    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.

    摘要: In an LCD data calculation section, a base data calculation section calculates LCD data before temperature compensation based on an input image and display luminance of each area of a backlight, a scene change detection section detects a scene change point at which the amount of change of the input image increases, based on the input image, and an LUT selection and application section acquires an appropriate table corresponding to the temperature of a liquid crystal panel from a temperature compensation LUT, and applies the table at the scene change point, thereby outputting LCD data subjected to temperature compensation. Thus, temperature compensation can be performed without adversely affecting display luminances of the backlight, making it possible to correctly provide tone display without uneven luminances even in the case of area-active drive.

    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.
