In the present disclosure, an area in which the processor displays the user interface among the areas of the flexible display may be referred to as a logical display, and as the structure of the flexible display is changed, an area in which the user interface can be displayed in the current state may be referred to as a physical display.

3 and 4 are diagrams illustrating a logical display divided into an ideal case and a realistic case as the physical display expands according to various embodiments.

When the electronic device 410 displays the user interface by determining the size of the logical display as the size of the physical display derived using the sensor measurement value, only a part of the user interface may be displayed on the part of the actual physical display.

5 is a flowchart of correcting an error value of a sensor measurement value according to various embodiments of the present disclosure;

According to an embodiment, in operation 510 , the electronic device (eg, the electronic device 101 of FIG. 1 ) uses a sensor module (eg, the sensor module 176 of FIG. 1 ) to an externally displayed display (eg, FIG. 1 ). The screen length of the first position of the display module 160 of 1 may be measured. The length of the display measured in operation 510 to distinguish it from the length of the display measured below may be referred to as a first position screen length.

In operation 520 , the electronic device 101 may measure the changed length of the display 160 . For example, when a change in the length of the display 160 is detected, the electronic device 101 may measure the length of the screen at the second position of the display 160 . The length of the display measured in operation 520 may be referred to as a second location screen length to distinguish it from the length of the display measured in operation 510 . As another example, the electronic device 101 may measure the length of the display 160 that is periodically viewed to the outside after a predetermined time has elapsed.

In operation 530 , the electronic device 101 may determine whether the screen length of the second position of the display 160 measured in operation 520 is greater than a threshold value than the length of the screen of the first position of the display 160 measured in operation 510 . . Operation 530 may be an operation in which the electronic device 101 determines whether to update the logical display.

If the length of the screen at the second position of the display 160 measured in operation 520 is greater than the minimum threshold than the length of the screen at the first position of the display 160 measured in operation 510, the electronic device 101 determines the display area in operation 540 For this purpose, sensor measurements can be passed to the process to determine the size of the logical display. The electronic device 101 may correct the sensing error value based on the screen length of the second position of the display 160 measured in operation 520 . The electronic device 101 may correct a sensing error value using a look-up table. According to various embodiments, operation 540 may be processed by a module for processing display information in the processor, for example, a display extension manager of a framework layer.

If the screen length of the second position of the display 160 measured in operation 520 is less than the minimum threshold, the electronic device 101 may perform operation 520 again if the length of the screen at the first position of the display 160 measured in operation 510 is less than the minimum threshold. there is.

In operation 550 , the electronic device 101 may determine whether the movement of the display 160 has been completed. For example, if the movement of the display 160 is within a predetermined range for a predetermined time, the electronic device 101 may determine that the sliding has been completed.

When it is determined that the movement of the display 160 is completed, the electronic device 101 may end measuring the length of the display 160 in operation 560 .

If it is determined that the movement of the display 160 is not completed, the electronic device 101 may change the length of the screen at the second location to the length of the screen at the first location in operation 555 and perform operation 520 again.

According to an embodiment, the amount of change in movement of the display at time n may be expressed as follows.

dX _n = X _n - X _n-1

Here, X _n represents the length of the display at time n, and X _n-1 represents the length of the display at time n-1. If dX _n is greater than 0, it may indicate movement in a consistent direction based on the current position, and if dX _n is less than 0, it may indicate movement by changing the direction in the opposite direction with respect to the current position. The moving direction of the display may be one-dimensional or two-dimensional.

According to an embodiment, the electronic device may differently process a display sliding event according to a threshold value.

The minimum threshold (X _th,min ) may be a reference value that does not need to update the logical display because the length of the display 160 is slightly changed. The minimum threshold value may be a reference value determined as an error value of a sensor measurement value. The maximum threshold (X _th,max ) has a value smaller than the area of the entire display and may be a reference value that prevents abrupt changes in the logical display due to a large shift from the current position or an error in an excessively large sensor measurement value. The maximum threshold value may be changed in real time by estimating the movement direction through the amount of movement change of the display and using this. The minimum and maximum thresholds may be determined by at least one of a sensor type, a sensor method, a sensor sensitivity, a sensor specification, a display size, a battery capacity, a user setting, an experimental result, and a resolution.

For example, if the display is physically continuously expanded and extended by pixels, the initially set maximum threshold is 8 pixels. can be increased to 16 pixels in a doubling. As another example, when the display is physically continuously reduced, the maximum threshold value may decrease from 16 pixels to 8 pixels when the amount of change in movement of the display is smaller than a predetermined value. The minimum threshold may also increase or decrease similarly to the maximum threshold. Here, it is expressed as a movement change amount, but the movement speed can be compared with a constant value.
