Abstract:
A driving circuit on a liquid crystal display (LCD) panel and associated control method is provided. The LCD panel connected to a display control circuit via a flexible print circuit (FPC) includes a master source driver, for inputting a digital image signal in compliance with a first electrical specification via an FPC board and converting the digital image signal to a gate driving signal and a slave source driving signal, which are in compliance with a second electrical specification; a gate driver, for receiving the gate driving signal in compliance with the second electrical specification; and a slave source driver, for receiving the slave source driving signal in compliance with the second electrical specification. The master source driver, the slave source driver and the gate driver drive a thin-film transistor (TFT) on the LCD panel.
