摘要： PROBLEM TO BE SOLVED: To provide the driving method of a liquid crystal display apparatus, such as a liquid crystal display apparatus of a vertical alignment mode and a normally black mode, for driving the liquid crystal display apparatus at high speed, while preventing degradation of a display image, even when areas in which response speeds are different from each other coexist in a pixel, and to provide the driving apparatus of the liquid crystal display apparatus and the program thereof. SOLUTION: In the liquid crystal display apparatus in which the plurality of areas in which response speeds are greatly different from each other coexist in the pixel, a gradation does not reach a desired value over several frames or excessive brightness occurs, no matter what a degree the facilitation of gradation transition may be set. A first replacement process section 42 replaces the image data of a current frame with a first gradation C1, when a gradation transition from the precedent frame to a current frame corresponds to the above gradation transition. A second replacement process section 44 replaces the image data of the current frame with a second value, when a gradation transition from a pre-precedent frame to the precedent frame corresponds to the above gradation transition. The first value C1 is set to a value causing the pixel to respond at fully high speed without the occurrence of the excessive brightness. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problems with the conventional color compensation technology that, as a result of color compensation, the upper limit values of saturation and luminance of a certain component are exceeded and the conduction of the desired color compensation is heretofore not possible in some cases. SOLUTION: The color display device determines a size relationship between three components of an input color image signal in terms of their gradation levels, and carries out a different calculation for each input color image signal depending on which of six patterns of the size relationship that the input color image signal belongs to. Further, the color display device carries out the calculation for each of the two components excluding a component with a smallest gradation level of the three components, by using variables that vary depending on the sizes of respective gradation levels of the three components.

摘要： PROBLEM TO BE SOLVED: To provide a display device with which excess brightness can be suppressed. SOLUTION: A control section 15 divides a single frame so that a ratio of a period corresponding to a latter sub-frame and a period corresponding to a former sub-frame ranges from 1:3 to 1:7. A divisional point of the frame is a point which allows each of the latter sub-frame and the former sub-frame to minimize a difference between an actual brightness and an expected brightness. In a normal hold display, the difference between the actual brightness and the expected brightness is largest in a point where the frame is divided to 1:3 to 1:7. The frame may thus be divided at the point where the difference is largest in the normal hold display, so that it is possible to minimize the difference at this point. On this account, it is possible to reduce the difference in a single frame substantially by half as compared with an arrangement for carrying out the normal hold display, and thereby suppress the excess brightness caused by the difference.
