BOE developing small panel quantum dot display
As part of the Chinese Ministry of Science & Technology R&D program, BOE (000725.CH) is developing a small panel (5”) quantum dot display. The device, which is said to be produced using an ink-jet printing process, has no backlight, indicating that the device is generating light directly from the quantum dots. While there is little information about the project, as it is only one of 863 programs sponsored by the ministry, and the most recent ministry newsletter is from 2012, we expect the device is a preliminary prototype, and far from near commercial production.
As we have noted in the past, the current use of quantum dots is in films that enhance the color accuracy of LED backlight devices, with the next timeline inflection point being the use of the materials directly as LED phosphors, with the final goal, a self-emitting device, such as the one mentioned above. The development of such a device, and its eventual commercialization remains a few years away according to our contacts in the industry, but we do expect to see similar articles, demos, and IP toward that goal, especially from Chinese display participants, as the playing field in QDs is far more level than in OLED, where South Korean producers dominate the space. While we expect the BOE project is a very early stage device, where there’s a will, there’s a way…
