But, the duration of charging of first active member 251 and second active member 252 can influence the display quality of dot structure 208A.So the signal transmission quality of all sweep traces 211 is can not difference too big in the active component array base board 200.Opposite, the duration of charging of gauge tap 271 can directly not influence the display quality of dot structure 208A, so the signal transmission quality tolerable of control line 212 has bigger difference.Therefore, below propose several configuration modes and change the impedance of each lead to adjust the transmission quality of each lead accordingly.
Fig. 4 is the synoptic diagram of the fanout area 206 of Fig. 2, and the local enlarged diagram of fanout area 206.Please refer to Fig. 2 and Fig. 4, many main transmission lines 231 are arranged in the surrounding zone 204 of substrate 201, and many main transmission lines 231 are connected in multi-strip scanning line 211.Many transmission lines 232 are arranged in the surrounding zone 204 of substrate 201, are connected in many control lines 212, and many transmission lines 232 are arranged among many main transmission lines 231 with being mingled with.In addition, active component array base board 200 also comprises a plurality of signal bonding pad 236, is arranged in the surrounding zone 204 of substrate 201.Many main transmission lines 231 are connected between multi-strip scanning line 211 and the corresponding a plurality of signal bonding pad 236, and many transmission lines 232 are connected between many control lines 212 and the corresponding a plurality of signal bonding pad 236.Thus, each lead can be connected to corresponding chip for driving 240.
Particularly, in fanout area 206, the lead of odd number bar (1,3,5...) is for being electrically connected to the main transmission line 231 of sweep trace 211.And the lead of even number bar (not indicating) is for being electrically connected to the inferior transmission line 232 of control line 212.Each bar main transmission line 231 comprises an impedance adjustment part 233 at least.
As shown in Figure 4, the impedance adjustment part 233 of present embodiment is at least one circuitous circuit, and this circuitous circuit comprises many first line segment 233a and many second line segment 233b.The first line segment 233a extends along first direction D1, and the second line segment 233b extends along second direction D2, and the first line segment 233a is end-to-end with the second line segment 233b is connected (end to end).Wherein, first direction D1 is parallel to the bearing of trend of each main transmission line 231 in fact, and second direction D2 is in fact perpendicular to the bearing of trend of each main transmission line 231.In addition, the length of the first line segment 233a is different from the length of the second line segment 233b, that is the length of the first line segment 233a is less than the length of the second line segment 233b.
In addition, each bar main transmission line 231 also comprises impedance adjustment part 234, be positioned at sweep trace 211 and main transmission line 231 junctions near.Impedance adjustment part 234 is at least one circuitous circuit, and its setting is similar to above-mentioned impedance adjustment part 233, please refer to the explanation of above-mentioned impedance adjustment part 233.Be stressed that the present invention does not limit the position or the layout type of impedance adjustment part 233,234, the embodiment that Fig. 4 illustrated only is wherein a kind of embodiment of the present invention.
In the present embodiment, being positioned at fanout area 206 outermost main transmission lines 231 because line length is the longest, is the lead of impedance maximum, and therefore outermost main transmission line 231 can not need to adopt the mode of circuitous coiling to increase its impedance again.Certainly, in part embodiment, those skilled in the art also can carry out the impedance adjustment and be positioned at fanout area 206 outermost main transmission lines 231 according to circumstances according to actual demand.
In the present embodiment, because main transmission line 231 is adjusted impedance by impedance adjustment part 233, and inferior transmission line 232 is not adjusted impedance, so the resistance difference of 232 of main transmission line 231 and adjacent inferior transmission lines is bigger.The impedance difference that has between at least one main transmission line 231 and contiguous wherein one transmission line 232 is for example greater than 3 ohm (Ω).In part embodiment, the impedance difference of wherein one transmission line 232 of at least one main transmission line 231 and vicinity is for example at least greater than 600 ohm (Ω).But, the impedance difference between adjoining two main transmission lines 231 is then because the design of impedance adjustment part 233 and can be less than 3 ohm (Ω).
For active component array base board 200, the signal transmission quality of all sweep traces 211 is can not difference too big.Therefore, present embodiment is only adjusted the impedance magnitude of main transmission line 231, and the duration of charging of each dot structure 208 is reached unanimity.Particularly, because time transmission line 232 is not adjusted impedance, as long as the live width of inferior transmission line 232 is controlled within the live width that does not break.So the configuration of inferior transmission line 232 can not take space too many in the fanout area 206.In other words, the space of main transmission line 231 configurable impedance adjustment parts 233 has more elasticity and helps to make the transmission quality uniformity more of sweep trace 211.
Furthermore, the tortuous amplitude of the length of impedance adjustment part 233,234 integral body and lead can be looked each bar sweep trace 211 and changed to the distance between the signal bonding pad 236.When sweep trace 211 short more to the distance between the signal bonding pad 236, then the length of impedance adjustment part 233,234 integral body must long more or circuitous tortuous amplitude must be big more.Thus, the transmission quality of different scanning line 211 convergence more.
Fig. 5 is the synoptic diagram of the another kind of fanout area of the present invention.Please refer to Fig. 5, said active element array substrate 200 also can adopt the configuration mode of fanout area 206a to adjust impedance.The difference of fanout area 206a and fanout area 206 is that in the impedance adjustment part 233 of fanout area 206a, the length of the first line segment 233a is greater than the length of the second line segment 233b.Certainly, in other embodiments, the length of the first line segment 233a also can equal the length of the second line segment 233b.That is to say that the present invention does not limit the direction of winding and the layout type of circuitous portion.
Fig. 6 is the synoptic diagram of another fanout area of the present invention.Please refer to Fig. 6, the difference of fanout area 206b and fanout area 206 is that the impedance adjustment part 233 of fanout area 206b has different live widths.In addition, main transmission line 231 can only be made of impedance adjustment part 233.That is to say that the live width of many main transmission lines 231 can be different.
Particularly, the live width of many main transmission lines 231 is to be successively decreased by the center of the lateral fanout area 206b of fanout area 206b, and the live width of many transmission lines 232 is a definite value.Thus, the resistance difference between the different main transmission lines 231 can reduce effectively and make the signal transmission quality trend of sweep trace 211 consistent.In part embodiment, the live width of main transmission line 231 is for example from 5 μ m to 40 μ m.
Fig. 7 is the synoptic diagram of another fanout area of the present invention.Fig. 8 is the diagrammatic cross-section of a-a ' line in Fig. 7.Please refer to Fig. 7 and Fig. 8, the configuration mode of fanout area 206c for example is to adjust impedance in the mode of multilayer line.At this, member identical in fanout area 206c and the above-mentioned fanout area 206 is represented with identical label, no longer repeats herein.
