Patent ID: 7633091

Claim:
An image TFT array for an indirect X-ray sensor, comprising: a substrate; at least one first line, a lower electrode, a pad electrode, a common electrode and a first electrode connected with the first line positioned on the surface of the substrate; an insulation layer positioned on the substrate and the at least one first line, the lower electrode, the pad electrode, the common electrode and the first electrode; an island positioned on the first electrode; at least one second line cross-intersecting the first line, an upper electrode positioned corresponding to the lower electrode, a second electrode connected with the second line and a third electrode connected with the upper electrode positioned on the insulation layer, wherein the lower electrode and the upper electrode have an approximately the same size of area; a passivation layer covering the substrate, the at least one second line, the upper electrode, the second electrode, and the third electrode; and a first through hole positioned on the common electrode, and a second through hole positioned on the pad electrode, and an aperture positioned to expose a portion of the upper electrode.
