1. A display device to drive a plurality of display modules for dividing data signals comprising:
the plurality of display modules for displaying an image; a plurality of display module drivers for respectively driving the display modules; a data divider receiving data signals for displaying an image on the display device and separating the received data signals into output data signals corresponding to each respective display module driver; and a timing control signal generator for generating a timing control signal to be supplied commonly to the display module drivers, wherein the timing control signal generator modulates a vertical control signal, a horizontal control signal, a data enable signal and a data clock signal, wherein the data divider comprises a memory controller for controlling reading and writing operations of the memories, a switching unit for turning on or off such that the data signals are respectively stored in the memories and a decoder for controlling the switching unit such that the data signals are distributed in units of predetermined times in response to an externally generated data time-division control signal, wherein in the writing operation, the memory controller writes external data signals in the memories for the respective pixels of the plurality of display modules using the period of the data clock signal, wherein in the read operation, the memory controller performs a control operation of reading pixel data line by line and outputting a 1-line pixel data at a frequency corresponding to ½ of an input data clock signal. |
