Abstract
The invention provides an electrode pin of a capacitive touch screen, which relates to touch screens, is not only simple and practicable but also quick and convenient. The capacitive touch screen comprises a substrate, wherein a transparent electric conduction pattern layer, and staggered arraying electrode pins and connecting wires are arranged on the substrate; and the staggered arraying electrode pins are externally connected with a control circuit, and the transparent electric conduction pattern layer is connected with the staggered arraying electrode pins through the connecting wires. The electrode pins fully utilize electrode pin spaces, the conventional electrode pin parallel distribution is changed, the staggered arraying electrode pins which satisfy instrument detection and facilitate flexible printed circuit (FPC) hot pressing are designed, so that the purposes of quickly detecting the touch screen through using an instrument and improving the hot pressing of the touch screen and an FPC, and the product production efficiency is increased; and the method is not only simple but also time-saving and cost-saving.
Description
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 the various digital information systems, from small sized product such as mobile phone, digital product,, arrive medium-sized product such as automatic navigator, panel computer, game machine, household electrical appliance, can see the touch-screen product again on large product such as common query system, portable computer, Medical Instruments, 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 the FPC(flexible PCB) hot pressing be so that outside circuit can be controlled touch-screen.But owing to being subject to space constraint, it is smaller that the electrode pin of some capacitive touch screen (PIN) width has to design, the present capacitance plate design proposal of firm incipient individual layer multiple spot particularly, the width of electrode pin is very little, generally about 0.15～0.2mm.
The narrow electrode pin of width can produce following problem:
(1) test problems: at present the instrument that detects touch-screen commonly used is to judge by the resistance, short circuit and the open circuit situation that detect the touch-screen conductive channel whether the touch-screen quality is qualified, and the testing needle of this instrument generally larger (be 1.8mm tack pin such as diameter).Therefore, the electrode pin that size is little can hinder with conventional instrument and detect touch-screen.And the efficient that detects manually is low, and it has seriously restricted the production efficiency of capacitive touch screen.The detection robotization that touches product replaces manual detection to seem very urgent.
(2) FPC hot pressing problem: because the width of electrode pin is narrow, the distance between the pin is little, so that capacitance touch screen needs exactitude position with FPC hot pressing the time, and high-precision contraposition meeting affects the hot pressing efficient of FPC.Simultaneously, the displacement that produces 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 the circuit board to be connected to the form of a certain particular level, and whether the mode that the coordinate that touch-screen is measured and the coordinate at each electrode group place compare detects this touch-screen and exist unusually.
Summary of the invention
The objective of the invention is to detect and FPC hot pressing problem in order to solve the touch-screen that exists in the prior art, provide a kind of not only simple, and the electrode pin of capacitive touch screen fast and easily.
The present invention is provided with substrate, is provided with transparent conductive patterns layer, alternating expression arrangement electrode pin, connecting line at substrate; Described alternating expression is arranged the electrode pin external control circuit, and the transparent conductive patterns layer is arranged between the electrode pin with alternating expression and is connected by connecting line.
The width that described alternating expression is arranged electrode pin can be 1～3mm.
The shape that described alternating expression is arranged electrode pin can be rectangle, square, circle or oval etc.
Described alternating expression is arranged electrode pin and can be adopted vertical setting of types row, horizontally-arranged row or tiltedly arrange, and described connecting line can be at homonymy or homonymy not.
The present invention is arranged the touch screen electrode pin and makes into to arrange into alternating expression by traditional run-in index, to take full advantage of the pin space; The size that described alternating expression is arranged electrode pin requires to make according to detecting instrument and FPC hot pressing; Electrode on the testing needle of described detecting instrument and the described FPC also respective production becomes alternating expression to arrange, and forms corresponding one by one with the electrode pin of described touch-screen alternating expression.Thereby described alternating expression is arranged electrode pin and is applicable to the efficient that conventional instrument detected and improved touch-screen and FPC hot pressing.
For the detection touch-screen that instrument is more convenient for, the above-mentioned electrode pin that relates to also can be designed to other shape, as square, circular, oval etc.Equally, the electrode on the 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 the upper counter electrode of described FPC can be made less, can allow to provide, relatively large hot pressing bit errors or displacement, thereby reduce FPC hot pressing contraposition difficulty, enhance productivity.
With respect to the electrode pin that present touch-screen run-in index is arranged, described alternating expression is arranged the electrode pin space can larger (1～3mm).Therefore, when arranging electrode pin and FPC hot pressing, described alternating expression can use more ACF glue (anisotropic conductive film).But, considering ACF glue consumption, touch-screen detection efficiency and FPC hot pressing efficient, the touch screen electrode pin design that described alternating expression is arranged will significantly be enhanced productivity, be saved production cost.
Electrode pin of the present invention takes full advantage of the pin space of electrode, change the run-in index arranged distribution of traditional electrode pin, design and meet the electrode pin that uses instrument to detect and be convenient to the alternating expression arranged distribution of FPC hot pressing, reached and used instrument fast detecting touch-screen and improve the purpose of touch-screen and FPC hot pressing, improved production efficient.Method not only method is simple, and saves time and expense.
