[0026] The principle of the present invention is: AMOLED display has three drivers, which are respectively Data driver, Scan driver, and Vdd driver. When the three drivers are all active, a single pixel of the display is lit. Vdd is a common electrode and cannot be changed, but Data driver and Scan driver It can be changed by the signal, so it only needs to give the relevant display position and display resolution instructions, which can realize power-saving display.
[0027] Please refer to figure 1 , The power saving method of the AMOLED display screen of the present invention comprises: S100, determining the display position and display resolution of a part of the display area in the AMOLED display screen; S200, adjusting the scanning signal of the AMOLED display screen according to the display position and display resolution output, and / or data signal output to fit the portion of the display area.
[0028] Preferably, said determining the display position and display reso...
