On November 12, Visionox announced that they recently developed 604ppi (approximately 4.85inch) high resolution full color OLED panel through FMM (fine metal mask) using evaporation technology.
In 2014, Visionox developed 570ppi RGB AMOLED panel with newly developed pixel structure, Z-Type. This Z-Type arrangement had larger blue sub-pixel with green and red sub-pixels beside it. The new panel has resolution of 604ppi which is a 35ppi increase from the 2014 panel. With this new reveal, Visionox displayed their high resolution OLED technology improvement.
The 604ppi panel combined the self-developed pixel layout under proprietary intellectual property rights and co-developed Chinese FMM. The resolution is 2,560 × 1,440, manufactured using real RGB method and not pentile.
Chinese companies are developing their high resolution AMOLED panel technology at a fast pace. In August, EverDisplay presented 734ppi 6inch panel, and the technology difference with Korean panel companies is rapidly decreasing.
Visionox revealed that this OLED panel shows Visionox’s research development for high resolution OLED is continuing and aptly demonstrated the current results.
