Abstract
A display device is provided and includes display panel; sensor substrate formed on display panel; and M drive electrodes and detection electrodes extended in direction so as to intersect with M drive electrodes, wherein among M drive electrodes, any of lengths of N first drive electrodes, which are continuously adjacent to one another, is shorter than any of lengths of other N second drive electrodes which are continuously adjacent to one another, and number of detection electrodes which intersect with N first drive electrodes is larger than number of detection electrodes which intersect with N second drive electrodes.
Claims4
A display device comprising:
- a display panel;
- a sensor substrate formed on the display panel;
- and
- M drive electrodes (where M represents an integer larger than one) and a plurality of detection electrodes extended in a direction so as to intersect with the M drive electrodes on the sensor substrate,
- wherein among the M drive electrodes, any of the lengths of N first drive electrodes (where N represents an integer larger than one), which are continuously adjacent to one another, is shorter than any of the lengths of the other N second drive electrodes which are continuously adjacent to one another, and the N first drive electrodes include at least two groups each of more than one first drive electrodes,
- wherein the number of detection electrodes which intersect with the N first drive electrodes is larger than the number of detection electrodes which intersect with the N second drive electrodes,
- wherein the N second drive electrodes are provided between the at least two groups of N first drive electrodes,
- wherein a spacing between electrodes at the N first drive electrodes is substantially equal to a spacing between electrodes at the N second drive electrodes, and
- wherein a spacing of the plurality of detection electrodes intersecting the N first drive electrodes is substantially equal to the spacing of the plurality of detection electrodes intersecting the N second drive electrodes.
