Patent number: 11982462Abstract: An air conditioner includes a cabinet including an inlet port and a frame including an outlet port and coupled to the cabinet. A heat exchanger is disposed between the cabinet and the frame to exchange heat with air introduced into the inlet port and discharged to the outlet port. A blocking member is configured to connect the frame and the heat exchanger to prevent air heat-exchanged with the heat exchanger from leaking into the cabinet. This structure inhibits dew from being generated on the cabinet.Type: GrantFiled: October 8, 2019Date of Patent: May 14, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Chang-Woo Jung, Sung Jae Kim, Jin-Gyun Kim, Young Tae Song, Hae Gyun Shin, Chang Sik Lee, Seo Young Cho, Sung Hyun Chun

Patent number: 11782565Abstract: Disclosed is a display device having touch sensors which may improve visibility. In the display device, the touch sensors having a multilayer structure including a blackened layer are arranged on an encapsulation assembly arranged to cover light emitting elements, and touch pads having a multilayer structure including a partially transparent conductive layer are arranged on a region of a substrate exposed by the encapsulation assembly. Therefore, the blackened layer may prevent reflection of external light and thus visibility may be improved, and the partially transparent conductive layer may lower sheet resistance of the touch pads and thus contact resistance between the touch pads and a driver integrated circuit may be reduced.Type: GrantFiled: March 16, 2022Date of Patent: October 10, 2023Assignee: LG Display Co., Ltd.Inventors: Yong-Il Kim, Chang-Hyun Song

Patent number: 11620012Abstract: Disclosed is a display device capable of reducing the thickness and the weigh thereof. A display device having a touch sensor realizes electrical connection of a routing line and a touch pad via an auxiliary conductive layer, which is connected to the routing line under an encapsulation unit, even if a disconnection fault occurs in the routing line, thereby achieving increased yield and reliability. In addition, through the provision of a touch sensor disposed above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.Type: GrantFiled: November 24, 2021Date of Patent: April 4, 2023Assignee: LG Display Co., Ltd.Inventors: Chang-Hyun Song, Jeong-Oh Kim
