This article is mainly about the related introduction of the display surface, and focuses on the detailed explanation of the difference between the display surface 1800r and 4000r.
Display curved screenCurved display refers to a display device with a curved panel, which enhances the user's visual experience. The curved display gives a wider field of view, because the slightly curved edge to the user can be closer to the user, which is basically the same as the central position of the screen. At the same time, the curved screen can make people experience a better viewing effect.
Because of the larger size of the curved screen, it has a certain degree of curvature and occupies a smaller area than the straight screen.
application
First of all, the choice of parameters and panels for curved displays is basically the same as that of ordinary flat-panel displays. The picture quality of va wide viewing angle panels is significantly better. If the budget is limited, TN panels can also be considered, but a part of the picture quality will be sacrificed. Another extremely important parameter of curved displays is curvature, which refers to the degree of curvature of the screen. For the display, the greater the curvature, the more obvious the curvature of the curvature, and the more difficult the manufacturing process. But it does not mean that the smaller the curvature, the better the visual effect. From the actual experience, it is mainly related to the size of the display. Generally speaking, the curvature of the 27-inch display should be at least 4000R or less, so at least visually. You can feel the effect of the curved surface.
The difference between the display surface 1800r and 4000r
The curvature determines the image quality and sense of presence of the curved display. The smaller the value of curvature, the greater the bending amplitude. From the perspective of the actual product market price, the smaller the curvature, the higher the manufacturing cost, and the more expensive the price is reproduced from the computer Pepsi.
From 4000R in early 2015 to 3000R and 2000R later, to the popular 1800R and the larger 1500R, the curvature is getting bigger and bigger, which also makes users experience more shocking experiences in video and games. And delicate display effect, wider field of view.
For entertainment video and audio, users especially value immersion and immersion. The smaller the curvature, the more obvious the surrounding effect the user feels. The curved display has been reprinted from the computer Pepsi.com Expo in the direction of greater curvature. The curved display can also bring a better sense of presence and substitution, especially for games and audiovisual. Compared with the flat display of the same size, the curved surface has a wider viewing angle.
But it does not mean that the smaller the curvature, the better, but also consider the size of the LCD screen and the user's best viewing distance, because if the curvature is too small, the entire screen will look distorted and uncomfortable to watch.
Therefore, only the curvature of the circle with the best viewing distance as the radius is the best curvature of the display. Now it is generally the curvature of 1800R. Not only the curvature is obvious, but it also fits the human eye. Reprinted from the computer Pepsi.
In short, for us consumers, why do we need a curved display, because the curved screen design will more closely fit the human eye’s physiological curve structure, thereby creating a zero-distortion visual experience, alleviating the viewer’s eye fatigue, and enhancing comfortability. The curved screen can create an immersive visual enjoyment for the majority of users due to the sense of envelopment on both sides.
Curvature of the display
First, you need to understand what the curvature represents. The so-called curvature refers to the degree of curvature of the screen, which is the core indicator that determines the visual effect and screen coverage of the curved display. It refers to the rotation rate of the tangent direction angle of a certain point on the curve to the arc length, which is the radius value of the curved screen.
At present, the curvature of curved displays is mainly divided into four types: 4000R, 3000R, 1800R, and 1500R, among which 4000R curvature is the degree of curvature of a circle with a radius of 4m. In the same way, 3000R curvature refers to the degree of curvature of a circle with a radius of 3m, 1800R refers to the degree of curvature of a circle with a radius of 1.8m, and 1500R refers to the degree of curvature of a circle with a radius of 1.8m. The curvature determines the image quality and sense of presence of the curved display. The smaller the curvature, the greater the curvature. Therefore, theoretically speaking, the smaller the curvature value of a curved display, the greater the curvature of the display, and relatively speaking, the better.
However, from a practical point of view, the smaller the curvature of the curved display, the higher the manufacturing cost and the more expensive the product. However, if the curvature is too small, the entire display screen will look distorted and uncomfortable to watch. Therefore, the curvature cannot be said to be as small as possible, and one degree is required.
The curvature of the circle with the best viewing distance as the radius is the best curvature of the display. Judging from the current curved display, the 1800R curvature display not only bends obviously, but also conforms to the human eye habits, so it has become the most mainstream curvature at present . However, 4000R and 3000R have been gradually eliminated due to the lack of obvious curvature of the display, and the immersion is slightly weaker. The 1500R curvature display is currently expensive, and there is a feeling of bending slightly larger, and the visual perception is likely to cause some distortion, which is not the best at present. Choice.
