Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by.
The embodiment of the present invention provides a kind of display methods, and the display methods is applied to television set, and computer is put down
The equipment with display function such as plate computer, the embodiment of the present invention is illustrated by taking television set as an example.It is described aobvious
Show method as shown in figure 1, including：
Step 101, detection the distance between user and display device.
When television set normally shows, user may unconsciously from television set increasingly close to, it is too near if
May harm users eyes health, therefore television set in the process of running can every Preset Time,
Detection once the distance between with user, in order to take necessity when user and television set are closer to the distance
Measure.Conventional distance detection method has the methods, the present invention such as infrared distance detection, ultrasonic distance detection
Embodiment is not limited this.
Step 102, the corresponding relation according to distance and interference coefficient, determine the user and display device it
Between the corresponding interference coefficient of distance.
Example, in order to when user and television set are closer to the distance, remind user away from television set, can be pre-
The corresponding relation of distance and interference coefficient is first stored in a television set, and the corresponding relation can represent the user
It is inversely proportional with the interference coefficient with the distance between display device.That is, when user and television set
Distance is nearer, and corresponding interference coefficient is bigger, and user is more remote with the distance of television set, corresponding interference coefficient
It is smaller.
Step 103, according to the interference coefficient display image.
Example, the image shown by display device can include pattern and word.Optionally, according to institute
When stating interference coefficient display image, the image of predeterminable area according to the interference coefficient, can be shown.For example,
Detection is obtained after the distance between user and television set, obtains this apart from corresponding interference coefficient, Ran Hougen
The image of predeterminable area is shown according to the interference coefficient, specifically, assuming to divide the display interface of display device
It is 9 regions, chooses a region of center as predeterminable area, the predeterminable area is in advance aobvious
Show the region of variation set on interface.After getting interference coefficient, then show default according to this interference coefficient
The image in region.Example, user's interference coefficient corresponding with the distance between display device is 0.8, described
Predeterminable area includes 340*340 pixel, in the corresponding image of display predeterminable area, can give preset areas
The original gradation of each pixel in domain is multiplied by interference coefficient, obtains showing for each pixel in predeterminable area
Show gray scale, using each pixel in corresponding display gray scale display predeterminable area so that predeterminable area shows
Image it is integrally dimmed, cause display effect poor.User is poor in the display effect for perceiving predeterminable area
When, it can be appreciated that to too near with television set distance, and then away from television set.
Optionally, when according to the interference coefficient display image, the pixel of predetermined number can be randomly selected,
Then according to the interference coefficient, the pixel is shown.For example, detection is obtained between user and television set
After distance, this is obtained apart from corresponding interference coefficient, then randomly select the pixel of predetermined number, it is assumed that
The number of pixels of the viewing area of display device is total up to 1024*1024, and selection that can be random is therein
1024*100 pixel, after getting interference coefficient, can show the pixel according to this interference coefficient.Show
Example, it is assumed that pixel A is any one in the 1024*100 pixel for randomly selecting, user with show
The corresponding interference coefficient of the distance between equipment is 0.8, and the original gradation of pixel A is 120, in display pixel
During A, the original gradation of pixel A can be multiplied by interference coefficient and be shown, i.e., when pixel A finally shows
Gray scale be 120*0.8, it is dark when so pixel A can be caused to show.If to random selection
The 1024*100 original gradation of pixel is multiplied by interference coefficient and is shown so that the 1024*100 picture
Element is dark so that whole image is presented the effect of flower screen, causes display effect poor.Perceiving display
When effect is poor, user can be appreciated that with television set distance too closely, and then away from television set.
So, due to the interference coefficients that different distance correspondences are different, thus can according to user with it is aobvious
Show that the different distance between equipment determines different display effects, with this remind user currently with display device
Whether distance is suitable so that the adjustment that user can be in good time and the distance of display device, protects eyesight, improves
The operability of display device, and then improve Consumer's Experience.
Further, before the distance between the detection user and display device, can also detect first
The continuous working period of the display device, then when the run time is less than or equal to time threshold,
The distance between detection user and display device.
Example, prolonged viewing TV programme can also produce injury to the eye health of user, therefore,
Before distance between detection user and television set, the viewing time of user can also be first detected, i.e. electricity
Depending on the machine current continuous working period, if television set existing continuous run time is more long, electricity can be made
Black picture a few minutes are exported depending on machine, points out user's viewing time more long, promoted user to close one's eyes and rest；If electric
It is shorter depending on machine existing continuous run time, can detect the distance between user and television set, and according to
Distance regulation display picture, promotes user away from television set, is seen on the basis of eye health is ensured as far as possible
See TV programme.Specifically, can be with default settings time threshold, it is then determined that television set existing continuous run
Whether the time is more than time threshold, and when existing continuous run time is more than time threshold, television set it is aobvious
Show that interface exports black signal, when existing continuous run time is less than or equal to time threshold, detect user
The distance between with television set.
Further, when display device is initialized, the password of user input can also be received, if then institute
When the password for stating user input is with the password match for prestoring, user input change information is pointed out；According to receiving
User input change information, change the corresponding relation of the distance and interference coefficient, and/or the time
Threshold value.
Example because many young father and mother have no time to look after child, child be probably after school alone in
Family, sets viewing time and viewing distance, it is ensured that the eye health of child, but some children can
TV programme can be sought, the parameter for pre-setting can be changed so that the restriction of viewing time and viewing distance is made
With failure, and then cause the immoderate viewing TV programme of child, injure eye health.On preventing
Situation is stated, father and mother can be preset in television set memory storage password, if user needs change to set, television set
User input password can be first pointed out, only when the password of user input is with the password match for prestoring,
User's Reparametrization is just allowed, i.e., when the password and the password match for prestoring, TV of user input
Machine can point out user input new time threshold and viewing distance, and according to the information of user input, change is former
The distance and the corresponding relation of interference coefficient come, and/or time threshold.Wherein, the matching can refer to input
Password it is identical with the password of storage, or can also be matched according to preset rules, for example, in advance
The password of storage is 321, adds 1 during preset rules, then when user input 432, illustrate the close of user input
Code and the password match for storing.So, child can be avoided to agree to the ginseng that modification is set without father and mother
Number, and then avoid the immoderate viewing TV programme of child.
A kind of display methods is the embodiment of the invention provides, including：First between detection user and display device
Distance, and according to distance and the corresponding relation of interference coefficient, determine between the user and display device
Apart from corresponding interference coefficient, then according to the interference coefficient display image.Compared to prior art, by
In the different interference coefficient of different distance correspondences, therefore can be according to the difference between user and display device
Distance determines different display effects, reminds user whether the distance currently with display device is suitable with this, makes
User can be in good time adjustment and display device distance, protect eyesight, improve grasping for display device
The property made, and then improve Consumer's Experience.
The embodiment of the present invention provides a kind of display methods, and the display methods is applied to television set, and computer is put down
The equipment with display function such as plate computer, the embodiment of the present invention is illustrated by taking television set as an example.It is described aobvious
Show method as shown in Fig. 2 including：
Password, time threshold, dormancy time and distance and interference coefficient that step 201, storage user are set
Corresponding relation, perform step 202.
User when display device is used first, it is possible to use supporting remote control is configured to display device,
Limit the username and password of the operating right of display device, corresponding relation of the distance with interference coefficient, time
Threshold value, and equipment dormancy time.Display device described in the embodiment of the present invention has parameters memorizing function,
Establish the automatic loading last parameter information for setting during machine after being provided with, on next time by cable.
Example, when user is initially opened power supply, television set can point out user input time threshold, dormancy
The corresponding relation of time and distance and interference coefficient.Wherein, time threshold refers to user can continue to watch
The maximum duration of TV programme, dormancy time refers to television set when determining that the lasting viewing time of user is long
The time of display image can be stopped, distance can be that staff sets in advance with the corresponding relation of interference coefficient
Each rank of interference coefficient is put, user only needs corresponding according to necessarily disturbance grade is sequentially inputted
Distance, for example, it is assumed that staff pre-sets 5 interference coefficient ranks, interference coefficient is by small
Be respectively 0.2,0.4,0.6,0.8 and 1 to big, descending 4 of user input apart from when, in order with
Each interference coefficient carries out correspondence.
For example, during initialization, television set can show first on screen " please be input into maximum viewing duration with
Dormancy time ", is then stored as time threshold by first time of user input, and second time is stored as
Sleep time, then display " please according to from big to small sequentially input 4 distances ", Yong Hufen on screen
The distance not being input into is 2.5 meters, 2 meters, 1.5 meters, 1 meter, it is assumed that the distance between user and television set are L,
Then as L ＞ 2.5, there is no corresponding interference coefficient；As 2.5≤L ＜ 2, corresponding interference coefficient is 0.2；
As 2≤L ＜ 1.5, corresponding interference coefficient is 0.4；As 1.5≤L ＜ 1, corresponding interference coefficient is 0.6；
When L≤1, corresponding interference coefficient is 0.8.Now the corresponding relation of the distance and interference coefficient can be as
Shown in table 1：
The corresponding relation of the distance of table 1 and interference coefficient
| Apart from L (rice) | Interference coefficient |
| L ＞ 2.5 | |
| 2.5≤L ＜ 2 | 0.2 |
| 2≤L ＜ 1.5 | 0.4 |
| 1.5≤L ＜ 1 | 0.6 |
| L≤1 | 0.8 |
As shown in Table 1, distance is nearer, and corresponding interference coefficient is bigger.Distance is processed as rate range
Purpose is that real-time adjustment display picture is not needed when distance change is unconspicuous, improves the operation effect of system
Rate.It should be noted that in practical application, it is also possible to set apart from lower limit Lmix, when user and TV
When the distance between machine L is less than Lmix, completely black picture is shown, the table 1 in the embodiment of the present invention is only right
Distance is illustrated with the corresponding relation of interference coefficient, does not limit the concrete mode of the corresponding relation.
In practical application, the parameter setting of television set is tampered in order to avoid other users, it is also possible to set
Password, i.e., only when the password match of user input, just allow user to change parameter setting, wherein parameter
The corresponding relation for being time threshold and/or distance and interference coefficient is set.For example, suitable according to specifying in user
After sequence transmission range, television set can also point out user input password, then enter the password of user input
Row storage, is used to determine whether that user changes parameter setting in order to the later stage.
In practical application, time threshold and distance can be stored with the corresponding relation of interference coefficient and deposited in ROM
In storage chip, unless the removing of row write 0 treatment is entered to the data of the ROM storage chips, even if otherwise system
It is lower electricity/reset will not also lose, as long as that is, user initialization when input once, even if later deenergization it
Afterwards, start shooting again, it is not required that re-enter parameter setting.In system initialization, can be defeated by user
The time threshold for entering and the distance determined according to the distance value of user input are stored with the corresponding relation of interference coefficient
In the ROM, when image display is carried out, by the time threshold and distance pass corresponding with interference coefficient
System is read in internal memory, is used during for Video processing.
Specifically, can also by with mobile terminal, the binding of such as mobile phone complete password, time threshold,
The input of dormancy time and distance and the corresponding relation of interference coefficient.For example, initialization when, can first by
Television set is bound with mobile phone, and television set also includes by wireless transport module, by the wireless transport module
Prompt message is sent to mobile phone, the various information of user input are pointed out according to the prompt message in order to mobile phone, and
And the password, time threshold, dormancy time and the distance that will be obtained according to user input are corresponding with interference coefficient
Relation is sent to television set, is stored in order to television set.
Step 202, detection existing continuous run time, perform step 203.
In order to avoid user, viewing TV programme are damaged to eyes for a long time, can set timer, should
Timer starts timing after user turns on the power.
Step 203, judge the continuous working period whether less than or equal to time threshold；If continuous service
Time is less than or equal to time threshold, performs step 204；If the continuous working period is more than time threshold, hold
Row step 207.
The timing of timer is obtained, whether the timing is determined less than or equal to time threshold, if the timing is small
In or equal to time threshold, illustrate that the continuous working period of television set is shorter, user does not have viewing for a long time
TV, it is only necessary to adjust the distance between user and television set, you can avoid the eye health of user from being hindered
Evil.If the timing is more than time threshold, illustrate that user has timed, out viewing, no matter user and television set it
Between distance whether rationally, be required to take certain measure, promote user to rest.
Step 204, detection the distance between user and display device, perform step 205.
If the continuous working period of television set is less than or equal to time threshold, user is illustrated without viewing for a long time,
But it is excessively near with the distance between television set if user is when TV programme are watched, still may be to user
Eyes damage, therefore also need to determine the distance between user and television set.Under normal circumstances can be with
By ultrasonic distance detection method, or infrared determine between user and television set apart from modes such as detection methods
Distance, the embodiment of the present invention is not limited this.
Step 205, the corresponding relation according to distance and interference coefficient, determine between user and display device
Apart from corresponding interference coefficient, step 206 is performed.
Example, it is assumed that detect that the distance between user and display device L is 1.75 meters, by inquire about away from
From the corresponding relation with interference coefficient, it may be determined that go out interference coefficient corresponding apart from L.Assuming that distance with it is dry
Disturb the corresponding relation of coefficient as shown in table 1, by inquiry table 1, apart from L more than 1.5, be less than
In the range of 2, its corresponding interference coefficient is 0.4.
Step 206, according to the interference coefficient, show the image of predeterminable area, perform step 208.
Example, the display panel of television set can be divided into 9 regions according to the form of nine grids in advance,
Then most middle region is chosen as predeterminable area.When user's interference corresponding with the distance between television set
When coefficient is 0.4, original by predeterminable area each pixel can read to be multiplied by 0.4 display for obtaining each pixel
Gray scale, then shows each pixel of predeterminable area using corresponding display gray scale so that predeterminable area it is aobvious
Show that effect is substantially dimmed, the display quality of whole picture is remarkably decreased, because predeterminable area is just seen in user
See the emphasis position of TV programme, when predeterminable area it is dimmed when, it is easy to so that user perceives, and then
Recognize closely to be caused very much due to the distance between oneself and television set the change of display quality, promote user
Away from television set.
Step 207, completely black picture is shown in sleep time, perform step 208.
If the continuous working period of television set is more long, illustrate that the time that user persistently watches is more long, may be right
Eyes produce injury.Therefore, when time threshold is more than in the continuous working period for detecting television set, stop
Completely black picture is shown in dormancy duration on the display panel of television set, is used to point out user to watch time-out, it is necessary to close
Eye rest.
Step 208, when user need change parameter setting when, receive user input password, perform step
209。
The distance of size or seat according to room, user may also need to be modified parameter setting.
But, if allowing user arbitrarily to change parameter setting, it is possible that some children are same without father and mother
Parameter setting is modified in the case of meaning, so may result in the immoderate long-time low coverage of child
From viewing TV, the eye health to child has a negative impact, therefore, need to set parameter in user
Put when being modified, it is necessary first to point out user input password, current use is determined whether using password
Change parameter setting in family.
If the password of step 209, user input and the password match for prestoring, user input change is pointed out
Information, performs step 210.
If the password match prestored in the password of user input and television set, illustrates it is normal user
The change of parameter setting, now can successively point out user input time threshold according to the pattern of initialization,
Sleep time, and/or distance parameter, i.e., described change information can include the new time threshold of user input,
New sleep time, and/or new distance parameter.
In practical application, television set can also include wireless transport module, if continuous three inputs of user
Password of the password with storage in television set is inconsistent, or user uses enforced reset system, removes parameter
During setting, information, prompting mobile telephone set user are sent to the mobile phone bound with the television set by wireless transport module
Someone wants, without modification parameter setting is agreed to, to be processed in order to user.
Step 210, the change information according to the user input for receiving, modification distance are right with interference coefficient
Should be related to, and/or time threshold.
After the change information for receiving user input, when can cover original using new time threshold
Between threshold value, original sleep time is covered using new sleep time, using new distance and interference coefficient
Corresponding relation covers the corresponding relation of original distance and interference coefficient, wherein new distance and interference coefficient
Corresponding relation is obtained by new distance parameter.
It should be noted that the adaptable display device of display methods described in the embodiment of the present invention includes master
Control module, signal input module, signal output module and apart from detection module.Wherein signal input mould
Block includes various analog and digital signal interfaces, receives simulation or the input of data-signal, you can to receive video
Signal；Signal output module includes the interface matched with TV or display, and main control module has been processed
Data output is to display device；Apart from detection module, the distance between user and display device are detected, and will
The Distance Transmission is for further processing to main control module；Main control module is detected by apart from detection module
The actual range for arriving, obtains the corresponding interference coefficient of the actual range, then by the interference coefficient to input
Vision signal is transmitted to signal output module after being processed, signal output module is exported to display screen, is easy to show
Display screen is shown.
A kind of display methods is the embodiment of the invention provides, compared to prior art, because user sets with display
It is the distance between standby to be inversely proportional with the interference coefficient, therefore, when user and display device it is closer to the distance when,
Corresponding interference coefficient is larger, when according to the interference coefficient display image, can cause the display effect of image
It is deteriorated, reminds user that the distance currently with display device is too near with this so that user can be in good time away from aobvious
Show equipment, protect eyesight, improve the operability of display device, and then improve Consumer's Experience.
The embodiment of the present invention provides a kind of display device 30, including：
First detection unit 301, for detecting the distance between user and described display device 30.
In practical application, the first detection unit 301 can be using infrared apart from detection method, and ultrasonic distance is visited
The modes such as survey method are adjusted the distance and are detected, the embodiment of the present invention is not limited this.
Determining unit 302, for according to distance and the corresponding relation of interference coefficient, determining the user and showing
Show the corresponding interference coefficient of the distance between equipment 30.
Example, in order to when user and television set are closer to the distance, remind user away from television set, can be pre-
The corresponding relation of distance and interference coefficient is first stored in a television set, and the corresponding relation can represent the user
It is inversely proportional with the interference coefficient with the distance between display device.That is, when user and television set
Distance is nearer, and corresponding interference coefficient is bigger, and user is more remote with the distance of television set, corresponding interference coefficient
It is smaller.
Display unit 303, for according to the interference coefficient display image.
Optionally, the display unit 303 can first randomly select the pixel of predetermined number, then basis
The interference coefficient, shows the pixel.
Or, optionally, the display unit 303 can also show preset areas according to the interference coefficient
The image in domain.
