Abstract
An image display apparatus comprises: a display panel; a row wiring drive circuit; and a column wiring drive circuit, wherein, the row wiring drive circuit includes: a selection signal output circuit which outputs a selection signal to a row wiring to be set to a selected state; a non-selection signal output circuit which outputs a non-selection signal to a row wiring to be set to a non-selected state; and an adjustment circuit which decreases an output impedance of the non-selection signal output circuit by feeding back a potential corresponding to a potential of the row wiring in the non-selected state.
Claims7
An image display apparatus, comprising:
- display panel on which a plurality of display elements are disposed in a matrix using a plurality of row wirings and a plurality of column wirings;
- a row wiring drive circuit which sequentially selects a plurality of row wirings;
- and
- a column wiring drive circuit which outputs modulation signal, obtained by modulation based on a video signal being input, to the plurality of column wirings, wherein
- the row wiring drive circuit includes:
- a selection signal output circuit which outputs a selection signal to a row wiring to be set to a selected state;
- a non-selection signal output circuit which outputs a non-selection signal to a row wiring to be set to a non-selected state;
- and
- an adjustment circuit which decreases an output impedance of the non-selection signal output circuit by feeding back a potential corresponding to a potential of the row wiring in the non-selected state.
