TAIPEI, Taiwan - AMOLED self-illuminating display panels have been pushed to the limit of thinness and have become the top choice for high-end display panels on mobile devices. However, this technology is now faced with a new contender. Chunghwa Picture Tubes Ltd. (CPT) is currently developing a type of self-illuminating display panel technology called Quantum Dot Light Emitting Diodes (QLED) which uses a print coating method.

At this year's Touch Taiwan exhibition, CPT showcased their new QLED technology, which is a type of material using conductivity to produce glowing luminescence, and this technology can be used in soft and transparent substrates.

CPT's QLED technology is a printing methodology product which can illuminate quantum dot material coating on substrates using a high-precision inkjet printer. According to CPT's data, QLED has purer colors, longer lifespans, and better energy efficiency and stability. In addition, the production costs are lower.

Jan-Tian Lian Ph.D., Manager of the Material Technology Division of Advanced Technology Center of CPT explained that in contrast to OLED, QLED technology uses inorganic materials; therefore, it has higher functionality. To date, QLED has successfully been used to produce light in CPT's laboratories, and they should be able to mass produce it in two year's time.

He also pointed out that the obstacles to manufacturing QLED have already been overcome. At this point, the major challenge is the research and development of quantum dot materials. Consequently, CPT is continuing to conduct R&D on quantum dot materials.
