The operation of detecting the slide movement of the second housing,
Including determining that the electronic device is in the second state or the third state based on receiving the light through the sensor module.
method. According to claim 15,
The operation of detecting the slide movement of the second housing,
and determining that the electronic device is in a third state based on sensing a first light output from the first dummy pixel through the sensor module.
method. 17. The method of claim 16,
The operation of detecting the slide movement of the second housing,
And determining that the electronic device is in a second state based on sensing a second light output from the second dummy pixel through the sensor module.
method. 18. The method of claim 17,
The operation of detecting the slide movement of the second housing,
An operation of determining the brightness of light received through the sensor module;
determining whether the received light is the first light output from the first dummy pixel or the second light output from the second dummy pixel, based on the determined brightness; and
Based on the determined result, determining whether the electronic device is in the second state or the third state,
method. 18. The method of claim 17,
The brightness of the first light output from the first dummy pixel is different from the brightness of the second light output from the second dummy pixel;
a diameter of a first hole of the bendable member disposed to overlap the first dummy pixel is equal to a diameter of a second hole of the bendable member disposed to overlap the second dummy pixel;
method. 18. The method of claim 17,
The brightness of the first light output from the first dummy pixel is equal to the brightness of the second light output from the second dummy pixel;
a diameter of a first hole of the bendable member disposed to overlap the first dummy pixel is different from a diameter of a second hole of the bendable member disposed to overlap the second dummy pixel;
