ABSTRACT:
A method of realizing DPMS function of a display using an USB is proposed. In the DPMS mode transition performed by recognizing input states of horizontal and vertical synchronous signals, the operation state of the USB is confirmed when the DPMS mode is converted from suspend mode to power off mode. Accordingly, the transition to the power off mode is prevented when the USB is in operation, thereby protecting the USB from malfunctioning.
