65‐1: Invited Paper: Narrow Spectrum Deep Red Emitters for OLED Lighting and Display

Abstract

We report narrow lineshape phosphorescent emitters enabling high luminous efficacy deep red emission for automotive lighting applications. As a result of the narrow 43nm FWHM and high efficiency, we achieve 16cd/A LE and 55,000hr LT95 at 1,000nits with a 640nm peak and 625nm dominant wavelength in a bottom emission device.

“…Both emitters meet SAE and ECE requirements, but the deep red emitter (RD2) tailored for automotive lighting was required to meet the requested color and dominant wavelength. [5] Device performance for each emitter at nominal operating conditions is compared in Table 1, while CIEx, y at 0' degree and at different viewing angles are shown in Fig. 2 and Fig.…”

“…Moreover, the FWHM of Device-2 was almost 18 nm narrower than that of Device-1 as expected from the PL data, which is expected to lead to additional efficiency enhancement in a top-emission device. [7,11] Figure 1. The PL spectra of the red phosphorescent emitters DRD-I and DRD-II.…”

“…OLEDs are widely used in small to medium sized displays, such as mobile phones, tablets, laptops, AR/VRs, and even large-size TVs. In recent years, OLED materials with narrow spectra have been reported, which may be applied in BT.2020 displays [7,8]. Moreover, simulation results have shown that for future BT.2020 displays, OLEDs could consume 37% less power than a LED backlit LCD [9].…”

Design and fabrication of CuInS2/ZnS-based QLED for automotive lighting systems

“…Nevertheless, it is easier to achieve deeper red color with CuInS 2 QDs which can result in advantages to the design of state-of-the-art automotive lighting systems, particularly taillight applications 32,33 Moreover, the purity of the color in this automotive field relating to FWHM values might not be so critical comparing to electronic consumer displays and therefore great attention should be drawn in CuInS 2 QDs as emitting layer to form the QLED. Thus we selected CuInS 2 /ZnS as the main candidate for the QLED device manufacturing and modelling.…”
