Abstract
Disclosed are a display driving circuit and a display device. The display driving circuit includes an output buffer unit that outputs a pair of pixel signals, an output switch unit that directly transfers the pair of pixel signals to a pair of output lines or transfers the pair of pixel signals to the pair of output lines such that the pair of pixel signals cross each other in correspondence with repetitive panel charging/discharging periods, and a charge sharing switch unit that controls charge sharing of the pair of output lines in correspondence with a charge sharing period between the panel charging/discharging periods, and provides a variable connection resistance value for the charge sharing. Consequently, power consumption and heat generation of the display driving circuit are reduced.
