Abstract
A display driving device is disclosed. The display driving device includes: a data signal end for providing a data signal, a source line, and a switching circuit. The source line can transmit the data signal to a first pixel circuit and a second pixel circuit. Along a direction of the source line, a distance between the second pixel circuit and the data signal end is larger than a distance between the first pixel circuit and the data signal end. The switching circuit is between the data signal end and the source line, and can be turned on in response to a first control signal, and can be turned on in response to a second control signal. A turned-on time period of the switching circuit in response to the second control signal is longer than a turned-on time period of the switching circuit in response to the first control signal.
