The present disclosure provides RGB-LED packaging modules and a display screen including a substrate; a plurality of light-emitting units disposed on the substrate, each light-emitting unit including a set of RGB-LED chips; a plastic layer provided on the light-emitting units; and a virtual isolating region provided between the light-emitting units, the virtual isolating region including a black light-absorbing layer provided on the substrate. The present disclosure makes use of the black light-absorbing layer to absorb light which may cause interference among the light-emitting units. By providing the virtual isolating region and an isolating trough, and utilizing the difference of refractive index of packaging plastic and refractive index of air, light emitted by the light-emitting units can be reflected to reduce the influence of adjacent light-emitting units. A black isolating-frame is filled in the isolating trough to minimize the interference among the light-emitting units.

Disclosed is an ablation-proof structure of a solid rocket engine. The ablation-proof structure of the solid rocket engine comprises a pressure-bearing structure casing, a thermal insulating layer and an anti-scouring low-residue protective layer, wherein the thermal insulating layer is located in the pressure-bearing structure casing, and the anti-scouring low-residue protective layer is embedded into the inner surface of the thermal insulating layer. By means of the technical scheme, solid residues generated during ablation of the thermal insulating layer can be reduced, and moving parts are prevented from being blocked.
