Fig. 1 is the synoptic diagram of the display device of one embodiment of the invention, and Fig. 2 A is the wherein partial schematic diagram of a lead of the display device of Fig. 1, and Fig. 2 B then is the cut-away view of the lead of Fig. 2 A.Please be simultaneously with reference to figure 1, Fig. 2 A and Fig. 2 B, the display device 100 of present embodiment comprises a display panel 110 and a conducting resinl 120.Display panel 110 has the dielectric layer 114 that many leads 112 and cover these leads 112.
In the present embodiment, display panel 110 has a viewing area P1 and and is positioned at the outer circuit bonding land P2 of viewing area P1, and the lead 112 that present embodiment is lifted is leads of extending to circuit bonding land P2 with the P1 from the viewing area as illustrating, and non-ly is limited to this.In other embodiment, lead 112 also can be sweep trace (scanline) or the data line (data line) in the general reference driving component array district (active device array area), or the lead in the P2 of circuit bonding land.In addition, above-mentioned display panel 110 for example be with display panels as illustrating, non-as limit.In other embodiment, display panel 110 also can be organic electric-excitation luminescent displaying panel, plasma display, electrophoretic display panel or Electrowetting display panel.
In display panel 110; At least one of them has a disconnection defect 112a to above-mentioned lead 112; The dielectric layer 114 that is covered on the lead 112 then has repair contact windows (repair vias) 114a of at least three positions corresponding to disconnection defect 112a, shown in Fig. 2 A and Fig. 2 B.Specifically, when having disconnection defect 112a as if lead 112, then represent lead 112 to present open-circuit condition, this moment, electric signal just can't lean on this lead 112 to transmit.That is to say that the lead 112 with disconnection defect 112a can be divided into one first line segment L1 and one second line segment L2, wherein the first line segment L1 and the second line segment L2 can be separated from one another in disconnection defect 112a place like what illustrated among Fig. 2 A and Fig. 2 B.Certainly, Fig. 2 A is that to have a disconnection defect 112a with lead 112 be that example describes, but the present invention is not as limit.In other words, under other possible situation, lead 112 possibly have at least two disconnection defects simultaneously, and then is distinguished at least three line segments.
The lead 112 that is illustrated in Fig. 2 A and Fig. 2 B is divided under the situation of the first line segment L1 and the second line segment L2 by disconnection defect 112a; Above-mentioned repair contact windows 114a comprises m the first repair contact windows W1 and n the second repair contact windows W2; Wherein the individual first repair contact windows W1 of m exposes the first line segment L1 of lead 112, and n the second repair contact windows W2 exposes the second line segment L2.In present embodiment, because the quantity of repair contact windows 114a is more than or equal to three, so m+n >=3.
Particularly; The quantity of above-mentioned repair contact windows 114a is to be that example describes with 12 of being illustrated like Fig. 2 A and Fig. 2 B; But the present invention is not exceeded with graphic; In other possible embodiment, the user can and need and suitably adjusts the quantity of repair contact windows 114a according to its required design.For example, above-mentioned m, the restrictive condition of n can be m=1, and n＞1, or are the performances of m＞1 and n＞1, and this partly looks closely user's demand and design and decides.It is noted that the number needs of repair contact windows 114a just can reach like advantage mentioned in the subsequent paragraph more than or equal to more than three.
Please continue with reference to figure 2A and Fig. 2 B; The repair contact windows 114a of present embodiment has identical depth H 1 or has multiple different depth H1; And the depth H 1 of part repair contact windows 114a is greater than the thickness D1 of dielectric layer 114 at least, and therefore above-mentioned lead 112 with disconnection defect 112a just can be exposed by the repair contact windows 114a of dielectric layer 114.Particularly; If repair contact windows 114a forms with the laser beam drilling processing procedure; Then the energy through the adjustment laser beam just can form the repair contact windows 114a with different depth H1, and the visual user's that puts in order the demand of repair contact windows 114a that wherein has different depth H1 is different with design.Explanation for ease, present embodiment are can describe according to specific putting in order with putting in order of repair contact windows 114a, and it is explained as follows, but the present invention is not as limit.
In detail, repair contact windows 114a is used for repairing lead 112 to have the situation of disconnection defect 112a so that lead 112 can continue conducting electrical signals, so the position of repair contact windows 114a usually can be corresponding to disconnection defect 112a.In the example that Fig. 2 A and Fig. 2 B are illustrated; The mode that forms the repair contact windows 114a with different depth H1 with the laser beam drilling processing procedure can apply stronger laser energy prior to the part near disconnection defect 112a; Then reduce laser energy according to direction away from disconnection defect 112a; Like this then can make repair contact windows 114a have bigger depth H 1 near disconnection defect 112a; And make repair contact windows 114a can have small depth away from disconnection defect 112a, shown in Fig. 2 A and Fig. 2 B.In other words, these repair contact windows 114a that has different depth H 1 can arrange along the bearing of trend of the lead 112 with disconnection defect 112a place.
In another example, these repair contact windows 114a with different depth H 1 might not be according to the arrangement mode that is illustrated like Fig. 2 A and Fig. 2 B.For instance; Also can apply more weak laser energy in part and toward away from increasing laser energy on the direction of disconnection defect 112a gradually near disconnection defect 112a; Having the more shallow repair contact windows 114a of depth H 1, and has the darker repair contact windows 114a of depth H 1 in forming away from disconnection defect 112a in forming near disconnection defect 112a place.In addition; The putting in order except can being to adopt the above-mentioned arrangement mode of repair contact windows 114a with different depth H1; It also can be out of order arrangement; That is to say that hobby that the arrangement mode of the repair contact windows 114a of different depth H1 can the user or demand and decide non-ly only limit to above-mentioned way of example.
Need to prove; Above-mentioned all is to have different depth H 1 as explanation with repair contact windows 114a; In other possible embodiment, the depth H 1 of above-mentioned repair contact windows 114a also can be all identical, or part is identical; This partly looks closely user's demand and design and decides, and the present invention is not as limit.
In addition, can make that then the lead 112 with disconnection defect 112a place is identical in fact by the area A 1 that each repair contact windows 114a is exposed if suitably adjust the width of laser beam, shown in Fig. 2 A and Fig. 2 B.In another embodiment; It also can be inequality having the area A 1 that the lead 112 at disconnection defect 112a place exposed by each repair contact windows 114a; Or the part same section is different, and present embodiment is identical as for example with area A 1, but the present invention is not as limit.Need to prove that the depth H of above-mentioned repair contact windows 114a 1 and area A 1 can be with reference to above-mentioned explanations, and do suitable combination arbitrarily.For instance; The depth H 1 of repair contact windows 114a can be all identical, to be all difference or part same section different; And the arrangement mode that forms repair contact windows 114a can be to adopt aforesaid series arrangement or out of order arrangement; And that the area A 1 of repair contact windows 114a can be is identical, difference or part same section are different, and this partly looks closely the user according to its demand and can adjust arbitrarily, and above-mentioned being merely illustrates.
In addition; In order more to clearly demonstrate the technical characterictic of present embodiment; The thickness of dielectric layer 114 for example is to be defined as D1, has the lead 112 at disconnection defect 112a place and the thickness summation of dielectric layer 114 and then is defined as D2, thus; In order to make dielectric layer 114 can suitably expose lead 112, the numerical value of the depth H 1 of the above-mentioned repair contact windows of part at least 114a is between D1 and D2.In Fig. 2 B, part can be less than D1 away from the depth H 1 of the repair contact windows W1 of disconnection defect 112a, and part can equal D2 in fact near the depth H 1 of the repair contact windows 114a of disconnection defect 112a.
Please continue with reference to figure 2A and Fig. 2 B; Conducting resinl 120 is disposed at disconnection defect 112a place; And owing to lead 112 can be exposed by the repair contact windows 114a of dielectric layer 114, so conducting resinl 120 just can electrically connect with the lead with disconnection defect 112a place 112 through these repair contact windows 114a.
Particularly because lead 112 has disconnection defect 112a, just so lead 112 can be divided into the first line segment L1 that illustrates like Fig. 2 A and Fig. 2 B and the second line segment L2 and break, thereby cause electric signal on lead 112, to transmit.Transmit electric signal in order to make lead 112 continued conducting; Therefore can expose the first line segment L1 through making the first repair contact windows W1 that is positioned on the first line segment L1; And make the second repair contact windows W1 that is positioned on the second line segment L2 expose the first line segment L1; Thus; When conducting resinl 120 is disposed at disconnection defect 112a place and when neighbouring, conducting resinl 120 just can contact with the second line segment L2 with the first line segment L1 respectively with the second repair contact windows W2 through the first repair contact windows W1 respectively, thereby the first line segment L1 and the second line segment L2 are electrically connected through conducting resinl 120.
Specifically, in repair contact windows 114a, the quantity summation of the first repair contact windows W1 and the second repair contact windows W2 is at least more than three.Tracing it to its cause just is, if the quantity of repair contact windows 114a when to be three or three above, then can reduce the time that forms the repair contact windows desired depth with the test of laser beam drilling processing procedure; Be at least three when above if the first repair contact windows W1 and the second repair contact windows W2 successfully expose the quantity summation of lead 112, more can reduce the resistance value of conducting resinl 120 and the first line segment L1 and the second line segment L2.Careful; Generally in order on dielectric layer, to form to expose the repair contact windows of first line segment and second line segment time; Need to adjust the energy of laser beam according to the thickness of dielectric layer; When avoiding laser beam energy excessive and first line segment and second line segment are punched, or avoid laser beam energy too small and do not expose first line segment and second line segment.In other words, in order to form the repair contact windows that can expose first line segment and second line segment accurately, need test out required suitable laser beam energy repeatedly, thereby can increase the test duration of processing procedure.
The quantity of reviewing the repair contact windows 114a of present embodiment is more than three; And by lay respectively at first and second repair contact windows W1 on the first line segment L1 and the second line segment L2, the depth H 1 of W2 can be found along the technical characterictic that diminishes gradually away from the direction at disconnection defect 112a place; Present embodiment can impose on stronger laser beam energy to form depth H 1 darker first and second repair contact windows W1, W2 prior to being close to disconnection defect 112a place, and wherein this depth H 1 can be above-mentioned thickness D2.Then, upwards reduce laser beam energy one by one toward writing out a prescription again, and form different first and second repair contact windows W1, the W2 of the degree of depth, illustrate like Fig. 2 B away from disconnection defect 112a.In other words; Present embodiment be through the adjustment laser beam the energy size repeatedly to form the different repair contact windows of a plurality of degree of depth; Wherein part repair contact windows 114a can expose the first line segment L1 and the second line segment L2 respectively at least, and then makes that first line segment and second line segment just can the conductings through conducting resinl when conducting resinl 120 was disposed at dielectric layer 114.Therefore, the display device 100 that has an above-mentioned repair contact windows 114a structure just can reduce it and test the required time of processing procedure.
In display device 100, the distribution range of conducting resinl 120 can contain above-mentioned repair contact windows 114a, and the material of conducting resinl 120 can be heat curing conducting resinl or photo-curable conductive adhesive.
Above-mentioned Fig. 2 A and Fig. 2 B all be with 12 repair contact windows 114a as illustrating, in another example, the quantity of repair contact windows 114a also can be three, illustrates like Fig. 2 C.In Fig. 2 C; Because the quantity of repair contact windows 114a is three; And all expose the first line segment L1 and the second line segment L2, therefore, when conducting resinl 120 is disposed at disconnection defect 112a place; Conducting resinl 120 can be through repair contact windows 114a and contacting with the second line segment L2 with the first line segment L1 respectively, thereby win line segment L1 and the second line segment L2 can be electrically connected through conducting resinl 120.In addition; Because repair contact windows 114a all exposes lead 112, so the contact area of conducting resinl 120 and lead 112 just can increase, thus; Except the problem of the disconnection defect of having repaired lead 112, also can promote lead 112 and resistance value reduced by the conductivity after repairing.
In an embodiment again, repair contact windows 114a also can be four, shown in Fig. 2 D.In Fig. 2 D; Which kind of laser energy two second repair contact windows W2 that are positioned at second line segment can be used to test out earlier and can make second line segment be exposed out and can the second line segment L2 not destroyed; Then on first line segment, form two first repair contact windows W1 with the laser energy that can expose second line segment again, shown in Fig. 2 D.Likewise; Because repair contact windows 114a has at least three to expose lead 112; Therefore conducting resinl 120 just can increase with the contact area of lead 112; Thus, except the problem of the disconnection defect of having repaired lead 112, also can promote lead 112 and resistance value reduced by the conductivity after repairing.
Above-mentioned all is to have disconnection defect 112a as illustrating with a lead 112, below will illustrate if two leads are when all having disconnection defect the example that lead 112 possibly repaired at least.
