▎ 摘  要

NOVELTY - The display panel (100) has a first substrate (1), multiple light emitting units (2), a light shielding layer (3) and a second substrate (4) which are stacked in sequence. The light-shielding layer is provided with multiple first holes (31) and multiple second holes (32) on a side facing the light-emitting unit. A color conversion layer (5) is formed in the first hole. The second substrate includes a scattering structure (40) at a position facing the second hole. The light-emitting unit corresponds to one first hole or one second hole. A material of a thermally conductive layer (6) includes a polymer matrix and thermally conductive nanoparticles. The polymer matrix includes polymethacrylate or polysiloxane. The thermally conductive nanoparticles include nanometer aluminum oxide, nanometer boron nitride, nanometer silver wire, gold nanosphere, carbon nanotube or graphene. A material of a planarization layer (7) includes polymethacrylate, polysiloxane or epoxy resin. USE - Display panel for OLED display device. ADVANTAGE - The panel improves the light emitting effect of the display device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a display panel.
