20100026709 | METHODS AND SYSTEMS FOR SUB-PIXEL RENDERING WITH GAMMA ADJUSTMENT - Sub-pixel rendering with gamma adjustment allows the luminance of the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel. For each of a subset of input sampled data indicating a region of an input image, a gamma-adjusted data value is generated for each input image data value in the subset using a local average of at least two input image data values. A sub-pixel rendering operation uses the subset of gamma-adjusted data values and the subset of input image data values to produce an output data value for each sub-pixel element on the display panel. A plurality of output data values collectively indicates an output image. The gamma adjustment allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may improve image contrast in high spatial frequency portions of an image. | 02-04-2010 |
20100127267 | ALTERNATIVE THIN FILM TRANSISTORS FOR LIQUID CRYSTAL DISPLAYS - Alternative thin film transistors for liquid crystal displays are disclosed. The alternative transistors can be used for panels of displays such as liquid crystal displays (LCDs), especially those having alternative pixel arrangements. These transistors can be oriented on a panel of an LCD using different, non-traditional configurations, while addressing misalignment and parasitic capacitance. | 05-27-2010 |
20100149208 | CONVERSION OF A SUB-PIXEL FORMAT DATA TO ANOTHER SUB-PIXEL DATA FORMAT - A method of determining implied sample areas for each data point of each color in a source pixel data specified in a first sub-pixel format is used for sub-pixel rendering an image on a display specified in a second sub-pixel format. Each of the first and second sub-pixel formats comprises a plurality of colored sub-pixels. The method comprises determining a geometric center of each colored sub-pixel of the first format to define a sampling point; and defining each implied sample area by forming lines that are substantially equidistant between the sampling point of one colored sub-pixel and the sampling point of another neighboring same color colored sub-pixel. A similar technique may be used for determining resample areas for computing color values for rendering an image specified in a first sub-pixel format on a display substantially comprising a plurality of colored sub-pixels arranged in a second sub-pixel format. | 06-17-2010 |
20100164978 | FOUR COLOR ARRANGEMENTS OF EMITTERS FOR SUBPIXEL RENDERING - Novel three-color and four-color subpixel arrangements and architectures for display and the like are herein disclosed. Novel techniques for subpixel rendering on the above subpixel arrangements are also herein disclosed. | 07-01-2010 |
20100277498 | MULTIPRIMARY COLOR SUB-PIXEL RENDERING WITH METAMERIC FILTERING - Systems and methods of rendering image data to multiprimary displays that adjusts image data across metamers are herein disclosed. The metamer filtering may be based upon input image content and may optimize sub-pixel values to improve image rendering accuracy or perception. The optimizations may be made according to many possible desired effects. One embodiment comprises a display system comprising: a display, said display capable of selecting from a set of image data values, said set comprising at least one metamer; an input image data unit; a spatial frequency detection unit, said spatial frequency detection unit extracting a spatial frequency characteristic from said input image data; and a selection unit, said unit selecting image data from said metamer according to said spatial frequency characteristic. | 11-04-2010 |

20110157217 | METHODS AND SYSTEMS FOR SUB-PIXEL RENDERING WITH GAMMA ADJUSTMENT - Sub-pixel rendering with gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may be optimized for the gamma transfer curve of a display device in order to improve response time, dot inversion balance, and contrast. | 06-30-2011 |
