[0001] This invention relates to the field of display screen technology, and in particular to a display screen surface treatment process and a display screen. Background Technology

[0002] With the continuous development of display technology, LED displays have achieved large-scale application in many fields due to their advantages such as high brightness, long lifespan, and wide viewing angle. At the same time, user demands for LED displays are no longer limited to basic dynamic content display; higher requirements are being placed on their decorative appearance when not powered, personalized pattern customization, and adaptability to multiple scenarios. Currently, the industry often creates surface patterns by processing the display mask. However, traditional methods are limited by process precision, often resulting in problems such as blurred pattern edges and poor adhesion. More importantly, existing processes rely heavily on physical tooling for positioning, which is inefficient and has large positioning deviations. This makes it difficult to accurately avoid LED beads on irregularly shaped or high-density modules, easily obstructing the light-emitting area and severely affecting the display effect. Summary of the Invention

[0003] The main objective of this invention is to provide a surface treatment process for a display screen and a display screen, aiming to solve at least one of the aforementioned technical problems.

[0004] To achieve the above objectives, the present invention proposes a display screen surface treatment process, which includes the following steps:

[0005] S1: Provides LED modules to be processed; S2: Capture the surface image of the LED module using a visual positioning system, and extract the position of the reference point on the LED module; S3: Based on the reference point position, a fixed coordinate is generated using layout software, and the fixed coordinate is adapted to the shape of the LED module; S4: Generate a target pattern on the surface of the LED module according to the solidification coordinates.

[0006] In one embodiment, step S4 specifically includes: S41: Obtain the coordinates of the LED beads in the LED module; S42: Generate a masking area based on the coordinates of the LED beads, and confirm the generation area of ​​the target pattern based on the masking area; S43: Generate the target pattern based on the generated region.

[0007] In one embodiment, step S42 includes: S421: A masking channel template is generated through digital modeling and rendering technology. The masking channel template is linked with the LED module's LED bead coordinate database and a pre-set avoidance structure is used to expose the LED beads. S422: Import the solidification coordinates and the masking channel template into the pattern generation system, and use the pattern generation system to confirm the generation area of ​​the target pattern on the surface of the LED module.

[0008] In one embodiment, the avoidance structure consists of multiple preset small holes, the positions of which correspond one-to-one with the positions of each LED bead in the LED module, so that the target pattern and the LED beads are superimposed without obstruction.

[0009] In one embodiment, in step S2, the visual positioning system includes an image acquisition unit, which stitches together images to cover the entire area of ​​the LED module, and establishes a correspondence between pixels and physical units using a multi-point calibration conversion method, wherein the accuracy of the multi-point calibration conversion is less than or equal to a preset accuracy.

[0010] In one embodiment, the LED module does not require a physical positioning fixture. Step S2 further includes: extracting the angle data of the LED module. Step S3 further includes: generating fixed coordinates based on the angle data using layout software, wherein the fixed coordinates are adapted to the shape of the LED module.

[0011] In one embodiment, the material used to generate the target pattern on the surface of the LED module is a photocurable material, which is rapidly cured by irradiation with light of a specific wavelength.

[0012] In one embodiment, the method of generating the target pattern on the surface of the LED module includes any one of printing, spraying, or coating.

[0013] The present invention also proposes a display screen, the display screen including a display screen surface treatment process. The display screen surface treatment process includes the following steps: S1: Provides LED modules to be processed; S2: Capture the surface image of the LED module using a visual positioning system, and extract the position of the reference point on the LED module; S3: Based on the reference point position, a fixed coordinate is generated using layout software, and the fixed coordinate is adapted to the shape of the LED module; S4: Generate a target pattern on the surface of the LED module according to the solidification coordinates.

[0014] In one embodiment, the display screen has three display control modes: non-display mode, half-display mode, and full-display mode. In the non-display mode, the display screen displays the color and gloss of the target pattern when the power is off. In the half-display mode, some LEDs of the display screen are lit, the unlit areas display the target pattern, and the lit areas display dynamic content. In the full-display mode, all LEDs are lit, the target pattern is hidden in the dark, and dynamic content is displayed.

[0015] The technical solution of this invention captures the surface image of an LED module using a visual positioning system and extracts the positions of reference points on the LED module. Based on the reference point positions, a fixed coordinate system is generated using layout software, and the fixed coordinate system is adapted to the shape of the LED module. A target pattern is then generated on the surface of the LED module according to the fixed coordinate system. This achieves precise positioning and generation of the pattern on the LED module surface, adapting to LED modules of different shapes and solving the problem of large pattern positioning deviations in traditional processes. Automated reference point extraction and coordinate generation reduce manual intervention, improve process efficiency, lay the foundation for precise avoidance of patterns and LED beads in subsequent processes, and improve the display effect of the screen.

[0022] With the continuous development of display technology, LED displays have achieved large-scale application in many fields due to their advantages such as high brightness, long lifespan, and wide viewing angle. At the same time, user demands for LED displays are no longer limited to basic dynamic content display; higher requirements are being placed on their decorative appearance when not powered, personalized pattern customization, and adaptability to multiple scenarios. Currently, the industry often creates surface patterns by processing the display mask. However, traditional methods are limited by process precision, often resulting in problems such as blurred pattern edges and poor adhesion. More importantly, existing processes rely heavily on physical tooling for positioning, which is inefficient and has large positioning deviations. This makes it difficult to accurately avoid LED beads on irregularly shaped or high-density modules, easily obstructing the light-emitting area and severely affecting the display effect.

[0023] This invention proposes a surface treatment process for display screens, aiming to solve the technical problem of rough screen surface affecting display effect.

[0024] Please see Figure 1 In one embodiment of the present invention, the surface treatment process of the display screen includes the following steps: S1: Provides LED modules to be processed; S2: Capture the surface image of the LED module using a visual positioning system and extract the position of the reference point on the LED module; S3: Based on the reference point position, the fixed coordinates are generated by the layout software and the fixed coordinates are adapted to the shape of the LED module; S4: Generate the target pattern on the surface of the LED module according to the fixed coordinates.

[0025] Specifically, the provided LED module mainly includes a PCB board and LED chips mounted on the PCB board. The PCB board can be made of epoxy resin substrate, and the LED chips are evenly arranged on the PCB board with a spacing of 0.3mm-1.5mm. The shape of the LED module can be a conventional rectangle or an irregular arc shape. The surface of the LED module can be processed to ensure that it is clean, free of stains and scratches, ensuring that subsequent patterns adhere firmly.

[0026] The visual positioning system can be an industrial-grade visual inspection system, consisting of an image acquisition module, an image processing module, and a data output module. It is installed directly above the operating platform and electrically connected to the operating system. The reference point is a pre-set positioning mark on the surface of the LED module. The image acquisition module captures images of the module surface using a high-definition camera. The image processing module uses edge detection and template matching algorithms to identify the reference point and accurately extract its pixel position in the preset coordinate system.

[0027] The layout software uses a proprietary alignment plugin. This software communicates with the vision positioning system, and after receiving the reference point position data, it automatically establishes a mapping relationship between the physical space of the module and the virtual space of the software. The fixed coordinates are the precise position parameters for pattern generation. A two-dimensional rectangular coordinate system is established with the lower left corner of the operating platform as the origin. The coordinate unit is mm. The coordinate distribution range is automatically adjusted according to the actual shape of the LED module (rectangular or irregular). The fixed coordinate range of the rectangular module coincides with the edge of the module, while the fixed coordinates of the irregular module are distributed along the contour curve of the module.

[0028] The target pattern is a user-customized decorative pattern or logo pattern. The pattern color adopts the RGB three-color system. The generation process is automatically completed by the pattern generation system. The pattern generation system is linked with the typesetting software. After receiving the fixed coordinates, it forms a continuous and complete pattern layer at the corresponding position on the surface of the LED module.

[0029] The visual positioning system is located above the LED module, and its acquisition range completely covers the entire area of ​​the LED module; the layout software is connected to the visual positioning system via a data cable to receive the reference point position data; the pattern generation system communicates with the layout software and performs pattern generation operations on the surface of the LED module based on the fixed coordinates.

[0030] This process enables precise positioning and generation of patterns on the surface of LED modules, adapting to LED modules of different shapes and solving the problem of large pattern positioning deviations in traditional processes. Through automated reference point extraction and coordinate generation, manual intervention is reduced, process efficiency is improved, and a foundation is laid for the precise avoidance of patterns and LED beads in the subsequent process, thereby improving the display effect of the screen.

[0031] The technical solution of this invention captures the surface image of an LED module using a visual positioning system and extracts the positions of reference points on the LED module. Based on the reference point positions, a fixed coordinate system is generated using layout software, and the fixed coordinate system is adapted to the shape of the LED module. A target pattern is then generated on the surface of the LED module according to the fixed coordinate system. This achieves precise positioning and generation of the pattern on the LED module surface, adapting to LED modules of different shapes and solving the problem of large pattern positioning deviations in traditional processes. Automated reference point extraction and coordinate generation reduce manual intervention, improve process efficiency, lay the foundation for precise avoidance of patterns and LED beads in subsequent processes, and improve the display effect of the screen.

[0032] Please see Figure 2 In one embodiment, step S4 specifically includes: S41: Obtain the coordinates of the LED beads in the LED module; S42: Generate the occlusion area based on the LED coordinates, and confirm the generation area of ​​the target pattern based on the occlusion area; S43: Generate the target pattern based on the generated region.

[0033] Specifically, the LED coordinates are the precise physical coordinates of the center of each LED on the LED module, pre-stored in the LED coordinate database, containing the x-axis coordinate, y-axis coordinate, and serial number information of each LED. The coordinates are obtained either through secondary imaging using a vision positioning system or by directly accessing preset coordinate data from module production, with a coordinate accuracy of ±0.01mm.

[0034] The masking area is the area on the LED module surface that needs to be avoided from the LED beads. Its shape matches the shape of the LED beads. For example, if the LED beads are round, the masking area is a circular area centered on the center of the LED beads, covering the entire light-emitting surface of the LED beads. The target pattern generation area is the remaining area on the LED module surface after removing the masking area. This area is continuous and complete to ensure the integrity and aesthetics of the pattern.

[0035] Based on the outline and range of the generated area, the pattern generation system automatically adjusts the pixel distribution of the target pattern, automatically crops the part of the pattern that overlaps with the masking area, retains the pattern part within the generated area, and finally forms a target pattern on the surface of the LED module that avoids all LED beads.

[0036] The LED coordinate database is connected to the pattern generation system. The masking area is generated based on the LED coordinates, and the target pattern generation area is determined by the masking area. These three elements form a linked "coordinate-masking-pattern" relationship. By accurately obtaining the LED coordinates and determining the masking area, the problem of the target pattern obscuring the LEDs is avoided, ensuring the normal light emission and display of the LED module. At the same time, the precise division of the target pattern generation area ensures the integrity of the pattern and its decorative effect, improving the practicality and aesthetics of the product.

[0037] Please see Figure 3 In one embodiment, step S42 includes: S421: A masking channel template is generated through digital modeling and rendering technology. The masking channel template is linked with the LED module's LED bead coordinate database and a preset avoidance structure is used to expose the LED beads. S422: Import the solidified coordinates and masking channel template into the pattern generation system, and confirm the generation area of ​​the target pattern on the surface of the LED module through the pattern generation system.

[0038] Specifically, CAD software can be used to perform the LED chip rendering operation. First, the 3D model file of the LED module is imported, and then the LED chip coordinate database is called to achieve real-time linkage with the CAD software through a data interface. The masking channel template is a digital template generated by the CAD software, containing the coordinate information and avoidance rules of the entire module. The preset avoidance structure is a hole-like structure that corresponds one-to-one with the LED chips. Digital modeling and rendering technology accurately delineates the distribution area of ​​each LED chip through digital modeling, generating masking data that perfectly matches the distribution of the LED chips, and storing it in the template in the form of spot color channels.

[0039] The pattern generation system can use a UV printing control system, which supports the import of TIF, PNG and other file formats. After importing the solidified coordinate file and the mask channel template file at the same time, the system automatically parses the coordinate data of both, uses the avoidance rules in the mask channel template as constraints, performs secondary calibration on the solidified coordinates, and removes coordinate points that fall within the avoidance structure. The final effective coordinate range is the generation area of ​​the target pattern.

[0040] The LED coordinate database and CAD software work in tandem. After the masking channel template is generated by the CAD software, it is imported into the pattern generation system along with the fixed coordinate file. Based on this data, the pattern generation system accurately confirms the generated area. Digital modeling and rendering technology enables precise and standardized generation of the masking channel template. The linkage with the LED coordinate database ensures real-time updates of the avoidance structure, preventing template failure due to changes in LED position. The synergy between the fixed coordinates and the masking channel template further improves the accuracy of the target pattern generation area, adapting to mass production scenarios and enhancing production consistency.

[0041] In one embodiment, the avoidance structure consists of multiple preset small holes, the positions of which correspond one-to-one with the positions of each LED bead in the LED module, so that the target pattern and the LED beads are superimposed without obstruction.

[0042] Specifically, the center coordinates of the pre-set small hole perfectly coincide with the center coordinates of each LED bead in the LED module, using a one-to-one correspondence setting to ensure that each LED bead has its own dedicated avoidance hole. Circular shapes are preferred to match the shape of mainstream round LED beads, but square, hexagonal, etc., can also be used for LED beads with special shapes. The edges of the shapes are smooth and burr-free to avoid affecting the aesthetics of the pattern. The diameter of the small hole is 0.02-0.05mm larger than the diameter of the corresponding LED bead. For example, when the diameter of the LED bead is 0.5mm, the diameter of the small hole is set to 0.53mm, ensuring that the LED bead is fully exposed while avoiding an excessively large small hole that would cause obvious gaps in the pattern.

[0043] Furthermore, depending on the LED arrangement density, a single-hole or multi-hole array can be selected. When the LED density is high, a multi-hole array is used, with the hole spacing matching the LED spacing. The preset holes are part of the masking channel template and are distributed at the corresponding LED coordinate positions on the masking channel template. When the template is imported into the pattern generation system, the hole area will shield the pattern generation operation, ensuring that the LED location is not covered by a pattern.

[0044] The circular small hole has strong adaptability and fits the shape of the LED bead very well, effectively avoiding the pattern from blocking the LED bead; the precise design of the small hole size balances the LED bead exposure requirements and the integrity of the pattern, preventing problems such as the LED bead being blocked or the pattern having too large gaps, and ensuring the unity of the LED module display effect and decorative effect.

[0045] In one embodiment, in step S2, the visual positioning system includes an image acquisition unit, which stitches together images to cover the entire area of ​​the LED module, and uses a multi-point calibration conversion method to establish the correspondence between pixels and physical units. The accuracy of the multi-point calibration conversion is less than or equal to a preset accuracy.

[0046] Specifically, the image acquisition unit is electrically connected to the image acquisition module of the vision positioning system, and they work together to capture images of the LED module surface. Multi-point calibration transformation is the core algorithm of the image processing module of the vision positioning system, performing coordinate transformation operations based on the image data acquired by the cameras. The collaborative shooting by multiple cameras eliminates the blind spots of a single camera, ensuring the comprehensiveness of the extracted reference points. The multi-point calibration transformation method significantly improves the accuracy of coordinate transformation, providing reliable basic data for the accurate generation of subsequent fixed coordinates, and guaranteeing high-precision pattern positioning.

[0047] In one embodiment, the LED module does not require a physical positioning fixture. Step S2 further includes: extracting the angle data of the LED module; Step S3 further includes: generating fixed coordinates based on the angle data using layout software, and the fixed coordinates are adapted to the shape of the LED module.

[0048] Specifically, this application abandons the traditional mechanical clamping method and relies on the precise positioning of a vision positioning system to replace the constraint of the clamp. The LED module is placed directly on the operating platform, and the surface of the operating platform can be covered with an anti-slip silicone pad to prevent the module from sliding during processing. There is no need to customize special clamps for modules of different shapes. The angle data is the rotation angle of the LED module relative to the printing reference direction. It is extracted by identifying the relative positional relationship of at least two reference points through the vision positioning system, and calculating the angle between the line connecting the reference points and the horizontal reference line of the operating platform. The angle measurement accuracy is ±0.01°. For example, if the angle between the line connecting the two reference points and the horizontal reference line is 2° clockwise, then the angle data of the module is 2°. After receiving the angle data, the layout software performs rotation calibration on the initially generated solidified coordinates through a coordinate rotation algorithm. The calibrated solidified coordinates are perfectly matched with the actual placement angle of the LED module, ensuring that the pattern generation direction is parallel to the edge of the module. Of course, in other embodiments, fixtures can also be used to improve positioning stability, and this is not specifically limited.

[0049] The visual positioning system simultaneously extracts reference point position data and angle data, both of which are transmitted synchronously to the layout software. Based on these two types of data, the layout software collaboratively generates fixed coordinates adapted to the shape and placement angle of the LED module. The LED module is placed on the anti-slip silicone pad of the operating platform without additional clamping constraints. The fixture-free design reduces the production cost of dedicated fixtures, improves the flexibility of module placement, and adapts to LED modules of any shape. The extraction of angle data and the rotation calibration of the fixed coordinates solve the problem of pattern offset caused by module tilt, further improving the adaptability of the process and the accuracy of pattern positioning, and reducing the time cost of manually adjusting the module position.

[0050] In one embodiment, the material used to generate the target pattern on the surface of the LED module is a photocurable material, which is rapidly cured by irradiation with light of a specific wavelength.

[0051] Specifically, photocurable materials are mainly composed of acrylate monomers, photoinitiators, pigments, and additives. The colors of photocurable materials can be customized to the full RGB color system. Before curing, they are in a liquid state with a viscosity of 20-30 mPa. The cured pattern layer exhibits a light transmittance ≥85%, a hardness ≥3H, abrasion resistance ≥500 cycles, and UV aging resistance ≥1000 hours. Curing can be achieved using a 100W UV lamp with a specific wavelength, an irradiation distance of 10-15cm, and a curing time of 3-5 seconds. No volatile harmful substances are generated during the curing process, making it environmentally friendly and pollution-free. Depending on the application scenario, matte UV-curable materials (surface gloss ≤10°) or high-gloss UV-curable materials (surface gloss ≥80°) can be selected. For outdoor applications, weather-resistant UV-curable materials can be used to enhance the pattern's resistance to rain and sun exposure.

[0052] Photocurable materials are characterized by fast curing speed and environmental friendliness, which greatly improves production efficiency. The pattern layer formed after curing has good light transmittance, wear resistance and weather resistance. It does not affect the light-emitting effect of LED modules and can ensure that the pattern does not fade or peel off for a long time, thus extending the service life of the product.

[0053] In one embodiment, the method of generating the target pattern on the surface of the LED module includes any one of printing, spraying, or coating.

[0054] Specifically, UV printing is the preferred method for generating target patterns, suitable for creating intricate designs with clear edges and uniform color. Extended options include inkjet printing and laser printing; inkjet printing is suitable for large-area patterns, while laser printing is suitable for high-precision line patterns. Spraying can utilize a color painting process, diluting the UV-curable material before spraying, suitable for generating large-area solid color or gradient patterns. Extended options include electrostatic spraying, which improves ink adhesion uniformity and reduces material waste. Lamination can employ a film-applied process, where the target pattern is pre-printed on a 0.1mm thick PET translucent film with a light transmittance ≥90%. The PET film is then applied to the LED module surface using UV adhesive, and the adhesive is cured by UV light after lamination. Extended options include self-adhesive film application, suitable for scenarios requiring temporary pattern changes, facilitating disassembly and replacement.

[0055] All three target pattern generation methods described above are based on the generation area determined by the curing coordinates. In printing and spraying, the pattern generation system directly applies the material to the LED module surface; in lamination, the PET film is fixedly connected to the LED module using UV adhesive. These diverse pattern generation methods adapt to different pattern types and production needs: UV printing is suitable for fine patterns, spraying for large-area patterns, and lamination for temporary replacement scenarios. Users can flexibly choose according to their cost budget and product requirements, improving the versatility and market adaptability of the process.

[0056] The present invention also proposes a display screen, which is made by the aforementioned display screen surface treatment process. The specific structure of the display screen surface treatment process is as described in the above embodiments. Since the display screen adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0057] In one embodiment, the display screen has three display control modes: non-display mode, half-display mode, and full-display mode. In non-display mode, the display screen displays the color and gloss of the target pattern when the power is off. In half-display mode, some LEDs of the display screen are lit, the unlit areas display the target pattern, and the lit areas display dynamic content. In full-display mode, all LEDs are lit, the target pattern is hidden in the dark, and dynamic content is displayed.

[0058] Specifically, the display screen consists of an LED module, a target pattern layer, or, on top of that, a transition layer and / or a protective layer. The LED module is the core light-emitting unit, the target pattern layer is located on the outer surface of the LED module, the transition layer can cover the outside of the target pattern layer, and the protective layer is the outermost layer. The LED module serves as the substrate, the target pattern layer is tightly attached to the outside of the LED module's display layer, the transition layer can be bonded to the surface of the target pattern layer by means of lamination, and the protective layer can be applied to the outside of the transition layer by spraying or other processes. All layers are tightly bonded together without bubbles or gaps.

[0059] The transition layer is made of silicone, with a thickness of 0.02mm-0.08mm, providing cushioning and protection. The protective layer is made of polyurethane, with a thickness of 0.05mm-0.15mm, offering scratch resistance, water and dust resistance. Furthermore, depending on the application scenario, flexible LED modules can be used to create a flexible display screen, suitable for curved and sculpted installations; transparent LED modules can also be used to create a transparent display screen, enhancing the sense of openness in a space.

[0060] The aforementioned target pattern layer is manufactured using the aforementioned display screen surface treatment process and exists attached to the LED module. The transition layer and protective layer protect both the target pattern layer and the LED module, extending the lifespan of the display screen. This display screen combines LED display functionality with decorative functionality, solving the problem of a monotonous surface when traditional display screens are not powered on. The synergistic effect of each layer ensures that the display screen has both excellent display effects and superior durability and environmental adaptability, making it widely applicable in shopping malls, exhibition halls, outdoor advertising, and other scenarios.

[0061] The three display modes are as follows: Non-display mode: The display screen is off, and the LEDs are not emitting light. In this mode, ambient light shines on the target pattern layer, and the pattern layer displays its own color and gloss through the reflection and refraction of light, making the pattern clearly visible and serving a decorative purpose. In this mode, the color saturation of the target pattern layer is ≥80%, resulting in high pattern recognition.

[0062] Semi-display mode: The control system illuminates a portion of the LEDs. The light emitted from the illuminated LEDs penetrates the target pattern layer, displaying preset dynamic content (such as animation or scrolling text). The LEDs in the unilluminated areas remain silent, and the target pattern layer retains its original decorative effect. This creates visual synergy, combining dynamic display with static decoration. The brightness of the illuminated areas is ≥500 cd / m², providing a clear contrast with the unilluminated areas.

[0063] Full Display Mode: The control system illuminates all LEDs, resulting in high-intensity light. Due to its translucent design, the target pattern layer is hidden behind the strong light and is invisible to the naked eye. The display screen shows dynamic content (such as videos and high-definition images) in full screen. In this mode, the full-screen brightness of the display screen is ≥800cd / m², the contrast ratio is ≥1000:1, and the display effect is clear and realistic.

[0064] The three display modes are switched via the display's control system, which is electrically connected to the LED module's lamp bead drive circuit. By controlling the number and brightness of the illuminated lamp beads, different modes are switched. The light transmittance design of the target pattern layer is key to achieving mode switching; its transmittance can be adjusted according to the lamp bead brightness. The design of the three display modes enriches the display's functionality: the non-display mode is suitable for decorative needs during off-peak hours, the half-display mode is suitable for scenarios requiring both information display and decoration, and the full-display mode is suitable for high-definition content playback. Mode switching is simple, improving the user experience and broadening the display's application range.

[0065] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
