摘要： An apparatus and method thereof to improve a response speed of an LCD includes a noise rejection unit and a comparator. The noise rejection unit rejects noise in current digital image data and previous digital image data at a same pixel position as in the current digital image data. The comparator compares the current digital image data and the previous digital image data of which noises are rejected within a reference value, changes the current digital image data based on a comparison result, and outputs a result indicative thereof.

摘要： A method of adjusting a displaying state of a display apparatus includes determining a reference color temperature and a reference Δu′v′, determining setting color temperatures corresponding to gradations of a gray level according to the reference color temperature to make color temperature differences between adjacent gradations of the gray level be within a predetermined color temperature range, measuring coordinates according to the gradations within a gray area formed by the gray level and displayable in the display apparatus on a predetermined color coordinates system corresponding to the reference Δu′v′ and the setting color temperatures corresponding to the gradations, and setting the coordinates corresponding to the gradations measured about each gradation of the gray level of the display apparatus. Thus the method of adjusting a displaying state of a display apparatus varies a color sensation to have directionality and linearity between gradations of a gray level, thereby improving color representation.

摘要： A high definition image projector is provided for modulating light using an acousto-optic tunable filter according to image signals and projecting the modulated light on a screen. An image is obtained by modulating a light beam by pixel units according to the image to be displayed and directly projecting the modulated light beam on the screen in corresponding pixel units. High quality images can thus be displayed on a large screen. By adopting a high-output light source, a high luminance image can be obtained.
