Description
Technical field
The present invention relates to a kind of display device more particularly to electronic whiteboards.
Background technique
In recent years, China's science and technology achieves significant progress, especially obvious in education sector progress, with IT application in education sector
And the continuous propulsion of education skill modernization, electronic whiteboard teaching equipment gradually add media television instead of traditional blackboard
Mode enters among numerous classrooms.Under current whole world promotion energy-saving and environment friendly, healthy megatrend, as interaction
Formula electronic whiteboard, excellent to the design concept of its human health protection is important.
Summary of the invention
The main technical problem to be solved by the present invention is to provide a kind of interactive electric whiteboard by automatic anti-blue light,
It can be realized automatic attenuating blue light brightness, to protect the eyes of user.
In order to solve the above technical problems, the present invention provides a kind of interactive electronic by automatic anti-blue light is white
Plate, comprising: display circuit board, RGB gain controller, light sensation module and backlight；
Whether the brightness of the light sensation module detection environment light changes, and will test result and be sent to display circuit
Plate, if the brightness of environment light increaseds or decreases, display circuit board finds corresponding blue light according to the brightness value of current environment light
Hot spot finds corresponding blue light, feux rouges and green light gain values further according to the blue light strength point searched out in the mapping table；It is aobvious
When showing circuit board processing display signal, the gain of blue and green light and red light component and the setting of RGB gain controller in signal
Value converts, it is suppressed that it is normal to combine colour temperature for the composition of blue light.
In a preferred embodiment: further including a manual regulating module；The manual regulating module is for inputting primary antibody indigo plant
Light intensity level, display circuit board find corresponding blue light, red according to the anti-blue light strength grade that user inputs in the mapping table
Light and green light gain values；When display circuit board processing display signal, the blue and green light and red light component and RGB in signal
The yield value of gain controller setting converts, it is suppressed that it is normal to combine colour temperature for the composition of blue light.
In a preferred embodiment: 0-100 totally 101 anti-blue light strength grades are set in the manual regulating module；Its
In 0 refer to that anti-blue light strength grade is minimum, 100 refer to anti-blue light strength grade highest.
In a preferred embodiment: when the anti-blue light strength grade is 0, the colour temperature of LED light output is 4500K；It is described
When anti-blue light strength grade is 100, the colour temperature of LED light output is 14000K.
Compared to the prior art, technical solution of the present invention have it is following the utility model has the advantages that
The present invention provides a kind of interactive electric whiteboards by automatic anti-blue light, in the case where not increasing cost,
By software automatically and manually two ways, the display circuit board in System on Chip/SoC is adjusted, the blue light in light RGB three primary colours is increased
Benefit is controlled, to achieve the purpose that anti-blue light.Manual mode is to increase a blue light gain control in custom menu, i.e.,
There are 100 control points, one blue light yield value of each point adjustment, while cooperating and adjusting feux rouges gain, green light gain two values, prevents
Only color temperature shift；The intensity of anti-blue light gradually enhances from 0 to 100, and blue light strength is allowed to die down；Automated manner is by environment light
The cooperation of propagated sensation sensor is realized, is allowed when sensing environment brightness, is reduced the intensity value of anti-blue light automatically；When sensing that environment light is brighter
When, enhance anti-blue light strength value；I.e. the environment the bright more needs to suppress blue light.
Detailed description of the invention
Fig. 1 is the structural block diagram of the preferred embodiment of the present invention；
Fig. 2 is the work flow diagram of the preferred embodiment of the present invention.
Specific embodiment
The invention patent is described further in the following with reference to the drawings and specific embodiments.
With reference to Fig. 1, a kind of interactive electric whiteboard by automatic anti-blue light, comprising: display circuit board, RGB gain control
Device, light sensation module and backlight processed；
With reference to Fig. 2, whether the brightness of light sensation module detection environment light changes, and will test result be sent to it is aobvious
Show circuit board, if the brightness of environment light increaseds or decreases, display circuit board is found according to the brightness value of current environment light and corresponded to
Blue light strength point, find corresponding blue light, feux rouges and green light gain in the mapping table further according to the blue light strength point searched out
Numerical value；When display circuit board processing display signal, in signal blue and green light and red light component set with RGB gain controller
Fixed yield value converts, it is suppressed that it is normal to combine colour temperature for the composition of blue light.
The variation according to ambient brightness is thus reached, the automatic purpose increased or reduce blue light brightness.It is simultaneously
Guarantee that final output colour temperature can be presented linear variation, human eye allowed more to adapt to, while blue light brightness changes, feux rouges and
The brightness of green light has also carried out corresponding adjustment, more humane.
It with further reference to Fig. 2, is voluntarily adjusted to further facilitate user, further includes one manually adjusting mould in the present embodiment
Block；For the manual regulating module for inputting primary antibody blue light strength grade, display circuit board is strong according to the anti-blue light that user inputs
Degree grade finds corresponding blue light, feux rouges and green light gain values in the mapping table；When display circuit board processing display signal,
The yield value that blue and green light and red light component in signal are set with RGB gain controller converts, it is suppressed that blue light at
Part, it is normal to combine colour temperature.
0-100 totally 101 anti-blue light strength grades are set in the manual regulating module；Wherein 0 refer to that anti-blue light is strong
Degree grade is minimum, and 100 refer to anti-blue light strength grade highest.
When the anti-blue light strength grade is 0, the colour temperature of LED light output is 4500K；The anti-blue light strength grade is
When 100, LED light output colour temperature when 14000K.After inputting anti-blue light strength point, the light intensity of tri- kinds of colors of RGB all occurs
Steady change is presented in variation, the colour temperature that can thus allow LED light to export.
The foregoing is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited to this,
