TECHNICAL FIELD

The present disclosure relates to the field of projection display technologies, and in particular, to a projection screen and a projection system.

BACKGROUND

With the continuous development of science and technology, projection display systems are increasingly applied to people's work and life. Laser projection is gradually occupying the market because of its advantages such as wide color gamut, high brightness, and long service life.

SUMMARY

In one aspect, a projection screen is provided, which includes a screen board, a connecting cloth, a screen frame, and at least one connection member. The screen board has a first surface and a second surface opposite to each other. The screen board has a light receiving region and an edge region surrounding the light receiving region. The connecting cloth is disposed on the second surface of the screen board. At least one edge of the connecting cloth protrudes from a corresponding edge of the screen board. At least a portion of the second surface of the screen board located in the edge region is connected to the connecting cloth. The screen frame has a hollow structure. An orthographic projection of the screen board on a plane parallel to the first surface is located within an outer border of an orthographic projection of the screen frame on the plane. Each edge of the connecting cloth being connected to the screen frame. The at least one connecting member connects the at least one edge of the connecting cloth to the screen frame, and the at least one connecting member is configured to provide a tension to the connecting cloth.

In another aspect, a projection system is provided, including a projection device and the projection screen as described above. The projection device is configured to project images onto the screen board of the projection screen.
