Abstract: A modulation device including a plurality of electronic elements, at least one first signal line and a first driving circuit is provided. The at least one first signal line is respectively electrically connected to at least one of the electronic elements. The first driving circuit is electrically connected to the at least one first signal line. The first driving circuit provides a first signal to at least one of the at least one first signal line. The first signal includes a first pulse. The first pulse includes a first section and a second section closely adjacent to the first section.

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 urine testing strip and a urine testing system are provided. The urine testing system includes the urine test strip and a detection device. The urine test strip includes a working electrode, a counter electrode, a reference electrode, a trigger circuit and a protection layer. The protection layer covers the working electrode, the counter electrode and the reference electrode, and portions of the working electrode, the counter electrode and the reference electrode are exposed through an opening of the protection layer. The detection device includes a test strip receiving module and a wireless transmission module. The test strip receiving module is used to receive the test strip and to provide electric power to the test strip for obtaining a detection result. The wireless transmission module is used to transmit the detection result to a mobile computer device.
