Abstract: The present disclosure relates to a display panel and its repair method. The display panel may include: a first sub-pixel including a first-first light-emitting element and a first-second light-emitting element; a second sub-pixel including a second-first light-emitting element and a second-second light-emitting element; a first cathode line connected to at least one cathode electrode among a cathode electrode of the first-first light-emitting element and a cathode electrode of the first-second light emitting element, and extended toward the second sub-pixel; and a second cathode line connected to at least one cathode electrode among a cathode electrode of the second-first light-emitting element and a cathode electrode of the second-second light emitting element, and extended toward the first sub-pixel.

Abstract: A printed circuit board includes a glass layer, a through-hole penetrating through the glass layer, a seed layer provided along an inner wall of the through-hole, and a through-via disposed on the seed layer and filling the through-hole. The seed layer includes a carbon-based conductive material.

Abstract: An integrated fluid distributor includes a single case in which flow paths for different fluids are independently disposed. The integrated fluid distributor may also be capable of distributing and discharging respective fluids. The integrated fluid distributor includes a case, and a first flow path disposed within the case. The first flow path has a first inlet, a plurality of first outlets, and a plurality of first valves for a first fluid. The integrated fluid distributor also includes a second flow path disposed independently of the first flow path within the case. The second flow path has a second inlet, a plurality of second outlets, and a plurality of second valves for a second fluid.

Abstract: A sensor cleaning system includes: an air nozzle that sprays compressed air toward a sensor; a liquid nozzle that sprays liquid toward the sensor; a fluid tank that stores compressed air to be supplied to the air nozzle and liquid to be supplied to the liquid nozzle; an air compressor that compresses and supplies external air into the fluid tank; and a distributor that selectively supplies compressed air from the fluid tank to the air nozzle and selectively supplies liquid from the fluid tank to the liquid nozzle.

Abstract: An integrated cleaning module of a vehicle sensor includes a washing liquid supply module configured to supply cleaning liquid; and an air supply module connected to the washing liquid supply module and configured to supply air. The air supply module includes a compressor configured to generate compressed air; an air tank in which the compressed air generated by the compressor is stored; and an integrated dispenser configured to be in fluid connection with the washing liquid supply module and the air tank. The integrated dispenser is configured to distribute the cleaning liquid and the compressed air.

Abstract: This invention discloses a fabricating method of the Printed Circuit Board, comprising the steps of (a) laminating an RCF and a copper layer on the internal core via vacuum press; (b) performing a first curing process; (c) making via-holes and filling out the via-holes and coating the surface of the copper layer with copper plating; (d) preparing a mask layer having a window which exposes the surface of the RCF region for the definition of the cavity; (e) etching the RCF with the surface exposed either via the pumice process or via the wet blast process; and (f) removing the mask layer and performing a second curing process.
