Abstract: A smoke detector with an anti-insect function includes a substrate, an optical detection module, a top cover, a base and a perforated plate. The substrate has a ring shape region surrounding a central detection region, and a first block structure of the central detection region is protruded from the substrate and higher than an upper surface of the ring shape region. The optical detection module is disposed inside the central detection region. The top cover has a lateral wall. The base is disposed on the substrate and connected to the top cover to cover the optical detection module. The base has a second block structure partly overlapped with the lateral wall to form a guiding channel. The perforated plate is disposed between the lateral wall and the second block structure to prevent an insect from moving into the top cover through the guiding channel.

Abstract: An image projector in a case, having a light engine, a circuit board, a heat sink assembly, and a fan assembly, has one or more heat sinks and heat pipes shaped to gather heat from all heat-generating components within the projector and a single air passage to receive the heated air combined from all components, allowing the employment of a single fan module in sucking cool air from the exterior and exhausting heated air through the single air passage.

Abstract: An organic electroluminescent display panel comprises a substrate, at least one organic light-emitting area, at least one protecting layer, at least one isolation layer and at least one protrusion. In this case, the organic light-emitting area comprises a plurality of pixels and is disposed over the substrate. The protecting layer is disposed over the substrate and the organic light-emitting area. The isolation layer is disposed over the protecting layer.
