Abstract:
A drive circuit for driving a display device, comprising:a voltage level shift circuit which receives a control signal and a data signal each having a voltage level defined by a difference between a high-signal voltage and a low-signal voltage, and which increases the voltage level of the control signal and the data signal to output a voltage level shifted control signal and a voltage level shifted data signal; and an output circuit which receives the voltage level shifted data signal and which outputs an output data signal corresponding to the voltage level shifted data signal in response to the voltage level shifted control signal; wherein said output circuit outputs a plurality of the output data signals in parallel and comprises: a data store circuit which stores the voltage level shifted data signal to obtain a stored data signal, and which outputs the stored data signal in response to the voltage level shifted control signal; and an output driver which outputs the output data signals corresponding to the stored data signal.
