摘要:
Applying quantum dots to surface features of an electronic device to augment or replace reflective and transmissive features. Applying quantum dots can yield more efficient illumination of those features and can permit use of diverse internal light sources to cause those features to emit any color of visible light. An electronic device, keyboard for same and method of applying features to areas of the exterior surface of an electronic device are provided. Quantum dots are applied to an area of the exterior surface that is illuminated by the device's internal light source. The quantum dots absorb incident light then emit predetermined longer wavelength light. The interior light may be a UV light, high energy light emitting diode, or back light. The quantum dots can be applied to exterior surfaces, buttons or key on electronic devices, mobile devices, and keyboards for mobile devices.
