In 10, it is provided with a plurality of conducting wire 200, the length (size i.e. on its extending direction) of each conducting wire 200 is passed from centre to two sides
Increase, the resistance difference between the conducting wire of different length is very big, and in display, the resistance difference on each conducting wire is bigger, generates
Resistance/capacitance delay (i.e. Resistance Capacitance delay, referred to as RC delay) be more obvious, lead to signal
Transmission delay is more serious, shows that the effect of picture is poorer.
Especially for the display base plate using High Pin Count (high number of pins) design, due on the display base plate
It is provided only with IC and fanout area of a driving, when the pin number of driving IC is very more, corresponding conducting wire in fanout area
Quantity is consequently increased, and the degree positioned at the conducting wire outward bending of central conductor two sides is also bigger, so that in limited fanout area
A fairly large number of conducting wire can be accommodated down, bigger so as to cause the difference in length between each conducting wire, resistance difference also increases therewith
Add, causes display effect worse.
To solve the above problems, the relevant technologies are proposed using the lesser metal of resistivity as fanout area conducting wire, and right
Conducting wire carries out the design of " bow " font, as shown in Figure 2 or Figure 3, by using the conducting wire 200 of " bow " shape pattern, increases former
The conductor length of the lesser intermediate region of this length, to reduce the difference in length between each conducting wire, to reduce due to two sides
Viewing area two sides differ greatly bad with centre display picture color caused by conducting wire is long, central conductor is short.
However, the wire pattern due to " bow " font is complicated, there is more bending part, and between adjacent two conducting wires
Spacing it is very small, increasing fanout area wiring difficulty so that being easy to happen overlap joint between two adjacent conducting wires leads to object-line
Poor short circuit (Short) occurs for road, is unfavorable for the high number of pins and narrow frame design of display base plate.
Based on this, to reduce the resistance difference between longer fan out-conductor and shorter central conductor, while fan is reduced
Area is routed difficulty out, so that display base plate is more suitable for the requirement of high number of pins and narrow frame design, one side of the embodiment of the present invention
