Have you ever seen a spherical LED display? The world’s largest spherical LED display to date. This giant spherical LED display in Las Vegas has attracted a lot of attention.
We can also see spherical LED displays of various sizes in our daily lives. How much do you know about this creative LED display? Read the article below and let’s explore the spherical LED display together.
1. Types of Spherical LED Displays
According to the structure and shape of the LED screen, it can be divided into the following types
Watermelon Rind LED Spherical Screen
Imagine the scene of cutting a watermelon, each piece is curved, similar to the segment of an orange. Put these “watermelon rind”-shaped circuit boards together to form a ball. This is the basic structure of the watermelon rind LED spherical screen.
The advantage of this screen is that the structure is simple and easy to understand, but due to the limitation of the “watermelon rind” shape, the screen is at the two poles of the ball, resulting in a relatively low image utilization rate of the entire screen.
Triangular LED Spherical Screen
A football is made up of multiple small faces, each of which is a triangle. By splicing these triangular circuit boards together, a ball can also be formed, which is a football-shaped LED spherical screen.
This screen solves the problem of poor display effect of watermelon peel screens at the poles, because small triangles are used to fill these gaps, greatly improving the utilization efficiency of the screen. However, due to the diversity of triangle shapes and sizes, making this screen requires many different types of circuit boards, and programming will be more complicated.
Six-Sided LED Spherical Screen
The Rubik’s Cube has six faces, each of which is a square. If each face of the Rubik’s Cube is replaced with an LED display screen and these faces are bent into a sphere, a hexahedral LED spherical screen is obtained.
The advantage of this screen is that the pixels are evenly distributed, and the display effect is as clear as that of an ordinary flat LED screen. In addition, because it is composed of six identical faces, it is relatively simple to make. Each face is composed of four small boxes, each of which contains 16 circuit boards and LED lights are welded. Finally, these small boxes are combined together to form a complete spherical screen.
2. Working Principle of Spherical LED Display
The operation of spherical LED display mainly relies on the self-luminous technology of LED (light-emitting diode). By finely adjusting the brightness and color changes of LED lamp beads, a variety of images and video content can be displayed on the screen.
Due to its unique spherical structure, spherical LED display screens require special processing of flat image sources in order to map them to a three-dimensional spherical surface. This usually requires splitting the image into multiple parts and deforming and mapping them according to the geometric characteristics of the spherical surface to ensure that the image can be accurately displayed on the spherical screen.
This type of display screen is usually composed of multiple LED modules or unit boards to form a complete spherical surface. Each LED module or unit board contains a certain number of LED lamp beads and is independently controlled by the control system to achieve a consistent display effect on the entire screen.
The control system is the core component of the entire display screen. It is responsible for receiving image source signals, performing image processing and mapping, and then transmitting the processed signals to each LED module or unit board. This system also needs to synchronize the control of each module to ensure that the image can be presented smoothly on the spherical screen.
In addition to conventional image and video displays, the spherical LED display can also achieve special effects such as dynamic gradient, text scrolling, etc. These effects can be achieved through programming and control systems, bringing richer visual experience to the audience.
3. Differences Between Spherical LED Display and Traditional LED Display
1). Shape and Design
Traditional LED Display: Generally, it is a flat fixed rectangular or square design. This design is very suitable for applications in common scenarios such as supermarkets, bus stations and retail stores.
Spherical LED Display: Breaking the plane limitation, it adopts a three-dimensional spherical structure. Such a novel design can not only greatly attract the eye, but also provide a wider viewing angle and immersive visual experience.
2). Display Range and Viewing Angle
Traditional LED Display: Due to its flat design, viewers must stand at a specific angle to fully see the image on the screen. When viewing from the side of the screen, part of the image may be missed.
Spherical LED Display: The spherical design allows viewers to enjoy the full image no matter where they are. Such a 360-degree display ensures that every viewer can get the ideal viewing effect.
3). Production Difficulty and Cost
Traditional LED Display: Despite the continuous improvement of manufacturing technology, the production and installation process of this type of display is generally simple, so the cost is low and suitable for a wide range of application needs.
Spherical LED Display: The production of this type of display requires more complex design, advanced manufacturing technology and more sophisticated installation procedures. Due to its unique customization, the cost is often higher and suitable for specific high-end markets.
4). Application Field and Flexibility
Traditional LED Display: Due to its universality, it is widely used in various occasions such as advertising, sports and entertainment, and can be seen in commercial and home environments.
Spherical LED Display: With its unique design and excellent display effect, it is more suitable for innovative and high-end applications, such as planetariums, art exhibitions and luxury commercial displays. These places usually require special visual appeal, and spherical LED displays can meet such needs.
4. Advantages of Spherical LED Display
All-Round Vision
Spherical LED display provides 360-degree surround display, and the audience can enjoy clear and vivid images and videos no matter where they are. This panoramic display method creates an immersive visual experience for the audience.
Imagine standing in the center of a huge sphere, no matter which direction you look, you can see a clear picture in front of you. This is the unique charm of spherical LED display, as if you are in an enveloping visual feast.
Excellent Flexibility
The spherical LED display can be customized according to specific occasions and needs. Whether it is screen size, resolution or brightness, it can be adjusted according to your requirements. This flexibility makes it suitable for a variety of environments and uses.
Seamless Splicing
Traditional display screens often have gaps and color differences when splicing multiple screens, while the spherical LED display screen achieves seamless connection of the screen through special splicing technology, forming a complete sphere and providing a more perfect visual effect.
Reduced Cost Lamp Bead Design
Although the spherical LED display screen is full of technology, its cost is not high. By adopting uniform spot sampling technology, while ensuring the display quality, the number of LED lamp beads used is reduced, thereby reducing production costs, allowing you to enjoy high-quality display performance at a more economical price.
Energy Saving and Environmental Protection
As a highly efficient and energy-saving light source, LED lamp beads consume less energy and have a longer lifespan than traditional display technology. In addition, LED does not contain harmful substances and has outstanding environmental performance, which means that the use of spherical LED displays can not only bring excellent visual effects, but also contribute to environmental protection.
Wide Range of Application Scenarios
The spherical LED display can shine in museums, planetariums, stadiums and other occasions. Whether it is displaying works of art, playing astronomical videos or broadcasting sports events, it can present excellent visual effects. In addition, its unique appearance and display effect also make it an ideal choice for various activities and performances.
