Array substrate and radiation detector

Abstract

An array substrate according to an embodiment includes: a substrate having a first side extending toward a first direction and a second side extending toward a second direction intersecting the first direction; a plurality of Control lines; a plurality of data lines provided on the substrate and extending toward the second direction; photoelectric conversion parts respectively provided in a plurality of regions divided by the plurality of control lines and the plurality of data lines; provided on the substrate The peripheral area of ​​the above-mentioned second side of the above-mentioned second side, and the first area provided with a plurality of first wiring pads electrically connected to the control line; and the peripheral area of ​​the above-mentioned first side of the above-mentioned substrate, and provided with A plurality of second regions of the second wiring pads electrically connected to the data lines. The array substrate is at least one of the following two situations, wherein: the distance between the centerline of the first region extending in the first direction and the first side is smaller than the distance between the region containing a plurality of the control lines. The distance between the center line extending in the first direction and the first side is long, and the plurality of control lines are electrically connected to the plurality of first wiring pads provided in the first region; The distance between the center line extending in the second direction and the second side is longer than the distance between the center line extending in the second direction and the second side of the region containing a plurality of the data lines, and the plurality of The data line is electrically connected to the plurality of second wiring pads provided in the second region.

Description

technical field [0001] Embodiments of the present invention relate to an array substrate and a radiation detector. Background technique [0002] In a radiation detector such as an X-ray detector, an array substrate having a scintillation layer for converting radiation into fluorescence and a photoelectric conversion element for converting fluorescence into signal charges, and a circuit substrate having a control circuit and Amplifying / converting circuit; a flexible printed substrate electrically connecting the control line provided on the array substrate to the control circuit of the circuit substrate; and a flexible printed substrate electrically connecting the data line provided on the array substrate to the amplifying / converting circuit of the circuit substrate, etc. . [0003] In addition, a plurality of wiring pads electrically connecting the control lines to the flexible printed substrate are provided on the peripheral region of the array substrate. [0004] A plural...

Problems solved by technology

[0013] Therefore, if the distance between the area where the wiring pads and the like on the control circuit side are provided and the area where the wiring pads and the like are provided on the amplification / conversion circuit side becomes shorter in the circuit board, there will be electronic components constituting the control circuit. Possibility that the distance between the device and the electronic components constituting the amplification / conversion circuit becomes too short, making the arrangement of the electronic components difficult

[0014] As a result, there is a possibility that the miniaturization of the radiation detector cannot be realized
