摘要： An embodiment of a liquid crystal display device includes: a liquid crystal panel including pixels arranged in a pixel; and a backlight that irradiates it with light. In at least one example embodiment, the pixels included in the liquid crystal panel each include picture elements different in color. The picture elements are each provided with a color filter corresponding to the color of the picture element. The liquid crystal display device includes: an aperture ratio converting section that, to reduce optical cross talk, decreases an aperture ratio for inputted image data and outputs data of the aperture ratio; and a backlight data converting section that, to supplement the aperture ratio for the image data which is decreased by the aperture ratio converting section, converts data to increase a backlight luminance. This backlight luminance control prevents or reduces optical or electrical cross talk.

An APL calculating unit (16) obtains, based on an input image (31), an average luminance level of the image for one frame. A luminance range determining unit (151) determines an upper limit value and a lower limit value of luminances of LEDs, based on the average luminance level. An area active drive processing unit (15) obtains, based on the input image (31), liquid crystal data (32) used to drive a liquid crystal panel (11) and LED data (33) used to drive a backlight (13). When the LED data (33) is obtained, the input image (31) is divided into a plurality of areas and a luminance of LEDs corresponding to each area is obtained within a range between the upper limit value and the lower limit value which are determined by the luminance range determining unit (151).

摘要： An image display device which performs area-active drive suppresses occurrence of flickering that is caused when displaying dynamic images due to the emission luminance of each area being determined on the basis of a maximum or mean value of pixel luminances within that area.An emission luminance calculation section (151) divides an input image (31) into a plurality of areas, and obtains luminances upon emission of LEDs (first emission luminances) (32) in the areas. A maximum luminance position eccentricity coefficient calculation section (152) obtains maximum luminance position eccentricity coefficients (33) indicating maximum luminance positions in the areas. An emission luminance correction section (153) corrects the first emission luminances (32) on the basis of the maximum luminance position eccentricity coefficients (33) and contribution ratios (34) stored in an LED filter (156). At this time, luminances of areas positioned in the same direction as the maximum luminance positions are set to be relatively high, and luminances of areas positioned in the opposite direction to the maximum luminance positions are set to be relatively low.

摘要： In an image display device of at least one embodiment, a regional maximum detection section detects an areal maximum pixel luminance (regional maximum) on the basis of an input image. A regional mean calculation section calculates an areal mean pixel luminance (regional mean) on the basis of the input image. A data comparison section compares a control determination threshold retained in a control determination threshold storage section with the regional maximum for each area, and outputs a comparison result for that area. An LED output value calculation section sets a value corresponding to the regional maximum as an LED output value for each area with the regional maximum greater than the control determination threshold, and sets a value corresponding to the regional mean as an LED output value for each area with the regional maximum less than or equal to the control determination threshold.

摘要： Control sections of displays 11 each determine control information Pi used when area-active driving is performed individually and transmit the control information Pi to a multi-display control section 12. The multi-display control section 12 determines control information Ps for the entire device on the basis of the received pieces of control information Pi and transmits the control information Ps to the control sections of the displays 11. All the displays 11 perform area-active driving on the basis of the same control information Ps. In this way, occurrence of a luminance difference or chromaticity difference among display screens of the displays 11 is prevented and the quality of a displayed image is improved.
