Jagged edge compensator for staggered pixel layouts of a spatial light modulator |
摘要 |
A graphics data unit (17) for a digital television receiver (10) that uses a spatial light modulator (16). The graphics data unit (17) has a graphics processor (22), which offloads graphics processing tasks, such as for closed captioning and on-screen display, from a main processor (14). The graphics data unit (17) also has a character memory (24), which stores fonts for closed caption and on-screen display characters. A read-only memory (22a) stores graphics primitives. The character fonts and the graphics primitives may be adapted to compensate for staggered pixel layouts of the spatial light modulator (16).
