Abstract
A lighting device especially suitable for automotive center-high-mounted-stop-light (CHMSL) and brake light applications is provided. The lighting device comprises a display panel having at least two interfaces therein, with at least one interface configured as a light reflective interface and at least one interface configured as a light emitting interface. At least a portion of light from a light source propagates through the display panel into contact with the light reflective interface and is reflected by the light reflective interface towards the light emitting interface using total internal reflection.
