Summary of the invention
At above-mentioned technical matters, by patch area is arranged at fanout area, and, can make fanout area obtain extending with the fanout area separated into two parts, be very helpful for reducing lead resistance difference.
One of purpose of the present invention is to provide a kind of active-device array basal plate, the periphery circuit region that it has the viewing area and is positioned at this periphery, viewing area.Periphery circuit region comprises driving circuit and fanout area.Fanout area comprises the many leads that extend to this driving circuit from this viewing area.Periphery circuit region also comprises the patch cord with preparing structure, and this preparing structure is positioned at this fanout area, and this fanout area is divided into first and second portion.
The present invention also provides a kind of display panel, comprises above-mentioned active-device array basal plate, second substrate and liquid crystal layer.Second substrate is disposed at this active-device array basal plate top.Liquid crystal layer is disposed between this active-device array basal plate and this second substrate.
By the present invention, can dwindle the resistance difference between each lead of fanout area, improve the display quality of display panel.

Embodiment
For making purpose of the present invention, structure, feature and function thereof there are further understanding, cooperate embodiment to be described in detail as follows now.
Display panel generally comprises active-device array basal plate, second substrate and liquid crystal layer.Second substrate is disposed at this active-device array basal plate top.Liquid crystal layer is disposed between this active-device array basal plate and this second substrate.
See also Fig. 1, Fig. 1 is the structural representation of active-device array basal plate 1.The periphery circuit region 20 that active-device array basal plate 1 has viewing area 10 and is positioned at these 10 peripheries, viewing area.Periphery circuit region 20 comprises scan drive circuit 201, data drive circuit 202 and fanout area 203 and 204, fanout area 203 comprise many from the viewing area 10 leads that extend to scan drive circuit 201, fanout area 204 comprise many from the viewing area 10 leads that extend to data drive circuit 202.Be arranged in the chip for driving of scan drive circuit 201 and data drive circuit 202, provide sweep trace and the data line of signal to the viewing area 10 via separately fanout area 203 and 204 respectively.In actual applications, the quantity of fanout area does not limit.
Please in conjunction with Fig. 2, Fig. 2 is near the partial enlarged drawing of fanout area 204 circuit in the prior art.Patch area 206 is arranged between fanout area 204 and the static electricity prevention and curing portion 208.In actual applications, static electricity prevention and curing portion 208 can be short-circuited conducting sleeve (short ring).Adjusting at patch area 206 can't be influential to mending course, but can increase helpful to fanout area 204 spaces.
Principle of the present invention is, with the fanout area separated into two parts, first extends to patch area by signal conductor by chip for driving pressing terminal, and second portion extends to the viewing area by signal conductor by patch area.For the warp architecture that reduces lead resistance difference moves to second portion, then fanout area can be done bigger extension, also be very helpful for the reduction of lead resistance difference.
See also Fig. 3, Fig. 3 is near the partial enlarged drawing of fanout area 304 circuit of one embodiment of the invention.Please in conjunction with Fig. 1, fanout area 304 is suitable with fanout area 204 positions, and periphery circuit region 20 comprises the patch cord with preparing structure 306, and preparing structure 306 is positioned at fanout area 304, and fanout area 304 is divided into first 3041 and second portion 3042.In one embodiment, first 3041 is contiguous with viewing area 10.Second portion 3042 is positioned at the side of relative this preparing structure 306 away from this viewing area 10.Many leads of second portion 3042 have warp architecture 3043, and it can have different degree of crook as required, in order to reduce the resistance difference between those leads.In actual applications, warp architecture 3043 can be " bow " shape winding structure.
See also Fig. 4, Fig. 4 is near the partial enlarged drawing of fanout area 404 circuit of another embodiment of the present invention.Please in conjunction with Fig. 1, fanout area 404 is suitable with fanout area 204 positions, and periphery circuit region 20 also comprises static electricity prevention and curing portion 408 except that comprising preparing structure 406, and static electricity prevention and curing portion 408 is positioned at fanout area 404.In one embodiment, static electricity prevention and curing portion 408 is positioned at the second portion 4042 of fanout area 404.Need to prove that static electricity prevention and curing portion 408 also can be positioned at the first 4041 of fanout area 404.In actual applications, static electricity prevention and curing portion 408 can be the short circuit figure that is provided with at the periphery circuit region 20 of active-device array basal plate 1 in order to prevent static.
