Abstract: A display apparatus including a substrate, a first sub-pixel, a second sub-pixel, and a third sub-pixel disposed on the substrate and configured to emit red light, green light, and blue light, respectively, partition walls disposed between the first sub-pixel, the second sub-pixel, and the third sub-pixel, and configured to not transmit light, in which the first sub-pixel, the second sub-pixel, and the third sub-pixel include a first light emitting cell, a second light emitting cell, and a third light emitting cell, respectively, and a height of each of the first, second, and third light emitting cells is lower than a height of the partition walls, and a difference between the height of the partition walls and the height of each of the first, second, and third light emitting cells is less than 100 ?m.

Abstract: A method for displaying battery information of an electronic device is provided. The method includes obtaining an operating history about one or more operations performed by the electronic device; determining a power usage about each of the one or more operations, based on the operating history; and determining an available time period for which a battery supplying power to the electronic device is capable to supply power to the electronic device, based on the power usage and a remaining capacity of the battery.

Abstract: A method and device for searching for a network in a wireless communication environment that supports a plurality of communication methods are provided. The method of searching for a network performed by an electronic device includes determining a battery level of the electronic device; searching for a first frequency band, when it is determined that the battery level is greater than or equal to a threshold value; and searching for a second frequency band, when it is determined that the battery level is less than the threshold value. The first frequency band includes an entire frequency band corresponding to a network which the electronic device supports, and the second frequency band includes a frequency band other than at least one frequency band included in the first frequency band.
