This paper mainly introduces the display surface, and focuses on the differences between the display surface 1800r and 4000R.

Display curved screen

Curved display refers to a display device with an arc on the panel, which improves the breadth of the user’s visual experience. Curved display gives people a wider field of vision, because the edge slightly bent towards the user can be closer to the user, and the viewing angle is basically the same as the central position of the screen. At the same time, curved display allows people to experience a better viewing effect.

Due to its larger size, curved screen has a certain degree of curvature and occupies a smaller area than straight screen.

application

First of all, the selection of parameters and panels of curved panel display is basically the same as that of ordinary flat panel display. The image quality of VA wide view panel is obviously better. If the budget is limited, TN panel can also be considered, but it is relatively necessary to sacrifice some of the image quality. Another extremely important parameter of curved surface display is the curvature, which refers to the bending degree of the screen. For the display, the greater the curvature is, the more obvious the bending radian is, and the manufacturing process is more difficult. However, it does not mean that the smaller the curvature is, the better the visual effect will be. From the actual experience, it is mainly related to the size of the display. Generally speaking, the curvature of a 27 inch display should be at least within 4000R, so that at least the visual effect brought by the surface can be felt.

Difference between display surface 1800r and 4000R

Curvature determines the image quality and sense of scene of curved display. The smaller the value of curvature, the greater the bending amplitude. From the perspective of actual product market price, the smaller the curvature is, the higher the manufacturing cost is, and the more expensive the price is reprinted from Pepsi.

From the 4000R at the beginning of 2015 to the later 3000r and 2000r, to the current popular 1800r and the larger arc 1500r, the curvature is also getting larger and larger, which also enables users to experience a more shocking and delicate display effect and a wider field of vision in both video and games.

For entertainment audio and video, users pay special attention to the sense of immersion and bringing in. The smaller the curvature, the more obvious the surrounding effect the users feel. The curved display has been reprinted from the computer Pepsi online exhibition in the direction of large curvature. Curved displays can also bring a better sense of presence and substitution, especially for games and audio and video. Compared with flat-panel displays of the same size, curved displays have a broader perspective.

However, it does not mean that the smaller the curvature is, the better. It also needs to consider the size of the LCD screen and the best viewing distance of the user, because if the curvature is too small, the whole picture will look deformed and uncomfortable to watch.

Therefore, only the curvature of the circle with the radius of the best audio-visual distance is the best curvature of the display. Now, the curvature is generally 1800r, which is not only obviously curved, but also adapted to the human eye habit and reproduced from PepsiCo.

In short, for our consumers, why do we need a curved display? Because the curved screen design will better fit the physiological curve structure of the human eye, so as to create a zero distortion visual experience, alleviate the eye fatigue of the viewer and enhance the comfort. The curved screen can create an immersive visual enjoyment for the majority of users due to the surrounding feeling on both sides.

Curvature of the display

First, you need to know what curvature represents. The so-called curvature refers to the bending degree of the screen, which is the core index to determine the visual effect and picture coverage of the curved display. It refers to the rotation rate of the tangent direction angle of a point on the curve to the arc length, that is, the radius value of the curved screen.

At present, the curvatures of curved surface display are mainly divided into four types: 4000R, 3000r, 1800r and 1500r. Among them, 4000R curvature is the degree of bending of a circle with a radius of 4m. Similarly, 3000r curvature refers to the bending degree of a circle with a radius of 3M, 1800r refers to the bending degree of a circle with a radius of 1.8m, and 1500r refers to the bending degree of a circle with a radius of 1.8m. Curvature determines the image quality and sense of scene of curved surface display. The smaller the value of curvature, the greater the bending range. Therefore, in theory, the smaller the curvature value of the curved display, the greater the radian of the display. Relatively speaking, it is better.

However, from a practical point of view, the smaller the curvature of curved display, the higher the manufacturing cost, and the more expensive the product price. However, if the curvature is too small, the whole display will look deformed and uncomfortable. Therefore, the smaller the curvature is, the better. It still needs a degree.

The best curvature of the display is the curvature of the circle with the radius of the best audio-visual distance. From the current curved surface display, the curvature display of 1800r not only bends obviously, but also fits the habits of the human eye, so it has become the most mainstream curvature at present. The 4000R and 3000r monitors have been gradually eliminated due to their slight bending and weak immersion. However, the 1500r curvature monitors are expensive at present, and there is a feeling that the bending is slightly too large. The visual sense is easy to cause some distortion, which is not the best choice at present.
