LED display 3D is a technology that uses LED display to achieve 3D visual effects. The principle of LED display 3D is to realize simultaneous light emission of multiple pixels on the LED display, and to achieve 3D visual effects by adjusting the light-emitting angle and color of the pixels. LED display 3D technology can be widely used in stage performances, exhibitions, commercial advertisements and other fields, and can bring more realistic visual effects. The realization of LED display 3D technology requires the support of multiple key technologies, including LED display design, optical design, image processing and other technologies. In the design of LED display screens, it is necessary to select appropriate LED devices and packaging methods to ensure that parameters such as brightness and color reproduction of the display screen meet the requirements. In the optical design, factors such as the angle of LED light emission and the distance between the LED and the observer need to be considered to ensure the best 3D effect of the LED display. In image processing, image correction, interpolation, rendering and other processing are required to achieve realistic 3D effects. The realization of LED display 3D technology needs to comprehensively consider the performance of LED display, optical design, image processing and other aspects, and needs continuous innovation and improvement in technology and technology to meet the market demand for LED display 3D.
