X - ray sensor technology introduction

Applications of X-ray sensors：

Health care

Security check

Industrial nondestructive testing

The part that we developed：

What we are working on is the part inside the red box, which is the core of the X-ray sensor.

At the lower right of the figure are the film layers and circuit designs in the red box.

The working principle：

After the X-ray is transformed into visible light by the scintillator, it is irradiated to the PIN photodiode to produce photogenerated carriers, which output electrical signals through the TFT.

Using IGZO material as the active layer of TFT, its signal-to-noise ratio, leakage current, required exposure dose, cost and so on are better than amorphous silicon
