20080288818 | Method and System for Protecting Information between a Master Terminal and a Slave Terminal - In an application system of a liquid crystal display, for protecting transmissions between a master terminal and a slave terminal, effects caused by an unstable power source of the slave terminal have to be reduced to a lowest degree. When the application system is reset or under normal operations with the power source having a suddenly-decreased or suddenly-unstable voltage level, the transmission between the master terminal and the slave terminal have to be terminated, and related data of the terminated transmission is temporarily stored. When the voltage of the slave terminal is confirmed to reach to a stable voltage over a predetermined duration, the transmission may be restored by the stored data. | 11-20-2008 |
