AI Technical Summary
Existing color display devices for vehicle interiors and exteriors struggle with visibility issues due to insufficient luminance and designability, particularly when exposed to external illumination, and fail to exhibit achromatic black color when the light source is turned off, making steps and joints visible.
A color display device comprising a colored light-transmitting base material with a total light transmittance of 18% or less, combined with a light-blocking base material and a light source unit, where the light source is positioned to transmit emission light through the colored base material, ensuring high luminance and achromatic black appearance when the light is off.
The solution provides a color display device with excellent designability and high luminance, suitable for large vehicle components, ensuring visibility from a distance and concealing steps and joints when the light is off.
