Please refer to FIG. 1, the foldable display 10 has at least one bending area FA and at least one non-bending area NFA. The foldable display 10 includes: an element array substrate 100, at least one light-emitting element 200, and a driving element 300. The element array substrate 100 has a first surface 101 and a second surface 102 opposite to each other.

請參照圖1，驅動元件300設置在元件陣列基板100的第二表面102，且電性連接至第二導線160，以發送驅動訊號到元件陣列基板100，進而控制發光元件200以顯示各種影像。詳細而言，請參照圖1，驅動元件300可通過第二導線160與第二導電結構140而電性連接到閘極線128，以控制主動元件120的開啟或關閉，進而，控制發光元件200的發光或不發光。1, the driving element 300 is disposed on the second surface 102 of the element array substrate 100 and is electrically connected to the second wire 160 to send driving signals to the element array substrate 100 to control the light emitting element 200 to display various images. In detail, referring to FIG. 1, the driving element 300 can be electrically connected to the gate line 128 through the second wire 160 and the second conductive structure 140 to control the turning on or off of the active element 120, thereby controlling the light emitting element 200 Luminous or non-luminous.

According to other embodiments, the chip can also be bonded to the device array substrate 100 by a chip-on-glass (COG) process, tape automated bonding (TAB), or other methods.

承上述，在圖1的實施例中，位在彎折區域FA的第一孔洞103貫穿了基板110、閘極絕緣層125及層間介電層126，而具有深度H1。位在非彎折區域NFA的第二孔洞104貫穿了基板110及閘極絕緣層125，而具有深度H2，並且，第一孔洞103的深度H1大於第二孔洞104的深度H2。In view of the above, in the embodiment of FIG. 1, the first hole 103 located in the bending area FA penetrates the substrate 110, the gate insulating layer 125 and the interlayer dielectric layer 126, and has a depth H1. The second hole 104 located in the non-bending area NFA penetrates the substrate 110 and the gate insulating layer 125 and has a depth H2, and the depth H1 of the first hole 103 is greater than the depth H2 of the second hole 104.

由於在彎折區域FA的第一孔洞103的深度H1大於在非彎折區域NFA的第二孔洞104的深度H2，也就是說，第一孔洞103中的第一導電結構130的深度H1也大於第二孔洞104中的第二導電結構140的深度H2。因此，當折疊顯示器10被彎折時，在彎折區域FA的較深的第一導電結構130可提供更好的延展性，以有效防止走線的斷裂或是膜層產生裂紋，從而，能夠提升折疊顯示器10的可靠度。Since the depth H1 of the first hole 103 in the bending area FA is greater than the depth H2 of the second hole 104 in the non-bending area NFA, that is, the depth H1 of the first conductive structure 130 in the first hole 103 is also greater than The depth H2 of the second conductive structure 140 in the second hole 104. Therefore, when the foldable display 10 is bent, the deeper first conductive structure 130 in the bending area FA can provide better ductility, so as to effectively prevent wire breakage or film cracks, so that The reliability of the folding display 10 is improved.

並且，第一導電結構130與第二導電結構140可作為訊號連接結構，因此，可使元件陣列基板100的內部的電子元件或線路，能夠電性連接到都設置在第二表面102上的第一導線150與第二導線160。結果是，可增加元件陣列基板100的第一表面101的可利用空間，例如，可設置排列更緊密的發光元件200，而提升影像的解析度。In addition, the first conductive structure 130 and the second conductive structure 140 can be used as signal connection structures.

以下，繼續說明本發明的其他實施例，並且，沿用圖1的實施例的元件標號與相關內容，其中，採用相同的標號來表示相同或近似的元件，並且省略了相同技術內容的說明。關於省略部分的說明可參考圖1的實施例，在以下的說明中不再重述。Hereinafter, the description of other embodiments of the present invention will be continued, and the element numbers and related content of the embodiment of FIG. 1 will be used, wherein the same numbers are used to denote the same or similar elements, and the description of the same technical content is omitted. For the description of the omitted parts, reference may be made to the embodiment of FIG. 1, which will not be repeated in the following description.

圖2是依照本發明一實施例的折疊顯示器(內折顯示器)的剖面示意圖。請參照圖2，在折疊顯示器20中，第一孔洞103a貫穿元件陣列基板100，而第二孔洞104未貫穿元件陣列基板100。2 is a schematic cross-sectional view of a foldable display (inward-folded display) according to an embodiment of the present invention. Please refer to FIG. 2, in the foldable display 20, the first hole 103 a penetrates the device array substrate 100, and the second hole 104 does not penetrate the device array substrate 100.

詳細而言，第一孔洞103a貫穿了基板110、閘極絕緣層125、層間介電層126、閘極線128、及保護層127，另外，第二孔洞104只有貫穿基板110與閘極絕緣層125，因此，以第二表面102為基準，第一孔洞103a的深度H3大於第二孔洞104的深度H2，如此一來，使得第一導電結構130a的深度H3也大於第二導電結構140的深度H2。In detail, the first hole 103a penetrates the substrate 110, the gate insulating layer 125, the interlayer dielectric layer 126, the gate line 128, and the protective layer 127. In addition, the second hole 104 only penetrates the substrate 110 and the gate insulating layer. 125. Therefore, taking the second surface 102 as a reference, the depth H3 of the first hole 103a is greater than the depth H2 of the second hole 104, so that the depth H3 of the first conductive structure 130a is also greater than the depth of the second conductive structure 140 H2.

由於第一孔洞103a貫穿了元件陣列基板100，並且，在第一孔洞103a內設置了深度H3較深的第一導電結構130a，所以，在對於彎折區域FA進行彎折時，深度H3較深的第一導電結構130a能夠更有效地防止閘極絕緣層125、層間介電層126等產生裂紋，且能避免第一導線150斷線。Since the first hole 103a penetrates the element array substrate 100, and the first conductive structure 130a with a relatively deep depth H3 is provided in the first hole 103a, when the bending area FA is bent, the depth H3 is relatively deep The first conductive structure 130a can more effectively prevent the gate insulating layer 125, the interlayer dielectric layer 126, etc. from cracking, and can prevent the first wire 150 from breaking.

並且，第一導電結構130a與第二導電結構140作為訊號連接結構，可使得第一導線150與第二導線160都能夠設置於第二表面102，如此，可增加第一表面101的可使用空間，使得發光元件200能夠在第一表面101進行更緊密的排列，進而，能夠提升影像的解析度。In addition, the first conductive structure 130a and the second conductive structure 140 are used as signal connection structures, so that both the first wire 150 and the second wire 160 can be disposed on the second surface 102, so that the usable space of the first surface 101 can be increased , So that the light-emitting elements 200 can be more closely arranged on the first surface 101, and further, the resolution of the image can be improved.

請繼續參照圖2，在本發明一實施例中，折疊顯示器20可以是內折顯示器。從元件陣列基板100的垂直投影方向觀看，第一孔洞103a位於第一表面101的孔徑D11，小於第一孔洞103a位於第二表面102的孔徑D21。需說明的是，本文所述的「元件陣列基板100的垂直投影方向」是指：垂直於元件陣列基板100的第一表面101或第二表面102的方向。Please continue to refer to FIG. 2. In an embodiment of the present invention, the foldable display 20 may be an inwardly foldable display. Viewed from the vertical projection direction of the element array substrate 100, the first hole 103a is located on the first surface 101 with an aperture D11 which is smaller than the first hole 103a located on the second surface 102 of the aperture D21. It should be noted that the “vertical projection direction of the element array substrate 100” mentioned herein refers to a direction perpendicular to the first surface 101 or the second surface 102 of the element array substrate 100.

另外，折疊顯示器20還包括：至少一第三導線170，第三導線170設置在第一表面101且鄰接第一孔洞103a，從元件陣列基板100的垂直投影方向觀看，第三導線170位於第一表面101的線寬W3，小於第一導線150位於第二表面102的線寬W1。In addition, the foldable display 20 further includes: at least one third wire 170. The third wire 170 is disposed on the first surface 101 and adjacent to the first hole 103a. When viewed from the vertical projection direction of the element array substrate 100, the third wire 170 is located on the first surface. The line width W3 of the surface 101 is smaller than the line width W1 of the first wire 150 on the second surface 102.

當對於折疊顯示器20的彎折區域FA進行內折，而呈現U字形的彎折形狀時，折疊顯示器20的內部彎折區域會承受壓縮力(compressive force)，而折疊顯示器20的外部彎折區域會承受拉伸力(tensile force)。利用第一孔洞103a的上述孔徑D11、D21的尺寸設計，以及第一導線150的上述線寬W1與第三導線170的上述線寬W3的尺寸設計，使得位於第一孔洞103a內的第一導電結構130a、第一導線150與第三導線170的整體結構，能夠平衡折疊顯示器20在進行內折時所產生的壓縮力與拉伸力，從而，能夠增加彎折區域FA的結構強度，並提升折疊顯示器20的可靠度。When the bending area FA of the foldable display 20 is folded inward and presents a U-shaped bending shape, the inner bending area of the foldable display 20 will bear compressive force, and the outer bending area of the foldable display 20 Will bear tensile force (tensile force). Using the size design of the above-mentioned apertures D11 and D21 of the first hole 103a, and the above-mentioned line width W1 of the first wire 150 and the above-mentioned line width W3 of the third wire 170, the first conductive wire located in the first hole 103a The overall structure of the structure 130a, the first wire 150 and the third wire 170 can balance the compressive force and the tensile force generated by the folding display 20 when it is folded inward, thereby increasing the structural strength of the bending area FA and improving The reliability of the folding display 20.

在本實施例中，第三導線170使用的材料可以與第一導線150或第二導線160相同，亦即，使用延展性高的導電材料。另外，第三導線170也可以使用金屬材料、合金、金屬材料的氮化物、金屬材料的氧化物、金屬材料的氮氧化物、或是金屬材料與其它導電材料的堆疊層，但本發明不限於此。In this embodiment, the material used for the third wire 170 may be the same as that of the first wire 150 or the second wire 160, that is, a conductive material with high ductility is used. In addition, the third wire 170 can also use metal materials, alloys, nitrides of metal materials, oxides of metal materials, oxynitrides of metal materials, or stacked layers of metal materials and other conductive materials, but the present invention is not limited to this.

圖3是依照本發明一實施例的折疊顯示器的剖面示意圖。請參照圖3，在折疊顯示器30中，元件陣列基板100具有多個的第一孔洞103a、103b，這些第一孔洞103a、103b的深度H3、H4，從該彎折區域FA的中心線L往外遞減，亦即，深度H4會小於深度H3。FIG. 3 is a schematic cross-sectional view of a foldable display according to an embodiment of the invention. 3, in the foldable display 30, the device array substrate 100 has a plurality of first holes 103a, 103b, and the depths H3, H4 of the first holes 103a, 103b are outward from the center line L of the bending area FA Decrease, that is, the depth H4 will be smaller than the depth H3.

舉例而言，請參照圖3，在彎折區域FA的中心線L的位置，設置有貫穿了元件陣列基板100的第一孔洞103a，具有深度H3；從位於中心線L的第一孔洞103a，朝向離開中心線L的位置，還設置有貫穿了基板110、閘極絕緣層125及層間介電層126的第一孔洞103b，具有深度H4；並且，使得深度H4小於深度H3。經由第一孔洞103a、103b的深度H3、H4從彎折區域FA的中心線L往外遞減的設計，可使得第一導電結構130a、130b的深度H3、H4也從彎折區域FA的中心線L往外遞減，如此，可有效地提高彎折區域FA的結構強度，以在圖3的水平方向上，對於折疊顯示器30進行彎折時所產生的應力進行良好的平衡。For example, referring to FIG. 3, at the position of the center line L of the bending area FA, a first hole 103a penetrating the element array substrate 100 is provided with a depth H3; from the first hole 103a located on the center line L, Toward a position away from the center line L, a first hole 103b penetrating through the substrate 110, the gate insulating layer 125 and the interlayer dielectric layer 126 is also provided, and has a depth H4; and the depth H4 is made smaller than the depth H3. The depth H3, H4 of the first holes 103a, 103b is gradually reduced from the center line L of the bending area FA, so that the depths H3, H4 of the first conductive structure 130a, 130b are also from the center line L of the bending area FA. In this way, the structural strength of the bending area FA can be effectively improved, so as to balance the stress generated when the folded display 30 is bent in the horizontal direction of FIG. 3.

在圖3的實施例中，在彎折區域FA中，僅繪示了一個第一孔洞103a及位於兩側的兩個第一孔洞103b，使這些第一孔洞103a、103b的深度H3、H4，從彎折區域FA的中心線L往外遞減。然而，在此實施例中，也可以設置多個(三個以上)的第一孔洞103a、103b，且使多個第一孔洞103a、103b的深度，從彎折區域FA的中心線L往外遞減。在此實施例中，並不限定第一孔洞103a、103b的數量。In the embodiment of FIG. 3, in the bending area FA, only one first hole 103a and two first holes 103b on both sides are shown, so that the depths H3, H4 of these first holes 103a, 103b are Decrease outward from the center line L of the bending area FA. However, in this embodiment, multiple (more than three) first holes 103a, 103b can also be provided, and the depth of the multiple first holes 103a, 103b decreases from the center line L of the bending area FA to the outside. . In this embodiment, the number of the first holes 103a and 103b is not limited.

此外，請參照圖3，同樣地，在非彎折區域NFA中，設置有第二孔洞104以及位於第二孔洞104中的第二導電結構140，第二孔洞104具有深度H5。可看到，深度H3大於深度H4，且深度H4大於深度H5。此深度漸減的設計，可以在圖3的水平方向上，對於折疊顯示器30進行彎折時所產生的應力進行良好的平衡。In addition, referring to FIG. 3, similarly, in the non-bending area NFA, a second hole 104 and a second conductive structure 140 located in the second hole 104 are provided, and the second hole 104 has a depth H5. It can be seen that the depth H3 is greater than the depth H4, and the depth H4 is greater than the depth H5. This gradually decreasing depth design can balance the stress generated when the foldable display 30 is bent in the horizontal direction of FIG. 3.

以下配合圖4A至圖4B說明本發明折疊顯示器的彎折區域中，第一孔洞的孔徑變化及第一導線的線寬變化。圖4A是依照本發明一實施例的折疊顯示器的元件陣列基板的第二表面的正視圖。請參照圖4A，從元件陣列基板100的垂直投影方向觀看該第二表面102，元件陣列基板100在彎折區域FA具有多個的第一孔洞103及其周圍的具有方形輪廓的第一導線150，而且，這些第一孔洞103可以具有相同的孔徑D。The following describes the change in the diameter of the first hole and the change in the line width of the first wire in the bending area of the folded display of the present invention in conjunction with FIGS. 4A to 4B. 4A is a front view of the second surface of the element array substrate of the foldable display according to an embodiment of the present invention. Referring to FIG. 4A, the second surface 102 is viewed from the vertical projection direction of the element array substrate 100. The element array substrate 100 has a plurality of first holes 103 in the bending area FA and a first wire 150 with a square outline around it. Moreover, these first holes 103 may have the same diameter D.

圖4B是依照本發明一實施例的折疊顯示器的元件陣列基板的第二表面的正視圖。請參照圖4B，元件陣列基板100也可具有多個的第一孔洞103a、103b、103c、103d，而且，從元件陣列基板100的垂直投影方向觀看該第二表面102，這些第一孔洞103a~103d的孔徑Da~Dd，從彎折區域FA的中心線L往外遞減。4B is a front view of the second surface of the element array substrate of the foldable display according to an embodiment of the present invention. 4B, the device array substrate 100 may also have a plurality of first holes 103a, 103b, 103c, 103d, and when viewed from the vertical projection direction of the device array substrate 100 on the second surface 102, these first holes 103a~ The apertures Da~Dd of 103d decrease from the center line L of the bending area FA to the outside.

舉例而言，請參照圖4B，在彎折區域FA的中心線L的位置的第一孔洞103a，具有孔徑Da。從位於中心線L的第一孔洞103a，朝向離開中心線L的位置，依序設置了：具有孔徑Db的第一孔洞103b、具有孔徑Dc的第一孔洞103c以及具有孔徑Dd的第一孔洞103d，而且，孔徑Da、Db、Dc、Dd依序遞減，即Da>Db>Dc>Dd。經由第一孔洞103a~103d的孔徑Da~Dd從彎折區域FA的中心線L往外遞減的設計，可提升彎折區域FA的結構強度。進而，可以在圖4B的水平方向上，對於折疊顯示器進行彎折時所產生的應力進行良好的平衡。For example, referring to FIG. 4B, the first hole 103a at the position of the center line L of the bending area FA has an aperture Da. From the first hole 103a located on the center line L to a position away from the center line L, a first hole 103b with a hole diameter Db, a first hole 103c with a hole diameter Dc, and a first hole 103d with a hole diameter Dd are sequentially arranged And, the pore diameters Da, Db, Dc, Dd decrease in order, namely Da>Db>Dc>Dd. The design in which the apertures Da~Dd of the first holes 103a~103d decrease from the center line L of the bending area FA to the outside can increase the structural strength of the bending area FA. Furthermore, in the horizontal direction of FIG. 4B, the stress generated when the folded display is bent can be well balanced.

另外，請再參照圖4B，該元件陣列基板100具有多個第一孔洞103a~103d，從元件陣列基板100的垂直投影方向觀看，元件陣列基板100具有多個鑽孔區DR，第一孔洞103a~103d的位置對應於這些鑽孔區DR，其中，第一導線150在這些鑽孔區DR的線寬Wa、Wb、Wc、Wd，從彎折區域FA的中心線L往外遞減。In addition, referring to FIG. 4B again, the device array substrate 100 has a plurality of first holes 103a-103d. Viewed from the vertical projection direction of the device array substrate 100, the device array substrate 100 has a plurality of drilling regions DR, and the first holes 103a The position of ~103d corresponds to these drilling areas DR, where the line widths Wa, Wb, Wc, Wd of the first wire 150 in these drilling areas DR decrease from the center line L of the bending area FA to the outside.

請參照圖4B，在從彎折區域FA的中心線L往兩側的方向上，第一導線150在這些鑽孔區DR中依序具有線寬Wa、Wb、Wc、Wd，其中，線寬Wa、Wb、Wc、Wd依序遞減，即Wa>Wb>Wc>Wd。經由第一導線150在這些鑽孔區DR中的線寬Wa、Wb、Wc、Wd從彎折區域FA的中心線L往外遞減的設計，可提升彎折區域FA的結構強度。進而，可以在圖4B的水平方向上，對於折疊顯示器進行彎折時所產生的應力進行良好的平衡。Referring to FIG. 4B, in the direction from the center line L of the bending area FA to both sides, the first wire 150 has line widths Wa, Wb, Wc, and Wd in these drilling areas DR in sequence, wherein the line widths Wa, Wb, Wc, and Wd decrease in order, that is, Wa>Wb>Wc>Wd. The design in which the line widths Wa, Wb, Wc, and Wd of the first wire 150 in these drilling areas DR decrease from the center line L of the bending area FA to the outside can increase the structural strength of the bending area FA. Furthermore, in the horizontal direction of FIG. 4B, the stress generated when the folded display is bent can be well balanced.

此外，請再參照圖4B，從元件陣列基板100的垂直投影方向觀看，元件陣列基板100具有鑽孔區DR與非鑽孔區NDR，第一孔洞103a~103d的位置對應於鑽孔區DR，其中，第一導線150在鑽孔區DR的線寬Wa、Wb、Wc、Wd，大於第一導線150在非鑽孔區NDR的線寬We。經由第一導線150在鑽孔區DR的線寬Wa~Wd，大於第一導線150在非鑽孔區NDR的線寬We的設計，可有效地提高第一導線150在進行彎折時的可靠度。In addition, referring to FIG. 4B again, viewed from the vertical projection direction of the element array substrate 100, the element array substrate 100 has a drilled area DR and a non-drilled area NDR. The positions of the first holes 103a to 103d correspond to the drilled area DR. The line widths Wa, Wb, Wc, and Wd of the first wire 150 in the drilling area DR are larger than the line width We of the first wire 150 in the non-drilling area NDR. The design that the line width Wa~Wd of the first wire 150 in the drilling area DR is larger than the line width We of the first wire 150 in the non-drilling area NDR can effectively improve the reliability of the first wire 150 during bending Spend.
