Description
本发明涉及显示领域,尤其是涉及一种显示面板及其制备方法。
现阶段显示面板产品的芯片封装技术中存在三种结构设计:COG(Chip
on Glass)、COP(Chip
on Panel)和COF(Chip
on Film)。因为有机发光二极管(Organic Light-Emitting Diode,
OLED)相较于液晶显示器(Liquid Crystal Display ,LCD)具有柔性、自发光、面板厚度小、反映时间短等明显的优势,逐渐引起重视,并被普遍认为是下一代主流显示器的应用面板。
在OLED技术中,Panel芯片封装主要使用COP、COF两种结构设计。如图1和图2为面板的COP以及COF封装设计示意图。在COP这种设计结构中,面板下方设计制作了IC
Bonding区域以及FPC Bonding区域。在COF这种设计结构中,面板下方设计制作了COF
Bonding区域。在后段制程中,为增大屏占比,减小边框的尺寸会将面板下方的COF区、IC区、FPC区以及其他的一些线路全部弯折到面板后方。现阶段,模组段LLO(激光剥离技术)制程将面板与玻璃基板剥离开后,会在面板下方贴合支撑层,用以对柔性面板起到一定的保护作用。激光剥离范围为整个面板。在弯折制程时,由于制程中面板承受压力较大,弯折区域下方模组制程段贴合的IC、FPC、COF等端子很容易发生损伤,支撑层一般不能承受过多的压力。
因此,有必要提出一种新的显示面板,提高绑定区的安全性,解决了现有技术中显示面板绑定区受损伤等问题。
本发明的目的在于,提供一种显示面板及其制备方法,在所述绑定区将现有技术中的支撑层由玻璃基板代替,所述玻璃基板相较于支撑层的硬性较大,可以减少激光剥离后至成品运输过程中外力对下方绑定区域端子的损伤。
本发明提供一种显示面板,包括显示区、弯折区以及绑定区;所述弯折区连接所述绑定区与显示区,所述弯折区和所述绑定区位于所述显示区下方,所述绑定区借助所述弯折区通过至少一玻璃基板贴附所述显示区。
进一步地,所述绑定区包括:第一基层,设于所述玻璃基板远离所述显示区的一侧;PAD区,设于所述第一基层远离所述玻璃基板的一侧;绑定元件,设于所述PAD区远离所述第一基层的一侧。
进一步地,所述绑定元件包括集成电路,设于所述PAD区远离所述第一基层的一侧;柔性电路板,设于所述PAD区远离所述第一基层的一侧;所述集成电路与所述柔性电路板同层设置并绑定于所述绑定区。
进一步地,所述绑定元件包括:覆晶薄膜,设于所述PAD区远离所述第一基层的一侧;柔性电路板,设于所述覆晶薄膜远离所述PAD区的一侧;所述柔性电路板通过所述覆晶薄膜绑定于所述绑定区。
进一步地,所述显示区包括:中框;支撑层,设于所述中框远离所述玻璃基板的一侧;第二基层,设于所述支撑层远离所述中框的一侧;阵列基板,设于所述第二基层远离所述支撑层的一侧;有机发光层,设于所述阵列基板远离所述第二基层的一侧;触控屏,设于所述有机发光层远离所述有机发光层远离所述阵列基板的一侧;嵌入式偏光片,设于所述触控屏远离所述有机发光层一侧;其中,所述玻璃基板贴附于所述中框上。
进一步地,所述弯折区包括:第三基层以及有机层;所述有机层设于所述第三基层上。
进一步地,所述第一基层、所述第二基层以及所述第三基层同层制备;所述第三基层连接所述第一基层与所述第二基层。
进一步地,所述阵列基板、所述有机层以及所述PAD区同层制备;所述有机层连接所述阵列基板与所述PAD区。
进一步地,所述第一基层、所述第二基层以及所述第三基层的材料为聚酰亚胺。
本发明还提供一种显示面板的制备方法,包括:提供一玻璃基板、支撑层以及中框;所述玻璃基板包括显示区、弯折区以及绑定区,所述弯折区连接所述显示区所述绑定区;依次在所述显示区的玻璃基板上形成第二基层以及阵列基板;依次在所述弯折区的玻璃基板上形成第三基层以及有机层;依次在所述绑定区的玻璃基板上形成第一基层以及PAD区;依次在所述阵列基板上形成有机发光层、触控屏以及嵌入式偏光片;激光剥离所述显示区以及弯折区的玻璃基板;依次贴合所述支撑层与所述中框于所述第一基层远离所述阵列基板的一侧;将所述弯折区弯折,使得所述绑定区的玻璃基板贴合至所述显示区。
本发明提供一种显示面板及其制备方法,在所述绑定区,将现有技术中的支撑层由玻璃基板代替,所述玻璃基板相较于支撑层的硬性较大,可以减少激光剥离后至成品运输过程中外力对下方绑定区域端子的损伤。在显示区与弯折区进行激光剥离的时候,将绑定区的玻璃基板预留,这样省去现有技术贴合所述绑定区支撑层的步骤,使得支撑层贴合由两道简化为一道,简化了工艺流程。

S4、依次在所述弯折区的玻璃基板上形成第三基层121以及有机层122;所述第三基层121的材料为聚酰亚胺。
S5、依次在所述阵列基板104上形成有机发光层105、触控屏106以及嵌入式偏光片107;
S6、激光剥离所述显示区以及弯折区的玻璃基板131。
S7、依次贴合所述支撑层102与所述中框101于所述第二基层103远离所述阵列基板104的一侧;
S8、将所述第三基层121以及所述有机层122弯折,使得所述绑定区的玻璃基板131贴合至所述中框101上。
本发明提供一种显示面板制备方法,在所述绑定区130,将由玻璃基板131代替现有技术中的支撑层,而玻璃基板原本即是制作显示面板中存在的,一般面板底层具有一层玻璃基板,在显示区110与弯折区120进行激光剥离的时候,将绑定区130的玻璃基板131预留,这样省去现有技术贴合所述绑定区130支撑层102的步骤,使得支撑层102贴合由两道简化为一道,简化了工艺流程。
如图5所示,本发明提供另一是实施例的显示面板100,其不同之处在于,所述绑定区130为COF封装结构。
所述绑定元件137包括:覆晶薄膜136以及柔性电路板135。
所述覆晶薄膜136设于所述PAD区133远离所述第一基层132的一侧;所述柔性电路板135设于所述覆晶薄膜136远离所述PAD区133的一侧;所述柔性电路板135通过所述覆晶薄膜136绑定与所述PAD区133。
以上对本发明实施例提供的显影方法以及金属层的图形化处理方法进行了详细介绍,本文中应用了具体个例对本发明的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本发明。同时,对于本领域的技术人员,依据本发明的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本发明的限制。
