A dual emitting device includes a transparent substrate and an array of
pixels. The array of pixels is disposed on the transparent substrate, and
each pixel of the array includes at least one first sub-pixel and at
least one second sub-pixel. The first sub-pixel includes a first OLED
driven by a first TFT, and a first sheltering layer on the first OLED.
The second sub-pixel includes a second OLED driven by a second TFT, and a
second sheltering layer formed between the transparent substrate and the
second OLED.
