AI Technical Summary

Technical Problem

Existing touch panels face challenges with detection sensitivity due to noise interference from close proximity of electrodes and wiring, leading to decreased sensitivity and a need for thinner, lighter, and more reliable designs that can be bent.

Method used

A touch panel configuration with conductive layers and light-emitting elements arranged to overlap and separated by insulating layers, using low-resistance materials and specific CR values to reduce noise and enable flexible designs.

Benefits of technology

Improves detection sensitivity, allows for thinner and lighter touch panels with reduced noise interference, and enables flexible and reliable operation.

Abstract

To improve the detection sensitivity of the touch panel, or to provide a thinner touch panel. To do so. Or, to provide a bendable touch panel. Or, a lightweight touch panel. Provide. [Solution] A display element and a capacitive element constituting a touch sensor are provided between a pair of substrates. The configuration is as follows. Furthermore, each of the pair of conductive layers constituting the capacitive element has an opening. This is preferable. Furthermore, the opening and the display element are arranged to overlap each other. A light-shielding layer is provided between a pair of conductive layers constituting the capacitive element and the substrate on the display side. do.
