Abstract
A light-emitting device having a pixel comprising a first non-tuneable sub-pixel configured to emit light at a first non-tuneable wavelength and a tuneable sub-pixel configured to emit light at a tuneable wavelength. The tuneable sub-pixel comprises a primary light-emitting material configured to emit light at a primary wavelength in response to a primary electrical input; and a tuning element configured to modify the primary wavelength to a secondary wavelength, wherein the secondary wavelength is tuneable, in response to a secondary electrical input.

A light-emitting device having a pixel comprising:
- a first non-tuneable sub-pixel configured to emit light at a first non-tuneable wavelength;
- and
- a tuneable sub-pixel configured to emit light at a tuneable wavelength, wherein the tuneable sub-pixel comprises:
- a primary light-emitting material configured to emit light at a primary wavelength in response to a primary electrical input;
- and
- a tuning element configured to modify the primary wavelength to a secondary wavelength, wherein the secondary wavelength is tuneable, in response to a secondary electrical input;
- and
- wherein the primary light emitting material comprises a light emitting molecule configured to emit light at wavelengths tuneable between the primary wavelength and the secondary wavelength by applying an electric field via the secondary electrical input so as to influence molecular topology of the light emitting molecule.
