Display driving circuit and display device having the same

The display driving circuit includes first through (2 * n) in the buffer, the buffer controller, and the first to n-th image processing unit and the source driver. The buffer controller is first from the first buffer every hour, the (2 * n) in the order of the buffer the first to the (2 * n) buffers circulation either by selecting and the selected pixel data is received for an hour in the It is stored in the buffer. First to n-th image processing unit each of the case which are respectively connected to the two buffer among the first to the (2 * n) buffer and the pixel data are stored in the corresponding buffer, corresponding to n times the first time performing signal processing for the time the pixel data stored in the corresponding buffer, while to produce the respective processed data. Source driving unit generates an analog signal based on the processed data provided from the first to the n image processing sections. A display driving circuit to improve the EMI characteristics and reduce the power consumption.
