As the public's creative demand for LED displays has increased, traditional LED displays have been unable to meet everyone's needs, so major LED display manufacturers have begun to develop LED creative special-shaped screens. LED spherical screen is one of the very popular ones. product. So do you know what are the common types of LED spherical screens? Today, follow LCF Xiaobian to find out.

一、the basic principle of LED spherical screen

The led spherical screen is composed of a core control module, a rotating display module, a wireless module, a font library module, a motor drive module, and a power supply. The fan blade is designed to be circular, and there is a circle of LED lamp beads on the fan blade. The LED light-emitting color is single-color or multi-color. When the fan blade rotates around the central axis, a spherical surface will be generated, and all the spherical surfaces are LED, with the font software, when the fan blade goes to the corresponding position, the corresponding point is lit, so that the display content of a spherical surface can be controlled.


二、the introduction of the types of led spherical screen

(1) Watermelon-shaped led spherical screen

This one is an early led spherical screen on the market. It is composed of a PCB similar to the shape of a watermelon rind. It is characterized by a very intuitive structure and requires fewer types of PCBs. Images cannot be played properly at the north and south poles. Therefore, the screen usage rate of this product is relatively low, and the image will be deformed to a certain extent, because the pixel points of all image sources are now arranged in rows and columns, but the pixels on the north and south poles of the watermelon peel led spherical screen The dots are arranged not in rows and columns but in circles, so it is difficult to display.

(2) Football-shaped led spherical screen

The main component of this LED spherical screen is a triangular PCB board, which solves the shortcoming that the watermelon peel led spherical screen cannot play images at the north and south poles, so its screen usage rate has been improved a lot, but there are still some shortcomings, that is, the PCB There are many types of LEDs, and the pixel points are arranged in a honeycomb shape, which limits the pixel spacing. This kind of LED spherical screen generally needs to be made larger, and the software writing is also very troublesome.

(3) Six-sided led spherical screen

This is a relatively new product, a led spherical screen composed of a quadrilateral PCB board. The six-sided led spherical screen has fewer types of PCB boards, and the pixel distribution is closer to the conventional led display. Therefore, as long as the content that can be played on the conventional display can basically be directly applied to the six-sided led spherical screen, the same as the above Compared with the two led spherical screens, the display effect will be much better.

The above are the main three types and design structures of full-color LED spherical screens. After years of unremitting efforts and continuous process improvement, Liancheng engineers have applied conventional display modules to about 100 special-shaped displays. In addition to the display effect and protection, it also greatly improves the service life of the product and effectively reduces the overall production cost.

3. Advantages of LED spherical display

(1)The full-color spherical LED display adopts surface-mounted three-in-one LED lights, spherical structure design, and the display unit can be assembled into an inner arc display surface shape, an outer arc display surface shape, and an inner circular display surface shape after special treatment. S display surface, spherical and other special-shaped screens have display effects that cannot be achieved by ordinary conventional display screens; spherical stereo playback, 360° viewing without dead ends, personalized design, resulting in shocking visual impact.

(2)Seamless splicing: The trapezoidal circuit design can achieve seamless splicing.

(3)Uniform snapshot: Support uniform snapshot technology, the display screen is not distorted.

(4)Flexible control: synchronous and asynchronous compatible, supports both offline and online modes.

(5) Good heat dissipation: aluminum structural heat dissipation solution is adopted.

(6) Easy installation: as a complete system, it supports floor installation, hoisting, embedded installation, etc.

(7)Easy to maintain: support pre-maintenance and post-maintenance.

(8)High resolution and high refresh rate: The resolution and refresh rate of the display are the other two performance indicators of the display. The gray level can be 10-16bit, and the full-color system can support 1024×768 screen resolution and screen refresh rate up to 300Hz at the same time, far exceeding the performance indicators of traditional solutions, making the display screen stable and flicker-free , no trailing.

The above is the introduction of the three types of LED spherical screens.
