Description

A cover member and an electronic device including the cover member Various embodiments of the present disclosure relate to a cover member and an electronic device comprising said cover member. Driven by remarkable advancements in information and communication technology and semiconductor technology, the distribution and use of various electronic devices are increasing rapidly. In particular, recent electronic devices are being developed to enable portable communication. The term "electronic device" refers to a device that performs specific functions according to an installed program, ranging from home appliances to electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, video/audio devices, desktop/laptop computers, and in-car navigation systems. For example, these electronic devices can output stored information as sound or video. As the integration density of electronic devices increases and ultra-high-speed, high-capacity wireless communication becomes commonplace, various functions can now be integrated into a single electronic device, such as a mobile communication terminal. For instance, not only communication functions but also entertainment functions like games, multimedia functions like music/video playback, communication and security functions like mobile banking, and functions such as schedule management and electronic wallets are being integrated into a single electronic device. These electronic devices are being miniaturized to allow users to carry them conveniently. Furthermore, in an information-based society, the importance of power supply to electronic devices is increasingly being highlighted to enable information and communication devices to connect and operate regardless of time or place. Wireless power transmission technology has recently been receiving attention for providing a simpler method of power supply to electronic devices and/or charging batteries included in electronic devices. For example, a wireless power receiving device, such as a mobile device that receives energy wirelessly, can be driven by the received wireless power, or can charge a battery using the received wireless power and be driven by the charged power. Wireless power transmission (or wireless energy transfer) is a technology that transmits electrical energy wirelessly from a transmitter to a receiver using the principle of magnetic field induction. Wireless energy transfer methods can be broadly classified into magnetic induction, electromagnetic resonance, and power transmission methods using short-wavelength radio frequencies.
