As shown in FIG. 2 , the display panel has a frame area B and a bending area S located on one side of the frame area B. As shown in FIG. The frame area B surrounds the display area (not shown in FIG. 2 ), and the bending area S is located on a side of the frame area B away from the display area.
显示面板包括：基板11、封装层12、支撑层15和阻隔层16。The display panel includes: a
其中，基板11包括金属走线110和挡墙111。金属走线110位于边框区B，并延伸至弯折区S。挡墙111位于边框区B，与金属走线110叠置。挡墙111用于对封装层12进行限位，以将封装层限制在边框区B范围内，保证封装效果。Wherein, the
具体而言，基板11为发光基板，包括依次叠置的衬底112、TFT阵列层和发光器件层(图中未示出)。基板11还可以包括缓冲层113和填充层114，缓冲层位于衬底112和TFT阵列层之间，弯折区S的缓冲层113上开设有通孔，通孔内填充有填充层114。衬底112的材料可以是聚酰亚胺，缓冲层的材料可以是氮化硅、氧化硅、氧化铝、氧化镁等。TFT阵列层包括多个金属层，至少一个金属层中的金属走线110从边框区B延伸至弯折区S。金属走线110例如可以是扫描信号线、数据信号线、参考电压信号线中的至少一项。金属走线110从显示区延伸至弯折区S，以在弯折区S的远离显示区的一端形成金手指，用于与驱动芯片电连接，用于接收或输出电信号。Specifically, the
封装层12与基板11叠置，并终止于挡墙111的靠近弯折区S的一侧。这种情况下，边框区B的金属走线110可以被封装层12覆盖，弯折区S的金属走线110形成裸露区域。The
支撑层15叠置在弯折区S的金属走线110的远离基板11的一侧。支撑层15用于在弯折区S起支撑作用。支撑层15背离金属走线110的表面为平面。支撑层15的厚度大于或等于8微米，并且小于或等于5微米。例如，支撑层15最厚的区域的厚度可以设置为8微米，最薄的区域的厚度可以设置为5微米。支撑层15固化后的模量大约为1Gpa。支撑层15的材料可以是改性丙烯酸高分子材料，或固化后具有大致相同模量的其它材料。The supporting

如图6所示的显示模组还可以包括绝缘胶带(图中未示出)。绝缘胶带覆盖防静电层18的至少部分区域。绝缘胶带包括露铜区，露铜区与防静电层18接触。后续通过将绝缘胶带中具有露铜区的铜层与终端机壳接触，便可以将防静电层18导出的静电荷释放到终端机壳，进而通过人体导入大地，实现静电释放的效果。The display module shown in FIG. 6 may further include an insulating tape (not shown in the figure). The insulating tape covers at least a partial area of the
本申请实施例还提供了一种显示面板的制备方法。图7为本申请一实施例提供的显示面板的制备方法的流程示意图。如图7所示，制备方法700包括：The embodiment of the present application also provides a method for manufacturing a display panel. FIG. 7 is a schematic flowchart of a method for manufacturing a display panel provided by an embodiment of the present application. As shown in Figure 7, the
步骤S710，在基板上制备封装层，基板包括金属走线和挡墙，金属走线位于边框区，并延伸至弯折区，挡墙位于边框区，与金属走线叠置，封装层从边框区延伸并终止于挡墙的靠近弯折区的一侧。Step S710, preparing an encapsulation layer on the substrate. The substrate includes metal traces and retaining walls. The metal traces are located in the frame area and extend to the bending area. The retaining walls are located in the frame area and overlap the metal traces. The encapsulation layer extends from the frame The zone extends and terminates on the side of the retaining wall near the bend zone.
步骤S720，在弯折区的金属走线上制备支撑层，支撑层与封装层接触。In step S720, a support layer is prepared on the metal wiring in the bending area, and the support layer is in contact with the encapsulation layer.
例如采用喷墨打印方式制备支撑层。具体而言，先在弯折区的金属走线上喷涂支撑材料，待支撑材料流平后，对支撑材料进行固化，得到支撑层。固化方式可以是高温固化或光固化。For example, inkjet printing is used to prepare the supporting layer. Specifically, the support material is first sprayed on the metal traces in the bending area, and after the support material is leveled, the support material is cured to obtain a support layer. The curing method can be high temperature curing or light curing.
在一个实施例中，在步骤S720之前，还包括制备堤坝的步骤。具体而言，将支撑材料调整到第一粘稠度，采用喷墨打印方式在弯折区S远离边框区B的一侧喷涂支撑材料，对支撑材料进行固化，得到堤坝。这种情况下，步骤S720可执行为，将支撑材料调整到第二粘稠度，第二粘稠度小于第一粘稠度。采用喷墨打印方式在挡墙和堤坝之间喷涂支撑材料，待支撑材料流平后，对支撑材料进行固化，得到支撑层。In one embodiment, before step S720, a step of preparing a dam is further included. Specifically, the support material is adjusted to the first viscosity, and the support material is sprayed on the side of the bending area S away from the frame area B by inkjet printing, and the support material is cured to obtain a dam. In this case, step S720 may be performed as adjusting the support material to a second viscosity, and the second viscosity is smaller than the first viscosity. The support material is sprayed between the retaining wall and the embankment by inkjet printing, and after the support material is leveled, the support material is cured to obtain a support layer.
步骤S730，在支撑层上制备阻隔层，得到显示面板。Step S730, preparing a barrier layer on the support layer to obtain a display panel.
例如采用喷墨打印方式制备阻隔层。具体而言，先在支撑层上喷涂阻隔材料，待阻隔材料流平后，对阻隔材料进行固化，得到阻隔层。固化方式可以是高温固化或光固化。For example, the barrier layer is prepared by inkjet printing. Specifically, the barrier material is first sprayed on the support layer, and after the barrier material is leveled, the barrier material is cured to obtain the barrier layer. The curing method can be high temperature curing or light curing.
制备方法700还可以包括：在阻隔层上制备防静电层，防静电层在基板上的正投影覆盖边框区的至少部分封装层。The
例如，首先，采用蒸镀工艺在阻隔层上蒸镀金属层；然后，采用光刻、干刻工艺对金属层进行图形化，得到防静电层。For example, first, a metal layer is evaporated on the barrier layer by using an evaporation process; then, the metal layer is patterned by a photolithography and dry etching process to obtain an antistatic layer.
