Abstract
In a display device including a driver that drives a load line of an electro-optical panel through capacitor charge redistribution, a data voltage will change in the case where an electro-optical panel-side capacitance changes, even when tone data is the same. Accordingly, by detecting a voltage at a data voltage output terminal, a connection state and outputs between the data voltage output terminal and the electro-optical panel can be detected.
Claims20
A driver comprising:
- a capacitor driving circuit that outputs first to nth capacitor driving voltages (where n is a natural number of 2 or more) corresponding to tone data to first to nth capacitor driving nodes;
- a capacitor circuit including first to nth capacitors provided between the first to nth capacitor driving nodes and a data voltage output terminal;
- and
- a detection circuit that carries out a first detection that detects a connection state between the data voltage output terminal and an electro-optical panel.
