INTEGRATED SOURCE DRIVING SYSTEM
First Claim
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 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;
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.

Abstract
A source driving system includes first and second source driving integrated circuits. The first driving integrated circuit includes a first source driver for receiving first display data and driving pixels in a first block of a display panel according to the first display data. The second source driving integrated circuit includes a second source driver electrically connected to the first source driver for receiving second display data and driving pixels in a second block of the display panel according to the second display data. The first and the second source drivers generate first and second display parameters according to the first and the second display data respectively. The second display parameter is transmitted from the second source driver to the first source driver. The first source driver generates a third display parameter according to the first and second parameters and transmits the third display parameter to the second source driver.
