According to various embodiments of the present disclosure, an electronic device includes: a housing; a touch circuit including a plurality of TX electrodes, and a plurality of RX electrodes arranged to cross over the plurality of TX electrode; a flexible display which includes the touch circuit, and which can be withdrawn from the inner space of the housing; a touch controller; and a processor operatively connected to the touch circuit, the flexible display and the touch controller, wherein the touch controller applies a driving signal by using the plurality of TX electrodes of the touch circuit, acquires the driving signal by using the plurality of RX electrodes, confirms a capacitance value on the basis of the acquired driving signal, and confirms information about a folded area of the flexible display on the basis of the capacitance value, and the processor can set an activation area for an unfolded area of the flexible display on the basis of the folded area of the flexible display. Various embodiments, in addition to various embodiments disclosed in the present document, are also possible.

Electronic device including flexible display, and display method using same

An electronic device may include a first structure, a second structure, a flexible display, at least one sensor, and at least one processor, wherein the at least one processor may be configured to: obtain information on a state of the first structure with respect to the second structure via the at least one sensor; detect a touch input via the at least one sensor; based on the information on the state of the first structure with respect to the second structure, identify a portion of the flexible display where the touch input is detected between a first portion visually exposed to an outside and a second portion accommodated in an inside of the second structure in the flexible display; and based on the identified portion being the second portion, perform a function associated with a screen displayed via the first portion, based on the touch input.

Electronic device comprising flexible display and operation method thereof

Various embodiments of the disclosure relate generally to an electronic device and its operating method for creating a calibration condition of an in-display fingerprint sensor and calibrating the fingerprint sensor according to the created condition, using a touchscreen display. The electronic device may according to various embodiments of the disclosure include a housing, a touchscreen display disposed inside the housing and viewable through one surface of the housing, an ultrasonic fingerprint sensor disposed inside the housing an overlapping one area of the touchscreen display when viewed from above the one surface of the housing, the ultrasonic fingerprint sensor further comprising a temperature measuring sensor, at least one processor operatively coupled with the touchscreen display and the ultrasonic fingerprint sensor, and at least one memory operatively coupled with the at least one processor, and configured to store a first reference fingerprint image relating to authentication using the ultrasonic fingerprint sensor, wherein the at least one memory may be configured to store instructions that, when executed, cause the at least one processor to control the electronic device to: measure a temperature change using the temperature measuring sensor, determine a presence of a foreign substance on the one area using the touchscreen display, and determine whether to calibrate the ultrasonic fingerprint sensor according to the temperature change, based at least in part on determining the presence of a foreign substance.
