Description
Technical field
The utility model belongs to the display technique field, be specifically related to a kind of can be to the panel display board of bit correction.
Background technology
Panel display board itself is exactly one flat plate, does not have the electron-beam tube in the general display, does not have the projection distance problem during as large screen display, therefore, is a kind of more satisfactory display panel.Because its adopts matrixes control, so be called again matrix control flat pannel display or referred to as matrix display.The display material that it is controlled has: electroluminescent material, light emitting diode (LED), Organic Light Emitting Diode (OLED), plasma (PDP) and liquid crystal (LCD) etc.
In order to drive signal and driving power toward board transport such as panel display board such as LCD, PDP or OLED, need to paste a pair TCP, COF, the fexible film circuit boards such as FPCB (Flexible film).To utilize different direction conducting film (ACF) by FOG(Film on glass between display panel substrate and the fexible film circuit board) connection of binding structure.
Be illustrated in figure 1 as the upper general structure of paying fexible film circuit board c of pasting of display panel substrate a of panel display board.The upper FOG binding pin b that forms of display panel substrate a also forms the FOG binding pin b identical with display panel substrate binding pin specification on the fexible film circuit board c.Display panel substrate a and fexible film circuit board c bind together behind binding pin b exactitude position, realize fexible film circuit board counter plate board transport electric signal.
As shown in Figure 2, described display panel substrate a binding pin specification comprises interval Pitch and binding pin e self width width between the binding pin e.
Drive integrated circult (Driver IC) directly is bundled in the COG(Chip on Glass of panel display board a) situation of bindtype is that drive integrated circult is included in the panel display board a.In addition, fexible film can be arbitrary form of one of TCP/COF/FPCB etc.
During the FOG binding, the binding pin (PAD) on the display panel substrate and binding pin (PAD) position on the fexible film circuit board will be consistent mutually.If the inconsistent situation in binding pin (PAD) position on the binding pin (PAD) on the display panel substrate and the fexible film circuit board, open circuit (Open) or short circuit (Short) between the binding pin will occur, further causing can not be correctly to the bad problem of display panel substrate transmission of electric signals, and described electric signal comprises driving signal, driving voltage and drive current.
In addition, during the Practical manufacturing fexible film, because the manufacturing result of the reasons such as over etching (over etching) binding pin widths is thinner compared with design load, this can not carry out the contraposition problem with panel and fexible film in the time of will causing binding easilier accurately.
The utility model content
The purpose of this utility model is the problem of incidental contraposition dislocation during for the binding of the display panel substrate that solves existing panel display board and fexible film circuit board, proposed a kind of can be to the panel display board of bit correction.
The technical solution of the utility model is: can be to the panel display board of bit correction, comprise display panel substrate and fexible film circuit board, it is characterized in that, described display panel substrate comprises binding pin and contraposition pin, and described fexible film circuit board comprises binding pin and the contraposition pin that binding pin and the contraposition pin with described display panel substrate is complementary respectively.
Further, the contraposition pin of described display panel substrate and fexible film circuit board comprises the first contraposition pin, and described binding pin is interdependent between the first contraposition pin in twos.
Further, described the first contraposition pin is
Shape or
Shape or "+" shape or " non-" shape.
Further, the contraposition pin of described display panel substrate and fexible film circuit board comprises the second contraposition pin, described the second contraposition pin comprises a plurality of pins of the both sides of the binding pin between the first contraposition pin, mate mutually at described the second contraposition pin number and interval, and each pin widths of the second contraposition pin of one of described display panel substrate and fexible film circuit board is different.
The beneficial effects of the utility model: panel display board of the present utility model arranges potential electrode by display panel substrate and the fexible film circuit board at existing panel display board, second pair of potential electrode particularly is set, reduce the bit errors that display panel substrate and fexible film circuit board when binding produces, can improve the yields of production run.

Fig. 2 is the contraposition pin synoptic diagram of an embodiment of the present utility model;
Fig. 3 is the flexible PCB diagram of above-described embodiment actual fabrication of the present utility model;
Fig. 4 is the schematic diagram of another embodiment of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further elaborated.
As depicted in figs. 1 and 2, the a kind of of present embodiment can be to the panel display board of bit correction, comprise display panel substrate a and fexible film circuit board c, described display panel substrate a comprises binding pin e and contraposition pin, and described fexible film circuit board c comprises binding pin e and the contraposition pin that binding pin e and the contraposition pin with described display panel substrate a is complementary respectively.Described contraposition pin is used for being used for identification with the exactitude position of auxiliary binding pin at display panel substrate a and fexible film circuit board e binding.
Here, the contraposition pin of display panel substrate a and fexible film circuit board c comprises the first contraposition pin d, and described binding pin e is interdependent between the first contraposition pin d in twos.
Here, the first contraposition pin can for
Shape or
Shape or "+" shape or " non-" shape.
Be illustrated in figure 3 as the fexible film circuit board c of above-described embodiment Practical manufacturing.The formation that can find out the FOG binding pin b on the fexible film h is different from design standards pin f, and the Practical manufacturing result is compared with the narrow a little pin g of design standards pin f.This is owing to make on the fexible film circuit board or when gold-plated (Au, Sn, Ni etc.), because the error of operation, actual result is to produce the narrow pin g compared with design standards pin f.In general, the operation error of manufacturing fexible film circuit board is ± 0.01mm that different manufacturers may distinguish to some extent.Because the FOG binding pin on the binding pin of the FOG on the panel and the fexible film circuit board is difference to some extent, cause binding operation when carrying out, centering adjustment that can not be exquisite and the problem of contraposition.If correctly centering adjustment and contraposition, if the inconsistent situation in binding pin (PAD) position on the binding pin (PAD) on the panel and the fexible film circuit board, open circuit (Open) or short circuit (Short) between the binding pin will occur, further cause correctly to pass on electric signal (to drive signal, driving voltage, drive current) bad problem.
