Specific embodiment
The explanation of following embodiment is referred to the additional illustration, the specific reality that can be used to implement to illustrate this announcement
Apply example.The similar unit of structure is with being given the same reference numerals in the figure.
The realization process of detailed this announcement embodiment with reference to the accompanying drawing.
In general production process, in order to realize the narrow frame of display panel, present GOA type panel is in array substrate
The position of corresponding frame glue is provided with metallic circuit line, gate driving function is realized, for example, it may be grid line.In order to save into
This, grid line will not generally use transparent conductor wire, but use the metals such as aluminium, titanium, nickel or its alloy, not have saturating
Photosensitiveness.Therefore, when carrying out the irradiation of UV light, metallic circuit line meeting shield portions UV light, frame glue can not be irradiated by UV light completely
It arrives, leads to frame glue solidification not exclusively, the bonding between array substrate and color membrane substrates is insecure.
Fig. 1 to Fig. 1 is please referred to, Fig. 1 is the patch of array substrate and color membrane substrates during this announcement frame-sealing glue coating method
