Abstract

Emissive displays have long been considered as the ideal displays due to its emissive nature which brings strengths in key areas such as deep black level, fast response time and wide viewing angles. The first successful flat panel emissive display product was flat panel plasma display. However, the plasma display had eventually been completely driven out of market by non-emissive LCD displays due to plasma display’s weakness in low peak brightness, susceptible to screen burn-in, visible flickering effect, not suitable for portable devices and high power consumptions. As a new generation of emissive displays, OLED displays have recently become popular due to its improved performance, suitability for portable devices and compatibility with super-slim design. However, there are still fundamental limitations with the current OLED displays.

This is especially true for large size OLED which employ WOLED technology. Key limitations of current OLED displays are relatively low peak brightness, limited lifetime, high cost and high power consumptions (for WOLED). The inorganic nature, narrow FWHM and continuously tunable in peak wavelengths make quantum dot an ideal light source for displays. This paper will discuss emissive implementations that allow quantum dot to overcome the weakness of existing OLED displays. We believe such emissive displays enabled by quantum dot are the ultimate dream displays that people are seeking.
