Abstract: An exemplary embodiment of the present invention discloses a voltage generation circuit of a display apparatus, including at least one resistor, a memory configured to store a resistance value set signal, a controller changing a resistance value of the resistor referring to the resistance value set stored in the memory, and a voltage generator connected to one end of the resistor and is configured to receive an input current corresponding to the resistance value of the resistor and generate a gate-on voltage corresponding to the input current.

Abstract: Provided is a timing controller configured to operate a display device. The timing controller includes a receiving unit receiving a still image signal; a transmitting unit outputting an output data used to display images; a clock frequency spreader generating a spread clock signal having a frequency value adjusted between first and second frequency values by modulating a reference clock signal; a memory system storing a first image data which corresponds to a first frame of an image, and outputting the first image data in response to the spread clock signal; and a still image managing unit communicating with the memory system in order to output the first image data as the output data. According to the timing controller, electro-magnetic interference may be reduced and operation errors of the display device may be prevented.
