Touch sensor and touch panel device
A touch panel device in which a touch panel provided with a switch display and a touch sensor having a plurality of electrodes that include a chevron-shaped portion and a valley-shaped portion and that correspond to the switch display are disposed in a stacked manner, a slide input being capable of being performed by slide operation in an arrangement direction of the electrodes, in which, among intersection angles formed by intersection between a virtual line extending in the slide operation direction and a valley bottom of the valley-shaped portion, a valley side external angle that is an external angle of each electrode is larger than, among intersection angles formed by intersection between the virtual line and a peak portion of the chevron-shaped portion, a chevron side internal angle that is an internal angle of each electrode, and a buried portion that raises the valley bottom is provided in each electrode.
1. A touch panel device, comprising:
a touch panel provided with a switch display;
a touch sensor provided with a plurality of electrodes that include a chevron-shaped portion and a valley-shaped portion and that correspond to the switch display;
the touch panel and the touch sensor being disposed in a stacked manner; and
a slide input being capable of being performed by slide operation in an electrode arrangement direction, wherein
among intersection angles formed by intersection between a virtual line extending in the slide operation direction and a valley bottom of the valley-shaped portion, a valley side external angle B that is an external angle of each electrode is larger than, among intersection angles formed by intersection between the virtual line and a peak portion of the chevron-shaped portion, a chevron side internal angle A that is an internal angle of each electrode.
2. The touch panel device according to claim 1 , wherein
a buried portion that raises the valley bottom of the valley-shaped portion is provided in each electrode.
3. The touch panel device according to claim 1 , wherein
a filling portion that shortens a distance in the slide operation direction from a peak portion of an adjacent electrode is provided in an outer edge forming the chevron-shaped portion or the valley-shaped portion of each electrode.
4. The touch panel device according to claim 1 , wherein
the valley side external angle B is substantially rectangular.
5. A touch panel device according to claim 1 , wherein
the touch panel and the touch sensor are formed of a same resin film and are integral with respect to each other.
6. A touch sensor comprising:
a plurality of electrodes including a chevron-shaped portion and a valley-shaped portion, a slide input being capable of being performed by slide operation in an arrangement direction of the plurality of electrodes, wherein
among intersection angles formed by intersection between a virtual line extending in the slide operation direction and a valley bottom of the valley-shaped portion, a valley side external angle B that is an external angle of each electrode is larger than, among intersection angles formed by intersection between the virtual line and a peak portion of the chevron-shaped portion, a chevron side internal angle A that is an internal angle of each electrode.
