55-2:Invited Paper: ILED Displays: Next Generation Display Technology

Abstract

The emergence of ILED Displays (also termed MicroLED Display) has the potential to be a true 4th Gen flat display technology by superseding Plasma, LCD and OLED technologies. They offer significant increase in power efficiency, brightness with reduced cost. The use of inorganic LEDs largely removes the challenge of lifetime and sealing which, until recently, has curtailed the wide adoption of OLED display. While ILED Display technology offers a range of benefits, there remain a number of issues to be addressed before this new display technology can achieve market acceptance. InfiniLED introduces the technology, discusses some of the performance characteristics and presents its practical approach to commercializing this technology.

Micro Light‐Emitting Diodes for Display and Flexible Biomedical Applications

“…In addition, µLEDs have great potentials to produce high‐quality images because of their fast response time (≈5 × 10 4 times shorter than that of OLEDs), high color reproduction rate of 140%, and wide view angle . At identical pixel number and light intensity, the power efficiency of a µLED display was 77 and 4 times higher than those of LCD and OLED displays, respectively . Based on these excellent characteristics, µLED is considered as a promising light source for future displays, like ultrathin UHD TVs, flexible and biomedical applications by overcoming the limitations of previously displays.…”

“…To meet the display performance targets for efficiency and brightness it is necessary to achieve a high external quantum efficiency (EQE) which depends on both efficient light extraction [4] as well as an internal quantum efficiency (IQE) of at least 25% within the micro-LED. Figure 3 shows simulation results for effective carrier sheet concentration and IQE for different LED sizes and sidewall recombination rates.…”

“…Micro-LED arrays and displays have been demonstrated in prototype form with both rigid and flexible backplanes using different mass transfer approaches to spread micro-LEDs onto the display backplane to form emissive red, green, and blue (RGB) pixels [1][2][3][4]. Micro-LED arrays with <1" diagonal and up to 6,000 pixels per inch (PPI) [5,6] have been hybridized to CMOS backplanes for micro-display applications such as augmented reality and compact projection.…”
