Abstract
The invention provides a display device with a photographing function, which comprises a power supply, a photographing module, a display screen and a control module, wherein the display screen has an electrically-controlled liquid crystal dimming function; the photographing module is arranged on the back of the display screen, and used for photographing objects in front of the display screen; the control module is used for controlling the power supply to power on or off the display screen, thereby driving the display screen to be quickly switched between a non-light-tight mode and a light-tight mode, and controlling that the photographing frequency of the photographing module and the switching frequency (between the non-light-tight mode and the light-tight mode) of the display screen are synchronous or in a multiple relation. By using the display device with the photographing function provided by the invention, a user does not have to carry out photograph by manually adjusting a camera.
Description
Technical field
The present invention relates to a kind of display device with camera function.
Background technology
Under the prior art; Display device is all through installing a camera above its screen; User to its place ahead photographs through this camera; And the user's of the gained of will photographing image is transferred to other display device; Realize that so different users when chat, can see the other side's image each other.But; Because camera is provided with above display screen; So cause camera to be merely able to absorb user's head; And can not absorb other places of user; When the user wants to absorb the position of other adjustment display screens that just must not stop local the time; So, waste user's time, and be inconvenient to operate.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of display device with camera function, and it utilizes a photography module when the display screen printing opacity of a tool electrically-controlled liquid crystal light modulation, the object in its place ahead is photographed, thereby address the above problem.
The present invention provides a kind of display device with camera function; Comprise a power supply and a photography module; This display device also comprises: the display screen of a tool electrically-controlled liquid crystal light modulation and a control die set, and this photography module is arranged at the back side of display screen, is used for the object in display screen the place ahead is photographed; This control die set be used to control power supply give this display screen energising or no power order about this display screen fast printing opacity with light tight between switch and the photographic frequency of control photography module and this display screen perhaps become multiple to concern in that printing opacity and the switching frequency between light tight are synchronous.
Display device with camera function of the present invention; Its utilize display screen that a control die set controls a tool electrically-controlled liquid crystal light modulation printing opacity and light tight between switching frequency and a photography module photographic frequency synchronously or becomes multiple to concern; Make this photography module under the situation that the user does not discover, can photograph to the object in display screen the place ahead; And the image of photography is sent to other display device, realize effect interactive between the user.

Embodiment
Please refer to shown in Figure 1ly, this display device 1 with camera function comprises display screen 50, a power supply 40 and a storage unit 20 of a processing unit 10, a communication unit 30, a tool electrically-controlled liquid crystal light modulation.In this embodiment; This display screen 50 is a kind of electrically-controlled liquid crystal light modulation glass; Constitute by layer glass and the crystalline state liquid crystal that is poured between the layer glass; When giving electrifying electrodes on glass; Interlayer liquid crystal arrangement form is arranged again and is made this display screen 50 become transparent, thereby can see the object on these display screen 50 opposites; And when powered-down; Interlayer liquid crystal arrangement form is recovered unordered structure, thereby it is opaque to make that this display screen 50 becomes again, and this moment, this display screen 50 was a rear projection type screen; Also promptly in the rear projection of this display screen 50, the picture of projection may be displayed on the front of this display screen 50.In other embodiments, this display screen 50 also can be made up of double-layer films and the crystalline state liquid crystal that is poured between the double-layer films, perhaps by one deck glass and thin film and be poured in glass and film between the crystalline state liquid crystal constitute.
This processing unit 10 comprises a control die set 12, a photography module 11, an and projection module 13.
This control die set 12 is used to control power supply 40 and gives display screen 50 energising or no powers, order about this display screen 50 fast printing opacity with light tight between switching.
This photography module 11 is arranged at the back side of display screen 50, is used for when display screen 50 printing opacities, the object in display screen 50 the place aheads being photographed, and the picture of photography is stored in storage unit 20.Under the prior art, have only when the refreshing frequency of display screen is at least 60Hz, user's eyes could be watched the picture on the display screen normally, are unlikely to feel eye fatigue.Therefore, control die set 12 control display screen 50 switching frequency during between energising and no power only greater than 60Hz, the user just can be because of the printing opacity of the imperceptible display screen 50 of persistence of vision and light tight switching, and eyes can not felt fatigue.Simultaneously; Because photography module 12 is only when display screen 50 printing opacities; Just can photograph to the object in display screen 50 the place aheads; Also promptly photograph module 12 photographic frequency must with display screen 50 at printing opacity and light tight 's switching frequency synchronously or when becoming the concerning of multiple, can guarantee that just this photography module 12 photographs to the object in display screen 50 the place aheads normally.So; In the present embodiment; The switching frequency of these control module 40 pairs of display screens 50 of 12 control power supplys between energising and no power is greater than the refreshing frequency 60Hz of the minimum display screen that can receive 50 of eyes of user; Simultaneously; The photographic frequency that this control module 12 is also controlled photography module 11 perhaps becomes multiple to concern with the switching frequency of display screen 50 between energising and no power is synchronous; So; In the time of just can guaranteeing the picture on watching display screen 50; User's eyes will be because of the switching of the imperceptible display screen 50 of the influence of the persistence of vision printing opacity and light tight, and the module 11 synchronous objects to display screen 50 the place aheads that can also guarantee to photograph are simultaneously photographed.This communication unit 30 is used for the operation according to the user, the photographic picture of being stored in the storage unit 20 is transferred to other display device.
This projection module 13 is arranged at the back side of display screen 50, is used for when display screen 50 is light tight, carrying out projection at the back side of display screen 50.In this embodiment, because this display screen 50 is a rear projection type screen when light tight, so the user just can see the picture that projection module 13 throws at display screen 50 back sides in the front of this display screen 50.
