Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A fan impeller includes a wheel casing, a plurality of fan blades and a plurality of first wind-guiding structures. The wheel casing is configured to rotate about an axis. The fan blades surround the axis and are arranged in a radial form. Each of the fan blades includes an end edge and two extending edges. The end edge is away from the wheel casing. The extending edges connect between the end edge and the wheel casing. The end edge and the extending edges define a windward surface and a leeward surface opposite to each other. The first wind-guiding structures are respectively disposed on the leeward surface of the corresponding fan blade. Each of the first wind-guiding structures is at least partially adjacent with the end edge and one of the extending edges of the corresponding fan blade.

Abstract: A touch panel including a substrate, first electrodes, second electrodes, first wires, second wires and a means for shortening a gap between the second electrodes in a third direction is provided. The first electrodes are arranged sequentially in a first direction. Each first electrode has openings arranged in a second direction intersecting the first direction. The second electrodes are located in the openings. Each first electrode and the second electrodes surrounded by the first electrode constitute a sensing unit. The first wires and the second wires connect the first electrodes and the second electrodes to a driving circuit. The means for shortening the gap between the second electrodes in the third direction renders a ratio of the gap between the second electrodes in the third direction to that in the second direction to be smaller than 1:3.4, where the third direction intersects either the first direction or the second direction.

Abstract: A touch panel, having a center region and a peripheral region disposed on at least one side of the center region, includes a first electrode. The first electrode includes a plurality of first sub-electrodes and a plurality of second sub-electrode. The first sub-electrodes are disposed in the center region, and the second sub-electrodes are disposed on the peripheral region. A pattern density of the second sub-electrodes in the peripheral region is higher than a pattern density of the first sub-electrodes in the center region.
