序章
In the practical application of LED表示, you may encounter a problem: Even if it is the same LED display, why is the audience’s viewing experience so different in different scenarios? Among them, the influence of perspective cannot be ignored.
So, how is the perspective of LED defined? How to adjust? This article will give you the answer.
1. What is the viewing angle of LED display
の 視野角 of the LED display refers to the angle range where users can clearly observe all the content on the screen from different directions. This angle range usually includes both horizontal and vertical directions. Specifically, the horizontal viewing angle is based on the vertical normal of the LED display (that is, the vertical imaginary line in the middle of the LED display).
Within a certain angle range on the left or right side of the normal line, users can see the displayed image normally. Similarly, the vertical viewing angle is based on the horizontal norma, with an angle range of the upper and lower directions.
In short, when we look at the screen from different directions, we can clearly see the angle range of the above content. This range includes two directions, from left to right and from top to bottom. Just like when we watch TV or a computer screen, if we stand on the side or look at it, we may not be able to see the content on the screen clearly, which is because of the limitation of the viewing angle.
The viewing angle of the LED display is mainly determined by the packaging method of the LED lamp beads and the distance we watch the screen. Generally speaking, the larger the perspective, the clearer the screen content we see from different angles. However, when the viewing angle is increased to a certain extent, the content on the screen may become blurred.
The viewing angle is very important when choosing an LED display, especially on some specific occasions, such as outdoor billboards, stadiums, conference rooms, etc. In these places, people may look at the screen from different directions, so the size of the perspective is particularly important.
If the perspective is too small, the person standing on the side or above the screen may not be able to see the content on the screen clearly, which will affect the viewing experience.
2. What is the impact of the viewing angle on the display of the LED display?
The viewing angle has a great impact on the display of the LED display. In short, the perspective determines the angle range from which we can clearly see the content of the screen when we look at the LED display from different directions. Specifically, the viewing angle has an impact on the display of the LED display in the following aspects:
- Viewing experience:
The larger the viewing angle, the better the experience the audience gets when watching the LED display from different angles. If the viewing angle is insufficient, the person standing on the side or above the screen may see blurred or distorted images, which will affect the viewing effect.
- Image quality performance:
The size of the viewing angle will also affect the image quality performance of the LED display. When the viewing angle increases, the distance between the pixels on the screen will become larger, resulting in a decrease in the image resolution, which will affect the clarity of the image quality. In addition, too large a viewing angle may also lead to color distortion, which will affect the color performance of the image.
- Application scenario adaptability:
Different application scenarios have different requirements for the viewing angle of the LED display. For example, in public places such as outdoor billboards, a larger perspective is needed to ensure that pedestrians can see clear advertising content from different angles.
In indoor places such as conference rooms, because the audience is close to the screen, the demand for perspective is relatively small. Therefore, when selecting the LED display, it is necessary to determine the appropriate viewing angle according to the actual application scenario.
3. What are the factors that affect the viewing angle of the LED display?
The main factors affecting the viewing angle of the LED display are as follows:
The packaging method of LED lamp beads: The packaging method of LED lamp beads determines the viewing angle of the LED display. Generally speaking, the more advanced the packaging method, the larger the luminous angle of the LED lamp beads and, thus, the larger the viewing angle of the LED display screen.
Quality of LED chip: The quality of the LED chip will also affect the viewing angle of the LED display. High-quality LED chips usually have higher luminous efficiency and more stable luminous performance, thus providing a larger viewing angle.
Surface flatness of the screen: The surface flatness of the LED display will also affect the viewing angle. If there is unevenness on the surface of the screen, the image may be distorted or distorted when viewed from different angles, thus reducing the viewing angle.
視聴距離: The viewing distance will also affect the viewing angle of the LED display. Generally speaking, the farther the viewing distance, the greater the perspective required. Therefore, when selecting the LED display, it is necessary to determine the appropriate viewing angle according to the actual viewing distance.
Screen brightness: Screen brightness also affects the viewing angle. Generally speaking, the higher the brightness of the LED display, the higher the viewing angle will increase accordingly. Because when the brightness is high enough, it can maintain good image clarity even when viewed at a large angle.
4. Measures to improve the viewing angle of LED display
- Optimize LED bead packaging:
Improve the packaging method of LED lamp beads and adopt more advanced packaging technology to increase the luminous angle of LED lamp beads. This can effectively expand the viewing angle of the LED display so that the audience can get a better viewing experience from different angles.
Imagine that the LED bead is like a small light bulb. By improving its packaging method, the small light bulb can emit a wider range so that more people can see the content on the screen.
- Choose a high-quality LED chip:
The use of high-quality LED chips can improve the luminous efficiency and stability of the LED display, thus increasing the viewing angle. High-quality LED chips usually have higher brightness and a wider color gamut, which can provide clearer and more realistic images.
The LED chip is the core part of the display, just like the heart of the TV. Choosing a high-quality LED chip is like installing a strong heart on the TV, which can make the display brighter and brighter in color and see more clearly.
- Improve the surface flatness of the screen:
Optimize the production process of the LED display to ensure that the surface flatness of the screen reaches the best state. This can effectively reduce image distortion or distortion when viewing from different angles, thus improving the viewing angle.
If the surface of the screen is uneven, like an uneven mirror, the reflected image will be distorted. Therefore, keeping the surface of the screen flat is like reflecting a clearer image with a smooth mirror.
- Adjust the viewing distance and angle:
According to the actual application scenario, reasonably adjust the viewing distance and angle of the LED display. By adjusting the viewing distance and angle, the audience can watch the LED display from the best perspective to get a better viewing effect.
Sometimes, you stand too far or too far to see the content on the screen. Adjusting the viewing distance and angle is like adjusting the camera lens so that you can see the content on the screen more clearly.
結論
With the continuous progress of technology, we expect that the perspective of the LED display can be greatly improved to meet the needs of more different scenarios.
