Abstract:
1. A double sided display, comprising: a first substrate; a first organic light-emitting device (OLED) formed on the first substrate; at least a plurality of first spacers independently disposed on the first substrate and distributed at positions within the area of the first OLED correspondingly, and parts of the first spacers being disposed close to and along a lateral side of the first OLED; a second substrate substantially opposite to the first substrate; a second OLED formed on the second substrate, wherein the second OLED is disposed opposite to the first OLED, and a gap is formed between the first and second substrates; at least a plurality of second spacers independently disposed on the second substrate and distributed at positions within the area of the second OLED correspondingly, and parts of the second spacers being disposed close to and along a lateral side of the second OLED, wherein only parts, but not all, of the first spacers are substantially in alignment with corresponding parts of the second spacers; and a sealing adhesive adhering the first substrate and the second substrate; wherein a height of the first spacer is larger than a thickness of the first OLED and smaller than a depth of the gap, and a height of the second spacer is larger than a thickness of the second OLED and smaller than the depth of the gap.
