Abstract

The invention discloses a method and device for self-adaptive energy-saving control of LED display screen energy consumption. The method obtains the information currently sent to the display screen by external equipment in real time, performs logical calculation on the information according to predetermined algorithm rules, and outputs the dynamic calculation value of the display screen. , divide the running process of the external device into N task states in advance, set a unique task state code for each task state, bind the dynamic calculation value of the display screen with the corresponding task state code, and the bound task state code corresponds to It is associated with the preset energy consumption level of the display screen, generates corresponding energy-saving control instructions according to the energy consumption level of the display screen, and adjusts the input power of the display screen.

Description

technical field [0001] The invention relates to the technical field of energy saving of LED display screens, in particular to an adaptive energy saving control method and device for LED display screen energy consumption. Background technique [0002] At present, there are two main methods for controlling the display energy consumption of LED displays in the market. Among them, most of them adopt the method of regularly adjusting the display energy consumption. And preset the energy consumption of the display screen corresponding to the light intensity to realize the automatic regulation of the energy consumption of the display screen, so as to achieve the purpose of energy saving and consumption reduction of the display screen. [0003] As for the regulation method of regularly regulating the energy consumption of the display screen, when the energy consumption of the display screen cannot change with the arrival of the preset timing time, this regulation method has a functi...
