Private cinema—— professional customization
The acoustically transparent screen adopts a double-layer structure, the front side is an imaging layer, the back side is a light shading and width shading layer, and the frame adopts a double-layer slideway installation mode, so that the acoustically transparent screen has excellent picture color while having a complete sound effect.
It is a new generation of high-definition image screen carefully developed according to the radian of human eyeball. Based on the principle of single-point light source plane scattering precision focusing, the advanced aluminum numerical control bending technology is used to solve the focus blur phenomenon caused by the different projection distance between the projector lens and the screen, which brings more detailed and magnificent visual enjoyment to the audience who enjoy the wide screen.

More detailed and realistic visual enjoyment
It is developed according to the visual characteristics of human eyeball to light, effectively balancing the focal length of each
point on the screen, and perfectly matching the screen image with the vision.
More uniform and detailed picture presentation
The lens of the projector is spherical. By changing the horizontal radian of the screen, the distance between each point of the
screen and the projection lens is approximately equal, and the center and periphery of the image are focused clearly.

FAQ
1. How to correctly calculate the correct size of the projection screen at your installation site? (Or whether the screen size expected to be purchased is in line with the installation size at the site?)
The border width is added to the calculation.
According to the width and height of the screen reserved for installation on site, the proportion of the projection screen is calculated (16:9, 2.35: 1).
（1）Calculate the size of the projection screen according to the height and proportion, and calculate the corresponding width according to the size to see if it matches the width installed on site.
（2） Calculate the size of the projection screen according to the width and proportion, and calculate the corresponding height according to the size to see if it is consistent with the height installed on site.
According to the calculated result, the projection screen can be customized by taking the size that the height and width can meet.
2. How to calculate the height of the black edge on the electric screen?
The length of the black edge on the electric projection screen is determined according to the floor height of the audio-visual room, because the projection area is fixed, when the floor height of the audio-visual room is higher, the height of the upper black edge is increased appropriately to meet the best viewing effect. When the height of the audio-visual room is too high, it is recommended to use the second lifting to meet the best viewing effect.
3. How big can the projection screen be?
3. How big can the projection screen be?
（1）The frame white projection screen can be infinitely large.
（2）The maximum size of the frame woven acoustically transparent projection screen is 228 inches（16:9）.
（3） that microporous sound-transmitting projection screen can be splice infinitely, and the size is not limited.
4. What is the recommended size of the arc screen?
Generally, it is not recommended to consider the arc screen within 150 inches, because the size is small and the effect of plane and arc is not very different. The specific size needs to be determined by taking into account the customer's budget, site conditions and the projector used.
5. Calculation formula for different proportions of projection screen?
（1）Calculation formula of scale 16:9,
Width=size*0.87155*25.4
High=size*0.49*25.4
（2) Calculation formula of scale 2.35:1,
Width=size*0.92*25.4
High=size*0.39166*25.4
High=size*0.39166*25.4
6. How to determine the viewing distance?
Calculated as 1.5 times the width of the projection screen.
7. How long is the lead time?
7-14 days.
8. Do you provide samples?
Samples can be provided free of charge, and customers need to pay for transportation.
9. How long is the service life of the curtain? Will it be deformed after a long time of use?
The temperature of our curtain is between -10 ℃ and 40 ℃, and the relative humidity is between 40% and 70% RH (except for man-made damage). It will not deform after long-term use, and its service life is guaranteed to be more than 10 years.
