Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of terminal display screen control method, and reference picture 1, Fig. 1 is terminal display screen controlling party of the present invention
The schematic flow sheet of method first embodiment.
In the present embodiment, the terminal display screen control method comprises the following steps：
Step S10, using the ultraviolet index of UV sensor detection terminal local environment；
When user carries out the operation such as web page browsing, communication chat using terminals such as smart mobile phone, PAD (tablet personal computer),
If the light of current environment is too strong, user can not just see the content of terminal display screen clearly, and the use to user is made troubles.In order to
Solve this problem, in the present embodiment, UV sensor is pre-set in terminal, such as flat where terminal display screen
Face sets UV sensor, and UV sensor can measure the ultraviolet index of current environment.Therefore, in the present embodiment,
When user's using terminal, by using the ultraviolet index of UV sensor detection terminal local environment, terminal obtains purple
The ultraviolet index for the terminal local environment that outside line sensor detects.
Step S20, the size of the ultraviolet index and default ultraviolet index threshold value；
Step S30, when the ultraviolet index is more than the default ultraviolet index threshold value, increases the terminal and show
The contrast of screen.
In the present embodiment, in order to there is a differentiation to the power of ultraviolet, a default ultraviolet index is also previously provided with
Threshold value, after the ultraviolet index of terminal local environment is detected, terminal compares the ultraviolet index and default ultraviolet index
The size of threshold value.When the ultraviolet index of terminal local environment is more than default ultraviolet index threshold value, namely explanation terminal institute
The ultraviolet of locating environment is relatively strong, light is brighter, and now, user does not see the content shown by terminal display screen probably, is
It can be easy to the user to see the content that display screen is shown clearly, the contrast of terminal display screen is adjusted, increase terminal is shown
The contrast of screen.After increase regulation is carried out to the contrast of terminal display screen, user can more clearly see display screen institute clearly
The content of display.When the ultraviolet index of terminal local environment is less than or equal to default ultraviolet index threshold value, namely explanation
The ultraviolet of terminal local environment is not strong, and light is suitable, and user can see the content that display screen is shown clearly, and now, terminal is not entered
The corresponding response processing of row.
The scheme that the present embodiment provides, terminal use the ultraviolet index of UV sensor detection terminal local environment,
Then the size of the ultraviolet index of comparison terminal local environment and default ultraviolet index threshold value, in the purple of terminal local environment
When outer linear index is more than default ultraviolet index threshold value, namely when ambient light is stronger, increase the contrast of terminal display screen,
So as to enhance the visuality of display screen so that user can more clearly see the content shown by display screen clearly, improve use
Experience at family.
Further, as shown in Fig. 2 proposing that terminal display screen control method second of the present invention is implemented based on first embodiment

, can not absolute guarantee's purple although ultraviolet index reflects the light intensity of current environment to a certain extent
Outer linear index is higher, and light intensity is stronger, therefore, in the present embodiment, in order to more accurately be carried out to terminal display screen
Regulation, terminal go back the light intensity of detection terminal local environment first.For example, optical sensor is also provided with terminal,
For example optical sensor is set in the close position of seated position set by UV sensor, optical sensor can measure current environment
Light intensity.When user's using terminal, by using the light intensity of optical sensor detection terminal local environment, terminal obtains
The light intensity for the terminal local environment that optical sensor detects.
In order to there is a differentiation to the power of light, a default light intensity threshold value is also previously provided with, when detecting end
After the light intensity for holding local environment, terminal compares the size of the light intensity and default light intensity threshold value.When residing for terminal
When the light intensity of environment is more than default light intensity threshold value, namely the light of explanation terminal local environment is stronger, now, terminal
The further ultraviolet index of detection terminal local environment.It is more than default ultraviolet in the ultraviolet index of terminal local environment
During index threshold, increase the contrast of terminal display screen.When the light intensity of terminal local environment is less than or equal to default light
During intensity threshold, namely the light of explanation terminal local environment is weaker, and user can see the content shown by terminal display screen clearly,
Now, terminal is handled without corresponding response.
Further, in order that the visuality for obtaining terminal display screen further enhances, in the ultraviolet of terminal local environment
When index is more than default ultraviolet index threshold value, contrast and the brightness of terminal display screen can be strengthened simultaneously.
Further, in the present embodiment, after the step S20, in addition to step：
When the ultraviolet index is less than or equal to the default ultraviolet index threshold value, strengthen the terminal display screen
Brightness.
In the present embodiment, to the ultraviolet index of terminal local environment compared with default ultraviolet index threshold value
Afterwards, when the ultraviolet index of terminal local environment is less than or equal to the default ultraviolet index threshold value, namely the current light of explanation
Line is stronger, but ultraviolet index is not high, and now, in order to be easy to user to see the content that display screen is shown clearly, terminal is shown
The brightness of screen is adjusted, and strengthens the brightness of terminal display screen.After the brightness to terminal display screen carries out enhancing regulation, user
The content shown by display screen can more clearly be seen clearly.
Further, the step S30 includes：
Step a, when the ultraviolet index is more than the default ultraviolet index threshold value, institute is calculated using brightness algorithm
State the present intensity of each pixel of terminal display screen；
Step b, the pixel of predetermined luminance threshold value is more than to present intensity, strengthens the present intensity of the pixel；
Step c, the pixel of the predetermined luminance threshold value is less than or equal to present intensity, weakens working as the pixel
