It is likely more complexity.
In the following description, a large amount of details have been inquired into, to provide the more thorough explanation to the embodiment of the present invention, however,
It will be understood by those skilled in the art that it is aobvious and easy for may be practiced without these specific details the embodiment of the present invention
See, in other embodiments, well known structure and equipment is shown in block form an rather than in the form of details, with
It avoids making the embodiment of the present invention indigestion.
As shown in Figure 1, the eyes protection display device in the present embodiment, comprising: monitor body, control unit, driving unit and
Detection unit, described control unit are connect with detection unit and driving unit respectively；
Detection unit includes brightness sensing module for detecting ambient brightness and for detecting user and display screen
The distance between apart from induction module；
Control unit generates control instruction and is sent to driving unit, the driving according to the testing result of detection unit
Unit is adjusted the state of monitor body according to control instruction, and the state of the monitor body includes at least display
The combination of one or more of unlatching, closing, standby, position and the brightness of device ontology.
In the present embodiment, control unit receives the ambient brightness data of brightness sensing module induction, when control unit ring
When border brightness is lower than pre-determined lower limit brightness, control unit adjusts the brightness of display screen, to adapt to the variation of ambient brightness, with protection
The eyesight of viewer guarantees optimal viewing effect；In addition, being detected between user and the display screen of display apart from induction module
Distance, and the range data that will test is exported to control unit, the range data that control unit relatively detects and default
Minimum viewing distance size, when the range data detected is less than preset minimum viewing distance or be greater than maximum safety
Apart from when, control unit can control alarm unit work alarm, remind viewer's viewing distance it is too small, to help to watch
Person keeps good viewing habit, keeps good eyesight.Preferably, the brightness sensing module in the present embodiment is photosensitive two pole
Pipe or photo resistance, display screen can be liquid crystal display, and liquid crystal display includes liquid crystal mainboard and display screen, control unit
It can be connect with liquid crystal mainboard, when control module judges that ambient brightness is less than pre-determined lower limit brightness, export control signal to liquid
Brilliant mainboard, liquid crystal mainboard adjust automatically show the brightness of screen, are range sensor apart from induction module.
It in the present embodiment, further include power module, the detection unit further includes temperature sense module and humidity inductive
Module, for the temperature and humidity of environment where detecting display, the power module is connect with control unit, when what is detected
Temperature is greater than preset maximum temperature, alternatively, when the humidity detected is greater than preset maximal humidity, described control unit control
Power module processed stops power supply.Temperature sense module specifically uses temperature sensor to realize, humidity inductive module specifically uses
Humidity sensor realizes that power module is connect with control module, power module provides operating voltage, humidity for eyes protection display device
The output end of induction module, the output end of temperature sense module are connect with the input terminal of control module, and temperature sense module is used
The temperature level of environment where detection display, the humidity size of environment where humidity inductive module is used to detect display,
And the temperature that will test, humidity data are sent to control module, temperature that control module relatively detects, humidity data and pre-
If maximum temperature, maximal humidity size, when the humidity detected be greater than preset maximal humidity when, control module control electricity
Source module disconnection does not work, then whole display does not work, and prevents display from also leading to short circuit because of the environment in high humility；When
When the temperature detected is greater than preset maximum temperature, control module control power module disconnection does not work, then whole display
It does not work, prevents display from exception occur because being in the environment of high temperature.
In this example it is shown that device body bottom portion is provided with the pedestal for carrying monitor body, driving unit packet
Driving arm is included, the driving arm 3 is set between monitor body 1 and pedestal 2, is shown for adjusting according to control instruction
The position of device ontology 1, user can adjust the height that monitor body 1 is display screen by driving arm 3, to be adapted to viewer
Height, reach optimal viewing height.One specific embodiment of driving arm 3, driving arm 3 are not limited to shown in Fig. 2
Structure, as shown in Fig. 2, driving arm 3 be arranged between monitor body 1 and pedestal 2.
In the present embodiment, detection unit further includes face detection module and eyeball tracking module, described control unit root
Judge the use state of user according to face detection module and eyeball tracking module, described control unit is according to the use state of user
Control the unlatching of display, closing and standby.If detecting user within the scope of preset distance threshold, and eyeball is not paid close attention to
When the time of display is less than preset time threshold, then determine that user is in use state；If detecting user default
Distance threshold range outside or eyeball do not pay close attention to display time be greater than preset time threshold when, then determine that user is in
Non-working condition.When user is in use state, and described the distance between user and display are detected apart from induction module
When less than pre-set minimum safe distance or being greater than maximum safe distance, described control unit controls driving unit to display
The position of device is adjusted, and is in the distance between user and monitor body in preset safe distance, as judgement user
When in non-working condition, can control display close or it is standby it is equal operate, when user is in use state, Ke Yidong
The distance between the adjustment user of state and display, ensure that relative distance between the two in this way, can effectively protect
Protect user eyesight, will not due to user's sitting posture change and cause hypotelorism or too far the case where generation.
It in the present embodiment, further include calibration unit, the calibration unit is connect with control unit, in display sheet
The calibration point that display plane intersects with eyeball parallel lines of sight is set on body, and described control unit adjusts aobvious according to the calibration point
Show the position of device ontology.
In the present embodiment, prover time threshold value and calibrated distance threshold value are preset, when user is in use state,
If the distance between the position that user eyeball parallel lines of sight intersects with display plane and calibration point are greater than the calibrated distance threshold
When the time for being worth, and maintaining is more than prover time threshold value, described control unit controls driving unit and carries out position to monitor body
Set adjusting, the position for intersecting user eyeball parallel lines of sight with display plane and the calibration point be less than calibrated distance threshold value or
It is overlapped, family can be used in this way mobile etc. in special circumstances in body inclination, seat, still can keep and show
Show that good distance and the relative position of device can effectively prevent erroneous judgement by prover time threshold value and calibrated distance threshold value
It is moved in vain with frequent mobile bring.
