显示面板及其制作方法 技术领域
本申请涉及显示技术领域,尤其涉及一种显示面板及其制作方法。
背景技术
随着人们生活水平的提高和显示技术的发展,大尺寸液晶电视愈来愈受到消费者的喜爱,同时高分辨率、高对比度、高刷新速率、超窄边框等也成为各电视厂商所追求的亮点和卖点,特别是目前大尺寸液晶面板市场已经全面由4K 60HZ向8K 120HZ转变,要在极高分辨率、高刷新频率情况下,又要保持窄边框的特色,对TFT LCD面板的设计和制造,以及材料需求,均提出了较高的难度和挑战。
8K 120HZ 较4K 60HZ在诸如GOA等驱动电路中需要将诸如时钟信号线(CK)等走线设计更多的数量以及更小的电阻阻抗,以减小高频率工作造成的走线发热(WOA;Wire on array),这就需要更宽的GOA电路和更宽的CK走线,导致无法满足窄边框的需求。
技术问题
现有设计中,为了减小CK走线的阻抗,通常是增加CK走线的线宽和/或减小CK走线之间的线距,同时采用框胶设置于所述CK走线上(on bus line)的结构设计,此种结构因线距过小即金属镂空率较小,使得密封液晶的框胶在紫外光固化时固化不完全,导致液晶污染或是框胶整体粘着力不足,导致产品品味或性能问题。

现结合具体实施例对本申请的技术方案进行描述。
本申请提供一种显示面板,如图1-图2所示,包括封装区2和与所述封装区2相邻的框胶区1,所述显示面板包括:
相对设置的第一基板100和第二基板200;
驱动电路层300,设置于所述第一基板100靠近所述第二基板200的一侧,所述驱动电路层300包括位于所述封装区2内的驱动单元子层310、及与所述驱动单元子层310相连并延伸至所述框胶区1内的走线子层320;
液晶层400,设置于所述第一基板100与所述第二基板200之间且与所述封装区2相对应;及
框胶层500,设置于所述走线子层320与所述第二基板200之间且与所述封装区2相邻接,
其中,所述走线子层320包括多条相互平行的金属走线321,任一相邻两所述金属走线321之间均设有镂空部322,各所述镂空部322中,靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度大于等于任一其它所述镂空部322的宽度。
可以理解的是,目前,诸如8K 120HZ等极高分辨率、高刷新频率的显示面板中,既需要将GOA驱动电路中诸如时钟信号线(CK)等走线设计更多的数量以及更小的电阻阻抗,以减小高频率工作造成的走线发热,又需要满足窄边框的要求,使得时钟信号线(CK)等走线的排布更为紧密,此种结构因线距过小即金属镂空率低至15%,使得密封液晶的框胶在紫外光固化时无法充足照射从而固化不完全,导致液晶污染或是框胶整体粘着力不足。显然,本申请中,通过将靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度设置为大于等于任一其它所述镂空部322的宽度;也即是将各所述镂空部322中宽度最大的一所述镂空部322对应设置于靠近所述框胶层500与所述液晶层400交界处的位置,从而提高所述走线子层320在所述框胶层500与所述液晶层400交界处的镂空率,便于在通过紫外光对所述框胶层500固化时,充分保证所述框胶层500中靠近所述液晶层400一侧部分的完全固化,实现对所述液晶层400一定的封装效果,具体的,所述走线子层320在所述框胶层500与所述液晶层400交界处的镂空率大于等于40%,也即是所述镂空部322中宽度最大的一所述镂空部322的宽度值大于等于所述金属走线321宽度的40%。
承上,本申请中,所述驱动电路层300具体可以为GOA驱动电路,并且,所述第一基板100设有与所述驱动电路层300连接且位于所述封装区2内的TFT阵列层(图中未出示),为保证所述显示面板的窄边框设计,将所述框胶层500设置于所述走线子层320上,减少了对于所述显示面板边框宽度的要求。
值得注意的是,本申请中是将各所述金属走线321做非等间距的排布,通过调整不同位置的所述镂空部322的宽度,使得所述走线子层320上不同位置具备不同的镂空率,并将宽度最大的所述镂空部322设对应设置于靠近所述框胶层500与所述液晶层400交界处的位置,便于在制作过程中,充分保证通过紫外光对所述框胶层500中靠近所述液晶层400一侧部分的完全固化,此外,对于所述框胶层500中未能完全固化的部分,后续可采用一加热步骤使其逐步固化。
在一实施例中,各所述镂空部322至少划分为两镂空组30,每一所述镂空组30至少包括一所述镂空部322,任一两组所述镂空组30中,其中一靠近所述框胶层500与所述液晶层400交界处的所述镂空组30中的任一所述镂空部322的宽度大于另一远离所述框胶层500与所述液晶层400交界处的所述镂空组30中的任一所述镂空部322的宽度。显然,此种将各所述镂空部322分组的设置方式,不同所述镂空组30中具有不同的镂空率,可以理解的是,任一两组所述镂空组30中,其中一靠近所述框胶层500与所述液晶层400交界处的所述镂空组30中的任一所述镂空部322的宽度大于另一远离所述框胶层500与所述液晶层400交界处的所述镂空组30中的任一所述镂空部322的宽度,也即是各所述镂空组30中所述镂空部322的宽度根据所述镂空组30与所述框胶层500与所述液晶层400交界处的位置的距离进行设置,具体的,越靠近所述框胶层500与所述液晶层400交界处的所述镂空组30中所述镂空部322的宽度越大。此外,在任一至少包括两所述镂空部322的所述镂空组30中,各所述镂空部322的宽度均相等,可以保证在一所述镂空组30中各所述金属走线321呈等间隔均匀分布。
在一实施例中,如图1所示,所述镂空组30的数量为两组,其中一靠近所述框胶层500与所述液晶层400交界处的所述镂空组30中的所述镂空部322的宽度等于所述金属走线321的宽度;显然,将各所述镂空部322划分为两所述镂空组30,使该两所述镂空组30的镂空率具有较大差异化,其中一远离所述框胶层500与所述液晶层400交界处的所述镂空组30的镂空率较低,即将该所述镂空组30中各所述金属走线321进行紧密排布,便于为另一靠近所述框胶层500与所述液晶层400交界处的所述镂空组30预留空间,以使得该所述镂空组30中的所述镂空部322的宽度等于所述金属走线321的宽度,此时,该所述镂空组30的镂空率为100%,当然,该所述镂空组30中的所述镂空部322的宽度也可以大于所述金属走线321的宽度;具体的,该靠近所述框胶层500与所述液晶层400交界处的所述镂空组30中只包含一个所述镂空部322,且该所述镂空部322两侧的两所述金属走线321分别位于所述封装区2内和所述框胶区1内;在通过紫外光固化所述框胶层500时,可以使得所述框胶层500中靠近所述液晶层400一侧的部分受到紫外光充足的照射,从而更快的固化完全,便于对所述液晶层400封装。
在一实施例中,如图2所示,所述镂空组30的数量为四组,其中,靠近所述框胶层500与所述液晶层400交界处的所述镂空组30中的所述镂空部322的宽度大于等于所述金属走线321宽度的40%,即该靠近所述框胶层500与所述液晶层400交界处的所述镂空组30的镂空率大于等于40%,具体的,四组所述所述镂空组30的镂空率从小到大依次可以是10%、20%、30%和40%,如图2所示,各所述镂空组30种均只包含一所述镂空部322,可以理解的是,在采用紫外光固化所述框胶层500时,所述紫外光穿过所述镂空部322照射到所述框胶层500以使所述框胶层500固化,在此过程中,为保证所述框胶层500受到充分照射,需要保证所述走线子层320各处的镂空率至少达到40%,本实施例中,设置靠近所述框胶层500与所述液晶层400交界处的所述镂空组30的镂空率大于等于40%,以便于所述框胶层500中靠近所述液晶层400一侧的部分在紫外光固化过程中完全固化。此外,各所述镂空组30中均可包括多个所述镂空部322,在此不再赘述。
在一实施例中,如图2所示,任一相邻两所述镂空部322中,其中一靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度大于另一远离所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度;可以理解的是,各所述镂空部322的宽度与离所述框胶层500与所述液晶层400交界处的距离呈正相关,即离所述框胶层500与所述液晶层400交界处越近的所述镂空部322,其宽度越宽,从而使得所述走线子层320上越靠近所述框胶层500与所述液晶层400交界处的地方具备的镂空率越大,从而保证了所述框胶层500中越靠近所述框胶层500与所述液晶层400交界处的部分,通过紫外光固化的越完全。
在一实施例中,任一所述镂空部322的宽度均大于等于所述金属走线321宽度的10%,即所述走线子层320各处的镂空率至少大于等于10%。可以理解的是,如前所述,在采用紫外光固化所述框胶层500时,所述紫外光穿过所述镂空部322照射到所述框胶层500以使所述框胶层500固化,在此过程中,为保证所述框胶层500至少产生一定的固化效果,需要保证所述走线子层320各处的镂空率至少大于等于10%,以保证所述紫外光穿过各所述镂空部322后,均能使所述框胶层500产生一定的固化效果,也便于后续采用加热工艺对所述框胶层500中固化不完全的部分进行进一步固化操作。
综上,本申请显示面板通过将靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度设置为大于等于任一其它所述镂空部322的宽度;以保证所述走线子层320在所述框胶层500与所述液晶层400交界处的镂空率,使得所述框胶层500中靠近所述液晶层400一侧的部分固化完全,很好的对所述封液层进行密封,避免液晶层400的污染。
本申请还提供一种显示面板的制作方法,如图3所示,所述显示面板包括封装区2和与所述封装区2相邻的框胶区1;所述显示面板的制作方法包括以下步骤:
步骤S10:提供一第一基板100,在所述基板上形成驱动电路层300,所述驱动电路层300包括形成于所述封装区2内的驱动单元子层310、及与所述驱动单元子层310相连并延伸至所述框胶区1内的走线子层320;所述走线子层320包括多条相互平行的金属走线321,任一相邻两所述金属走线321之间均设有镂空部322;及
步骤S20:提供一第二基板200,在所述走线子层320上形成与所述封装区2相邻接的框胶层500,将所述第二基板200与所述第一基板100对合并通过所述框胶层500固定连接,在所述第一基板100与所述第二基板200之间形成与所述封装区2相对应的液晶层400;其中,各所述镂空部322中,靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度大于等于任一其它所述镂空部322的宽度。
可以理解的是,在一实施例中,所述走线子层320可以是通过在所述第一基板100上形成一金属层,然后通过蚀刻的方式使得所述走线子层320上形成多个所述镂空部322,通过控制蚀刻的位置使得各所述镂空部322中,靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度大于等于任一其它所述镂空部322的宽度,从而便于后续所述框胶层500中靠近所述液晶层400一侧的部分通过紫外光照完全固化。显然,整体的制作工艺流程均采用较为成熟的工艺,没有增加额外的工序,适于批量化的制作。
在一实施例中,所述步骤S20中,所述在所述走线子层320上形成与所述框胶区1相对应的框胶层500,包括:
在所述走线子层320上涂布与所述框胶区1相对应的框胶,采用紫外光穿过各所述镂空部322对所述框胶进行照射,至少使靠近所述封装区2一侧的部分所述框胶固化;及
对所述框胶采用一加热步骤,使所述框胶完全固化,以在所述走线子层320上形成与所述框胶区1相对应的框胶层500。
可以理解的是,在采用紫外光照的方式将所述框胶固化的过程中,由于所述走线子层320在靠近所述框胶层500与所述液晶层400交界处位置的镂空率较高,便于使所述框胶层500中靠近所述液晶层400一侧的部分完全固化,此时,所述框胶层500中未靠近所述液晶层400的部分由于所对应所述走线子层320镂空率较低的位置,使得所述框胶层500中未靠近所述液晶层400的部分未完全固化,本申请还可以通过额外增加一加热步骤,如烘烤等方式以使得所述框胶层500整体完全固化,从而实现诸如8K 120HZ等极高分辨率、高刷新频率的显示面板窄边框的需求,同时也保证了所述框胶层500对所述液晶层400的封装,避免了所述液晶层400被污染而造成显示异常的问题。
本申请的有益效果为:通过将靠近所述框胶层500与所述液晶层400交界处的所述镂空部322的宽度设置为大于等于任一其它所述镂空部322的宽度;以保证所述走线子层320在所述框胶层500与所述液晶层400交界处的镂空率,使得所述框胶层500中靠近所述液晶层400一侧的部分固化完全,很好的对所述封液层进行密封,避免液晶层400的污染;并且,整体结构在制作工艺上对原有制作工艺工序影响较小,适于批量生产。
综上所述,虽然本发明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发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
