摘要： A portable communication device is provided. The communication device includes a first communication circuitry configured to perform communication using a first frequency band, a second communication circuitry configured to perform communication using a second frequency band, and at least one processor configured to receive a reference signal transmitted from a first external electronic device using the first communication circuitry, and when a received power corresponding to the reference signal belongs to a specified first range, communicate with at least one external electronic device through multiple cellular connections by transmitting a first signal of the first frequency band to the first external electronic device through a first cellular connection established using the first communication circuitry and substantially concurrently transmitting a second signal of the second frequency band to a second external electronic device through a second cellular connection established using the second communication circuitry.

摘要： A foldable electronic device includes: a display panel including a pixel array, a first region, a second region, and a folding region interposed between the first region and the second region, a plurality of gate lines connected with respective gates of a plurality of transistors included in the pixel array and extending in a first direction, a plurality of data lines connected with respective sources of the plurality of transistors and extending in a second direction crossing the first direction, a gate driving circuit connected with the plurality of gate lines, a display driver integrated circuit (DDI) connected with the plurality of data lines, a first detection line connecting a first gate line of the plurality of gate lines corresponding to the folding region with the DDI, a processor, and a memory operatively connected with the processor. The foldable electronic device is configured to be folded as the folding region is bent such that the first region corresponds to the second region, the DDI is configured to detect a first gate driving voltage applied to the first gate line by the gate driving circuit using the first detection line, and to transmit, to the processor, defect information indicating that the folding region is defective based on the first gate driving voltage being less than a reference voltage, and the memory stores instructions which when executed, cause the processor to: receive the defect information from the DDI, identify at least a portion of the folding region and/or the second region, based on the defect information as a defective region, and control the display panel to display an execution screen on the first region based on the identified defective region.
