### 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: Another thing, I especially hate projection manufacturers using diffuse reflection as a selling point for their eyes. Please, the light on the curtain that can be seen by the eyes is direct light for the eyes. If you diffuse it to the ceiling, your eyes can't see it. If you have to be serious, LCD TV is also diffuse "direct light." Isn't the ceiling illuminated when you turn on the TV?

### 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?
