Abstract:
1. An x-ray detector comprising: an array substrate comprising: a plurality of blocks which extend along the array substrate in a first direction, each of the blocks including a plurality of cells that are each associated with a data line extending substantially in parallel with the first direction and a gate line extending substantially perpendicularly with respect to the first direction such that the data line crosses the gate line at a location of the cell, a thin film transistor respectively connected to the gate and data lines, and a photodiode, connected to the thin film transistor, which receives light converted from x-rays, the cells storing charges corresponding to an amount of the light; a plurality of gate drivers, arranged adjacent to a first side of the array substrate and connected to ends of the gate lines, which select rows of the cells associated with each of the gate lines through a scanning operation; and a plurality of read-out circuits, arranged adjacent to a second side of the array substrate and directly connected to ends of the data lines extending directly from the plurality of blocks, which read out charges stored in the cells, of each of the selected rows, that are respectively associated with each of the data lines extending directly from the plurality of blocks to which each of the read-out circuits are respectively directly connected.
