INNOVISION Has Made Another Breakthrough in VSP Technology and Launched Mass-produced Single-chip Full-color Micro-LED Display Chips
2024-08-21 10:24
INNOVISION recently launched mass-produced single-chip full-color XGA Micro-LED display chips, which are based on INNOVISION WLVSP™ technology platform (wafer level vertically stacked pixels, abbreviated as VSP) and integrated by stacking RGB compounds and silicon-based CMOS driver backplanes in the vertical direction.
The single-chip full-color micro-display chip launched this time is based on INNOVISION's latest VSP technology, which has achieved a qualitative leap in display uniformity and brightness.
The new VSP single-chip full-color chip has a peak brightness of over 500,000 nits, making it the Micro-LED RGB single-chip full-color micro-display chip with the highest brightness and best display effect currently known.

In addition to pursuing the improvement of chip-level technical indicators, INNOVISION Technology pays more attention to the improvement of chip application system indicators. Especially in the case of power consumption and restricted heat dissipation of wearable devices, more focus shall be put on improving the efficiency of low-power application systems. By improving the optical coupling efficiency through optical collimation, INNOVISION VSP series products can achieve a more than two-fold increase in optical and waveguide brightness compared to the existing solutions.
Single-chip full-color chip is the ultimate challenge for Micro-LED displays and the direction where major chip manufacturers in the industry have invested heavily in R&D. At present, both prism combined light schemes and quantum dot schemes have significant limitations. The launch of INNOVISION's VSP full-color micro-display chips has opened a new chapter in the Micro-LED display industry, which will accelerate the commercialization process of global Micro-LED display colorization.
It is expected that INNOVISION will mass produce single-chip full-color micro display chips in 2025. We welcome upstream and downstream partners to jointly promote the large-scale application of Micro-LED display chips in terminals.
