In recent years, China and other countries have invested heavily in the research and manufacturing capacity of display technology. Meanwhile, different display technology scenarios, ranging from traditional LCD (liquid crystal display) to rapidly expanding OLED (organic light-emitting diode) and emerging QLED (quantum-dot light-emitting diode), are competing for market dominance. Amidst the trivium strife, OLED, backed by technology leader Apple's decision to use OLED for its iPhone X, seems to have a better position, yet QLED, despite still having technological obstacles to overcome, has displayed potential advantage in color quality, lower production costs and longer life. Which technology will win the heated competition? How have Chinese manufacturers and research institutes been prepared for display technology development? What policies should be enacted to encourage China's innovation and promote its international competitiveness? At an online forum organized by National Science Review, its associate editor-in-chief, Dongyuan Zhao, asked four leading experts and scientists in China.
