Abstract
The utility model discloses a five-line resistor type touch screen which has a two layer structure including an upper line and a lower line. Each of the upper and lower lines comprises a line substrate, a conducting layer, elargol routing and an insulating layer, and the lower line is also provided with an insulation point layer and a cloud atlas, wherein the cloud atlas and the elargol routing of the lower line are on a same plane, the upper and lower lines are fixed through a double faced adhesive tape layer, the elargol routing of the lower line is laid out on the upper line through a through hole jumper means, and the elargol routing of the upper and lower lines is connected to a connector through an entire flexible circuit board. Wiring on double layers are led out through a jumper means, which overcomes the limits caused by routing totally on the lower line, minimizes screen body space for routing, and provides more design space for the cloud atlas. The linear effect and the resolution of a screen body are improved.
Description
Technical field
The present invention relates to a kind of touch screen structure, relate in particular to a kind of film to five wire resistive touch screens of glass structure.
Background technology
Present five wire resistive touch screens are mainly used in big-and-middle size and show, traditional five wire resistive touch screens are by ITO laminated polyester film and the two-layer double-layer structure that combines of ito glass layer, two-layer between by transparent insulation point interval.ITO laminated polyester film and the ito glass layer of five wire resistive touch screens respectively are coated with transparency conducting layer, the conductive layer of its ITO laminated polyester film is as detecting layer, the conductive layer of ito glass layer is added in the voltage field of both direction on the conduction workplace of glass, when touch signal is arranged, detect the magnitude of voltage of contact point X-axis and Y-axis with regard to timesharing, thereby record the position of touch point.
The conductive layer of five wire resistive touch screens is drawn by the elargol cabling and is connected on controller or the mainboard, generally is that detecting layer is provided with an elargol cabling, and the conductive layer of ito glass layer is provided with four elargol cablings.Therefore in order to satisfy linear requirement, five wire resistive touch screens need to have enough wide touch-screen frame (distance between visible area and the screen body profile) could satisfy job requirement.But along with consumer demand changes, present big-and-middle size screen proposes harsh requirement in order to press close to fashion and requirement attractive in appearance to the touch-screen frame.The design of narrow limit occurred in this case, namely sacrificed or reduce certain parameter and deacclimatize the restriction that the frame size is brought.Therefore, the restriction that brings in order to adapt to the frame size need in the situation that how narrow limit accomplishes to sacrifice or to reduce the functional parameter of screen body, solves cabling difficulty, linear value difference (especially corner), problem that resolution is low.
Summary of the invention
For above deficiency, the invention provides and a kind ofly can reduce frame distance but can accomplish five wire resistive touch screens that cabling space is large, the linearity is effective, resolution is high.
The present invention realizes by following scheme:
A kind of five wire resistive touch screens, comprise circuit and lower circuit double-layer structure, upper and lower circuit respectively comprises circuit base material, conductive layer, elargol cabling, insulation course, lower circuit also is provided with insulating point layer, cloud atlas, the elargol cabling of cloud atlas and lower circuit at grade, upper and lower link tester is crossed layers of two-sided and is fixed, and the elargol cabling of lower circuit passes through the mode layout of perforation wire jumper to upper circuit, and the elargol cabling of upper and lower circuit is connected on the connector by the flexible PCB of full wafer.
Can also do by the following technical programs further perfect:
Further, described lower circuit is provided with two elargol cablings, and upper circuit is provided with three elargol cablings, and the elargol cabling of lower circuit passes through the mode layout of perforation wire jumper to upper circuit.
The present invention draws in the wiring of two sandwich circuits by the mode of wire jumper by the cabling of drawing that will shield four jiaos of bodies, the limitation that original cabling all is arranged in lower circuit is broken, reduce the screen body space of cabling, provide more design space for cloud atlas simultaneously, it is large that the cloud atlas space becomes, and the linearity effect that the screen physical efficiency realizes can be better; The live width of elargol lead-in wire is also widened, and utilizes live width that the impact of elargol loop resistance is changed elargol and walks line resistance, and then utilize line resistance with the relation of screen body resolution, reduces within the specific limits the cabling resistance value, improves the resolution of screen body; Also because the elargol cabling has been widened, reduce the requirement to processing technology, effectively improved yields.
