摘要： The present invention discloses a method for a source driver, for preventing image sticking in a display panel coupled to the source driver. The source driver includes a first output driver and a second output driver having different polarities. The first output driver is configured with a first driving capability and the second output driver is configured with a second driving capability. The method includes the steps of: obtaining an effective voltage of a pixel in the display panel; and adjusting the second driving capability of the second output driver to be identical to the first driving capability of the first output driver, to allow the adjusted second driving capability to drive the effective voltage to reach a level having the same magnitude as a level of the effective voltage driven by the first source driver with the same variation of display data.

摘要： 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 and enter a swing boost mode when quality of data signal is detected to be deteriorated in the normal mode. In the swing boost mode, the control circuit boosts the swing of the data signal to be higher than a normal level of the data signal in the normal mode.

摘要： 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.

摘要： A display panel includes a substrate, a chip, a connecting portion, and a plurality of connecting lines. The substrate includes an active area where a pixel array is located and a peripheral area at a side of the active area. The peripheral area includes a chip region and a connecting region. The chip is mounted on the chip region of the peripheral area and electrically connected to the pixel array. The connecting portion is disposed on the connecting region of the peripheral area and configured to electrically connect a flexible printed circuit (FPC) board. The connecting region is overlapped with an extensional region extended from the chip region along a longitudinal axis of the chip. The connecting lines are electrically connecting the chip and the connecting portion.
