摘要： In the present liquid crystal display device, an LED output value correction section (513) included in an area-active drive processing section (5) corrects LED data Dbl obtained by an LED output value calculation section (512) with reference to a luminance correction LUT (13), such that the luminance in the area from an intermediate value to near a maximum value shifts to a higher degree. Thus, even if the backlight luminance is low (typically, the mean luminance of an input image is low), contrast ratio is enhanced, thereby preventing a tone jump (insufficient luminance) at high tone levels due to an insufficient backlight luminance.

摘要： An emission luminance calculation section of an image display device divides an input image into a plurality of areas, and obtains luminances upon emission of LEDs in the areas. A maximum luminance position eccentricity coefficient calculation section obtains maximum luminance position eccentricity coefficients indicating maximum luminance positions in the areas. An emission luminance correction section corrects the first emission luminances on the basis of the maximum luminance position eccentricity coefficients and contribution ratios stored in an LED filter. 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： In at least one example embodiment, the present invention includes a liquid crystal display panel for displaying an image by virtue of having liquid crystals whose orientation changes in response to application of a voltage; a backlight unit with a built-in PWM light modulation type LED for emitting light to be supplied to the liquid crystal display panel; and a control unit for controlling the liquid crystal display panel and the backlight unit. In cases where the response speed of liquid crystal molecules is relatively high, the LED is driven at a relatively low drive frequency, whereas in cases where the response speed of the liquid crystal molecules is relatively low, the LED is driven at a relatively high drive frequency. According to the present invention, problems with image quality that tend to occur depending on the degree of tilting of the liquid crystal molecules (ghost outlines) are prevented.
