主要是依靠每个小的呈矩形的发光二极管构成的,其两端有两个电极,那里是不会发光的,为了能够便于对本发明的详细描述,我们用19表示每个子像素的有效发光高度。 Mainly rely on each small rectangular light emitting diode, which ends with two electrodes, there is not emitting light, in order to facilitate the detailed description of the invention, we use 19 represents the effective height of each sub-pixel emission . 在图2中,为了清晰起见,只对一个发光二极管做了带有焊接电极的图示,而且为了显示的更清 In FIG. 2, for clarity, only one LED been illustrated with welding electrodes, and in order to show a more clear

楚,对其中填充的颜色也特意显示的较其它蓝子像素谈了些。 Chu, of which the color of the fill has purposely display than other blue subpixel talk a bit. 20是 20 is

每个子像素在水平方向上的间距,全部子像素之间的间距在水平方向 Each sub-pixel pitch in the horizontal direction, the spacing between all of the sub-pixels in the horizontal direction

上都必须保持相等。 Must remain equal on. 21是每个子像素在垂直方向上的间距,全部像素在垂直方向上的间距都必须保持相等。 21 each sub-pixel pitch in the vertical direction, the entire pixel pitch in the vertical direction must remain equal. 图3是说明如何获得一个自由立体帧的。 FIG 3 is a diagram illustrating how to obtain a stereoscopic frame.

23是一个物体,它可以是一个真实的物体,也可以是一个在计算机中生成的数字化物体模型,有一个序列摄象机会聚到这个物体上,它们是从24到31。 23 is an object, it can be a real object, the digital object may be a model generated in the computer, there is a sequence of the object focused onto the camera, they are from 24 to 31. 这些摄象机可以是真实的摄象机,也可以是计算机影视制作软件中的摄象机。 These cameras can be a real camera, film and television production can also be a computer software in the camera. 通过这些摄象机,可以获得一个序列图像, 它们是从32到39。 These cameras can be obtained a sequence of images, which are from 32 to 39. 这些图像的高度为50,宽度为49。 The height of the image is 50, a width of 49. 也可以用像素来表示,比如摄象机是高清摄象机,则50的具体数值就是1080个像素,而49就是1920个像素。 May be represented by a pixel, such as high-definition camera is a video camera, is the particular value of the 50 pixels 1080, and 1920 is 49 pixels.

将32中的第一列图像像素提取出来放置到40的位置,将33中的第一列图像像素提取出来放置在41的位置,依次类推,最后将39中第一列图像像素提取出来放置在47的位置,这样我们就得到一个自由立体列。 The first column of the image pixels placed in positions 32 extracted 40, will be extracted is placed in position 41 of the first column of pixels in the image 33, and so on, and finally the extract is placed in the first column of pixel 39 47 position, so that we get a free three-dimensional columns. 依次形成自由立体列的序列,最终形成自由立体帧。 Sequentially forming sequences of stereoscopic columns, forming autostereoscopic frame. 自由立体帧的宽度是48,而高度是51。 Stereoscopic frame width 48, and height 51. 如果是高清图像,则48的像素数为15360个像素,而51的像素数仍为1080。 If the high-definition image, the pixel number 48 is 15360 pixels, and the number of pixels 51 is still 1080. 这样图像的长宽比率出现 Such aspect ratio of the image appears

了变化,为了保证自由立体帧同原有图像相一致,需要在垂直方向上 Change, in order to ensure freedom perspective consistent with the original image frame, it is necessary in the vertical direction

将长度放大8倍,我们最终获得了在垂直方向上有8640个像素。 8 times the length of the amplification, we finally obtained has 8640 pixels in the vertical direction. 图4说明如何看到自由立体帧的显示的立体图像。 See FIG. 4 illustrates how a stereoscopic image frames autostereoscopic display. 40、 41直到47都是代表像素的。 40, 41 until 47 are representative pixels. 40是代表第一个摄像机拍摄的第一幅图的第一行第一列像素,41是代表第二个摄像机拍摄的第二幅图的第一行第一列像素,而47是代表第八摄像机拍摄的第八幅图的第一行第一列像素。 FIG 40 is a first imaging camera represents the first pixel of the first row and first column, the second web of FIG. 41 is representative of a second camera photographing a first row and first column of pixels, and 47 represent the eighth the first line of cameras eighth figures of the first column of pixels. 这样顺序排过去。 The last row in this order. 53是立体成像光栅,它可以是柱镜板光栅,也可以是狭缝光栅,无论用那种光栅,其实都可以理解为在垂直方向被拉长了的针孔构成的光栅,柱镜光栅只是可以会聚更多光线。 53 is a stereoscopic imaging grating, it may be a lenticular sheet grating slit grating may be, that no matter grating, in fact, be understood that the raster is elongated in the vertical direction as a pinhole configuration, only lenticular You may converge more light. 52是光栅的光线透射中心,它可以是柱镜光栅的透镜中心,也可以是狭缝光栅的狭缝中心。 52 is a light transmittance of the center of the raster, it may be a lenticular lens center may be the center of a slit grating slit. 54是观察者的左眼。 54 is a viewer's left eye. 55是观察者的右眼。 55 is the observer's right eye. 56表示观察者左眼的视线。 56 represents a line of sight of the observer's left eye. 57表示观察者右眼的视线。 57 represents the right eye of the observer line of sight. 可以看出,观察者左眼只能看到41、 48、 53、 59等像素;而右眼只能看到40、 47、 60、 61等像素。 As can be seen, the observer can only see the left 41, 48, 53, 59 and other pixels; and the right eye can only see 40, 47, 60, 61, etc. pixels. 换句话说,左眼只能看到第二个摄象机拍摄的图像,而右眼只能看到第一个摄象机拍摄的图像。 In other words, the left eye only sees the image taken by the second cameras, and the right eye only sees the image taken by the first camera. 如果这时观察者在水平方向向左移动,则左眼会依次看到第三幅图像、第四副图像,直到第八幅图像;而右眼也会依次看到第二副图像、第三幅图像,直到第七幅图像。 If at this time the observer moves to the left in the horizontal direction, the left eye will see a third order images, a fourth sub-images until the eighth images; and the right eye will see the second sub image sequentially, a third images, images until the seventh. 这时观察者看到的是具有不同视差的序列图像,因此获得了立体视觉,并且获得了一定的视角。 In this case the viewer sees is the sequence of images having different parallaxes, thereby obtaining the stereoscopic vision, and a certain degree of viewing angle. 观察者继续再向左移动,就会经历一次反相,即当左眼看到47,而右眼看到46时发生一次反相,因为这时左眼看到了第一个摄象机拍摄的图,而右眼看到了第八个摄象机拍摄的图,这时不仅视差恰好是相反的,而且也是 Continues to move further to the left the viewer will experience a reverse phase, i.e. when the left eye 47, and a right eye occurs when the inverter 46, because when the left eye sees the view of a camera recorded, right eye to see the eighth camera image shot, this time not only the disparity is exactly the opposite, but also

很大的反相视差,观察者会感觉很不舒服,这是自由立体成像技术的固有缺憾。 Great inverting the disparity, the viewer will feel uncomfortable, which is an inherent defect free three-dimensional imaging technology. 然而,这个过程是短暂的,因为只要跨越这个像素组后, 视差序列就又变的正常了。 However, this process is short-lived, because as long as this group of pixels across, the disparity sequence and again become normal. 63是光栅到显示屏的距离,准确的说, 63 is a raster-to-screen distance, to be exact,

是光栅到显示像素之间的距离。 Is the distance between the raster display pixel. 64是光栅的周期,也叫栅距,用光栅专业的术语可称作每英寸的光栅线数,用LPI描述。 Is the period of the grating 64, also called the pitch, the raster professional terms may be referred to the number of raster lines per inch, described by LPI. 62是人眼的瞳孔间距,大约为6.5厘米。 62 is a pupil of the eye spacing of about 6.5 cm.

图5说明一个LED自由立体显示单元的基本结构。 Figure 5 illustrates the basic structure of a stereoscopic display LED unit. 70是一个LED自由立体显示单元,78为垂直高度同时表示像素数目, 79为水平宽度同时表示水平像素数。 LED 70 is a stereoscopic display unit 78 it is also said that the height of the vertical number of pixels, while 79 denotes a horizontal width of the horizontal pixel number. 71是光栅,可以是柱镜光栅也可以是狭缝光栅,光栅可以倾斜放置,以用来消除可能发生的莫尔干涉条纹,也可以垂直放置,夹角81是可以调节的,当然这个夹角必须同自由立体帧相匹配。 71 is a grating, the grating may be a lenticular may be slit grating, the grating can be tilted, in order to eliminate moire fringing is likely to occur, may be placed vertically, the angle 81 is adjustable, the angle of course It must match autostereoscopic frame. 80是光栅的周期,72是将光栅71固定在LED显示单元70上面后形成的图像外观效果。 80 is the grating period, the grating 72 is fixed to the LED 71 displays an image formed after the appearance upper unit 70. LED图像通过光栅呈现出来,并通过人眼的双眼视差辨别产生立体视觉。 LED image presented by a grating, and generating by a binocular parallax stereoscopic vision of the human eye to distinguish. 82是光栅到LED 显示屏的距离。 82 is a raster distance to the LED display. 73是LED显示屏的驱动电路盒。 LED drive circuit 73 is a display box. 76是LED显示屏的驱动电路。 76 is a driving circuit of the LED display. 77是输入LED显示屏的图像信号和电源。 77 is an input image signal and a power LED display. 光栅可以用金属制作,这样不仅便于保证精密加工,而且还可以适应LED屏在高温和低温环境下应用时的可靠性。 Grating may be made of metal, so that not only easy to ensure the precision machining, but also can accommodate an LED screen application reliability at high temperature and low temperature environment. 采用金属制作光栅还可以有效的减轻光栅的重量,也便于安装调试。 Is made of metal grating may also be effective to reduce the weight of grating, also facilitates installation. 另一个显著的优点是, 采用金属光栅会有效地消除莫尔千涉,因为金属光栅的背面不会反光,因此也就不会同LED屏相互作用而形成莫尔干涉。 Another significant advantage is the use of a metal grating will effectively eliminate moire intervention, since light is not reflected back metal grating, therefore, will not interact with the LED screen to form a Moire interference. 采用激光技术加工金属光栅可以有效控制加工精度。 Metal grating laser processing technology can effectively control precision. 光栅也可以用非金属材料制 The grating may be made of non-metallic material

作,虽然其温度特性不如金属光栅好,但在室内应用是完全可以满足要求的。 For, although it was not as good temperature characteristics of metal grating, but in indoor applications fully meet the requirements. 采用非金属材料制作光栅,其重量可以更轻,更加便于安装调试。 Non-metallic materials grating, which can be lighter weight, easier installation. 光栅也可以用绳子制作,选择一定直径的绳子并使其间隔一定距离拉紧排列也可以制作成效果很好的实用的光栅,有绳子的部分是暗条纹部分,而绳子与绳子之间就是透明条纹部分。 Grating may also be made with a rope, rope and a diameter selected so that a distance from the tightening arrangement may also be made into a very practical effect of the grating, there is a dark stripe portions of the rope portion between the rope and the rope is transparent fringe portion. 光栅也可以用胶片制作,这是性价比较高的一种大尺寸光栅制作方法,由于胶片光栅是通过激光照排方式实现的,其精度极高,且暗条纹的密度也可以做的很高,具有很好的对比度特性。 Grating may be produced on film, which is the higher cost of a large-size raster manufacturing method, since the film by the grating of the laser phototypesetting manner, high precision, and the density of dark stripes may be made high, having excellent contrast characteristics. 由于胶片强度很高,因此胶片光栅可以直接作为光栅幕使用,胶片光栅也可以通过紫外胶粘结在亚克力或平板玻璃上制成,这样制作的光栅平整度好,耐冲击力强,但重量很大,尤其当屏幕的宽度在十米以上时,利用玻璃或亚克力粘结胶片的方法制作的光栅会给安装调试带来很大的困难。 Because of the high film strength, the film can be directly used as the grating using a grating screen, the grating film may be formed on a flat glass by UV or acrylic adhesive junction, making such a grating good flatness, impact resistance and strong, but very weight large, especially when the width of the screen when than 10 meters, using the grating glass or acrylic adhesive sheet made by the method of installation will bring great difficulties. 无论对于分体式光栅还是整体式光栅,光栅的周边和中央都可以设置加强筋,其直径很小,它们安置在光栅的暗条纹处,因此不会影响主观视觉精度和立体视效果。 For either of stiffened split grating or grating integral, peripheral and central rib grating can be set, which is small in diameter, they are disposed at the dark stripe of the grating, it will not affect the accuracy and subjective visual stereoscopic effect. 光栅也可以用柱镜板制作,只是由于屏幕尺寸大,光栅栅距较大,制作这样的大尺寸柱镜光栅,其性价比不是很理想。 Grating may also be used lenticular plate, but due to the large screen size, a larger grating pitch, to make such a large lenticular, whose cost is not very satisfactory.

84和84是加强筋的结构图,它们在每个显示单元的外面将光栅包围起来,再在中间设置数条加强筋。 84 and 84 is a configuration diagram of a rib, which surround the grating on the outside of each display unit, and then set the number of reinforcing ribs in the middle. 光栅通过金属支架或塑料支架固定在LED显示单元上。 Grating bracket on the LED display unit by a metal or plastic bracket. 因为狭缝必须保证每只眼睛都能够准确的看到自己的视图,因此LED显示单元不能再安装遮光罩。 Because the slits must ensure that each eye can see accurately their view, the LED display unit can not be installed hood. 全部的发光二极管都要裸露焊接在基板上。 All of the light emitting diode to be soldered on the exposed substrate.

图6是利用LED自由立体显示单元拼接成的大尺寸LED自由立体显 FIG 6 is a stereoscopic display unit using LED spliced ​​into the large-size LED autostereoscopic significant

示屏。 Display screen. 79是LED自由立体显示单元的宽度,78为LED自由立体显示单元的高度,90是将LED自由立体显示单元拼接后的屏宽,91是将LED自由立体显示屏拼接后的屏高。 79 is the autostereoscopic display width LED unit 78 LED autostereoscopic display unit height, the LED 90 is the autostereoscopic display screen width splicing unit 91 is high after the LED screen autostereoscopic display mosaic. 92是LED自由立体显示屏的驱动电路机箱和电子驱动电路,93是光栅。 92 is the autostereoscopic display LED driving circuit of the electronic chassis and the drive circuit, 93 is a grating. 由于光栅光栅同LED显示单元之间存在空间距离,因此通风散热的效果是良好的。 Since the gratings with a distance there is a space between the LED display unit, and therefore the heat dissipation effect is good. 在实际应用中,LED自由立体显示单元是比较小的,由一定数量的LED自由立体显示单元屏构成较大的自由立体显示单元屏,再由这些屏拼接成最终的大尺寸LED自由立体显示屏。 In practice, LED autostereoscopic display unit is relatively small, a certain number of LED stereoscopic display unit screen autostereoscopic display constituting a large screen unit, and then by splicing the screen into the final large-sized LED display autostereoscopic .

图7是一种整体光栅安置方法。 FIG 7 is a grating disposed integrally method. 当光栅的宽度尺寸在5米左右时,采用整体光栅还是有很多优点的。 When the width dimension of about 5 meters of the grating, the grating with the overall still has many advantages. IIO是LED显示屏,已经由多块LED 屏拼接完成。 IIO LED display, LED has been completed by the plurality of screen display. 111是固定110的金属框,该框包括落地支架或背架, 以方便将该LED大尺寸屏稳定的放置在地面上或悬挂在墙体上。 111 is a fixed metal frame 110, the frame or the back frame comprising a floor stand, to facilitate the stable large-size LED screen placed on the floor or hung on the wall. 113 是整体光栅,112是固定该整体光栅的金属框,113和112的整体尺寸均大于或等于111的尺寸,H3可以用胶片光栅制作,可以用绳子制作,也可以用金属或非金属材料制作,无论以何种材料制作,该光栅均固定在金属边框112上。 113 is an entire grating, the grating 112 is integrally fixed to the metal frame 113 and the overall dimensions are greater than or equal to 112 111 size, H3 can be made with a grating film may be made with a rope may be made from metal or non-metallic material , whatever builder, this grating are fixed to the metal frame 112. 112有落地支架或背架,以保证该光栅可以稳定的放置在LED显示屏的前端的地面上,或悬挂于LED显示屏的前端并固定于墙体上,也可以直接固定于111上,形成一体。 112 or the back frame with a floor stand, to ensure that the grating can be stably placed on the ground in the front end of the LED display, LED display, or hung on the front end and fixed to the wall, may be fixed directly to the 111, are formed one. 113、 112和110没有任何接触,113和110之间只有空气介质。 113, 112 and 110 not be in any contact between the medium of air, 113 and 110. 固定着光栅的112可以连接到111上形成一个整体,然后再固定在地面上或墙体上。 112 fixed grating 111 can be connected to form a whole, and then fixed on the ground or on the wall. 由于大型的胶片光栅通常也要拼接完成,115至118示意了这种拼接光栅的方法。 Since usually have large grating film splicing is completed, 115-118 illustrate this method of splicing grating. 115是拼接前的胶片光栅,在图中画出三块这样 115 is a grating film before splicing, three shown in the drawings so

的胶片光栅完成拼接前的状态,三块光栅沿着117和118的方向分体切割,注意这个切割线必须是光栅的暗条纹的中间线。 State before completion grating film splicing, three separate gratings 117 and 118 in the direction of cutting, the cutting wire must be noted that the center line of the dark stripe of the grating. 116是拼接完成后的光栅,由于拼接是在暗条纹处完成的,因此在光栅前方是看不到这些接缝的。 Grating 116 after completion of splicing, the splicing is done because the dark stripes, and are therefore not see the grating in front of the seam.

如果用绳子制作光栅,则在112上必须安置按照光栅周期设计的金属定位槽或定位孔,绳子反复穿越这些定位槽或孔最终形成光栅。 If making a grating with a rope, metal must be disposed in accordance with the positioning grooves or positioning holes on the grating period 112 is designed, the rope is repeatedly through these holes or the positioning grooves eventually forming a grating. 利用绳子制作光栅可以不受尺寸限制,重量也很轻,是一种很实用的方法。 The rope can be made using a raster size is not limited, and light in weight, is a very practical method. 绳子的直径就是光栅的暗条纹的宽度,绳子与绳子之间的中心间距构成了光栅的周期尺寸,两个暗条纹之间的距离构成了透明条纹间距。 The spacing between the center of the width is the diameter of the rope and the rope of the rope dark stripe grating period constitutes the grating size, the distance between the two constitutes a dark stripe transparent fringe spacing. 图8是一种可调整光栅栅距或光栅周期、狭缝宽度、光栅角度的光栅。 FIG 8 is an adjustable grating period or grating pitch, the width of the slit, the grating angle of the grating. 134是等长度的条状连接杆,其中间及两端都开有小孔,这些小孔通过紧密配合的金属轴按照图中的方式连接成连续的菱形阵列,由于孔可以在轴间转动,因此当有力在140方向作用时,所有菱形的形状会沿着水平方向放大或縮小,既以125表示的全部菱形的中心结点间的距离会随着力140的作用而变大或变小。 134 is a strip of equal length connecting rod, and wherein between both ends opened holes which are connected as shown in a continuous manner by a diamond-shaped array of close fitting metal shaft due to the rotation between the shaft hole may be, Thus, when a force acts in the direction 140, all rhombic shape is enlarged or reduced in the horizontal direction, both the distances between the central node of all diamond 125 would represented as force 140 becomes larger or smaller. 121是有一定宽度且可以转动角度的用金属或非金属材料制作成的光栅片,图中的127是在正视光栅情况下看到的光栅的宽度,该宽度会随着光栅片的转动而改变。 121 may have a certain width and the angle of rotation or non-metallic material into the lenticular sheet, the figure 127 is a front view seen raster width of gratings, the width of the lenticular sheet with rotation will vary . 125表示了全部菱形结构的中心结点,123和124表示了全部菱形结构的顶点,其中的小圆圈表示它们全部是通过连接杆上的孔和穿入孔中的轴相连接的,为了保证图的清晰,只用部分圆圈表示这些孔和轴, 其它部位同样的孔和轴就没有用这样的圆圈画出。 125 represents a central node of all diamond structure, 123 and 124 represent all the vertices of the rhombus structure in which all of the small circle and the hole penetrating through the shaft hole connecting rod is connected, in order to ensure FIG. the clear circles represent only part of these holes and the shaft hole and the other parts of the same axis drawn with no such circle. 图9的上部分,说明在140的作用下,光栅呈现出周期126,图9的下部分,说明在140 Upper portion of FIG. 9, explained under the action of 140, showing the grating period 126, the lower portion of FIG. 9, 140 described in
