Problems solved by technology

[0002] With the development of electronic technology, ordinary keyboard or button operation can no longer meet people's needs
Under the trend of growing and developing touch screen technology in the application of man-machine input interface, the traditional resistive touch screen has been gradually replaced by capacitive touch screen due to its easy aging, short service life, and inability to adapt to the application of home appliances, vehicles and other industrial instruments. Instead, the existing capacitive-sensing touch screen has a complex mechanism and a single function, does not have the functions of continuous handwriting and multi-point input, and the scope of use is limited

Embodiment Construction

[0015] refer to figure 1 , figure 2 , a non-contact capacitive sensing touch screen, comprising a substrate glass 1, one surface of the substrate glass 1 is coated with a horizontally connected mesh Y-direction ITO electrode matrix 2, the Y-direction ITO electrode matrix is ​​coated with an insulating layer 3, and the insulating layer 3 is coated with There is a matrix of X-direction ITO electrodes 4 that is roughly complementary in shape to the blank part of the grid-shaped Y-direction ITO electrode 2 matrix, and is vertically connected. The leads of the Y-direction ITO electrode 2 matrix and the X-direction ITO electrode 4 matrix extend to the edge of the substrate glass 1 .

[0016] As a further improvement of the present invention, the X-direction ITO electrode 4 matrix is ​​coated with a protective film 5, which can be coated with high hardness and corrosion-resistant materials in special cases to adapt to different application environments. The insulating layer 3 is mad...

Abstract

The invention discloses a non-contact capacitance induction touch screen, including a baseplate glass. One surface of the baseplate glass is plated by a horizontally connected ITO electrode matrix along the reticular Y direction; the ITO electrode matrix along the reticular Y direction is plated by an insulating layer; the insulating layer is plated by a longitudinally connected ITO electrode matrix along the X direction which is approximately complemented with the blank part of the ITO electrode matrix along the reticular Y direction. The non-contact capacitance induction touch screen provided by the invention, with built-in double-layer ITO design and an additional control processor, can achieve continuous hand-writing simulation control and operation. With no wear and tear, long service life, high luminousness, small thickness, low cost and easy operation, the touch screen can be rapidly applied to various screens of high-end and low-end electronic products of all sizes and all types, thus facilitating humanized design and industrial output.

Description

technical field [0001] The invention relates to a capacitive sensing touch screen, in particular to a non-contact capacitive sensing touch screen capable of continuous handwriting with multi-point input. Background technique [0002] With the development of electronic technology, ordinary keyboard or key-type operations can no longer meet people's needs. Under the trend of growing and developing touch screen technology in the application of man-machine input interface, the traditional resistive touch screen has been gradually replaced by capacitive touch screen due to its easy aging, short service life, and inability to adapt to the application of home appliances, vehicles and other industrial instruments. Instead, the existing capacitive-sensing touch screen has complex mechanisms and relatively single functions, does not have the functions of continuous handwriting and multi-point input, and its scope of use is limited. Contents of the invention [0003] In order to ove...
