Open the CIPO recordAbstract From the Canadian patent
A serial-to-parallel converter circuit is constructed of a plurality of D flip-flops receiving as a clock signal, data in a single signal of serial data stored in a ROM. Each D flip-flop transmits "high" data to a next stage through a latch operation every time a piece of the data is read from the ROM. The plurality of D flip-flops converts the signal of serial data to parallel data by producing output signals as control signals. According to this arrangement a signal production circuit and a display device incorporating it become available which allow for a reduction in the capacity cost, and dimensions of the storage means and also in the wiring and substrate areas required around the …

Why it's free to use
- Filed October 11, 2000 and granted June 3, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 11, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 11, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
