deposition has been optimized for best quality at 250°C for the 250°C and 285°C processes, and at 200°C for the 200°C process [12] [13] [14]. Dry etching is used next to pattern the a-Si:H islands and open contact vias to the bottom metal. The top metal (Cr/Al based) is then thermally evaporated and patterned by wet etching. The n + a-Si:H is then cut at the backside of the a-Si:H channel by dr...

This paper considers the effects on human body of flicker organic light-emitting diode (OLED) displays. Related studies have been conducted due to reports cases adverse health use artificial lighting. Interest in this problem recently intensified with development various new displays and longer exposure time people them. Therefore, previous lighting are described paper, based them, dimming tech...

Exploiting our recently developed bilayer interface methodology, together with a new wide energy-gap, low LUMO acceptor (A) and the designated donor (D) layers, we succeeded in fabricating an exciplex-based organic light-emitting diode (OLED) systematically tuned from blue to red. Further optimization rendered a record-high blue exciplex OLED with η(ext) of 8%. We then constructed a device stru...

Preparation of dense alumina (Al₂O₃) thin film through atomic layer deposition (ALD) provides a pathway to achieve the encapsulation of organic light emitting devices (OLED). Unlike traditional ALD which is usually executed at higher reaction n temperatures that may affect the performance of OLED, this application discusses the development on preparation of ALD thin film at a low temperature. O...

Organic light-emitting diode (OLED) microdisplays have attracted much attention as displays for small form factor augmented reality (AR) devices. To realize glass-like thin and wide field of view (FoV) AR devices, we designed a display module with high aspect ratio microdisplay optical component. For the microdisplay, developed color OLED 32:9 0.8-inch diagonal ∼2,490-ppi CMOS backplane. expres...
