It is understood that in the specific embodiment of the invention, " first " and " second " represents when relatively numerical relation
Unequal, it is comparatively speaking in mutual alignment relation, not refers in particular to.Such as: the first quantity is not equal to the second quantity；As claimed
One data line A is the first data wire, and another data line B is properly termed as the second data wire, and comparatively speaking, data wire B is also
Being properly termed as the first data wire, data wire A is properly termed as the second data wire；Additionally, the first data wire (or first grid line) is permissible

Spend identical) etc. the essentially identical data wire (or grid line) of function.
To achieve these goals, a kind of array base palte is embodiments provided, including flexible base board with in flexibility
The array layer formed on substrate, wherein, described array layer includes:
A plurality of grid line and a plurality of data lines, intersect and form multiple sub-pixel area on described flexible base board；
It is arranged at the thin film transistor (TFT) in described sub-pixel area, connects with corresponding data wire and grid line；
Wherein, described a plurality of data lines/grid line includes that the first signal transmssion line and length are more than secondary signal transmission line

The secondary signal transmission line of length more than secondary signal transmission line " show to be meant that in data wire/grid line and there is length
Different data wire/grid lines.
In array base palte described in the embodiment of the present invention, when there is the different signal transmssion line of length, long according to the two
The difference of degree, controls the area of section of the different signal transmssion line of length generated, longer signal transmission in manufacturing process
The area of section of line is relatively big, and therefore its impedance effect reduces accordingly, therefore, it is possible to make up the time delay brought owing to its length is longer,
Reduce the delay inequality between unlike signal transmission line, improve display performance.
In a particular embodiment of the present invention, form reason that different pieces of information line/length of grid line is different and differ, below first
Two kinds of situations are illustrated below.
In Fig. 2 a-2c, wherein signal transmssion line vertical distribution, and the most arranged in parallel, it is found that due to aobvious
Show that the shape of substrate is not that rectangle will result in the length of signal transmssion line different.
Fig. 3 is then another kind of situation.
As shown in Figure 3, it is found that flexible base board 6 therein is rectangular, but owing to signal transmssion line (includes in Fig. 3
Data wire 2 and grid line 3) relative to the angle of any one side of described flexible base board 6 be not equal to 90 degree (the most relative
Side arranged askew in flexible base board), thus while array base palte regular shape, but owing to signal transmssion line is relative to flexibility
Substrate arranged askew, now arises that the situation that the length of signal transmssion line is different.
It is understood that the embodiment of the present invention is a simplified thin film transistor (TFT) and data wire, the structural relation of grid line；
Ordinary circumstance: the grid of thin film transistor (TFT) is connected with grid line, the source electrode (or drain electrode) of thin film transistor (TFT) is connected with data wire, thin film
The drain electrode (or source electrode) of transistor is connected with pixel electrode (not shown)；Owing to drain electrode and the source electrode of thin film transistor (TFT) are making work
Skill is essentially identical, can exchange nominally.
It has been mentioned hereinbefore that the embodiment of the present invention key character is: described a plurality of data lines/grid line includes
One signal transmssion line and length are more than the secondary signal transmission line of the length of the first signal transmssion line, described secondary signal transmission line
Area of section more than the area of section of described first signal transmssion line.
Above-mentioned feature is divided into multiple situation, is respectively described below.
<situation one>
When the length difference of data wire/grid line, the display performance of system is determined by maximum transmitted time delay, when data wire/
When the area of section of grid line is identical, maximum delay is determined by data wire/grid line that data wire/grid line that length is maximum is minimum with length
Fixed.
Therefore, in a particular embodiment of the present invention, in situation one, it is only necessary to reduce the longest data wire/grid line time
Prolong and just can reduce the time delay between data wire/grid line.The most in a particular embodiment of the present invention, the longest data are increased
The area of section of line/grid line, then can reduce the time delay of the longest data wire/grid line, therefore reduce between data wire/grid line
Delay inequality.
This is described as follows.
Assuming that there is 2m data lines/grid line, its length is respectively as follows:
l；
l+Δ；
l+2Δ；
…
l+(2m-2)Δ、
l+(2m-1)Δ。
In the case of area of section is identical, the delay inequality that adjacent data wire/grid line is corresponding is respectively as follows:
T；
T；
……
T。
Between data wire/grid line that then prior art middle section area is identical, maximum delay difference is (2m-1) T.
And the method utilizing the embodiment of the present invention, then:
The delay inequality that adjacent data wire/grid line is corresponding is respectively as follows:
T；
T；
……
T-ΔT。
Then, between data wire/grid line, maximum delay difference is (2m-1) T-Δ T.
<situation two>
In situation one, it is assumed that there is 2m data lines/grid line, its length is respectively as follows:
l；
l+Δ；
l+2Δ；
…
l+(2m-2)Δ、
l+(2m-1)Δ。
In this case, in order to reduce time delay, the embodiment of the present invention by this 2m data lines/grid line according to length from little to
Big order is divided into n group (n for more than 2, less than the integer of 2m), and wherein data wire/grid line the length in first group is the shortest, and
Data wire in later group/grid line length is the longest, but the area of section of the data wire/grid line in each group is identical.
Meanwhile, the area of section of the data wire/grid line in first group is minimum, and the data wire/grid line in last group
Area of section is maximum.
Under this situation, from the form of expression, every a few data lines/grid lines, its area of section strengthens.
<situation three>
In two kinds of above-mentioned situations, all there is data wire/grid line that area of section is identical, but the most extreme in the case of, appoint
Data wire/grid line that two length of anticipating is different, the data that the area of section of data wire/grid line that length is longer is shorter more than length
The area of section of line/grid line.
In this case, it is assumed that the area of section of the first data lines/grid line is same as the prior art, then according to length from
Little to big order arrangement, the delay inequality between any two data lines/grid line all can reduce, then between data wire/grid line
Long time delay difference also can reduce.
This is described as follows.
Assuming that there is 2m data lines/grid line, its length is respectively as follows:
l；
l+Δ；
l+2Δ；
…
l+(2m-2)Δ、
l+(2m-1)Δ。
In the case of area of section is identical, the delay inequality that adjacent data wire/grid line is corresponding is respectively as follows:
T；
T；
……
T。
Then between data wire/grid line, maximum delay difference is (2m-1) T.
And the method utilizing the embodiment of the present invention, then:
The delay inequality that adjacent data wire/grid line is corresponding is respectively as follows:
T-ΔT1；
T-ΔT2；
……
T-ΔT2m-1。
Then, between data wire/grid line, maximum delay difference is (2m-1) T-(Δ T1+ΔT2+…+ΔT2m-1)。
In a particular embodiment of the present invention, in order to ensure the face, cross section of the first signal transmssion line and secondary signal transmission line
Long-pending difference, can be in the following way:
Section thickness is identical, and the cross-sectional width of secondary signal transmission line is more than the cross-sectional width of the first signal transmssion line；Or
Person
Cross-sectional width is identical, and the section thickness of secondary signal transmission line is more than the section thickness of the first signal transmssion line；Or
Person
Cross-sectional width and height all differ, and the product of the cross-sectional width of secondary signal transmission line and height is more than the first letter
The cross-sectional width of number transmission line and the product of height.
As a example by signal transmssion line is as data wire: in the orientation of data wire, the area of section of data wire can in etc.
