I believe that there are many small partners in the hands of the home projector, there are entanglements in whether to add another curtain doubts, the following Lingying will come to talk to you about the need to talk about the end of it.
First of all, the projection screen must have its existence value, compared with the ordinary white wall, the projection screen has significant advantages, the screen reflects the ability to reflect incident light, can improve the brightness of the picture, through the clever processing of light, you can also change the black position effect of the picture, enhance the contrast of the picture.
White walls are difficult to achieve this effect, coupled with the fact that the wall is easy to pollute, or the texture of the wall itself will have a certain impact on the projection picture. In addition, the white wall does not have a "black edge", when watching, the attention and picture contrast is not as high as the curtain with black edges, and the visual quality of the picture itself will be slightly lower.
Of course, it takes a high-quality projection screen to have such an effect, and the cheap inferior screen effect is often difficult to say.
In general, the overall color of the curtain is more harmonious, the picture is softer, the black position performance is better, and the image reflected in the white wall is brighter, although it cannot replace the projection screen, but the overall viewing effect projected onto the white wall is also good.
If you have high requirements for picture quality and sufficient budget, you can buy a high-quality projection screen, which can harvest a better viewing experience, but if you do not have high requirements for picture quality and the funds are a little tight, you do not have to buy a projection screen to watch movies, and you can directly cast it on the white wall to watch.
