Projector Screen Evaluation: White Fiberglass vs. Ambient Light Projection Screen Evaluation (daytime vs. night)

1.The projector screen is greatly affected by the ambient light, so the performance of the same curtain in different environments is different, so don’t be true.

2. There are two projectors at home, one LED is H2, and the other is BenQ W1120. Today, XGIMI H2 is used as the test light source. 

What kind of screen is suitable for LED projector?

[Common screen fabric are mainly divided into the following categories]

Matte White Fabric: advantages-cheap Disadvantages: the overall color is white, the color reproduction is poor, basically the same as the white wall

Flexible white Fabric : Advantages-large brightness improvement Disadvantages: high requirements for the projection position of the machine, must be front projection; low viewing angle, the best viewing angle is the imperial seat with 1-2 people in the center

Anti-light screen: Advantages-anti-light effects during the day, high color reproduction Disadvantages: will reduce the brightness of the picture 

So,Is LED projector suitable for buying anti-light curtain? The answer is yes. —— But there is a premise. The LED brightness is recommended to be above 1000. I have tried five or six hundred brightness micro-projectors. I think I can just give up using anti-light curtains and just cast a white wall.

Introduce the test machine used today-XGIMI H2 (official parameter: brightness 1350) 

Testing start:

Daytime—— Comparison of three kinds of curtains (the bottom is the existing anti-light curtain, the upper left white glass fiber, the upper right new anti-light projector screen)

Absolute daytime, no holidays, windows on the left, plenty of optical fiber

Green 1 Green 2 purpleBlue White Mixed color

The above is a comparison of pure color pictures, the conclusion is obvious: —— White glass fiber has high brightness, but it is white, and I won’t talk about the color —— The old anti-light curtain has low brightness and dark, but the color is better than white glass fiber —— Not much to say about the new effect, I think it’s quite obvious

Start to compare different pictures below: Summary: I dislike it when I compare the white fiberglass. I won’t say the conclusion. Let’s look at the picture for yourself. The comparison is quite obvious. To ensure fairness, I took a photo of the window on the right. There are windows on both sides. So the light in the room is absolutely sufficient. Although there is no direct sunlight, the direct sunlight is worse than that, and the curtain is white even if it is awesome. 

Comparison of lighting off environment at night —— After turning off the light, the color of the two anti-light curtains is better than that of white glass fiber. The disadvantage of white glass fiber is just as I said at the beginning, which is white.

Comparison of lighting on  at night

The comparison is all over. Everyone has different opinions, so I won’t say more. . . —— Don’t blame the poor projection, a good horse is equipped with a good saddle, I spent thousands on buying a machine, it’s not bad that a little bit of green onion cost money, it was cool when I bought it, and I bought it always cool. Projector screen evaluation: white glass fiber Vs Evaluation of two anti-light curtains (daytime vs. nighttime) —— There is no problem in the viewing angle of this screen within 160°, and there is no problem in normal use.
