Recently, JOLED, a Japanese panel supplier, announced the establishment of a JOLED beauty institution in Neng Mei, Ishikawa County, Japan, and a JDI flag plant under another Japanese panel to measure the OLED panel using printed technology. The JDI factory is the 5.5 generation of panel lines shut down last year. After the JOLED takes over this year, it will be transformed into a printed OLED production line with 20 thousand production capacity per month.——OLED
JOLED's printing OLED process is a process for spraying liquid luminescent materials like printer inks on substrates. As early as the end of 2017, JOLED had produced products using printed OLED panels. This is a 21.6 inch panel with a resolution of 3840x2160 (4K, 204 PPI) and a brightness of 350nits. The thickness of the entire panel is only 1.3 millimeters, and the weight is only 500 grams. It is reported that this screen has been contracted by SONY and will take the lead in the medical field.——OLED
At present, the OLED panel manufacturers, including Samsung and LG Display, are using "steam plating" technology, that is, to vaporize red, green, blue and other luminescent materials on the substrate in the vacuum state. Severe vacuum conditions and good quality problems make the price of OLED TV at present high.——OLED
Because the printing technology has no need for the vacuum environment, and because of its simplified process, such as without the need of color filter, ink jet printing to reduce the cost of depreciation and low electricity and water, the initial investment burden of the enterprise is small, the material loss is less, and the relative good rate is high, because this can lower the cost than the steam plating process. The production of OLED panels is said to be more than 30% lower than the cost of evaporation.——OLED
Of course, at present, there are still some technical difficulties in OLED panel printing process. As the basic of the printing process, the water vapor pollution resistance and oxidation resistance of the liquid OLED monomer have always been the focus of the research. How to make the OLED monomer into the nanoparticles with water and oxygen barrier encapsulation, and have good ink dispersion performance and not damage the water and oxygen barrier encapsulation in the process of printing, is the present study. The ultimate goal.——OLED
Once this OLED monomer material technology has made a breakthrough, the printing type OLED panel process will become the mainstream of the industry. Because of its technological progress, the significant reduction in cost will enable the OLED to usher in a new outbreak period, and may be able to compete fully with the LED product!——OLED
2018 already half, in the sluggish color TV market at the end of 2017, OLED TV as a new army's reverse trend, although the market share is still relatively small, but when the printing technology is mature, the cost of OLED TV is further explored, the rate of good product is further improved, and it is believed that OLED TV will also go into common people like today's LED TV. Home.——OLED
