1. A flexible organic X-ray detector having a layered structure, comprising:
a flexible substrate;
a thin glass substrate operatively coupled to the flexible substrate by way of a permanent adhesive, a temporary adhesive, or a combination thereof;
a thin film transistor array disposed on the thin glass substrate;
an organic photodiode comprising one or more layers disposed on the thin film transistor array; and
a scintillator layer disposed on the organic photodiode;
wherein the organic photodiode comprises one or more materials that produce charged carriers between a first electrode and a second electrode following conversion of incident X-ray radiation to optical photons by the scintillator layer, such that the organic photodiode includes at least one electron donor material and an electron acceptor material.
