摘要： The liquid crystal display (LCD) driving system contains a Printed Circuit Board (PCB), a Timing Controller, Source Drivers, an Inter-Integrated Circuit (I2C) bus, and Gate Drivers. The Timing Controller is configured on the PCB for transforming control signals from the LCD to data and scan control signals. The I2C bus connects the Timing Controller to the Source Drivers. The Timing Controller delivers data and scan control signals to the Source Drivers through the I2C bus following a protocol. The Gate Drivers are electrically connected to the Source Drivers for receiving scan control signals. The driving system is capable of employing fewer transmission wires to deliver the same control signals of the prior art from the Timing Controller by configuring I2C bus between the Timing Controller and the Source Drivers, thereby reducing wiring area on the PCB and wiring difficulty. A LCD driving method is also provided.

摘要： The present invention provides a driving method for a display panel, a timing controller and a liquid crystal display. The method includes: when detecting that an image frame to be displayed is an overloaded image, a timing controller switches an operation frequency from a first frequency to a second frequency; outputting a timing control signal to a source driver with the second frequency such that after the source driver receives the timing control signal, the source driver outputs the data driving signal having a lower frequency to drive the display panel to display the overloaded image; wherein the first frequency is higher than the second frequency. Through the above way, the output power consumption of the source driver when displaying an overloaded image is decreased, and avoid rising temperature to affect the display quality.
