Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limitation of the invention.It also should be noted that in order to just
In description, only some but not all contents related to the present invention are shown in the drawings.
An embodiment of the present invention provides a kind of array substrates.
Fig. 1 is a kind of schematic top plan view of the structure of realization method of array substrate provided in an embodiment of the present invention.Fig. 2 is
