Abstract: An electronic device includes a display, a rear cover, a side member surrounding the space between the display and the rear cover, the side member having a groove formed therein, a side key disposed the groove and including a conductive portion, a wireless communication circuit, at least one processor, and a first conductive connection member electrically connecting the at least one processor to the side key. The wireless communication circuit is configured to feed power to a first portion of the side member surrounding an edge of the groove through the first conductive connection member electrically connecting the at least one processor to the side key, and transmit and/or receive radio frequency (RF) signals in a specified frequency band, based on an electrical path formed in the first portion of the side member and the conductive portion of the side key.

Abstract: An electronic device is provided. The electronic device includes a housing having a front surface and a rear surface, a first antenna, a second antenna, a printed circuit board, and an electromagnetic interference (EMI) shielding sheet. The first antenna may be disposed inside the housing. The second antenna may be disposed in an area surrounded by a radiator of the first antenna when viewed from above the rear surface. The printed circuit board may include a wireless communication module for operating the first antenna and the second antenna, and may be electrically connected to the first antenna and the second antenna. The first antenna may be positioned between the rear surface and the EMI shielding sheet.

Abstract: A current-voltage (IV) relationship of a pixel having a diode is initially determined. A first voltage is determined that does not cause the diode to emit light, and a first current across the diode is sensed by applying the first voltage. A predetermined current is determined based on the first voltage and the IV relationship. A ratio is determined based on the first current, a target current, and the predetermined current. A ratio voltage is determined by applying the ratio to a predetermined target voltage. If the first current is less than the predetermined current, then the ratio voltage is applied to supply a target current to the diode. If the first current is greater than the predetermined current, then a second voltage is determined by averaging the first test voltage and the ratio voltage, and the second voltage is applied to supply the target current to the diode.

Abstract: Systems and methods are presently disclosed that compensate for temperature-based parasitic capacitance variation of a pixel of a display by causing a driver transistor of the pixel to enter an ohmic or linear region. A lookup table is generated based on temperatures at the pixel, diode voltages, and target diode currents or luminances at a diode of the pixel. A correction voltage is determined based on a target diode current or luminance, a temperature at the pixel, and the lookup table. A data voltage is applied corresponding to the target diode current or luminance and the correction voltage to the driver transistor.
