    Abstract: The disclosure is directed to a timing controller having a mechanism for frame synchronization, a display panel having the timing controller thereof, and a display system having the timing controller thereof. According to an aspect of the disclosure, the disclosure provides an integrated circuit which includes a timing controller to transmit a first TE signal to an application processor and receive a first image frame from the application processor after the application processor receives the first TE signal, and a control circuit to generate a first sync signal when the timing controller receives the first image frame, wherein when the application processor receives a second TE signal and the application processor is not ready to transmit a second image frame to the timing controller, the control circuit delays a first waiting period to generate a second sync signal.

    Abstract: A display device, a display driving integrated circuit (DDIC), and an operation method are provided. The display device includes a display panel, a first DDIC, and a second DDIC. The first DDIC generates a display synchronization signal, and drives a first display area of a display panel according to the display synchronization signal. The second DDIC is coupled to the first DDIC to receive the display synchronization signal. The second DDIC performs a frequency tracking operation on an internal clock signal of the second DDIC by selectively using the display synchronization signal. The second DDIC drives a second display area of the display panel according to the internal clock signal and the display synchronization signal.

    Abstract: A driving circuit and a synchronization method thereof for a multi-panel display device are provided. The driving circuit includes a first driving chip and a second driving chip which share a power circuit. One of the first driving chip and the second driving chip is set as a master driving chip or a slave driving chip based on a control signal. The master driving chip transmits a power enable signal and a control signal to the power circuit, which triggers the power circuit providing power voltages to the master driving chip and the slave driving chip. When the master driving chip transmits a timing control signal to the slave driving chip, the slave driving chip performs a power synchronization operation to synchronize with the master driving chip based on the timing control signal.

    Abstract: A data transmission system is utilized in a Mobile Industry Processor Interface (MIPI). A master device includes a control module for generating a control signal according to a feedback signal. A packet encoding module is coupled to the control module for encoding an original packet to be a transmission packet according to the original packet and the control signal to process a transmission operation. A slave device includes a packet decoding module for decoding the transmission packet to be the original packet or a related display device signal corresponding to the original packet to a display device. A feedback module is coupled to the packet decoding module for generating the feedback signal to the control module of the master device according to a decoding condition of the control module, so as to switch a transmission mode of the transmission operation.
