The news showed that TCL CSOT launched the 17” IGZO inkjet printed OLED folding display globally at the “Endeavor New Era” theme achievement exhibition on September 27th.
According to reports, the product is jointly developed by TCL CSOT and Guangdong Juhua Printing and Display Technology Co., LTD. (hereinafter referred to as “Juhua”). It adopts autonomous light-emitting inkjet printing OLED technology, with vivid colors and a new Oxide compensation circuit technology, and is compatible with NoteBook, Pad and Monitor.
In addition, the screen supports intelligent split screen function to realize multi-task cooperation with the interface. That’s to say, one screen can be used as a notebook display, and the other screen can be used as a display keyboard or note recording at the same time.
Through the enhanced design of the folding screen and the selection of module materials, TCL CSOT has made the folding radius of the folding screen reach 3-5mm, and the dynamic bending life is up to 100,000-200,000 times. Even if it is opened and closed 100 times a day, it can be used for at least 5 years.
It is known that the 17-inch IGZO ink-jet printing OLED folding display adopts the flexible inkjet printing OLED technology jointly developed by TCL CSOT and Guangdong Juhua. Juhua has opened the printing OLED/QLED process, and focused on the three directions of high resolution, flexible winding and printed quantum dot display, which has laid a solid technical foundation for the mass production of printing and flexible display technology.
TCL CSOT said that thanks to Juhua’s development of printed OLED device structure, inkjet printing technology, printing drying film technology, flexible film packaging technology and flexible LLO technology, the 17-inch IGZO IJP OLED folding display has successfully achieved technical breakthroughs. It solves most of the problems in inkjet printing OLED technology and lays a foundation for the mass production of large-size printing windable flexible OLED display technology.
Highlights includes:
- Lower production cost: TCL CSOT uses printing method to prepare OLED flexible devices, which can make the material utilization rate reach more than 85%. The production cost of printing method is about 20% lower than that of evaporation method.
- Better film forming process: TCL CSOT optimized the film forming process of each film layer by reducing the Q-Time, which effectively improved the film forming uniformity in plane and pixel.
- Technical support for mass production: TCL CSOT’s perfect LLO technology and 4.5/5.5 generation line have provided technical reserve and mass production guarantee for the operation of mass production line. It is said that after mass production, it will bring drastic changes to the whole display panel industry.
