於本發明之多個實施方式中，各個第一延伸段154-1、154-Z的延伸線與第一連接段152的延伸線EL2具有夾角，此夾角隨著遠離第一連接段152而逐漸變大。舉例而言，第一延伸段154-1的延伸線與第一連接段152的延伸線EL2具有夾角Aa，第一延伸段154-Z的延伸線與第一連接段152的延伸線EL2具有夾角Az。由鄰近第一連接段152至遠離第一連接段152，夾角逐漸變大，例如夾角Aa以及夾角Az依序變大。如此一來，可以在有限的空間內，在盡量維持訊號線150之第一延伸段154的寬度的情況下，達到轉線的目的。換言之，特定實施例中，在第二延伸段156之前的第一延伸段154係朝特定順時針或逆時針方向延伸，而不會有朝兩個方向延伸情形，進而降低了阻抗過高的可能。 In various embodiments of the present invention, the extension line of each of the first extension sections 154-1 and 154-Z and the extension line EL2 of the first connection section 152 have an included angle, and the included angle gradually decreases as it moves away from the first connection section 152. Get bigger. For example, the extension line of the first extension segment 154-1 and the extension line EL2 of the first connection segment 152 have an angle Aa, and the extension line of the first extension segment 154-Z and the extension line EL2 of the first connection segment 152 have an angle Az. From the vicinity of the first connection section 152 to the distance from the first connection section 152, the included angle gradually increases, for example, the included angle Aa and the included angle Az sequentially increase. In this way, the purpose of transferring the line can be achieved in a limited space while maintaining the width of the first extension 154 of the signal line 150 as much as possible. In other words, in a specific embodiment, the first extension section 154 before the second extension section 156 extends in a specific clockwise or counterclockwise direction without extending in two directions, thereby reducing the possibility of excessive impedance. .

於部分實施方式中，第一延伸段154-Z實質平行於第一側邊S1，而使夾角Az為90度。在此，第一延伸段154-Z 為最遠離第一連接段152之第一延伸段154。換句話說，最遠離第一連接段152之第一延伸段154實質平行於第一側邊S1。至此，可以將訊號線150由垂直方向轉為平行方向，此平行方向有利於蝕刻光罩，以便訊號線150形成過程中的圖案化。 In some embodiments, the first extension 154-Z is substantially parallel to the first side S1, so that the included angle Az is 90 degrees. Here, the first extension section 154-Z is the first extension section 154 farthest from the first connection section 152. In other words, the first extension section 154 furthest from the first connection section 152 is substantially parallel to the first side S1. At this point, the signal line 150 can be changed from a vertical direction to a parallel direction. This parallel direction is advantageous for etching the photomask so that the signal line 150 can be patterned during the formation process.

另一方面，於此，第二延伸段156的延伸線與第一延伸段154的延伸線EL2的夾角Ba小於第一延伸段154-Z的延伸線與第一延伸段154的延伸線EL2的夾角Az。在此繪示延伸線EL2’以具體標示夾角Ba的範圍，其中延伸線EL2’平行延伸線EL2。如此一來，可以在有限的空間內，在盡量維持訊號線150之第二延伸段156的寬度的情況下，達到轉線的目的。至此，可以將訊號線150由平行方向轉為垂直方向，以電性耦接閘極驅動器142。 On the other hand, the angle Ba between the extension line of the second extension section 156 and the extension line EL2 of the first extension section 154 is smaller than that of the extension line of the first extension section 154-Z and the extension line EL2 of the first extension section 154. The included angle Az. The extension line EL2 'is shown here to specifically indicate the range of the included angle Ba. The extension line EL2' is parallel to the extension line EL2. In this way, the purpose of transferring the line can be achieved in a limited space while maintaining the width of the second extension 156 of the signal line 150 as much as possible. So far, the signal line 150 can be turned from a parallel direction to a vertical direction, and the gate driver 142 can be electrically coupled.

於部分實施方式中，每一第一延伸段154(例如第一延伸段154-1、第一延伸段154-Z)的至少一側邊為直線，而使第一延伸段154整體為一節節分明的轉線。雖然於此僅以二個第一延伸段154-1、154-Z例示，但不應以此限制本發明之範圍，於其他實施方式中，可以設置三個以上的第一延伸段。同樣地，於部分實施方式中，每一第二延伸段156的至少一側邊為直線，而使第二延伸段156整體為一節節分明的轉線。雖然於此僅例示單個第二延伸段156，但不應以此限制本發明之範圍，於其他實施方式中，可以設置二個以上的第二延伸段，後續將再提供具體的敘述。應了解到，不應以直線側邊此限制本發明之範圍，於其他實施方式中，第一延伸段154以及/或第二延伸段156可以是曲線。 In some embodiments, at least one side of each first extension segment 154 (eg, the first extension segment 154-1, the first extension segment 154-Z) is a straight line, so that the first extension segment 154 is divided into sections as a whole. Bright turn. Although only two first extension sections 154-1 and 154-Z are exemplified here, the scope of the present invention should not be limited in this way. In other embodiments, more than three first extension sections may be provided. Similarly, in some embodiments, at least one side of each second extension segment 156 is a straight line, so that the second extension segment 156 as a whole is a distinct turning line. Although only a single second extension section 156 is exemplified here, the scope of the present invention should not be limited in this way. In other embodiments, more than two second extension sections may be provided, and a detailed description will be provided later. It should be understood that the scope of the present invention should not be limited by straight sides. In other embodiments, the first extension segment 154 and / or the second extension segment 156 may be curved.

於本發明之多個實施方式中，顯示面板100可包含遮光層LS(參考第3圖)，設置於第一基板110上，以定義顯示區DA。具體而言，遮光層LS可具有開口，而露出顯示區DA且遮蔽顯示區DA以外的區域，從第1圖與第2圖的圖面方向來看，第一側邊S1以及第二側邊S2即為遮光層LS的側邊(例如遮光層LS的開口的邊緣)。於此，從第1圖與第2圖的圖面方向來看，第一側邊S1的延伸線以及第二側邊S2的延伸線EL1可以將顯示面板100劃分為四個象限，所稱「顯示區DA之第一側邊S1的外側」係指第一象限，所稱「顯示區DA之第二側邊S2的外側」係指第三象限，所稱「顯示區DA」係指第四象限。 In various embodiments of the present invention, the display panel 100 may include a light shielding layer LS (refer to FIG. 3), which is disposed on the first substrate 110 to define a display area DA. Specifically, the light-shielding layer LS may have an opening to expose the display area DA and shield areas other than the display area DA. Viewed from the drawing directions of FIGS. 1 and 2, the first side S1 and the second side S2 is the side of the light shielding layer LS (for example, the edge of the opening of the light shielding layer LS). Here, from the drawing direction of FIGS. 1 and 2, the extension line of the first side S1 and the extension line EL1 of the second side S2 can divide the display panel 100 into four quadrants. The outside of the first side S1 of the display area DA "refers to the first quadrant, the" outside of the second side S2 of the display area DA "refers to the third quadrant, and the" display area DA "refers to the fourth Quadrant.

第3圖為沿第2圖之線3A-3B以及線3B-3C的剖面示意圖。同時參考第2圖與第3圖。於部分實施方式中，顯示面板100更包含輔助訊號線150A以及絕緣層170。絕緣層170設置於訊號線150與輔助訊號線150A之間，其厚度大約為2000埃至6000埃，例如大約4000埃。輔助訊號線150A設置於訊號線150上，且於本實施方式中，訊號線150之第一延伸段154-Z具有受到輔助訊號線150A覆蓋的第一部分P1以及不受到輔助訊號線150A覆蓋的第二部分P2。於部分實施方式中，絕緣層170具有第一通孔172以及第二通孔174，第一通孔172對應訊號線150之第一連接段152，第二通孔174對應訊號線150之第一延伸段154-Z的第一部分P1。於此，顯示面板100更包含導電膠210，設置於訊號線150之第一連接段152上，導電膠210填入第二通孔174中，使得輔助訊號線150A透過絕緣層170之第一通孔172與第二通孔174電性耦接訊號線150。如此一來，儘管訊號線150的第一延伸段154寬度較窄，透過輔助訊號線150A的設置可以降低訊號傳遞的電阻，相當於增加訊號傳遞路徑中截面積大小，並避免因為而使電阻過高而容易產生高溫的情況。 FIG. 3 is a schematic cross-sectional view taken along lines 3A-3B and 3B-3C of FIG. 2. Refer to Figures 2 and 3 at the same time. In some embodiments, the display panel 100 further includes an auxiliary signal line 150A and an insulating layer 170. The insulating layer 170 is disposed between the signal line 150 and the auxiliary signal line 150A, and has a thickness of about 2000 Angstroms to 6000 Angstroms, for example, about 4000 Angstroms. The auxiliary signal line 150A is disposed on the signal line 150. In this embodiment, the first extension 154-Z of the signal line 150 has a first portion P1 covered by the auxiliary signal line 150A and a first portion P1 not covered by the auxiliary signal line 150A. Two parts P2. In some embodiments, the insulating layer 170 has a first through hole 172 and a second through hole 174. The first through hole 172 corresponds to the first connection section 152 of the signal line 150, and the second through hole 174 corresponds to the first of the signal line 150. The first portion P1 of the extension 154-Z. Here, the display panel 100 further includes a conductive adhesive 210 disposed on the first connection section 152 of the signal line 150. The conductive adhesive 210 is filled in the second through hole 174, so that the auxiliary signal line 150A passes through the first pass of the insulating layer 170. The hole 172 and the second through hole 174 are electrically coupled to the signal line 150. In this way, although the width of the first extension 154 of the signal line 150 is narrow, the resistance of the signal transmission can be reduced by setting the auxiliary signal line 150A, which is equivalent to increasing the size of the cross-sectional area in the signal transmission path, and avoiding excessive resistance due to this. High and prone to high temperature.

於此，輔助訊號線150A具有開口150B，對應絕緣層170之第一通孔172，導電膠210填入開口150B與第一通孔172中。軟性電路板160具有接合墊162。至此，軟性電路板160之接合墊162透過導電膠210而電性耦接訊號線150以及輔助訊號線150A。如此一來，電路板300(參考第1圖)上的元件可以透過軟性電路板160電性耦接基板110上的元件。 Here, the auxiliary signal line 150A has an opening 150B corresponding to the first through hole 172 of the insulating layer 170, and the conductive adhesive 210 is filled in the opening 150B and the first through hole 172. The flexible circuit board 160 includes a bonding pad 162. So far, the bonding pad 162 of the flexible circuit board 160 is electrically coupled to the signal line 150 and the auxiliary signal line 150A through the conductive adhesive 210. In this way, the components on the circuit board 300 (refer to FIG. 1) can be electrically coupled to the components on the substrate 110 through the flexible circuit board 160.

於本發明之部分實施方式中，顯示面板100更包含保護層180、靜電防護元件190以及導線200。保護層180設置於訊號線150以及輔助訊號線150A上，其厚度大約為1000埃至4000埃，例如大約2000埃或3000埃。靜電防護元件190可以設置於絕緣層170與保護層180之間或保護層180之上。舉例而言，靜電防護元件190可以是二極體、電容或或其組合。導線200設置於保護層180上，且連接第一延伸段154-Z之第二部分P2與靜電防護元件190。 In some embodiments of the present invention, the display panel 100 further includes a protective layer 180, an electrostatic protection element 190, and a lead 200. The protective layer 180 is disposed on the signal line 150 and the auxiliary signal line 150A, and has a thickness of about 1000 Angstroms to 4000 Angstroms, for example, about 2000 Angstroms or 3000 Angstroms. The ESD protection element 190 may be disposed between or over the insulating layer 170 and the protective layer 180. For example, the ESD protection element 190 may be a diode, a capacitor, or a combination thereof. The conductive wire 200 is disposed on the protective layer 180 and connects the second portion P2 of the first extension 154-Z and the electrostatic protection element 190.

如前所述，輔助訊號線150A不覆蓋第一延伸段154-Z之第二部分P2，進而讓出第一延伸段154-Z之第二部分P2以供導線200連接，而使訊號線150透過導線200電性耦接靜電防護元件190。如此一來，導線200與訊號線150之間設置有絕緣層170與保護層180，同時參考第1圖至第3圖，當設置有多條訊號線150以及其導線200時，可以避免橫跨訊號線150 的導線200與訊號線150的交互干擾(crosstalk)。在此，為了有效地避免交互干擾，導線200與訊號線150之間採用雙層(絕緣層170與保護層180)的設計。於其他實施方式中，如若絕緣層170的厚度足夠抵抗上述的交互干擾，可以不必設計保護層180於導線200與訊號線150之間。 As mentioned above, the auxiliary signal line 150A does not cover the second portion P2 of the first extension 154-Z, and then the second portion P2 of the first extension 154-Z is allowed to be connected by the wire 200, so that the signal line 150 The static electricity protection element 190 is electrically coupled through the wire 200. In this way, an insulating layer 170 and a protective layer 180 are provided between the conductive line 200 and the signal line 150, and referring to FIGS. 1 to 3 at the same time, when a plurality of signal lines 150 and the conductive line 200 are provided, crossover can be avoided. A crosstalk between the conductive line 200 of the signal line 150 and the signal line 150. Here, in order to effectively avoid mutual interference, a double-layer design (insulating layer 170 and protective layer 180) is adopted between the conductive line 200 and the signal line 150. In other embodiments, if the thickness of the insulating layer 170 is sufficient to resist the above-mentioned mutual interference, it is not necessary to design the protective layer 180 between the conductive line 200 and the signal line 150.

第4圖為第1圖之顯示面板100的局部P4之上視放大示意圖。多個訊號線150可具體分為訊號線150-1~150-n，多個第一延伸段154可具體分為第一延伸段154-1、154-2等。每一訊號線150-1~150-n之第一延伸段154其中一者(在此即為第一延伸段154-1)具有實質平行於源極扇出線路134的側邊。具體而言，如圖所示，源極扇出線路134包含多個扇出導線134-1~134-n，第一延伸段154-1的至少一側邊與扇出導線134-1的側邊平行。於本發明之多個實施方式中，訊號線150-1~150-n之第一延伸段154-1的最大寬度差異不大。舉例而言，即訊號線150-1之第一延伸段154-1的最大寬度W1為訊號線150-2之第一延伸段154-1的最大寬度W2的1.5至5倍。更甚者，訊號線150-1之第一延伸段154-1的最大寬度W1為訊號線150-2之第一延伸段154-1的最大寬度W2的在1.5至3倍或2至3倍。在此，訊號線150-1較訊號線150-2更靠近源極扇出線路134，舉例而言，訊號線150-1為訊號線150最靠近顯示區DA之一者，訊號線150-2為訊號線150之次靠近顯示區DA之一者。於此，訊號線150-1可以是電源線，例如用以提供接地電位的COM電源線，訊號線150-2可以提供時序訊號，以時序控制閘極驅動器142輸出掃描訊號。於其他實施方式中，訊號線150-1之第一延伸段154-1的最大寬度W1可為訊號線150-3~150-n其中一者之第一延伸段154-1的最大寬度的1.5至5倍。 FIG. 4 is an enlarged schematic top view of a part P4 of the display panel 100 in FIG. 1. The plurality of signal lines 150 may be specifically divided into signal lines 150-1 to 150-n, and the plurality of first extension sections 154 may be specifically divided into first extension sections 154-1, 154-2, and the like. One of the first extensions 154 (here, the first extension 154-1) of each of the signal lines 150-1 to 150-n has a side substantially parallel to the source fan-out line 134. Specifically, as shown in the figure, the source fan-out line 134 includes a plurality of fan-out wires 134-1 to 134-n, at least one side of the first extension 154-1 and a side of the fan-out wire 134-1. The sides are parallel. In various embodiments of the present invention, the maximum widths of the first extensions 154-1 of the signal lines 150-1 to 150-n are not significantly different. For example, the maximum width W1 of the first extension 154-1 of the signal line 150-1 is 1.5 to 5 times the maximum width W2 of the first extension 154-1 of the signal line 150-2. Furthermore, the maximum width W1 of the first extension 154-1 of the signal line 150-1 is 1.5 to 3 times or 2 to 3 times the maximum width W2 of the first extension 154-1 of the signal line 150-2. . Here, the signal line 150-1 is closer to the source fan-out line 134 than the signal line 150-2. For example, the signal line 150-1 is one of the signal lines 150 closest to the display area DA, and the signal line 150-2 It is one of the signal lines 150 next to the display area DA. Here, the signal line 150-1 may be a power line, for example, a COM power line for providing a ground potential, and the signal line 150-2 may provide a timing signal to sequentially control the gate driver 142 to output a scanning signal. In other embodiments, the maximum width W1 of the first extension segment 154-1 of the signal line 150-1 may be 1.5 of the maximum width of the first extension segment 154-1 of one of the signal lines 150-3 to 150-n. To 5 times.

於部分實施方式中，第一延伸段154之至少一者的相對二側邊與源極扇出線路134的側邊平行。如圖所示，源極扇出線路134包含多個扇出導線134-1~134-n，訊號線150-2的第一延伸段154-1的相對二側邊與扇出導線134-1的側邊平行。 In some embodiments, opposite two sides of at least one of the first extension segments 154 are parallel to the sides of the source fan-out line 134. As shown in the figure, the source fan-out circuit 134 includes a plurality of fan-out wires 134-1 to 134-n, the two opposite sides of the first extension 154-1 of the signal line 150-2 and the fan-out wire 134-1. The sides are parallel.

透過上述配置，可以使各個訊號線150-1~150-n的寬度較為平均，避免某些訊號線150-1~150-n的寬度太小，而有電阻過高的問題。 Through the above configuration, the width of each signal line 150-1 ~ 150-n can be made more even, and the problem that the width of some signal lines 150-1 ~ 150-n is too small and the resistance is too high can be avoided.

回到第3圖，於本發明之部分實施方式中，顯示面板100更包含第二基板220、液晶層(未繪示)以及封膠240。第二基板220相對第一基板110設置。液晶層(未繪示)設置於第一基板110與第二基板220之間。封膠240設置於第一基板110與第二基板220之間且環繞液晶層(未繪示)，其中封膠240覆蓋導線200與第二通孔174，以防止灰塵或腐蝕影響其電性。於此，封膠240位於顯示區DA以外的區域，液晶層(未繪示)至少位於顯示區DA以內的區域。於此，封膠240可完全填滿顯示區DA以外的區域，而將液晶層限制於顯示區DA內。當然不應以此限制本發明之範圍，於其他實施方式中，液晶層可以位於顯示區DA以外的區域，即可位於圖中封膠240的區域。 Returning to FIG. 3, in some embodiments of the present invention, the display panel 100 further includes a second substrate 220, a liquid crystal layer (not shown), and a sealant 240. The second substrate 220 is disposed opposite the first substrate 110. A liquid crystal layer (not shown) is disposed between the first substrate 110 and the second substrate 220. The sealant 240 is disposed between the first substrate 110 and the second substrate 220 and surrounds the liquid crystal layer (not shown). The sealant 240 covers the wires 200 and the second through holes 174 to prevent dust or corrosion from affecting its electrical properties. Here, the sealant 240 is located in a region other than the display area DA, and the liquid crystal layer (not shown) is located in at least a region within the display area DA. Here, the sealant 240 can completely fill the area outside the display area DA, and the liquid crystal layer is limited to the display area DA. Of course, the scope of the present invention should not be limited in this way. In other embodiments, the liquid crystal layer may be located in a region other than the display area DA, that is, a region of the sealant 240 in the figure.

於本發明之多個實施方式中，第一基板110例如為一薄膜電晶體基板，而第二基板220為一彩色濾光片基板，遮光層LS設置於第二基板220上，但並不以此為限。於其他實施方式中，第一基板110亦可為彩色濾光片整合電晶體(color filter on array；COA)基板或是黑色矩陣整合電晶體(black matrix on array；BOA)基板。 In various embodiments of the present invention, the first substrate 110 is, for example, a thin-film transistor substrate, and the second substrate 220 is a color filter substrate. The light-shielding layer LS is disposed on the second substrate 220. This is limited. In other embodiments, the first substrate 110 may be a color filter on array (COA) substrate or a black matrix on array (BOA) substrate.

至此，本發明之部分實施方式中，設計訊號線有特殊的轉線機制，而能夠在維持窄邊框的設計下，改善訊號線電阻過大問題。應了解到，本發明之各個圖式中的畫素120、閘極扇出線路144的導線、閘極輸入線路146的導線、源極扇入線路136的導線、源極扇出線路134的導線(例如扇出導線134-1~134-n)、訊號線150的數量或斜率分布等僅為示意，不應用以限制本發明之範圍。 So far, in some embodiments of the present invention, the design of the signal line has a special turning mechanism, which can improve the problem of excessive resistance of the signal line while maintaining a narrow frame design. It should be understood that the pixels 120, the wires of the gate fan-out line 144, the wires of the gate input line 146, the wires of the source fan-in line 136, and the wires of the source fan-out line 134 in the various drawings of the present invention. (For example, fan-out wires 134-1 to 134-n), the number of signal lines 150, or the slope distribution are for illustration only, and should not be used to limit the scope of the present invention.

第5圖為根據本發明之另一實施方式之顯示面板100的訊號線150的上視示意圖。本實施方式與前述第2圖的實施方式相似，差別在於：於本實施方式中，輔助訊號線150A覆蓋訊號線150之第一連接段152、第一延伸段154、第二延伸段156以及第二連接段158，絕緣層170之第二通孔174對應訊號線150之第二連接段158。 FIG. 5 is a schematic top view of a signal line 150 of a display panel 100 according to another embodiment of the present invention. This embodiment is similar to the embodiment shown in FIG. 2 except that in this embodiment, the auxiliary signal line 150A covers the first connection section 152, the first extension section 154, the second extension section 156, and the first extension section 152 of the signal line 150. The two connecting sections 158 and the second through holes 174 of the insulating layer 170 correspond to the second connecting sections 158 of the signal line 150.

於本實施方式中，可不設置連接訊號線150之導線200以及靜電防護元件190(參考第2圖與第3圖)。或者，可以其他適當方式配置靜電防護元件190電性耦接訊號線150。 In this embodiment, the conductive wire 200 and the ESD protection element 190 connected to the signal line 150 may not be provided (refer to FIGS. 2 and 3). Alternatively, the electrostatic protection element 190 may be configured to be electrically coupled to the signal line 150 in other suitable manners.

如此一來，儘管訊號線150的第一延伸段154以及第二延伸段156的寬度較窄，透過輔助訊號線150A的設置可以降低訊號傳遞的電阻，相當於增加訊號傳遞路徑中截面積大小，並避免因為而使電阻過高而容易產生高溫的情況。 In this way, although the width of the first extension 154 and the second extension 156 of the signal line 150 is narrow, the resistance of the signal transmission can be reduced by setting the auxiliary signal line 150A, which is equivalent to increasing the cross-sectional area in the signal transmission path. And avoid the situation that the resistance is too high and easy to produce high temperature.

本實施方式的其他細節大至如第1圖的實施方式所述，在此不再贅述。 The other details of this embodiment are as large as the embodiment shown in FIG. 1, and are not repeated here.
