VARIABLE SYMBOL DISPLAY UNIT CAPABLE OF IMPLEMENTING QUICK VISUAL RECOGNITION

摘要

PURPOSE: A variable symbol display unit is provided to increase the visibility of a driver by providing selective light transmission in accordance with the wavelength band of light.;CONSTITUTION: A circuit board is arranged at a housing(100). A light source part(300) includes a first wavelength light source and a second wavelength light source. A transparent filter substrate is arranged to be separated from the light source part. An optical filter part(400) changes the output region of light according to the operation of the light source part. A filter layer selectively allows responses to first wavelength light or second wavelength light.;COPYRIGHT KIPO 2013
