Description

Technical Field

[0001] This utility model relates to the field of display accessories technology, specifically to a frameless LED display glass. Background Technology

[0002] In the current display technology field, LED display glass is widely used in commercial displays, building curtain walls, interior decoration and other scenarios because it combines light transmission and display functions. The market's requirements for its appearance integrity, ease of installation and display effect continue to increase.

[0003] Existing LED display glass typically requires an additional frame structure to fix and encapsulate core components such as the glass substrate, diffuser plate, and LCD screen. The presence of the frame not only disrupts the overall visual effect of the display but also increases the assembly complexity and overall thickness of the product, making it difficult to meet the demands of modern design for "borderless" and "lightweight" designs. Furthermore, some display glass solutions without a clearly defined frame often use adhesive bonding or complex snap-fit ​​structures to fix internal components, resulting in low component positioning accuracy and a tendency for components to detach over long-term use. Additionally, the circuit layout and light reflection design on the back of the substrate are often inadequate, leading to low light utilization from the LED chips, uneven display brightness, and high energy consumption, failing to balance structural stability and display performance.

[0004] Therefore, there is an urgent need for an LED display glass structure that requires no additional frame, has reliable component fixation, and can optimize display effects, in order to solve the above-mentioned defects in the existing technology. Utility Model Content

[0007] Furthermore, the opening of the inner stepped side groove faces the central axis of the receiving cavity, while the opening of the outer stepped side groove faces away from the central axis of the receiving cavity.

[0008] Furthermore, the conductive line layer is fabricated on the back side of the glass substrate by a coating or printing process, and its line width and spacing are 3-6 μm.

[0012] Furthermore, the glass substrate is chemically strengthened glass.

[0013] The beneficial effects of this utility model are: 1. Break through the limitations of bezels and enhance visual integrity: The glass substrate is molded as a whole, eliminating the need for additional bezels, eliminating the sense of screen fragmentation, and enhancing the immersive visual experience and appearance competitiveness.

[0014] 2. Easier assembly and maintenance: The inner and outer stepped side grooves precisely fix the diffuser plate and LCD screen, replacing glue / complex clips, reducing assembly steps, lowering costs, and facilitating subsequent disassembly and maintenance, avoiding the risk of components falling off.

[0015] 3. A win-win situation for energy saving: The reflective layer on the back improves the utilization rate of LED light, solves the problem of uneven brightness, and reduces light loss.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This invention provides a frameless LED display glass.

[0025] In this embodiment, refer to Figure 1-2 The frameless LED display glass includes a glass substrate 1, which is integrally formed into a substrate body 2 and a surrounding glass section 3 by a hot bending process. The surrounding glass section 3 is perpendicular to the substrate body 2, and the substrate body and the surrounding glass section together form a receiving cavity. The inner sidewall of the surrounding glass section is provided with an inwardly protruding inner stepped side groove 4 for fixing a glass diffuser plate. Its outer sidewall is provided with an outwardly protruding outer stepped side groove 5 for mounting a liquid crystal display screen. A conductive circuit layer 6, a black film layer 7, and a reflective layer 8 are sequentially arranged on the back of the substrate body. LED beads 9 are arranged on the reflective layer 8.

[0026] In the above technical solution, the glass substrate is integrally formed into a substrate body and a vertical enclosure glass part through a hot bending process, and the two are used to enclose and form a space to accommodate the core components; the glass diffuser plate is fixed by the physical limiting structure of the inner stepped side groove on the inner side of the enclosure glass part, and the liquid crystal display screen is positioned and installed by the outer stepped side groove on the outer side; a conductive circuit layer (to power the LED), a black film layer (to shield the circuit and avoid light interference), and a reflective layer (to reflect LED light) are sequentially set on the back of the substrate, and LED beads are arranged on the reflective layer to form a complete display function chain.

[0027] Thus, component encapsulation can be completed without additional borders, eliminating the visual disruption caused by borders; stepped edge grooves enable precise component fixation, replacing traditional glue / clips and improving assembly reliability; multi-layer structure optimizes light utilization and circuit layout, solving problems of uneven brightness and high energy consumption, while the one-piece molded substrate enhances the overall structural strength and extends product life.

[0028] Specifically, the opening of the inner stepped side groove faces the central axis of the receiving cavity, while the opening of the outer stepped side groove faces away from the central axis of the receiving cavity.

[0029] In this embodiment, the inner stepped side groove opening is oriented towards the central axis of the receiving cavity to ensure that the glass diffuser plate can be inserted into and limited from the inside of the cavity, preventing it from falling outward; the outer stepped side groove opening is oriented away from the central axis of the receiving cavity, so that when the liquid crystal display screen is installed from the outside, the force direction is consistent with the groove limiting direction, ensuring a stable installation.

[0030] The cavity in this application refers to the three-dimensional space jointly enclosed by the glass substrate body and the surrounding glass part after being hot-bent.

[0031] Specifically, the conductive line layer is fabricated on the back side of the glass substrate by a coating or printing process, and its line width and spacing are 3-6 μm.

[0032] In this embodiment, a conductive circuit layer is fabricated using a coating or printing process, which can form a fine circuit on the back of the glass substrate; the line width and spacing are limited to 3-6μm, which allows for the arrangement of more lines in a limited space, meeting the dense power supply requirements of LED beads, and the process is mature and easy to mass-produce.

[0033] Specifically, the black film layer covers the conductive circuit layer, and its material is black ink or black photosensitive adhesive.

[0034] In this embodiment, a black film layer covers the conductive circuit layer. The black material blocks the light of the circuit itself, preventing the circuit reflection from interfering with the transmission of LED light. Black ink or black photosensitive adhesive is selected. Both materials have good adhesion, can be tightly bonded to the conductive circuit layer, and are easy to form through printing, coating and other processes.

[0035] Specifically, the reflective layer is a white ink layer or a metal plating layer.

[0036] In this embodiment, the reflective layer is selected from either a white ink layer (utilizing the high diffuse reflection characteristics of white light) or a metal plating layer (utilizing the high specular reflection characteristics of metal light). Both materials can reflect the scattered light emitted by the LED beads to the display surface, reducing the loss of light to the back of the substrate.

[0037] Specifically, the glass diffuser plate is fitted into the inner stepped side groove, and its bottom surface has a predetermined distance from the surface on the substrate body where the reflective layer is disposed; the liquid crystal display screen is fitted into the outer stepped side groove.

[0038] In this embodiment, the glass diffuser plate is fitted into the inner stepped side groove, with a predetermined distance between its bottom surface and the surface of the reflective layer, providing diffusion space for the LED light and preventing the diffuser plate from being too close to the reflective layer, which would prevent the light from being unable to diffuse sufficiently; the liquid crystal display screen is fitted into the outer stepped side groove, and the groove body limits the precise alignment with the glass substrate.

[0039] Specifically, the glass substrate is chemically strengthened glass.

[0040] In this embodiment, the glass substrate is chemically strengthened glass, which forms a compressive stress layer on its surface through an ion exchange process, significantly improving the glass's impact resistance, bending strength, and surface hardness, and exhibiting superior mechanical properties compared to ordinary glass.

[0041] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
