摘要:
An LCD shift register having stages which use the Bootstrap effect and may only have three MIS transistors, as well as improvements to such a circuit having four or seven MIS transistors, are disclosed. The advantages are that the number of components used is reduced, the lifetime of the shift registers is extended, and it is possible to operate only with control signals having an amplitude 5 or 10 v lower than that of the output signals.

Mindestens ein weiterer Transistor bildet eine Lade und Entladestufe (II) für die Bootstrap-Kapazität.

A display panel (100) includes multiple gate lines (G1-G10) and a gate driver (120). The gate driver includes multiple shift registers (SR1-SR10, 200). Each of the shift registers includes a pull-up circuit (210), a driving circuit (220), and a pull-down circuit (230). The pull-up circuit charges a first node (NQ) in the shift register. The driving circuit is coupled to the first node, and outputs, according to a voltage signal of the first node, a driving pulse signal (G[n]) to a corresponding gate line. The pull-down circuit is coupled to the driving circuit, and discharges one of the gate lines according to the voltage signal of the first node. The shift register includes a first shift register (SRI) provided on a first side and a second shift register (SR2) provided on a second side. The pull-down circuit in the first shift register discharges a gate line corresponding to the second shift register according to the voltage signal of the first node.
