摘要： A light-emitting-diode (LED) driving circuit and a display device include a current driving circuit, a level detector, a comparing circuit, a digital control circuit, and a power supply circuit. The level detector detects a minimum detection voltage signal having a minimum voltage level among voltage signals of first terminals of respective LED strings. The comparing circuit generates a first comparison output signal and a second comparison output signal based on a headroom-control reference voltage and the minimum detection voltage signal. The digital control circuit adjusts a duty ratio of a gate control signal in a digital mode based on the first comparison output signal, the second comparison output signal and a control clock signal. Therefore, the LED driving circuit has a small area in a semiconductor integrated circuit.

摘要： Disclosed is a semiconductor silicon wafer having an electric power supply affixed to the backside of the wafer. By fabricating the electric power supply onto the backside of the wafer that has been left unused, the semiconductor chip can have a self-supplied power, realizing the self-powered semiconductor chip with an increased efficiency. Further, since the electric power supply is installed on the wafer, not the semiconductor chip, the fabrication procedure becomes very simple, and the battery can be mounted on any type of chip.
