Cathode ray tube display monitor - has micro controller to generate status signal to activate protection circuit when synchronisation signal frequency exceeds limit |
摘要 |
<p>The cathode ray tube display [30] receives control inputs from a drive circuit [20] that is coupled to a protection circuit [140]. The system has a microcomputer [100] that receives horizontal and vertical synchronisation signals from a central computer, eg a PC, and executes a check for a change in frequency. When the frequency exceeds a limit, a status signal generator circuit [110] outputs to the protection circuit and blocks output of the synchronisation signals.</p> |
