Display driver circuit and method of transmitting data in a display driver circuit

A method of transferring data in a display driver circuit, the method comprising:

• transmitting a configuration field from a timing controller to a source driver, configuration data for controlling the source driver being written in the configuration field;
• transmitting, from the timing controller to the source driver, a pixel data field in which image data is written;
• transmitting, from the timing controller to the source driver, a waiting field which is assigned for the source driver to have a first time to receive and to store the image data;
• and
• transmitting, from the timing controller to the source driver, a horizontal blank field which is assigned for the source driver to drive a display panel based on the image data,
• the timing controller configured to randomize the image data in a scrambling mode and to transmit the scrambled image data to the source driver.

A display driver circuit, comprising:

• a timing controller configured to transmit first scrambled image data to a first channel, and to transmit second scrambled image data to a second channel;
• a plurality of source drivers coupled to the timing controller and configured to receive scrambled image data from the timing controller via a respective channel;
• a first source driver of the plurality of source drivers, the first source driver coupled to the first channel and configured to receive the first scrambled image data and de-scramble the image data;
• and
• a second source driver of the plurality of source drivers, the second source driver coupled to the second channel and configured to receive the second scrambled image data and de-scramble the image data.
