Description
Technical field
The utility model relates to touch-screen, belongs to field of display elements.
Background technology
Touch-screen is as a kind of interface tool by the display screen operation, allow the user directly to touch or hand-written mode input message by point on the display device surface that is provided with touch-screen, friendly interface, convenience, therefore be used in more and more widely on the various portable sets, such as mobile phone, panel computer etc.
According to the difference of contact type and affirmation contact point mode, touch-screen can be divided into resistance-type, condenser type, infrared type etc.Along with the maturation of capacitive touch screen control IC technology and the decline of cost, the application of capacitive touch screen is more and more extensive.Common capacitive touch screen is surface capacitance type touch screen and internal-surface capacitive touch screen exceptionally, and internal-surface capacitive touch screen weares and teares when touch control operation less because do not have air to have higher transmittance between layers, and serviceable life is longer.
Existing touch-screen easily is subjected to the impact of extraneous electric condition serviceable life because reasons in structure is difficult to overcome interference and the short circuit problem between the electrode usually.
The utility model content
For the defective of prior art, the utility model provides a kind of touch-screen of architecture advances, has a link cost low, occupies little space, and antijamming capability is good, touches accurate characteristics.
For achieving the above object, the utility model is achieved through the following technical solutions:
Internal-surface capacitive touch screen comprises the first glass substrate, is formed at the first conductive electrode of the first glass substrate inside surface; The second glass substrate is formed at the second conductive electrode of the second glass substrate inside surface; Wherein the first conductive electrode is positive electrode layer, and the second conductive electrode is positive electrode layer, and the first conductive electrode is connected with wire at the different product ends of glass substrate respectively with the second conductive electrode.
Wherein, can two glass substrates be accomplished together by various ways such as pressing or welding or screws, preferred, be bonded together with glue between described the first conductive electrode and the second conductive electrode, this mode is simple and fast more.
Wherein, the first conductive electrode and the second conductive electrode can realize with any type, and preferred, described the first conductive electrode and the second conductive electrode are transparent conductive film, for example oxidation steel tin (ITO) or oxidation steel zinc (IZO) conductive film.
Wherein, described the first conductive electrode and the second conductive electrode include a plurality of base portions and perpendicular to the teat of base portion, adopt this structure effectively to increase the induction area of electrode, have improved touching the accuracy that detects.
On the basis of said structure, apparent, also need other parts such as signal processor etc. to realize complete capacitance touch function, this is well known to a person skilled in the art, repeats no more herein.
The wire of the first conductive electrode of internal-surface capacitive touch screen of the present utility model and the wire of the second conductive electrode along this internal-surface capacitive touch screen not homonymy draw, avoided the appearance of short circuit phenomenon, improved the reliability of using; By improving the planform of conductive electrode, improve the accuracy of touch sensitive simultaneously, taken full advantage of spatial area.
