Claim Text:
1. A display apparatus, which is switchable between a first mode and a second mode, comprising: a transparent light emitting layer configured to display image in the first mode and be disabled in the second mode; a light modification layer, disposed at a first side of the transparent light emitting layer which is under the transparent light emitting layer and comprising a first substrate, a second substrate under and opposed to the first substrate, a plurality of electrodes disposed on the second substrate, a liquid crystal layer disposed between the first substrate and the second substrate, and a reflective layer disposed under the liquid crystal layer; and a first polarization layer disposed between the transparent light emitting layer and the light modification layer and configured to polarize an incident light which transmits through the transparent light emitting layer, wherein the light modification layer further comprises a first quarter waveplate disposed between the first polarization layer and the first substrate, and wherein when the display apparatus is operated in the first mode, the light modification layer is configured to absorb the incident light by the liquid crystal layer; and when the display apparatus is operated in the second mode, the light modification layer is configured to reflect the incident light by the reflective layer so that the incident light is reflected as a reflected light transmitting through the transparent light emitting layer.
