Description
Technical field
The utility model relates to touch-screen, especially relates 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 adhere to specification; Touch-screen detect qualified after, touch-screen also will with the FPC(flexible PCB) hot pressing makes circuit external can control touch-screen.But owing to be subjected to space constraint, it is smaller that the electrode pin of some capacitive touch screen (PIN) width has to design, the capacitance plate design proposal of the individual layer multiple spot that has just occurred now 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) detection problem: the instrument of senses touch screen commonly used at present is to judge by resistance, short circuit and the open circuit situation of senses touch screen conductive channel whether the touch-screen quality is qualified, and the testing needle of this instrument general bigger (is 1.8mm tack pin as diameter).Therefore, the electrode pin that size is little can hinder and use conventional instrument to come the senses 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:, make capacitance touch screen with FPC hot pressing the time, need accurate contraposition, and high-precision contraposition meeting influences the hot pressing efficient of FPC because the width of electrode pin is narrow, the distance between the pin is little.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 coordinate that touch-screen is measured and the coordinate at each electrode group place detect this touch-screen as mode of comparing and exist unusually.
Summary of the invention
The purpose of this utility model is to detect and FPC hot pressing problem in order to solve the touch-screen that exists in the prior art, provides not only simple, and a kind of electrode pin of capacitive touch screen fast and easily.
The utility model is provided with substrate, is provided with transparent conductive patterns layer, alternating expression arrangement electrode pin, connecting line on 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 ellipse 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 utility model is arranged the touch screen electrode pin and is made into to arrange into alternating expression by traditional run-in index, to make full use 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 conventional instrument detecting and improves touch-screen and the efficient of FPC hot pressing.
For the senses 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, circle, ellipse etc.Equally, the electrode on the FPC also can be designed to other shape.The electrode pin area that described touch-screen is interspersed is made bigger, and the size of the last counter electrode of described FPC can be made littler, 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 be bigger by (1～3mm).Therefore, when arranging electrode pin and FPC hot pressing, described alternating expression can use more ACF glue (anisotropic conductive film).But, take all factors into consideration 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 utility model makes full use 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 detecting 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.
