Description

[0001] Technical field

[0002] The invention relates to display means and interior structures, in particular to mirror panels with integrated video display for domestic and commercial use, including rooms with limited ventilation and / or high humidity.

[0003] Technology Level

[0004] There are known solutions that place the display behind a translucent mirror glass, providing moisture protection and a general layout, but do not reveal reliable passive thermal technology without fans with heat paths through the glass and the housing, do not provide an intra-package location of the mirror layer and service access without dismantling the glass, as well as integration with a “smart home” through a rear IR duplicating sensor.

[0005] A technical solution known as "Half-mirror with built-in TV" is known, Korean Patent No. KR1020220011498 dated July 21, 2020. The invention describes a design in which a monitor, audio unit, and power, brightness, and sound control units are located behind a translucent mirror. It also claims to provide moisture protection and the ability to view television images through the mirror in a domestic setting. The emphasis is on the functional integration of the TV and mirror to improve consumer convenience in everyday life, without detailed thermal engineering or service access to components from the rear. The solution describes the combined operation of the mirror and display with basic control scenarios and moisture protection, but does not disclose the engineering details of the multilayer optics with an intra-package mirror layer or the design of passive heat dissipation through the glass and the fan-less housing.

[0006] The closest analog is the "Mirror Monitor," patent for utility model No. RU136267 dated June 3, 2013. The utility model features a mirror in front of a flat screen with a light-absorbing backing on the rear side and a connector panel in the frame. An IR receiver for controlling the TV is located on the rear side of the glass. Backlighting and time display options are provided, as well as mounting hardware for integration into furniture and openings. The utility model describes the mirror-TV arrangement with convenient access to connectors and additional lighting. However, it does not disclose the intra-package arrangement of the triplex mirror layer, the fanless passive thermal technology through the glass and housing, or the regulated service access through a removable rear cover.

[0007] The disadvantages of known solutions are:

[0008] - absence of an open passive heat dissipation system without fans with heat paths from the panel to the glass unit and / or to the body through thermal interfaces;

[0009] - absence of disclosure of the intra-package mirror coating in the triplex with protection from moisture and mechanical wear;

[0010] - lack of unified service access through the removable rear cover while the “body + glass unit” unit remains unchanged;

[0011] - lack of integration with smart home systems via the rear duplicate IR sensor connected to the front receiver;

[0012] - the absence of a solid rigid structure "body + glass" made of metal with high thermal conductivity, optimized for heat dissipation, moisture protection and installation.

[0013] Technical result

[0014] The technical result of the proposed invention is to increase reliability and durability at high brightness of display on a mirror surface, improve maintainability and integration with automation systems in conditions of limited ventilation and / or high humidity.

[0015] The technical result provides:

[0018] Passive heat paths from the panel to the glass and to the case through thermal interface elements with convective heat dissipation into the environment without the use of fans;

[0019] removable rear cover for service access to the panel and electronic components;

[0020] A duplicate infrared sensor on the back of the housing, electrically connected to the receiver on the front side for integration with smart home systems.

[0021] The technical result is achieved due to the fact that the mirror with a built-in TV contains a housing, a video display panel placed in the housing, and a translucent mirror glass installed in front of it, while:

[0022] The translucent glass is made in the form of multilayer glass with a mirror multilayer coating located between the glass layers, applied by vacuum magnetron sputtering;

[0023] The body is made of metal with high thermal conductivity and forms a rigidly fixed mounting structure with the specified glass;

[0024] Passive heat paths are provided from the panel to the glass and / or to the housing through thermal interface elements with subsequent convection into the environment without the use of fans;

[0025] The case is equipped with a removable rear cover for service access to the panel and electronic components;

[0026] There is a duplicate infrared sensor located on the back of the housing and electrically connected to the receiver on the front side for integration with smart home systems.

[0027] In addition, the mirror coating includes at least one metal layer and one dielectric layer.

[0028] In addition, the metal is selected from the group: titanium, aluminum, their alloys.

[0029] In addition, there is a thermal interface based on elastomer material between the panel and the glass.

[0030] In addition, there is a thermal interface in the form of a pad / gasket between the panel and the case.

[0031] In addition, the case is made with integral heat dissipation fins / pads.

[0032] In addition, the back cover is equipped with a seal around the perimeter and a sealed cable entry.

[0033] In addition, the smart home system controls the device via IR codes through the backup sensor.

[0034] In addition, the video display panel has increased brightness for display through mirror glass.

[0040] Detailed description of the invention

[0041] Design

[0042] Housing 1 is made of a metal with high thermal conductivity and integrated passive heat dissipation zones. It contains mounting shelves and attachment points for laminated glass 7 and matrix 2. Laminated glass 7 comprises at least two glass layers with a protective glass layer 10, between which a mirror coating 4 is located, formed by vacuum magnetron sputtering and protected within the package. Laminated glass 7 is sealed around the perimeter and secured within housing 1, forming a rigid mounting structure.

[0043] Display

[0044] The translucent mirror optics are provided by a 7-layer glass with a 4-layer mirror coating inside the package. This allows the device to function as a mirror when the 2-layer matrix is ​​turned off, and when turned on, it provides a display through the translucent structure. The optical structure of the 4-layer mirror coating balances reflection and transmission, and the increased brightness of the 2-layer matrix ensures image readability through the 7-layer glass. Coating 4: 70-80% reflection, 20-30% transmission, resulting in a total brightness of 800-950 nits.

[0045] Passive thermal engineering

[0046] Passive heat paths provide heat dissipation from matrix 2 to laminated glass 7 and parallel to case 1 through heatsink 8 with passive cooling 9. Heat dissipation is achieved through natural convection near the outer surfaces of laminated glass 7 and case 1. The design does not use fans, which reduces noise levels, improves fault tolerance, and prevents the suction of moist air into case 1 under limited ventilation conditions. With matrix 2 power up to 100 W (brightness 1000 nits), case 1 temperature is ≤50°C, matrix ≤60°C (margin +25°C).

[0047] Electronics and Integration

[0048] The electronic components housed within case 1 are the power supply 5 and motherboard 6, electrically connected to matrix 2. Vibration-pulse acoustics 3 provide audio. For interaction with smart home systems, a duplicate IR control module is located on the rear of case 1. It is electrically connected to the front command receiver, enabling the reception of IR codes both from the room and when mounted flush.

[0049] Installation and maintenance

[0050] The rigid "body 1 + laminated glass 7" design simplifies installation in recesses and on flat surfaces. Service access to the display 2, power supply 5, and motherboard 6 is provided through the rear cover without removing the laminated glass 7, reducing the risk of damage to the optics and reducing maintenance time.

[0051] Variants of the proposed invention may include various diagonals and form factors; various mirror coating compositions 4 for changing spectral properties; various designs with different levels of moisture protection for damp rooms.

[0052] Examples

[0053] Dry room version

[0054] In one embodiment, the device comprises a housing 1 made of a heat-conducting metal with integrated passive heat-dissipation zones and mounting shelves for multilayer glass 7, which ensures a rigid assembly and efficient heat transfer from the matrix 2 to the housing 1 without the use of fans; heat is dissipated by natural convection near the surfaces of the housing 1 and the multilayer glass 7. The multilayer glass 7 is designed as follows: a mirror coating 4 formed by vacuum magnetron sputtering is located between the glass layers, due to which the reflective layer is protected inside the package and is stable during operation and cleaning. The matrix 2 is mounted on the internal supports of the housing 1; a thermal interface is located between the matrix 2 and the multilayer glass 7, forming a heat path to the glass, and a radiator 8 with passive cooling 9 is located between the matrix 2 and the housing 1, forming a parallel heat path to the housing.The electronic components (power supply 5, motherboard 6) are accessible through the rear removable cover, allowing the device to be serviced without removing the laminated glass 7. For integration with smart home systems, a duplicate IR module is located on the rear side of the housing 1 and is electrically connected to the front command receiver.

[0055] Wet room version

[0056] In another embodiment, case 1 and laminated glass 7 form a rigid assembly with a reinforced sealing contour, designed for installation in rooms with high humidity without reducing the effectiveness of passive heat dissipation. The intra-package arrangement of mirror coating 4 prevents contact of the reflective layers with a humid environment and detergents. The configuration of heatsink 8 and passive cooling 9 is selected to maintain reliable thermal contact during temperature cycles and possible condensation; the heat paths operate completely passively with natural convection near the surfaces of laminated glass 7 and case 1; there are no fans, which prevents the suction of moist air into the case. Service access to the components is provided through the cover without removing laminated glass 7. A backup IR module provides control through construction niches and furniture panels.

[0057] Thus, the proposed invention provides increased reliability and durability with high display brightness on a mirror surface, improved maintainability and integration with automation systems in conditions of limited ventilation and / or high humidity.
