Title:
Display device
Document Type and Number:
Japanese Patent JP6255179
Kind Code:
B2
Abstract:
In a capacitive touch panel, edge regions of the panel display generally have poor accuracy of coordinate detection of a touch point as compared to the intermediate region of the panel display. A display device includes a plurality of first electrodes arranged at predetermined pitches and extending in a X-direction; and a plurality of second electrodes arranged at predetermined pitches and extending in a Y-direction, wherein both endmost first electrodes of the plurality of first electrodes have a smaller pitch than the other first electrodes, both endmost second electrodes of the plurality of second electrodes have a smaller pitch than the other second electrodes, and the display device is configured to detect a touch based on a capacitance variation at one or more of intersections of the plurality of first electrodes with the plurality of second electrodes.
