    • A backlit label includes a transparent element and a transflective element positioned at the backside of the transparent element. The transparent element passes light bi-directionally, whereas the transflective element passes light received from a first direction and reflects light received from an opposite direction. A backlight source, which may or may not be integrated with the label, produces backlighting for the label. The transflective element passes the backlight that emanates from behind out through the transparent element. However, for ambient light received from in front of the label, the transflective element reflects the ambient light back out through the transparent element.
    • 背光标签包括位于透明元件背面的透明元件和半透反射元件。 透明元件双向通过光,而透反射元件透过从第一方向接收的光并反射从相反方向接收的光。 可能或可能不与标签集成的背光源为标签产生背光。 半透反射元件通过透明元件将从后面发出的背光传递出去。 然而,对于从标签前面接收的环境光,透反射元件通过透明元件反射环境光。
