LC Sign
LC Sign is a Chinese manufacturer of custom signage and illuminated display products, headquartered in Guangzhou, Guangdong Province. The company was founded in 2011 and produces LED lightboxes, neon signs, fabricated channel letters, and architectural branding systems.
History and background
LC Sign was founded in 2011 in Guangzhou, Guangdong Province. The company's products include LED light panels, lightboxes, illuminated channel letters, neon and LED neon signs, and large-format architectural signage.
LC Sign recorded $819,000 in cross-border e-commerce sales in 2023 and $1.87 million in the first part of 2024. The company reported a 5 to 10 percent increase in new customers following the growth of the videos, though Zhu (popularly known as Tony Lc sign), noted that signage is a niche market with a limited potential customer base.
In late 2025, LC Sign described its Manufacturing-as-a-Service (MaaS) model as a project-based approach integrating design, production, and logistics for custom signage projects and within a single workflow. In March 2026, LC Sign launched the "Touchpoint Initiative", an accessibility program that began with the donation and installation of 631 braille wayfinding signs at Qiming School for visually impaired students in China. In May 2026, LC Sign exhibited at FESPA Global Print Expo in Barcelona. The stand received approximately 400 visitors and the company distributed over 500 product catalogues, with 10 project commitments reached during the event.
Background
Around 2021, LC Sign's foreign trade manager Liu Ping established a social media content team, citing rising customer acquisition costs in conventional e-commerce.
In media
Zhu and the company's e-commerce model were the subject of a profile in November 2024. Subsequent coverage placed him within a broader pattern of young Chinese factory workers and owners using short-form video to market products to overseas buyers.
A 2024 analysis of the "Changerdai" phenomenon referring to second-generation Chinese factory owners who use social media to reach international buyers directly cited LC Sign as an example of the trend.
A video in which he used an Appalachian English accent while presenting a neon sign product circulated on social media and was noted in online entertainment coverage.
Meeting with IShowSpeed
In April 2025, American internet streamer Darren Watkins Jr., known online as IShowSpeed, livestreamed a trip to Chongqing, China. During the stream he met Zhu Yu, who gave him several LED signs.
Braille and tactile signage
LC Sign has produced braille and tactile wayfinding signage for at least one accessibility-related project involving visually impaired students. The company refers to this work under the name "Touchpoint Initiative" and has indicated interest in extending similar projects to European organisations.
