Many customers have purchased KOASON Android screens with wireless CARPLAY and Android AUTO functions, but they cannot see the Android screen when wearing polarized sunglasses in the car. They consulted us about this issue.

Because the Android screen uses a TFT color screen, and polarized sunglasses will filter light, resulting in the inability to see the image on the screen.

Moreover, the polarization angles of polarized sunglasses made by different manufacturers are different, which will lead to differences in the effect of seeing the display screen through some polarized sunglasses. Not all polarized sunglasses are completely black, some can be translucent, or a little transparent, but the overall effect is very poor.

If you use an OLED display, there will be no such problem, but the cost of OLED displays is too high, and no manufacturer is willing to use it, so the Android screens that can be seen on the market all use TFT displays, and there will be problems with being blocked by polarized sunglasses.

It is recommended to use regular sunglasses, which do not have this problem.
