Description
Technical field
The present invention relates to a kind of electronic devices, more particularly, to a kind of electronic device and its back for adjusting backlight illumination
Brightness method of adjustment.
Background technique
It is all at present aobvious to adjust according to induction environment light such as mobile phone and tablet computer with the electronic device of display panel
The backlight illumination for showing panel allows user that can see display screen in different environment.However, when object is close to the electricity
When sub-device, such as the hand of user, face etc., which is easy to block environment light, so that the electronic device is also easy to produce sentencing for mistake
It is disconnected.For example, electronic device is accordingly according to the environment to die down when the environment light that object blocks electronic device makes its light die down
Light increases its backlight illumination, and just no change has taken place at all for the environment light of the right electronic device, to be easy to that user is allowed to pierce
Eye is uncomfortable.
Summary of the invention
To solve the above problems, the object of the present invention is to provide a kind of electronics dresses for adjusting backlight illumination
It sets comprising generate the back light unit of backlight, incude the optical inductor and display unit of environment light in real time, distance-sensor is used
Object in induction preset range in real time；And control unit, for detecting the variation of environment light, when detecting optical inductor
When the environment light of induction weakens, judges whether distance-sensor senses the object in the preset range, work as distance-sensor
When sensing the object in the preset range, the backlight illumination that the back light unit adjusts the display unit is not controlled.
A kind of backlight brightness regulation method of electronic device, this method comprises the following steps: incuding environment light in real time and detects
Survey the variation of environment light；When detecting environment light decrease, judge whether to sense the object in preset range；And works as and sense
When an object in the preset range, the backlight illumination of the electronic device is not adjusted.
The present invention provides a kind of electronic device and its backlight brightness regulation method for adjusting backlight illumination, when environment light subtracts
When weak, caused by which judges whether the reason of environment light weakens is blocked as the object close to electronic device, such as
Fruit is that the electronic device does not adjust the backlight illumination of its display unit, if it is not, the electronic device increases its display unit
Backlight illumination give user's comfort to reach very accurate adjustment.
Detailed description of the invention

Fig. 2 is the method flow diagram of the electronic device adjustment backlight illumination of Fig. 1.
Wherein: 1, electronic device, 10, optical inductor, 20, distance-sensor, 30, control unit, 40, storage unit, 42,
Backlighting parameters table, 50, back light unit, 60, display unit.
Specific embodiment
The present invention that the following detailed description will be further explained with reference to the above drawings.
Fig. 1 is the hardware structural diagram of the electronic device of present invention adjustment backlight illumination.Adjust the electronics of backlight illumination
Device (hereinafter referred to as " electronic device ") 1 include optical inductor 10, distance-sensor 20, control unit 30, storage unit 40,
Back light unit 50 and display unit 60.The optical inductor 10 is used to incude environment light and the production around the electronic device 1 in real time
The illuminance signal of raw environment light.The distance-sensor 20 is used to incuded in real time from the object in 1 preset range of electronic device,
And when sensing the object in the preset range, inductive signal is generated.The storage unit 40 is stored with backlighting parameters table 42,
The backlighting parameters table 42 is stored with the corresponding relationship of each environment light and backlighting parameters.For example, the illumination of environment light is 5 Le gram
This, which is 50%, that is, increases the backlight illumination 50% of the display unit 60, another environment light
Illumination be 10 luxs, the corresponding backlighting parameters of environment light be 30%, that is, increase the backlight illumination of the display unit 60
30%.
Control generation backlight of the back light unit 50 for reception control unit 30 is bright come the backlight for adjusting display unit 60
Degree.The display unit 60 is for showing information.The control unit 30 is for detecting the variation that optical inductor 10 senses environment light
And when the environment light for detecting the induction of optical inductor 10 weakens, judge whether the distance-sensor 20 senses the preset range
Interior object judges whether the inductive signal for receiving the distance-sensor 20 transmission.When the distance-sensor 20 senses
When to an object in the preset range, illustrate that the reason of environment light weakens is the control unit caused by the blocking of the object
30 do not control the backlight illumination that the back light unit 50 adjusts the display unit 60, i.e., the backlight for not changing the display unit 60 is bright
Degree.
When the environment light decrease and distance-sensor 20 that detect the induction of optical inductor 10 do not sense the preset range
When interior object, illustrate that environment light is weakened really, which reads the backlighting parameters table in storage unit 40
42, and the illumination of the environment light sensed according to optical inductor 10, obtain the corresponding backlighting parameters of current environment light and according to this
Backlighting parameters control the backlight illumination that the back light unit 50 adjusts the display unit 60, that is, increase the backlight of the display unit 60
Brightness.
Fig. 2 is the method flow diagram of the electronic device adjustment backlight illumination of Fig. 1.The optical inductor 10 incudes the electricity in real time
Environment light around sub-device 1, the control unit 30 detecting optical inductor 10 sense the variation (step S210) of environment light；
When the environment light for detecting the induction of optical inductor 10 weakens, which judges whether to receive answers from distance perception
The inductive signal of device 20, that is, judge whether the distance-sensor 20 senses the object (step S220) in the preset range；Such as
The fruit distance-sensor 20 does not sense the object in the preset range, which reads in storage unit 40
Backlighting parameters table 42 obtains the corresponding backlighting parameters of current environment light and controls the back light unit 50 according to the backlighting parameters and adjusts
The backlight illumination (step S230) of the whole display unit 60；And if the distance-sensor 20 senses in the preset range
Object, the control unit 30 do not adjust the backlight illumination (step S240) of the display unit 60.
Therefore, a kind of electronic device 1 of the present invention and its backlight brightness regulation method, when environment light weakens, electronics dress
Setting the reason of 1 judgement environment light weakens is caused by being blocked as the object close to electronic device 1, if so, the electronics
Device 1 does not adjust the backlight illumination of its display unit 60, if it is not, the electronic device 1 increases the backlight of its display unit 60
Brightness gives user's comfort to reach very accurate adjustment.
Although being illustrated and described to the preferred embodiment of the present invention, high-ranking military officer those skilled in the art
Realize, a variety of different changes and improvements can be made, these are all without departing from true scope of the invention.Therefore, it is intended that this hair
Bright to be not limited to the disclosed specific embodiment for making optimal mode contemplated to realize the present invention, the present invention includes
All embodiments have in the protection scope of the appended claims.
