Description

Display panel

Technical Field

The present invention relates to a display panel, and more particularly, to a display panel.

Background

The line defect (line defect) on the display panel is repaired by repairing the line (repair line) on the design of the display panel. As the panel size is increased, how to increase the repair line success rate of the repair line has become an urgent issue to be solved.

Disclosure of Invention

The invention provides a display panel with better quality.

The display panel comprises a substrate, a plurality of pixel units, frame glue and a first repair line. The substrate is provided with a display area and a peripheral line area surrounding the display area. The peripheral line zone comprises a first peripheral line zone, a second peripheral line zone connected with the first peripheral line zone and a third peripheral line zone opposite to the first peripheral line zone. The plurality of pixel units are positioned on the display area of the substrate. The frame glue is positioned on the peripheral line area of the substrate. The first repair line is located on the substrate and extends from the first peripheral line region to the third peripheral line region along the second peripheral line region. The first repairing line comprises a first repairing line segment and at least one second repairing line segment. The first repairing line segment is located in the second peripheral line region and the third peripheral line region and located on the outer side of the frame glue. The second repairing line segment is electrically connected to the first repairing line segment and located in the third peripheral line region. Part of the second repairing line segment extends from the outer side of the frame glue to the inner side of the frame glue. The second repairing line segment comprises a first wire, a second wire and a first through hole. The first through hole is positioned on the inner side of the frame glue, and the first wire and the second wire are electrically connected through the first through hole.

The display panel comprises a substrate, a plurality of pixel units, frame glue, a first repair line, a first conductive layer, an insulating layer, a second conductive layer and a through hole. The substrate is provided with a display area, a peripheral line area surrounding the display area and an auxiliary area positioned between the peripheral line area and the display area. The plurality of pixel units are positioned on the display area of the substrate. The frame glue is positioned on the peripheral line area of the substrate. The first repair line is located on the substrate and extends from the first peripheral line region to the third peripheral line region along the second peripheral line region. The first conductive layer is located on the substrate. The insulating layer is positioned on the substrate and covers the first conducting layer. The second conductive layer is located on the insulating layer. The through hole is positioned on the first conductive layer. The through hole penetrates through the insulating layer and the second conductive layer. The connecting wire covers the side wall of the second conductive layer and the upper surface of the first conductive layer to electrically connect the first conductive layer and the second conductive layer.

Based on the above, since part of the first repair line is located outside the sealant, the resistance-capacitance load (RC loading) of the first repair line can be reduced, and the line repair success rate of the repair line segment can be improved. In addition, part of the first repair line can comprise the first routing and the second routing, so that the resistance of the first repair line can be reduced. In addition, the first through hole for electrically connecting the first wire and the second wire is positioned at the inner side of the frame glue, so that the first repairing wire can be damaged. Therefore, the quality of the display panel can be improved.

In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description

In the drawings, the thickness of various elements and the like are exaggerated for clarity. Like reference numerals refer to like elements throughout the specification. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" or "overlapping" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physically and/or electrically connected.

It will be understood that, although the terms "first," "second," "third," "fourth," "fifth," "sixth," "seventh," "eighth," or "one," "another," "yet" etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a "first element," "first component," "first region," "first orientation," or "first portion" discussed below could be termed a "second element," "second component," "second region," "second orientation," or "second portion" without departing from the teachings herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms, including "at least one", unless the content clearly indicates otherwise. "or" means "and/or". As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, relative terms, such as "lower" or "bottom" and "upper" or "top," may be used herein to describe one element's relationship to another element, as illustrated. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. Thus, the exemplary term "lower" can include both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "below" or "beneath" can encompass both an orientation of above and below.

As used herein, "about", "substantially", or "approximately" includes the stated value and the average value within an acceptable range of deviation of the specified value as determined by one of ordinary skill in the art, taking into account the measurement in question and the specified amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" may mean within one or more standard deviations of the stated value, or within ± 30%, ± 20%, ± 10%, ± 5%.

Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Exemplary embodiments are described herein with reference to cross-sectional views that are schematic illustrations of idealized embodiments. Thus, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, the embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region shown or described as flat may generally have rough and/or nonlinear features. Further, the acute angles shown may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the claims.

Fig. 1B is a schematic top view of a display panel in a second state according to an embodiment of the invention. Fig. 1C is a schematic top view of a display panel according to an embodiment of the invention. For example, fig. 1A may be a top view of a display panel in a normal (normal) state according to an embodiment of the present invention, fig. 1B may be a top view of a display panel in an unrepaired state with a line defect according to an embodiment of the present invention, and fig. 1C may be a top view of a display panel in a repaired line defect state according to an embodiment of the present invention. For clarity, a part of the film layer (film layer) or the member is omitted in fig. 1A to 1C. For example, the liquid crystal is omitted from fig. 1A to 1C.

Referring to fig. 1A to 1C, the display panel 100 includes a substrate 110, a plurality of pixel units PU1, PU2, PU3, sealant 170, and repair lines (e.g., at least one of the first repair line 120, the second repair line 220, and the third repair line 320). The substrate 110 has a display region 111 and a peripheral region 112. The peripheral edge region 112 surrounds the display region 111. The peripheral line zone 112 includes a first peripheral line zone 112a, a second peripheral line zone 112b, a third peripheral line zone 112c and a fourth peripheral line zone 112 d. The third peripheral line 112c is opposite to the first peripheral line 112a, and the second peripheral line 112b connects the first peripheral line 112a and the third peripheral line 112 c. The fourth peripheral line region 112d is opposite to the second peripheral line region 112b, and the fourth peripheral line region 112d connects the first peripheral line region 112a and the third peripheral line region 112 c. The pixel units PU1, PU2, PU3 are located on the display region 111 of the substrate 110, the pixel units PU1, PU2, PU3 can be formed by a general semiconductor process, and the design or configuration of the pixel units PU1, PU2, PU3 can be adjusted according to the requirements, which is not limited by the invention. The sealant 170 is disposed on the peripheral region 112 of the substrate 110. That is, the sealant 170 may surround the display region 111 of the substrate 110, and the display region 111 is substantially located on the inner side 171 of the sealant 170. In other words, the outer side 172 of the sealant 170 is a side closer to the edge 119 of the substrate 110, and the inner side 171 of the sealant 170 is a side closer to the display region 111 (or the pixel units PU1, PU2, PU3) of the substrate 110. The repair line (e.g., at least one of the first repair line 120, the second repair line 220 and the third repair line 320) is disposed on the substrate 110, and extends from the first peripheral region 112a to the third peripheral region 112c along the second peripheral region 112b or the fourth peripheral region 112 d. For example, the first repair line 120 is located on the substrate 110, and the first repair line 120 extends from the first peripheral region 112a to the third peripheral region 112c along the second peripheral region 112 b.

In the present embodiment, the first repair line 120 is electrically connected to a driving element 105 at the first peripheral region. The driving element 105 is, for example, a driver IC (driver IC). The driving element 105 may be disposed on the substrate 110 or on another Circuit board (e.g., a Flexible Printed Circuit (FPC)), which is not limited in the present invention.

In the present embodiment, if the display panel 100 is in a normal state (as shown in fig. 1A, where "normal" indicates that a specific driving device 105 can drive a specific pixel unit through a specific signal line), the pixel units PU1, PU2, PU3 can be electrically connected to the corresponding driving device 105 through the

corresponding signal lines

421, 422, 423. If the display panel 100 has a line defect and is not repaired (as shown in FIG. 1B), at least one of the pixel units PU1, PU2, PU3 may not be electrically connected to the corresponding driving device 105 through the

corresponding signal lines

421, 422, 423. In the embodiment shown in fig. 1B, the line defect is, for example, a disconnection of the signal line 421, but the invention is not limited thereto. In addition, in the embodiment shown in fig. 1B, a line defect of the signal line 421 is exemplarily shown, but the present invention is not limited thereto. If the display panel 100 is in a repaired line defect state (as shown in fig. 1C), the pixel units PU1, PU2, PU3 can be electrically connected to the corresponding driving devices 105 through the corresponding repair lines (e.g., the first repair line 120, the second repair line 220, or the third repair line 320). In the embodiment shown in fig. 1C, the line defect of the signal line 421 has been repaired for exemplary illustration, but the present invention is not limited thereto. In addition, the conduction or line defect of the conductive line (e.g., the signal line 421, the signal line 422, the signal line 423, the first repair line 120, the second repair line 220, or the third repair line 320) can be determined by the conduction or the disconnection of the conductive line, and is schematically illustrated in fig. 1A to 1C only by way of a structure. Thus, the display panel 100 has better display quality.

The repairing manner of the first repairing line 120 to the pixel unit PU1 is as follows. When the pixel unit PU1 of the display panel 100 is in a normal state (as shown in FIG. 1B), the pixel unit PU1 can be electrically connected to the corresponding driving device 105 through the corresponding signal line 421. In the circuit of the display panel 100, the pixel unit PU1 cannot be electrically connected to the corresponding driving device 105 through the corresponding original circuit (e.g., the signal line 421) in the state that the original circuit (e.g., the signal line 421) connected to the pixel unit PU1 has a line defect (e.g., as shown in FIG. 1B). In the circuit of the display panel 100, after the circuit connected to the pixel unit PU1 is repaired (as shown in fig. 1C), the pixel unit PU1 may not be electrically connected to the corresponding driving device 105 through the signal line 421, and the pixel unit PU1 may be electrically connected to the corresponding driving device 105 through the first repair line 120. For example, the different conductive layers (e.g., the first conductive layer M1 and the second conductive layer M2, shown in FIGS. 2B and 2C or FIGS. 3B and 3C) in the Repair area (e.g., the Repair area 114a shown in FIG. 2A or the Repair area 114 a' shown in FIG. 3A) and the Repair area 114B (shown in FIG. 8A) (e.g., the first conductive layer M1 and the second conductive layer M2, shown in FIGS. 8B-8C) may be electrically connected to each other by Laser Repair Technology (LRT), so that the pixel unit (e.g., the pixel unit PU1) may be electrically connected to the corresponding driving element (e.g., the driving element 105) through the corresponding Repair line (e.g., the first line 120) and the signal line 420 (shown in FIG. 8A). The repairing manner of the second repairing line 220 to the pixel unit PU2 and/or the repairing manner of the third repairing line 320 to the pixel unit PU3 may be the same or similar to the repairing manner of the first repairing line 120 to the pixel unit PU1, and thus are not repeated herein.

The first repair line 120 may include a first repair line segment 130 and second

repair line segments

140 and 140 ', and the first repair line segment 130 is electrically connected to the second

repair line segments

140 and 140'. The first repairing line segment 130 is located in the second peripheral line region 112b and the third peripheral line region 112c of the substrate 110, and the first repairing line segment 130 is located on the outer side 172 of the sealant 170.

Generally, the relative permittivity (relative permittivity) of the sealant 170 is greater than the relative permittivity of the liquid crystal, and the relative permittivity of the liquid crystal is greater than the relative permittivity of air. Therefore, the resistance-capacitance loading (RC loading) of the repair line (e.g., the first repair line 120, the second repair line 220, or the third repair line 320) can be reduced by the repair line segment (e.g., the first repair line segment 130) located on the outer side 172 of the sealant 170, so as to improve the line repair success rate of the repair line (e.g., the first repair line 120, the second repair line 220, or the third repair line 320).

The second repairing

line segments

140 and 140 'are located in the third peripheral edge region 112c of the substrate 110, and a portion of the second repairing

line segments

140 and 140' extend from the outer side 172 of the sealant 170 to the inner side 171 of the sealant 170.

The layout of the portion of the third perimeter line 112c (layout) is described in detail below.

Referring to fig. 1A to 4C, fig. 2A to 2C may be enlarged schematic views of a region R1 in fig. 1A to 1C, fig. 3A to 3C may be enlarged schematic views of a region R2 in fig. 1A to 1C, and fig. 4A to 4C may be enlarged schematic views of a region R3 in fig. 1A to 1C. For clarity, some of the layers or members are omitted from fig. 2A to 4C. Fig. 2B may be a portion of the first conductive layer M1 of the region R1 in the display panel 100, fig. 2C may be a portion of the second conductive layer M2 of the region R1 in the display panel 100, and fig. 2A may be at least a portion of the first conductive layer M1, a portion of the second conductive layer M2, and a portion of the sealant 170 of the region R1 in the display panel 100. Fig. 3B may be a portion of the first conductive layer M1 of the region R2 in the display panel 100, fig. 3C may be a portion of the second conductive layer M2 of the region R2 in the display panel 100, and fig. 3A may be at least a portion of the first conductive layer M1, a portion of the second conductive layer M2, and a portion of the sealant 170 of the region R2 in the display panel 100. Fig. 4B may be a portion of the first conductive layer M1 of the region R3 in the display panel 100, fig. 4C may be a portion of the second conductive layer M2 of the region R3 in the display panel 100, and fig. 4A may be at least a portion of the first conductive layer M1, a portion of the second conductive layer M2, and a portion of the sealant 170 of the region R3 in the display panel 100.

Please refer to fig. 1A to fig. 2C. In this embodiment, the display panel 100 may include a second repair line 220. The second repair line 220 is located on the substrate 110, and the second repair line 220 extends from the first peripheral region 112a to the third peripheral region 112c along the second peripheral region 112 b. The second repair line 220 is electrically connected to the driving element 105 at the first peripheral region 112 a.

In the present embodiment, the second repair line 220 may include a third repair line segment 230 and a fourth repair line segment 240, and the third repair line segment 230 is electrically connected to the fourth repair line segment 240. The third repairing line segment 230 is located at the second peripheral region 112b and the third peripheral region 112c of the substrate 110, and the third repairing line segment 230 is located at the outer side 172 of the sealant 170. The fourth repairing line segment 240 is located in the third peripheral region 112c of the substrate 110, and the fourth repairing line segment 240 extends from the outer side 172 of the sealant 170 to the inner side 171 of the sealant 170. The third repair line segment 230 is located between the first repair line segment 130 and the edge 119 of the substrate 110, and the width 230w of the third repair line segment 230 is greater than the width 130w of the first repair line segment 130. In this way, the resistance of the first repair line segment 130 of the first repair line 120 can be the same as or similar to the resistance of the third repair line segment 230 of the second repair line 220.

In the embodiment, the width 240w of the fourth repairing line segment 240 in the parallel sealant 170 is smaller than the width 140w of the second repairing line segment 140 in the parallel sealant 170. In this way, the resistance of the second repair line segment 140 of the first repair line 120 can be the same as or similar to the resistance of the fourth repair line segment 240 of the second repair line 220.

Referring to fig. 2A to fig. 3C, in the present embodiment, the second repair line segment 140 may include a first trace 141, a second trace 142 and a first through hole TH1, and the second repair line segment 140 'may include a first trace 141', a second trace 142 'and a first through hole TH 1'. The first through holes TH1 and TH 1' are located on the inner side 171 of the sealant 170. The first trace 141 and the second trace 142 are electrically connected through the first through hole TH 1. The first trace 141 ' and the second trace 142 ' are electrically connected through the first through hole TH1 '.

In this embodiment, the first routing 141, 141 'may be a portion of the first conductive layer M1, and the second routing 142, 142' may be a portion of the second conductive layer M2. The first conductive layer M1 or the second conductive layer M2 may be a single-layer or multi-layer structure, and if the conductive layer is a multi-layer structure, the multi-layer structure may not have an insulating material therebetween, and the materials of the multi-layer structure may be the same, similar or different. The first wires 141, 141 ' and the second wires 142, 142 ' can reduce the resistance of the second repair line segments 140, 141 ', and the resistance-capacitance load of the first repair line 120 can be reduced.

In this embodiment, the first repairing line segment 130 may include a third trace 131 and a fourth trace 132. The third trace 131 of the first repairing line segment 130 is connected to the first traces 141, 141 'of the second repairing line segments 140, 141'. The fourth trace 132 of the first repairing line segment 130 is connected to the second traces 142, 142 'of the second repairing

line segments

The foregoing description of the embodiments and the drawings show embodiments that may be included in the display panel of the present invention. In other words, the foregoing embodiments can be combined in a single display panel. Alternatively, the number and the configuration of the repair lines can be changed or adjusted in a single display panel according to design requirements. For example, in a single display panel, only one first repair line 120 may be included; only one second repair line 220 may be included; only one third repair line 320 may be included; one or more first repair lines 120, one or more second repair lines 220, and one or more third repair lines 320 may be included. The form of the through holes in the display panel can be changed or adjusted according to the design requirement. In addition, the form of the electrostatic protection element in the display panel can be changed or adjusted according to the design requirement.

In summary, in the display panel of the invention, since part of the first repair line is located outside the sealant, the resistance-capacitance load (RC loading) of the first repair line can be reduced, and the line repair success rate of the repair line segment can be improved. In addition, part of the first repair line can comprise the first routing and the second routing, so that the resistance of the first repair line can be reduced. In addition, the first through hole for electrically connecting the first wire and the second wire is positioned at the inner side of the frame glue, so that the first repairing wire can be damaged. Therefore, the quality of the display panel can be improved.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
