As user, when touch area carries out touch control operation, liquid crystal display brightness is automatically lowered to 50% brightness, example in embodiment
Such as brightness can be defined according to customer demand, when user does not carry out any touch control operation and action of writing in touch area in 30s
When, liquid crystal display brightness automatic lifting to original brightness, such as factory default brightness.
After user carries out touch control operation in touch area, touch-control driving card can touch data signal transmission be given by treated
Video card or open pluggable computer module, and video card or open pluggable computer module can automatically at regular intervals
The regular continuity for monitoring whether touch data signal and data-signal.
When having touch data signal and data-signal is continuous, then it represents that user proceeds by touch control operation, at this time eyeshield work(
It can open, video card or open pluggable computer module transmit feedback command signal to video card, and video card is made to send out the back of the body
Light Regulate signal changes power panel backlight output current, backlight illumination is reduced to specified eyeshield brightness range automatically；It is tactile when having
It controls data-signal but data-signal is discontinuous, then it represents that may be user's error touch control, then eye-protecting function is not turned on, and brightness is not adjusted
It is whole.
After eye-protecting function is opened, as in continuous a period of time（Such as：30s）Video card or open pluggable computer mould
Touch data signal has been not detected in block, and video card or open pluggable computer module transmit feedback command signal to video
Card makes video card send out backlight Regulate signal, changes power panel backlight output current, backlight illumination is increased to our company automatically and is gone out
Factory's default luminance range.
When using above-mentioned eye-protecting type Combined teaching blackboard, the liquid crystal display when user is in touch area progress touch control operation
Brightness is automatically lowered to 50% brightness, such as can define brightness according to customer demand, when in 30s user in touch area not into
When any touch control operation of row and action of writing, liquid crystal display brightness automatic lifting to original brightness, such as factory default brightness, it is adaptive
The brightness of display should be adjusted, both the eyesight of effective protection operator, nor affect on the interior of the viewing display of student and spectators
Hold；Secondly, simple in structure, mechanical strength is big, is easily installed, and secure, is suitable for more matchmakers of classroom, large conference room etc.
Body, which is opened up and had simultaneously, plays the intension that the multiple functions such as display, touch-control interaction and writing on the blackboard enrich blackboard；Secondly, outer raised line
Setting, plays a certain protective role the writing layer or support plate that are installed on the first frame or the second frame, ensures whole
The stability of structure can be played in the junction of frame and further be reinforced in addition, the combination settings of groove and connecting bar
Effect keeps the connection between each piece of panel more firm while being also convenient for dismounting；Again, the setting of reinforcing rib, then it is further right
First frame is reinforced, and is prevented because of display overweight situations such as leading to frame deformation, while being carried for the installation of other hardware
For interface；Again, the surface with roughness is formed using matt coat, smooth can not only be write, but also easily wipes and have very
Strong corrosion resistance, while the technique on strong acid etching glass surface is substituted, it is more environmentally-friendly；Again, frame bar simulation blackboard and
Ambient enviroment, forms good visual effect, and central viewing area uses shallower color, instead of of high cost and be not easy to buy
Smoked glass, it is cost-effective, and there is better translucency so that electronical display is more clear.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
