OLED Chemical Profiles in Discarded Smartphone Screens

A chemical analysis dataset identifies 24 OLED-related compounds, including 22 confirmed with standards, in discarded smartphone screens. It separates each screen into a display functional laminate and a module carrier layer for chemical profiling. The total chemical burden per screen ranges from 2.24 to 14.6 μg.

Use Cases

• Analyze the distribution of 24 identified OLED compounds, such as aryl boronic acids, between the display functional laminate and module carrier layer.
• Model the total chemical burden per screen (2.24-14.6 μg) against screen characteristics or waste stream data.
• Compare chemical composition profiles across screens to infer consistency in manufacturing practices for the display functional laminate.
• Investigate the potential redistribution of specific compound classes, like triarylamines or carbazole motifs, within the screen module during its lifecycle.

Strengths

• Contains 24 identified OLED-related compounds, with 22 confirmed using analytical reference standards.
• Provides quantitative data on total chemical burden per screen, with a measured range from 2.24 to 14.6 μg.
• Structures data by separating each screen into two distinct functional layers (display functional laminate and module carrier layer) for analysis.

Limitations

• The dataset is small (6.5 MB), suggesting a limited sample size of analyzed smartphone screens.
• The geographic origin of the discarded smartphone screens is not specified, limiting generalizability.
• Chemical quantification is described as semi-quantitative, not fully quantitative.
