Abstract: The present invention relates to a liquid crystal display (LCD) device. More particularly, the present invention relates to an LCD device including a thin film transistor (TFT) compensation circuit in an LCD device which implements a driving circuit by using an oxide TFT, the LCD device capable of compensating for degraded characteristics of a TFT due to threshold voltage shift. As the compensation circuit including a dummy TFT is formed on a non-active area of the LC panel, the degree of threshold voltage shift of the DT due to a DC voltage can be sensed. Based on the sensed result, a threshold voltage of a second TFT can be compensated. This can reduce lowering of a device characteristic.

Abstract: The present disclosure relates to a shift register, and more particularly, a shift register having a sensing circuit for quantitatively measuring a threshold voltage shifted level of a thin film transistor, which is deteriorated due to a continuously applied direct-current (DC) voltage, in a shift register having thin film transistors using oxide silicon as an active layer.The present disclosure may provide a shift register capable of overcoming an erroneous operation caused due to lowering of device characteristics, by further connecting a sensing transistor to thin film transistors configuring the shift register formed on a display panel to sense a level of threshold voltage shift, and driving the shift register by dividing one frame into odd and even periods according to the sensing result.
