Abstract: A sweep voltage generator and a display panel are provided. The sweep voltage generator includes an output node, a current generating block and a voltage regulating block. The output node is used to provide a sweep signal. The current generating block is coupled to the output node, includes a detection path for detecting an output load variation on the output node, and adjusts the sweep signal provided by the output node based on the output load variation. The voltage regulating block is coupled to the output node for regulating a voltage of the output node.

Abstract: A semiconductor package includes a first die, a second die and a redistribution layer structure. The first die and the second die are disposed laterally. The redistribution layer structure is disposed over and electrically connected to the first die and the second die, wherein the redistribution layer structure includes a plurality of vias and a plurality of lines stacked alternately and electrically connected to each other and embedded by a plurality of polymer layers, and wherein from a top view, first vias of the plurality of vias overlapping with the first die or the second die have an elliptical-like shape.

Abstract: A portable electronic system is provided. The portable electronic system includes a wearable device and a host. The wearable device includes a connector and a magnetic-reed switch. The connector includes a first detection point. The host detects a voltage at the first detection point and a state of the magnetic-reed switch when the host performs a detection operation. The host performs at least one of a plurality of functional operations according to a detection result of the detection operation.

Abstract: An audio system of a tablet personal computer and the speaker orientating method thereof are provided, wherein the audio system comprises at least two speakers mounted on a frame of the tablet personal computer, an angle detector mounted on the frame, an audio driver used to drive the speakers, and an audio-adjusting device. The audio driver can adjust the sound field of each speaker in accordance with a set of audio parameters. The angle detector is used to generate positional data as the frame is rotated relative to the ground. The audio adjusting device is used to renew the audio setting in accordance with the positional data to make the speakers provide an audio stereophony substantially equal to the predetermined stereophony.
