A data transmission method applied in a display, which includes a display panel, is provided. The data transmission method includes the following steps of: providing a host controller and n display drivers, n is a natural number greater than 1; providing a communication link under mobile industry processor interface (MIPI), connecting the host controller to the n display drivers; determining n virtual channel values Vc-Vcn corresponding to the respective n display drivers; employing the host controller for providing a command with a virtual channel parameter through the communication link under MIPI; when the virtual channel parameter corresponds to an ivirtual channel values Vci, an idisplay driver executing corresponding operations in response to the command, while the rest n&#x2212;1 display drivers ignoring the command, wherein i is a natural number smaller than or equal to n.

Data transmission method and display driving system

A display apparatus including a display panel, a display driver, a controller and an external circuit is introduced. The display drive includes a power circuit that supplies a first voltage and a second voltage to the display panel to sense a plurality of sensing currents flowing through the display panel according to the first voltage and the second voltage in a first operating mode. The display driver receives the plurality of sensing currents and a target current from the display panel in the first operating mode. The controller is coupled to the display driver and configured to determine a plurality of offsets according to the plurality of sensing currents and the target current in the first operating mode. The external memory is coupled to the controller and the display driver to store the offsets in the first operating mode. The display driver and a method adapted to a display apparatus are also introduced.
