Abstract

The present invention relates to a controller, a source driver integrated circuit (IC), a display device, and a signal transmission method thereof. To provide a display device and a method for signal transmission in a display device, which are able to provide sensing data to the controller in a synchronized manner to allow the controller to recognize the sensing data reliable a display device is provided comprising: display panel (110) having data lines (DL) and gate lines (GL), wherein subpixels are disposed at intersections of the data lines (DL) and gate lines (GL); at least one source driver integrated circuit (SDIC) for supplying data signals to the data lines (DL) and receiving sensing data from a subpixel; at least one gate driver integrated circuit (GDIC) for supplying scanning signals to the gate lines (GL); a controller (140) for controlling the source driver IC (SDIC #k) and the gate driver IC (GDIC); an analog/digital converter, ADC, for receiving the sensing data of the subpixel and for converting the sensing data to a digital data and outputting the digital data to the controller (140), wherein the controller (140) is adapted to provide timing information to the source driver IC (SDIC) for adjusting in the source driver IC the timing for outputting of the digital data to the controller (140), and wherein the controller (140) is adapted to perform a compensation based on the received digital data.
