How to improve the picture quality, projection paint or projection screen is the secret

[Home Theater Network HDAV.com.cn] Good horse needs a good saddle, this sentence is familiar to everyone. Projection screens as projector accessories have not received the attention they deserve for a long time. Even so far, there are still many consumers who stubbornly believe that the projector will be installed, and the white wall can achieve satisfactory results.

For example, if you buy a Ferrari sports car, but use a low-standard gasoline, it is obvious that the sports car can not only maximize the performance, but even cause discomfort to the internal system of the sports car. The projector is also the same. If you spend a lot of money to buy a 1080p HD projector that sells for more than 100,000 yuan, but it is projected on a normal white wall, the screen effect will definitely disappoint the viewer.

Different screens have huge differences

Recently, after the market survey, the author found that the most common situation in the projector market is that when the dealer sells the projector, the Projection Screen is usually given in order to retain the consumer. Most of the presented projection screens are ordinary white plastic screens, and the price is only about 500 yuan. And if you buy a high-quality curtain separately and even need more than a thousand dollars, the purchase cost also directly affects the consumer's choice.

In fact, the projection screen as an important part of the demonstration system should be given enough attention. So, what is the difference between the effect of the white wall and the projection screen? How much difference is there between the general projector and the advanced projection screen? How do consumers choose the screen that suits their needs according to their actual situation? In doubt, the author recently walked into the projection screen merchants to conduct on-site measurements, I hope everyone can understand the importance of the projection screen.

Don't insult the projector with a white wall

Although the current use of white wall as a curtain user in the market is quite a part, I believe that if there are conditions, you should choose a curtain. Let's take a look at the difference between the effect of using the projection screen and the effect of the white wall.

The exact same light, picture, but the display on the projection screen and white wall is a completely different picture effect. In contrast, the white wall even has a serious color cast, and the projection screen is true in color and saturated in color.

Some readers will raise objections. The projection screen not only requires a certain amount of capital investment, but also installation, nursing, etc., which is too cumbersome. But if you use a white wall, there are still many problems. First of all, the white wall selected for display needs to be smooth and flat, so as to avoid the unevenness of the displayed image and affect the picture quality. Secondly, there should be no decoration on the white wall displayed, and pollution should be avoided. Otherwise, foreign objects will also affect the picture. In addition, if the decoration of the user's home is another style, the special drawing of a white wall will make the overall home style appear incompatible.

If you decide to give up the white wall, you may not be able to optimize the projector's effect because the ordinary screen is still unable to achieve the desired effect.

Why are different screens on the difference of 10,000 yuan?

In the field of high-end cinema applications, the sky-high price curtains emerge in an endless stream. I have had the privilege of seeing a screen with a price of 400,000 yuan. The same is a piece of screen size, why the price difference will be so different? Below, the author will come to understand the difference between the ordinary projection screen and the high-end screen. Here, the ordinary projection screen selected by the author is a domestic brand projection screen, and the high-end screen is the Mei Dia screen.

Flatness of different curtains

After a long suspension, it is often difficult to guarantee the flatness of the screen. We can see that the top curtain in the above picture has wrinkles under the curtain after hanging for a long time, so the wrinkles will appear when the projected image is displayed. The lower screen is more sophisticated due to the use of completely different materials. Although the same time is hanged, the flatness of the curtain remains very good.

Left is high quality curtain right, ordinary curtain

In the workmanship, there is also a big difference between high-quality curtains and ordinary curtains. For example, in the production process, the high-quality curtain on the left is a thermal polymerization process, which is also more durable in ensuring that the screen is clean and tidy. The screen on the right uses the stitching method. Due to the workmanship, we can even see that the stitched thread is clean. Once the thread is cracked, the edge of the curtain will fall off and the entire curtain will not even be used properly.

Some time ago, consumers asked the author such questions: the same two curtains claiming 100 baht, why is one screen much larger than the other one? It is understood that in the actual production process, in order to reduce costs, some manufacturers Reducing the width of the black side of the curtain, the curtain box above the curtain can also save the province. In the actual viewing process, the wide black border design atmosphere is not closed, but also helps the audience to concentrate, and after a long time of viewing, it is also conducive to the visual pressure of the audience.

Of course, there are still many differences in the different screens of motors and materials. For example, a high-performance motor is more stable and less noisy when the curtain is lifted and lowered, and a general motor is unacceptable to many users who are more demanding in noise.

The above is just a comparison between the ordinary curtain and the high-quality curtain from the material. So what is the difference between the two in terms of image quality? Below, the author will witness the difference between the two.

Real shot high quality screen to enhance projection effect

In the process of actual measurement, the two prices and performance gaps that the author chose are not disparate. Let's take a look at the effect.

The quality screen below is better than the screen above.

The quality of the high-quality curtain below is more saturated

If we distinguish it, we can see that the quality of the high-quality curtain below is higher than that of the ordinary screen above. For example, in the first picture, the blue color in the picture below is more saturated and pure, and the fins of the turtle are clearer. The upper curtain has a high gain because of its material quality, so the picture is brighter and even loses the original charm of the picture. In the green of the second picture, we can also see that although the green color in the above picture is brighter, it is obviously not as high as the green saturation in the picture below.

Some netizens have long discovered the difference between ordinary curtains and high-quality curtains. In order to let everyone know more about the difference between high-quality curtains and ordinary curtains, the author selected two pictures taken by netizens. In the two pictures above, we can see that the ordinary curtain on the left gives a gray feeling, while the screen on the right is clear and natural, and the visual effect is more shocking.

Of course, there are also relevant judgment criteria for the curtain, such as gain and viewing angle. However, in this article, the author only wants to let everyone know the difference between the white wall and the projection screen. The difference between the ordinary projection screen and the high-quality projection screen makes everyone understand the importance of purchasing the projection screen.
