摘要： The cold cathode tube for illuminating pixels with light which is in accordance with an output signal has luminance which gradually increases at a rise and gradually decreases at a fall per one frame time. The cold cathode tube contains a fluorescent material of only one of three primary colors of light, and has a certain OFF period or dimming period per one frame time. Between a diffusing plate and a reflecting plate are provided partition walls for parting emitting areas, so that the illumination light of one cold cathode tube does not reach the display elements to be illuminated by the other cold cathode tubes. The emission of each display element is changed per one frame time between a normal ON state and a dim state. The cold cathode tube has two or more OFF periods within one frame time, and, luminance of the cold cathode tube is changed per one frame period. As a result, it is possible to suppress shortening of life of emitters in an illuminating section, and to relieve lowering of luminance of the emitters, and also to obtain a desirable display quality even in a fast-moving image.

摘要： A liquid crystal display of the present invention facilitates grayscale level transition from a previous frame to a current frame, in such a manner that a modulation driving process section reads out, from one look-up table, corrected image data corresponding to a combination of image data of a previous frame and image data of a current frame and then outputs this corrected image data, irrespective of the ambient temperature. Meanwhile, a temperature circuit controls a heater so as to either stop the heating by the heater when a temperature of the liquid crystal panel exceeds a threshold value which is 1° C. through 1.5° C. higher than a target temperature, or start the heating by the heater when the temperature of the liquid crystal panel goes below a threshold value which is 1° C. through 1.5° C. lower than the target temperature, the target temperature being determined in advance to be in a range between 48° C. and 63° C. In this manner, it is possible to realize a liquid crystal display which is simple in circuit arrangement but can improve a response speed while restraining the degradation of display quality to be hardly recognizable for the viewer.

摘要： An emphasis converter 52 compares the image data of the current vertical period with the image data of the previous vertical period and controls the input image data to a liquid crystal display panel 4 based on the emphasis conversion parameters stored in tables of ROMs 3a to 3c so as to achieve accelerated drive. A microcomputer 38 is able to realize stable control of selecting emphasis conversion parameters by adding hysteresis to the detected temperature from a thermistor 37 even when the detected temperature fluctuates up and down crossing the temperature threshold.

摘要： The method of driving a liquid crystal display in accordance with one embodiment of the present invention is a method of driving a liquid crystal display whereby a first liquid crystal panels produces a display from a first display signal and the second liquid crystal panel produces a display a second display signal derived from the first display signal, the first and second liquid crystal panels being stacked on top of each other. The luminance of the first liquid crystal panel is extended based on the luminance extension ratio obtained from the gray levels for dots contained in the first display signal and a logical maximum gray level of input image data. The luminance of the second liquid crystal panel which produces a display from the second display signal is lowered by the amount by which luminance is extended on the first liquid crystal panel. A liquid crystal display with high display quality is realized by restraining decrease in saturation which would otherwise become obtrusive when two liquid crystal panels are stacked.

摘要： A liquid crystal display apparatus includes a plurality of areas in which response speeds greatly different from each other coexist in a pixel. A first replacement process section replaces the image data of the desired target frame with a first gradation, when a gradation transition from a current frame to a desired target frame corresponds to the above gradation transition. A second replacement process section replaces the image data of the current frame with a second value. The first value is set to a value causing the pixel to respond at a relatively higher speed without the occurrence of the excessive brightness. Without avoiding the deterioration of the image, it is possible to drive a liquid crystal display apparatus including areas whose response speeds are different from each other coexist in the pixel, such as a liquid crystal display apparatus of vertically aligned mode and normally black mode.

摘要： In one embodiment of the present invention, in the case of dark display on sub-pixels, a sub-frame processing section is disclosed which sets video data for a sub-frame to a value falling within the range for dark display, and increases or decreases video data for a sub-frame so as to control luminance of the sub-pixels. In the case of bright display, the sub-frame processing section sets video data to a value falling within the range for bright display, and increase or decreases video data so as to control luminance of the sub-pixels. A modulation processing section corrects video data of each frame and then outputs corrected video data to the sub-frame processing section. Also, the modulation processing section predicts luminance that the sub-pixels reach at the end of the frame and then stores prediction results for correction and prediction in the subsequent frame. This realizes a display device which is brighter, has a wider range of viewing angles, restrains deteriorated image quality caused by excessive emphasis of grayscale transition, and has improved moving image quality.
