Abstract
A driving circuit for a display panel and a method of driving the same are provided. The driving circuit includes that, when the time control chip is at an initialized state, the enabling control module controls the logic control module to turn off; and when the time control chip is at a state after the initialized state is finished the enable control module controls the logic control module to turn on to receive the modulating data provided by the time control chip.

A driving circuit for a display panel, comprising:
- a source driving chip connected to the display panel and configured to store a modulating data and to provide a data signal to the display panel;
- a time control chip configured to obtain the modulating data;
- and
- a gamma chip comprising an enabling control module and a logic control module, wherein the enabling control module is connected to the time control chip and configured to control the logic control module turning on or off according to an enabling signal output by the time control chip;
- wherein the enabling control module controls the logic control module to turn off when the time control chip is at an initialized state;
- and
- wherein the enabling control module controls the logic control module to turn on to receive the modulating data provided by the time control chip when the time control chip is at a state after the initialized state is finished.
A method of driving a display panel, applying on a driving circuit for the display panel, wherein the driving circuit comprises:
