Abstract
A driver signal control circuit for a display panel is proposed. A timing controller is connected to an input terminal of a gate voltage shaping controller and a first FET. A first output terminal of the gate voltage shaping controller is connected to a gate of the first FET. A drain of the first FET is connected to the output terminal of the control circuit. A second output terminal of the gate voltage shaping controller is connected to a gate of the second FET, and a source of the second FET is connected to the output terminal of the control circuit. A second terminal of the discharge passage is connected to an output terminal of the control circuit. The control circuit effectively prevents the production costs when display panels with different production batches are fabricated using different fabrication processes.
