Abstract: 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 Vc1-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 ith virtual channel values Vci, an ith display driver executing corresponding operations in response to the command, while the rest n−1 display drivers ignoring the command, wherein i is a natural number smaller than or equal to n.

Abstract: A driving apparatus of a display is disclosed. The driving apparatus includes a digital-to-analog converter (DAC) circuit, an output buffer circuit and a pre-charge circuit. The DAC circuit receives a display data with a digital format for generating a gray level voltage. The output buffer circuit is coupled to the DAC circuit, and has an output terminal to output an output signal. The output buffer circuit receives the gray level voltage and the output signal, and compares the gray level voltage and the output signal to generate a comparison result. The pre-charge circuit is coupled to the output buffer circuit, and generates a pre-charge output signal to the output terminal of the output buffer circuit according to the comparison result and a pre-charge enable signal.
