through division into n time slots or every k rows (k is an n's divisor equal to or greater than two and is smaller than n) through division into n/k time slots in accordance with the status of use of the display device.
