Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] like figure 1 As shown, when a panel 101 with a finite thickness is subjected to pressure generated by a touch action, it will deform, and the amount of deformation depends on the physical size of the panel 101 , Young's modulus and so on. However, for a given touch screen, the degree of deformation of the panel 101 will only depend on the magnitude and location of the force applied to the panel surface. This deformation causes strain on the upper and lower surfaces of the panel 101, causing the upper surface to be compressed and the lower surface to be stretched. This strain is greatest n...

Abstract

The invention is applied to the field of touch technology and provides a touch screen pressure and position sensing method. The method includes: providing a substrate, and setting an electrode layer, provided with a plurality of mutually independent electrodes, on the substrate; setting a plurality of strain sensors, used for measuring surface deformation produced when the substrate is under pressure, on the substrate, and connecting the strain sensors to two different electrodes; allowing the conductive electrodes to convert deformation information detected by the sensors into electrical signals transmitted to a touch screen controller; allowing the touch screen controller to receive sensing information and convert the sensing information into touch coordinates transmitted to a processing unit, and allowing the processing unit to analyze and process the data. The invention further provides a touch screen pressure and position sensing element and an electronic touch device. Compared with the existing touch screen, the sensing method, the sensing element and the electronic touch device have the advantages that only one substrate needs to be provided with the integrated electrodes, the circuit is simple in design, integration is convenient, the cost is low, omission of an insulating layer decreases light loss and increases transparency of a touch screen.

Description

technical field [0001] The invention belongs to the technical field of touch sensing, and in particular relates to a touch screen pressure and position sensing method, a sensing element and an electronic touch device Background technique [0002] As an intuitive and simple input tool for computers or other data processing devices, touch screens are widely used in various mobile devices. There are many different types of touch sensing technologies, mainly including capacitive, resistive, infrared and surface acoustic wave, which can detect single or multiple touch locations. An ideal touch screen would be able to sense not only the location of the touch but also the pressure of the touch, which provides an additional degree of freedom for touch input and accommodates different input methods such as stylus, finger, and wearing Gloved fingers etc. Therefore, the touch sensing technology of pressure and position is also one of the research hotspots in this field.
