步骤102,去除所述柔性薄膜基板下表面的玻璃基板。
例如,去除该柔性薄膜基板12下表面121的玻璃基板11后,得到如图5中所示的结构。
在一些实施例中,可以通过激光切割的方式切除所述柔性薄膜基板下表面的玻璃基板。
例如,可以通过激光剥离工艺切除该柔性薄膜基板12下表面121的玻璃基板11。
步骤103,在所述柔性薄膜基板的下表面形成覆盖所述柔性薄膜基板下表面的塑胶层。
例如,如图6及图7所示,在该柔性薄膜基板12的下表面121形成覆盖该柔性薄膜基板12下表面121的塑胶层15。其中,该塑胶层15严密贴附于的柔性薄膜基板12下表面121,可以有效避免塑胶层15贴附于柔性薄膜基板12时可能造成的贴附气泡。
在一些实施例中,该塑胶层15包括聚酯薄膜层151以及与该聚酯薄膜层151层叠设置的挡板层152,该塑胶层15通过该挡板层152结合在该柔性薄膜基板12的下表面121。其中,聚酯薄膜层151可以由PET膜(耐高温聚酯薄膜)组成,挡板层152可以由塑胶材质的挡板(back plate)组成。
例如,如图6所示,该塑胶层15可以通过一滚轮16滚动按压的方式结合在该柔性薄膜基板12的下表面121,以得到图7所示的结构。

例如,还可以通过二氧化碳激光器(CO2 Laser)在与该接线区域14正对的位置切除部分该塑胶层15,以形成贯穿该塑胶层15的凹槽17。
在一些实施例中,在形成该凹槽17后,可以将该柔性薄膜基板12上表面122的接线区域14沿该凹槽17弯折。
例如,在该柔性薄膜基板12的下表面121形成覆盖该柔性薄膜基板12下表面121的塑胶层15之后,再依据客户对产品外型的需求,利用紫外激光器将产品的外型切割出来,因挡板层152完整贴附于柔性薄膜基板12下表面121,没有BP段差设计,故在待切除的位置处不会有灰尘残留现象产生,不会造成产品上污染,减少不良品发生,有效提高产品良率;再使用二氧化碳激光器将作为弯折区域的对应的部分聚酯薄膜层151及挡板层152给切除以形成凹槽17,以使得该柔性薄膜基板12上表面122的接线区域14可以沿该凹槽17进行弯折。
在一些实施例中,如图10所示,该挡板层152正对该接线区域14的位置上形成有缺口1521。可以通过去除正对该缺口1521位置处的聚酯薄膜层151,以形成该凹槽17,以得到如图9所示的结构。
例如,可以通过激光切割的方式去除正对该缺口1521位置处的聚酯薄膜层151,以形成贯穿该塑胶层15的凹槽17,最终得到如图9所示的结构。
在一些实施例中,在形成该凹槽17后,可以进一步清理该凹槽17内因去除该聚酯薄膜层所造成的残留物。
例如,在该柔性薄膜基板12的下表面121形成覆盖该柔性薄膜基板12下表面121的塑胶层15之后,再依据客户对产品外型的需求,利用紫外激光器将产品的外型切割出来,因产品设计需要,挡板层152设有缺口1521,存在BP段差设计,故在BP段差处在制程过程中可能有灰尘残留现象产生,因此在使用二氧化碳激光器将缺口1521对应的部分聚酯薄膜层151给切除以形成凹槽17之后,可以进一步清理该凹槽17内因去除该聚酯薄膜层151而可能造成的残留物,以降低产品上的污染,提升产品良率。
