Claims18
A method performed by a display device comprising a display panel, a data driving device for driving the display panel, and a data processing device for transmitting image data to the data driving device, the method comprising:
- transmitting, from the data processing device to the data driving device, a communication signal which includes a training clock pattern for performing a first clock training in each of one or more of a plurality of time intervals,
- wherein the first clock training is performed in each of said one or more of the plurality of time intervals before a second clock training is performed, and
- wherein the second clock training is performed after the plurality of time intervals;
- and
- after transmitting, from the data processing device to the data driving device, the communication signal including a training clock pattern, determining, by the data driving device, a result of the first clock training performed in each of said one or more of the plurality of time intervals,
- wherein each of said one or more of the plurality of time intervals is associated with a control value that is for determining a configuration for performing the first clock training in each of said one or more of the plurality of time intervals.
A display device comprising:
- a display panel;
- a data driving device for driving the display panel;
- and
- a data processing device for transmitting image data to the data driving device,
- wherein the display device is configured to:
- transmit, from the data processing device to the data driving device, a communication signal which includes a training clock pattern for performing a first clock training in each of one or more of a plurality of time intervals,
- wherein the first clock training is performed in each of said one or more of the plurality of time intervals before a second clock training is performed, and
- wherein the second clock training is performed after the plurality of time intervals;
- and
- after transmitting, from the data processing device to the data driving device, the communication signal including a training clock pattern, determine, by the data driving device, a result of the first clock training performed in each of said one or more of the plurality of time intervals, and
- wherein each of said one or more of the plurality of time intervals is associated with a control value that is for determining a configuration for performing the first clock training in each of said one or more of the plurality of time intervals.
A method performed by a data driving device for receiving image data from a data processing device and for driving a display panel, the method comprising:
- receiving, from the data processing device, a communication signal including a training clock pattern for performing a first clock training in each of one or more of a plurality of time intervals,
- wherein the first clock training is performed in each of said one or more of the plurality of time intervals before a second clock training is performed, and
- wherein the second clock training is performed after the plurality of time intervals;
- and
- after receiving, from the data processing device, the communication signal including a training clock pattern, determining a result of the first clock training performed in each of said one or more of the plurality of time intervals,
- wherein each of said one or more of the plurality of time intervals is associated with a control value that is for determining a configuration for performing the first clock training in each of said one or more of the plurality of time intervals.
