Specific embodiment limitation.
In a first aspect, the present invention provides a kind of display device, referring to Fig. 1, the display device 100 include display panel 101,
Display control unit (not shown) and the infrared acquisition structure 102 being arranged on 101 light direction of display panel；It is infrared
Detecting structure 102 is transparent, for when having on Infrared irradiation to display panel 101, detection display panel 101 to be shone by infrared light
The position the penetrated and position that will test is exported to display control unit；Display control unit is used for according to infrared acquisition structure
Position detected by 102 carries out display control to display panel 101.
Display device 100 provided by the invention, it is red on display panel 101 to being irradiated to using infrared acquisition structure 102
Outer light is detected, and to determine irradiated position, and uses display control unit according to the position irradiated to display device
100 are controlled.Since display device 100 provided by the invention is controlled by infrared light, relative to existing skill
Art can be realized the suspension control of relatively large distance.
As an example it is assumed that display device 100 be television set, when have some shown on Infrared irradiation to television set choosing
When selecting, such as switching channels, the infrared acquisition structure 102 of television set can detect have in the options of " switching channels " it is infrared
Light irradiation, then the display control unit of television set just controls the display panel 101 pages for entering progress channel switching.
In the specific implementation, display control unit can be also used for the position according to detected by infrared acquisition structure 102
It determines the size for the infrared light spot being irradiated on display panel 101, and display panel 101 is carried out according to the size of infrared light spot
Display control.
Since display control unit can carry out display control to display panel 101 according to the size of hot spot, even if hot spot
Center it is identical, but its is of different sizes, and display control unit is different the control of display panel 101 so that
Control process is more flexible, control operation is more convenient.
As an example it is assumed that display device 100 is television set, if the facula area in infrared light some region on a television set
When big Mr. Yu's predetermined value, then display control unit controls a program or next program in television for play.
Under normal circumstances, the distance between the size of hot spot and the device of sending infrared light and display panel 101 are related, away from
From bigger, hot spot is smaller, and apart from smaller, hot spot is bigger.Therefore can be made by way of the mobile device for issuing infrared light
The distance between itself and display panel 101 change, and obtain hot spot of different sizes, thus reach to display panel 101 into
The purpose of row display control.
In the specific implementation, display control unit can be also used for the size variation situation according to infrared light spot to display surface
Plate 101 carries out display control.
Since display control unit can also carry out display control to display device 100 according to the size variation of hot spot, i.e.,
Keep the center of hot spot identical, but it becomes larger or becomes smaller, display control unit is different to the control of display panel 101,
So that control process is more flexible, control operation is more convenient.
As an example it is assumed that display device 100 is computer all-in-one machine, when having on Infrared irradiation to all-in-one machine display screen
When volume selection keys, if infrared acquisition structure 102 detects infrared light, the hot spot on display panel 101 becomes larger, and shows control
The acoustics volume of device control all-in-one machine processed increases；If infrared acquisition structure 102 detects infrared light on display panel 101
Hot spot becomes smaller, then the acoustics volume of display control unit control all-in-one machine increases small.
Under normal circumstances, the distance between the size variation of hot spot and the device and the display panel 101 that issue infrared light become
Change related, distance becomes larger, and hot spot becomes smaller, and distance becomes smaller, and hot spot becomes larger.Therefore it can pass through the mobile device for issuing infrared light
Mode, so that the distance between itself and display panel 101 is changed, so that the size of hot spot changes, to reach pair
The purpose of the progress display control of display panel 101.
In the specific implementation, infrared acquisition structure 102 can be realized using multiple structural forms, not limited this present invention
It is fixed.As shown in Fig. 2, one of alternative construction includes detection substrate and detection driving circuit, in which:
Detection substrate include multiple infrared photosensitive units 1022 in substrate 1021 of substrate 1021, scattering device and with it is each
The connected signal wire of a infrared photosensitive unit 1022；Resistance of each infrared photosensitive unit 1022 when receiving infrared light is different
Resistance when not receiving infrared light；
Detection driving circuit is used to flow through the electricity of the electric current of multiple infrared photosensitive units 1022 by the detection of each signal line
Flow valuve, and determine display panel 101 by the position of Infrared irradiation according to the current value detected.
Not due to resistance when resistance of the infrared photosensitive unit 1022 when there is Infrared irradiation is with without Infrared irradiation
Together, therefore when there is Infrared irradiation to some infrared photosensitive unit 1022, the resistance of the infrared photosensitive unit 1022 becomes
Change, the electric current for flowing through the infrared photosensitive unit 1022 also changes, i.e., the signal wire connecting with the infrared photosensitive unit 1022
On size of current change.Based on this, detecting driving circuit can be detected on display panel 101 by Infrared irradiation
Position.
Wherein, signal wire can using metal wire or other be capable of conductive material.

Direction signal line group X1, X2, X3, X4 and multiple second direction signal line group Y1, Y2, Y3, Y4；Each signal line group includes two
Data line, for example, X1 includes X1a and X1b, X2 includes X2a and X2b, and X3 includes X3a and X3b, and X4 includes X4a and X4b, Y1
It include Y2a and Y2b including Y1a and Y1b, Y2, Y3 includes Y3a and Y3b, and Y4 includes Y4a and Y4b；It is in parallel between two data lines
There are multiple infrared photosensitive units 1022；Multiple first direction signal line group X1, X2, X3, X4 and multiple second direction signal wire Y1,
Y2, Y3, Y4 group are in net distribution.
At this point, detection driving circuit is specifically used for: applying voltage to each signal line group respectively, and detect each letter
Electric current in number line group on data line；By the friendship of electric current changed first direction signal line group and second direction signal line group
Vent, which is set, to be determined as by the position of Infrared irradiation.
Being intersected due to first direction signal line group and second direction signal line group is in net distribution, and each group of signal wire
Multiple infrared photosensitive units 1022 in parallel between two data lines, therefore infrared photosensitive unit 1022 is in net distribution, therefore is worked as
It when there is Infrared irradiation in any position on display panel 101, can detect, to reduce the blind area of control.
For example, referring to Fig. 3, at a time, detection driving circuit detects that the electric current on signal wire X2 and Y2 is prominent
So increase, it can will be in crossover location, that is, Fig. 2 of the first direction signal group X2 of current break and second direction signal group Y2
The region A1 is as the position for having Infrared irradiation.At another moment, detect that the electric current on X2, X3, Y2, Y3 increases suddenly, because
This using X2, X3 and Y2, Y3 crossover location, that is, Fig. 2 in the region A2 as the position for having Infrared irradiation.
In practice, the distribution density of infrared photosensitive unit 1022 is bigger, and detection is sensitiveer, but distribution density is bigger,
The manufacture difficulty and cost of whole display device 100 can also increase, therefore can according to the actual situation and demand in actual fabrication
Select proper 1022 distribution density of infrared photosensitive unit.
It will be appreciated that although the angle in Fig. 2 between first direction and second direction is 90 ° it should be appreciated that
It is that the angle of first direction and second direction is not necessary for 90 °, as long as angle is not 0 °, it will be able to make first direction signal
It is in net distribution that line group and second direction signal line group, which are intersected, thus in practical application the size of angle can according to need into
Row setting.
Wherein, detection driving circuit can apply electricity to signal wire using successively alive mode is applied to each signal group
Pressure, the advantage of doing so is that the power consumption of display device 100 can be reduced.
It will be appreciated that infrared photosensitive unit 1022 refers to the structure to infrared photaesthesia.
In the specific implementation, referring to Fig. 5, an insulating protective layer 1023 can also be set in infrared acquisition structure 102, it is right
