Problems solved by technology

[0007] In the prior art, the signal processor is used to detect the signal. Therefore, in the DPMS mode, the signal processor is still in a sleep state, and in order to speed up the output of the picture after the signal is detected, the microcontroller therefore keeps In the working state, so that in the above mode, the display still consumes a certain amount of power. Once the signal processor continues to detect no signal, the power consumption of the DPMS mode is very considerable

Abstract

The invention relates to a method of operating a display in a DPMS mode, which is suitable to the operation of the display finishing a working mode and entering the DPMS mode. Under the DPMS mode, if a signal processor of the display senses that a connecting interface has no signal input, the signal processor enters a power-off state and informs a microcontroller to start the sensing function to sense if the connecting interface has single input or not, when not sensing the signal input within continuous time, the microcontroller enters a sleep state so as to achieve the purpose of saving electricity for the display.

Description

technical field [0001] The invention relates to a method for reducing display power consumption, especially a method for reducing display power consumption in DPMS mode. Background technique [0002] At present, the display power saving function usually follows the "Energy Star" specification of the US Environmental Protection Agency and the "Display Power Management Standard (DPMS; Display Power Management Standard)" developed by the International Video Electronics Standards Association (VESA; ManagementStandard)" to qualify. Among them, the Display Power Management Standard (DPMS) provides a display power management function. When the display does not have any input signal, this function will protect the screen and enter a power saving mode to reduce the power consumed by the display. [0003] General display power management is divided into four modes: normal (Normal), standby (Standby), DPMS and off (Off) mode. As shown in Table 1, in these four modes, the signal proce...
