The display technology based on high color purity light sources has the characteristics of wide achievable color gamut, good color saturation and high contrast ratio, which can bring people better visual experience. In recent years, the development of narrow bandwidth light sources is receiving more and more attentions. Here, three typical light-emitting polymers were selected to construct polymer light-emitting electrochemical cells (PLEC), and a distributed Bragg reflector (DBR) and Al thin film were used as cavities to narrow the emission spectra. The results showed that the bandwidth of the emitted light from the red, green and blue PLECs dramatically narrowed down to 10, 11 and 8 nm, respectively, and the color purity has been greatly improved. The acquisition of such high color purity light sources is expected to significantly promote the development of next-generation display technology.
- Distributed Bragg reflector,
- Polymer light-emitting electrochemical cell,
- Narrow bandwidth light sources,
- Peak position matching,
- High color purity
