Patent ID: 8760597

Claim:
A switching device comprising: at least two thin film transistors (TFTs) connected in series; and at least two gate lines respectively connected to the at least two TFTs, wherein a number of the at least two gate lines in each pixel row of an active display device is equal to a number of the at least two TFTs, the at least two gate lines being connected to TFTs in only one pixel row, wherein, the switching device is configured to, during a pixel charging time, apply a positive gate voltage to at least two gate lines such that the at least two TFTs are turned on, the pixel charging time being a time when a data voltage is applied to a pixel associated with the at least two TFTs, and the switching device is configured to, during times other than the pixel charging time, turn off at least one of the at least two TFTs and turn on remaining ones of the at least two TFTs.
