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: 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
