▎ 摘　　要

NOVELTY - The device has a cover plate (30) whose outer side area is coated with sealing glue (40). A first heat conducting shielding layer (51) is coated on a bottom part of a base plate (10). A second heat conducting shielding layer (52) is formed on the cover plate that is formed with multiple protrusions (32). A side surface of a cover plate substrate (31) is fixed with an organic LED device (20). A heat conducting layer (33) is coated on the cover substrate and the protrusions. The first and second heat-conducting shielding layers are provided with a graphene and light shielding material. USE - Organic LED display device. ADVANTAGE - The device has prolonged service life and high radiating efficiency, and avoids peripheral light leakage of an OLED display device body, prevents the device body from water vapor entering, utilizes the graphene material to improve thermal conductivity and electric conductivity and improves product quality. DETAILED DESCRIPTION - The light shielding material is light-shielding adhesive or ink. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an organic led display device.
