Timing controller and operation method thereof
First Claim
1. A timing controller, comprising:
- a transmitter circuit, transmitting a data signal to a source driving circuit; and
a control circuit, controlling the transmitter circuit to adjust a swing of the data signal, whereinin a condition that the control circuit is operated in a normal mode, the control circuit ends the normal mode to enter a swing boost mode when a lock signal fed back by the source driving circuit indicates that quality of the data signal is deteriorated,the control circuit controls the transmitter circuit to boost the swing of the data signal from a normal level to a high level in the swing boost mode,in a condition that the control circuit is operated in the swing boost mode, the control circuit enters a clock training mode when the lock signal fed back by the source driving circuit indicates that the data signal has loss of lock, andthe control circuit controls the transmitter circuit to employ a clock training data string as the data signal to transmit to the source driving circuit in the clock training mode.

Abstract
A timing controller and an operation method thereof are provided. The timing controller includes a transmitter circuit and a control circuit. The control circuit ends a normal mode to enter a swing boost mode when a lock signal fed back by a source driving circuit indicates that quality of data signal is deteriorated in the normal mode. In the swing boost mode, the control circuit controls the transmitter circuit to boost the swing of the data signal from a normal level to a high level. The control circuit ends the swing boost mode and enters a clock training mode when the source driving circuit causes loss of lock to the data signal in the swing boost mode. In the clock training mode, the control circuit controls the transmitter circuit to employ a clock training data string as the data signal to transmit to the source driving circuit.

9. An operation method of a timing controller, comprising:
-
transmitting a data signal to a source driving circuit by a transmitter circuit; in a condition that the timing controller is operated in a normal mode, ending the normal mode to enter a swing boost mode when a lock signal fed back by the source driving circuit indicates that the quality of the data signal is deteriorated; boosting a swing of the data signal from a normal level to a high level by the transmitter circuit in the swing boost mode; in a condition that the timing controller is operated in the swing boost mode, entering a clock training mode when the lock signal fed back by the source driving circuit indicates that the data signal has loss of lock; and employing a clock training data string as the data signal to transmit to the source driving circuit by the transmitter circuit in the clock training mode. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
