“…This is shown in Figure 1. A stop-gap measure is to transfer blue µLED from one wafer then use red and green quantum dots on two of the blue µLEDs to make full color displays [3,4,[8][9][10][11]. It remains to be seen if green QDs deposited on blue µLEDs will have sufficient lifetime under high luminance conditions that are driven by the small size of µLEDs compared to the pixel size.…”

Micro Light Emitting Diode (µLED) emissive displays have emerged as promising solution for low power mobile displays. Here, we propose a new structurefor red (for example) light emitter composed of a blue µLED, a quantum dot (QD) film, a passivation film, and a metamirror that is reflective to blue light and is transmissive to red light. We present a design and analysis of such structure based on analytical modeling. The proposed architecture enables power efficient µLED displays.

Inkjet‐Printed, Flexible Full‐Color Photoluminescence‐Type Color Filters for Displays

et al. 2022

View full text Add to dashboard Cite

Photoluminescence‐type color filters (PLCFs) are supposed to offer vivid colors and higher power efficiency for modern displays by removing absorption losses of the conventional color filters (CFs). Inkjet printing (IJP) is a versatile and low‐cost method to pattern color converters. But uniformity of the patterns is a big concern. Poor photoluminescence stability is also problematic, especially for the perovskite nanoparticles (PNPs) and quantum color converters. Herein, a porous polymer film (PF) is deployed as a template for IJP. The capillary effect of sub‐micron pores in the PF modifies the rheological process of ink spreading that eliminates the coffee‐ring effect and simultaneously provides photoluminescence (PL) stability. A high‐quality green PNP, and red quantum rod (QR) based CF array onto the PF is successfully printed. A liquid crystal display (LCD) deploying this full‐color PF CFs is demonstrated. Color gamut of the device could reach 96.9% of BT2020. The PF CFs show good PL stability for more than 218 days. Furthermore, the fabricated PF CFs possess great flexibility, and any chromaticity and brightness change after 10 000 times of folding were not observed. Thus, the proposed CF using the PF is highly suitable for flexible display and photonics components.
