Abstract
A data driver circuit is divided into a low potential region, an intermediate potential region, and a high potential region, and relative withstand voltages in the respective regions are set equal to each other. Both of the transmission of a power source voltage to the high potential region from the low potential region and the transmission of video signals are performed via the intermediate potential region. Due to such a constitution, the withstand voltages in the respective regions can be suppressed to low values.
Claims9
A display device comprising:
- a data driver circuit which outputs a low-potential-side analog video signal and a high-potential-side analog video signal generated in response to an inputted digital video signal to data lines from an output terminal which outputs the low-potential-side analog video signal and an output terminal which outputs the high-potential-side analog video signal;
- a first switch array which changes over the connection between the output terminal of the data driver circuit and the data lines;
- and
- a gate driver circuit which generates a gate voltage for sequentially selecting pixels arranged in a staggered manner for every 1 horizontal line and outputs the gate voltage to gate lines, wherein
- the data driver circuit supplies the analog video signal to the pixels on 1 vertical line among the pixels arranged in a staggered manner from the two neighboring data lines, and
- the data driver circuit is divided into a first region which generates the low-potential-side analog video signal, a second region which generates the high-potential-side analog video signal and a third region which generates an intermediate potential.
