Display system and operating method thereof

1. A display system, comprising:

a display panel;

a source driver coupled to the display panel and configured to provide a plurality of pixel voltages to the display panel; and

a timing controller comprising a transmission interface circuit and coupled to the source driver, wherein,

the timing controller detects whether an operation timing of the display system enters a vertical blanking (VBK) period;

in response to the operation timing of the display system entering the VBK period, the timing controller turns off the transmission interface circuit and causes the source driver to enter an idle mode; and

in response to the operation timing of the display system being at a preset time before an end of the VBK period, the timing controller turns on the transmission interface circuit and wakes up the source driver.

2. The display system of claim 1 , wherein,

in response to the timing controller turning on the transmission interface circuit, the transmission interface circuit outputs a training code to the source driver; and

in response to the source driver locking a transmission timing based on the training code, a lock signal is set to an enabled level, wherein the lock signal is provided to the timing controller.

3. The display system of claim 2 , wherein, in response to the lock signal being at the enabled level, the timing controller sequentially transmits a setting parameter and display data to the source driver through the transmission interface circuit, and the source driver provides the plurality of pixel voltages based on the display data.

4. The display system of claim 3 , wherein, during the VBK period, the lock signal is set to a disabled level.

5. The display system of claim 1 , wherein, the timing controller outputs a wake-up signal to the source driver, and sets the wake-up signal to an enabled level to wake up the source driver.

6. The display system of claim 5 , wherein, during the VBK period, the wake-up signal is set to a disabled level to cause the source driver to enter the idle mode.

7. An operating method of a display system, comprising:

detecting whether an operation timing of the display system enters a VBK period via a timing controller of the display system;

turning off a transmission interface circuit in the timing controller via the timing controller and causing a source driver of the display system to enter an idle mode in response to the operation timing of the display system entering the VBK period; and

turning on the transmission interface circuit via the timing controller and waking up the source driver in response to the operation timing of the display system being at a preset time before an end of the VBK period.

8. The operating method of claim 7 , further comprising:

outputting a training code to the source driver via the transmission interface circuit in response to the timing controller turning on the transmission interface circuit; and

setting a lock signal to an enabled level via the source driver in response to the source driver locking a transmission timing based on the training code, wherein the lock signal is provided to the timing controller.

9. The operating method of claim 8 , further comprising:

transmitting sequentially a setting parameter and display data to the source driver through the transmission interface circuit via the timing controller in response to the lock signal being at the enabled level, wherein, the source driver provides a plurality of pixel voltages to a display panel of the display system based on the display data.

10. The operating method of claim 8 , further comprising:

setting the lock signal to a disabled level via the source driver during the VBK period.

11. The operating method of claim 7 , further comprising:

outputting a wake-up signal to the source driver via the timing controller; and

setting the wake-up signal to an enabled level via the timing controller to wake up the source driver.

12. The operating method of claim 11 , further comprising:

setting the wake-up signal to a disabled level via the timing controller to cause the source driver to enter the idle mode during the VBK period.
