摘要： A two-dimensional encoder stores data on a holographic memory. The encoder encodes data of k bits (where k is an integer and k≧3) into n pixels arranged two-dimensionally (where n is an integer and n≧6). The encoder includes a first processing section 31 for classifying the n pixels into first and second groups of subblocks 11 and 12 using k1 bits out of the data of k bits (where k1 is an integer and k1≧1). Each of the subblocks 11 in the first group consists of m pixels (where m is an integer and m≧2), and the number of the subblocks 11 forming the first group is s1 (where s1 is an integer and s1≧2). Each of the subblocks 12 in the second group also consists of m pixels, and the number of the subblocks 12 forming the second group is s2 (where s2 is an integer and s2≧1). The encoder further includes a second processing section 32 for turning ON p pixels (where p is an integer and 1≦p≦m/2) out of the m pixels forming each subblock 11 in the first group and turning OFF all of the m pixels forming each subblock 12 in the second group using the other k2 bits of the data of k bits (where k2=k−k1).

摘要： Disclosed is a liquid crystal display device, which is capable of reducing a required response speed and increasing a pixel aperture ratio, as compared with a field sequential driving scheme. A unit pixel of a liquid crystal display panel is made up of a first sub-pixel adapted to allow only any two of red, green and blue lights to pass therethrough, and a second sub-pixel adapted to allow only a remaining one of the red, green and blue lights to pass therethrough, wherein one frame of image is time-divided into n pieces (wherein n is an integer of two or more), and respective image information about the two lights are applied to the first sub-pixel during every duration of the 1/n frame, while applying image information about the remaining one light to the second sub-pixel during a duration of the one frame of image. Further, the respective two lights are emitted during every duration of the 1/n frame in synchronization with applying the respective image information about the two lights, while continuously emitting the remaining one light during the duration of the one frame of image.
