Abstract
A drive circuit for a display device includes one or more data channel units, a first and second capacitors, and a comparison unit. The data channel unit includes a data channel, a judgment unit, a logic operation unit, a first control switch and a second control switch. The first control switch is connected to the output end of the data channel and one end of the first capacitor which is connected to the comparison unit. The second control switch is connected to the output end of the data channel and one end of the second capacitor which is connected to the first capacitor. Two output terminals of the logic operation unit are configured to output first and second switch control signals to control the switching of the first and second control switches.
