Abstract
The invention discloses a sensing substrate, which comprises a base and a sensing layer laid on one side of the base, wherein the sensing layer comprises a plurality of electrode units which are arranged as matrixes in a plurality of rows and lines. The sensing substrate can be used in a large-size capacitive touch screen and has good resolution ratio.
Description
Technical field
The present invention relates to a kind of induction substrate, especially a kind of induction substrate that is applied to large size capacitive touch screen.
Background technology
Along with science and technology development, touch-screen has replaced the mechanical type push button panel gradually becomes the new operation interfaces of electronic equipment such as mobile phone, notebook.Touch-screen comprises resistive touch screen, infrared touch panel, capacitive touch screen, and they obtain coordinate by different modes, and capacitive touch screen is because its transmittance, sharpness and better reliability, and is applied in the increasing product.
An important component part of capacitive touch screen is the induction substrate, and initial induction substrate mostly comprises substrate and two-layer inductive layer, and wherein a kind of inductive layer is laid on the bilateral of substrate, and wherein an inductive layer is the X-axis detection layers, and another inductive layer is the Y-axis detection layers.Another kind of is the same side that two-layer inductive layer all is laid on substrate, for fear of the mutual conduction between the electrode, bridge contact is set on glass substrate.The induction substrate of two kinds of capacitive touch screens all needs to lay two-layer inductive layer, complex structure, and cost is higher.People have invented the induction substrate that only has the individual layer inductive layer gradually, described individual layer inductive layer only have a delegation or a row touch-control electrode, this individual layer inductive layer can only be applied to undersized capacitive touch screen, can not be applied to large-sized capacitive touch screen.
Summary of the invention
Technical matters to be solved by this invention provides a kind of induction substrate that is applied to large size capacitive touch screen.
In order to address the above problem, the invention provides a kind of inductive layer that substrate comprises substrate and is layed in substrate one side of responding to, described inductive layer comprises a plurality of electrode groups, described electrode group is arranged in matrix with the form of several rows and some row.
Compared with prior art, the electrode group in the induction substrate of the present invention is arranged in matrix with the form of row and column, can be applied to large-sized capacitive touch screen, and has good resolution.
