By optimization, the LCD is provided with vertical pixels, the raster comprises a set of micro lens array and is made of the material with high light transmittance ratio suited to the screen of the LCD, and the angular field of view in the auto imaging and stereo display apparatus. With this utility model, the observer could see clear stereo effect in the angle range of about one hundred and twenty degrees in front of the LCD without wearing stereo spectacles or other any secondary observation apparatus, thereby removing sixty percents of the mole veins.
Description
Technical field
The utility model relates to a kind of automated imaging stereoscopic display device, more specifically relates to a kind of automated imaging stereoscopic display device that utilizes oblique raster.
Background technology
In the process of stereo display technique development, the various products that need utility appliance just can watch stereoeffect have successively appearred, as the 3D helmet (HMD, two small-sized two-dimentional LCD are placed two eyes the place aheads respectively, the image that produces amplifies by optical system), 3D polaroid glasses (polarized lenses comes the image branch of the left and right sides and watches), shutter glasses (alternately watch by right and left eyes, block the image that right and left eyes is watched at a terrific speed respectively), the product that is updated gradually substitutes these products owing to carry that inconvenience and portioned product can only be applicable to that a certain class people watches.What occur subsequently a kind ofly need not the display that utility appliance is watched stereopsis, what utilize is the wavelength selective filter technology, it is by being positioned at the light filter of screen forefront, selectively image information being sent on the screen of display, presenting stereoeffect with this.The drawback of this method is that owing to filtered most optical elements, the brightness of image has been reduced greatly; In addition,, on screen, can produce serious reflected light, influence the demonstration effect of image as minute surface because the transparency height has blocked nearly 3/4 pictorial element.
Therefore, be necessary to design the automated imaging stereoscopic display device that a kind of viewing angle is broad more, demonstrate better effects if in fact.
The utility model content
The utility model purpose is to provide a kind of automated imaging stereoscopic display device that can realize broader viewing angle and can remove a large amount of moles of lines.
To achieve these goals, the automated imaging stereoscopic display device of oblique raster that utilizes of the present utility model comprises:
One LCD;
One overlays the grating on the described LCD, described grating along described LCD vertically with a specific angle tilt, the size of described grating is identical with described LCD, and each lens in the described grating are accurately aimed at by the mole interferometry with each pixel of described LCD.
Preferably, described LCD is the vertical pixel LCD, and described grating is made of one group of microlens array.
The employed grating of the utility model by the high transmission rate material that is complementary with liquid crystal display equipment screen for example polymethylmethacrylate make.
Preferably, the visible angle scope of described automated imaging stereoscopic display device is the 0-120 degree.
By the utility model, the beholder need not to wear anaglyph spectacles or other any auxiliary evaluation equipments just can be watched stereoeffect clearly in the 120 degree visual angles about LCD the place ahead, and has removed 60% mole line.
Description of drawings
Below, will be described in more detail embodiment of the present utility model in conjunction with the accompanying drawings, wherein:
Fig. 1 shows the side view according to automated imaging stereoscopic display device of the present utility model;
Fig. 2 shows the stereographic map of the employed grating of the utility model;
Fig. 3 shows the cross section detailed maps that grating combines with LCD;
Fig. 4 shows grating slope and overlays synoptic diagram on the LCD;
Fig. 5 shows the imaging synoptic diagram of different viewing location.
Embodiment
Go out as shown in Figure 1, comprise a LCD 1 according to automated imaging stereoscopic display device of the present utility model, this LCD 1 for example can be the vertical pixel LCD of any suitable size that can buy on the market.The grating 2 that is made of one group of microlens array is placed on the horizontal panel of described LCD 1 with being tilted, and the size of described grating 2 is identical with described LCD 1, the refraction action of scioptics like this, and display element will be in sight.In order to realize autostereoscopic imaging, described grating 2 vertically tilts with a special angle along LCD 1, and each lens in the described grating 2 are accurately aimed at by the mole interferometry with each pixel of described LCD 1, reflect in the horizontal direction to guarantee 2 on this grating.
Fig. 2 shows the stereographic map of the employed grating 2 of the utility model, and wherein microlens array is arranged in parallel with a specific angle of inclination, and each is different according to different liquid crystal display type for the pitch of grating 2 and related datas such as thickness.Described grating 2 is made by the material that is complementary with liquid crystal display equipment screen usually, but have good light transmittance and cutting as long as guarantee it, for example can select for use polymethylmethacrylate to make grating, even so that guarantee this grating 2 with after LCD 1 combines or ambient temperature also can keep and the pixel of LCD and aiming at of optical elements when changing.
Fig. 3 shows the cross section detailed maps that grating 2 combines with LCD 1.Described as we can see from the figure display screen comprises Polarizer 3, first glass substrate 4, first colored filter 5, liquid crystal cells 6, second colored filter 7, second glass substrate 8 and following Polarizer 9 successively, and described grating 2 is placed on the Polarizer 3.Can send the beholder to by the refraction and the diffraction image that liquid crystal cells is shown of the microlens in the grating 2 in different viewing location (source of light path), thereby make the beholder can watch three-dimensional image effect in different positions.
Can clearly show that in Fig. 4 grating 2 overlays on the LCD 1 with a specific angle with being tilted.Because covering, the black that the pel spacing of LCD 1 produces to cause an appearance mole line phenomenon, display device of the present utility model is by covering black the conversion spread apart and make between the picture more smooth and easy this black covering of hiding that becomes, while is by the refraction and the diffraction of the microlens in the grating 2, black between the pixel of LCD 1 can be covered refraction and fall, thereby what make that the user feels that they see is " continuous object " rather than a series of picture of beating.As user during in display the place ahead move left and right, he will be all the time can see some but in fact ND black covers, thereby removed the mole line effectively, the stereoeffect of picture also can be enhanced, and the visible angle scope of this display device also expands to the 0-120 degree simultaneously.
Fig. 5 shows according to the imaging synoptic diagram of display device of the present utility model in different viewing location.Can see the slightly different picture of two width of cloth (the 1st, 2 width of cloth picture) on the position of straight line A, brain makes up this two width of cloth picture, thereby can produce the effect of stereo-picture.Arrived when user's moving-head on the position of straight line B, sight line can be seen the 7th width of cloth and the 8th width of cloth picture, and the 5th width of cloth and the 6th width of cloth picture can enter into the visual angle on the C position.Like this, in the process that the user moves, the conversion between the picture is progressive, so just can obtain the effect of being fade-in fade-out of picture, thereby obtains a series of pictures continuous rather than that beat.
Automated imaging stereoscopic display device of the present utility model not only can present stereo-picture clearly, more can remove 60% mole line, and simultaneously its viewing angle also increases to 120 degree, thereby provides more good three-dimensional imaging effect for the user.
