Structure, such as the first fan-out structure 41, the second fan-out structure 42 and third fan-out structure 43, these fan-out structures 41,42 and 43 rows
Cheng Yilie or depend on it is one arranged in a straight line, and each other not arrange equidistantly, wherein each fan-out structure 41,42 and 43 is fanned out to
Conducting wire is the line widths such as non-.In Fig. 4 in the existing fan-out structure of the part (B) display, each fan-out structure is equidistant arrangement, and
The fan out-conductor of each fan-out structure such as is at line widths and the equidistantly arrangement.In third embodiment of the invention, when fan-out structure or drive
Dynamic circuit is to be put using non-equidistant and when position has determined, can be confirmed according to the placement position of rainbow figure and driving circuit and be fanned
Go out to originate the position of conducting wire, further according to the position software for being fanned out to terminal conducting wire (fanout end) while pulling out all be fanned out to
Conducting wire, fan out-conductor at this time is the line widths such as non-.By this mode, developer can be more flexiblely on circuit layout
Put the position of fan-out structure or driving circuit.
The present invention increases the height extension area of fan-out structure side by the height of the height extension area of control fan-out structure
Height, reduce the height of the height extension area of the other side, the wiring space needed for the fan out-conductor of the other side can be met,
Promote the elasticity of configuration.In addition, this asymmetrical fan out-conductor configuration can pass through the mobile position for being fanned out to starting conducting wire
To realize, and the frame of driving circuit or driving chip can be reduced by controlling the height of the height extension area of fan-out structure
(border).In addition, working as source electrode to WOA (the wire on array) fan out-conductors of grid (Source to Gate) or walking line number
It measures more, and when being required to WOA cabling resistance values, this asymmetrical fan out-conductor configuration can also be used, because it can be solved
Certainly panel narrow frame is configured using this asymmetrical fan out-conductor because WOA resistance values are unsatisfactory for cannot achieve due to requirement the problem of
The border width that panel can effectively be reduced, further meets the needs of narrow frame.In addition, the fan-out structure of the present invention can be real
Existing each fan-out structure is not put equidistantly, and the elasticity on circuit layout is promoted.
In conclusion although the present invention is disclosed above with preferred embodiment, above preferred embodiment is not to limit
The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention
Decorations, therefore protection scope of the present invention is subject to the range that claim defines.
