Problems solved by technology

[0003] However, the circuit board 130 of the conventional display device 100 contains the above-mentioned components, resulting in a relatively large area of ​​the circuit board 130, thereby occupying a considerable space inside the display device 100.
Therefore, the existing display device 100 cannot further reduce the appearance size due to the large area of ​​the circuit board 130

Abstract

The present invention discloses an integrated source driving system. The source driving system comprises a first source driving integrated circuit and a second source driving integrated circuit. The first source driving integrated circuit comprises the following components: a first source driver, and a pixel which is used for receiving first display data and drives pixels of a first block of the display panel according to the first display data. The second source driving integrated circuit comprises a second source driver which is electrically connected with the first source driver for receiving second display data and drives pixels of a second block of the display panel according to the second display data. The first source driver generates a first display parameter according to the first display data. The second source driver generates a second display parameter according to the second display data. The first source driver generates a third display parameter and transmits the third display parameter to the second source driver according to the first display parameter and the second display parameter.

Description

technical field [0001] The invention relates to a source driving system of a display device, in particular to a space-saving integrated source driving system. Background technique [0002] Please refer to figure 1 , figure 1 is a schematic diagram of a conventional display device 100 .
