7.56” Transparent Micro-LED
The world’s first Micro-LED display with transparency more than 70% and small pixel pitch
Tianma Microelectronics Co., Ltd. (Tianma), a leading global manufacturer of flat panel displays, will be constructing a full-process test line for Micro-LED based products, including the mass transfer process to display module in Xiamen, Fujian, China.
Project overview
- Name: Tianma New Display Technology Research Institute
- Location: Xiamen, Fujian, China
- Total Investment: 1.1 Billion RMB (160 M$)
- Construction Content: Micro-LED experimental platform, focusing on research for the mass transfer related technologies based on TFT substrate, including large-scale inspection, large-scale bonding, large-scale repair, packaging, and module manufacturing processes.
Technology
Micro-LED display technology is a pixel array display composed of LED chips below 50 micrometers. The LED chips are driven by an active driver array. Compared with the current mainstream display technology, direct emitting LEDs have advantages of higher brightness, high resolution, high contrast, wide color gamut, high reliability, low power consumption, high operating temperature and long lifetime.
Transparency:
Due to the small LED size of less than 50 micrometers – which is below the resolution of the human eye – transparent displays can be made while the LED chip itself remains invisible. The 7.56” Transparent Micro-LED display shown at the beginning is one of the first prototypes.
Flexibility:
Micro-LEDs can be put on flexible substrate, allowing to adopt the display itself to curved surfaces. This is shown in the example below.

The world’s leading internal folding radius: R=5 mm
Seamless splicing:
As the LED chips can be put on the driver substrate up to the border line, different displays can be spliced together like tiles forming a larger display area while the connection between them is (almost) invisible. Display areas from small to very large can be made, providing great potential for numerous applications. Micro-LED is considered as the next generation display technology in the industry with promising prospects for the future. In below picture shown is the 5.04″ seamless splicing Micro-LED display.

Market
According to market forecasts, the Micro-LED market has huge potential and is expected to achieve rapid growth in the near future. Omdia expects annual global shipments of Micro-LED displays to soar to nearly 15.5 million units by 2028.
