Abstract: PROBLEM TO BE SOLVED: To provide a display device of a field sequential system capable of suppressing a color breakup phenomenon. SOLUTION: The liquid crystal display device is composed of a liquid crystal panel without a color filter, and a light source section (backlight) in which a light emitting area is divided into a plurality of partial light emitting areas, and color display is enabled by partial driving. All colors are not expressed by combination of RGB, but all colors are decomposed into three elements of "a reference white component", "a complementary component" and "a prime color component". Color combination is performed in space, and light emitting amount combination is performed in time, by allocating (distributing) the white component or the complementary component in a field direction with equal distribution principle so that correlation between fields may be enlarged. Thereby, color display with almost no color breakup phenomenon is attained, even in the field sequential system without the color filter. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display capable of improving image quality of a display image when performing partial lighting operations by a light source section. SOLUTION: A flare countermeasure correction section 62 determines, based on an image signal D0, whether a condition is satisfied such that a partial display region corresponding to the partial lighting section 4 includes a low-luminance region in the periphery of a high-luminance region. When it is determined that the above condition is satisfied, the flare countermeasure correction section 62 corrects the image signal D0 in the low-luminance region in the following manner. On a condition that the partial lighting section 4 corresponding to the partial display region satisfying the condition has a luminous energy (a set luminance BLpix) determined by a backlight control section 12, the correction of the image signal D0 in the low-luminance region is performed so that the display luminance level of the low-luminance region of the partial display region results in approximately equal to the display luminance level under a maximum luminous energy (a maximum luminance BLmax) of the partial lighting section 4 corresponding to the partial display region. Then, display driving in the low-luminance region is performed based on the corrected image signal D1. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suitably display a movie raw material without irrespective of a variation in brightness in an environment. SOLUTION: A film of 24 [Hz] is inputted as an input signal T0 for example. A motion vector calculation unit (11) calculates a motion vector MV of an object included in the film. A motion vector conversion unit (12) converts the motion vector MV into a motion vector G×MV by multiplying the calculated motion vector MV by a gain G. The gain G is detected by a gain calculation unit 14 according to brightness P1 in a user environment by detecting the brightness P1 by a lightness detection unit 15. A frame compensation unit (13) generates an output signal T1 of 120 [Hz] by performing the frame compensation processing of converting or compensating for access units on the input signal T0 so that the object may move according to the motion vector G×MV which has been subjected to the conversion. The present invention is applicable to a television system. COPYRIGHT: (C)2009,JPO&INPIT
