Abstract

The invention discloses a seamless spherical projecting screen and a manufacturing method thereof. A mould sinking type spherical mould is subjected to rotational moulding treatment by adopting a rotational moulding machine, so that rotational moulding materials positioned in the mould are uniformly diverted and solidified under a certain temperature and time, thereby achieving the purpose that the projecting screen is processed at one time and wholly formed and avoiding the defects that the prior optical additive spherical projecting screen is required to be spliced, and splicing seams on the surface influence the projection effect. Because the rotational moulding materials are dispersed in a resin body with a certain thickness, the projection effect is better than the effect of a thin coating layer, and an image is clear and is not distorted. The processed finished projecting screen has smooth and level surface, attractive appearance and remarkably improved projection effect and projection quality and is particularly suitable for occasions with special display effect.

Description

technical field

[0001] The invention relates to a spherical projection screen, which belongs to the technical field of electronic equipment, in particular to a seamless spherical projection screen without splicing and one-time molding and a manufacturing method thereof. Background technique

[0002] As projection devices are accepted by consumers, the fields of application of projection devices are also expanding and improving. Projection screens account for the largest proportion of projection equipment. At present, the common projection screens on the market are divided into two types: front projection and rear projection. It occupies a small area, so it is deeply loved by consumers. But in some special occasions, when special effects are required, this kind of projection screen obviously cannot meet the needs of use. With the advancement of science and technology, in recent years, a display platform with three-dimensional projection as the display effect-spherical proje...
