The patent pending invention greatly simplifies the manufacturing process used in current 3D displays by replacing the use of optical lenses such as lenticular sheets etc. with a light modulator comprising FLC digitally controlling the light direction in synchronization with the time multiplexed operation of ECHO displays at very high speeds. This configuration enables unique views emitted at high speeds with high angular precision over a wide viewing zone. So far, the configuration has been successfully tested at speeds well beyond what is needed to show high quality autostereoscopic 3D for 5 or more people with individual perspective for each user. The technology thereby eliminates a well-known trade-off in current 3D and dual view 2D displays: either spatial multiplexing for many users with reduced resolution or time division multiplexing allowing only two individual views.
The Company’s development and commercialization plans now include three paths and opportunities:
- the first being the ECHO LCD technology that was announced in a press release on
30 January 2023 , and - the second being the ECHO microLED or OLED based FLC display technology exhibited at Display Week, and
- the third being the “pure” OLED ECHO path for which the successful completion of the integration license package was announced on
1 April 2022 and a notice of allowance confirming the patentability was announced on31 January 2023 .
The fastest path for the Company, or a licensee of the ECHO technology, to mass-produce a 3D ECHO-display is to use the ECHO LCD technology, as it is produced with existing display panels. A public demonstration of a 17-inch full-HD display based on the ECHO LCD technology that can show the same 3D-content for multiple viewers and different 2D images for two simultaneous viewers (dual-view) is still planned to take place during the second half of 2023. The LCD version has many use-cases, for instance in vehicles, CAD presentations, surgical displays, virtual meetings, virtual receptionists, gaming, and the like in display sizes up to 110-inches. The Company continues its presentations of the first version at its lab in
The Company also continues its development of the “pure” OLED version of ECHO in collaboration with the
While the microLED technology has the potential to beat OLED in most metrics, including power consumption, lifetime, brightness, temperature range and response time, the microLED technology in general is a next generation technology that requires further maturation before it will be able to compete with OLED on price. In the shorter timeframe, LCD is expected to sell at greater volumes, and combined with ongoing upgrading of the technology, the LCD market is expected to account for the largest portion of the display market for many years to come.
With different technology paths lined up for displays capable of creating social and immersive 3D experiences, the Company opens its opportunities for use-cases for both early and late adaptors, and

He continues: “The display is merely 2-inches diagonally, but it is nothing less than a break-through technology that will eliminate the optics and introduce a completely new and revolutionary way of displaying live pictures with extreme speed FLC, thus enabling multiple viewing and 3D capabilities without any loss of resolution. I must say that I am overly excited about our accomplishment with the microLED proof-of-concept. The completion of the 2-inch display would not have been possible without the continued support of our investors and the recent InnoBooster contributions by Innovation Fund Denmark. We have plans to design and build 85-inch versions of this display with collaboration partners and licensees, and we look forward to meeting the global display industry during Display Week and fuse further commercial interest in the Company’s intellectual property rights in the domain of revolutionary 3D and holographic display technologies.”
