Abstract
The present invention discloses an organic light emitting diode flexible array substrate including a displaying region, a folding region adjacent to the displaying region, a flexible substrate, barrier layer, a buffer layer, a polycrystalline layer stacked together, a first insulation layer disposed on the buffer layer and covering the polycrystalline layer, a first metal layer, a second metal layer, and a third metal layer. Folding signal lines are formed on a portion of the second metal layer in the folding region. Folding signal lines are formed on a portion of the third metal layer in the folding region. Double folding signal lines of the second metal layer and third metal layer drastically increase reliability and lifespan of the signal lines in the folding region.
