For example, the LCD Panel 100 according to the embodiment of the invention comprises: display panels 101, module backlight 102, shooting module 103 and control module 104.As shown in Figure 1, module 102 backlight can be arranged on the rear side of display panels 101.In addition, for example, opening (through hole) is set, and in this opening, inserts the shooting module 103 such as CMOS type camera at the middle section of module 102 backlight.Control module 104 is connected with display panels 101, module backlight 102 and shooting module 103, and can control the operation of display panels 101, module backlight 102 and shooting module 103.
According to embodiments of the invention, display panels 101 can by the display panels of any type (as, TFT, CSTN, PLS etc.) form, and can come display image based on the picture signal that provides from external device (ED).Here described external device (ED) can be computing machine, also can be the part except display screen on notebook, mobile phone, PDA or the all-in-one.For example, central processing unit on the notebook (CPU) or video card etc.Display panels 101 can change arranging (promptly of its inner liquid crystal molecule based on picture signal; Light transmission state) shows image with the light that utilizes module 102 backlight to send with different tones and brightness; That is to say that display panels 101 can be changed between printing opacity (different transmittances) and light tight state.
In addition, module 102 backlight can comprise any backlight that is applicable to LCD Panel.When module 102 backlight was opened, this module backlight 102 was luminous, and display panels 101 utilizes light that module 102 backlight produces, produces the macroscopic image of user based on the picture signal that is provided.For example; Display panels 101 can be based on the picture signal that receives from external device (ED); Change the arrangement of its inner liquid crystal molecule, thereby make light from module 102 backlight see through display panels 101 and the polaroid that is provided with produces the image with different hue and luminances with colour filter film (not shown) above that.Because the present invention do not relate to the change to display panels 101, and its structure is known with operation to those skilled in the art, therefore omitted each layer of display panels 101 and the detailed description of operation thereof here.Otherwise when module 102 backlight was closed, because display panels 101 itself can not active illuminating, even therefore to display panels 101 the pictures different signal is provided, the user can not see the image that is produced.
Below, with describing the operation of carrying out according to the LCD Panel 100 of the embodiment of the invention.Fig. 2 is the process flow diagram of diagram according to the operation of LCD Panel 100 execution of the embodiment of the invention; Wherein Fig. 2 A is the situation that LCD Panel 100 normally shows, and Fig. 2 B is the operation that LCD Panel 100 is carried out when carrying out IMAQ of shooting module 103.
Shown in Fig. 2 A; According to the normal display image of the LCD Panel of the embodiment of the invention 100 time, shooting module 103 is not worked, and module backlight 102 is opened and luminous; And LCD Panel 100 receive from external device (ED) (as, video card or CPU) picture signal that provides.In this case; Display panels 101 is based on the picture signal that receives from external device (ED); Change the arrangement of its inner liquid crystal molecule, thereby make light from module 102 backlight see through display panels 101 and the polaroid and the colour filter film (not shown) that are provided with produce pictures different above that.Because the present invention do not relate to the change to display panels 101, and its structure is known with operation to those skilled in the art, therefore omitted each layer of display panels 101 and the detailed description of operation thereof here.
According to embodiments of the invention; Owing on the central area of module 102 backlight, be provided with opening; And in this opening, be provided with shooting module 103; So on this zone, do not have light source (because shooting module 103 is not luminous), therefore, possibly go up the generation stain at the correspondence position (central area) of liquid crystal panel owing to the disappearance of light source.Yet; Since according to an embodiment of the invention LCD Panel 100 adopt undersized shooting module (as; Littler area below 1 square millimeter or under the situation of the shape of appropriate design opening); And the light that sends parameatal backlight on the module 102 backlight can compensate the disappearance of the light source on this aperture position; Therefore, the locational brightness of image (display pixel brightness) corresponding with shooting module 103 is only should images displayed brightness dark slightly than it on display panels 101, and the user is difficult to aware such brightness variation.Therefore the user is difficult to notice and in LCD Panel 100, is provided with shooting module 103.
To be described in when using shooting module 103 to sample the operation that LCD Panel 100 is carried out below.
Now, will be that example is described the operation according to the LCD Panel 100 of the embodiment of the invention with the situation of the refresh rate display image of 60Hz with LCD Panel 100.Shown in Fig. 2 B,, utilize LCD Panel 100 to carry out under the situation of video calling or video conference the user according to the embodiment of the invention, the user can be through the image collecting function of input block (not shown) primer fluid crystal display screen 100.During shooting module 103 carried out the collection of image, control module 104 every separated preset times were closed module 102 backlight at interval, got into transparent state with shooting module 103 corresponding zones at least on the control module 104 control display panels 101 then.At least corresponding with shooting module 103 zones get into after the pellucidity on display panels 101, control module 104 controls modules 103 images acquired of making a video recording.After shooting module 103 images acquired were accomplished, control module 104 was opened module backlight, and said display panels is based on the picture signal display image that offers display panels 101.Wherein, control module 104 can make display panels 101 get into pellucidity through image is provided to display panels 101.Preferably, this image that provides is a white image.
Particularly; For example; In the 1/60th second time period (16ms), module 102 backlight is opened, and the picture signal that display panels 101 provides based on external device (ED) comes normal display image then in the 2/60th second time period (16ms); When IMAQ began, control module 104 was at first closed entire aphototropism mould 102.Then, control module 104 abandons the picture signal (that is, the 2/60th second the picture frame that does not use external device (ED) to provide) that external device (ED) provides, and makes on the display panels 101 at least the zones entering pellucidity corresponding with shooting module 103.For example, control module 104 can make the display panels 101 whole pellucidities that get into through white image is provided to display panels 101.Here; Provide the purpose of white image to be to display panels 101; Liquid crystal layer in the display panels 101 has the highest transmittance appearing under the situation of white image, arrives shooting modules 103 thereby can make more rays pass through this display panels 101.Yet, the invention is not restricted to this, can make the display panels 101 whole pellucidities that get into through other image (like, grey) is provided to display panels 101.Perhaps can also provide on the zone corresponding arbitrary image for white to make on the display panels 101 the zones entering pellucidity corresponding to display panels 101 with shooting module 103 with the module 103 of making a video recording.In addition, under display panels 101 situation for normal white liquid crystal display panel (at making alive not time be to present white picture), can be through ending to provide voltage to make the display panels 101 whole pellucidities that get into to display panels 101.
For example; At least get under the situation of pellucidity with shooting module 103 corresponding zones through making on the control display panels 101 at control module 104 to display panels 101 transmission images; Because module 102 backlight is closed and is not luminous; Therefore, the user can not see the film flicker (transferring complete white or other image etc. like, picture suddenly to) of LCD Panel 100.Another purpose of in addition, closing module 102 backlight is that the influence of light of avoiding module 102 backlight to produce sees through the light of display panels 101 (the IMAQ effect of influence shooting module 103).In this case, because corresponding with shooting module 103 at least zone can printing opacity on the display panels 101, therefore, the module 103 of making a video recording can utilize the light that sees through from display panels 101 to come images acquired.
Make on the display panels 101 at least with after shooting module 103 corresponding zones get into pellucidity at control module 104, control module 104 starts the modules 103 of making a video recording and comes images acquired.Next; Accomplish or after the predetermined collection concluding time arrives at the IMAQ of shooting module 103; At the 3/60th second; Control module 104 is closed shooting module 103, opens module 102 backlight then, and the picture signal that control display panels 101 provides based on external device (ED) is come display image normally.Then, control module 104 repeats above-mentioned action.For example; Control module 104 was controlled the collection (description in said 2/60 second is identical) that display panels 101, module backlight 102 and shooting module 103 are realized image at 4/60 second; And carried out normal demonstration of image or the like at 5/60 second; Till need not to use shooting module 103 images acquired (as, the user closes Video chat etc.).
Described in the above whenever to close module 102 backlight, made the example that gets into pellucidity with shooting module 103 corresponding zones at least on the display panels 101 and make shooting module 103 images acquired at a distance from the mode of a frame.Yet, the invention is not restricted to this.According to research, the user thinks that picture links up during picture more than LCD screen 101 shows 30FPS (frame/second), and when the sampling rate of the module 103 of making a video recording be 15FPS when above, its resulting video also links up usually.In addition; According to current technology; Because the refresh rate of LCD Panel 100 is at least 60Hz (that is, a second refresh 60 two field pictures) usually, therefore; As long as can rationally arrange the work timing of display panels 101, module backlight 102 and shooting module 103, display frame that can obtain at an easy rate to link up and continuous collection picture.For example; Can repeat aforesaid operations with every mode at a distance from two frames (that is, shows the time that takies two frames, and gathers the time that takies a frame; In one second, can show 40 two field pictures like this and gather 20 two field pictures); Perhaps, can whenever show after two two field pictures, in the time period of subsequently two frames, carry out the collection (in a second, can show 30 two field pictures like this and gather 30 two field pictures) of image in order to increase the quality of the image that shooting module 103 gathers.In addition, support under the situation of higher refresh rate (like 90Hz) that the ratio that image demonstration and IMAQ can also reasonably be set realizes that the image that more links up shows and IMAQ at LCD Panel 100.
Here; It should be noted that; The image of being gathered by shooting module 103 by the way can be sent to the external device (ED) that is connected with LCD Panel 100 through known transmission path (circuit); And external device (ED) can be through wired or wireless arbitrarily communication mode, and the image that shooting module 103 is gathered sends on the opposing party's (or in many ways) who carries out Video chat or conversation the terminal device, with the image that shows that on this terminal device shooting module 103 is gathered.In addition; For example; Under the situation of the image collecting function of the user test LCD Panel 100 that uses LCD Panel 100; The image of being gathered by shooting module 103 is sent to the external device (ED) that is connected with LCD Panel 100, and will the make a video recording image of module 103 collections of external device (ED) turns back to LCD Panel 100 to show then.Because as stated; Image shows and IMAQ is to carry out discretely; And the demonstration of image and the collection of image are not disturbed mutually, and be therefore, similar with top description; Carry out the time period of IMAQ at shooting module 103; LCD Panel 100 is controlled display panels 101, module backlight 102 and shooting module 103 carrying out the collection of image by aforesaid mode, and in other demonstration time period, normally shows the image of being gathered by shooting module 103 at LCD Panel 100.
Through above-mentioned configuration, on (like, middle position) opening is set in the precalculated position of module 102 backlight, and undersized shooting module 103 is set in opening.Therefore, during carrying out video calling, when the user looked at LCD Panel 100 straight, the user looked at shooting module 103 straight, thereby the user who carries out video calling feels that both sides' sight line is always relative.Therefore, compared with prior art, use user according to the LCD Panel 100 of the embodiment of the invention when carrying out video calling or Video chat, the experience of video calling or chat impression improves.
In addition, when using shooting module 103 images acquired, close entire aphototropism mould 102, make on the display panels 101 to get into pellucidity and use 103 groups of images acquired of shooting mould with shooting module 103 corresponding zones at least.In this case, image shows and IMAQ is carried out (and collection mutually noninterfere of the demonstration of image and image) discretely, and utilizes the light transmission features of display panels 101 to make shooting module 103 can carry out IMAQ.Therefore; The user is when using LCD Panel 100 according to the embodiment of the invention to carry out video calling or chat; Not only can carry out IMAQ; And the user can not perceive the influence of the collection of image to images displayed on the LCD Panel 100 yet, thereby can not influence the susceptibility of user's communication or chat.
The operation that LCD Panel 100 is carried out will be described according to another embodiment of the present invention below.Here, it should be noted that, omitted the description that repeats here because the operation before closing shooting module 103 and opening module 102 backlight is identical, therefore simpler and clearer in order to make instructions with the operation of describing before.
After collection or predetermined collection concluding time that shooting module 103 is accomplished images arrive, and before module 102 backlight was opened, control module 104 can also be controlled display panels 101 and get into opaque states.Particularly, because display panels 101 is when presenting black image, its liquid crystal layer is in light tight state, and therefore, processing unit 104 can make it get into opaque state through sending black images to display panels 101.In addition, the invention is not restricted to this, is that the power supply that can also cut off display panels 101 makes it get into opaque state under the situation of normal black liquor LCD panel (just at making alive not time display panels present black) at display panels 101.
As stated, be in pellucidity with shooting module 103 corresponding subregions at least, can the image such as white image be provided to display panels 101 in order to make on the display panels 101.In this case, after the IMAQ of shooting module 103 is accomplished, and open module 102 backlight and during based on the view data display image that provides from external device (ED), the flicker of image may take place.This be because, according to the working method of display panels 101, (just display panels 101 is based on the mode update image of lining by line scan); Opening when backlight; Display panels 101 is update image line by line, and not being updated as yet in the zone on display panels 101, the image such as white image that inserts before still showing; That is the image that, uses in order to make display panels 101 printing opacities.The view data that this image usually provides based on external device (ED) with display panels 101 and images displayed is different, therefore, the user might perceive institute's images displayed and glimmer.Through before opening module backlight 102, control display panels 101 get into opaque states (as; Insert black image); Even module backlight is opened, because display panels 101 is light tight, therefore being scanned as yet on display panels 101 upgraded in the zone.Show black image, and this to be user's naked eyes can't discover.Therefore, get into opaque state, can avoid the flicker of 100 images displayed of LCD Panel effectively, receive thereby further increase sense of experience of users through before opening module 102 backlight, controlling display panels 101.
Next, with being described in the control method of carrying out according to the LCD Panel 100 of the embodiment of the invention when using shooting module 103 images acquired.Fig. 3 is the process flow diagram according to the control method of LCD Panel 100 execution of the embodiment of the invention.
