Description
Technical field
The present invention relates to liquid crystal display field：LED field；Man-machine interaction liquid crystal display field；It is more particularly to a kind of
Dynamic regulation liquid crystal display LED backlight with reach improve liquid crystal display backlight life method.
Background technology
Man-machine interaction liquid crystal display is widely applied in consumer field first, with the further development of science and technology, industry
Change degree more and more higher, industrial circle is also extensively using man-machine interaction liquid crystal display terminal, but liquid crystal display is because of itself
The defects of --- the time of LED backlight service life is extremely limited, and LED can produce substantial amounts of heat luminous while.
Therefore it is somewhat unable to do what one wishes especially for outdoor commercial Application in the industrial environment in face of complexity：Under outdoor solar light since it is desired that
Therefore therefore liquid crystal apparatus finishes the integral product life-span to the LED backlight of high brightness in advance because of LED restricted lifetime；It is outdoor
Temperature is higher, and LED is luminous can be along with the generation of amount of heat, therefore the device interior of high temperature can accelerate electronic component
Aging speed.In addition, as industrial equipment is for the rigors of life of product and the intelligent demand of human-computer interaction device,
Brightness and life-span to industrial human-computer liquid crystal display propose new requirement.
The content of the invention
The present invention provides a kind of method for improving the liquid crystal display LED backlight life-span, is the industrial environment for being applicable complexity, can take into account
The brightness of liquid crystal display and life-span.The present invention is realized by following steps：First, the frequency of use of man-machine interaction is passed through
Calculate the usage time and frequency of each man-machine interaction；Secondly, the quantity of human-computer interaction interface Dynamic data display variable is counted；
Then, attention rate of the operator for the change of variable when counting man-machine interaction by infrared human body heat releasing electric transducer；Again
Person, pass through light sensor sensing external environment light intensity；Finally, current man-machine display equipment is adjusted by intelligent algorithm
LED backlight brightness.
Compared with prior art, the advantage of the invention is that：
1st, it is not only to perceive ambient light simply by light sensor linearly LED backlight to be adjusted, but
Operator is predicted by the statistical method of man-machine interaction a series of complex and wishes when see the display content of liquid crystal display.
2nd, adding infrared human body heat releasing electric transducer, whether someone close to human-computer interaction device, is avoided only according to the external world to perceive
Environment adjusts the straightforward procedure of LED backlight, is truly realized the backlight life that someone uses the maximization just lighted to extend LED.
3rd, the quantity shown by the data or variable icon that count man-machine interaction is frequent come the use of look-ahead liquid crystal display
Degree, the brightness of LED backlight is adjusted by using frequent degree.
Brief description of the drawings
Accompanying drawing 1 is flow chart.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.In the present embodiment, a kind of dynamic
The method of regulation backlight mainly includes the following steps that：
First, depositing by the human body operator in the human body pyroelectricity sensor senses certain distance that is placed on human-computer interaction device
, and the angle of pyroelectric sensor perception is exactly the visible angle of display.Even if that is surrounding someone exists,
But (visual angle of people can not see liquid crystal display clearly) does not give perception behavior yet not in the display view angle of the display.
Secondly, the main behavior of operator by counting man-machine interaction for a long time, such as：Operator only watches the change of data
Frequency；Operator query history records；The statistics of the behaviors such as setting of the operator to variable parameter carrys out the people of predicted operation person
Machine interacts main purpose and behavior.By count the data that get judge operator whether need to watch for a long time display device or
Simply inquire about or change variable parameter.So it may know that whether operator needs liquid crystal display to light for a long time.
Furthermore to count man-machine interaction engineering, how many is become to the display of operator by the content of the default engineering of man-machine interaction
Amount.Showing that variable proves that the human-computer interaction interface needs to show for a long time, and display variable is fewer to prove the interface by " concern
Degree " is fewer.This is also the parameter that comprehensive anticipation backlight is shown.
Finally, current ambient brightness is perceived by light sensor, is allowed to pre- when operator needs man-machine device to show
An if suitable brightness.
In this manual, the description of reference term " one embodiment ", " the present embodiment " etc. mean combine the embodiment or
Specific features, structure, material or the feature of example description are contained at least one embodiment or example of the present invention.At this
In specification, identical embodiment or example are not necessarily referring to the schematic representation of above-mentioned term.Moreover, description is specific
Feature, structure, material or feature can combine in an appropriate manner in any one or more embodiments or example.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.For the art
Those of ordinary skill for, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these change
Enter and retouching should also be as being considered as protection scope of the present invention.
