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 carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
The control method of brightness that the embodiment of the present invention provides is applied to terminal, described terminal include smart mobile phone,
Panel computer, intelligence wearable device, digital audio & video players, electronic reader, handheld game machine and
The electronic equipments such as vehicle electronic device.In the embodiment of the present invention, the display screen of described terminal configuration is OLED
Display screen, OLED display screen is a kind of display screen being made up of luminous organic material, organic light emission material therein
Material can send colored light when energising.
Fig. 1 is the schematic flow sheet of the detection method of a kind of display screen in the embodiment of the present invention, and the method is applied
In terminal, terminal is configured with display screen, and the viewing area in display screen is provided with temperature sensor.As schemed
Show that the flow process of the detection method of the display screen in the present embodiment may include that
S101, be in go out screen state time, detected the display in described display screen by described temperature sensor
First temperature value in region.
Wherein, screen state of going out described in refers to that terminal is extinguished display screen and do not shown the state of any content, the most eventually
End is when standby, or all can be in, when shutdown, screen state of going out.Contrary, described bright screen state refers to end
The display screen of end shows state during content.
Terminal be in go out screen state time, the first temperature value detected by temperature sensor is equivalent to terminal
It is presently in the temperature of environment.Terminal is within the time period that screen state of going out enters bright screen state, and terminal is permissible
Periodically by the temperature value of viewing area in temperature sensor detection display screen, then will be within this time period
The meansigma methods of the temperature value detected is as the first temperature value.Or, terminal, when screen state is gone out in entrance, is examined
Survey the temperature value of viewing area in display screen, using this temperature value of detecting as the first temperature value.
S102, after being in bright screen state, detects showing in described display screen by described temperature sensor
Show second temperature value in region.
Terminal is after being in bright screen state, and the second temperature value detected by temperature sensor is equivalent to terminal
It is presently in the temperature of environment and the heating temp sum of luminous organic material.
Optionally, terminal is after entering bright screen state from screen state of going out, and terminal can first show that one is preset
Normal pictures, such as pure color picture, then by viewing area in temperature sensor detection display screen at Preset Time
The temperature value tended towards stability in Duan, using the temperature value that detects as the second temperature value.Due to, display difference
Picture, the temperature of viewing area is different, and shows that preset standard picture can be avoided because display picture brings
Detection error, improve accuracy of detection.
S103, it is judged that whether described second temperature value is more than the threshold value preset with the difference of described first temperature value,
If, it is determined that described display screen occurs aging.
Wherein, described default temperature threshold can be preset by equipment vendors and be saved in terminal.
During implementing, when equipment vendors detected its display screen display preset standard picture before terminal is dispatched from the factory
Calorific capacity, and temperature value corresponding for this calorific capacity is saved in terminal as preset temperature threshold value.
After consuming due to the luminous organic material in display screen, internal resistance increases, and causes heating to increase, therefore, aobvious
Show same picture, aging after the temperature value of display screen then higher than the temperature value of the display screen before aging.Cause
This, if the difference of the second temperature value and described first temperature value is more than the threshold value preset, it is determined that described display
Screen occurs aging.
Further, terminal, after determining that display screen generation is aging, reduces the luminosity of display screen.Fall
The luminosity of low display screen can slow down the consumption of luminescent material, thus slows down aging speed.
Assume that minimum adjustable brightness unit is a, then can set the brightness of reduction as 2a, 4a, 8a, etc..
The brightness reduced is as a example by 2a, and terminal, can be by the luminescence of display screen after determining that display screen generation is aging
Luminance-reduction 2a.
Optionally, the specific implementation of the luminosity reducing display screen can be to reduce driving of viewing area
Galvanic electricity pressure and/or driving electric current.
Optional again, before terminal reduces the luminosity of display screen, need to determine that display screen is presently in bright
Degree grade is less than predetermined luminance grade.
Wherein, described predetermined luminance grade can be set in advance by equipment vendors, it is also possible to is by user
Set in advance, it is not construed as limiting here, but in principle, display brightness corresponding to predetermined luminance grade is relatively low,
Such as: the high-high brightness grade assuming display screen is 100%, and predetermined luminance grade can be set to 30%.Reason
It is, when the brightness degree residing for display screen is relatively low, suitably reduces the brightness of target unit viewing area
Obvious visual impact can't be caused.

Be in go out screen state time by temperature sensor detection viewing area the first temperature value, then be in bright
By the second temperature value of temperature sensor detection viewing area after screen state, then judging the second temperature
It is aging that value determines when being more than, with the difference of the first temperature value, the threshold value preset that display screen occurs, such that it is able to realize
Ageing management to display screen, further, since the first temperature value is equivalent to ambient temperature, therefore the second temperature
Value is equivalent to the heating temp of luminescent material in display screen with the difference of the first temperature value, judges according to this difference
Display whether to occur aging, the impact of ambient temperature can be got rid of, improve accuracy.
Fig. 2 is the schematic flow sheet of the detection method of another kind of display screen in the embodiment of the present invention, and the method should

Temperature value occurs aging with the difference of its first temperature value more than the unit viewing area of the threshold value preset, thus
The ageing management to display screen can be realized, further, since the first temperature value is equivalent to ambient temperature, therefore
The difference of the second temperature value and the first temperature value is equivalent to the heating temp of luminescent material in display screen, according to this
Difference judges to display whether to occur aging, can get rid of the impact of ambient temperature, improve accuracy.
