Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Known displays for aerosol-generating devices suffer from undesired color tinting due to window material attenuation of certain light wavelengths, particularly in dead-front displays, which compromises color accuracy and control.
Innovation Solution
Incorporation of a nano-photonic material over the display window that generates and radiates light of predetermined wavelengths in response to backlighting, compensating for wavelength attenuation and enhancing color control through plasmonic resonance of nano-structures.

Engineering Contradiction Analysis
1Shape
If a dead-front display uses window material to attenuate certain wavelengths of light, then the colour of the window corresponds to the colour of the device in non-operational state, but the window material imparts an undesired tint to the illuminated window when backlit
Solution Approach 1:
A nano-photonic material layer is introduced as an intermediary between the backlight and the window material. This intermediate layer compensates for the wavelength attenuation caused by the window material, ensuring accurate color representation while maintaining the dead-front display's aesthetic appearance.
Solution Approach 2:
The nano-photonic material changes the optical parameters of the light by selectively enhancing certain wavelengths through plasmonic resonance. This modifies the light's spectral composition to counteract the window material's attenuation characteristics, restoring color accuracy.
2Loss of information
If a light source emits light of specific wavelengths to provide color indication, then the display can indicate device status, but the window material attenuates certain wavelengths causing color inaccuracy
Solution Approach 1:
The nano-photonic material serves as a mediator that ensures accurate color information transmission from the backlight to the user's eye. It compensates for the window material's harmful attenuation effect, making the color indication reliable and accurate for device status communication.
Solution Approach 2:
The nano-photonic material modifies the spectral parameters of the backlight by enhancing specific wavelengths through plasmonic resonance. This ensures that the color information conveyed to the user accurately reflects the device status without distortion from window material attenuation.

AI summary
A display for an aerosol-generating device is disclosed. The display comprises a notification window and a nano-photonic material extending over a front surface of the window. In one aspect, the nano-photonic material is configured to generate and radiate therefrom light comprising at least on one predetermined wavelengths in response to a light wave backlighting the window and being incident on the nano-photonic material. In another aspect, the nano-photonic material is configured to, in response to a light wave comprising at least one predetermined wavelength backlighting the window and being incident on the nano-photonic material, increase the amplitude of the at least one predetermined wavelength and emit therefrom a light wave comprising the at least one predetermined wavelength with the increased amplitude.
