Patent number: 11494021Abstract: Embodiments of the disclosure relate to touch display devices. Display pads and touch pads may be arranged on the same side of a display panel by removing a portion of a second substrate to thereby expose the touch pads to the outside after attaching the second substrate on which the touch pads are arranged to a first substrate on which the display pads are arranged. Since the touch pads are positioned higher than the display pads in the area that does not overlap the display pads, bonding between the pads and the printed circuit may be easy to perform. Since the number of pads that may be arranged increases, it is possible to easily implement a large-area, high resolution touch display device.Type: GrantFiled: August 25, 2021Date of Patent: November 8, 2022Assignee: LG Display Co., Ltd.Inventors: YoungJun Hong, BooYoung Kim, SeongHoon Kim

Patent number: 7632352Abstract: Provided is a spin coating apparatus having a ring-shaped or polygonal auxiliary member for use in manufacture of a coated substrate via spin coating, wherein the auxiliary member is positioned adjacent to the side of a substrate for coating, within a range of a spaced distance of 0.03 to 0.8 mm and a range of a height deviation of less than 0.1 mm, upon mounting the substrate. When a surface of a substrate for coating is spin coated with a coating agent using the apparatus of the present invention, it is possible to eliminate or effectively reduce a ski-jump phenomenon at end portions of a coated substrate occurring when spin coating is performed, thereby resulting in uniform coating of a coating solution on the substrate, and it is also possible to effectively decrease contamination of the substrate for coating due to inflow or stay of the remaining coating agent.Type: GrantFiled: December 9, 2005Date of Patent: December 15, 2009Assignee: LG Chem, Ltd.Inventors: Tae-sik Kang, Seongkeun Lee, Youngjun Hong
