Description

Technical Field

[0001] This utility model relates to the field of driver board technology, and in particular to a naked-eye 3D driver board structure that is easy to install. Background Technology

[0002] The naked-eye 3D driver board is the core control component of a naked-eye 3D display system. Its core function is to achieve the technical goal of presenting stereoscopic visual effects without auxiliary equipment through precise signal processing and voltage regulation. Specifically, the driver board controls the working state of the liquid crystal cell or optical elements (such as slit gratings and lenticular lenses) in the display module through built-in raster pattern generation and image arrangement algorithms. For example, in a liquid crystal cell driving scenario, the driver board applies a voltage of a specific amplitude to both ends of the liquid crystal molecules, causing them to deflect at an angle, thereby changing the direction of light propagation. This, combined with the pixel arrangement of the display panel, enables dynamic switching between 2D and 3D display modes. This technical solution is widely used in advertising displays, medical imaging, industrial design, and other fields.

[0003] Existing glasses-free 3D driver boards rely on screws for installation. During installation, the driver board generally needs to be mechanically fixed by 3 to 4 screws penetrating the PCB board. The installation process requires professional tools and is time-consuming.

[0004] To address this, a naked-eye 3D driving board structure that is easy to install is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a naked-eye 3D driving board structure that is easy to install, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A glasses-free 3D driving board structure that is easy to install includes a glasses-free 3D driving board body and a mounting plate. The mounting plate is connected to the glasses-free 3D driving board body via a disassembly / assembly component, which is mounted on the mounting plate. The mounting plate is equipped with a mounting component for connecting to a device housing.

[0008] According to the present invention, a naked-eye 3D driving board structure that is easy to install includes a quick-release unit and a gear. The gear is rotatably mounted on the mounting plate via a rotating shaft. Two quick-release units are provided, and the two quick-release units are symmetrically arranged with the center of the gear as the center of symmetry.

[0009] Both quick-release units include a base plate, one end of which is fixedly connected to a rack that meshes with a gear. A connecting rod is fixedly installed on the top of the base plate, and several clips are fixedly connected to the connecting rod. One end of each clip has a clip interface. The side of the naked-eye 3D driving board body has a locking groove corresponding to each clip interface, and the clip interface can be inserted into the locking groove.

[0010] According to the present invention, a naked-eye 3D driving board structure that is easy to install is provided, wherein a handle bolt is rotatably provided on one of the base plates, and a threaded hole is provided on the mounting plate. When the card interface is engaged in the locking groove, the lower end of the handle bolt can be threadedly fixed in the threaded hole.

[0011] According to the present invention, a naked-eye 3D driving board structure that is easy to install is provided, wherein a guide slide is fixedly connected to the mounting plate, the base plate and the rack are slidably disposed in the guide slide, and the gear is disposed on the inner side of the guide slide.

[0012] According to the present invention, a naked-eye 3D driving board structure that is easy to install is provided, wherein the upper and lower ends of the card interface are provided with guide slopes.

[0013] According to the present invention, a naked-eye 3D driving board structure that is easy to install is provided, wherein the mounting components are provided in four sets, and the four sets of mounting components are respectively located at the four corners of the mounting plate. Each set of mounting components includes a connecting plate, a bolt, and a handle nut. The connecting plate has a waist hole, and the end of the connecting plate away from the waist hole has a mounting hole for connecting with the device housing. The upper end of the bolt passes through the waist hole and the mounting plate and is threadedly connected to the handle nut.

[0014] This utility model has at least the following beneficial effects:

[0015] Through the meshing transmission of gears and racks in the disassembly and assembly parts, the two quick-release units can move synchronously in opposite directions. The locking interface of the clip head engages with the locking groove of the drive board body, so that the installation and disassembly of the drive board can be completed quickly without relying on multiple screws and special tools, solving the problem of time-consuming and laborious traditional screw fixing methods.

[0016] After the handle bolt is engaged in the locking groove of the locking interface, it can be threaded into the threaded hole of the mounting plate to further secure the position of the base plate and prevent the locking structure from loosening unexpectedly; the guide slide body guides the movement of the base plate and the rack, avoids deviation, and ensures the stable operation of the quick-release unit.

[0017] The mounting plate has a slotted hole, allowing the plate to be adjusted within a certain range to accommodate installation requirements at different locations on the equipment housing. Attached Figure Description

Detailed Implementation

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figures 1 to 6 As shown, an embodiment of this utility model provides a naked-eye 3D driving board structure that is easy to install, including a naked-eye 3D driving board body 1 and a mounting plate 2. The mounting plate 2 is connected to the naked-eye 3D driving board body 1 through a disassembly and assembly component 3. The disassembly and assembly component 3 is installed on the mounting plate 2, and a mounting component 4 for connecting to the device housing is installed on the mounting plate 2.

[0029] In this design, mounting plate 2 acts as a bridge connecting the naked-eye 3D driver board body 1 and the device housing. The disassembly / removal component 3 allows for easy connection and separation between the naked-eye 3D driver board body 1 and mounting plate 2, facilitating the installation, disassembly, and maintenance of the driver board. Mounting component 4 securely fixes mounting plate 2 to the device housing, ensuring the stability of the entire driver board structure within the device.

[0030] Specifically, in this embodiment, the disassembly / assembly component 3 includes a quick-release unit and a gear 303. The gear 303 is rotatably mounted on the mounting plate 2 via a rotating shaft. Two quick-release units are provided, and the two quick-release units are symmetrically arranged with the center of the gear 303 as the center of symmetry. Both quick-release units include a base plate 301. A rack 302 is fixedly connected to one end of the base plate 301. The rack 302 meshes with the gear 303. A connecting rod 304 is fixedly installed on the top of the base plate 301. Several clips 305 are fixedly connected to the connecting rod 304. A clip interface 3051 is opened at one end of the clip 305. A locking groove 101 corresponding to the clip interface 3051 is opened on the side of the naked-eye 3D driving board body 1. The clip interface 3051 can be inserted into the locking groove 101.

[0031] When the base plate 301 of one of the quick-release units moves, the rack 302 connected to it moves accordingly. Since the rack 302 meshes with the gear 303, the gear 303 rotates, which in turn drives the rack 302 of the other quick-release unit, which is symmetrically arranged with it, to move synchronously in the opposite direction, thus achieving synchronous operation of the two quick-release units. When it is necessary to install the naked-eye 3D driving board body 1, push the base plates 301 of the two quick-release units to move towards each other, so that the card interface 3051 on the card head 305 aligns with and snaps into the locking groove 101 on the side of the naked-eye 3D driving board body 1, thereby fixing the naked-eye 3D driving board body 1 to the mounting plate 2; when disassembling, pull the base plates 301 of the two quick-release units in the opposite direction, so that the card interface 3051 disengages from the locking groove 101.

[0032] Specifically, in this embodiment, a handle bolt 306 is rotatably provided on one of the base plates 301, and a threaded hole is provided on the mounting plate 2. When the locking interface 3051 is engaged in the locking groove 101, the lower end of the handle bolt 306 can be threadedly fixed in the threaded hole.

[0033] After the card interface 3051 is engaged with the locking groove 101 for initial fixation, rotate the handle bolt 306 so that its lower end is screwed into the threaded hole on the mounting plate 2. As the handle bolt 306 is screwed in, it generates a pulling force on the base plate 301 towards the mounting plate 2, further securing the position of the base plate 301 and preventing the card interface 3051 from accidentally coming out of the locking groove 101 during use. This enhances the stability and reliability of the connection between the naked-eye 3D drive board body 1 and the mounting plate 2.

[0034] In this embodiment, a guide slide body 201 is fixedly connected to the mounting plate 2, and the base plate 301 and the rack 302 are slidably disposed in the guide slide body 201. The gear 303 is disposed on the inner side of the guide slide body 201.

[0035] The guide slide 201 provides guidance for the movement of the base plate 301 and the rack 302, ensuring that they maintain linear motion during movement and avoiding deviation or shaking, so that the two quick-release units can work more stably and smoothly.

[0036] Specifically, in this embodiment, guide slopes are provided at both the upper and lower ends of the card interface 3051.

[0037] When installing the naked-eye 3D driver board body 1, the guide slope on the card interface 3051 can play a guiding role. When the card head 305 approaches the locking groove 101, the guide slope contacts the edge of the locking groove 101, guiding the card interface 3051 to smoothly snap into the locking groove 101, reducing the installation difficulty and improving the convenience and efficiency of installation.

[0038] Specifically, in this embodiment, four sets of mounting components 4 are provided, and the four sets of mounting components 4 are respectively located at the four corners of the mounting plate 2. Each set of mounting components 4 includes a connecting plate 401, a bolt 402, and a handle nut 403. The connecting plate 401 has a waist hole 4011, and the end of the connecting plate 401 away from the waist hole 4011 has a mounting hole 4012 for connecting with the equipment housing. The upper end of the bolt 402 passes through the waist hole 4011 and the mounting plate 2 and is threadedly connected to the handle nut 403.

[0039] By placing four sets of mounting parts 4 at the four corners of the mounting plate 2, a fixing force can be applied evenly to the mounting plate 2, ensuring the stability of the connection between the mounting plate 2 and the equipment housing. The slotted holes 4011 on the connecting plate 401 allow for positional adjustment within a certain range to accommodate mounting holes at different positions on the equipment housing. During installation, the bolts 402 are passed through the slotted holes 4011 and the mounting plate 2, and then tightened with the handle nut 403 to achieve a fixed connection between the mounting plate 2 and the connecting plate 401; then, other connecting parts (such as screws) are used through the mounting holes 4012 to fix the connecting plate 401 to the equipment housing.

[0040] This embodiment also provides a specific example scheme and working principle of the naked-eye 3D driving board body 1 as follows: I. Specific example scheme of the naked-eye 3D driving board body

[0041] The naked-eye 3D driver board 1, as the core control component for realizing naked-eye 3D display functionality, must meet core requirements such as signal processing, timing control, and display driving. In this example, the naked-eye 3D driver board 1 adopts a multi-layer PCB structure, with dimensions of 150mm × 100mm × 2mm (length × width × thickness), and is compatible with mainstream naked-eye 3D display panels ranging from 10 to 27 inches. The specific hardware configuration is as follows:

[0042] 1. Core Control Module

[0043] It features a 1.2GHz ARM Cortex-A53 processor, integrating a dedicated glasses-free 3D image rendering unit. It supports real-time parsing of 2D / 3D video signals (compatible with HDMI 2.1 and DP 1.4 input interfaces) and can perform key algorithm processing such as disparity map calculation and pixel rearrangement. The processor is surrounded by 2GB of DDR4 memory and 16GB of eMMC flash memory for temporary storage of image data and firmware drivers.

[0044] 2.3D signal processing unit

[0045] It includes a dual-channel LVDS signal converter and an FPGA timing controller. The LVDS signal converter converts externally input video signals into low-voltage differential signals to reduce transmission interference; the FPGA timing controller generates precise pixel-driven timing based on the display panel resolution (supporting up to 4K@60Hz) and the type of naked-eye 3D technology (such as light barrier type, lenticular lens type) to ensure the synchronization of the alternating display of images for the left and right eyes.

[0046] 3. Power Management Module

[0047] It integrates a multi-channel DC-DC converter, supports a wide-range DC power supply of 12V input voltage, and outputs three stable voltages: 3.3V (powering the control chip), 5V (powering the interface circuit), and 1.8V (powering the FPGA core). It also has overcurrent and overvoltage protection functions to prevent damage to the driver board or display panel due to abnormal power supply.

[0048] 4. Interface Module

[0049] The board features a rich set of external interfaces:

[0050] Signal input interfaces: 1 HDMI 2.1, 1 DP 1.4, 1 USB Type-C (supports video input);

[0051] Display output interface: 1 eDP1.4 (connects to a glasses-free 3D display panel);

[0052] Control interfaces: 1 RS232 serial port (for firmware upgrades or external device control), 1 I2C interface (for connecting sensor modules);

[0053] Mechanical interface: Four sets of locking grooves 101 are symmetrically opened on the side edge (corresponding to the card head 305 of the disassembly and assembly part 3), with a groove depth of 2mm and a width of 5mm. The groove edge is rounded with a 0.5mm radius to fit the guide slope of the card interface 3051.

[0054] 5. Accessibility Components

[0055] Onboard temperature sensor (real-time monitoring of core chip temperature, automatically triggering frequency reduction protection when it exceeds 70℃), LED indicators (power indicator, signal indicator, fault alarm indicator), and an EEPROM storage chip (records display panel calibration parameters, such as parallax barrier position, lens focal length, etc.).

[0056] II. Working Principle of the Naked-Eye 3D Driver Board

[0057] The core function of the naked-eye 3D driver board 1 is to convert ordinary 2D video signals or native 3D signals into driving signals adapted to the naked-eye 3D display panel. Its workflow can be divided into the following five key steps:

[0058] 1. Signal reception and analysis

[0059] External video signals (such as 2D / 3D video output from set-top boxes or computers) are input to the driver board via HDMI / DP interfaces. First, the signal receiving circuit performs level conversion and protocol parsing, extracting video frame data (including pixel RGB values, horizontal and vertical sync signals, and resolution information), which is then temporarily stored in DDR4 memory. For 2D signals, the driver board automatically activates a real-time parallax generation algorithm, calculating the left and right eye parallax maps based on the display panel's physical parameters (such as viewing distance and panel size). For native 3D signals (such as left-right or top-bottom formats), the left and right eye image data are directly separated.

[0060] 2.3D Image Optimization Processing

[0061] The FPGA timing controller preprocesses the separated left and right eye images:

[0062] To address the jagged edge problem, a multi-phase interpolation algorithm is used for smoothing.

[0063] Based on the brightness data fed back by the ambient light sensor (which can be connected externally via I2C interface), the image gamma value is dynamically adjusted to ensure the consistency of 3D effect under different lighting conditions;

[0064] By combining the panel calibration parameters stored in the EEPROM, the pixel positions of the left and right eye images are finely adjusted to compensate for the parallax shift caused by panel assembly errors.

[0065] 3. Drive signal generation

[0066] The processed left and right eye image data are alternately output to the LVDS signal converter in a fixed timing sequence. After being converted into low-voltage differential signals, they are transmitted to the naked-eye 3D display panel via the eDP interface. Simultaneously, the driver board generates a synchronization control signal: if a light barrier panel is used, the synchronization signal controls the on / off state of the liquid crystal raster (the left-view raster is turned on when the left eye image is displayed, and switched to the right-view raster when the right eye image is displayed); if a lenticular lens panel is used, the timing of the control panel backlight is adjusted to ensure that the left and right eye images are focused on their respective viewing angles.

[0067] 4. Power supply and status monitoring

[0068] The power management module monitors the input voltage and the operating current of each circuit module in real time. When overcurrent (such as short circuit) or overvoltage (such as power fluctuation) is detected, the protection mechanism is immediately triggered, cutting off the power supply to the core chip and illuminating the fault indicator light. The temperature sensor collects the processor temperature every 100ms. When the temperature exceeds 70℃, the processor frequency is automatically reduced (from 1.2GHz to 800MHz) and an alarm message is output via the serial port to avoid performance degradation or hardware damage caused by high temperature.

[0069] 5. Adaptability Adjustment

[0070] Users can modify driver board parameters (such as 3D depth intensity and viewing distance range) via RS232 serial port or onboard buttons. The driver board will recalculate the disparity map and timing signals based on the modified parameters. For example, when the user selects the "Enhanced Depth" mode, the driver board will increase the disparity offset between the left and right eye images, making the 3D image more stereoscopic; if switched to the "Comfortable Viewing" mode, the disparity will be reduced to reduce visual fatigue.

[0071] III. Co-design with the installation structure

[0072] The locking groove 101 on the side of the naked-eye 3D driver board body 1 is not only a mechanical fixing point, but its position design also takes into account the electrical connection requirements: elastic conductive contacts are embedded inside the locking groove 101. When the card interface 3051 of the card head 305 is engaged in the locking groove 101, the conductive contacts contact the metal piece inside the card head 305, realizing the grounding connection between the driver board and the mounting plate 2, effectively reducing the impact of electromagnetic interference on 3D signal transmission. In addition, the gap between the edge of the driver board and the mounting plate 2 is designed to be 0.5mm, which not only avoids mechanical compression during installation, but also forms a natural heat dissipation channel through the air gap. Combined with the heat dissipation copper foil on the back of the driver board, the operating temperature can be controlled below 55℃.

[0073] The installation steps for the easy-to-install naked-eye 3D driving board structure of this utility model are as follows:

[0074] The mounting plate 2 is initially fixed to the equipment housing by the mounting part 4. The position of the mounting plate 2 is finely adjusted by the waist hole 4011 on the connecting plate 401. Then, the connecting plate 401 is fastened to the equipment housing by the mounting hole 4012 and screws.

[0075] The base plates 301 of the two quick-release units are pushed to move towards each other. Due to the guiding effect of the guide slide body 201, the base plates 301 and rack 302 can move in a stable straight line. At the same time, the gear 303 rotates to drive the two quick-release units to move synchronously.

[0076] When the card head 305 approaches the naked-eye 3D driving board body 1, the guide slope on the card interface 3051 guides the card interface 3051 to accurately engage in the locking groove 101 on the side of the naked-eye 3D driving board body 1.

[0077] Rotate the handle bolt 306 on one of the base plates 301 so that its lower end is screwed into the threaded hole on the mounting plate 2 to further secure the position of the base plate 301, thus completing the installation of the naked-eye 3D drive board body 1 and the mounting plate 2.

[0078] The disassembly steps are as follows:

[0079] First, turn the handle bolt 306 so that its lower end is unscrewed from the threaded hole on the mounting plate 2.

[0080] Pull the base plate 301 of the two quick-release units in the opposite direction so that they move in opposite directions. Under the guidance of the guide slide body 201, the two quick-release units move in opposite directions in sync, driving the card head 305 to move, so that the card interface 3051 disengages from the locking groove 101.

[0081] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
