Wide color-gamut vehicle infotainment display system with quantum dot element

A vehicle infotainment system, comprising:

• a processor configured to generate digital images;
• and
• a display device for displaying the digital images that includes:
• an array of multiple blue light-emitting diodes (LEDs) that are each configured to generate a blue output light;
• a nanocrystal material that is disposed at a first position along a path of light from the array of blue LEDs to a liquid crystal module, the nanocrystal material configured to receive the blue output light,
• wherein at least a first portion of the nanocrystal material is configured based on a first shape and converts a first portion of the blue output light to a green light emission having a first peak wavelength,
• wherein at least a second portion of the nanocrystal material is configured based on a second shape and converts a second portion of the blue output light to a red light emission having a second peak wavelength, wherein the second shape is different from the first shape, and
• wherein at least a third portion of the nanocrystal material is configured to transmit a remainder portion of the blue output light;
• a color filter assembly disposed at a second position along the path of light, wherein the second position is located along a path from the first position to the liquid crystal module, wherein the color filter assembly is configured with a first passband that is configured to match the first peak wavelength, a second passband that is configured to match the second peak wavelength, and a third passband that includes a peak wavelength of the remainder portion of the blue output light;
• and
• the liquid crystal module configured to receive the green light emission passed through the color filter assembly, the red light emission passed through the color filter assembly, and the remainder portion of the blue output light passed through the color filter assembly and generate an image that includes a portion of the green light emission, a portion of the red light emission, and a portion of the remainder portion of the blue output light,
• wherein the first position at which the nanocrystal material is disposed comprises an outer surface of at least one blue LED included in the array of blue LEDs and forms an outermost surface of an LED assembly in which the at least one blue LED is disposed.
