BRIDGEWATER, N.J., April 20, 2019 /PRNewswire-PRWeb/ -- VerLASE
Technologies announced today that it is developing unique
technologies for massively parallel assembly of microLED dies or
films, the central challenge in microLED display manufacturing
today standing in the way of enabling wide-spread adoption of
microLED technology. Many observers point to the inherent
advantages of microLEDs such as brightness, efficiency, robustness,
and a vision of modular panels that could be tiled into displays of
any size. While a superior technology in theory which, for example,
overcomes the many problems surrounding OLED displays, microLED
displays have been bedeviled by practical manufacturing aspects.
Among these, perfectly assembling the microLED subpixels, which can
be as small as 10 microns or even smaller, in a commercially viable
way on a switching backplane remains a huge, unsolved problem.
Several companies, including a few start-ups, have shown various
approaches to solving this problem at trade shows and conferences,
however, the proposed methods appear too slow to be cost effective
and generally offer no apparent way of repair and replace, since
displays must be perfect with no misplaced pixels. The microLED
display prototypes shown to date also tend to have lower
resolutions (PPI) than might be needed today, for example, for a
typical smartphone display or 8K
display.
VerLASE is focused on practical methods that use well-proven
semiconductor and MEMs industry methods and existing tools in novel
ways to enable deterministic, massively parallel transfers of
microdie, yet with provisions that allow selective repair. The
methods use well developed techniques used daily in Ink-Jet
Printing but is not printing per se. Comprehensive patent filings
cover multiple variations of the Company's proprietary core LAAP™
process (Large Area Assembly Process). "In levering the Ink-Jet
industry, our solution offers a quick path for MicroLEDs to disrupt
the displays industry," said Ajay
Jain, Company CTO and inventor of the technology.
The Company is working on demonstrating the base principles of
its solution while in discussions with potential investors. VerLASE
had previously been focused on color conversion technology for
microLEDs and related applications, which remains a core capability
but decided to broaden the horizon given its novel solution to the
Mass-Transfer problem. It has 7 US Patents now issued covering
various aspects in color conversion, including some in Japan, Korea, and China, with others pending. It has now also
filed a suite of IP relating to its Mass-Transfer solution.
The patents that are issued encompass VerLASE's Chromover™
branded color conversion technology, which can efficiently
downconvert colors from inexpensive, widely available blue/violet
light sources such as LEDs, microLEDs, or laser diodes to any color
in the visible range for a wide variety of applications, to novel
materials used both passively as phosphors, and actively as the
electroluminescent layer in light engines of the near future.
The Company spun out of Versatilis LLC (http://www.versatls.com)
in 2013 with an investment by Wakley Limited, a Hong Kong based private investment group, and
operates with partners around the world. Founded by Versatilis'
principals George Powch (CEO) and
Ajay Jain (CTO), it focuses on
technology development for large markets of the near future
involving novel materials, structures and processes.
