Q: My children's projector looks like it has a layer of sand on it.It makes my customer experience very bad.Do you have a better screen?I'm going to the exhibition soon.
Answer: this is easy to solve :1. Change the polarizer of smooth surface is ok.Polarizer has smooth surface and ground surface two kinds of material.The thickness is also different. A thickness of 0.23mm can increase the visual Angle.More public polaroid after must remember to defoaming, so polaroid will not fall off.2. Please check whether the lens of the projector matches.
