[0005] However, since the thickness of the metal in the terminal area is only 3000-7000 angstroms, and the width does not exceed 10 μm, it is difficult for ACF (anisotropic conductive film) glue to bind such a small-area terminal area cross-sectional structure to the COF gold finger uniformly and electrically. together

Abstract
The invention provides an ultra-narrow frame terminal area structure, a manufacturing method and a display panel. The ultra-narrow frame terminal area structure comprises a metal layer arranged on a substrate, an insulating layer arranged on the metal layer and the naked substrate, an insulating protection layer arranged on the insulating layer and an organic insulating layer arranged on the insulating protection layer, wherein a groove structure which runs through the insulating layer, the insulating protection layer and the organic insulating layer is disposed corresponding to a metal wire running area of the metal layer, and the groove structure is filled with conductive material. According to the ultra-narrow frame terminal area structure, the manufacturing method and the display panel, the sectional area of the ultra-narrow frame terminal area structure can be enlarged, binding resistance of the ultra-narrow frame terminal area structure and a COF (chip on film) is reduced, and display quality of the display panel is improved.
Description
technical field [0001] The invention belongs to the technical field of display panel production, and in particular relates to an ultra-narrow frame terminal area structure and a production method, and a display panel. Background technique [0002] With the development of display technology, ultra-narrow bezel and splicing screen technology have been applied maturely. The current ultra-narrow bezel LCD display frame has reached 5mm, and some frames have even reached 3mm. Such a frame width has fully met the aesthetic requirements for ordinary mobile phones, tablets, computers and TVs. [0003] Ordinary flat panel display panel structure such as figure 1 As shown, it includes a display area 11 and a frame area 12. The display area 11 is an area for displaying a picture, and the frame area 12 includes a peripheral wiring area and a dummy area (blank area). The peripheral routing area also includes OLB121 (outer lead connection area), which mainly refers to the area where the ...
