Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Referring to fig. 1, an array substrate 100 according to a first embodiment of the invention has a routing area. The routing area includes a support layer 110, a flexible I-shaped strip 120, a metal routing 130, and a routing cover layer 140.
Wherein, the routing area is the area where the metal trace 130 is located. In addition, the array substrate 100 has a display area (i.e., an AA area) and a non-display area (i.e., a non-AA area). The wiring area can be positioned in the display area or the non-display area.
The supporting layer 110 is located at the bottom and can support and protect various elements located above the supporting layer. The material of the support layer 110 is preferably a flexible material capable of supporting.
Wherein the flexible I-shaped strip 120 is formed on the support layer 110. The flexible I-shaped strip 120 may be formed on the support layer 110 by evaporation, etching, or the like.
The flexible I-shaped strip 120 includes a web 121 and first and second wings 122 and 123 respectively located on both sides of the web 121. A first groove 124 far from the support layer 110 and a second groove 125 close to the support layer 110 are formed between the first wing plate 122, the second wing plate 123 and the web 121.
The material of the flexible I-shaped strip 120 is preferably a material that has certain flexibility and is not easily broken.
The metal trace 130 is located in the first groove 124. Preferably, the width of the first groove 124 is greater than the width of the metal trace 130, as shown in fig. 1. In this embodiment, the metal trace 130 is disposed in the middle of the first groove 124. After the arrangement, the two sides of the metal wire 130 are reserved with movable spaces, so that the two sides of the metal wire 130 are prevented from being extruded to cause overlarge stress and fracture in the bending process of the metal wire 130.
Of course, the position and size of the metal trace 130 are not limited thereto. For example, in other embodiments, the metal trace 130 can be adjacent to the first wing 122 or the second wing 123; the width of the metal trace 130 may also be equal to the width of the first groove 124.
The trace covering layer 140 is used for protecting the metal trace 130. The trace covering layer 140 and the flexible I-shaped strip 120 fix the metal trace 130 in the first groove 124.
In this embodiment, the second groove 125 is filled with a flexible filling body 150 for supporting the web 121. When the array substrate 100 is bent, the web 121 of the flexible i-shaped strip 120 is subjected to stress bending. At this time, the flexible filling body 150 can support the web 121, so as to slow down the extrusion of the underlying film layer on the metal traces 130 located in the first groove 124.
Preferably, the flexible filling member 140 is made of acrylic, epoxy resin or silicon-based polymer. These kinds of flexible fillers 140 can support the web 121 well.
