Definitions

The complexity of the process increases costs and reduces reliability and aperture ratio.
- the mobility of the a-Si material hardly exceeds lcn ⁇ V- 1 , and thus the existing TFT array substrate is difficult to meet the demand for an increasingly large-sized liquid crystal television and a higher-performance driving circuit.

Moreover, the fabrication of oxide TFTs is compatible with existing LCD production lines and is easy to transform. Therefore, oxide TFTs have attracted much attention and have become a recent research hotspot.
