Tianma has announced the successful full-process integration of its MicroLED production line, along with the unveiling of a proprietary PID (public information display) standard display module. According to the company, the new module is built on an LTPS-based glass backplane and employs Tianma’s proprietary all-laser mass transfer technology, enabling high-resolution, bezel-free displays of any size.
Tianma’s involvement with MicroLED technology began in 2017, with a stated focus on high pixel density (PPI), high brightness, and high transparency. The firm has introduced a number of MicroLED concepts over the past several years—including high-transparency, seamless-splicing, adjustable-transparency, ultra-low-reflection, and ultra-high-PPI displays—signaling ongoing research and development efforts in next-generation display applications.
The core of Tianma’s announcement centers on its all-laser mass transfer approach, sometimes referred to as laser-induced forward transfer (LIFT). During this process, individual MicroLED chips are released from a donor wafer via precisely targeted laser pulses, then bonded to a display backplane. The company reports that this non-contact, laser-driven method aims to improve throughput and accuracy when transferring millions of microscopic LED chips. An all-laser technique is also expected to mitigate some of the mechanical and alignment challenges encountered by more traditional pick-and-place methods.
Construction on the full-process MicroLED line began in 2022. Tianma worked with over 30 upstream and downstream partners in equipment and materials development, introducing custom-made mass transfer and bonding systems. The company indicates that these collaborative efforts underscore a shift in the display industry, where dedicated production lines and specialized equipment are essential to scaling MicroLED technology for commercial applications.
With the line now fully integrated, Tianma states that this move will enhance its competitiveness in new display technologies. According to Tianma, this achievement will also support China’s ongoing push toward localization and independent innovation in advanced display manufacturing.
Although further details on product availability and output capacity have yet to be disclosed, the firm maintains that the commercialization of MicroLED technology will accelerate in line with improvements in yield, efficiency, and equipment automation. By advancing its full-process MicroLED line and demonstrating a working module, Tianma aims to reinforce its position as a competitive player in higher-resolution, higher-brightness, and more transparent displays.
