Recovery Act: Low Cost Integrated Substrate for OLED Lighting Development
PPG Industries, Inc.
are highlighted that are based on the learning from the work done under the integrated substrate
development project and have the potential to achieve the cost metrics and performance targets
highlighted in the 2009 multi-year program plan (MYPP). The objective of this section is to outline
strategies to achieve DoE's integrated substrate cost targets of $26/m2 by 2015.
Background:
White OLEDs (WOLEDs) are considered a potential high efficiency, low cost, solid state replacement for
general lighting. While OLED lighting panels have been available since 2009, commercial offerings have
been limited to expensive luminaries for decorative applications and prototyping panel kits. Widespread
adoption of OLED-based solid-state lighting sources is constrained by the current high cost of these
devices.

Table 19 shows the projected costs (from the MYPP developed at the DOE SSL Manufacturing
Workshop, Vancouver, WA in June 2009) of sheet-processed OLED lighting panels. Highlighted in the
table are the projected costs for the integrated substrate (glass plus electrodes and light extraction; often
referred to as the foundation structure and defined in Figure 29) on which organic emitting layers of an
OLED device are fabricated. Target integrated substrate projected 2014 costs (sum of the substrate,
electrode, and light extraction layers costs) at $26/m2 represents 26% of the projected total OLED lighting
sheet processed panel cost.
