Abstract: A light-emitting device is provided. The light-emitting device includes a light-emitting unit and a light-conversion structure disposed on the light-emitting unit, wherein the light-conversion structure includes a quantum dot layer and an etching blocking layer disposed on one of the surfaces of the quantum dot layer.

Abstract: A device includes an integrated circuit die attached to a substrate; a lid attached to the integrated circuit die; a sealant on the lid; a spacer structure attached to the substrate adjacent the integrated circuit die; and a cooling cover attached to the spacer structure, wherein the cooling cover extends over the lid, wherein the cooling cover attached to the lid by the sealant. In an embodiment, the device includes a ring structure on the substrate, wherein the ring structure is between the spacer structure and the integrated circuit die.

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: A display panel and a pixel circuit thereof are provided. The pixel circuit includes a driving current generator, a pulse width signal generator, a voltage provider, and a current enabler. The driving current generator provides a driving current. The pulse width signal generator includes an output switch. The output switch is controlled by a control signal, and provides a pulse width signal according to the control signal. The voltage provider adjusts the control signal according to a data write-in signal and a pulse width modulation enable signal. The current enabler provides the driving current to a lighting component according to the pulse width signal and an amplitude modulation enable signal.

Abstract: A method of applying heat to living tissue mainly uses a device for performing heat treatment on at least a portion of the living tissue in high-low-high temperature steps. In high temperature step, the temperature of the at least a portion of the living tissue is heated and kept between 39-46° C., and the heating period is no longer than 30 minutes. In low temperature step, the at least a portion of the living tissue is cooled, and the low temperature period should not be greater than a natural cooling time interval. In addition, the low temperature period must also be shorter than the heating period. Thus, the present invention allows the abnormal cells to be selectively restored or apoptotic without damaging the normal cells.
