AI Technical Summary
⚠Technical Problem
At low temperatures or when the TFT film quality is poor, the fall time of the Gout signal increases, leading to the risk of incorrect charging.
⚗Method used
By optimizing the output signal circuit and utilizing the adjustment module and the switching module, the switching module is controlled to turn on and off according to the change of the first clock signal, so as to quickly transmit the low voltage of the constant low voltage signal terminal to the output signal terminal and reduce the fall time of the Gout signal.
🎯Benefits of technology
It effectively prevents the risk of incorrect charging of the Gout signal, simplifies circuit layout, reduces signal fall time, and is suitable for any TFT_LCD GDL architecture.

Abstract
The application relates to the technical field of liquid crystal display, and discloses an optimized output signal circuit, a control method, an assembly and a display panel. The optimized output signal circuit is connected with a signal end of a control end driver circuit. The optimized output signal circuit comprises an adjusting module and a switching module. The signal end comprises a first clock signal end, an output signal end and a constant low-voltage signal end. The first clock signal end is connected with the adjusting module. The adjusting module is connected with the switching module. The switching module is connected between the output signal end and the constant low-voltage signal end. Therefore, the application can reduce the falling time of a Gout signal of the output signal end, thereby preventing the risk of causing wrong charging.
