Multi-element inductive touch pad

Abstract

The invention relates to a multi-element inductive touch pad, which comprises a protective layer, a first axial line trace layer, an insulating layer, a multi-element inductive layer, a separating ball layer, a conducting film and a base plate in turn, wherein the first axial line trace layer and the multi-element inductive layer are respectively provided with a first axial line trace and a second axial line trace crossed with each other and conducting circuits connecting the line traces for transmitting an inductive signal to a subsequent signal processing component; besides, the end of the second axial line trace and the conducting film are provided with electric nodes and are electrically connected with a voltage source and a resistance calculation circuit for generating and calculating the inductive signal during pressing.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a multi-sensor touch panel structure which has the advantages of both resistive and capacitive touch panels and simultaneously simplifies the number of sensing layers. Background technique [0002] With the continuous introduction of portable and interactive electronic products, a touch pad has almost become a common pointer tool for this type of electronic products. Under the urging of the market demand, the production quality and performance of the touch panel are also continuously improved. With the sharp drop in price and the increase in output, the touch panel is widely used in various electronic products. Generally speaking, the structure of the touch panel can be divided into four types due to different application principles: resistive touch panel, capacitive touch panel, acoustic touch panel and optical touch panel. Also because the application principles of these touc...

Problems solved by technology

However, although this creation can achieve the above-mentioned combination of the resistive and capacitive touch panel structures and achieve the desired purpose and effect, this creation is still only a superposition combination of the two structures, and does not Zhen thinks about how to effectively simplify the structure, reduce the size and reduce the cost. Therefore, it takes a lot of manufacturing and assembly costs to form the composite touch panel. Not only the components are more complicated, but the volume and control of the touch panel The number of components has also doubled; at the same time, the resulting high unit price of the touch panel will also greatly reduce its market acceptance
