Abstract

The invention relates to a projection screen regulator. The projection screen regulator includes a frame, a screen bolt is fixed on the frame, and the upper end of the screen bolt is clamped by a first hand-shaped clamping jaw and a second hand-shaped clamping jaw; the first hand-shaped clamping jaw is connected with a first steering engine through a single universal coupling, and the second hand-shaped clamping jaw is connected with a second steering engine; both the first steering engine and the second steering engine are connected with a signal generator, and the first steering engine enables the first hand-shaped clamping jaw to drive the screen bolt to perform regulation through the single universal coupling in a front-back direction under the control of the signal generator; and the second steering engine enables the second hand-shaped clamping jaw to drive the screen bolt to perform regulation in a left-right direction under the control of the signal generator. The projection screen regulator provided by the invention can achieve a relatively high reflection condition, and generates high-quality pictures.

Description

technical field [0001] The invention relates to the technical field of shadow screen adjustment, in particular to a shadow screen adjuster. Background technique [0002] A projector is a projection device used to magnify and display an image. Projection display is a display method that projects an image on an auxiliary surface. The optical instrument on the screen has the remarkable feature that the display surface is separated from its own equipment, so that it has the advantage that the size of the display screen is not restricted by the size of its own equipment and can realize the combination and superposition display of multiple screens. As a mainstream display technology, projection display plays an important role in all stages of the development of the display field by virtue of its large-size screen advantages. It has developed from a single traditional CRT technology to a modern projection display technology in which multiple technologies coexist. And present the c...
