Abstract
The invention discloses an energy conservation method of a display terminal, which comprises the following steps of 1 a host machine initiatively detects a registry in time, reads key values in the registry, and judges whether the host machine operates a screen saver or not according to screen saver index signals; 2 the host machine sends video communication processor (VCP) instruments including the control display terminal states to a micro control unit of the display terminal through a direct digital control/corporate identity (DDC/CI) channel when the host machine is judged to start to operate or stop operating the screen saver; and 3 the micro control unit of the display terminal executes the VCP instruments to control states of the display terminal. The energy conservation method of the display terminal enables the host machine and the display terminal to be capable of initiatively and mutually communicating when the host machine enters the screen saver, thereby enabling the states of the display terminal to automatically change along switching of the screen saver of the host machine and saving energy consumption.
Description
Technical field
The present invention relates to a kind of when main frame gets into screen protection program, the display terminal power-economizing method that the duty of display terminal is controlled.
Background technology
At present, when operating personnel did not operate computer for a long time, computer (main frame) got into screen protection program.At this moment generally there is two states in display terminal:
State 1: computer display screen is protected picture, and display terminal still is operated in normal state.At this moment, display terminal still is operated under the high power consumption state, and energy dissipation is serious.
State 2: computer cuts off the signal that exports display terminal to, and whether display terminal exists input signal to judge whether to get into power save mode through MCU (Micro Control Unit/ micro-control unit) detecting.
Still do not have at present main frame to pass through application program and the intercommunication mutually initiatively of display terminal micro-control unit, thereby make the technology of the state of display terminal with the automatic change of switch of main frame screen protection program.
Summary of the invention

Step 2: when the judgement main frame brought into operation or finishes to move screen protection program, main frame sent the VCP instruction that comprises control display terminal state through the DDC/CI passage to the micro-control unit of display terminal;
Step 3: thus the micro-control unit of display terminal is carried out the state of this VCP instruction control display terminal.
In the step 2 of the present invention, when judging that main frame brings into operation screen protection program, main frame sends the VCP instruction that comprises control display terminal entering power save mode through the DDC/CI passage to the micro-control unit of display terminal.
The VCP instruction that comprises control display terminal entering power save mode of the present invention comprises reduction display terminal backlight illumination, or the adjustment contrast, or gets into the display terminal sleep state, or entering display terminal off-mode.
In the step 2 of the present invention, when judging that main frame finishes the operation screen protection program, main frame comprises the VCP instruction that the control display terminal recovers normal operation mode through the DDC/CI passage to the micro-control unit transmission of display terminal.
DDC/CI passage of the present invention is the video data control channel that connects main frame video card and each video interface of display terminal.
Main frame is to the active detecting real-time of registration table and to send the VCP instruction that comprises control display terminal state to the micro-control unit of display terminal be to carry out through moving preset application program.
Main frame in the detecting real-time of registration table and the step 2 is sent the VCP instruction through the DDC/CI passage to the micro-control unit of display terminal can be to realize through carrying out preset application program to main frame in the step 1 of the present invention, and concrete implementation method can adopt any prior art and corresponding programming language to realize.
VCP instruction of the present invention can be write or rewrite by prior art as required.
Concrete, adopt above method, host application program is the detecting real-time registration table initiatively, reads the key assignments in the registration table, and whether the program of answering according to key-value pair is moved and is judged whether main frame moves screen protection program; When judging that main frame brings into operation screen protection program; Main frame sends the VCP instruction that comprises control display terminal entering power save mode through the DDC/CI passage in the signal wire that connects main frame video card and display terminal video interface to the micro-control unit of display terminal; As reduce the display terminal backlight illumination; Or the adjustment contrast, or get into the display terminal sleep state, or get into VCP instruction such as display terminal off-mode; Thereby the micro-control unit of display terminal is carried out this VCP instruction control display terminal and is got into power save mode;
After getting into power save mode; When judging that main frame finishes the operation screen protection program; The VCP instruction that main frame sends control display terminal recovery normal operation mode through the DDC/CI passage to the micro-control unit of display terminal, thus the micro-control unit of display terminal is carried out this VCP instruction control display terminal recovery normal operation mode.Entire work process is by moving in circles with upper type.
Power-economizing method of the present invention makes when main frame gets into screen protection, the intercommunication mutually that main frame and display terminal can be initiatively, thus the state that makes display terminal changes the saving energy resource consumption automatically with the switch of main frame screen protection program.
