Abstract: The present disclosure discloses a display driving device capable of reducing a chip area and a data transmission time and a display device including the same. The display driving device includes a first source driver and a second source driver. Each of the first source driver and the second source driver may include a sensing circuit configured to sample and hold input signals of a multi-channel, a multiplexer configured to transmit the input signals held by the sensing circuit, an analog-to-digital converter configured to convert, into digital data, the input signals received from the multiplexer, and a transmission circuit configured to transmit the digital data to a timing controller through a bus lane. The sensing circuit of the second source driver may hold the input signals while the first source driver transmits the digital data.
