Resumen de: US2025158560A1
Photovoltaic roof tiles are provided with interlocking edges; however, these can be expensive to manufacture and time-consuming to install. A more cost-effective option of tiling may use a double-lap tile arrangement. Because plain tiles have no interlocking edges, water can leak through the joins between tiles. This requires a third tile to be placed below the join to catch any water passing through. With double-lap tiles, a significant part of each tile remains covered after installation, such that a relatively small surface area is in view of the sun. Photovoltaic roof tile 302 is useable with double-lap tiles 301, the photovoltaic roof tile 302 having a tile width equal to an integral multiple of the double-lap tile width. In this way, such photovoltaic roof tiles 302 may be arranged with conventional double-lap roof tiles 301 to increase the proportion thereof available to sunlight 305, 307, without risking ingress of water.

Known photovoltaic roof tiles replace traditional roof tiles in a single lap arrangement. In order to prevent rainwater from passing between adjacent tiles and permeating into a building below, the photovoltaic roof tile is provided with interlocking edges; however, the manufacturing cost of these devices may be very high, and the installation is also time-consuming. One more economical choice of laying tiles is the use of a double lap tile arrangement. Because the planar tiles have no interlocking edges, water may leak through the joints between the tiles. This entails the placement of a third tile under the joint to intercept any passing water. However, when the double lap tiles are used, a substantial portion of each tile is still covered after installation, so that a relatively small surface area can be exposed to the sun. This is not effective utilization of expensive photovoltaic materials. The invention provides a photovoltaic roof tile 302 for use with a double lap tile 301, the tile width of the photovoltaic roof tile 302 being equal to an integer multiple of the width of the double lap tile. In this manner, such a photovoltaic roof tile 302 can be arranged with a conventional double lap roof tile 301 to increase the proportion it can be used to receive sunlight 305, 307 without the risk of water ingress.

In one example, a method of manufacturing includes forming, by an additive manufacturing process, a stackup of half-panels comprising connected pairs of the half-panels each having an integrated construction comprising a webbing structure connected to a skin layer substantially covering a face. The method also includes separating the stackup into detached pairs of the half-panels, assembling a selected detached pair of the half-panels into a full panel, and attaching photovoltaic cells to a selected face of the full panel.

Provided is a display device including a display panel including a display region and a non-display region, and an input sensing device disposed on the display panel. The input sensing device includes a first sensing insulation layer directly disposed on the display panel, a first sensing conductive layer disposed on the first sensing insulation layer, a second sensing insulation layer disposed on the first sensing insulation layer and covering the first sensing conductive layer, and a second sensing conductive layer disposed on the second sensing insulation layer. The second sensing insulation layer includes an organic film, and a first thickness of the first sensing conductive layer is greater than a second thickness of the second sensing conductive layer.
