Description

Technical Field

[0001] The present application relates to the technical field of large-screen displays, and in particular to a bendable display screen. Background Art

[0002] As we all know, LED displays are now widely used in people's daily lives. Their advantages can be summarized as: high brightness, low operating voltage, low power consumption, large-scale design, long life, impact resistance, and stable performance. The development prospects of LED displays are extremely promising, with developments moving towards higher brightness, greater weather resistance, higher luminous density, higher luminous uniformity, reliability, and full color. LED displays are currently widely used in advertising in various outdoor venues, including stadiums, commercial applications, banks, securities companies, postal services, docks, shopping malls, stations, postal services, telecommunications, government agencies, surveillance systems, schools, restaurants, hotels, entertainment venues, and more.

[0003] Current large-screen LED displays typically focus on seamless splicing, ease of installation, and stability. This means they are essentially flat, with very few curved displays. The few existing curved displays are created by setting the angles of multiple flat LED light boxes together to create a curved effect. However, this curved effect isn't truly curved, as the LED light boxes still utilize traditional cabinet structures and lack a fundamentally curved design. Utility Model Content
