Using high-definition LED special-shaped screen to play video content, viewers within a radius of tens of meters can enjoy high-definition and high-quality high-definition images. Wide playback angles enhance the comfort of viewing images. It is a visual communication medium suitable for exhibitors and public facilities. The high-definition LED spherical screen has a 360° full viewing angle, playing videos in all directions, and you can feel good visual effects at any angle without the problem of flat viewing angles. At the same time, it can also directly map spherical objects such as the earth, football, etc. to the high-definition LED special-shaped screen according to needs, which makes people feel vivid and is widely used in museums, science and technology museums, and exhibition halls. There are currently three types of LED spherical screens on the market: 1. Triangular LED spherical screen: A spherical screen composed of a flat triangular PCB, commonly known as a football screen, which overcomes the shortcomings of the watermelon skin ball screen that the north and south poles cannot play images, and the screen utilization rate is large. improve. The disadvantage is that there are many types of PCBs, and the pixel pitch is restricted by the honeycomb arrangement, and the dot pitch cannot be less than 8.5mm. Therefore, software writing is also more troublesome, and the entry technology threshold is too high. 2. Watermelon rind LED spherical screen: The earliest ball screen on the market, commonly known as the watermelon rind ball screen, is composed of watermelon skin-like PCBs. Its advantage is that it is convenient to make, and there are fewer types of PCBs, lower entry barriers, and more popularization. Fast, the disadvantage is that the north and south poles (or north of 45° north latitude and south of 45° south latitude) cannot play images, so the picture utilization is too low. 3. Six-sided panoramic LED spherical screen: It is a spherical screen composed of a quadrilateral PCB that has only appeared recently, and is called a six-sided spherical screen. Its PCB board types are also less than football screens. The entry barrier is relatively low, and the dots are closer to the flat high-definition LED special-shaped screen. The minimum dot pitch is similar to the flat high-definition LED special-shaped screen, with little or no restriction, so the effect is much better than the spherical screen composed of triangular PCB. In terms of physical size, the entire LED spherical screen is composed of 24 spherical surfaces of the same size. The LED spherical screen can be put into the flight case, which is very convenient for disassembly and assembly, which is convenient for renters to use. In playback, the LED spherical screen divides a spherical screen into 6 identical screens, namely up, down, left, right, front, and back; of course, different video sources can be played individually or in combination through software. Therefore, the playback effect of the LED spherical screen is much better than that of the watermelon peel ball screen and the football screen. The high-definition LED special-shaped screen is a special-shaped LED display based on the LED display. It is different from the rectangular and flat plate-like appearance of the conventional LED display. It has different shapes, including arcs, curved surfaces, and tetragonal hexahedrons. , Letters and other irregular shapes. According to the shape, the LED special-shaped screens are roughly divided into the following categories: (1) The display surface of the LED display screen is composed of several display strip molds, and this type of display screen has a large dot pitch, high permeability and contrast. Lower. (2) The display surface of the irregular-shaped LED display is an irregular plane, such as a circle, a triangle, or a completely irregular plane. (3) Curved led display: The display surface of the led display is a three-dimensional curved surface, such as a spherical screen, a polyhedron screen, and a sky screen. (4) Arc-shaped led display screen: The display surface of the led display screen is a part of a cylindrical surface, and its expanded view is a rectangle. LED special-shaped screens are widely used in led curved screens and led spherical screens. High-definition LED special-shaped screens are in a stage of rapid development and growth. Nowadays, the high-definition LED special-shaped screen market is showing great changes, except for traditional information displays. In addition to other functions, the requirements on the appearance are also further improved, so that it can better adapt to the overall structure and use requirements of the environment, resulting in LED special-shaped display screens.
