See full text

A projection screen, with a design in which the apexes of multiple triangular pyramidal units of the projection screen in an array arrangement change gradually according to a predetermined relation, an image light shone from a projector is reflected by a microstructure layer having the triangular pyramidal units and then converged in a range centered around the human eyes, so as to reduce the degree of difference in brightness at different viewing positions, thus ensuring that the projection screen is provided with excellent uniformity and high gain.
