Publication number: 20240423017Abstract: Disclosed are a display module and a display device capable of minimizing a pressed stain defect while reducing a bezel area. To this end, a thickness of a cushion portion of a cushion plate closer to a bent portion may be reduced, thereby reducing a bending radius of curvature such that the bezel area may be reduced. Further, placing a support layer having a strong supporting force formed of PET into the cushion plate such that the support layer is in contact with the heat-dissipation layer may allow minimizing an unevenness defect on the cushion plate even when a bent pad portion of a display panel presses the cushion portion. Thus, visibility of an internal pressed stain to a user may be minimized.Type: ApplicationFiled: August 26, 2024Publication date: December 19, 2024Inventors: Jongseok CHA, Dongwon JANG, Buhui LEE, Junho YUN

Patent number: 12114442Abstract: Disclosed are a cushion plate and a display device including the same. The cushion plate includes an impact-absorbing layer disposed on a back surface of a display panel, a first metal layer disposed on upper portion of the impact-absorbing layer, and a second metal layer formed on upper portion of the first metal layer and having a higher thermal conductivity than the first metal layer. The impact-absorbing layer, the first metal layer, and the second metal layer have a first curvature area, and at least one perforated pattern is defined in an area of the first metal layer corresponding to the first curvature area.Type: GrantFiled: May 25, 2022Date of Patent: October 8, 2024Assignee: LG Display Co., Ltd.Inventors: Buhui Lee, Wangeon Sim, Kyoung-Hoon Kim, Kwangju Lee

Patent number: 11856741Abstract: A display apparatus capable of improving heat-dissipation performance while not increasing a total thickness thereof include a heat-dissipation member accommodated in a cushion plate. Thus, the heat-dissipation performance may be improved without increasing a thickness of the display apparatus. Thus, a mounting space for components may be secured without increasing a bezel area. Further, the heat-dissipation member having a predetermined thickness and an air gap are disposed in the heat-dissipation member accommodating space of the cushion plate, thereby maximizing the heat-dissipation from a driving integrated circuit disposed under the cushion plate so as to overlap the heat-dissipation member accommodating space.Type: GrantFiled: August 13, 2021Date of Patent: December 26, 2023Assignee: LG Display Co., Ltd.Inventors: Buhui Lee, Sangsoo Yoon, Dongwon Jang, Jongseok Cha
