Abstract

The present invention provides a display panel driving system, comprising a first IIC bus and a second IIC bus, a control board and a movement board, the control board is provided with a timing control chip and a driving chip, and the timing control chip includes a first host interface and a first Slave interface, the driver chip includes a second slave interface, the first host interface is connected to the second slave interface through the first IIC bus; The host interface is connected with the first slave interface through the second IIC bus. By setting the first IIC bus and the second IIC bus which are independent of each other, the separate transmission of information between the timing control chip and the system-on-chip, and the separate transmission of information between the timing control chip and the driver chip can be realized, and the technology that solves the conflict of the IIC bus question.

Description

Display panel drive system technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel drive system. Background technique [0002] Because the IIC bus (Inter-Integrated Circuit, integrated circuit bus) has fewer signal lines, small size and other advantages, it is widely used in LCD panel display panel drive systems. As shown in Figure 1, in the existing liquid crystal panel display panel drive system, including the control board 11, the movement board 12 and the IIC total Line 13. The control board 11 is provided with a timing control chip (TCON) 101 and a programmable gamma proofreading buffer circuit chip (P-gamma IC) 102 and a power management chip (Power manage IC, PMIC) 103, the core board 12 is provided with a system-on-chip (System on Chip, SOC) 104 and IIC device 105 . The timing control chip 101 includes a timing host for sending signals Interface 1011 and timing slave interface 1012 for...
