The reason why the polarizer is replaced is that the polarizer facing the eyes of the ordinary liquid crystal display is frosted to dissipate the surface reflection and scatter the light to increase the viewing angle of the liquid crystal display{{0}} for the projector, any scattering will cause the loss of light. The ideal state of the liquid wafer used in the projector should be 0℃angle of view, that is, if you look at the liquid wafer from the vertical direction, there will be no light. Of course, this is impossible to achieve, but the closer the angle of view is to 0 degree, the higher the utilization rate of light is. Therefore, after replacing the frosted polarizer with a flat light polarizer, the brightness of the projector to the wall will be greatly improved, my personal estimation is that it can increase by 50-80%, which is the reason why Polarizer ka kan ka Changé.
