Publication number: 20240053836Abstract: An electronic pent includes a case, a core body, and a signal generation circuit. The core body is attached inside the case such that a front end portion in an axial direction protrudes from an opening portion of the case. The signal generation circuit generates a signal to be transmitted from the core body. The core body includes a core rod and a protection member that covers a pen tip portion and an axis portion of the core rod. The core body is provided with a middle portion with a dielectric constant different from a dielectric constant of the protection member, the middle portion being provided around a side surface of the axis portion of the core rod such that the core rod is separated from the protection member.Type: ApplicationFiled: October 23, 2023Publication date: February 15, 2024Inventors: Kohei TANAKA, Takenori KANEDA, Hideyuki HARA, Noboru YAMAGUCHI, Toru TSUNEKAWA

Patent number: 10820417Abstract: A display apparatus includes a display panel bendable in a bending direction about a bending axis, pad units disposed on one side of the display panel and arranged in the bendable direction, printed circuit boards disposed below the display panel, and flexible printed circuit boards configured to connect the display panel to the printed circuit boards. The printed circuit boards are bendable in the bending direction about the bending axis, are arranged in the bendable direction, and extend in the bendable direction. Each of the flexible printed circuit boards has a first end connected to the display panel and a second end connected to one of the printed circuit boards. A second distance between the second ends of two of the flexible printed circuit boards respectively connected to two adjacent printed circuit boards is greater than a first distance between the first ends of the two flexible printed circuit boards.Type: GrantFiled: July 5, 2019Date of Patent: October 27, 2020Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Jinhyuk Park, Toru Tsunekawa
