The LED screen presents an inverted artistic image composed of pixels. Pixel is a fundamental concept in image processing, the smallest controllable element in an image, and the basic unit of digital images. By viewing LED images through a spherical lens, a wonderful refraction phenomenon can occur, which enables us to understand the application of pixels in digital technology.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Pixel is a fundamental concept in image processing, the smallest controllable element in an image, and the basic unit of digital images. The size and quantity of pixels determine the resolution and quality of an image. In digital image processing, pixels are widely used in various scenarios: in early home computer gaming devices, due to functional limitations, data storage and display technology, people had to complete the design of computer interfaces and game art under extreme conditions of low resolution and color limitations. At the same time, special techniques such as jitter and manual anti aliasing for pixel painting emerged under these conditions.
