Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The adjusting method of brightness provided in an embodiment of the present invention is applied to terminal, and the terminal includes smart phone, plate
Computer, intelligent wearable device, digital audio & video players, electronic reader, handheld game machine and vehicle electronic device etc. are electric
Sub- equipment.In the embodiment of the present invention, the display screen of the terminal configuration is OLED display screen, and OLED display screen is one kind by organic
The display screen that luminescent material is constituted, luminous organic material therein can issue colored light when being powered.
Fig. 1 is a kind of flow diagram of the detection method of display screen in the embodiment of the present invention, and this method is applied to terminal,
Terminal is configured with display screen, and the display area in display screen is provided with temperature sensor.Display in the present embodiment as shown in the figure
The process of the detection method of screen may include:
S101, in go out shield state when, the display area in the display screen is detected by the temperature sensor
First temperature value.
Wherein, the screen state of going out refers to that terminal extinguishes display screen and do not show the state of any content, for example, terminal to
When machine, or during shutdown can be in screen state of going out.Opposite, the bright screen state refers to that the display screen of terminal shows content
When state.
Terminal in go out shield state when, the current institute of terminal is equivalent to by the first temperature value that temperature sensor detects
Locate the temperature of environment.For terminal out of go out period of the screen state into bright screen state, terminal can periodically pass through temperature
Sensor detect display screen in display area temperature value, then using the average value of the temperature value detected during this period of time as
First temperature value.Alternatively, terminal detects the temperature value of the display area in display screen, will test when entrance goes out and shields state
The temperature value as the first temperature value.
S102 detects the display area in the display screen by the temperature sensor after bright screen state
Second temperature value.
For terminal after bright screen state, the second temperature value detected by temperature sensor is equivalent to the current institute of terminal
Locate the sum of temperature and the heating temperature of luminous organic material of environment.
Optionally, for terminal after entering bright screen state from screen state of going out, terminal can first show a preset standard figure
Piece, such as pure color picture, then the temperature that display area is tended towards stability within a preset period of time in display screen is detected by temperature sensor
Angle value, the temperature value that will test is as second temperature value.Due to, showing different pictures, the temperature of display area is different, and
Show that preset standard picture can improve detection accuracy to avoid because showing picture bring detection error.
S103, judges whether the second temperature value and the difference of first temperature value are greater than preset threshold value, if so,
Then determine that aging occurs for the display screen.
Wherein, the preset temperature threshold, which can be, is preset by device manufacturer and is stored in terminal.It is specific real
During now, device manufacturer detects calorific capacity when its display screen shows preset standard picture before terminal factory, and should
The corresponding temperature value of calorific capacity is stored in terminal as preset temperature threshold.
Since internal resistance increases after the luminous organic material consumption in display screen, fever is caused to increase, therefore, display is same
Picture, the temperature value of the display screen after aging are then higher than the temperature value of the display screen before aging.Therefore, if second temperature value and institute
The difference for stating the first temperature value is greater than preset threshold value, it is determined that aging occurs for the display screen.
Further, terminal reduces the light emission luminance of display screen after determining that aging occurs for display screen.Reduce display screen
Light emission luminance can slow down the consumption of luminescent material, to slow down aging speed.
Assuming that minimum adjustable brightness unit is a, then the brightness of reduction can be set as 2a, 4a, 8a, etc..It reduces
By taking 2a as an example, the light emission luminance of display screen can be reduced 2a after determining that aging occurs for display screen by terminal for brightness.
Optionally, the specific implementation for reducing the light emission luminance of display screen can be the driving voltage for reducing display area
And/or driving current.
It is again optional, before terminal reduces the light emission luminance of display screen, it need to determine the brightness degree that display screen is presently in
Lower than predetermined luminance grade.
Wherein, the predetermined luminance grade can be preset by device manufacturer, be also possible to be set in advance by user
Fixed, it being not construed as limiting here, but in principle, the corresponding display brightness of predetermined luminance grade is lower, such as: assuming that display screen is most
Big brightness degree is 100%, and predetermined luminance grade can be set to 30%.The reason is that, the brightness degree locating for the display screen compared with
When low, the brightness for suitably reducing target unit display area not will cause apparent visual impact.
In the embodiment of the present invention, the display area in the display screen of terminal is provided with temperature sensor, and terminal is first being in
It goes out and detects the first temperature value of display area when shielding state by temperature sensor, then passing through temperature after bright screen state
The second temperature value of sensor detection display area is spent, is then greater than in the difference for determining second temperature value and the first temperature value pre-
If threshold value when determine display screen occur aging, so as to realize the ageing management to display screen, in addition, due to the first temperature
Value is equivalent to environment temperature, therefore second temperature value and the difference of the first temperature value are equivalent to the fever of luminescent material in display screen
Temperature determines whether display occurs aging according to the difference, can exclude the influence of environment temperature, improve accuracy.
Fig. 2 is the flow diagram of the detection method of another display screen in the embodiment of the present invention, and this method is applied to eventually

It can not show the picture of same brightness.Display screen is divided into multiple display areas, each display area passes through independent temperature
Sensor detects its temperature, improves the accuracy of temperature value.
S202 is shown after bright screen state by the corresponding each unit of detection of each temperature sensor
Show the second temperature value in region.
Specifically, terminal is after entering bright screen state from screen state of going out, terminal can first show a preset standard figure
Piece, such as pure color picture, then tended within a preset period of time by the corresponding each unit display area of detection of each temperature sensor
Stable temperature value, the temperature value that will test is as second temperature value.
S203 determines that its second temperature value is greater than the unit display area of preset threshold value with the difference of its first temperature value
Aging occurs.
S204 determines that the brightness degree that the display screen is presently in is lower than predetermined luminance grade.
S205 reduces the light emission luminance that the unit display area of aging occurs.
In the embodiment of the present invention, the display screen of terminal is divided into multiple unit display areas in advance, and each unit is shown
Region is provided with corresponding temperature sensor, and it is each that terminal first passes through the corresponding detection of each temperature sensor when in going out and shielding state
First temperature value of a unit display area, then each by the corresponding detection of each temperature sensor after bright screen state
Then it is preset to determine that the difference of its second temperature value and its first temperature value is greater than for the second temperature value of a unit display area
Aging occurs for the unit display area of threshold value, so as to realize the ageing management to display screen, in addition, due to the first temperature value
It is equivalent to environment temperature, therefore second temperature value and the difference of the first temperature value are equivalent to the fever temperature of luminescent material in display screen
Degree determines whether display occurs aging according to the difference, can exclude the influence of environment temperature, improve accuracy.
