Recent progress of organic light-emitting diode microdisplays for augmented reality/virtual reality applications

“…The 0.11μm CMOS process was used and the subpixel size was 3.6 × 10.8 μm. Xue et al also reported that the Al electrode that was fabricated using the standard CMOS processes after chemical mechanical polishing (CMP) had residual organic contaminants and a thin Al oxide layer on the surface, which were seen using x-ray photoelectron spectroscopy, as shown in Figure 2(i) [24]. They demonstrated a green SVGA OLED microdisplay with a pixel size of 15 × 15 μm, as shown in Figure 2(j).…”

Ca9La(PO4)7:Eu2+,Mn2+: a radiation-adjustable phosphor usable for high-perfomance white light-emitting diodes

“…We compressed the testing portions of powder and subjected them to excitation at an incidence angle of 45 o . To have the green-phosphor CaLa:EM, its essential chemical components and creation process are presented in Table 1 Photomultiplier of the form Hamamatsu Photonics R928 at 90 0 angle to the stimulation ray Time-resolved measurements Adjustable nanosecond optical-parametric-oscillator/Q-switch-pumped YAG:Nd 3+ laser formation (NT341/1/UV, Ekspla) Radiation transients Obtained using nanochromater (ARC's SpectraPro300i), detected using a photomultiplier tube (R928HA, Hamamatsu), linked to a digital oscilloscope (LT372, LeCrop) as well as transmitted towards a computer to study kinetics [9], [10] We created WLED lightings via combining clear silicon resin with phosphor mixture of CaLa:EM along with BaMgAl 10 O 17 :Eu 2+ above an ultraviolet chip (AOT Product No: DC0004CAA, Spec: 370U02C, maximum wavelength: 365 ~370 ± 0.6 nm, chip size: 40x40 mil, forward voltage: 3.8 ~4.0 ± 0.02 V, power: 10-20 ± 0.21 mW). All samples had their chromaticity coordinates evaluated by the Commission International de I'Eclairage (CIE).…”

Design of white tandem organic light‐emitting diodes for full‐color microdisplay with high current efficiency and high color gamut

“…The OLED device should have a top-emitting structure as the microdisplay is fabricated on a silicon substrate [9,10]. In a top-emitting structure, a thin metal layer is generally applied as a top electrode.…”
