Abstract: The disclosure provides a power management method. The power management method is applicable to an electronic device. The electronic device is electrically coupled to an adapter, and includes a system and a battery. The adapter has a feed power. The battery has a discharge power. The power management method of the disclosure includes: reading a power value of the battery; determining a state of the system; and discharging power to the system, when the system is in a power-on state and the power value is greater than a charging stopping value, by using the battery, and controlling, according to the discharge power and the feed power, the adapter to selectively supply power to the system. The disclosure further provides an electronic device using the power management method.

Abstract: An optoelectronic device includes a first semiconductor layer, a second semiconductor layer and an active layer between the first semiconductor layer and the second semiconductor layer; a first insulating layer on the second semiconductor layer and including a plurality of first openings exposing the first semiconductor layer, wherein the first openings include a first group and a second group; a third electrode on the first insulating layer and including a first extended portion and a second extended portion, wherein the first extended portion and the second extended portion are respectively electrically connected to the first semiconductor layer through the first group of the first openings and the second group of the first openings, and wherein the number of the first group of the first openings is different from the number of the second group of the first openings; and a plurality of fourth electrodes on the second insulating layer and electrically connected to the second semiconductor layer, wherein in a
