Problems solved by technology

[0003] The traditional LED display screen is spliced ​​by multiple LED display units. The PCB circuit board used is rigid and uncurlable, resulting in the LED display screen being rigid and uncurlable. Therefore, the LED display screen is heavy and bulky. There are few shapes and types, which brings great limitations to its transportation, installation and application

Abstract

The invention provides a coiled-type LED display screen, which comprises a PCB board and LED lattice units welded on the circuit board, wherein the PCB board is a flexible circuit board; and the LED lattice units are patch LED lattice units. The coiled-type LED display screen has the following advantages: 1, the product can be light, small and thin; 2, the product can be freely bent, folded and coiled, and can move and stretch in a three dimensional space at random; and 3, the product can be cut into any size according to requirements.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a curlable LED display screen. Background technique [0002] LED (Light Emitting Diode, light-emitting diode) display is a large-scale display system integrating microelectronics technology, computer technology, and information processing. It has become the most widely used display system in the world due to its unique advantages such as super large screen, super vision, and flexible and changeable display methods. It is an epoch-making product of information dissemination facilities. According to its light emission wavelength, it can be roughly divided into visible light LED and infrared LED. Visible light LEDs are widely used in automobiles and communication new products due to their characteristics such as low power consumption, long life, low heat generation, monochromatic light emission, fast response rate, good impact resistance, and small size. products, new information products...
