DISPLAY APPARATUS

摘要

An organic light-emitting diode display apparatus, comprising: an organic light-emitting diode display device (4), a polaroid (1) located above the organic light-emitting diode display device (4), and a liquid crystal layer located between the organic light-emitting diode display device (4) and the polaroid (1), wherein the direction of a slow axis of liquid crystals (3) in the liquid crystal layer forms a predetermined included angle with the direction of an absorption axis of the polaroid (1), so that external light incident to the organic light-emitting diode display device (4) from the polaroid (1) is reflected by the organic light-emitting diode display device (4) and then emitted out from the polaroid (1) when the organic light-emitting diode display device (4) is in a non-display state. The display device can be used as a clear mirror.
