Abstract
A detection substrate, a ray imaging device, and a method for driving a detection substrate are provided. The detection substrate includes a base substrate; a plurality of sensing TFTs; a plurality of signal read lines; a compensation TFT row including a plurality of compensation TFTs, wherein a first electrode of each of the compensation TFTs is electrically connected to the same signal read line as first electrodes of the sensing TFTs in corresponding sensing TFT column. As for the sensing TFTs and the compensation TFT electrically connected to the same signal read line, the first electrodes of both the sensing TFTs and the compensation TFT are source electrodes or drain electrodes, source-drain directions of the sensing TFTs are consistent with one another, and a source-drain direction of the compensation TFT is opposite to each of the source-drain directions of the sensing TFTs.
