  • Patent number: 12255267
    Abstract: A display device includes a first electrode and a second electrode disposed on a substrate and spaced apart from each other in a first direction. A light emitting element is disposed between the first electrode and the second electrode. A third electrode is disposed on the first electrode and electrically contacts an end portion of the light emitting element. A fourth electrode is disposed on the second electrode and electrically contacts another end portion of the light emitting element. A side of the third electrode and a side of the first electrode are located on a first virtual line substantially perpendicular to the substrate. A side of the fourth electrode facing the side of the third electrode and the side of the second electrode are located on a second virtual line substantially perpendicular to the substrate.

  • Patent number: 12218113
    Abstract: A display device includes a substrate, a data conductive layer on the substrate and including a first voltage line, a via layer on the data conductive layer, a light emitting element on the via layer, a first contact electrode on the light emitting element and contacting a first end of the light emitting element, and a second contact electrode on the light emitting element and contacting a second end of the light emitting element, wherein the second contact electrode is electrically connected to the first voltage line through a first contact hole penetrating the via layer.

  • Patent number: 12206396
    Abstract: Disclosed is a low-voltage detection floating N-well bias circuit. The circuit includes a power detector configured to detect states of first power (VDD) and second power (DVDD) at different power levels; a switch configured to perform a switching operation according to the states of the first power (VDD) and the second power (DVDD); and a voltage output circuit configured to output the first power (VDD) or the second power (DVDD) as an N-well bias voltage according to the states of the first power (VDD) and the second power (DVDD) and the switching operation of the switch. Accordingly, when the first power (VDD) and the second power (DVDD) are supplied and the second power (DVDD) has a low voltage state, the floating N-well bias circuit can continuously bias an N-well with the second power (DVDD), without dropping the second power (DVDD).

  • Publication number: 20220152439
    Abstract: The present invention relates to a fire extinguishing micro-capsule, a method for manufacturing the same, and a fire extinguisher using the same. The fire extinguishing micro-capsule has a core-shell structure in which a core includes a liquid fire extinguishing agent and a shell uses a high-density non-porous polymer material. A decapsulation process of the fire extinguishing micro-capsule occurs in a narrow time and temperature range at a rate of at least 150%/min, and the stability of the agent in water and other solvents is significantly increased. A fire extinguisher including the fire extinguishing micro-capsule has increased lifetime and operational efficiency.

  • Patent number: 10762242
    Abstract: A method and system for operating an electronic apparatus includes: implementing, by a first processor, a main process of the electronic apparatus; receiving a user input for controlling an operation of at least one element (e.g., camera, memory, microphone, or the like) configured to perform at least one function; and in response to a received user input, controlling power of the at least one element by using at least a second processor separate from the first processor.
