Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by embodiment:
As Figure 1-Figure 4, in the present invention all circuit board LED lamp pearl arrange all must with many viewpoints program strict conformance that will adopt.According to the arrangement of sub-pixel, there are various possibilities, taking 8 viewpoint programs as example, as shown in Figure 1, as shown in Figure 2, upper right arranged askew as shown in Figure 3 for upper left arranged askew for homeotropic alignment, these three kinds of arrangements are single file circulation, also have the arrangement that adopts two row circulations, and Fig. 4 for example understands this arrangement.
As shown in Figure 5, Figure 6, multi-viewpoint three-dimensional shows that the top of LED special lens 1 housing is protruding cambered surface 2, and bottom surface is horizontal quadrilateral, and the side 3 of housing is formed by connecting by four quadrilaterals.As shown in Figure 6, Figure 7, also can be provided with the projection 4 of conveniently adhering to use in the bottom surface of special lens 1, projection 4 quantity can determine as required, here be exemplified as three to (referring to Fig. 8 and Fig. 9), be distributed in symmetrically and evenly on bottom surface.
In the time of outdoor application, in order to prevent ponding, it is trapezoidal special lens 1 can being made to side-looking, as shown in figure 10, the side-looking that also can make is as shown in figure 11 quadrilateral, and top is the gradient with certain angle of declination, and bottom is still horizontal, as shown in figure 11.
As shown in Figure 11, Figure 12, Figure 13, multi-viewpoint three-dimensional of the present invention shows LED electronic large screen, comprise controller and display screen, controller is connected with display screen, display screen comprises PCB circuit board 7, LED luminescence chip 5, dividing plate 6 and special lens 1, LED luminescence chip 5 is located on PCB circuit board 7, and special lens 1 is located on LED luminescence chip 5, between two adjacent LED luminescence chips 5, is provided with dividing plate 6.
LED lamp pearl 5 SMD LED lamps (patch-type LED lamp), can be single lamp LED, only include a kind of luminescence chip in RGB three primary colours, are located at side by side on PCB circuit board by multiple single lamp LED.Also can be the luminescence chip of the multiple different base colors of encapsulation in lamp pearl, be located at side by side on PCB circuit board by multiple LED lamp pearls.While playing the program of multiple viewpoint numbers, need corresponding multiple independently luminescence chips.During as 4 viewpoint, be packaged with 4 independently luminescence chips, its luminescence chip has tri-kinds of RGBR, GBRG or BRGB by order from left to right, when 5 viewpoint, be packaged with 5 independently luminescence chips, its luminescence chip has tri-kinds of RGBRG, BRGBR or GBRGB by order from left to right.
Special lens is manufactured the special lens of different size according to the difference of different viewpoint numbers and LED lamp pearl size, in the time making giant-screen, special lens is applied or sticked on LED lamp pearl, also can use with protruding special lens and fasten or be attached on dividing plate, as shown in figure 14.During as 4 viewpoint, the LED lamp pearl under special lens contains 4 independently luminescence chips, has tri-kinds of RGBR, GBRG or BRGB by its luminescence chip by order from left to right.
When thereby the LED pixel that need very large in LED screen sizes is also very large, can on PCB circuit board, weld according to above being described in the SMD LED lamp (patch-type LED lamp) of large-size, be that single led lamp bead seal fills multiple luminescence chips, correspondingly special lens is done greatly, also can adopt several LED lamp pearls to install side by side, but no matter which kind of mounting means, all must be single homochromy as prerequisite to be required to be in vertical direction, the prerequisite of the sub-pixel structure strict conformance that also will must encode with program in accordance with other sub-pixel demonstration arrangement architecture.The application that must be noted that LED lamp pearl when concrete enforcement must make the color of its luminous point, vertical or oblique and program sub-pixel colors, vertical or oblique strict conformance.
Figure 15 shows that 4 viewpoint special lens installation examples.Lamp pearl on the PCB circuit board in vertical direction primary colours of every row luminescence chip is identical, and first classifies R as, and second classifies G as, and the 3rd classifies B as, and the primary colours of each row luminescence chip are all identical.No matter adopt which kind of arrangement mode, no matter also viewpoint number is how many, the lamp pearl on the PCB circuit board in vertical direction primary colours of every row luminescence chip is identical, as shown in Figure 16-Figure 22.
Figure 16 shows that 5 viewpoint special lens installation examples, luminescence chip upper left arranged askew.Figure 17 shows that 8 viewpoint special lens installation examples, luminescence chip upper left arranged askew.Figure 18 is 8 viewpoint special lens installation examples, luminescence chip upper right arranged askew.Figure 19,20 is respectively 8 viewpoints and the 6 viewpoint special lens installation examples of two row circulations, and luminescence chip is two row cycle arrangement.
As shown in figure 21, the special lens of 7 viewpoints has two kinds, and one contains three viewpoints, and another kind is contained four viewpoints.The special lens of 9 viewpoints has two kinds, and one contains four viewpoints, and another kind is contained five viewpoints, and installation example as shown in figure 22.For other viewpoint numbers, because principle is simple, differ one for example.
All special lens can use the resin or other chemical substances that meet electrical safety standard-required to make as engineering plastics etc. above, in order not produce cross-color, be made generally in transparence, and raw material should keep transparence for a long time.On the PCB circuit board that has welded SMD LED, for reliable bonding special lens, can use latticed engineering plastic flitch to do substrate.
Above embodiment is only for illustrating the preferred embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; in the ken possessing at described field those of ordinary skill; any amendment of doing within the spirit and principles in the present invention, be equal to and substitute and improvement etc., within it all should be encompassed in the technical scheme scope of request protection of the present invention.
