  • Publication number: 20240138176
    Abstract: A display device includes first and second light emitting regions; first and second pixel electrodes in the first and second light emitting regions, respectively; a first organic layer in the first light emitting region, including first and second light emitting layers; a second organic layer in the second light emitting region, including a third light emitting layer; a common electrode on the first and second organic layers; a wavelength conversion pattern on the common electrode, overlapping the first organic layer, and wavelength-converting light of a first color into light of a second color, different from the first color; and a light transmitting pattern on the common electrode, overlapping the second organic layer. The third light emitting layer and one of the first and second light emitting layers emit light of the first color, and another one of the first and second light emitting layers emits light of the second color.

  • Patent number: 10161597
    Abstract: A lighting system and a selective retro-reflection apparatus are provided. The lighting system includes a lamp, a reflector configured to reflect light emitted by the lamp, a projection lens configured to emit the reflected light of the reflector in a predetermined direction, and a selective shield apparatus disposed between the projection lens and the reflector and provided on a path of light directed upward among the light reflected from the reflector to selectively shield the light directed upward, wherein the selective shield apparatus includes a panel and a selective shield portion supported by the panel, positions of the panel and the selective shield portion are fixed, and a state in which the selective shield portion transmits the light is changed according to whether power is supplied.

  • Patent number: 9151682
    Abstract: A sensor for measuring heat generated from cells, including a thermopile manufactured by surface-micromachining technology, and a microfluidic flow-channel structure for mixing cells with medium and dividing the mixture into cells and medium. Medium and cells are uniformly mixed using a micro-mixer. The mixture is separated into a medium microfluid and a cell microfluid using the Zweifach-Fung effect, after which signals measured in the two microfluids are amplified. The difference between the two signal values determines the amount of heat generated from the cells. The influence of noise caused by a change in external environment is eliminated. Convection heat dissipation caused by fluid flow is minimized. The sensor accurately measures the amount of heat generated from cells flowing in the microfluidic flow-channel. Diseases such as cancer are diagnosed using the difference between the measured amount of heat generated from cells and the standard amount of heat generated from normal cells.

  • Patent number: 9028450
    Abstract: Disclosed are a syringe capable of measuring an inner temperature of a patient body and a method of manufacturing the same. In the syringe, a different metal from that of a syringe needle is deposited on an inclined surface of a tip portion of the syringe needle to form a thermocouple junction with the metal of the syringe needle, whereby the region causing pain in a patient body can be diagnosed while allowing administration of medicine thereto, thereby enabling efficient treatment and significantly reducing potential harm due to drug abuse.
