Flexible Touch Panel Device

Abstract

The invention provides a flexible touch panel device. The device comprises a flexible substrate, a transparent conductive layer with a piezoresistive characteristic, a conductive wiring layer and a soft printed circuit assembly. The transparent conductive layer with the piezoresistive characteristic is arranged on the upper surface of the flexible touch panel device and comprises multiple first sensing units and multiple second sensing units. Each first sensing unit is electrically connected to a first direction, and each second sensing unit is electrically connected to a second direction which is different to the first direction. The conductive layer is located on the upper surface of the flexible substrate and surrounds a transparent conductive layer with the piezoresistive characteristic and electrically connects a first and a second sensing unit. The flexible printed circuit component comprises a connecting line group, a driving nd detecting module and a control unit. A conductive line layer aand the driving and detecting module and a control unit are electically connected. The flexible touch panel device is used, in order to save cost and time of additionally installed piezoresistive sensors, and application of interal space in the device is more flexible.

Description

technical field [0001] The present invention relates to a flexible touch panel device, in particular to a flexible touch panel device with piezoresistive properties. Background technique [0002] Electronic devices with touch input functions have become mainstream in the consumer electronics market in recent years, and flexible electronic devices have attracted more attention because they are bendable and can be placed in different spaces. Touch panels can be divided into resistive, capacitive, infrared and ultrasonic according to their different sensing principles. To achieve the purpose of touch. [0003] However, the current flexible touch panels of flexible electronic devices generally only use capacitive sensing methods. If other sensors can be configured on the touch panel, there is an opportunity to greatly increase its added value , so in the background art there is a practice of attaching pressure or strain sensors to the touch panel. However, disposing the press...

[0003] However, the current flexible touch panels of flexible electronic devices generally only use capacitive sensing methods. If other sensors can be configured on the touch panel, there is an opportunity to greatly increase its added value , so there is a practice of attaching pressure or strain sensors to the touch panel in the background technology

However, setting the pressure / stress sensor on the touch panel will complicate the overall manufacturing process and increase the cost and time of the manufacturing process.
