The display principle of LED sphere screen and traditional display screen is different, this difference is not only in its appearance and display effect, but also reflected in the display principle and video processing method. This article will explore the display principle of LED sphere screens and how to handle video.

First of all, let's understand the display principle of LED sphere screen. The LED sphere screen is composed of many small LED light beads that are arranged on the surface of the sphere. By controlling the brightness and color of LED beads in different areas, the sphere screen can achieve a colorful display effect. Unlike the traditional display, the LED sphere screen is able to present a full range of perspectives, so that the audience can get a good visual experience from different angles.

However, due to the special shape of the LED sphere screen, how to handle video becomes a challenge. In the traditional flat display, we can directly input the video signal into the display screen, and then through the control of pixels to achieve the display of the picture. On the LED sphere screen, more complex video processing is required.

The most basic method of video processing is to convert the video signal into the format required for the sphere screen. Because the display surface of the sphere screen is curved, the video signal needs to be bent and corrected to display correctly on the screen. When the video signal is input to the LED sphere screen, the system will process and adjust the video signal according to the shape and size of the screen to ensure that the display effect of the picture on the sphere screen is accurate.

Another issue that needs to be addressed is the resolution of the LED sphere screen. Due to the special shape of the sphere screen, its resolution is not simply expressed in horizontal and vertical pixels like the traditional flat display. In order to better adapt to the shape of the sphere screen, the calculation of its resolution needs to consider the radius of the sphere, arc length and other factors. Therefore, when processing video, it is necessary to set the resolution and pixel density according to the specific parameters of the sphere screen to achieve the best display effect.

In addition, in order to make the video more smooth and realistic on the LED sphere screen, the video also needs to be properly adjusted and optimized. This may involve processing aspects such as color correction, dynamic range control, brightness adjustment, etc. Through these processing, the video picture can be presented in a better effect on the sphere screen, and achieve a better viewing experience.
