Technical Field

[0002] LED optoelectronic glass is a product that perfectly combines LED light sources with glass. Patterns can be pre-designed inside the glass, and their changes can be controlled later using DMX (Digital Multi-channel Rendering) fully digital intelligent technology. This allows for free control over the brightness and variations of the LED light source. More precisely, LED optoelectronic glass is a type of LED-embedded art glass. Existing LED optoelectronic glass includes a base layer, an intermediate layer, and a cover layer. The base layer is conductive glass with conductive lines and power interfaces. LED light emitters are placed within the conductive lines, arranged according to the desired pattern and effect. The intermediate layer is a PVB (polyvinyl butyral) film located between the base layer and the cover layer, and the base layer, intermediate layer, and cover layer are bonded together through special treatment.

[0073] like Figure 1-9 As shown, in a first aspect, the present invention provides a photoelectric glass module 1 supporting double-sided display, comprising:

[0074] case;

[0075] A glass-based circuit board, which is placed inside the housing, includes a first glass-based circuit board 10, a second glass-based circuit board 20, and a flexible PVB film 30. The first glass-based circuit board 10 and the second glass-based circuit board 20 are bonded together by the flexible PVB film 30.

[0076] The first glass-based circuit board 10 includes a first FPC flexible circuit board 801 and a first LED lamp group 101. The first LED lamp group 101 includes a plurality of first LEDs 1011. The plurality of first LEDs 1011 are distributed in an array on the first glass-based circuit board 10, and all first LEDs 1011 are electrically connected to the first FPC flexible circuit board 801.

[0077] The second glass-based circuit board 20 includes a second FPC flexible circuit board 802 and a second LED light group 201. The second LED light group 201 includes a plurality of second LEDs 2011. The plurality of second LEDs 2011 are distributed in an array on the second glass-based circuit board 20. All second LEDs 2011 are electrically connected to the second FPC flexible circuit board 802. The second LED light group 201 and the first LED light group 101 are arranged alternately.

[0078] The PCB circuit board 40 is soldered to the first FPC flexible circuit board 801 and the second FPC flexible circuit board 802. The PCB circuit board 40 also includes a main control chip and a driving circuit. The main control chip is electrically connected to the driving circuit. The driving circuit includes a first driving circuit and a second driving circuit. The first driving circuit is used to drive the first LED light group 101, and the second driving circuit is used to drive the second LED light group 201.

[0079] In some embodiments, the optoelectronic glass module 1 further includes a terminal protection base, which includes a terminal top cover 1001, a terminal base 1003, and a terminal side cover 1002. The PCB circuit board 40 is placed in the enclosed space formed by the terminal top cover 1001, the terminal base 1003, the terminal side cover 1002, and the glass-based circuit board.

[0080] In some embodiments, the optoelectronic glass module 1 further includes an insulating pad 50, such as Figure 4As shown, the PCB circuit board 40 includes signal pads 401, positive pads 402, negative pads 403, and a first positioning hole 404. The insulating pad 50 includes soldering positions 501, wire insertion positions 502, and a second positioning hole 503. The positions of the first positioning hole 404 and the second positioning hole 503 correspond to each other, so that the PCB circuit board 40 and the insulating pad 50 can be better assembled together. Preferably, the insulating pad 50 includes a first pad 60 and a second pad 70. The first pad 60 is disposed on the solder joint on the side where the first FPC flexible circuit board 801 is soldered to the PCB circuit board 40, and the second pad 70 is disposed on the solder joint on the side where the second FPC flexible circuit board 802 is soldered to the PCB circuit board 40.

[0081] Preferably, the dimensions of the first glass-based circuit board and / or the second glass-based circuit board are 1200 mm in length, 800 mm in height, and 6 mm in thickness.

[0082] Preferably, the second LED light group and the first LED light group are staggered, wherein the distance from the edge of the first LED light group is 10mm and the distance from the edge of the second LED light group is 20mm.

[0083] Preferably, the thickness of the flexible PVB film is 2.28 mm.

[0084] Preferably, the back of the optoelectronic glass module 1 is also provided with a plug 90, which extends out of the screen of the module.

[0085] In the fabrication of the optoelectronic glass module 1 of this application, a double-layer circuit design approach is adopted, which allows for the design of two identical LED optoelectronic glass circuits on both sides. These circuits are then mounted according to the general PCBA process. After completion, the two glass-based circuit boards with the intelligent IC internally controlled LED light groups are independent control circuits. This scheme utilizes the high transparency of the glass to interlock without interfering with each other. After interlocking, the first LED light group and the second LED light group are staggered, and the positions of the first LED light and the second LED light do not overlap. This enables the front and back sides of the optoelectronic glass module to be controlled independently and to emit light normally.

[0086] During the assembly process, two semi-finished optoelectronic glass pieces with LED beads and external circuit components mounted on them can be assembled according to the production process of ordinary optoelectronic glass. A flexible PVB film with a thickness of 2.28mm is used in the middle. The main manufacturing process of double-sided display optoelectronic glass is completed by vacuuming and laminating in an autoclave. Finally, the laminated optoelectronic glass is fitted with specially designed waterproof cable outlets to realize external control connection and complete the production of optoelectronic glass module with double-sided display function.

[0087] The display control system of this application mainly includes a power supply and a PCB circuit board. The PCB circuit board includes a main control chip (e.g., a high-performance chip using an ARM architecture with a main frequency of over 1GHz, possessing multi-channel data processing capabilities, and capable of processing front and back display data simultaneously). In the glass-based circuit scheme, the LED beads can adopt a single-line zero-code control method (which can achieve independent and precise adjustment of the brightness, color, etc. of LED dot matrix in different areas, with an adjustment accuracy of 256 levels of grayscale control). The LED bead spacing of the photoelectric glass for the front display is 20mm, using high color rendering index and high brightness LED beads, with a color rendering index Ra≥90, a brightness of 10-15 lumens per bead, and a light output uniformity of over 97.5%. The photoelectric glass for the back display has a similar configuration to the photoelectric glass for the front display. The main control display system power supply is connected to the front and back photoelectric glass displays via the Gx16-6 terminal block, forming a display control system to achieve precise control of the double-sided display. Each main control display system power supply is connected to the corresponding double-sided photoelectric glass screen on the railing. Multiple main control display system power supplies are connected and communicated with each other via network cables. Connecting the network cable to the main control display system enables the double-sided video playback function.

[0088] In a second aspect, this utility model provides a double-sided display photoelectric glass railing, comprising:

[0089] Multiple columns are distributed along an axis, and each column is provided with a groove;

[0090] The optoelectronic glass module is as described in the first aspect of this application. The optoelectronic glass module is snapped into the grooves of two adjacent columns, and the columns and the optoelectronic glass module are detachably locked by fasteners.

[0091] Optionally, a rubber pad is also provided in the gap between the optoelectronic glass module and the column.

[0092] Optionally, the columns may also be provided with transverse guardrails in the axial direction.

[0093] In this application, the glass used for the glass-based circuit board can be a special anti-reflective glass or an AR-coated high-transmittance glass, whose optical parameters have been carefully designed and optimized. The visible light transmittance of the glass is as high as 85% or more, ensuring that the displayed content can be clearly seen from both sides when displaying on both sides. It has good transparency and visually approaches ordinary transparent glass, achieving the display function without causing obvious obstruction to the surrounding environment.

[0094] The front reflectivity of the light intensity of the glass-based circuit board is strictly controlled to within 10%. Specifically, under the illumination of light with a wavelength range of 400-700nm (covering the entire visible light spectrum), the average reflectivity does not exceed 8%. This low reflectivity effectively solves the problem of light pollution caused by the interference between the light from both sides when playing media videos on both sides at the same time, and avoids image ghosting, blurring and interference with the viewer's vision caused by reflected light.

[0095] The glass in the glass-based circuit board has a refractive index of about 1.5-1.6, which is well matched with the refractive index of air and surrounding display components. This can minimize the refraction and reflection loss of light at the glass interface, ensure the stability of the light path when the light propagates inside the glass and when it enters and exits the glass, thereby achieving a clear and high-quality double-sided display effect.

[0096] The glass in the glass-based circuit board has a Mohs hardness of 6-7, giving it excellent wear and scratch resistance. This allows it to maintain a smooth surface and unaffected display quality over long-term use. Furthermore, its impact resistance meets relevant building safety standards; for example, it can withstand the impact of a steel ball of a certain mass (e.g., 5kg) falling freely from a specific height (e.g., 1m) without breaking, ensuring that the railing reliably performs its protective and isolating function while still providing display capabilities.

[0097] Based on the actual application scenarios and structural strength requirements of the railing, the overall thickness of the optoelectronic glass module is usually selected to be between 10-14mm of laminated glass. This ensures sufficient mechanical strength to support the display module and withstand daily external forces, while also achieving the best balance in optical performance for double-sided display.

[0098] In this application, the uprights can be made of high-strength stainless steel with a yield strength of not less than 200MPa and a thickness selected between 3-6mm depending on the railing size. The rubber pads have a Shore hardness between 40-60, providing good elasticity and shock absorption performance, and a thickness of 3-5mm. The locking fasteners can be stainless steel bolt sets (bolt specifications conforming to national standards, such as M8-M12, with a strength grade of 8.8 or higher). Fine-tuning screws with a pitch of 0.5-1mm can also be provided for precise adjustment of the screen's flatness. The screen is inserted into the groove of the upright, the gaps are filled with rubber pads, and it is secured with bolts. The fine-tuning screws are then used to adjust the flatness of the screen, ensuring stable installation and good display effect.

[0099] In this application, after multiple optoelectronic glass modules are implanted into the grooves of multiple adjacent columns, they can be sequentially connected to the display control system and the communication cable can be connected via a single-ended connection cable. This allows for the identification of display images from different channels and the display of edited video files on both sides.

[0100] When the double-sided photoelectric glass railing is powered on, the main control chip in the display control system outputs high and low level control signals to the LED lamp bead matrix circuit (i.e., the first driving circuit or the second driving circuit) according to the set instructions. This, in turn, drives the LED light strips (i.e., the first LED light group or the second LED light group) and light guide plate on the front or back, so that the corresponding image or video content is displayed on the photoelectric glass. Users can freely switch between single-sided and double-sided display modes through the electronic control system and can control the display content in real time to meet the display needs of different scenarios.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
