Abstract: Provided are a method of manufacturing a micro-LED and a method of manufacturing a display apparatus to which the method is applied. In the method of manufacturing a micro-LED, a membrane formed to include a cavity is formed on a substrate, and then, a sacrificial layer that may be selectively removed by wet etching is formed on the membrane. Next, a light-emitting device is formed on the sacrificial layer, and the light-emitting device is separated from the membrane by the wet etching. In an example, an undoped semiconductor layer may further be formed between the membrane and the sacrificial layer. The sacrificial layer may include an oxide layer having the same crystal lattice structure as that of the undoped semiconductor layer. In an example, another undoped semiconductor layer may further be formed between the sacrificial layer and the light-emitting device.

Abstract: Various embodiments of the disclosure relate to an apparatus and method for providing a call function in an electronic device. The electronic device includes first communication circuitry, second communication circuitry, and a processor. The processor registers with a network using NR communication through the first communication circuitry, identifies whether a call connection using a network using the wireless LAN communication is possible, based on determination that establishment of a communication link related to a call connection with an external electronic device using the network using the NR communication and/or a network using LTE communication fails, and connects a call with the external electronic device over the network using the wireless LAN communication, based on determination that the call connection using the network using the wireless LAN communication is possible. Other embodiments may be possible.
