  • Publication number: 20230320632
    Abstract: A display device comprising a display panel including a first non-folding area having a first emission area, a second non-folding area having a sensing area and a folding area that is disposed between the first non-folding area and the second non-folding area. A first light emitting diode is disposed in the first emission area and a second light emitting diode and a light receiving element are disposed in the sensing area. A processor obtains a biometric signal of a user by using the light receiving element and at least one of the first light emitting diode and the second light emitting diode. The processor generates biometric information based on the biometric signal. The processor detects the biometric signal when the display panel is folded so that the first non-folding area and the second non-folding areas are disposed to face each other.

  • Publication number: 20230156943
    Abstract: A display device includes: a first case and a second case connected to each other by a folding member; and a display panel that is at least partially disposed on a first surface of the first case, wherein a second surface of the first case is opposite to the first surface of the first case, wherein a third surface of the second case faces the second surface of the first case when the display device is in a folded state, and the third surface of the second case is coplanar with the second surface of the first case when the display device is in an unfolded state, wherein a first end portion of the display panel is fixed to the second case, and a position of a second end portion of the display panel is configured to change on the first surface of the first case.

  • Patent number: 10338124
    Abstract: Disclosed herein is a cable fault diagnosis system and method, wherein when an application signal and a reflected signal overlap each other due to the proximity of a fault location to an application location or when the intensity of the reflected signal is weak and thus falls outside of a prescribed fault diagnosis range due to remoteness of the fault location from the application location, a correction location, at which a correlation function value has a global maximum, is derived on the basis of a prescribed correlation function for an application signal applied to a cable to be inspected and an acquired reflected signal, a correction signal, which is a reflected signal from which the application signal is removed at the derived correction location, is calculated, the distance between the correction location and the acquisition location is derived on the basis of a time delay, which is calculated on the basis of the calculated correction signal and the reflected signal at the acquisition location, and a pr
