Abstract: A semiconductor structure includes a functional die, a dummy die, a redistribution structure, a seal ring and an alignment mark. The dummy die is electrically isolated from the functional die. The redistribution structure is disposed over and electrically connected to the functional die. The seal ring is disposed over the dummy die. The alignment mark is between the seal ring and the redistribution structure, wherein the alignment mark is electrically isolated from the dummy die, the redistribution structure and the seal ring. The insulating layer encapsulates the functional die and the dummy die.

Abstract: The present invention provides a display device, including: a first chromatic light source configured to generate first chromatic light, a dichroic reflection layer disposed on a light emergent side of the first chromatic light source and allowing the first chromatic light to pass through, and a quantum dot layer. The dichroic reflection layer has a first surface facing away from the first chromatic light source, and the first surface has a plurality of recessed portions. The quantum dot layer includes a plurality of quantum dot blocks, and the quantum dot blocks are disposed corresponding to the recessed portions.

Abstract: A display device is provided. The display device includes a self-emissive layer and a color filter layer. The self-emissive layer includes a plurality of self-emissive units and a plurality of first non-visible light generating units which is respectively disposed among the self-emissive units. The color filter layer is disposed on the self-emissive layer, and includes a shading matrix. The first non-visible light generating units and the shading matrix respectively have a first projection area and a second projection area on a projection plane parallel to the color filter layer. The first projection area and the second projection area at least partially overlap, and the shading matrix at least partially permits the passing through of the first non-visible light generated by the first non-visible light generating units.

Abstract: A display switch method for a portable device and an electronic device which are coupled to each other. In the method, when the portable device is coupled to the electronic device, the portable device stores a current operation status of the portable device according to a display switching signal. According to the hardware parameters of the display of the electronic device, the portable device adjusts a display setting. According to the stored operation status and the display setting, a first operation frame displayed on the portable device is changed to be a second operation frame displayed by a display of the electronic device.
