JOLED has announced they have developed the world's first 21.6-inch 4K (3,840 RGB × 2, 160 for a total resolution of 8,290,000 pixels) high-definition OLED panel using an RGB printing system.
In addition to adopting the "RGB printing method" of painting all the OLED materials of RGB by printing, JOLED have adopting equipment technology that can uniformly coat large areas substrates all at once. The company did not specify any specific deposition or coating technologies. In addition, it adopts its own "top emission structure" with high light extraction efficiency, it is the world's first 21.6-inch RGB printing system, has 4K high-definition screen and excellent colour reproducibility and wide viewing angle We will promote the commercialisation of OLED panels that will be realised. According to JOLED OLED panels have high image quality characteristics unique to them being self-emitting - for instance high contrast, faithful colour fidelity to original and fast response. Furthermore, since it has advantages such as thinness, light weight, and low power consumption compatibility, it is expected to be used as a next-generation display that creates new applications in a wide range of fields, such as medical use, game monitors, and automotive applications, in the medium-sized panel market. Since taking over as Panasonic Corporation and Sony Corporation's OLED panel technology and since its establishment in January 2015, JOLED have been conducting R & D and verification of the manufacturing of OLED panels by printing method. In the future, the company plans accelerate technological innovation and promote product development leading to "creation of customer value". Main Specifications of Developed Product
