Abstract:
1. A source driving system for driving a display panel, the source driving system comprising: a first source driving integrated circuit, comprising: a first source driver for receiving first display data, driving pixels in a first block of the display panel according to the first display data and generating a first display parameter according to the first display data; and a first power driver electrically connected to a voltage source and the first source driver for generating a first driving voltage to the first source driver; and a second source driving integrated circuit, comprising: a second source driver electrically connected to the first source driver for receiving second display data, driving pixels in a second block of the display panel according to the second display data, generating a second display parameter according to the second display data, and transmitting the second display parameter to the first source driver; and a second power driver electrically connected to the voltage source, the first source driver and the second source driver for generating a second driving voltage to the second source driver wherein the first source driver is further configured to generate a third display parameter according to the first and second parameters and to transmit the third display parameter to the second source driver; wherein when a difference between the first driving voltage and the second driving voltage is greater than a predetermined value, the first power driver transmits a power driving signal to the second power driver, and the second power driver adjusts the second driving voltage according to the power driving signal.
