Claim:
1. A TFT-LCD array substrate having a display area and a peripheral area surrounding the display area, the display area comprises a plurality of gate lines and data lines connecting to TFTs arranged within the display area, the peripheral area comprising: a plurality of data testing lines for respectively transmitting data testing signals to each of the data lines in the display area; a plurality of gate testing lines for sending gate testing signals to the gate lines within the display area; a common electrode line for providing a common electrode for the TFTs within the display area; and wherein each of the data testing lines and the gate testing lines comprise a fast testing switch device for connecting or disconnecting the data testing lines and the gate testing lines with the display area when being controlled by external switch control signals; and wherein the fast testing switch device comprises at least one first switch TFT, a gate of the first switch TFT connects to at least one control chip and a testing block for receiving the switch control signals from the testing block or turn-off control signals from the control chip, a source of the first switch TFT connects to one data testing line or one gate testing line, and a drain of the first switch TFT connects to the corresponding data line or gate line of the display area, wherein the testing block is arranged on a starting end of each of the data testing lines and the gate testing lines; and wherein the fast testing switch device is turned off upon receiving the turn-off control signals.
