### 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 <v>a point</v>, 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, have to be more real LCD TV is also a diffuse "direct shot", open the TV ceiling is not also illuminated?
### Errors: There is a minor style/awkward error at "a point" within <v></v>.

### 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?
