Abstract
A method of driving a display by communicating with a controller through a first channel and a second channel includes; generating recovery data from a signal received through the first channel during a frame data period, detecting a vertical blank period between frame data periods, checking a training trigger event history during the vertical blank period, and during the vertical blank period, transmitting a training request direct to the first channel through the second channel when there is a training trigger event history.
Claims20
A data line driving circuit configured to communicate with a controller through a first channel and a second channel, the data line driving circuit comprising:
- a control circuit comprising a register configured to store training trigger event information associated with a training trigger event, detect a vertical blank period between frame data periods, and transmit a training request directed to the first channel through the second channel during the vertical blank period in response to the training trigger event information;
- and
- a synchronization circuit configured to generate a recovery clock signal synchronized with a training pattern received through the first channel during the vertical blank period, and generate recovery data from a signal received through the first channel in response to the recovery clock signal during a frame data period.
A display driving circuit comprising:
- a controller configured to transmit frame data through a first channel during a frame data period and transmit a training pattern through the first channel in response to a training request received through a second channel;
- and
- a data line driving circuit configured to detect a vertical blank period between frame data periods in response to a signal received from the controller and transmit the training request through the second channel during the vertical blank period.
A method of driving a display by communicating with a controller through a first channel and a second channel, the method comprising:
- generating recovery data from a signal received through the first channel during a frame data period;
- detecting a vertical blank period between frame data periods;
- checking a training trigger event history during the vertical blank period;
- and
- during the vertical blank period, transmitting a training request direct to the first channel through the second channel when there is a training trigger event history.
