Touch panel and display device provided with same

摘要

The touch panel (1a) of the present invention includes a plurality of driver electrodes (2), a plurality of detection electrodes (3) that extend in the column direction, and a complementary electrode (4), which extends in the direction in which the driver electrodes extend, and which forms a parasitic capacitance that corresponds to capacitance components that are not affected during detection of an object to be detected that comes into contact with or approaches the detection surface among the parasitic capacitances formed in the gaps between the driver electrodes (2) and the detection electrodes (3), in the gap from the detection electrodes (3).

主权项

1. A touch panel having a touch panel region including a plurality of driver electrodes that extend in a row direction and a plurality of detection electrodes that extend in a column direction, the touch panel detecting that an object has come into contact with or approached a detection surface on the basis of a change in an amount of electrical charge induced on the detection electrodes when a drive signal is applied to each of the driver electrodes,
wherein a complementary electrode is disposed so as to extend along a direction in which the driver electrodes extend in the touch panel region or a region that is adjacent thereto, the complementary electrode forming along with the detection electrodes a capacitance substantially corresponding to a capacitance component that is not affected by a presence or absence of said object among capacitances formed between the driver electrodes and the detection electrodes, wherein, when the drive signal is applied to each of the driver electrodes, a complementary signal having a reverse phase in relation to the drive signal is applied to the complementary electrode, wherein the driver electrodes include a plurality of driver electrode parts interconnected by first bridge parts, wherein the detection electrodes include a plurality of detection electrode parts interconnected by second bridge parts, wherein the driver electrode parts and the detection electrode parts are in the same layer as each other, wherein the second bridge parts are in the same layer as the driver electrode parts and the detection electrode parts, and the first bridge parts are in a layer different from said layer, and wherein the complementary electrode is in the same layer as the first bridge parts.
