    Abstract: An electronic device and a method for driving a plurality of display areas of a display at different driving frequencies are provided. The electronic device can determine a first driving frequency of a first application, and the position of a first portion on which a first execution screen of the first application is to be displayed, determine a second driving frequency of a second application, and the position of a second portion on which a second execution screen of the second application is to be displayed, determine a third driving frequency of a third application, and the position of a third portion on which a third execution screen of the third application is to be displayed, and drive a first area of the display panel based on a first partial scan rate, and drive a second area of the display panel based on a second partial scan rate.

    Abstract: A method of cleaning a collector of an extreme ultraviolet light source system includes introducing the collector separated from the extreme ultraviolet light source system into a chamber; capturing an optical image of a reflective surface of the collector; measuring a contamination level of the reflective surface by comparing the optical image with a prestored standard image; performing a first cleaning operation if the contamination level exceeds a preset first reference value, the first cleaning operation including cleaning the reflective surface by spraying dry ice particles onto the reflective surface; and performing a second cleaning operation if the contamination level is less than or equal to the preset first reference value. The second cleaning operation includes cleaning the reflective surface by radiating atmospheric plasma onto the reflective surface and measuring a microcontamination level and a damage level of the reflective surface.

    Abstract: According to various exemplary embodiments, there may be provided an electronic device including a housing having a first area facing a first direction and a second area facing a second direction, wherein the housing includes a window formed on at least one portion of the first area, a display module disposed between the window and the second area, a light converting member disposed between the window and the second area and configured to transmit light emitted from the display module in the first direction by at least partially converting a wavelength of the light reflected in the second direction by an external object of the housing, and an optical sensor disposed between the light converting member and the second area, wherein the optical sensor is configured to detect the object by using the light of which the wavelength is converted. Other various exemplary embodiments are also possible.
