  • Publication number: 20240032223
    Abstract: A display module and display device that may suppress a greenish defect and reduce a bezel area while improving a heat-dissipation performance and a shock absorption function include an integral cushion plate including at least one protrusion protruding from and extending along an edge portion of a body with the cushion plate placed on a lower surface of a display panel, and the protrusion brought into contact with a cover member. Further, the protrusion of the cushion plate is bent to have an inclined part so that the protrusion does not contact the side surface of the display panel and contacts the cover member.

  • Publication number: 20220394860
    Abstract: A display module and a display device including the same are disclosed. The display module includes a display panel; a metal foam layer having multiple pores formed therein; and an adhesive layer disposed between the display panel and the metal foam layer to adhere the metal foam layer to the display panel, wherein each of the display panel, the adhesive layer and the metal foam layer has at least one bendable area, wherein at least one perforated pattern is formed in the at least one bendable area of the metal foam layer.

  • Publication number: 20220209167
    Abstract: A display module and a display device which can improve a heat-dissipation performance and a shock absorption function while reducing a bezel area include a cushion plate with a metal foam that has both a heat-dissipation function and a cushion function, so that both of an effective heat-dissipation function and an effective cushion function can be realized only using the metal foam without addition of a separate heat-dissipation layer or cushion layer. Further, the metal foam of the cushion plate has very excellent heat-dissipation function and cushioning function at only a small thickness thereof, so that a total thickness of the cushion plate can be greatly reduced, and the bezel area can be reduced.
