Optimal Design of a Quantum Dot Color Conversion Film in LCD Backlighting
The design of the quantum dot (QD) color conversion film in the liquid crystal display (LCD) backlighting is optimized in terms of reducing the required amount of relatively expensive QD materials. It is demonstrated for the first time that a dichroic filter on the QD color conversion film can be op...

| description | The design of the quantum dot (QD) color conversion film in the liquid crystal display (LCD) backlighting is optimized in terms of reducing the required amount of relatively expensive QD materials. It is demonstrated for the first time that a dichroic filter on the QD color conversion film can be optimized in terms of its blue emission transmittance, which results in a reduction of over 30% of the amount of QD materials required, while maintaining the targeted color coordinate, color gamut, and the optical output of the backlight. In addition, it is found for the first time, that there is a strong impact of the reflectance of the backlight reflector on the optical output when a dichroic filter is employed. The significant implication of the present simulation results to the optimal design of more efficient backlight for LCDs is outlined. |
