Description

Technical Field

[0001] The present invention belongs to the technical field of small pitch display, and in particular relates to a zero pitch continuous display device. Background Art

[0002] At present, in the field of large-screen display, the main forms are LCD (including splicing technology), LED, DLP, projection (including fusion technology), etc. LCD display technology, that is, liquid crystal in the traditional sense, has a small single screen size. When splicing, there will be obvious splicing gaps, mostly 1mm-15mm. This splicing gap is often a black physical area, which cannot display images normally, and this physical black area cannot be changed, so it is difficult to achieve zero spacing and continuous display effects. Although the gaps made by LED when splicing are very small, LED is directly used as a light source for display. The LED display screen that people usually see is composed of many RGB lamp beads. When the lamp beads are lit, only part of the lamp beads, or the surroundings are bright, that is, the space between the lamp beads, is not displayed, or the brightness of this area is less than the brightness of the position of the lamp beads. This display effect is uneven and discontinuous, and the effect of viewing is dazzling, because in order to achieve a certain uniform effect and illuminate the brightness around the lamp beads, the brightness of the lamp beads themselves must be increased. To increase the brightness, a lot of power is required. The final feeling given to viewers is that the display is too dazzling, it is difficult to watch for a long time, and the grayscale and contrast effects are poor. DLP and projection also have similar or even more serious problems.

[0003] LED, also known as light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. When splicing existing lamp beads, due to mistakes made by staff, slight errors may occur in the lamp beads after splicing, resulting in uneven arrangement of the lamp beads and poor display effect. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a zero-spacing continuous display device, which effectively solves the problems raised in the above background technology. In order to achieve zero-spacing display, the lens on the upper part of the lamp bead must be seamlessly spliced, so that zero-spacing splicing can be achieved physically. At this time, the zero spacing only realizes the seamless splicing of the plane. In the vertical direction, it is also necessary to achieve high consistency. Otherwise, when viewed from the side, the lens on the lamp bead will appear to be highly inconsistent, that is, uneven in the traditional sense. In order to solve this problem, the first thing is to solve the flatness of the lens itself, so the lens structure design, force analysis, and processing process are extremely important. Generally, it is guaranteed by high-precision injection molding equipment with good machine profiles; second, small-pitch LED lamp beads are packaged in an array on a PCB panel with controllable flatness. If you want to achieve the splicing flatness of the lens, the flatness of the PCB must be controlled very finely.

[0005] Through the above two points, it is ensured that this invention physically achieves seamless splicing in three directions and fine control of flatness, thereby ensuring zero-spacing splicing.

[0006] In order to solve the continuous display effect of this technology, the early stage is the realization of the above-mentioned zero spacing, which is also the basis of continuous display. Many large-screen display technologies only spend a lot of effort on the back end to adjust the effect, but often ignore the early work. This invention avoids the pain points and conventional operations of small-pitch LEDs, and presents the picture evenly through the point light source through a polymer lens. Because the small-pitch lamp beads and the lamp beads do not emit light, such physical areas are difficult to solve, and it is fundamentally impossible to achieve continuous display. It can only be a flickering effect. In order to solve this problem, the brightness of the lamp beads is often increased, which not only loses grayscale and contrast, but also causes the lamp beads to heat up due to high power, causing other problems such as dead lights and blind lights. In addition, while increasing the power, the heat is also brought up, which also brings troubles to the overall large-screen heat dissipation, making it impossible for viewers to get close to the screen, and the experience effect is also greatly reduced. Due to the increase in the power of the lamp beads, there is no need to talk about the concepts of saving points, energy saving, and environmental protection.

[0007] This invention uses a clever design to make the imaging lens structure more reasonable by using the principle of point light emission of small-pitch LED lamp beads. The point light source of the lamp beads forms a surface light source to the lens, so that the displayed image is transferred to the lens surface. This makes the image effect softer, the color more realistic, and the continuous display more uniform.

[0046] The present invention adopts a light board PCB board 1, and packages small-pitch LED lamp beads 2 on the light board PCB board 1. The LED lamp beads are arranged on the light board PCB board 1 in a certain array manner, such as Figure 2 As shown, conventional small-pitch LED display technology displays by lighting up LED lamp beads, that is, the position of the light is as follows Figure 2 On surface A, the light path of the light is scattered in all directions, but the area between the small-pitch LED lamp beads 2, such as the black box area in the figure, is a non-display area. Even in actual application, the brightness of the light is increased by increasing the power of the lamp beads, but the brightness of the black physical area between the lamp beads 2 still cannot reach the brightness of surface A;

[0047] In order to achieve point lighting and continuous display of small-pitch LED lamp beads 2, it is necessary to conduct and transfer the light source of surface A through lens 3. Figure 1 The lens 3 in the middle is fixed on the lamp board PCB1 by a specific bonding method. At this time, fine assembly accuracy is required. The vertical distance C between the lower surface of the lens 3 and the lamp bead surface A is generally 1-3mm, and the left and right dimensions D are generally within 0.1mm, ensuring that the lens 3 can cooperate well with the small-pitch lamp beads 2 to prevent position deviation and cause differences in display effects.

[0048] When the lens 3 and the lamp bead 2 are well matched, the lamp bead 2 will emit light, and the light path will follow the following Figure 3 As shown in the schematic diagram, the light is evenly scattered and all transmitted to the surface B of the lens 3, thus completing the continuous display between the lenses 3.

[0049] Since the joint gap between the lenses 3 is almost close to zero, if the light is transmitted through the lens 3, all lens surfaces form a consistent image, so that the black area between the original lamp beads 2 is transmitted on the surface of the lens 3. In summary, this invention displays the original point light source of the LED lamp beads with small spacing perfectly on the lens 3 through a certain conduction, so that the display screen has no physical gaps and achieves a truly continuous display. And the size error of the wedge 2 itself. The shape of the wedge 2 forms the left and right matching angles of the die-cast aluminum 1 and the horizontal structural thickness of the wedge.

[0050] Working principle: When the LED lamp beads are working, firstly, the connection mechanism 4 is connected to the shell 7 through the limit groove 8, and by aligning the fixing block 42 with the limit groove 8, the small-pitch LED lamp beads 2 will pass through the inner side of the hole groove 21 and enter the inner side of the shell 7, and then the connecting plate 41 is rotated. At this time, the limit block 43 is adapted to the size of the limit groove 8, so that the connecting plate 41 rotates along the outer side of the shell 7, so that when the small-pitch LED lamp beads 2 fail, only the connection mechanism 4 needs to be replaced, avoiding the replacement of the entire shell 7, reducing the use cost of the LED lamp beads and saving resources;

[0051] Then, the position of the lens 3 and the small-pitch LED lamp bead 2 is adjusted by the rotating mechanism 20, and the rotating block 201 in the rotating mechanism 20 is screwed to drive the rotating rod 19 to rotate. At this time, the rotating rod 19 will drive the rotation of the gear 18. Since the gear 18 is meshed with the gear rod 16, the rotation of the gear 18 will drive the gear rod 16 to move upward. At this moment, the gear rod 16 drives the piston 2 17 to slide along the inner wall of the U-shaped groove 15. Based on the principle of the U-shaped groove 15, the piston 14 will move downward along the inner wall of the U-shaped groove 15, and the downward movement of the piston 14 will drive the connecting rod 1 3 moves downward, thereby driving the slide plate 5 to move downward. Since the slide plate 5 is fixedly connected to the lens 3, the lens 3 is driven downward, and the shading plate 6 at the bottom of the slide plate 5 also moves downward accordingly. When the rotating block 201 stops rotating, the clamping block 203 inside the protective block 202 at this moment has an extrusion force on the rotating block 201, thereby preventing the rotating block 201 from moving, thereby realizing the adjustment of the position of the lens 3 from the small-pitch LED lamp beads 2, improving the accuracy of the small-pitch LED lamp beads 2 when in use, improving the picture presentation effect, and optimizing the viewer's experience.

[0052] Then, the adjacent shells 7 are connected together, and the block 12 is driven by the card block 11 to enter the inner side of the adjacent shell 7, so that the card block 11 slides along the inner wall of the card slot 9, and then the block 12 is engaged with the card slot 9, and the rotating mechanism 20 enters the inner side of the accommodating groove 10, so that no gap is generated between the adjacent shells 7, and then the arranged shells 7 are installed on the top of the light board PCB board 1, avoiding the uneven layering of the shells 7 during the installation process and improving the display effect.
