  • Patent number: 10910584
    Abstract: A light emitting device includes a substrate. A thin film transistor is disposed on the substrate. A first electrode is connected to the thin film transistor. A second electrode at least partially overlaps the first electrode. A first partition wall is disposed between the first electrode and the second electrode. An insulating layer is disposed between the thin film transistor and the first electrode. The insulating layer includes a first part having a first thickness and a second part having a second thickness that is different than the first thickness. The second part of the insulating layer at least partially overlaps the first partition wall.

  • Patent number: 10811641
    Abstract: A display device includes: a substrate on which is disposed: an organic light emitting element which generates and emits light with which an image is displayed; a thin film transistor connected to the organic light emitting element and with which the organic light emitting element is controlled to emit the light; an interlayer insulating layer disposed between the thin film transistor and the organic light emitting element, the interlayer insulating layer including an organic material; and a capping layer disposed between the interlayer insulating layer and the organic light emitting element, the capping layer including an inorganic material. The interlayer insulating layer disposed between the thin film transistor and the organic light emitting element does not have photosensitivity and does not include sulfur.

  • Patent number: 10684383
    Abstract: Provided is an earthquake response system using a seismic motion sensor. The seismic motion sensor of the earthquake response system includes: a sensor unit measuring a sensor value including peak ground acceleration (PGA) of the ground due to shaking; a seismic motion sensing unit sensing seismic motion on the basis of a seismic motion sensing result value calculated from an artificial neural network that uses the peak ground acceleration as input when the peak ground acceleration satisfies a seismic motion sensing condition; a seismic motion determiner determining generation of final seismic motion on the basis of a seismic motion determination parameter calculated from the sensor value on the basis of the seismic motion sensing result; a shaking grade calculator calculating a shaking grade of the determined final seismic motion through the peak ground acceleration; and a communication unit notifying the shaking grade of the final seismic motion.
