A process for room temperature substrate bonding employs a first substrate substantially transparent to a laser wavelength is selected. A second substrate for mating at an interface with the first substrate is then selected. A transmissivity change at the interface is created and the first and second substrates are mated at the interface. The first substrate is then irradiated with a laser of the transparency wavelength substantially focused at the interface and a localized high temperature at the interface from energy supplied by the laser is created. The first and second substrates immediately adjacent the interface are softened with diffusion across the interface to fuse the substrates.

A cover glass element can extend to the edges of an electronic device while maintaining the optical flatness and thickness needed for the cover glass. A first glass sheet with the desired thickness and flatness can be thermally bonded to a second glass sheet machined to include an opening to be received by the edges of the electronic device. The resulting three-dimensional cover element forms a uni-body frame that is significantly stiffer than a single sheet of glass, and the larger surface area of the edge provides for enhances pressure distribution, particularly after chemical strengthening, thus enhancing the durability of the electronic device. Further, the thermal bonding process uses lower temperatures than processes such as slumping or pressing, which could potentially affect the flatness and optical clarity of the original sheet glass.

The present invention relates to a method for manufacturing a bended glass sheet with a permanent glass sheet bending. The method (cold bending of a glass sheet) comprises following steps : a) Providing a tempered flat precursor glass sheet with a glass sheet thickness selected from the range between 2 mm and 10 mm; b) bending the tempered flat precursor glass sheet with the aid of an external bending force such, that a bended glass sheet with a glass sheet bending results; and c) fixing the glass sheet bending of the bended glass sheet such, that the permanent glass sheet bending results; wherein the bending the tempered flat precursor glass sheet is executed at a bending temperature which is selected from the range between 0°C and 70°C. In a preferred embodiment the bending temperature is selected from the range between 0°C and 50°C and particularly from the range between 0°C and 40°C. Moreover a manufacturing system for executing the method with is provided. The use of the method relates to the manufacturing of a bended mirror with a permanent mirror bending. For instance, a tempered glass sheet is coated with a multilayer stack with a reflecting layer containing Silver. This coated glass sheet is brought into the desired parabolic shape by the described bending process. In view of a solar field application it is advantageous that instead of 2 or 3 mirrors one "long" mirror can be used. This reduces the costs and improves the optical performance. The bended mirror or the assembly with the bended mirror is used as a sunlight concentrator.

The invention discloses a method for making glass ceramic composite structures, wherein a first (16) and at least a second (18) glass component, with an intermediate layer of a joining solder (20) consisting of glass placed between them, are assembled to form a raw composite structure, where the joining solder (20) has a radiation absorption capacity higher than the components (16, 18) to be joined, and where the raw composite structure is irradiated with energy, for example IR energy, at least in the area of the joining solder (20) until the joining solder (20) has softened sufficiently to bond together the components (16, 18) and the joining solder (20) to produce a composite glassy structure. Thereafter a ceramization treatment is performed.
摘要:
A mask for laser sealing a temperature and environmentally sensitive element, such as an OLED device, surrounded by a frit wall between first and second substrates. The mask is opaque and has a transparent elongate transmission region. The width of the transmission region may be substantially equal to the width of the frit wall. A strip of opaque mask material extends approximately along a longitudinal center line of the elongate transmission region. The mask is located between a laser and the first or second substrate. The laser emits a generally circular beam having a diameter that is larger than the width of the frit wall and is directed through the transmission region in the mask, such that opaque portions of the mask block portions the laser beam and the transparent transmission region allows a portion of the laser beam to pass through the mask and impinge upon the frit wall to melt the frit wall, thereby joining the first and second substrates and hermetically sealing the element therebetween. A process and system for sealing such an element between a first substrate and a second substrate separated by at least one frit wall employing such mask.

Glass tesseras specially created for composing ornamental mosaics, characterised by the formal thickness of two flat elements made of industrial glass, which are superimposed and joined through thermic fusion and coloured during the process of fusion (or joining) of the same, with eliminating all risk of the two plates separating or coming unglued, something that could occur in a simple glued sandwich structure and with physical superficial effects of brilliance and/or refractivity, giving a visual effect of depth that cannot be found in products using the preceding technique.
