Description

一种液晶面板及其制作方法、显示装置 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种液晶面板及其制作方法、显示装置。
背景技术
覆晶薄膜(Chip On Film，COF)，即将芯片(IC)固定于柔性电路板(FPC)的晶粒软膜上，在众多显示面板如LCD、OLED等中，都要用到这种封装技术的芯片。这种芯片多用作显示驱动的源极驱动(Source Driver)和栅极驱动(Gate Driver)。在驱动电路中，COF一端连接到印制电路板(PCB)，负责接收印制电路板传输过来的数据信号，COF的另一端连接显示面板(Panel)，用于将IC输出的数据信号传输到显示面板上，以驱动显示面板进行显示。
具体地，COF与印制电路板和显示面板的连接是通过绑定(Bonding)工艺完成的，在LCD(Liquid Crystal Display，即液晶显示器)的制作过程中，出于液晶驱动的需要，需要预留驱动线路的绑定(即bonding)位置，传统的做法是将带有线路的TFT(Thin Film Transistor，薄膜晶体管)基板做得比上层的CF(color filter，彩色滤光片)基板稍大一些(通常大于1mm)，将需要的绑定位置的线路裸露出来，以便留出驱动线路的绑定位置，这样需要设置外框将绑定区盖住，以免被用户看到而影响显示外观。
近年来，随着LCD显示行业的不断发展，面板外观有逐渐变窄的趋势。诸如窄边框电视，是将边缘非显示区域做窄，边框采用更简洁、细致的造型，使产品更为美观。甚至有提出“无边框”面板概念，即去掉遮挡面板非显示区的外框，实现无边框显示，然而，由于TFT基板侧的绑定端比CF基板长，需要保留专门的外框以盖住绑定区的连接线路，影响窄边框化，无边框显示也无法实现。
发明内容

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参阅图1～图3，本发明实施例的显示装置包括液晶面板10和背光模组20，背光模组20设于液晶面板10的阵列基板12所在侧，彩膜基板11所在侧为出光面，彩膜基板11、阵列基板12外表面分别贴合有上偏光片P1、下偏光片P2。具体地，液晶面板主要包括彩膜基板11、阵列基板12、设于彩膜基板11与阵列基板12之间的液晶13、覆晶薄膜14、设于覆晶薄膜14上的驱动芯片15与电路板16，覆晶薄膜14一端贴合于阵列基板12端面，并与阵列基板12内的金属导线阵列120电连接，覆晶薄膜14的另一端与电路板16绑定，覆晶薄膜14弯折后，电路板16设于阵列基板12的背面所在侧。
彩膜基板11与阵列基板12贴合有覆晶薄膜14的端面平齐，覆晶薄膜14同时贴合于彩膜基板11与阵列基板12的端面，使得液晶面板具有平整的端面。阵列基板12端面与覆晶薄膜14之间粘附有导电胶层17，导电胶层17与金属导线阵列120电连接，彩膜基板11与阵列基板12之间的外围封装有框胶T，框胶T将液晶13封装于彩膜基板11与阵列基板12之间，以防止水汽进入。阵列基板12与框胶T的端面形成有导电网点18，阵列基板12位于框胶T内的金属导线阵列120引出至与导电网点18电连接，导电胶层17将导电网点18封装于其中，同时，覆晶薄膜14通过该导电胶层17粘贴在阵列基板12、框胶T以及彩膜基板11的端面。
本实施例中，导电胶层17为ACF(Anisotropic Conductive Film，即异方性导电胶膜)胶，导电网点18为Ag等导电性能较好的材料。
如图4所示，在另一种实施方式中，在阵列基板12上贴合有覆晶薄膜14的一端，彩膜基板11的宽度大于阵列基板12的宽度，即彩膜基板11的端面伸出于阵列基板12端面，导电胶层17只贴合在阵列基板12与框胶T的端面，覆晶薄膜14贴合在导电胶层17表面，彩膜基板11遮挡在覆晶薄膜14上方，可以避免覆晶薄膜14暴露而需要额外设计框架结构遮挡。
如图3所示，本实施例的显示装置中，背光模组20包括导光板21、设于导光板上表面的光学膜片组22以及背板23，背板23包括用于承载导光板21的底面部分、用于固定光源200的侧面部分以及用于承载液晶面板10的顶面部分，光学膜片组22设于导光板21上，且其端面与背板23的顶面部分端面抵接，液晶面板10通过遮光胶粘贴在背板23的顶面部分。背板23的底面部分与导光板21之间还可以设置一层反射层24，该反射层贴合于导光板21底面并延伸至抵接在背板23的侧面部分，可以最大限度地将光源200投射的光线反射回导光板，背板23的底面部分底部还可开设有用于供覆晶薄膜14和电路板16容纳的底面凹陷部，背板23的侧面部分还可开设有供驱动芯片15嵌入的侧面凹陷部，使得背板23既作为光源200的固定和散热件，又作为覆晶薄膜14、驱动芯片15和电路板16的容纳件，使得显示装置的结构更加紧凑。
如图5和6，本发明还提供了一种液晶面板的制作方法，包括：
S01、切割母版，形成多个液晶盒；
S02、利用磨削装置M对液晶盒设置有金属导线阵列120的一端的端面打磨，以提高表面光洁度；
S03、在各液晶盒设置有金属导线阵列120的一端制作导电网点18，使导电网点18与金属导线阵列120电连接；具体是，利用喷头P在打磨后的液晶盒端面喷印银胶，形成点状阵列，每一个银胶点与金属导线阵列120的至少一条金属导线导通，以此实现多通道的信号接入，藉由喷印的喷射力度，银胶液滴在附着在面板端面的时候会顺势往框胶T与阵列基板12缝隙内进行渗入，可更好的与设置在阵列基板12上的金属导线端子进行结合；
S04、分别在液晶盒的上下表面贴附上偏光片P1、下偏光片P2；
S05、在液晶盒端面贴合带驱动芯片15与电路板16的覆晶薄膜14，使覆晶薄膜14与导电网点18导通。在液晶盒端面贴合带驱动芯片15与电路板16的覆晶薄膜14时，先在覆晶薄膜14与液晶盒设置有金属导线阵列120的一端设置导电胶层17，然后采用热压的方式利用热压头Y使导电胶层17贴合于液晶盒端面，使覆晶薄膜14与液晶盒之间保持良好的电性连接。
切割后的液晶盒中，每个彩膜基板11与阵列基板12贴合有覆晶薄膜14的端面平齐，覆晶薄膜14同时贴合于彩膜基板11与阵列基板12的端面，导电胶层17粘贴在阵列基板12、框胶T以及彩膜基板11的端面。或者，彩膜基板11的端面伸出于阵列基板12端面，导电胶层17只贴合在阵列基板12与框胶T的端面，覆晶薄膜14贴合在导电胶层17表面，彩膜基板11遮挡在覆晶薄膜14上方。
本发明在对液晶面板进行信号接入时，采用端面绑定的方式将覆晶薄膜压合在阵列基板的端面，从而实现阵列基板内的金属导线阵列的导通，可以避免TFT基板侧延伸出较长的绑定区，有利于显示装置实现超窄边框或无边框。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
