Abstract
The invention provides an array substrate and activation method for TFT elements in the array substrate. The array substrate comprises a shielding metal layer (10) and a TFT layer (20) disposed on the shielding metal layer (10); by connecting the shielding metal blocks (11) on the shielding metal layer (10) to electricity to heat up the shielding metal blocks (11) for pre-heating the TFT layer (20) to accelerate activating the TFT elements in the TFT layer (20). The activation method, by connecting the shielding metal blocks (11) on the shielding metal layer (10) to electricity to heat up the shielding metal blocks (11) for pre-heating the TFT layer (20) before activating the TFT elements in the TFT layer (20), accelerates activating the TFT elements in the TFT layer (20). The method is applicable to activating the TFT elements in array substrate in low temperature environment.
