Description

Technical Field

[0001] The present invention relates to the technical field of naked-eye 3D devices, and particularly to an LED naked-eye 3D display screen and an installation method thereof. Background Technique

[0002] The effect of a naked-eye 3D display screen is usually composed of two angled pictures. At the splicing part of the screen, replacing the angled corner with an arc corner can greatly improve the naked-eye 3D effect. A naked-eye 3D display screen does not require special glasses and can be directly viewed with the naked eye. Through special technologies and algorithms, the parallax effect of the human eye is simulated, enabling viewers to directly feel the three-dimensional effect with the naked eye.

[0003] The working principle of a naked-eye 3D display screen usually involves two main aspects: parallax and viewing angle. Parallax refers to the human eye's perception of depth and three-dimensional effect through the differences between the left and right eyes, while the viewing angle refers to the images seen by the viewer at different positions and angles. The naked-eye 3D display screen displays different images on the screen, making the images seen by the left and right eyes slightly different, thus generating a three-dimensional effect.

[0004] Outdoor large-scale naked-eye 3D display screens are generally assembled by multiple display units. To attract people, such large display screens are installed at the corners of shopping malls or intersections. Most of the assembly methods are to build a steel structure support frame and fix it with screws. The corner positions are close to the ventilation openings and are greatly affected by urban winds. The display screen has a large area and a large windward area. When the wind blows dirt towards the display screen, if it encounters a humid environment, the dirt will stick to the screen surface, affecting the display effect. It is not easy to clean the large screen. Workers need to hang in front of the screen for cleaning. At the same time, because the display screen is in the off state during cleaning, the black screen makes it difficult to identify the surface dirt. If the whole screen is not cleaned for a long time, the cleaning will be incomplete. However, due to the influence of strong winds in the windy season, it is difficult for the display screen to maintain a clean state for a long time. But if the whole screen needs to be cleaned every time dirt is found, it is time-consuming, laborious, and increases the cost. Summary of the Invention

[0005] The purpose of the present invention is to provide an LED naked-eye 3D display screen and an installation method thereof to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: an LED naked-eye 3D display screen and its installation method, including a display screen group, a limit frame, a fixing frame, and a dirt detection component. Among them, there are two sets of upper and lower limit frames, the display screen group is arranged between the two sets of limit frames, the fixing frame is arranged at a certain distance at the rear end of the display screen group and is the support unit of the display screen group, the dirt detection component is installed on the upper limit frame of the display screen group, and the dirt detection component includes a driving rotating rod, a driving motor, a driving gear set, a driven rotating rod, a driven gear set, several swing arms, a scanner, a signal transmitter, and a fixing block. Among them, the driving rotating rod and the driven rotating rod are arranged in parallel through the fixing block and are rotationally matched with the fixing block. The driving end of the driving motor is connected to one end of the driving rotating rod. The driving gear set is sleeved on the driving rotating rod. The driven gear set is sleeved on the driven rotating rod and is in tooth engagement with the driving gear set. The swing arms are grouped in twos and are respectively sleeved on the driving rotating rod and the driven rotating rod. One of the swing arms in the same group is installed with a scanner, and the other is installed with a signal transmitter.

[0007] Further, the swing arm is a curved arm structure, and the installation directions of the scanner and the signal transmitter form a certain angle with the vertical plane.

[0008] Further, the scanner is used to scan the dirt attachment situation on the display surface of the display screen group. By magnifying the scanned image, capturing the dirt blocks, and outlining them, the dirt attachment area can be obtained. The signal transmitter uses an infrared transmitter.

[0009] The display screen group is composed of multiple flat screens and bent screens spliced together. Signal induction surfaces are provided on the backs of the flat screens and the bent screens for receiving the infrared signals emitted from the signal transmitter.

[0010] Further, the fixing frame is built into a grid structure, and each grid corresponds to the back of each flat screen. Fixing plates are installed above and below the grid, and a climbing rod is provided in the lower grid for easy climbing.

[0011] Further, a fixing rod is threadedly connected to the back of the flat screen. The other end of the fixing rod passes through the fixing plate and is fixed with a nut, and a handle rod is also provided for easy gripping.

[0012] Further, a telescopic rod is provided at the connection end of the fixing rod and the flat screen. A bottom plate is fixed at the bottom of the telescopic rod. A shock-absorbing spring is sleeved outside the telescopic rod, and a pressure sensing module is provided on the pressing surface of the bottom plate.

[0013] Further, the telescopic length of the telescopic rod should not exceed 2 cm, which is mainly used in strong wind weather to play a buffering effect. It can relieve the pressure of the vibration of multiple flat screens on the fixing frame and can judge whether a dangerous situation will occur by detecting the pressure magnitude, and the power supply can be turned off in advance to avoid potential hazards.

[0014] Furthermore, the fixing frame can be additionally extended to lead out an extension frame for support and fixation.

[0015] Furthermore, the specific installation method is as follows:

[0016] Step 1: Build the limit frame and the fixing frame, fix the two limit frames in appropriate positions, build the fixing frame at the rear side of the limit frame, and reserve a distance for people to pass through.

[0017] Step 2: Fix one end of the fixing rod at the rear side of the display screen group, pass the other end through the fixing plate, fit the display surface of the display screen group against the back of the limit frame, and then fix it with a nut and install the handlebar. During this process, the fixing rod can slide within the hole positions of the fixing plate.

[0018] Step 3: Lay the driving rotating rod and the driven rotating rod side by side on the upper limit frame, sleeved with the driving gear set and the driven gear set at intervals, assemble each group of swing arms, install the scanner and the signal transmitter, and finally install the driving motor.

[0019] Furthermore, the specific usage method is as follows:

[0020] After installation, command the driving motor to drive the scanner to scan the surface of the display screen group from bottom to top every hour, calculate the dirt adhesion area of each screen, compare it with the set value. If it is judged that the dirt adhesion on the surface of a certain screen seriously affects the visual sense, swing the signal transmitter to locate this screen and emit an infrared signal to the signal sensing surface. The scanner, the signal sensing surface of each screen, and the pressure sensing module on the bottom plate pressing surface are all signal-connected to the central processor.

[0021] The central manager collects the scanning results (qualified / unqualified) of each scanner, records the specific positions of the unqualified screens, cuts off the power supply of this display screen and notifies the personnel to clean it. When the staff cleans the lower display screens, they can loosen the nuts at the corresponding positions, directly pull the handlebar to pull out the display screen to be cleaned, and then drill between the display screen group and the fixing frame to the front of the corresponding display screen for cleaning operations. When cleaning the upper display screens, they can climb up with the help of the climbing poles set on the lower grid.

[0022] The central manager collects the pressure signals detected by each pressure sensing module, compares them with the set warning pressure value, and judges whether there is a risk of structural dislocation in the pressure brought by the wind force to the surface of the display screen group in strong wind weather. If so, immediately cut off the power supply of the display screen group and notify the need to evacuate the crowd below to avoid potential casualties caused by the collapse and falling of the display screen group.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: By providing a dirt detection component, the surface of each display screen can be scanned for dirt, the dirt adhesion area can be calculated, and the display screens in need of cleaning can be located; By providing a fixed rod, the pressure sensing module therein can be used to detect whether the force exerted by the wind on the display screen exceeds the warning value in strong wind weather, so as to give an early warning and reduce the occurrence of accidents and casualties.

[0032] The following further describes the technical solutions of the present invention in detail with reference to the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-6, the present invention provides a technical solution: an LED naked-eye 3D display screen and its installation method, including a display screen group 1, a limit frame 2, a fixing frame 3, and a dirt detection component 4. Among them, there are two sets of upper and lower limit frames 2, the display screen group 1 is arranged between the two sets of limit frames 2, the fixing frame 3 is arranged at a certain distance from one end of the rear side of the display screen group 1 and is a support unit for the display screen group 1, and the dirt detection component 4 is installed on the upper limit frame 2 of the display screen group 1. The dirt detection component 4 includes a driving rotating rod 41, a driving motor 42, a driving gear set 43, a driven rotating rod 44, a driven gear set 45, several swing arms 46, a scanner 47, a signal transmitter 48, and a fixing block 49. Among them, the driving rotating rod 41 and the driven rotating rod 44 are arranged in parallel through the fixing block 49 and are rotationally matched with the fixing block 49. The driving end of the driving motor 42 is connected to one end of the driving rotating rod 41. The driving gear set 43 is sleeved on the driving rotating rod 41, the driven gear set 45 is sleeved on the driven rotating rod 44 and is in tooth engagement with the driving gear set 43. The swing arms 46 are grouped in pairs and are respectively sleeved on the driving rotating rod 41 and the driven rotating rod 44. One of the swing arms 46 in the same group is installed with a scanner 47, and the other is installed with a signal transmitter 48.

[0034] It should be added that: the swing arm 46 is a curved arm structure, and the installation directions of the scanner 47 and the signal transmitter 48 form a certain angle with the vertical plane.

[0035] In actual operation, after the driving motor 42 drives the driving rotating rod 41 to rotate, the driving gear set 43 on the driving rotating rod 41 will drive the driven rotating rod 44 to rotate in the opposite direction, so that the rotation direction of the driven rotating rod 44 is opposite to that of the driving rotating rod 41, and finally the scanner 47 and the signal transmitter 48 on a set of swing arms 46 rotate mirror-symmetrically. When the scanner 47 locks a certain position on the front of the display screen group 1, the signal transmitter 48 in the same group locks the position on the back of the display screen group 1 corresponding to this position.

[0036] The scanner 47 is used to scan the dirt attachment situation on the display surface of the display screen group 1. By magnifying the scanned image, capturing the dirt block, and outlining it, the dirt attachment area can be obtained. The signal transmitter 48 uses an infrared transmitter.

[0037] The display screen group 1 is composed of multiple flat screens 11 and bent screens 12 spliced together. A signal induction surface 13 is provided on the back of the flat screen 11 and the bent screen 12 for receiving the infrared signal emitted from the signal transmitter 48.

[0038] In actual operation, after the scanner 47 senses the dirt attachment on the surface of the display screen group 1, it will make a unified record. When the dirt attachment rate of a certain flat screen 11 or bent screen 12 exceeds the set value, the scanner 47 will lock this screen, and at the same time, the corresponding signal transmitter 48 will emit an infrared signal to the back of this screen, that is, the signal induction surface 13, to determine the specific position.

[0039] The fixing frame 3 is built into a grid structure, and each grid corresponds to the back of each flat screen 11. Fixing plates 31 are installed above and below the grid, and a climbing rod 32 is provided in the lower grid for easy climbing.

[0040] A fixing rod 5 is threadedly connected to the back of the flat screen 11. The other end of the fixing rod 5 passes through the fixing plate 31 and is fixed with a nut 6, and a handle rod 7 is also provided for easy gripping.

[0041] A telescopic rod 51 is provided at the connection end of the fixing rod 5 and the flat screen 11. The bottom of the telescopic rod 51 is fixed with a bottom plate 52. A shock-absorbing spring 53 is sleeved outside the telescopic rod 51, and a pressure sensing module is provided on the pressing surface of the bottom plate 52.

[0042] It should be added that: the telescopic length of the telescopic rod 51 should not exceed 2 cm, which is mainly used in strong wind weather to play a buffering effect, can relieve the pressure of the fixing frame 3 caused by the vibration of multiple flat screens 11, and can judge whether dangerous situations will occur by detecting the pressure magnitude, and the power supply can be turned off in advance to avoid potential hazards.

[0043] For the bent screen 12, the fixing frame 3 can additionally lead out an extension frame 33 for support and fixation.

[0044] The specific installation method is as follows:

[0045] Step 1: Build the limit frame 2 and the fixing frame 3, fix the two limit frames 2 in appropriate positions, and build the fixing frame 3 behind the limit frame 2, leaving a distance for people to pass through.

[0046] Step 2: Fix one end of the fixing rod 5 at the back of the display screen group 1, pass the other end through the fixing plate 31, fit the display surface of the display screen group 1 to the back of the limit frame 2 and then fix it with the nut 6 and install the handle rod 7. During this process, the fixing rod 5 can slide within the hole positions of the fixing plate 31.

[0047] Step 3: Lay the driving rotating rod 41 and the driven rotating rod 44 side by side on the upper limit frame 2, sleeved with the driving gear set 43 and the driven gear set 45 at intervals, assemble each swing arm 46 and install the scanner 47 and the signal transmitter 48, and finally install the driving motor 42.

[0048] The specific usage method is as follows:

[0049] After installation, the driving motor 42 is commanded to drive the scanner 47 to scan the surface of the display screen group 1 from bottom to top in one-hour units, calculate the dirt adhesion area of each screen, compare it with the set value. If it is determined that the dirt adhesion on the surface of a certain screen seriously affects the visual sense, the signal transmitter 48 is swung to position at this screen and an infrared signal is emitted to the signal sensing surface 13. The scanner 47, the signal sensing surface 13 of each screen, and the pressure sensing module on the pressing surface of the bottom plate 52 are all signal-connected to the central processor.

[0050] In one embodiment, the central manager collects the scanning results (qualified / unqualified) of each scanner 47, records the specific positions of the unqualified screens, cuts off the power supply of this display screen and notifies the personnel to clean it. When the staff cleans the display screen at a low position, the nut 6 can be loosened at the corresponding position, and the handlebar 7 can be directly pulled to pull out the display screen to be cleaned, and then drill between the display screen group 1 and the fixing frame 3 to the front of the corresponding display screen for cleaning operations. When cleaning the display screen at a high position, the climbing rod 32 set on the low-position grid can be used to climb up;

[0051] In one embodiment, the central manager collects the pressure signals detected by each pressure sensing module, compares them with the set warning pressure value, and judges whether there is a risk of structural dislocation in the pressure brought by the wind force to the surface of the display screen group 1 in strong wind weather. If so, the power supply of the display screen group 1 is immediately disconnected, and the personnel below are notified to evacuate to avoid potential casualties caused by the collapse and fall of the display screen group 1.

[0052] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0053] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
