The frame of the screen has an important influence on the projection effect. The black frame on the screen improves the contrast and brightness of the video and can greatly improve the visual experience. If a wall is used for projection, the entire wall is white, and the wall is white except for the picture, which reduces the visual effect. Unless the user paints the other parts of the wall into a dark color, this problem is inevitable, but Doing so affects the beauty of the home again, and it is not worth the loss.

Taking a 100-inch screen as an example, a black border greater than 5 cm can effectively avoid distracting eyes. In theory, the wider the black border, the better.
