TOUCH PANEL, DISPLAY PANEL, AND DISPLAY UNIT

摘要

A touch panel, a display panel, and a display unit achieving prevention of erroneous detection caused by external noise, are provided. The touch panel includes: a plurality of detection scan electrodes extending in a first direction; and a plurality of detection electrodes facing the plurality of detection scan electrodes and extending in a second direction which intersects the first direction. A ratio of fringe capacitance to total capacitance between one or more selected detection scan electrodes and a first detection electrode is different from a ratio of fringe capacitance to total capacitance between the one or more selected detection scan electrodes and a second detection electrode. The one or more selected detection scan electrodes are selected, in a desired unit, from the plurality of detection scan electrodes, to be supplied with a selection pulse, and each of the first and the second detection electrodes is selected from the plurality of detection electrodes.

主权项

1. A touch panel comprising:
a scan-side substrate; a detection-side substrate; scan electrodes on the scan-side substrate and extending in parallel along a first direction, each scan electrode being an electrode to which a selection drive voltage is applied; and detection electrodes facing the scan electrodes and extending in parallel along a second direction which intersects the first direction, each detection electrode being an electrode from which a detection output signal is obtained, the detection electrodes being disposed on the detection-side substrate, wherein,
one or more selected scan electrodes are selected, in a desired unit, from the scan electrodes by the application of the selection drive voltage, andshapes the scan electrodes or shapes of the detection electrode vary according to their positions.
