Abstract
An embodiment provides a display panel drive device that receives image data in a plurality of image reception periods within one frame period and retrains a data link according to link data received in an interval between the image reception periods.
Claims16
A data drive device in a display device, the data drive device comprising:
- a data reception circuit configured to train a communication clock according to a received clock pattern, to receive first link data in accordance with the communication clock, to train a data link according to the first link data, to receive image data in a plurality of image reception periods within one frame period, to sort the image data in accordance with the data link, to receive second link data in a link reception period disposed between the plurality of image reception periods, and to retrain the data link according to the second link data;
- and
- a data voltage drive circuit configured to generate a data voltage by converting the image data and to supply the data voltage to each sub-pixel.
A data processing device comprising:
- a data processor configured to encode image data;
- and
- a data transmitter configured to transmit a clock pattern, to transmit first link data, to transmit the image data in a plurality of image transmission periods within one frame period, to transmit second link data in a link transmission period disposed between the plurality of image transmission periods, and to retransmit the clock pattern and the first link data when a state of a received lock signal is changed.
A display drive system comprising:
- a data processing device configured to transmit a clock pattern, to transmit first link data, to transmit image data in a plurality of image transmission periods within one frame period, and to transmit second link data in a link transmission period disposed between the image transmission periods;
- and
- a data drive device configured to train a communication clock according to the received clock pattern, to receive the first link data in accordance with the communication clock, to train a data link according to the first link data, to receive the image data in a plurality of image reception periods, to sort the image data in accordance with the data link, to receive the second link data in a link reception period disposed between the plurality of image reception periods, and to retrain the data link according to the second link data.
