Description

The electrode pin of capacitive touch screen
Technical field
The present invention relates to touch-screen, especially relate to a kind of electrode pin of capacitive touch screen.
Background technology
Capacitive touch screen is as a kind of novel human-computer interaction interface, be widely used on various digital information system, from small sized product as mobile phone, digital product, to medium-sized product as automatic navigator, panel computer, game machine, household electrical appliance, again to large product as common query system, portable computer, Medical Instruments can see touch-screen product, market outlook are very considerable.After touch-screen is produced, need to detect its function and whether meet designing requirement; Touch-screen detect qualified after, touch-screen also will with FPC(flexible PCB) hot pressing makes outside circuit to control touch-screen.But owing to being subject to space constraint, it is smaller that electrode pin (PIN) width of some capacitive touch screen has to design, the particularly capacitance plate design proposal of present firm incipient individual layer multiple spot, the width of electrode pin is very little, generally at about 0.15 ~ 0.2mm.
The narrow electrode pin of width can produce following problem:
(1) test problems: at present the conventional instrument detecting touch-screen is resistance by detecting touch-screen conductive channel, short circuit and open circuit situation judge that whether touch-screen quality is qualified, and the testing needle of this instrument general larger (if diameter is 1.8mm tack pin).Therefore, the electrode pin that size is little can hinder and use conventional instrument to detect touch-screen.And the efficiency detected manually is low, it seriously constrains the production efficiency of capacitive touch screen.The detection robotization touching product replaces manual detection to seem very urgent.
(2) FPC hot pressing problem: the distance because the width of electrode pin is narrow, between pin is little, make capacitance touch screen needing exactitude position with during FPC hot pressing, and high-precision contraposition can affect the hot pressing efficiency of FPC.Meanwhile, the displacement produced when less bit errors or FPC hot pressing all can cause product rejection.
Chinese patent CN101819496A discloses a kind of detection method of capacitive touch screen, it utilizes a series of electrode groups on circuit board to be connected to the form of a certain particular level, and the mode that the coordinate at the coordinate measured by touch-screen and each electrode group place compares detects whether this touch-screen exists exception.
Summary of the invention
The object of the invention is to detect and FPC hot pressing problem to solve the touch-screen that exists in prior art, providing one not only simple, and the electrode pin of capacitive touch screen fast and easily.
The present invention is provided with substrate, and substrate is provided with transparent conductive layer, alternating expression arrangement electrode pin, connecting line; Described alternating expression arrangement electrode pin external control circuit, transparent conductive layer and alternating expression arrange between electrode pin and are connected by connecting line.
The width of described alternating expression arrangement electrode pin can be 1 ~ 3mm.
The shape of described alternating expression arrangement electrode pin can be rectangle, square, circle or oval etc.
Described alternating expression arrangement electrode pin can adopt that vertical setting of types arranges, horizontally-arranged row or tiltedly arrange, and described connecting line can at homonymy or not homonymy.
Touch screen electrode pin is arranged by traditional run-in index and is changed to alternating expression arrangement, to make full use of pin space by the present invention; The size of described alternating expression arrangement electrode pin requires to make according to detecting instrument and FPC hot pressing; The testing needle of described detecting instrument becomes alternating expression to arrange with the electrode on described FPC also respective production, and forms one_to_one corresponding with the electrode pin of described touch-screen alternating expression.Thus described alternating expression arrangement electrode pin is applicable to conventional instrument and detects and the efficiency improving touch-screen and FPC hot pressing.
In order to the detection touch-screen that instrument is more convenient for, the above-mentioned electrode pin related to also can be designed to other shape, as square, circular, oval etc.Equally, the electrode on FPC also can be designed to other shape.The electrode pin area comparison that described touch-screen is interspersed more greatly, and the size of counter electrode can make less on described FPC, can allow to provide, relatively large hot pressing bit errors or displacement, thus reduce FPC hot pressing contraposition difficulty, enhance productivity.
Relative to the electrode pin of current touch-screen run-in index arrangement, described alternating expression arrangement electrode pin space can larger (1 ~ 3mm).Therefore, more ACF glue (anisotropic conductive film) can be used when described alternating expression arrangement electrode pin and FPC hot pressing.But consider ACF glue consumption, touch-screen detection efficiency and FPC hot pressing efficiency, the touch screen electrode pin design of described alternating expression arrangement significantly will be enhanced productivity, be saved production cost.
Electrode pin of the present invention makes full use of the pin space of electrode, change the run-in index arranged distribution of traditional electrode pin, design the electrode pin meeting the alternating expression arranged distribution using instrument to detect and to be convenient to FPC hot pressing, reach and use instrument to detect touch-screen fast and improve the object of touch-screen and FPC hot pressing, improve production efficiency.Method not only method is simple, and saves time and expense.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
See Fig. 1, the embodiment of the present invention is provided with substrate, and substrate is provided with transparent conductive layer 100, alternating expression arrangement electrode pin 101 and connecting line 102; Described alternating expression arrangement electrode pin 101 external control circuit, transparent conductive layer 100 and alternating expression arrange between electrode pin 101 and are connected by connecting line 102.
The width of described alternating expression arrangement electrode pin 101 is 1 ~ 3mm.
The shape of described alternating expression arrangement electrode pin 101 is rectangle.
Described alternating expression arrangement electrode pin 101 can adopt that vertical setting of types arranges, horizontally-arranged row or tiltedly arrange, and described connecting line 102 can at homonymy or not homonymy.The live width of described connecting line 102 can be prepared less of to vacate greater room to design alternating expression arrangement electrode pin 101; The size of alternating expression arrangement electrode pin 101 requires to make according to detecting instrument and flexible PCB FPC hot pressing; The size of the corresponding probe of detecting instrument or the counter electrode 103 of flexible PCB can design less of a little to increase the hot pressing FPC bit errors and detection that allow.
Touch screen electrode pin is arranged by traditional run-in index and is changed to alternating expression arrangement, to make full use of pin space by the present invention; The size of described alternating expression arrangement electrode pin requires to make according to detecting instrument and FPC hot pressing; The testing needle of described detecting instrument becomes alternating expression to arrange with the electrode on described FPC also respective production, and forms one_to_one corresponding with the electrode pin of described touch-screen alternating expression.Thus described alternating expression arrangement electrode pin is applicable to conventional instrument and detects and the efficiency improving touch-screen and FPC hot pressing.
