Abstract: A display device including a substrate including a display area and a non-display area, pixels provided in the display area, an encapsulation layer on the pixels, a first conductive pattern on the encapsulation layer and including a first metal layer of sensing lines disposed in a non-sensing area corresponding to the non-display area, a first insulating layer on the first conductive pattern, a second conductive pattern on the first insulating layer and including a second metal layer of the sensing lines, and a second insulating layer on the second conductive pattern, in which the first metal layer includes a first end located in the non-sensing area corresponding to a first side of a sensing area and a second end located in the non-sensing area corresponding to a second side adjacent to the first side, and the first end and the second end are spaced apart from each other.

Abstract: Disclosed are a device, a system, and a method of providing treatment information for a skin care treatment. The device includes: a patient information providing unit configured to provide patient information; a treatment information generating unit configured to generate treatment information based on the patient information; a progress information input unit configured to receive progress information for the treatment when the treatment is completed based on the treatment information; and a control unit configured to update the treatment information based on the progress information. Therefore, it is possible to provide the skin care treatment in a more objective state by preventing the treatment from being performed under different conditions for each practitioner or according to a condition of the practitioner, and it is further possible to perform a safe and effective treatment by preventing misuse of medical technology due to the misjudgment of the practitioner.
