Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is elaborated, but execution mode of the present utility model is not limited thereto.
Content as background technology part is known, and the live width how increasing FPC golden finger becomes the subject matter affecting conductivity.And as can be seen from Figure 3, the pinout of a lot of adjacent leads of the ITO of LCD is the same, principle of the present utility model is exactly the pin of the ITO of corresponding LCD is had identical pinout and adjacent multiple golden finger bodies make an agglomerate body, reaches the object increasing effectively crimping population.Below scheme of the present utility model is described in detail.
As shown in Figure 4, Figure 5, golden finger structure of the present utility model, comprise adhesive tape 101, golden finger body 102, golden finger body 102 is arranged on adhesive tape 101, adjacent multiple golden finger bodies 102 are made into an agglomerate body 103, and the pin of the ITO of the LCD corresponding to golden finger body 102 in agglomerate body 103 has identical pinout.
Wherein, golden finger body 102 is arranged on adhesive tape 101 and generally refers to that golden finger body 102 is fixedly connected with adhesive tape.
Wherein, the number of the golden finger body 102 in agglomerate body 103 is by having identical pinout and the number of the pin of the ITO of adjacent LCD is determined.As shown in Figure 4, adjacent two pins for the ITO of LCD have the situation of identical definition, and as shown in Figure 5, adjacent three pins for the ITO of LCD have the situation of identical definition.
Wherein, there is identical pinout refer to the function definition of pin and connect identical, such as, be all VCOM pin (referring to liquid crystal deflecting element common port voltage), or be all VGH pin (opening the voltage of TFT), or be all VGL pin (closing the voltage of TFT).
Agglomerate body 103 not only comprises the part of adjacent multiple golden finger bodies 102, also be included in the part between these golden finger bodies 102, as shown in Figure 4, agglomerate body 103 comprises B1, X1, B2 tri-part, this three part forms a unified entirety, as shown in Figure 5, agglomerate body 103 comprises B3, X2, B1, X1, B2 five part, and this five part forms a unified entirety.
