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: The disclosure provides a method for driving an OLED touch-and-display device, a driving circuit, and the OLED touch-and-display device. The method includes: dividing each display frame into at least one display period and at least one touch detection period which are alternated; during each display period, generating sequentially-shifted gate driving signals and sequentially-shifted light-emission control signals, and sequentially applying them to at least a part of gate driving lines of the plurality and corresponding light-emission control lines; during each touch detection period: suspending the generation of gate driving signals or also suspending the generation of light-emission control signals; adjusting the average display luminance of a plurality of rows of pixels within a predetermined time period, so that the display luminance is uniform, and the gate driving signal for each row of pixels and the light-emission control signal of the light-emission control line maintain a preset timing relationship.

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.
