China-based Visionox demonstrated many OLED displays and new technologies at Display Week 2023.
So first up, we have some rollable and foldable OLEDs. You can see some impressive looking such flexible OLEDs in the video above, and Visionox featured many such displays at their booth.
For the automotive market, the company showed a small flexible touch-enabled panel, in addition to a transparent display. These were shown on small car mockups, as you can see above.
Visionox also demonstrated several new technologies that aim to reduce the power consumption of the company's LTPS OLED panels - for example its EnV ALT technology, that can reduce the refresh rate of its OLED panels up to only 1 hz - which helps to conserve power (Visionox estimates this at 10% compared to standard LTPS). The company is also working on a technology that will enable different refresh rates at different parts of the screen - this can be useful in video conferences, for example, as the video requires a fast refresh but other parts of the screen do not change so often.
Another technology is the company's HLEMS panel, that offers a new light-extraction model to increase efficiency by over 10%, using a new structure and new materials.
Visionox also showed some extreme all-round narrow bezel panels - with bezels of 0.5 mm and 0.6 mm all around the panel, which required a new pixel circuit driving design.
Finally, Visionox demonstrates its ViP technology, the most interesting technology on show. ViP, or Visionox Intelligent Pixelization, replaces the commonly-used FMM deposition with photolithography-based pixel patterning, to enable higher aperture ratio - so that displays can be higher in density, or alternatively higher brightness and efficiency.
Visionox reports that when combined with its tandem-stack architecture, its ViP OLEDs enjoy a 6X increase in lifetime, or about 4X increase in brightness, compared to its standard FMM AMOLEDs. The technology has been in development since 2016, and the company is now developing mass production capabilities.
