▎ 摘  要

NOVELTY - The module (10) has a cushion plate (300) which is placed on a rear surface of the display panel (100). The cushion plate is included with an adhesive layer (310). A heat dissipation layer (320) is placed on a rear surface of the adhesive layer. A cushion portion is placed on the rear surface of the heat dissipation layer. The cushion unit (330) is included with a first heat dissipation coating layer (333a), a cushion assembly (331) and a second heat dissipation coating layer. The cushion assembly is included with a through hole (331h) connected the first heat dissipation coating layer and the second heat dissipation coating layer. The through hole is a heat dissipation assembly (335). The heat dissipation assembly is carbon black, graphite, carbon, graphene, carbon nanotube (CNT), and carbon nanofiber (CNF). The first heat dissipation coating layer and the second heat dissipation coating layer are formed of a powder made of copper (Cu), aluminum (Al), and graphite. USE - Display module for use in display device (claimed) such as TV, monitor, smart phone, tablet personal computer (PC), notebook computer, and wearable device. ADVANTAGE - The bezel area is reduced by reducing the bending radius of curvature of the display panel bent in the rear direction of the cushion plate by removing the cushion portion of cushion plate in the region disposed close to the bending portion. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of display module.
