Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and particularly to a virtual pixel LED display screen module. Background Art

[0002] Virtual pixel LEDs utilize virtual pixel points formed based on R, G, and B, and then the pixel points are arrayed to form a virtual LED display screen.

[0003] After retrieval, a patent with the Chinese patent publication number CN101510394B discloses a method and device for virtual display of pixels on an LED display screen. The device includes a digital video source unit (1) for forming a digital video frame, an external memory (2) for storing data frames, an FPGA chip (3) for calculating data frames and converting them into virtual data frames 3, a scanning board (4), and a display screen (5). Among them, the external memory (2) and the FPGA chip (3) are integrated and are respectively connected to the digital video source unit (1) and the scanning board (4), and the scanning board (4) is connected to the display screen (5).

[0004] The above patent has the following deficiencies: Its three light-emitting units of R, G, and B are arranged in an isosceles right triangle to form a single virtual pixel point. However, after matrix array arrangement, there will be a blank area for each pixel point, and there is no light-emitting unit in this blank area, which results in a waste of space in the rectangular plane of the entire display screen, a relatively low density of light-emitting units per unit plane, and a relatively low pixel resolution.

[0005] Therefore, the present invention proposes a virtual pixel LED display screen module. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a virtual pixel LED display screen module.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A virtual pixel LED display screen module includes a frame. Inside the frame, multiple groups of virtual pixel modules are arranged in a rectangular array, and a light-transmitting plate is fixedly embedded on the front side of the frame;

[0009] The virtual pixel module includes a PCB circuit board and multiple virtual pixel units arranged in a rectangular array on the outer wall of the PCB circuit board. The virtual pixel unit is composed of two groups of virtual pixel points arranged in a centrosymmetric manner;

[0010] The virtual pixel point includes three light-emitting diodes arranged in an isosceles right triangle and fixed to the PCB circuit board, and a light-shielding cover fixed to the outer wall of the PCB circuit board in an "L" shape. One light-shielding cover wraps around the outside of the three light-emitting diodes in the same group, and the laterally or longitudinally adjacent light-shielding covers are spliced together to form a rectangular structure;

[0011] The light-shielding cover is fixed with a reflector at two of the light-emitting diodes located at the ends, and a light-transmitting sphere is fixed at the other light-emitting diode in the middle.

[0012] Preferably: An inner wall mirror-like light-gathering ring is fixed to the outer wall of the PCB circuit board at each light-emitting diode. A lens is fixed to the inner wall of the light-gathering ring, and the intersection point of the lens coincides with the light-emitting diode.

[0013] Further: The three light-emitting diodes in the same group of virtual pixel points are a red light-emitting diode, a green light-emitting diode, and a blue light-emitting diode respectively.

[0014] On the basis of the foregoing solution: A plurality of backplates are provided on the back of the frame. The number and positions of the backplates correspond to the virtual pixel modules, and half-grooves are opened on the inner wall of the frame and on the four side inner walls of the backplates. The same connecting frame is used in the inner walls of two cooperating half-grooves, and both ends of the connecting frame are respectively fixed to the two half-grooves by bolts.

[0015] A better solution in the foregoing solution is: The connecting frame is in a shape that is small in the middle and large at both ends.

[0016] As a further solution of the present invention: A plurality of groups of corresponding air vents are opened on both sides of the frame. A heat dissipation fan is installed on the inner wall of the air vent for exhausting air, and a waterproof air intake component is installed on the outer wall of the air vent for intake air.

[0017] At the same time, the waterproof air intake component includes an air inlet pipe and a water collection and drainage shell fixed to the bottom of the air inlet pipe. A fixing plate and a sliding plate axially slidably connected are respectively fixed to the bottom inner wall of the water collection and drainage shell, and the bottom of the sliding plate is connected to the bottom inner wall of the water collection and drainage shell by a first spring;

[0018] A first through hole is opened on the inner wall of the fixing plate, and a second through hole is opened on the inner wall of the sliding plate. The second through hole and the first through hole are staggered with each other.

[0019] As a preferred one of the present invention: A limiting component for limiting the sliding plate is provided on the side wall of the water collection and drainage shell. The limiting component includes an arc head limiting block and a second spring. The arc head limiting block is radially slidably connected to the inner wall of the water collection and drainage shell. One end of the second spring is buckled to the side wall of the arc head limiting block, and the other end of the second spring is buckled to the inner wall of the water collection and drainage shell, and the arc-shaped end of the arc head limiting block is in contact and cooperation with the sliding plate;

[0020] The intake pipe has a "U" - shaped structure, and the intake side of the intake pipe is vertically downward after turning.

[0021] Meanwhile, a universal - adjustable support assembly is provided at the bottom of the frame;

[0022] The universal - adjustable support assembly includes an adjustment seat fixed to the bottom of the frame and a mounting seat fixed to the bearing part.

[0023] As a more optimal solution of the present invention: One side of the adjustment seat is rotatably connected with three connecting arms one arranged in a circular array. The other end of the connecting arm one is rotatably connected with a connecting arm two. One side of the mounting seat is rotatably connected with a core shaft. The outer wall of the core shaft is sequentially rotatably connected with a hollow shaft two and a hollow shaft one. The three connecting arms two are respectively fixed to the outer walls of the core shaft, the hollow shaft two, and the hollow shaft one;

[0024] Three motors are fixed to the outer wall of the mounting seat by bolts. The output shafts of the three motors are respectively in transmission cooperation with the outer walls of the core shaft, the hollow shaft two, and the hollow shaft one through a set of gear sets.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, based on the arrangement of R, G, and B light sources in an isosceles triangle, there is an overlapping part between adjacent virtual pixel points, thus filling the gaps, making the pixel points per unit area of the display screen denser and the resolution higher.

[0027] 2. In the present invention, by setting components such as a condenser ring, a lens, a reflector, and a light - transmitting sphere, on the one hand, it can prevent the light of a single light - emitting diode from spilling and not participating in the display, increasing the display efficiency. At the same time, after the light is concentrated by the light - transmitting sphere, the display effect of a single virtual pixel point is better. Meanwhile, by using a light - shielding cover for separation, the light between adjacent virtual pixel points can be made not to affect each other, thus facilitating the color adjustment of a single virtual pixel point and increasing the color rendering accuracy of the display screen.

[0028] 3. In the present invention, the back of the entire display screen is in a splicing form, so that the volume of the constituent units of the entire "backplane" is smaller, which is convenient for production, installation, and transportation. At the same time, the installation form of a half - groove and a connecting frame is adopted between the backplane and the backplane, and between the backplane and the frame. Thus, when maintaining a single virtual pixel module, only the connecting frames around the corresponding backplane need to be disassembled, increasing the maintenance convenience.

[0029] 4. In the present invention, on the basis of ensuring heat dissipation, the intake pipe is specifically designed first to prevent rainwater from entering the interior of the frame along with the air, ensuring the safety of the device. Additionally, by providing components such as a fixing plate, a limiting component, and a sliding plate, it can also quantitatively drain the rainwater adhering to the intake pipe, so that the rainwater accumulated in the concave part in the middle of the intake pipe can be reliably discharged. At the same time, the quantitative drainage enables the rainwater to be discharged based on the accumulation amount. Thus, in most intake cases, air is inhaled from the end of the intake pipe, increasing the air path, increasing the adhesion rate of rainwater to the intake pipe, and enhancing the rainproof effect.

[0030] 5. In the present invention, by providing a universal adjustable support component, on the one hand, when multiple motors rotate synchronously, the lifting adjustment of the frame can be achieved; on the other hand, when multiple motors rotate non-synchronously, the plane angle adjustment of the frame can be realized. At the same time, all three driving parts of the entire universal adjustable support component are in a fixed state, which can effectively prevent the rotation and entanglement of the wired harnesses for power connection, etc., increasing safety.

[0042] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0043] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0044] Embodiment 1:

[0045] A virtual pixel LED display module, as Figures 1-10 shown, includes a frame 1. A plurality of groups of virtual pixel modules 2 arranged in a rectangular array are provided inside the frame 1, and a translucent plate 3 is fixedly embedded on the front side of the frame 1.

[0046] The virtual pixel module 2 includes a PCB circuit board 4 and a plurality of virtual pixel units 6 arranged in a rectangular array on the outer wall of the PCB circuit board 4. The virtual pixel unit 6 is composed of two groups of virtual pixel points 5 arranged in a centrosymmetric manner.

[0047] The virtual pixel point 5 includes three light-emitting diodes 7 arranged in an isosceles right triangle and fixed to the PCB circuit board 4, and a light-shielding cover 11 fixed to the outer wall of the PCB circuit board 4 in an "L" shape. One light-shielding cover 11 wraps around the outside of the three light-emitting diodes 7 in the same group, and the horizontally or vertically adjacent light-shielding covers 11 are spliced together to form a rectangular structure.

[0048] The light-shielding cover 11 is fixed with a reflector 10 at two of the light-emitting diodes 7 located at the ends, and the light-shielding cover 11 is fixed with a light-transmitting sphere 12 at the other light-emitting diode 7 in the middle.

[0049] On the outer wall of the PCB circuit board 4 at each light-emitting diode 7, a light-gathering ring 8 with a mirror-like inner wall is fixed. A lens 9 is fixed to the inner wall of the light-gathering ring 8, and the intersection point of the lens 9 coincides with the light-emitting diode 7.

[0050] The three light-emitting diodes 7 in the same group of virtual pixel points 5 are a red light diode, a green light diode, and a blue light diode respectively.

[0051] When the device is in use, the principle of each virtual pixel point 5 is as follows: The three light-emitting diodes 7 emit red light, green light, and blue light respectively. After the light emitted by each light-emitting diode 7 is reflected by the light-gathering ring 8 and refracted by the lens 9, most of the light will be emitted in the form of parallel light. Among them, two groups of parallel light are reflected by the reflector 10 and then irradiated on the light-transmitting sphere 12, and the other one is directly irradiated on the light-transmitting sphere 12. The three groups of light are "mixed" by the light-transmitting sphere 12 to display colors, forming a virtual pixel point 5. Two virtual pixel points 5 form a virtual pixel unit 6, and then the entire display screen pixels are formed through the rectangular array of virtual pixel units 6 and the rectangular array of virtual pixel modules 2.

[0052] Correspondingly, the device also needs to include electrical components such as a power supply for powering the PCB circuit board 4 and the light-emitting diodes 7, a controller for control, and a driver. Since it is prior art and no creative work has been done in this embodiment, it will not be elaborated here.

[0053] The light-gathering principle of the light-transmitting sphere 12 is as follows: The surface area of the light-transmitting sphere 12 is relatively large, and its curvature makes the light distribute more widely inside the sphere. Some light is finally emitted in different directions after multiple reflections, which causes the light-transmitting sphere 12 to act as a "light diffuser", dispersing the light energy originally propagating in the parallel direction to a wider angular range, making it brighter as a whole.

[0054] In this device, based on the arrangement of R, G, and B light sources in an isosceles triangle, there is an overlapping part between adjacent virtual pixel points 5, thus filling the gaps, making the pixel points of the display screen per unit area denser and the resolution higher.

[0055] In addition, by providing components such as the condenser ring 8, the lens 9, the reflector 10, and the light-transmitting sphere 12, on the one hand, the device can prevent the light of a single light-emitting diode 7 from spreading and not participating in the display, increasing the display efficiency. At the same time, after the light is concentrated by the light-transmitting sphere 12, the display effect of a single virtual pixel 5 is better. At the same time, by using the light-shielding cover 11 for separation, the light between adjacent virtual pixels 5 can be made not to affect each other, thus facilitating the color adjustment of a single virtual pixel 5 and increasing the color rendering accuracy of the display screen.

[0056] To solve the problems of installation and maintenance convenience; as Figure 5 shown, a plurality of backplates 13 are provided on the back of the frame 1. The number and positions of the backplates 13 correspond to the virtual pixel modules 2. Semi-grooves 14 are provided on the inner wall of the frame 1 and the four-side inner walls of the backplates 13. The same connecting frame 15 is used in the inner walls of two cooperating semi-grooves 14, and both ends of the connecting frame 15 are respectively fixed to the two semi-grooves 14 by bolts.

[0057] The connecting frame 15 is in a shape that is small in the middle and large at both ends.

[0058] For this device, the back of the entire display screen is in a splicing form, so that the volume of the component unit of the entire "backplate" is smaller, facilitating production, installation, and transportation. At the same time, the installation form of the semi-grooves 14 and the connecting frame 15 is adopted between the backplates 13 and between the backplates 13 and the frame 1. Therefore, when maintaining a single virtual pixel module 2, only the connecting frames 15 around the corresponding backplate 13 need to be disassembled, increasing the maintenance convenience.

[0059] To solve the problems of heat dissipation and waterproofing; as Figure 6 shown, a plurality of groups of corresponding ventilation openings 16 are provided on both sides of the frame 1. A heat dissipation fan is installed on the inner wall of the ventilation opening 16 for exhausting air, and a waterproof air intake assembly 18 is installed on the outer wall of the ventilation opening 16 for intake air.

[0060] The waterproof air intake assembly 18 includes an air inlet pipe 19 and a water collection and drainage shell 20 fixed to the bottom of the air inlet pipe 19. A fixing plate 21 and a sliding plate 23 axially slidably connected are respectively fixed to the bottom inner wall of the water collection and drainage shell 20. The bottom of the sliding plate 23 is connected to the bottom inner wall of the water collection and drainage shell 20 by a first spring 24.

[0061] A first through hole 25 is provided in the inner wall of the fixing plate 21, and a second through hole 26 is provided in the inner wall of the sliding plate 23. The second through hole 26 and the first through hole 25 are staggered with each other.

[0062] A limiting component 22 for limiting the slide plate 23 is provided on the side wall of the water collecting and draining shell 20. The limiting component 22 includes an arc head limiting block 27 and a second spring 28. The arc head limiting block 27 is radially slidably connected to the inner wall of the water collecting and draining shell 20. One end of the second spring 28 is buckled on the side wall of the arc head limiting block 27, and the other end of the second spring 28 is buckled on the inner wall of the water collecting and draining shell 20. The arc-shaped end of the arc head limiting block 27 is in contact and cooperation with the slide plate 23.

[0063] The air inlet pipe 19 has a "U" - shaped structure, and the air inlet side of the air inlet pipe 19 is vertically downward after turning.

[0064] When the display screen is in use, the heat dissipation fan starts to exhaust air outward at the same time. Due to the reduction of the internal air pressure, external air will enter the inside of the frame 1 from the air inlet pipe 19 to complete heat dissipation and ensure the normal operation of the device.

[0065] And in rainy days, since there will be rainwater in the air, the rainwater entering the inside of the frame 1 will cause a short - circuit fault. In this device, when the rainwater enters along the air inlet pipe 19, at the rainwater inlet, part of the rainwater will directly drop due to its own weight being greater than the fluid force of the air on it. Another part of the rainwater will have three direction changes after entering the air inlet pipe 19. During the process of direction change, the rainwater will contact the inside of the air inlet pipe 19 and adhere to the inner wall of the air inlet pipe 19 due to tension and viscosity, and then gradually flow downward under the action of gravity into the water collecting and draining shell 20. When the amount of rainwater is small, the pressure of the rainwater on the slide plate 23 is less than the resistance of the limiting component 22 to the slide plate 23, and the bottom of the water collecting and draining shell 20 is closed, and the rainwater gradually accumulates until the pressure of the rainwater on the slide plate 23 is greater than the resistance of the limiting component 22 to the slide plate 23, then the slide plate 23 will move downward, so that the water collecting and draining shell 20 is communicated with the outside through the first through - hole 25, the gap between the fixing plate 21 and the slide plate 23, and the second through - hole 26, and the rainwater is discharged downward. After the discharge, the slide plate 23 will be reset by the elastic force of the first spring 24.

[0066] In this device, on the basis of ensuring heat dissipation, firstly, the air inlet pipe 19 is designed specifically to prevent rainwater from entering the inside of the frame 1 along with the air, ensuring the safety of the equipment. In addition, by setting components such as the fixing plate 21, the limiting component 22, and the slide plate 23, it can also drain the rainwater adhering to the inside of the air inlet pipe 19 quantitatively, so that the rainwater accumulated in the concave part in the middle of the air inlet pipe 19 can be reliably discharged. At the same time, the quantitative drainage can make the rainwater be discharged based on the accumulation amount. Thus, in most cases of air intake, air is inhaled from the end of the air inlet pipe 19, increasing the air path, increasing the adhesion rate of rainwater to the air inlet pipe 19, and increasing the rain - proof effect.

[0067] In the use of this embodiment, the principle of each virtual pixel point 5 is as follows: three light-emitting diodes 7 emit red light, green light, and blue light respectively. After the light emitted by each light-emitting diode 7 is reflected by the condensing ring 8 and refracted by the lens 9, most of the light will be emitted in the form of parallel light. Two groups of parallel light are reflected by the reflector 10 and then irradiated on the light-transmitting sphere 12, and the other group is directly irradiated on the light-transmitting sphere 12. The three groups of light are "mixed" by the light-transmitting sphere 12 to show colors, forming a virtual pixel point 5. Two virtual pixel points 5 form a virtual pixel unit 6, and then the entire display screen pixels are formed by the virtual pixel units 6 in a rectangular array and the virtual pixel modules 2 in a rectangular array. In addition, when the display screen is in use, the cooling fan starts to exhaust air outwards at the same time. Due to the reduction of the internal air pressure, external air will enter the frame 1 from the air inlet pipe 19 to complete heat dissipation and ensure the normal operation of the device. And in rainy days, since there will be rainwater in the air, the rainwater entering the interior of the frame 1 will cause a short-circuit fault. In this device, when the rainwater enters along the air inlet pipe 19, at the inlet of the rainwater, some rainwater will directly fall due to its own weight being greater than the fluid force of the air on it. Another part of the rainwater will have three direction changes after entering the air inlet pipe 19. During the process of changing the line, the rainwater will contact the inside of the air inlet pipe 19 and will adhere to the inner wall of the air inlet pipe 19 due to the tension and viscosity, and then gradually flow downward under the action of gravity into the water collection and drainage shell 20. When the amount of rainwater is small, the pressure of the rainwater on the slide plate 23 is less than the resistance of the limit component 22 to the slide plate 23, and the bottom of the water collection and drainage shell 20 is closed, and the rainwater gradually accumulates until the pressure of the rainwater on the slide plate 23 is greater than the resistance of the limit component 22 to the slide plate 23, the slide plate 23 will move downward, so that the water collection and drainage shell 20 communicates with the outside through the through hole one 25, the gap between the fixing plate 21 and the slide plate 23, and the through hole two 26, and the rainwater is discharged downward. After the discharge, the slide plate 23 will be reset by the elastic force of the spring one 24.

[0068] Embodiment 2:

[0070] The universal adjustable support assembly 17 includes an adjustment seat 29 fixed to the bottom of the frame 1 and a mounting seat 34 fixed to the bearing part. In this embodiment, the specific definition of the bearing part is not limited, and it can be a desktop, a bracket or a wall surface, etc., which is related to the installation position of the display screen, and the bearing part is determined accordingly according to the actual installation position.

[0071] One side of the adjustment seat 29 is rotatably connected with three connecting arms one 30 arranged in a circular array. The other end of the connecting arm one 30 is rotatably connected with a connecting arm two 31. One side of the mounting seat 34 is rotatably connected with a core shaft 37. The outer wall of the core shaft 37 is sequentially rotatably connected with a hollow shaft two 36 and a hollow shaft one 35. The three connecting arms two 31 are respectively fixed to the outer walls of the core shaft 37, the hollow shaft two 36, and the hollow shaft one 35.

[0072] Three motors 33 are fixed to the outer wall of the mounting seat 34 by bolts. The output shafts of the three motors 33 are respectively in transmission cooperation with the outer walls of the core shaft 37, the hollow shaft two 36, and the hollow shaft one 35 through a set of gear sets 32.

[0073] In the present invention, by setting the universal adjustment type support assembly 17, on the one hand, when multiple motors 33 rotate synchronously, the lifting adjustment of the frame 1 can be realized. On the other hand, when multiple motors 33 rotate non-synchronously, the plane angle adjustment of the frame 1 can be realized. At the same time, all three driving parts of the entire universal adjustment type support assembly 17 are in a fixed state, which can effectively prevent the wiring harness for power connection from rotating and winding, etc., and increase safety.
