Large bendable radiation detector

A radiation detector for detecting radiation, comprising:

• a first radiation detection panel, which is flexible, extending in a first direction and detecting radiation incident on a front surface;
• and
• a second radiation detection panel, which is flexible, extending in the first direction and detecting radiation incident on a front surface, wherein at least a portion of a rear surface of the first radiation detection panel overlaps at least a portion of a front surface of the second radiation detection panel,
• wherein:
• the first radiation detection panel comprises a first TFT panel comprising a first active region in at least a portion of the first TFT panel;
• wherein the second radiation detection panel comprises a second TFT panel comprising a second active region in at least a portion of the second TFT panel;
• and
• wherein the first active region and the second active region overlap, or a line connecting one side of the first active region and the other side of the second active region is parallel to a third direction.
