Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The control method of the display screen that the embodiment of the present invention provides is applied to terminal, and described terminal includes the electronic equipments such as smart mobile phone, panel computer, intelligence wearable device, digital audio & video players, electronic reader, handheld game machine and vehicle electronic device.In the embodiment of the present invention, the display screen of described terminal configuration is OLED display screen, and OLED display screen is a kind of display screen being made up of luminous organic material, and luminous organic material therein can send colored light when energising.It is pointed out that depletion rate is more slow owing to the luminosity of luminous organic material is more little, therefore can pass through to reduce the brightness of display screen, reduce the depletion rate of luminous organic material, and then it is aging to slow down display screen.

S101, by the ambient brightness that the detection of described luminance sensor is extraneous.
Wherein, luminance sensor can be arranged on the front of display screen, to gather just environment light to display screen, and then the ambient brightness in the external world detected.
S102, it is determined that current preset difference value brightness, described preset difference value brightness is periodically to adjust.
Wherein, preset difference value brightness can be preset by equipment vendors and be saved in terminal before dispatching from the factory, and terminal can periodically adjust this preset difference value brightness in later stage use procedure.Preferably, the adjustment mode of terminal can be: every default unit period, increases preset difference value brightness.Such as: assuming that initial preset difference value brightness is X, default unit period is 1 month, then preset difference value brightness every 1 month, can be increased 1%X by terminal.
As the optional embodiment of one, terminal periodic adjusts the mode of preset difference value brightness can consult the content described by FIG. 2 below, is not first developed in details in explanation here.
Concrete, terminal determines the unit period being presently in, and inquires about the preset difference value brightness that current unit period is corresponding.Such as: assume that terminal has 15 months 09 days so far from first activation use, initial preset difference value brightness is X, default unit period is 1 month, being adjusted to of each unit period increases 1%X, so terminal determines that the unit period being presently in is the 16th unit period, it is possible to learn that preset difference value brightness corresponding to the 16th unit period is 115%X (=X+1%X*15).
S103, the brightness of display screen according to the ambient brightness in the described external world and described current preset difference value brightness regulation, to keep the brightness of described display screen to differ described current preset difference value brightness with the ambient brightness in the described external world.
Such as: assume that extraneous ambient brightness is Y, the preset difference value brightness determined is 115%X, then the brightness of display screen is adjusted to (Y-115%X) by terminal, further, assume that the ambient brightness in the external world becomes Z, then the brightness of display screen is adjusted to (Z-115%X) by terminal.
