Abstract
The utility model discloses a capacitive touch screen. The capacitive touch screen comprises a substrate layer, a transparent conductive layer, a flexible circuit board and a protective layer, wherein the transparent conductive layer is arranged on the substrate layer, the protective layer is arranged on the transparent conductive layer, and outgoing lines of the transparent conductive layer are arranged at the same end of a touch screen body, and are connected with the flexible circuit board correspondingly arranged at one end of the touch screen body. The capacitive touch screen can realize a narrow-frame display screen or a display screen without a frame, improves the science and technology sense of the appearance of the obverse side of a product, reduces the width of the product to obtain a good grip feeling, can be more attractive and more elegant, saves materials, reduces cost, is simple in technology, and meets the requirements of modern people.
Description
Technical field
The utility model relates to the touch-screen field, relates in particular to a kind of capacitive touch screen.
Background technology
Touch-screen is widely used in as equipment such as mobile phone, media player, navigational system, digital camera, game stations as a kind of man-machine interaction mode easily.
Have by the touch technology classification: infrared touch technology, electric resistance touch-control technology, sound wave touch technology and capacitive touch control techniques.At present, most widely used in mobile phone and panel computer is the capacitive touch control techniques.
The structure that adopts the capacitive touch screen of capacitive touch control techniques is mainly to plate indium oxide layer tin (ITO) as transparent conductive film on glass screen, then adds the lastblock cover glass at conductor layer, and conductor layer and inductor can be thoroughly protected in two glass designs.Capacitance type touch control screen all plates long and narrow electrode on touch screen four limits, when forming a low-voltage AC electric field user Touch Screen in electric conductor, due to people's bulk electric field, can form a coupling capacitance between finger and conductor layer, the electric current that four limit electrodes send can flow to the contact, and the strong and weak distance with pointing electrode of electric current is directly proportional, and is positioned at ratio and power that controller after Touch Screen just can calculate electric current, accurately calculates the position of touch point.Two glass of capacitive touch screen not only can be protected conductor and inductor, prevent that more effectively the external environment factor from impacting touch screen, even if screen speckles with filthy dust or oil stain, capacitance type touch control screen still can accurately be calculated touch location.
According to the structure of conventional touch screen, cabling mode comprises from the extension line at the two ends, left and right of touch-screen, or the extension line at two ends, up and down, be connected with the flexible circuit board that is positioned at the touch-screen upper end again, and for attractive in appearance, these cablings zones covers with printing ink usually, i.e. usually said touch-screen frame.Extension line is by pitch-dark the stopping on cover plate, the pitch-dark frame that consists of the mobile phone display screen curtain, but the existence of frame causes the indication range of mobile phone or other digital product screens to be dwindled.Yet along with the consumer is more and more higher to the requirement of smart mobile phone outward appearance and experience, it is more and more narrow that the touch-screen frame wishes to do, or even Rimless, so that product has more powerful expressive force, and reduces costs.
