Abstract
In order to solve the problem of difficulty in inspecting COG binding pins and FOG binding pins of the existing flat display panel, the utility model provides a flat display panel structure for inspecting COG or COF binding defects. The flat display panel structure comprises a panel substrate, a driving IC and a flexible film circuit board, wherein the driving IC and a binding pin of the flexible film circuit board are connected with binding pins of the panel substrate respectively through a COG binding process and a COF binding process, the binding pins of the panel substrate comprise an ITO layer and a metal layer, the metal layer of the binding pin of the panel substrate is in a window shape, and window edges of the window-shaped binding pin are used for forming binding pins so as to realize the electrical connection with the driving IC and the flexible film circuit board. By adopting the flat display panel structure, the states of the binding pins of the panel substrate of the flat display panel bound with the driving IC and the flexible film circuit board can be conveniently inspected; and the binding state inspection process can be simplified through the scheme in the production process, thereby improving the production efficiency.
Description
Technical field
The utility model belongs to the Display Technique field, is specifically related to a kind of panel display board structure that is used to check COG or COF binding defective.
Background technology
Panel display board (FPD, Flat panel Display) itself is exactly an one flat plate, does not have the electron-beam tube in the general display, does not have the projection distance problem during as large scale display, therefore, is a kind of more satisfactory display floater.Because its matrix that adopt is controlled more, shows so be called matrix control flat panel display again or abbreviate matrix as.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.
For toward panel display board such as board transport drive signal and driving powers such as LCD, PDP or OLED, need to paste a pair TCP, COF, fexible film circuit boards such as FPCB (Flexible film) and drive IC.Be to utilize different direction conducting film (ACF, Anisotropic Conductive Film) between display panel substrate and fexible film circuit board and the drive IC by FOG(Film on glass) and COG (Chip on Glass) binding operation bind together.In actual fabrication; the problem of panel performance even function because binding is bad might appear; the effect of binding is checked described inspection is normally judged by the state of observing ACF conducting particles (Conductive Particle) so can finish the back in the binding operation usually.
Be illustrated in figure 1 as existing panel display board (LCD, PDP, OLED) and go up the general structure of binding drive IC and fexible film circuit board (Flexible film).Fig. 2 is the sectional view and binding defect inspection direction (Inspection direction) schematic diagram of described COG of Fig. 1 and FOG binding part.As shown in Figure 2, on panel, utilize ITO and metal level (Metal layer) and form COG binding pin a and FOG binding pin c, utilize the binding pin b of ACF (Anisotropic Conductive Film) binding drive IC and the binding pin d of fexible film circuit board then.
When to the binding state inspection of binding pin being to us, usually need observe the state of its conducting particles according to direction as shown (Inspection direction), but because the influence of the said structure of panel binding pin (COG binding pin a and FOG binding pin c), particularly the shape of metal level design can cause checking that according to direction as shown (Inspection direction) binding state of binding pin is that sight line is blocked by metal level, and then influence is to the inspection of binding pin state.
The utility model content
The purpose of this utility model is the deficiency for COG binding pin that solves existing panel display board and FOG binding pin inspection difficulty, has proposed to be used to check the panel display board structure of COG or COF binding defective.
The technical solution of the utility model is: the panel display board structure that is used to check COG or COF binding defective, comprise display panel substrate, drive IC and fexible film circuit board, the binding pin of described drive IC and fexible film circuit board is connected with the binding pin of display panel substrate with COF binding operation by COG respectively, described display panel substrate binding pin comprises ITO layer and metal level, it is characterized in that, the metal level of described display panel substrate binding pin is a window-shaped, the window limit of the binding pin of described window-shaped is used to form binding pin realization and drive IC and fexible film circuit board and is electrically connected, and the window of the binding pin of described window-shaped is as the form of checking binding pin binding state.
The window limit of above-mentioned window-shaped binding pin is continuous annular window limit or continuous quadrangle annular window limit or the discontinuous window limit with breach.
The beneficial effects of the utility model: the panel display board structure that is used to check COG or COF binding defective of the present utility model, comprise window-shaped binding pin, utilize the window of window-shaped binding pin, the state of the binding pin that the display panel substrate that can check panel display board easily and drive IC and fexible film circuit board are bound; Can simplify the binding state audit program by this scheme in process of production, enhance productivity.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further elaborated.
As shown in Figure 3, the panel display board structure that is used to check COG or COF binding defective of present embodiment, comprise display panel substrate, drive IC and fexible film circuit board, the binding pin of described drive IC and fexible film circuit board is connected with the binding pin of display panel substrate with COF binding operation by COG respectively, described display panel substrate binding pin comprises ITO layer and metal level, the metal level of described display panel substrate binding pin is a window-shaped, the window limit e of the binding pin of described window-shaped is used to form binding pin realization and drive IC and fexible film circuit board and is electrically connected, and the window f of the binding pin of described window-shaped is as the form of checking binding pin binding state.
Here, the window limit e of window-shaped binding pin is continuous annular window limit or continuous quadrangle annular window limit or the discontinuous window limit with breach.
As can be seen, the panel display board structure that is used to check COG or COF binding defective of the present utility model, comprise window-shaped binding pin, utilize the window of window-shaped binding pin, the state of the binding pin that the display panel substrate that can check panel display board easily and drive IC and fexible film circuit board are bound; Can simplify the binding state audit program by this scheme in process of production, enhance productivity.
