SHIFT REGISTER BASED ON FIELD-EFFECT TRANSISTORS

A shift register, each stage thereof provided to drive a corresponding output line, includes an output transistor that drives the output line and an additional transistor of the same technology and of the same polarity as the output transistor. The additional transistor is connected in such a way as to be subject to bias conditions similar to the output transistor, such that the additional transistor's threshold voltage, identical at the start of life to that of the output transistor, drifts as quickly or more quickly as the threshold voltage of the output transistor. The additional transistor is used to adjust the precharging voltage of a gate of the output transistor to its conduction performance characteristics during the precharging and/or selection phase.
