Abstract:
A method of displaying a display power management signaling (DPMS) using an on screen display integrated circuit (OSD IC) in a display device comprising the steps of:determining whether a sync signal is input or not;storing, in a memory of a microcomputer, a current DPMS state corresponding to the sync signal which is input; anddriving said OSD IC in response to an OSD drive signal output from an OSD drive output port of said microcomputer to display a message on a screen of said display device during a predetermined time after a user key on said display device is activated, said message being indicative of the stored current DPMS state; said driving step comprising:detecting an input from said user key;adjusting a DPMS output port of said microcomputer to a normal mode, when the input of said user key is detected, for enabling the message indicative of the current DPMS mode to be displayed during the predetermined time; andrestoring the DPMS output port to the stored DPMS state after the predetermined time period has elapsed.
