Description
LED display technique has advantages of that high brightness, high resolving power show, is applicable to need high brightness and high resolving power to show the occasion of demand, is specially adapted to outdoor demonstration.
LCD and PDP display technique approximately can provide the brightness of 500 nits, and LED display technique can provide much larger than display brightness more than 1000 nits.LCD and PDP display technique can only provide flat pannel display mode, and LED display technique can provide crooked display mode, and can be as required spliced display unit arbitrarily, to form different size, different resolution and difform display screen.The advantage that LED has other display technique to replace in fields such as advertising, entertainment, research and teachings.
Utilize LED display technique to show free stereo image, the constantly fields of research of people always, just because LED display technique is different from LCD and PDP display technique, particularly the arrangement mode of its pixel is not suitable for the application of free 3 D display technology, has therefore hindered the application of free 3 D display technology in LED display.
The present invention proposes a kind of LED large scale freedom stereo display technique, by the redesign of LED display pixel and layout, and the grating of particular design, realized and utilized LED display technique to show free stereo image.
Below in conjunction with accompanying drawing, the present invention is elaborated.
Fig. 1 is the overall description of the LED large scale freedom stereo display technique to the present invention relates to.
The 1st, LED free stereo display unit, each LED free stereo display unit has same dot structure, pixel count and Pixel arrangement mode and display mode.The 2nd, the three-dimensional imaging grating on each free stereo display unit, they can be that cylindrieal lens plate forms, and also can consist of slit grating.The 3rd, computing machine, it is transferred to LED auto-stereoscopic display screen by free stereo image.The 4th, control monitor, its supervisory computer outputs to control signal and the picture signal of LED screen.Three-dimensional imaging grating can be made into the large grating that divides body grating to be spliced into again final display size of the same size of same stereoscopic display unit, also can directly be made into the final the same whole grating of display size
Fig. 2 is the description to LED free stereo display unit.
1 is a LED free stereo display unit.5,6,7 pixels that represent wherein.The arrangement of pixel is: for red pieces pixel, green sub-pixel, blue sub-pixel, form a complete pixel from left to right, then continue with red pieces pixel, green sub-pixel, blue arrangement of subpixels, form successively each complete pixel.11 represent the distance between each complete pixel, namely put distance, and point is apart from fixing, and the distance of the pixel on each free stereo display unit is identical.The arrangement mode of pixel in vertical direction, each provisional capital is the same, from Vertical Square, looks up, and first row is all red pieces pixel, and secondary series is all green sub-pixel, and the 3rd row are all blue sub-pixels, the like.The 12nd, in vertical direction, the distance between two pixels.The 13rd, each free stereo display unit pixel count in vertical direction.The 14th, the pixel count in each free stereo display unit horizontal direction.8,9,10 descriptions is the red pieces pixel of second pixel in the first row horizontal direction, green sub-pixel and blue sub-pixel.The continual arrangement of 15 these pixels of expression is gone down until meet each free stereo display unit sum of all pixels 14 in the horizontal direction.The continual arrangement from top to bottom in vertical direction of 16 these pixels of expression is gone down, until meet whole pixel counts 13 in vertical direction.17 represent the width of each sub-pixel.18 represent the height of each sub-pixel.Because LED display technique is mainly to rely on each little rectangular light emitting diode to form, there are two electrodes at its two ends, there is not irradiative, and in order to be convenient to detailed description of the present invention, we are with the 19 effective luminous height that represent each sub-pixel.In Fig. 2, for clarity, only a light emitting diode has been done to the diagram with welding electrode, and also clearer for what show, what the color of wherein filling was also specially shown has talked compared with other blue sub-pixel a bit.The 20th, each sub-pixel spacing in the horizontal direction, all the spacing between sub-pixel all must keep equating in the horizontal direction.The 21st, each sub-pixel spacing in vertical direction, all pixel spacing in vertical direction all must keep equating.
Fig. 3 illustrates how to obtain a free stereo frame.
23 is objects, and it can be a real object, can be also a digitizing object model generating in computing machine, has a sequence gamma camera to converge on this object, and they are from 24 to 31.These gamma cameras can be real gamma cameras, can be also the gamma cameras in computing machine production of film and TV software.By these gamma cameras, can obtain a sequence image, they are from 32 to 39.The height of these images is 50, and width is 49.Also can represent by pixel, such as gamma camera is high definition gamma camera, 50 concrete numerical value is exactly 1080 pixels, and 49 is exactly 1920 pixels.
First row image pixel in 32 is extracted to the position that is placed into 40, first row image pixel in 33 is extracted to the position that is placed on 41, the like, finally first row image pixel in 39 extracting to the position that is placed on 47, we just obtain free stereo row like this.The sequence that forms successively free stereo row, finally forms free stereo frame.The width of free stereo frame is 48, and is highly 51.If high-definition image, 48 pixel count is 15360 pixels, and 51 pixel count is still 1080.There is variation in the length-breadth ratio of this sampled images, consistent with original image in order to guarantee free stereo frame, need in vertical direction length be amplified to 8 times, and we have finally obtained 8640 pixels in vertical direction.
How Fig. 4 explanation sees the stereo-picture of the demonstration of free stereo frame.
40,41 until 47 be all represent pixel.The 40th, represent the first row first row pixel of the first width figure that first video camera is taken, the 41st, represent the first row first row pixel of the second width figure that second video camera taken, and 47 are the first row first row pixels of the 8th width figure that represents that the 8th video camera is taken.Order row in the past like this.The 53rd, three-dimensional imaging grating, it can be cylindrieal lens plate grating, can be also slit grating, no matter use that grating, in fact can be interpreted as the grating that the pin hole that has been elongated in the vertical direction forms, column mirror grating just can be assembled more light.The 52nd, the light centre of homology of grating, it can be the lens center of column mirror grating, can be also the slit center of slit grating.The 54th, observer's left eye.The 55th, observer's right eye.56 represent the sight line of observer's left eye.57 represent the sight line of observer's right eye.Can find out, observer's left eye can only be seen the pixels such as 41,48,53,59; And right eye can only be seen the pixels such as 40,47,60,61.In other words, left eye can only be seen the image that second gamma camera taken, and right eye can only be seen the image that first gamma camera is taken.If at this moment observer is moved to the left in the horizontal direction, left eye can be seen the 3rd width image, fourth officer image successively, until the 8th width image; And right eye also can be seen the second sub-picture, the 3rd width image successively, until the 7th width image.What at this moment observer saw is the sequence image with different parallaxes, has therefore obtained stereoscopic vision, and has obtained certain visual angle.Observer continues to be moved to the left again, will experience once anti-phase, when left eye sees 47, and right eye sees that generation in 46 o'clock is once anti-phase, because at this moment left eye has been seen the figure that first gamma camera is taken, and right eye has been seen the 8th figure that gamma camera is taken, at this moment not only parallax is contrary just, and be very large anti-phase parallax, it is very uncomfortable that observer can feel, this is the intrinsic shortcoming of freedom tridimensional imaging technique.Yet this process is of short duration, because as long as cross over after this pixel groups, it is normal that parallax sequence just becomes again.The 63rd, grating, to the distance of display screen, is said accurately, is that grating is to the distance between display pixel.The 64th, the cycle of grating, be also pitch, with the term of grating specialty, can be called the grid stroke number of per inch, with LPI, describe.The 62nd, the interocular distance of human eye, is approximately 6.5 centimetres.
Fig. 5 illustrates the basic structure of a LED free stereo display unit.
70 is LED free stereo display units, and 78 represent number of pixels for vertical height simultaneously, and 79 represent Horizontal number of pixels for horizontal width simultaneously.The 71st, grating, can be that column mirror grating can be also slit grating, and grating can slant setting, to be used for eliminating contingent Moire fringe, also can vertically place, angle 81 can regulate, and this angle must match with free stereo frame certainly.The 80th, the cycle of grating, the 72nd, grating 71 is fixed on to the picture appearance effect that LED display unit 70 forms above.LED image presents by grating, and distinguishes generation stereoscopic vision by the binocular parallax of human eye.The 82nd, grating arrives the distance of LED display.The 73rd, the driving circuit box of LED display.The 76th, the driving circuit of LED display.The 77th, picture signal and the power supply of input LED display.
Grating can be made of metal, is so not only convenient to guarantee Precision Machining, but also can adapt to LED, shields the reliability while applying under high temperature and low temperature environment.Adopt metal to make the weight that grating can also effectively alleviate grating, be also convenient to Installation and Debugging.Another significant advantage is that employing metal grating can be eliminated More's interference effectively, because the back side of metal grating can be not reflective, therefore also just can not interact and formation More interference with LED screen.Adopt effectively controlled working precision of laser technology processing metal grating.Grating also can be made by nonmetallic materials, although its temperature characterisitic is be not as good as metal grating, in indoor application, can meet the demands completely.Adopt nonmetallic materials to make grating, its weight can be lighter, is more convenient to Installation and Debugging.Grating also can be made of rope, selects the rope of certain diameter and its tension that keeps at a certain distance away is arranged to be also made into the well grating of practicality of effect, and the part that has rope is dark fringe part, and between rope and rope, is exactly transparent stripe part.Grating also can be used film production, and this is a kind of large scale preparing grating method that cost performance is higher, and because film grating is realized by laser photo-typesetting mode, its precision is high, and the density of dark fringe also can do very high, there is good contrast-response characteristic.Because film intensity is very high, therefore film grating can directly be used as grating curtain, film grating also can be bonded on acrylic or sheet glass and be made by ultraviolet glue, the Flatness of making is like this good, impact resistance is strong, but weight is very large, especially when the width of screen is when more than ten meters, utilize the grating that the method for glass or acrylic adhesive sheet is made to bring very large difficulty to Installation and Debugging.No matter, for split type grating or monoblock type grating, the periphery of grating and central authorities can arrange reinforcement, and its diameter is very little, and they are placed in the dark fringe place of grating, therefore can not affect subjective vision precision and stereopsis effect.Grating also can be made of cylindrieal lens plate, and just because screen size is large, grating pitch is larger, makes such large size column mirror grating, and its cost performance is not very desirable.
84 and 84 is structural drawing of reinforcement, and they are surrounded grating in the outside of each display unit, then in centre, several reinforcements are set.Grating is fixed on LED display unit by metal support or plastic stent.Because slit must guarantee every eyes and can both see accurately the view of oneself, so LED display unit can not be installed light shield again.Whole light emitting diodes is all wanted exposed being welded on substrate.
Fig. 6 is the large scale LED auto-stereoscopic display screen that utilizes LED free stereo display unit to be spliced into.The width of the 79th, LED free stereo display unit, 78 is the height of LED free stereo display unit, the 90th, the spliced screen of LED free stereo display unit is wide, the 91st, the spliced screen of LED auto-stereoscopic display screen is high.Driving circuit cabinet and the electronic drive circuit of the 92, LED auto-stereoscopic display screen, the 93rd, grating.Because grating grating is with Existential Space distance between LED display unit, so the effect of ventilation and heat is good.In actual applications, LED free stereo display unit is smaller, forms larger free stereo display unit and shields, then be spliced into final large scale LED auto-stereoscopic display screen by these screens by the LED free stereo display unit screen of some.
Fig. 7 is a kind of whole grating allocation method.When the width dimensions of grating is during 5 meters of left and right, adopt whole grating still to have many good qualities.The 110th, LED display, has been spliced by polylith LED screen.The 111st, fix 110 metal frame, this frame comprises floor stand or backrest, to facilitate by the stable placement of this LED large size panel on the ground or be suspended on body of wall.The 113rd, whole grating, the 112nd, fix the metal frame of this integral body grating, 113 and 112 overall dimensions is all more than or equal to 111 size, 113 can use film preparing grating, can make of rope, also can make by metal or nonmetallic materials, no matter with which kind of material, make, this grating is all fixed on metal edge frame 112.112 have floor stand or backrest, to guarantee on the ground of the front end that is placed on LED display that this grating can be stable, or hang on the front end of LED display and are fixed on body of wall, also can be directly fixed on 111, form one.113,112 with 110 without any contacting, between 113 and 110, only have air dielectric.Be fixed wtih 112 of grating and can be connected to and on 111, form an integral body, and then fix on the ground or body of wall on.Because large-scale film grating also will splice conventionally, 115 to 118 methods of having illustrated this jointing grating.The 115th, the film grating before splicing, draws in the drawings three blocks of such film gratings and completes the state before splicing, and three blocks of gratings cut along 117 and 118 direction split, notice that this line of cut must be the medium line of the dark fringe of grating.The 116th, the grating after having spliced, because splicing completes at dark fringe place, therefore can't see these seams in grating the place ahead.
If make grating with rope, on 112, must settle according to metal locating slot or the pilot hole of the design of grating cycle, rope repeatedly passes through these locating slots or Kongzui end form becomes grating.Utilize rope to make grating and can not be subject to size restrictions, weight is also very light, is a kind of very practical method.The diameter of rope is exactly the width of the dark fringe of grating, and the center distance between rope and rope has formed the cycle size of grating, and the distance between two dark fringes has formed transparent stripe spacing.
Fig. 8 is the grating of a kind of capable of regulating grating pitch or grating cycle, slit width, grating angle.
The 134th, the strip connecting link of equal length, in the middle of it and two ends all have aperture, these apertures connect into continuous rhombus array by close-fitting metal shaft according to the mode in figure, because hole can be rotated between centers, therefore when effectively in 140 directive effect, the shape of all rhombuses can zoom in or out along horizontal direction, both with the distance between the center node of whole rhombuses of 125 expressions, can become large or diminish with the effect of putting forth effort 140.The 121st, there are certain width and the lenticular lenses being made into by metal or nonmetallic materials that can rotational angle, 127 in figure is at the width of facing the grating of seeing in grating situation, this width can change along with the rotation of lenticular lenses.125 have represented the center node of whole diamond structures, 123 and 124 have represented the summit of whole diamond structures, small circle wherein represents that they are to be all connected with the axle penetrating in hole by the hole on connecting link, in order to guarantee that figure's is clear, only with part circle, represent these holes and axle, the hole that other position is same and axle just do not draw with such circle.The upper part of Fig. 9, illustrates that, under 140 effect, grating presents the cycle 126, and the lower part of Fig. 9 illustrates that, under 140 effect, grating presents the less cycle 126, has illustrated that this grating is to adjust easily the grating cycle by adjusting 140.Whole rhombus center nodes are fixed in metal sliding slot 127 or 128, if whole moves left and right 127 or 128, chute will drive whole diamond structure along continuous straight runs to move, so just can adjust easily the pitch angle of grating, to proofread and correct because LED spells screen processing and spells the error that screen is installed appearance.Change the angle of lenticular lenses with respect to the angle of LED screen, just can adjust easily the slit width of slit grating, when lenticular lenses 121 is parallel to LED display placement, the width of slit is minimum, is 130.Rotate after an angle, it is large that slit becomes, and is 131.During 90-degree rotation,, when lenticular lenses is vertically placed with respect to LED display, slit width is maximum, directly display plane is visual, the compatibility that has realized plan view image and stereoscopic image shows, controls the rotation of lenticular lenses and can use Electric Machine Control, also can use easily magnet control.
