GENERATION OF PATTERN DATA FREE FROM ANY OVERLAPPING OR EXCESSIVE SEPARATION OF DOT PATTERNS ADJACENT TO EACH OTHER |
摘要 |
A device is disclosed for generating pattern data for unevenness that is randomly arranged on the surface of the reflective substrate of a reflective liquid crystal display device. The number of coordinates, a basic pitch, a movable range, and a dot diameter are entered from a data entry unit. An array generation unit regularly arranges base coordinates in two dimensions in accordance with the basic pitch. Coordinate displacement unit randomly displaces within the movable range at a portion of the basic coordinates to generate a multiplicity of displaced coordinates. Pattern generation unit arranges dot patterns with the dot diameter entered at each of the displaced coordinates generated to generate pattern data. <IMAGE> |
