  • Patent number: 12205738
    Abstract: A method of producing a sintered magnet is disclosed herein. In some embodiments, a method of producing a sintered magnet comprises, sintering a R—Fe—B based magnetic powder to produce a sintered magnet; wherein the R is Nd, Pr, Dy, Ce or Tb, and infiltrating a eutectic alloy into the sintered magnet, wherein the eutectic alloy contains Pr, Al, Cu and Ga, and wherein infiltration the eutectic alloy includes applying the eutectic alloy to the sintered magnet and heat-treating the sintered magnet to which the eutectic alloy is applied.

  • Publication number: 20250022420
    Abstract: A display device includes a display panel including first pixels arranged in a first row and second pixels arranged in a second row. A viewing angle of the first pixels is different from a viewing angle of the second pixels. The first pixels and the second pixels are disposed in a privacy region of the display panel and a public region of the display panel which is different from the privacy region. The display device further includes a panel driver configured to receive privacy region position information indicating a position of the privacy region, and drive the display panel such that the first pixels emit light in the privacy region of the display panel and the second pixels emit light in the public region of the display panel.
