Abstract: A package includes a frontside redistribution layer (RDL) structure, a semiconductor die on the frontside RDL structure, and a backside RDL structure on the semiconductor die including a first RDL, and a backside connector extending from a distal side of the first RDL and including a tapered portion having a width that decreases in a direction away from the first RDL, wherein the tapered portion includes a contact surface at an end of the tapered portion. A method of forming the package may include forming the backside redistribution layer (RDL) structure, attaching a semiconductor die to the backside RDL structure, forming an encapsulation layer around the semiconductor die on the backside RDL structure, and forming a frontside RDL structure on the semiconductor die and the encapsulation layer.

Abstract: A multimedia device generates and outputs video signals to a display component and an external display device, and includes a video output circuit and a load detection circuit. The load detection circuit isolates and buffers the video output circuit and the load detection circuit, and retrieves horizontal sync signals from the video signals. The load detection circuit further amplifies and integrates the retrieved horizontal sync signals to output direct current signals, and finally compares the direct current signals with a predetermined voltage to output a control signal indicating a connection between the video output circuit and the external display device. The multimedia device turns off the display component according to the control signal indicating that the video output circuit has been connected to the external display device.
