在一种实施例中,栅驱动电路设置在位于显示区101左右两侧中的其中一侧的区域内。栅驱动电路可以是设置在位于显示区101左侧的区域103内,也可以是设置在位于显示区101右侧的区域104内;设置有栅驱动电路的区域,通过局部弯曲后贴合于支撑板20的另一面。

在一种实施例中,支撑板20用于支撑整个显示面板,其材料为玻璃、聚酰亚胺、聚对苯二甲酸乙二醇酯或聚合氯化铝中的一种,如支撑板为玻璃基板,需对玻璃基板进行去毛刺处理,以防止支撑板的下表面或是侧边存在毛刺,柔性驱动电路基板在弯曲以及贴合的过程中,受到刮伤了,从而影响了整个显示面板的品质。
在一种实施例中,支撑板20的尺寸比显示面板显示区101的尺寸略小。这是由于,弯曲部位的柔性驱动电路基板存在一定的厚度,越靠近弯曲内侧的膜层,与支撑板之间的距离越近,越靠近弯曲外侧的膜层,与支撑板之间的距离越远,即位于弯曲内侧的膜层结构的弯曲尺寸要小于位于弯曲外侧的膜层结构的弯曲尺寸,因此需要将支撑板20的尺寸设置的比显示区101的尺寸略小,以便给位于弯曲内侧的膜层留出弯曲位置。在不影响显示面板显示区101膜层结构的基础上,可以尽可能的减小支撑板20的尺寸,以保证柔性驱动电路基板弯曲后,在正面视角内仅保有显示区101,另外需保证支撑板20的尺寸不可过小,以免影响支撑板20的支撑效果,具体尺寸设置可以根据具体需要进行设计,在此不做限定。
在一种实施例中,柔性驱动电路基板200包括柔性衬底210和薄膜晶体管层220,像素驱动电路由薄膜晶体管层220内的薄膜晶体管构成,薄膜晶体管包括源极、漏极、栅极、以及图案化的有源半导体。柔性衬底210的材料为聚酰亚胺、聚对苯二甲酸乙二醇酯、聚丙烯树脂或亚克力树脂等材料中的任意一种,也可以为其他适用于制备柔性基板的可弯折材料,在此不做限制。
在一种实施例中,数据驱动电路走线与薄膜晶体管的源漏极同层设置,数据驱动电路走线与薄膜晶体管内的源极或漏极连接。栅驱动电路走线可以与薄膜晶体管的源漏极同层设置,也可以与薄膜晶体管的栅极同层设置,栅极驱动电路走线与薄膜晶体管内的栅极连接。
在一种实施例中,显示面板还包括数据驱动芯片和栅驱动芯片(未画出),数据驱动芯片绑定于区域102内,数据驱动芯片与数据驱动电路连接,从而向薄膜晶体管的源极或漏极输入数据信号;栅驱动芯片可以绑定于区域103、区域104内,也可以绑定于区域102内,栅驱动芯片与栅驱动电路连接,从而向薄膜晶体管的栅极输入扫描信号。
驱动芯片的封装包括COG方式、COF方式和COP方式,COG为传统的封装方法,驱动芯片直接绑定在显示面板的玻璃表面进行封装,在全面屏趋势以前,基本上所有的手机都采用的是COG封装工艺,芯片被直接绑定在玻璃表面,这种封装可以大大减小整个模块的体积,并且具有良品率高、成本低且易于大批量生产的直接优势;COF封装工艺是将屏幕芯片与部分排线固定于柔性线路板上的晶粒软膜构装,并且运用了软质附加电路板(FPC)作封装芯片载体,将芯片与软性基板电路接合的封装技术,柔性电路板可进行弯折,使之得以叠到屏幕的后方从而缩减了屏幕的芯片和部分排线区域;COP是将显示面板的下侧部分,连带芯片与全部排线区域一起弯折到显示面板的背面,从而达到显示屏上、下、左、右边框同宽的封装方式。
无论是COG芯片封装方式,COF芯片封装方式,还是COP芯片封装方式,本申请实施例提供显示面板,均可以实现将显示区侧边,设置有数据驱动电路、栅驱动电路、静电释放电路的区域弯曲,后置于显示面板的背光侧,使得显示面板的出光面只保有可显示画面的显示区,极大的提高了整个显示面板的屏占比,缓解了现有显示面板无法全面显示的问题。

在一种实施例中,如图8所示,本申请提供一种显示面板的制备方法,其包括:
S1、制备显示面板的各膜层结构。
具体为在玻璃基板上柔性驱动电路基板;当显示面板为OLED显示面板时,还包括在柔性驱动电路基板上依次制备像素电极层、像素定义层、发光材料层、公共电极层、以及封装层;当显示面板为LCD显示面板时,还包括在柔性驱动电路基板上制备像素电极层、平坦化层和第一配向膜,制备彩膜基板,将彩膜基板和阵列基板对盒,在阵列基板和彩膜基板之间填充液晶;最后将显示面板进行封装处理。
S2、在柔性驱动电路基板的对应区域内绑定驱动芯片。
具体步骤为:利用各向异性导电胶将驱动芯片与柔性驱动电路基板的对应区域进行绑定。
当显示面板为LCD显示面板时,在进行S3步骤之前,还需要在显示面板的阵列基板侧和彩膜基板侧分别贴合第一偏光片和第二偏光片。
S3、在显示面板的背光面制备支撑板。
在一种实施例中,制备支撑膜的具体步骤为:利用激光剥离技术将位于面板显示区外的玻璃基板进行剥离,留下的玻璃基板即为支撑板。该支撑板需要进一步进行去毛刺处理。
在另一种实施例中,制备支撑膜的具体步骤为:利用激光剥离技术将整面玻璃基板进行剥离,在面板显示区内、显示面板的背光侧贴合支撑板,该支撑板可以是玻璃基板,也可以是聚酰亚胺、聚对苯二甲酸乙二醇酯或聚合氯化铝等材料制备而成的聚合物基板。
S4、将柔性驱动电路基板显示区外侧的部分,沿支撑板的边缘向显示面板的背光侧弯曲,并与支撑板贴合绑定。
本申请实施例提供了一种显示面板的制备方法,通过将显示面板内的阵列基板设置为柔性,并将显示面板不显示画面的部分绑定于显示面板的背光侧,使得显示面板的出光面只保有可显示画面的部分,从而实现了极高屏占比的全面屏,解决了现有显示面板无法全面显示的问题。
且在本申请实施例提供的制备方法中,在S1各膜层结构的制备中,可以仅考虑采用技术手段制备性能更优良的显示面板,在后续制程中再改进面板的屏占比,这样极大地提高了显示面板的品质及驱动芯片的绑定良率。
在一种实施例中,本申请提供一种显示装置,该显示装置包括显示面板,该显示面板包括:
支撑板;
阵列基板,包括柔性驱动电路基板,柔性驱动电路基板内设置有位于显示区内的像素驱动电路,位于显示区左右两侧中的至少一侧的区域内的栅驱动电路,以及位于显示区下侧的区域内的数据驱动电路;柔性驱动电路基板的背光面,在显示区内与支撑板贴合;柔性驱动电路基板设置有栅驱动电路和数据驱动电路的区域,通过局部弯曲后贴合于支撑板的另一面。

在另一种实施例中,栅驱动电路设置在位于显示区左右两侧的区域内,静电释放电路设置在位于显示区上侧的区域内;柔性驱动电路基板设置有数据驱动电路、栅驱动电路、静电释放电路的区域,通过局部弯曲后贴合于支撑板的另一面。
在一种实施例中,支撑板的材料为玻璃、聚酰亚胺、聚对苯二甲酸乙二醇酯或聚合氯化铝中的一种。
在一种实施例中,支撑板的尺寸小于显示面板显示区的尺寸。
在一种实施例中,柔性驱动电路基板包括柔性衬底和薄膜晶体管层,像素驱动电路由薄膜晶体管层内的薄膜晶体管构成。
根据上述实施例可知:
本申请提供一种阵列基板、显示面板及显示装置,其阵列基板包括基板和柔性驱动电路基板;其显示面板包括支撑板和阵列基板,阵列基板包括柔性驱动电路基板,柔性驱动电路基板的背光面,在显示区内与支撑板贴合,柔性驱动电路基板设置有栅驱动电路和数据驱动电路的区域,局部弯曲后贴合于支撑板的另一面;这样就使得显示面板的出光面只保有可显示画面的显示区,极大的提高了整个显示面板的屏占比,缓解了现有显示面板无法全面显示的问题。
综上所述,虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
