OLED EFFICIENCY COMPARISON WORKSHEET
Purpose: compare matching quantities, operating conditions and device boundaries.
Claim/source/date; sample or commercial product; sample count:
Metric and units: EQE / cd/A / lm/W / optical W per electrical W / other:
Spectrum or color coordinates, luminance, current/current density and temperature:
Active area, viewing/collection geometry and optical layers:
Electrical boundary: emitter/panel/driver/system; operating image or content:
Illustrative example: 120 lm / 1.5 W panel = 80 lm/W. At 80% driver efficiency, input is
1.875 W; adding 0.125 W controls gives 2 W and 60 lm/W system efficacy. Fictional values,
before further optical loss.
Roll-off data over the required brightness range:
Lifetime endpoint, initial output, drive method, temperature and measured/extrapolated
basis:
Color shift/uniformity/other failure criteria:
Application requirements met, mismatched conditions and missing evidence:
