20080198185 | DISPLAY DEVICE - A signal converter to make a display module conduct an n-ply display operation divides one frame period of input display data into n subframes to obtain n-ply display data, shifts the sampling position for each n-ply display data, samples the data to convert resolution thereof, rearranges in n ways a combination of subpixels included in each pixel of output display data resultant from the sampling, and varying the sampling position and the combination of subpixels for each subframe in a cooperative fashion. | 08-21-2008 |
20080238848 | Display Device - A hold-type display device reduces the blur of a moving image and makes less conspicuous the color shift caused due to different blur positions among RGB. In the case where the relative brightness of the video data of one or two of the three primary colors RGB changes from between 0 and 0.5 inclusive for the previous frame to between 0 and 0.5 inclusive for the present frame, the video image of the one or two colors is delayed by one frame and displayed. | 10-02-2008 |
20080303758 | Display Device - High-order bits to be utilized for current-frame display data and previous-frame display data, and low-order bits to be utilized for the current-frame display data alone are stored in independently controllable memory areas. For reading the current-frame display data from a frame memory, data of the high-order bits and data of the low-order bits are read. For reading the previous-frame data, the high-order bits alone are read. Thus, since a period during which the data of the low-order bits that is not utilized for the previous-frame display data is stored in the memory is shortened, a required memory capacity can be reduced. The data transfer time can be reduced by the time required for memory read for the data of the low-order bits that is not utilized for the previous-frame display data. | 12-11-2008 |
20090060365 | IMAGE DISPLAY DEVICE, IMAGE PROCESSING CIRCUIT, AND IMAGE PROCESSING METHOD - To provide a processing method for reducing motion blur while increasing resolution. By performing a super-resolution process, a resolution-increased image is obtained from an input image in multiple frames. By performing an enlargement process, an enlarged image is obtained from the input image in one frame. A high-frequency image is obtained by subtracting the enlarged image from the resolution-increased image. A high spatial frequency-emphasized image is obtained by adding the high-frequency image to the resolution-increased image. The enlarged image and high spatial frequency-emphasized image are displayed alternately every half frame. | 03-05-2009 |
20090085856 | Display Device - An overdrive device corrects IN data by referring to a look-up table based on IN data, ODA data outputted from the look-up table, which is previous by one frame and ODB data outputted from the look-up table, which is previous by two frames. | 04-02-2009 |
20090109135 | DISPLAY APPARATUS - To reduce moving image blurring with a simple circuit while an image quality of a still image is maintained, a display apparatus emphasizes and deemphasizes a change in display data along a temporal direction based upon preceding frame data and current frame data, emphasizes and deemphasizes a change in the emphasized and deemphasized display data along a spatial direction, and displays, with respect to a portion where the display data has been changed between frames, an image in which the change in display data is emphasized along both the temporal direction and the spatial direction, and another image in which the change in display data is deemphasized along both the temporal direction and the spatial direction within one rendering frame period. | 04-30-2009 |
