Abstract: The present invention relates to a field of LCD technology, especially to a testing circuit for PSVA and array. The testing circuit for PSVA and array has gate signal lines, data signal lines, a first solder pad and thin-film transistors. Extension lines of the gate signal lines and the data signal lines are each connected to a drain of a corresponding one of the thin-film transistors. Sources of the thin-film transistors corresponding to the data signal lines are connected to each other and connected to the first solder pad. Gates of the thin-film transistors corresponding to the data signal lines are connected to a transfer structure on a substrate. Sources and gates of the thin-film transistors corresponding to the gate signal lines are connected to each other and connected to the transfer structure. Comparing with conventional testing circuit for PSVA and array, techniques provided by the present invention effectively reduces the number of solder pads at glass edges and simplifies complexity of overall circuit.
