In these two days, I have been chatting with everyone about ultra-short-focus laser televisions in Mijia and Chaoji. Many friends do not understand why such laser televisions must use special anti-light curtains, but also friends asked whether it is possible to use white curtains or curtains used in traditional projectors. In fact, if you choose an ultra-short-focus laser television placed on a wall, and you also want to get the effect of not turning on the lights at night and watching the brightness of the screen close to a traditional flat-screen TV, you must The use of a light curtain developed specifically for this type of ultra-short-focus laser television is justified. 
Just this afternoon, my friend installed a 120-inch light-resistant curtain on the Internet for his family's Mijia Laser TV. He asked me to send a few photos to me. Let's look at it together. The first is the effect comparison:
The first one is the effect when the screen is not used. The following is the effect of using the screen. Although the photos taken by the two photo friends are different in photometry, the difference is indeed very obvious.
Why does this special anti-light curtain have such a magical effect? I found a text description on the Internet:
Directional-reflective (black-grid) anti-light screen (reflex ultra-short-focus projector)
The principle of this type of screen is to use a special process to produce a screen with a zigzag cross section. The base material is made of dark color material, and a white reflective coating is applied on the serrated oblique edge to reflect the incident light horizontally toward the viewing area, while the top surface and the side surface of the ambient light are absorbed by the dark color base material. The means to reduce the impact of ambient light on the screen. This type of screen is a newly developed screen that must be used with a reflective ultra-short throw projector.
Please note that the "Hisense TV Light Curtain" mentioned in this article is a special 100-inch Fresnel lens hard screen (can not be curled, transport and installation is a large flat panel). The market price of this curtain should be around 10,000 yuan, which is much more expensive than the black-grid type of anti-light curtain we are currently talking about.
It is because of such a special optical structure that laser television products have achieved a very good daytime/lighting environment viewing effect on such specialized light curtains. The use of white walls or traditional curtains cannot achieve the same results unless you only use laser televisions in a dark environment - but this is not a waste of the biggest reason why laser televisions are not called "projection" and are called "televisions". Advantage? In addition, because such ultra-short focal projection has very high requirements on the flatness of the curtain, a slight unevenness can easily lead to distortion of the image, so the traditional electric roller blind curtain or a very flat white wall (even if the naked eye feels flat In this respect, it cannot be compared with a professional light curtain that uses a frame structure to stretch the surface.
The problem is that the cost of laser televisions in such an excellent day is that professional anti-light curtains are expensive. Here are a few of today's workers on-site construction pictures and order prices for my friend's curtain. Therefore, it may be that many friends see the propaganda after the Mi Jia laser television, as long as 9999 yuan will be able to see the projection in the daytime. You must be prepared to pay close to several thousand or even ten thousand yuan. This is very different from playing traditional projection (entry level), which can be relatively cheap or even directly throwing a white wall. After all, it is basically used in a dark light environment without the need for such a light curtain with complex optical structures. Of course, the price of a genuine fever-class traditional projection screen is also very expensive. A few thousand dollars is just the starting price and tens of thousands is also just better. There is no special development here.
Think about it, to buy a laser television but also with a suitable curtain, in fact, a bit like using our photographic equipment:
You compare a laser television/projector host to a single-lens or micro-single body, and the curtain is the lens. If you have a good body, but you don't have a good lens, it's hard to get the best results. I have always said that the allocation of a reasonable budget for a SLR is 2/3 of the fuselage, and the lens must account for at least 1/3 or more. While playing laser television, the price match between the host and the curtain is basically the same. A laser TV similar to Mijia's 9999 yuan will be equipped with a 4-5000 yuan 100-inch light-resistant screen to maximize its effectiveness, and the 120-inch screen curtain effect like my friend is certainly more shocking. When the laser television is sold, the price of the curtain is directly included in the price, which is also to guarantee its final effect.
what? You said that the total price of the curtain + host must be one or two thousand yuan, and the price can buy a 75-inch Dafa TV! Yes, if you feel that 75-inch screens can satisfy that natural selection of flat-screen TVs. But what we are talking about is a 100-inch or even 120-inch large screen! I believe that after you understand the differences in the sizes of these screens, you will be deeply attracted by the larger screens. The question is, do you know what a 100-inch or 120-inch flat-panel TV will be?
