Abstract
A transflective display () includes a backlight () and a display stack ('). The display stack () includes a first electro-optic layer () configured to modulate light of a first waveband and a second electro-optic layer () configured to modulate light of a second waveband that is different from the first waveband. A mirror () is positioned between the first and second electro-optic layers () such that the first electro-optic layer () is positioned adjacent to a first surface (S) of the mirror () and has a surface (S) that is configured to face an external light source (), and the second electro-optic layer () is positioned adjacent to a second surface (S) of the mirror () and has a surface (S) that is configured to face the backlight (). The mirror () is also configured to partially reflect and partially transmit wavelengths in the first waveband and to at least partially transmit wavelengths in the second waveband.
