Abstract :
This paper describes a new type of 1280×1024 Digital Micromirror Device (DMD) with 50 MHz serial I/O ports. The DMD uses a unique shadow memory and pixel multiplexing scheme to realize a high-definition television (HDTV) single-chip integrated circuit display device. The project developed defect-tolerant techniques based on memory cell duplication with address decoding to improve the fabrication yield of large-chip-size devices. This DMD chip is fabricated using 0.8 μm single polysilicon and six-level metal CMOS process technology. A unique and optimized pixel with a pixel pitch of 17 μm is obtained as a result of the 25×21 mm2 compact chip design
