Abstract
Particular embodiments described herein provide for an electronic device that can be configured to include a keycap with photoluminescent material, a light energy source to emit light energy at a wavelength to activate the photoluminescent material, and an ambient light sensor to activate the light energy source during low ambient light conditions. In an example, the photoluminescent material is quantum dot material.
Claims20
An electronic device comprising:
- a keycap with photoluminescent material;
- a light energy source to emit light energy, wherein the photoluminescent material can absorb the light energy at a specific wavelength and reemit the light energy at a higher wavelength;
- and
- an ambient light sensor to activate the light energy source during low ambient light conditions.
1 more element
A mobile computer comprising:
- a first housing that includes a display and a light energy source to emit light energy to activate photoluminescent material;
- and
- a second housing that includes a keyboard with a plurality of keys that have a keycap that includes the photoluminescent material, wherein the photoluminescent material can absorb the light energy at a specific wavelength and reemit the light energy at a higher wavelength.
A method comprising:
- determining an amount of ambient light in an area around a keyboard, wherein the keyboard includes a plurality of keys and each key has a keycap that includes photoluminescent material that can absorb light energy at a specific wavelength and reemit the light energy at a higher wavelength;
- and
- when the determined amount of ambient light is below a threshold, activating a light energy source to direct light energy to the keys with the keycap that include the photoluminescent material to activate the photoluminescent material.
