In order to make the purpose of the present invention, technical scheme and beneficial effect the clearest, below in conjunction with accompanying drawing
And embodiment, the present invention is further elaborated.Should be appreciated that described herein being embodied as
Example only in order to explain the present invention, is not intended to limit the present invention.
The method that the embodiment of the present invention is provided is applicable to the touch screen under several scenes, as meeting, commander,
Exhibition and education etc..The embodiment of the present invention illustrates based on as a example by education scene, uses in education scene
It is interactive touch all-in-one, when teacher closely carries out contact action, needs relatively low brightness, to reduce
Injury to contact action person's eyes, and student watches touch screen at a distance, then need higher brightness, with
Ensure that it can be seen clear.
It is normal display brightness that user can arrange the first brightness of interactive touch all-in-one, and the second brightness is soft
Showing pattern with light, the 3rd brightness is dark display brightness.Wherein, the brightness value of the first brightness is more than second
The brightness value of brightness, the brightness value of the second brightness is more than the brightness value of the 3rd brightness.
Based on above-mentioned application scenarios, the embodiment of the present invention provides a kind of touch screen luminance regulating method, such as Fig. 1
Shown in, comprise the following steps:
Step 101, periodically detecting touch screen surrounding brightness；
Step 102, if the environment bright that the environmental light brightness that current period detects detected with the previous cycle
Degree ratio less than set threshold value, then by described touch screen brightness from the first luminance-reduction to the second brightness；Its
In, the described span setting threshold value is as (0,1)；
Step 103, in presetting the first duration, if detecting contact action, then by described touch screen brightness
From the second luminance-reduction to the 3rd brightness；A length of described touch screen brightness is dropped from the first brightness when presetting first
A period of time after as little as second brightness.
In the present embodiment, interactive touch TV integrated machine is provided with touch screen, simultaneously in interactive touch
The first detector unit is added on TV integrated machine, in order to the brightness of surrounding environment light is periodically detected,
Ambient light with detection surrounding is the most dimmed.First detector unit can be photographic head, it is possible to for visible ray
Light sensitive device, infrared light light sensitive device.Concrete, light sensitive device or photographic head may be arranged at interactive touch
The surrounding of TV integrated machine, or in surrounding arbitrarily, or any several limits in surrounding, described first
Detector unit can include multiple detection sub-unit.When described first detector unit comprises multiple detection sub-unit,
Described environmental light brightness is the meansigma methods of the environmental light brightness that the plurality of detection sub-unit detects.Interactive
Touch and also arrange touch control component, in order to be periodically detected whether user carries out touch control operation on TV integrated machine.
In a step 101, use the first detector unit to the environmental light brightness detecting around touch screen.
Concrete, when touch screen is in running order, the first detector unit presses first frequency periodically to touch
The periodically detecting of screen environmental light brightness around.It is also preferred that the left first frequency can arrange smaller, alleviate system
Resource consumption, such as, first frequency may be configured as 5Hz.
In a step 102, if the environment that detects with the previous cycle of the environmental light brightness that current period detects
The ratio of brightness less than set threshold value, then by described touch screen brightness from the first luminance-reduction to the second brightness；
Wherein, the described span setting threshold value is as (0,1).
When the first detector unit is light sensitive device, due to user near interactive touch TV integrated machine time,
Whether can produce light sensitive device and block, therefore can be changed by detection surrounding brightness is judged
Whether there is people close.Concrete, the current period environmental light brightness detected and previous cycle are detected
Environmental light brightness compares, the ring that the environmental light brightness detected when current period detected with the previous cycle
The ratio of border brightness, less than when setting threshold value, confirms to detect that touch screen surrounding brightness is dimmed.Wherein,
The described span setting threshold value is as (0,1).Such as, threshold value is set as 0.5, then when the ring detected
When the ratio of the environmental light brightness that border brightness and previous cycle detect is less than 0.5, Current ambient is i.e. described
Ambient light than front one-time detection time surrounding light secretly a lot, now confirm to detect around touch screen
Ambient brightness is dimmed, and light sensitive device is blocked, in teaching scene, it is possible to be that teacher has walked close to touch
Screen.
During it is also preferred that the left the first detector unit is photographic head, after surrounding environment light luminance-reduction being detected,
Also by face identification functions, further determine that surrounding environment light is dimmed whether because there being people close.
If the ratio of the environmental light brightness that the environmental light brightness that current period detects and previous cycle detect
Not less than set threshold value time, then prove current ambient environmental light not than front one-time detection time surrounding
Dark is a lot, it is also possible to current ambient environmental light brightens, and now confirms ring around touch screen to be detected
Border brightness is the most dimmed, then keep current state, do not do any operation.
When detecting that touch screen surrounding brightness is dimmed, by first rate by described touch screen brightness from
One luminance-reduction is to the second brightness.Owing to human eye is insensitive to brightness change time higher, therefore can be by first
Speed is set as bigger value, and from the first brightness linear, described touch screen brightness is reduced to the second brightness.
Use this kind of scheme can rapidly by luminance-reduction before teacher closely performs touch operation, and the
Two brightness are fill light pattern, i.e. the touch screen brightness of interactive touch all-in-one can guarantee that the viewing effect of student
Really.
When described ambient light is dimmed, some subelement in the first detector unit or the first detector unit is examined
The environmental light brightness measured subtracts secretly.In the present embodiment, touch screen is one from the first luminance-reduction to the second brightness
The adjustment of secondary property, i.e. when the brightness value of ambient light in brightness value and previous cycle of ambient light of current period
Ratio less than predetermined threshold value time, touch screen from the first luminance-reduction to the second brightness.If fruit ring after the adjustment
Border brightness continues dimmed, and the touch screen brightness in the present embodiment is also without the adjustment doing brightness.
In step 103, whether it is periodically detected by the second detector unit on interactive touch all-in-one
There is touch control operation, described touch screen brightness after the first luminance-reduction to the second brightness preset first
In duration, if contact action being detected, by the second speed by described touch screen brightness from the second luminance-reduction to
3rd brightness；Wherein, the second speed is less than first rate.
Specifically, when contact action having been detected, human eye is the most closely near touch screen, now
If light variable quantity is excessive, too fast, the most still human eye can be damaged.By second in the embodiment of the present invention
Speed is by described touch screen brightness from the second luminance-reduction to the 3rd brightness, and it is less that the second speed can be arranged,
And the second rate value can be set to smooth curve, to reach slowly to reduce the purpose of touch screen brightness.Alleviate
Spinning sensation when brightness adjustment is too fast caused human body, due to the most through touch screen luminance-reduction to second
Brightness, therefore, the second brightness herein is the least with the difference of the 3rd brightness, thus has reached protection touch screen
The purpose of operator's eyes, wherein the second detector unit can be the capacitance component in touch screen, it is also possible to be
Resistor assembly in touch screen, it is also possible to be the infrared touch frame of infrared touch panel.
It is also preferred that the left be not detected by environmental light brightness dimmed time, described touch screen brightness is being dropped from the first brightness
Before as little as second brightness, by first frequency periodically detecting touch screen surrounding brightness；Detecting
When environmental light brightness is dimmed, by described touch screen brightness from the first luminance-reduction to the second brightness, simultaneously by
One frequency brings up to second frequency, and presses second frequency periodically detecting touch screen surrounding brightness, the
Two frequencies may be configured as 100Hz.The scheme using second frequency higher can be adjusted from the first brightness at touch screen
Whole to the change judging rapidly surrounding environment light after the second brightness, if environmental light brightness holding is constant, the most right
Touch screen brightness is adjusted, if environmental light brightness increases, then shows to promote rapidly brightness of display screen, to subtract
Few erroneous judgement caused because foreign body (such as: winged insect etc.) blocks sensor.
If by described touch screen brightness first time period after the first luminance-reduction to the second brightness, not
Contact action detected, then described touch screen brightness is improved to the first brightness from the second brightness.For example,
When by teacher through touch screen front, cause touch screen surrounding dimmed, the brightness of touch screen is bright from first
Degree is reduced to the second brightness, but teacher does not carry out touch control operation, therefore can recover to touch after preset duration
Screen brightness is to the first brightness.
It is also preferred that the left described by described touch screen brightness after the second luminance-reduction to the 3rd brightness, if detection
Without contact action in the second duration, then described touch screen brightness is improved to the first brightness from the 3rd brightness.
For example, when teacher writes word, then turning round with student tells about, now student needs to watch at a distance, touches
Touch screen brightness to improve to the first brightness from the 3rd brightness.It is also preferred that the left touch screen brightness can improve from the 3rd brightness
To the second brightness, then improve to the first brightness from the second brightness.
Specifically, when described touch screen brightness is improved after the first brightness from the 3rd brightness, again will
Frequency configuration is first frequency, and again detects touch screen surrounding brightness according to first frequency.
In sum, by the way of the embodiment of the present invention adjusts touch screen brightness by twice, reduce user and exist
Carry out the luminance delta of screen during contact action, further, due to user's screen when carrying out contact action
The reduction of luminance delta, thus alleviate user when contact action touch screen to eye damage.
