Description

Technical Field

[0001] The utility model relates to the technical field of LEDs, in particular to a holographic screen. Background Art

[0002] As technology advances, so too does display technology. Holographic screens, as an emerging display technology, offer significant differences in image presentation and viewing experience compared to traditional LED screens. Holographic screens offer a more natural visual experience, as they can display stereoscopic images without the need for special glasses. Furthermore, holographic screens typically offer higher image quality, allowing for finer details and richer color gradations, making them potentially applicable in a wide range of fields, including advertising, entertainment, and education.

[0003] In the related art, multiple groups of LED chips are arrayed on the light board, and each group of LED chips is configured with an independent IC. The multiple groups of LED chips are connected to each other and pulled to the outside. The external main control chip allocates the network address of the IC and controls it. The periphery of the LED chip is completely covered by a protective shell, and the main control chip is inside the protective shell. However, because each LED chip has an independent IC, once damage occurs, the protective shell, the main control chip, and the damaged LED chip need to be completely removed and replaced, and the network address needs to be reconfigured, making screen maintenance very difficult.
