Abstract
An oriented light intensifying and anti-ambient light projection screen for short-focus projection equipment is characterized by including a transparent substrate and a coating layer for projection and imaging. The surface of one side of the transparent substrate is in a zigzag shape. The coating layer coats or is sprayed onto the zigzag surface of the transparent substrate and fits the zigzag surface of the transparent substrate. Therefore, during use, the projection light can pass through the transparent substrate, irradiates on the slope imaging coating layer and is reflected in an oriented manner, so that the reflection light can be more focused on the viewing center, and an effect of light intensification is fulfilled. In addition, because imaging is performed on the zigzag slope coating layer, the ambient light obliquely from above is shielded by the plane of a zigzag projection face, and the projection light from the front or obliquely from a lower place forms an image on the slope, the imaged picture on the slope is free from the interference of the ambient light. Accordingly, a human eye can see an imaged picture which is clearer and has higher contract and higher brightness, and user experience is improved.
