Live Report from CITE 2021: Mini/Micro LED Products Are a Major Focus of Exhibitions

The 9th annual China Information Technology Expo (CITE 2021) is being held at the Shenzhen Convention & Exhibition Center in Shenzhen, Guangdong Province. Duration of the trade show is from April 9 to 11. The main theme of the event is “Innovation-Driven High-Quality Development”. To effectively articulate this theme, the event organizers have divided the show floor into nine sections that include the main CITE exhibition, applications for new display technologies, and smart manufacturing. More than 1,500 companies are attending the event as exhibitors. Those companies that gather at the convention center to demonstrate their latest display technologies include TCL CSOT, Unilumin, Ledman, Konka, Skyworth, and Tianma.

Many display and LED manufacturers have come to CITE to show off products featuring Mini LED. TCL, Konka, and Skyworth have unveiled their latest TVs that incorporate Mini LED, while IVO and Tianma have also introduced automotive displays with Mini LED. As for CSOT, it is presenting a tablet and a notebook (laptop) computer that adopt Mini LED for backlight. The myriad of Mini LED offerings indicates that the development prospect is very bright for this technology.

Micro LED is another major highlight at CITE 2021. For instance, Tianma is showcasing a Micro LED automotive display. Micro LED has numerous technological advantages. It is a self-emissive display technology that has a long operational lifespan. Other benefits include the compatibility to work with transparent and flexible substrates as well as the ability to scale up infinitely in size. The range of applications for Micro LED is very wide. The technology can be used for small and midsize displays for cars and wearable devices. There are also opportunities in the market for large displays that are 100 inches or greater in size. All in all, Micro LED has an enormous development potential.


For CITE 2021, TCL has presented a complete set of AI-powered home appliances under the latest Linxi C12 series. The company has also debuted many unique technological solutions that have never been seen before.

Among the products being displayed at TCL’s exhibition, the X12 Starlight Mini LED Smart Screen is the world’s first TV that features a cutting-edge Mini LED backlight technology known as OD Zero. Regarding specifications, the backlight module contains 96,000 LED chips and has 1,920 local dimming zones. It therefore can achieve an ultra-high level of performance in terms of brightness (i.e., 2,000 nits) and contrast (i.e., 10,000,000:1).
