no. 1 example

[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.

[0043] Please refer to Figure 4 , the power saving device of the AMOLED display screen of this embodiment includes: a power saving task unit 100 for determining the display position and display resolution of a part of the display area in the AMOLED display screen; Display position and display resolution, adjust the scan signal output of the AMOLED display screen, and / or the data signal output, to fit the part of the display area.

[0044] Such as Figure 5 As shown, it includes: scanning signal lines for providing scanning signals, data signal lines for providing data signals, power lines for supplying power supply voltages, driving transistors, switching transistors, storage capacitors and organic light emitting diodes (OLEDs).

[0045] Preferably, the panel includes a plurality of scanning signal lines arranged in the vertical direction, a plurality of emission control signal lines, and a plurality of emission control signal lines; a plurality of data signal lines arranged...

Abstract

The invention discloses an electricity-saving method and an electricity-saving method device of an AMOLED (Active Matrix / Organic Light Emitting Diode) display screen, and a terminal system. The method comprises the following steps of determining a display position and display resolution of a part of display area in the AMOLED display screen; according to the display position and the display resolution, adjusting scanning signal output and / or data signal output of the AMOLED display screen so as to adapt to the part of display area. The method and the device have the advantages that 1, operation is simple, the aim of adapting to the display position and the display resolution of the part of display area is fulfilled by adjusting the scanning signal output and / or data signal output of the AMOLED display screen, and the display forms are variable; 2, electricity is greatly saved, due to the fact that the AMOLED display screen is not provided with a backlight light source, and except a driving display part, the other parts of the whole screen are in a closed state, the electricity consumption of the AMOLED display screen is effectively reduced, and the battery cruising ability of the terminal system is also increased.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a power saving method and device for an AMOLED display screen, and a terminal system. Background technique [0002] AMOLED (Active Matrix / Organic Light Emitting Diode) is an active matrix organic light-emitting diode. The principle of light emission is: use ITO transparent electrodes and metal electrodes as the anode and cathode of the device, respectively, and drive electrons and holes from the cathode under a certain voltage. And the anode is injected into the electron transport layer and the hole transport layer, and the electrons and holes migrate to the light-emitting layer through the electron transport layer and the hole transport layer respectively, and meet in the light-emitting layer to form excitons and excite the light-emitting molecules. [0003] At present, AMOLED has been widely used in mobile devices. Compared with traditional LCD, it has ...
