Embodiment 1
[0023] see figure 1 , is a partial cross-sectional schematic view of the organic light emitting display device according to Embodiment 1 of the present invention. The organic light emitting display device mainly includes a substrate 1 , an organic light emitting device 2 (OLED) formed on the substrate 1 , and an encapsulation cover 3 covering the organic light emitting device 2 and fixed on the substrate 1 . The organic light-emitting display device of Example 1 is a top emission type, such as figure 1 As shown, the light emitted by the organic light-emitting device 2 is emitted from one side of the packaging cover 3, and the packaging cover 3 is made of a photochromic polarizer.
[0024] Wherein, the substrate 1 may be an existing substrate. The organic light emitting device 2 may adopt an existing organic light emitting device.
[0025] In Embodiment 1, the photochromic polarizer used in the package cover plate 3 is a polarizer containing a photochromic substance.

Embodiment 2
[0041] The organic light-emitting display device according to Embodiment 2 of the present invention mainly includes a substrate 1 , an organic light-emitting device 2 (OLED) formed on the substrate 1 , and an encapsulation cover 3 covering the organic light-emitting device 2 and fixed on the substrate 1 . The relative positions and general structures of the substrate 1, the organic light-emitting device 2 and the packaging cover plate 3 are basically the same as those in Embodiment 1, see figure 1 ; The difference from Example 1 is that the organic light-emitting display device of Example 2 is a bottom emission type, and the light emitted by the organic light-emitting device 2 is emitted from the side of the substrate 1; the substrate 1 is made of a photochromic polarizer.
[0042] Wherein, the organic light emitting device 2 may be an existing organic light emitting device. The packaging cover plate 3 may use an existing cover plate.
[0043] In Embodiment 2, the photochromi...
