Flexible display apparatus

A flexible display apparatus, comprising:

• a flexible substrate doped with uniformly distributed first nano-particles, an organic electroluminescent device, and a plurality of thin film transistors disposed between the flexible substrate and the organic electroluminescent device;
• a thin film packaging layer and an organic photoresist layer disposed on the thin film packaging layer, the organic photoresist layer consisting of a material doped with uniformly distributed second nano-particles;
• a display screen comprising the organic photoresist layer;
• wherein the organic electroluminescent device comprises a first electrode and a second electrode both disposed on the thin film transistors, and an organic light emitting layer disposed between the first electrode and the second electrode, wherein the thin film transistors control the first electrode and the second electrode to cause the organic light emitting, layer to emit light;
• wherein an arrangement of the first electrode, the thin film transistors, and the flexible substrate is structured and configured together such that first light emitted from the organic light emitting layer is first refracted by the first electrode, then refracted from the thin film transistors, and then refracted from the uniformly distributed first nano-particles to an external environment;
• and
• wherein an arrangement of the second electrode, the thin film packaging layer, and the organic photoresist layer are structured and configured together such that second light emitted from the organic light emitting layer is first refracted by the second electrode, then refracted by the thin film packaging layer, and then refracted from the uniformly distributed second nano-particles to the display screen externally.
