### Chinese: 还有一点，我特别讨厌投影厂商拿漫反射对眼睛好这种当卖点，拜托，眼睛能够看到的幕布上的光线对于眼睛而言就是直射光，你漫反射到天花板上，眼睛也看不到，非要较真液晶电视也是漫“直射”，打开电视天花板不也被照亮吗？
### English: There is also a point, I especially hate the projection manufacturer to take diffuse reflection to the eyes as a selling point, please, the eyes can see the light on the curtain is direct light for the eyes, you diffuse reflection to the ceiling, the eyes can not see, <v>have to be more real </v>LCD TV is also a diffuse "direct shot", open the TV ceiling is not also illuminated?

### Improved English: Another point is that I especially hate it when projector manufacturers using “diffuse reflection is good for the eyes” as a selling point; please, eyes can see the light on the screen means that it is direct light to the eyes; when it hit the ceiling, eyes cannot see it; if you want to be serious about it, then LCD TV also uses diffused “direct light”; isn’t the ceiling also illuminated when you turn on the TV?
