Description

Technical Field

[0001] The present application relates to the technical field of display screens, and in particular, to a light guide component, a mechanical pixel display unit, and a display system. Background Art

[0002] The existing mechanical flip dot matrix screens (also known as mechanical flip display screens) have a single imaging color and cannot achieve a color mechanical pixel effect; or rather, the display units in the existing mechanical flip display screens are used in cooperation with LED lights, but there are problems of light leakage and light decay, resulting in poor imaging effects of the mechanical flip display screens. Summary of the Invention

[0003] The present application provides a light guide component, a mechanical pixel display unit, and a display system, which can solve the problem of poor imaging effects of mechanical flip display screens in the prior art.

[0004] In a first aspect, the present invention provides a light guide component, including:

[0005] A light guide tube, on the end face of which a light emitting surface is formed; and

[0006] A light guide column, disposed on the tube wall of the light guide tube, the light guide column having a light incident position for setting a light source;

[0007] Wherein, the light generated by the light source is reflected in the light guide column, enters the tube wall of the light guide tube, and is emitted from the light emitting surface.

[0008] In the above implementation process, the light generated by the light source will enter the light guide column, and the light is reflected in the light guide column until it enters the tube wall of the light guide tube. The light propagates in the tube wall of the light guide tube and is finally emitted from the light emitting surface. The light guide column is a solid columnar light guide structure, and its principle is similar to that of an optical fiber. It has a low light loss ratio, can efficiently guide light, ensure that there is no light leakage between the light source and the light guide column, and can effectively make the light enter the light guide tube. The light guide tube can be regarded as a plate-shaped light guide structure connected end to end. The light enters the tube wall of the light guide tube through the light guide column, which can solve the problem of side light leakage of the plate-shaped light guide structure in the prior art. Consistent with the light guide principle of the optical fiber, the light guide tube can make the light be concentratedly emitted from the light emitting surface, ensuring the light emitting effect; at the same time, the light guide tube can be designed as a tubular structure of any shape to meet the design requirements. When the light guide component is applied to a mechanical flip display screen, the flap in the mechanical flip display screen can be located in the light guide tube, and the light emitted from its light emitting surface can supplement the illumination of the mechanical flip display screen, improving the imaging effect of the mechanical flip display screen and making its imaging rich and vivid.

[0009] In an optional embodiment, the light emitting surface includes a light condensing structure.

[0010] In the above implementation process, the light - concentrating structure can concentrate light, enabling the light to be emitted intensively from the light - emitting surface. The light - concentrating structure can be a matte frosted structure, a micro - prism structure, etc. provided on the end face of the light - guiding tube, or other structures capable of achieving light concentration.

[0011] In an alternative embodiment, the surface of the light - guiding tube has a mirror - polished layer.

[0012] In the above implementation process, for the surface of the light - guiding tube, that is, the inner surface and the outer surface of the tube wall of the light - guiding tube are mirror - polished to form a mirror - polished layer, which can ensure the efficient reflection of light inside the tube wall of the light - guiding tube; or after mirror - polishing, mirror electroplating / diffuse silver spraying is performed on it, which can further improve the light reflection and diffusion efficiency inside the tube wall and ensure that the light does not leak out. It should be noted that when the light - emitting surface is at the top of the light - guiding tube, a mirror - polished layer can also be formed at the bottom end of the light - guiding tube.

[0013] In an alternative embodiment, the light - guiding column is conical, the bottom surface of the light - guiding column forms a light - incident position, and the light - guiding column and the tube wall of the light - guiding tube are connected by a transition zone with a gradual change.

[0014] In the above implementation process, the light - guiding column is conical, and its vertex angle is smoothly connected to the light - guiding tube through a transition zone, which can effectively guide the light from the light - incident position to the tube wall of the light - guiding tube; at the same time, through the design of the size of the light - guiding column, the incident angle of the light is made as small as possible, so that the light reflects in a spiral - bending upward trajectory inside the light - guiding column and the tube wall, achieving the effect of total reflection.

[0015] In an alternative embodiment, a concave - lens structure is formed at the light - incident position.

[0016] In the above implementation process, the concave - lens structure can further increase the proportion of the imported light, enabling the light generated by the light source to be efficiently imported into the light - guiding column.

[0017] In a second aspect, the present invention provides a mechanical pixel display unit, including a mechanical optical part, a driving part, a light source, a PCB board, and a light - guiding component according to any one of the foregoing embodiments;

[0018] The light source, the driving part, and the light - guiding component are connected to the PCB board, and the light source corresponds to the light - incident position of the light - guiding column;

[0019] The mechanical optical part has a diffuse - reflection surface, and the diffuse - reflection surface corresponds to the light - emitting surface;

[0020] The driving part is connected to the mechanical optical part and drives the diffuse - reflection surface to deflect relative to the light - emitting surface.

[0021] In the above implementation process, the mechanical pixel display unit uses the principle of mechanical optics pixels in cooperation with a light source and a light guide component for the imaging display of color mechanical pixels. The principle of mechanical optics pixels is as follows: 1. By controlling the angle of the mechanical optical part (such as a flap), the brightness of the diffuse reflection surface is precisely controlled, so as to achieve precise control of the intermediate gray levels of the mechanical pixels from black to white; 2. By precisely controlling the angle, the visual duty cycle of the mechanical optical part (such as a flap) is controlled, so as to achieve the display effect of the size of the mechanical pixels from 0% to 100%. At the same time, the light generated by the light source can act through the light guide component and be concentrated and emitted from the light emitting surface, which can be used as a supplement to the mechanical pixels to achieve the display effect of color mechanical pixels. At the same time, the brightness and color of the light source can be controlled through the PCB board, providing rich color supplements for the mechanical pixels, so that the mechanical pixel display unit can achieve different rich visual display effects.

[0022] In an alternative embodiment, the light guide component includes a plurality of light guide columns, and the plurality of light guide columns are spaced apart around the axis of the light guide tube;

[0023] The mechanical pixel display unit includes a plurality of light sources, and the light sources correspond to the light guide columns one by one.

[0024] In an alternative embodiment, the driving part includes a servo motor, the light guide tube is formed with a notch, and the output end of the servo motor passes through the notch and is connected to the mechanical optical part.

[0025] In a third aspect, the present invention provides a display system, including a control module and a display module;

[0026] The display module includes a plurality of mechanical pixel display units of the foregoing embodiments, and the plurality of mechanical pixel display units are arranged in a predetermined order;

[0027] The control module is connected to the PCB board of each mechanical pixel display unit for respectively controlling the working states of the driving part and the light source in each mechanical pixel display unit.

[0028] In the above implementation process, each mechanical pixel display unit in the display system serves as a pixel point, and can form an image display with a color mechanical visual effect. Moreover, through the movement of the mechanical optical part in each mechanical screen display unit, the display image displayed by the display system can be conveniently changed, and a continuous dynamic display effect can be formed. The control module calculates the display effect that each pixel point should present at the current moment according to the image data, and respectively controls the light source and the driving part of each mechanical pixel display unit, so that each mechanical pixel display unit switches to the corresponding state.

[0029] In an alternative embodiment, the control module includes a processor, a driving control unit, and a light source control unit;

[0030] The processor is connected to the drive control unit and the light source control unit, and is configured to deliver drive adjustment data to the drive control unit and light source adjustment data to the light source control unit;

[0057] Next, the technical solutions in the present application will be described with reference to the drawings.

[0058] This embodiment provides a light guide assembly 10, which can solve the problem of poor imaging effect of the mechanically flipped display screen in the prior art.

[0059] As Figure 1 , Figure 1 is the elevation view of the light guide assembly 10 in this embodiment, Figure 2 is the top view of the light guide assembly 10 in this embodiment, Figure 3 is the axonometric view of the light guide assembly 10 in this embodiment, Figure 4 is Figure 2 the sectional view from the A-A perspective in

[0060] The light guide assembly 10 includes a light guide tube 100 and a light guide column 110. A light emitting surface 101 is formed on the end face of the light guide tube 100. The light guide column 110 is disposed on the tube wall of the light guide tube 100, and the light guide column 110 has a light incident position 111 for setting the light source 220.

[0061] Among them, the light generated by the light source 220 is reflected inside the light guide column 110, enters the tube wall of the light guide tube 100 and is emitted from the light emitting surface 101. In Figure 4 , the light source 220 is shown, and the arrows indicate the direction of the light reflected inside the light guide column 110 and the tube wall of the light guide tube 100.

[0062] The light generated by the light source 220 enters the light guide column 110. The light is reflected within the light guide column 110 until it enters the tube wall of the light guide tube 100. The light propagates within the tube wall of the light guide tube 100 and finally exits from the light emitting surface 101. The light guide column 110 is a solid columnar light guiding structure, and its principle is similar to that of an optical fiber. It has a low light loss ratio and can efficiently guide light, ensuring that there is no light leakage between the light source 220 and the light guide column 110, and enabling the light to effectively enter the light guide tube 100. The light guide tube 100 can be regarded as a plate-shaped light guiding structure connected end to end. The light enters the tube wall of the light guide tube 100 through the light guide column 110, which can solve the problem of side light leakage in the existing plate-shaped light guiding structure. Consistent with the light guiding principle of an optical fiber, the light guide tube 100 can make the light concentrate and exit from the light emitting surface 101, ensuring the light emitting effect; at the same time, the light guide tube 100 can be designed as a tubular structure of any shape to meet the design requirements.

[0063] It should be noted that the number of the light guide columns 110 is not limited. Refer to Figure 2 It can be seen that in this embodiment, the number of the light guide columns 110 is four, and the four light guide columns 110 are evenly arranged around the axis of the light guide tube 100. In other specific embodiments, the number of the light guide columns 110 can be set according to the light distribution requirements.

[0064] When the light guiding assembly 10 is applied to a mechanical flip display screen, the flip board in the mechanical flip display screen can be located in the light guide tube 100. The light emitted from its light emitting surface 101 can supplement the light for the mechanical flip display screen, improve the imaging effect of the mechanical flip display screen, and make the imaging rich and vivid.

[0065] At the same time, it should be noted that in Figure 1 and Figure 4 a circuit board (PCB board 230) is shown. The light source 220 can be a lamp bead, and the lamp bead is installed on the circuit board (PCB board 230). The circuit board (PCB board 230) can control the working state of the lamp bead to control the on / off of the lamp bead or the color of the light generated by the lamp bead according to the requirements. When the light guiding assembly 10 is applied to a mechanical flip display screen, the light guiding assembly 10 can supplement colors for the mechanical flip display screen, enabling it to display colorful and vivid images.

[0066] In the present disclosure, the light emitting surface 101 includes a light condensing structure 102. The light condensing structure 102 can condense the light, enabling the light to concentrate and exit from the light emitting surface 101. The light condensing structure 102 can be a matte frosted structure, a micro prism structure, or other structures that can achieve light condensation provided on the end face of the light guide tube 100.

[0067] In the present disclosure, the surface of the light guide tube 100 has a mirror polishing layer (not shown in the figure).

[0068] In the above implementation process, the surface of the light guide tube 100, that is, the inner and outer surfaces of the tube wall of the light guide tube 100, is mirror-polished to form a mirror-polished layer, which can ensure the efficient reflection of light inside the tube wall of the light guide tube 100; or after the mirror-polishing treatment, mirror electroplating / spraying of diffused silver paint can further improve the light reflection and diffusion efficiency inside the tube wall and ensure that the light does not leak out. It should be noted that when the light-emitting surface 101 is at the top end of the light guide tube 100, a mirror-polished layer can also be formed at the bottom end of the light guide tube 100.

[0069] Meanwhile, it should be noted that the outer surface of the light guide tube 100 can be subjected to outer decorative spraying, and the color of the outer decorative spraying can be selected according to requirements. That is, in one case, the light guide tube 100 can be subjected to three-layer surface treatment: 1. Mirror polishing; 2. Mirror electroplating / spraying of diffused silver paint; 3. Outer decorative spraying. Through the three-layer surface treatment, the light reflection and diffusion efficiency can be effectively improved and the appearance of the light guide assembly 10 can be beautified.

[0070] In the present disclosure, the light guide column 110 is conical, the bottom surface of the light guide column 110 forms a light incident position 111, and the light guide column 110 and the tube wall of the light guide tube 100 are gently connected through a transition zone 112.

[0071] In the above implementation process, the light guide column 110 is conical and is smoothly connected to the light guide tube 100 through the transition zone 112, which can effectively guide the light from the light incident position 111 to the tube wall of the light guide tube 100; at the same time, through the design of the size of the light guide column 110, the incident angle of the light (the incident angle is Figure 4 identified by N) is made as small as possible, so that the light is reflected in a spiral bending upward trajectory inside the light guide column 110 and the tube wall, achieving the effect of total reflection.

[0072] It should be noted that in the present disclosure, a concave lens structure 113 is formed at the light incident position 111. The concave lens structure 113 can be formed by the inner concavity of the top surface of the light guide column 110. It can not only accommodate the light source 220, but also further increase the proportion of the imported light, so that the light generated by the light source 220 is efficiently imported into the light guide column 110. It should be noted that after the light source 220 is installed, the lens arc surface of the concave lens structure 113 is perpendicular to the emission angle of the light generated by the light source 220 (the emission angle is Figure 4 identified by S), so as to maximize the guarantee that the light is imported into the light guide column 110.

[0073] It should be noted that in the present disclosure, the light guide column 110 and the light guide tube 100 are integrally formed, the bottom surface of the light guide column 110 and the bottom surface of the light guide tube 100 are in the same plane, and the bottom surfaces of both can be in contact with the circuit board (PCB board 230).

[0074] It should be noted that the light guide assembly 10 integrates the light guide column 110, the transition zone 112, the light guide tube 100, the concave lens structure 113, mirror polishing and mirror electroplating together. Its process structure is simple, the shape is small and compact. Without redundant assembly structures, it can achieve an efficient light guiding and emitting effect, save the assembly and debugging time, improve the efficiency, reduce the product cost and labor cost, and is easy to mass produce. Due to the small volume of the light guide assembly 10, it is suitable for miniature products and applicable to the mechanical pixel display unit 20.

[0075] It should be noted that the better the material of the light guide assembly 10 is for light conduction, the better. At the same time, in order to make the light emit uniformly from the light emitting surface 101 to form a uniform bright surface, additives conducive to light diffusion propagation (such as light diffusion powder) can be appropriately added to the material. At the same time, by appropriately increasing the light source 220, the light inside the light guide assembly 10 is made more uniform, so that the light emitted from the light emitting surface 101 is uniform and no dazzling light spots are generated.

[0076] It should be noted that the present disclosure also provides a mechanical pixel display unit 20. Refer to Figure 5 , Figure 5 which is a schematic diagram of the mechanical pixel display unit 20 in this embodiment.

[0077] The mechanical pixel display unit 20 includes a mechanical optical part 200, a driving part 210, a light source 220, a PCB board 230, and the light guide assembly 10 described above.

[0078] It should be noted that the mechanical pixel display unit 20 can be adjusted according to creative needs. For example, the light source 220 and the light guide assembly 10 can be cancelled, so that a more pure mechanical physical pixel performance can be obtained. The size, shape, quantity, installation method, creative structure and combination method of the PCB board 230, the light source 220 and the light guide assembly 10 can also be adjusted to help realize more creativity.

[0079] The light source 220 (such as an LED lamp bead), the driving part 210, and the light guide assembly 10 are connected to the PCB board 230, and the light source 220 is located at the light incident position 111 of the light guide column 110. The mechanical optical part 200 has a diffuse reflection surface, and the diffuse reflection surface corresponds to the light emitting surface 101. The driving part 210 is connected to the mechanical optical part 200 and drives the diffuse reflection surface to deflect relative to the light emitting surface 101.

[0080] It should be noted that in this embodiment, the mechanical optical part 200 is a flap 201, and the driving part 210 includes a servo motor 211.

[0081] It should be noted that the diffuse reflection surface refers to a surface with diffuse reflection characteristics and a high reflectance.

[0082] In the above implementation process, the mechanical pixel display unit 20 cooperates with the light source 220 and the light guide component 10 through the mechanical optical pixel principle for the imaging display of color mechanical pixels. Combining Figures 6 - 15 , Figures 6 - 10 FIG. Figures 6 - 10 is a schematic diagram of the mechanical optical part 200 (flap 201) at different positions from a lateral perspective in this embodiment. Figures 11 - 15 FIG. Figures 11 - 15 is a schematic diagram of the mechanical optical part 200 (flap 201) at different positions from a top-down perspective in this embodiment. It should be noted that Figures 6 - 10 In Figures 11 - 15 , in the diagrams belonging to the same regular sequence, the mechanical optical parts 200 (flaps 201) correspond to each other. Corresponding to each other means that the mechanical optical parts 200 (flaps 201) in the two diagrams are in the same position. The same regular sequence means Figure 6 corresponds to Figure 11 , Figure 7 corresponds to Figure 12 , Figure 8 corresponds to Figure 13 , Figure 9 corresponds to Figure 14 , Figure 10 corresponds to Figure 15 .

[0083] The mechanical optical pixel principle is as follows: 1. By controlling the angle of the mechanical optical part 200, the brightness of the specular reflection surface is precisely controlled, so as to precisely control the intermediate gray levels of the mechanical pixel from black to white; 2. By precisely controlling the angle, the visual duty cycle of the mechanical optical part 200 is controlled, so as to achieve the display effect of the size of the mechanical pixel from 0% to 100%; at the same time, the light generated by the light source 220 can act through the light guide component 10 and be concentrated on the light-emitting surface 101, which can be used as a supplement to the mechanical pixel to achieve the effect of color mechanical pixels; at the same time, through the PCB board 230, the brightness and color of the light source can be controlled, providing rich color supplements for the mechanical pixels, so that the mechanical pixel display unit 20 can achieve different rich visual display effects.

[0084] The flap 201 is connected to the output shaft of the servo motor 211 and is deflected relative to the light-emitting surface 101 of the light guide tube 100 under the drive of the servo motor 211, realizing the change of the brightness of the specular reflection surface and the change of the visual duty cycle. In other specific embodiments, the mechanical optical part 200 is not limited to a plate-like structure, and it can be a three-dimensional structure of any shape (such as a person, an animal, a geometric figure, etc.), as long as it can achieve the technical effect of changing the attitude and realizing the change of the brightness of the specular reflection surface of the three-dimensional structure and the change of the visual duty cycle.

[0085] Figure 18 , Figure 19 , Figure 20 , Figure 21respectively show a sequence of mechanical optical units 200 with a triangular columnar structure. In Figure 18 it is shown that the mechanical optical unit 200 is in a triangular columnar shape, the surface pointed by the "A" arrow in the figure is black, the surface pointed by the "B" arrow in the figure is white, and each mechanical optical unit 200 rotates precisely along the central axis of its columnar structure. Figure 19 , Figure 20 , Figure 21 respectively show that each mechanical optical unit 200 rotates precisely along the central axis of its columnar structure, and the mechanical pixel picture effect formed by multiple mechanical optical units 200.

[0086] Figure 22 show another sequence of mechanical optical units 200 with an irregular three-dimensional shape.

[0087] It should be noted that the rotation angle of the servo motor 211 can be precisely controlled. The higher the precision of the rotation angle, the richer the levels of the mechanical pixels. The direction, size, and torque of the servo motor 211 can also be arbitrary and can be adjusted in all directions according to the creative design requirements. The connection method between the servo motor 211 and the mechanical optical unit 200 is also arbitrary and can be adjusted in all directions according to the creative design requirements.

[0088] In this disclosure, the number of light sources 220 is the same as the number of light guide columns 110, both being four, and the four light sources 220 are arranged in the light guide column 110. It should be noted that the light guide tube 100 is formed with a notch, and the notch allows the output end of the servo motor 211 to pass through to be connected to the mechanical optical unit 200 (flap 201).

[0089] It should be noted that this disclosure also provides a display system 30, including a video input module 304, a control module 300, and a display module 310. Refer to Figure 16 and Figure 17 , Figure 16 which is the block diagram of the display system 30 in this embodiment. Figure 17 which is the schematic diagram of the display module 310 in this embodiment.

[0090] The display module 310 includes several mechanical pixel display units 20 of the foregoing embodiments, and several mechanical pixel display units 20 are arranged in a predetermined order. As Figure 8 shown, the predetermined order can be the order of four rows and four columns.

[0091] It should be noted that the display module 310 is formed by arranging and combining several mechanical pixel display units 20 in a certain manner. It can be regularly arranged, irregularly arranged, arranged in a plane, arranged in a three-dimensional manner, arranged in a straight line, or arranged in a curve. In short, the arrangement method of the mechanical pixel display units 20 of the display module 310 can be diversified and combined according to needs.

[0092] The control module 300 is connected to the PCB board 230 of each mechanical pixel display unit 20, and is used to control the working states of the driving part 210 and the light source 220 in each mechanical pixel display unit 20 respectively.

[0093] In the above implementation process, each mechanical pixel display unit 20 in the display system 30 serves as a pixel point, and can form an image display with a color mechanical vision effect. Moreover, through the movement of the mechanical optical part 200 in each mechanical screen display unit, the display image shown by the display system 30 can be conveniently changed, and a continuous dynamic display effect can be formed. The control module 300 calculates the image data, calculates the display effect that each pixel point should present at the current moment, and controls the light source 220 and the driving part 210 of each mechanical pixel display unit 20 respectively, so that each mechanical pixel display unit 20 switches to the corresponding state.

[0094] In the present disclosure, the control module 300 includes a processor 301, a driving control unit 302, and a light source control unit 303.

[0095] The processor 301 is connected to the driving control unit 302 and the light source control unit 303, and is used to send driving adjustment data to the control unit of the driving part 210 and send light source adjustment data to the light source control unit 303. The driving control unit 302 is connected to the driving part 210 and controls the driving part 210 based on the driving adjustment data. The light source control unit 303 is connected to the light source 220 and controls the light source 220 based on the light source adjustment data.

[0096] The video input module 304 is connected to the processor 301. The video input module 304 is used to receive video signals (such as various physical video signals from a graphics card, a camera, etc.) or video data (such as video files in various formats), and send the video signals or video data to the processor in the form of video data.

[0097] After receiving the video data, the processor 301 calculates the video data into servo motor control data and light source control data in real time, and sends driving adjustment data to the driving control unit 302 and sends light source adjustment data to the light source control unit 303 based on the servo motor control data and the light source control data, so as to adjust the working states of the driving part 210 and the light source 220 in the mechanical pixel display unit 20, and show a real-time continuous dynamic image to the observer, presenting an artistic dynamic effect like "mechanical impressionism".

[0098] It should be noted that the control module 300 can turn on / off the light source 220 or turn on / off the driving part 210 as needed to achieve the visual switching effect from mechanical + light to pure mechanical to pure light.

[0099] The inventor believes that the traditional "three major screens" (LCD screens, LED screens, and projection screens) have the following disadvantages:

[0100] 1. They do not have "physical decoration". In terms of the physical decoration requirements of buildings and spaces, high-precision clear imaging is optional, but "physical decoration" is essential. This is the market bottleneck and Achilles' heel of the traditional "three major screens".

[0101] 2. The picture disappears immediately after shutdown.

[0102] 3. They do not have "physical three-dimensional picture quality".

[0103] 4. After a system failure, the value of the product disappears completely.

[0104] However, the display system 30 provided by the present disclosure can solve the above disadvantages, enabling the display system 30 to have four characteristics: "physical decoration", the shutdown picture remains displayed, "physical three-dimensional picture quality", and still having decorative value even if the entire system breaks down.

[0105] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
