如图4所示,本申请还提供一种防静电的显示面板的制备方法流程,所述方法包括:
S10,提供一TFT阵列基板40,所述TFT阵列基板40包括显示区域41,在靠近所述显示区域41的下方边缘处上沿着第一方向D1绑定一柔性电路板42,所述柔性电路板42上固定有驱动芯片43。
具体的,所述S10还包括:
首先,提供一TFT阵列基板40,所述TFT阵列基板40包括显示区域41,在靠近所述显示区域41的下方边缘处上沿着第一方向D1将所述TFT阵列基板40、驱动芯片43及柔性电路板42进行绑定,所述柔性电路板42通过异方性导电胶膜绑定在所述TFT阵列基板40上,而所述驱动芯片43也通过所述异方性导电胶膜绑定在所述柔性电路板上。
具体地,所述异方性导电胶膜是同时具有接着、导电、绝缘三大特性的半透明高分子接续材料,可以提供细间距,高可靠性冷互联。所述异方性导电胶膜的特点在于纵向(Z方向)受力方向电气导通,而在横向平面(X、Y方向)具有明显的高阻抗特性。所述异方性导电胶的主要成分为掺有许多导电粒子,膜厚在数十微米左右的黏合剂,作为保护作用还加了一层底膜。导电粒子为表面镀镍镀金的塑料粉末,中心为塑胶球,在外镀镍金。所述异方性导电胶膜要发生作用必须经过热压,即通过温度、时间、压力三个要素使得所述异方性导电胶膜胶固化,导电粒子爆破达到导通效果,如图4A所示。
S20,提供一静电释放电路,将所述驱动芯片上的引脚与所述静电释放电路电连接,使所述引脚与所述静电释放电路组成一闭合回路。
具体的,所述S20还包括:
所述静电释放电路50由两个或两个以上的短路棒51以及金属线52构成;每一所述短路棒51的第一端511与对应的所述引脚电连接,每一所述短路棒51的第二端512通过所述金属线52电连接;所述驱动芯片43沿着第一方向D1设置,所述短路棒51垂直于所述第一方向D1设置,相邻的两所述短路棒51之间的距离相等;所述引脚包括芯片输入引脚以及芯片输出引脚,所述芯片输入引脚与对应的所述短路棒51电连接,所述芯片输出引脚与对应的所述短路棒51电连接;所述驱动芯片43上的所述引脚与所述静电释放电路50电连接,使所述引脚与所述静电释放电路组成一闭合回路,如图4B所示。
S30,在所述TFT阵列基板40上设置一围成矩形框状的切割线60,所述切割线60沿着所述第一方向D1穿过所述静电释放电路50,使用切割机沿着所述切割线60切割所述TFT阵列基板40,所述静电释放电路50断开,得到所述防静电的显示面板。
具体的,所述S30还包括:
首先,在所述TFT阵列基板40上设置一围成矩形框状的切割线60,所述切割线60包括第一子切割线61、第二子切割线62、第三子切割线63以及第四子切割线64,所述第一子切割线61以及所述第三子切割线63沿着所述第一方向D1平行设置,所述第二子切割线62以及所述第四子切割线64沿着垂直于所述第一方向D1平行设置;所述第三子切割线63穿过所述短路棒51。由于在切割过程中极易产生大量静电,所述驱动芯片43的所述引脚易吸引静电;所述引脚将吸引到的静电引流到所述静电释放电路50中,面板切割时将所述短路棒51切断,断开相邻的所述引脚,以保证后续模组正常使用,有效保护了窄边框显示面板内部信号线,如图4C所示。
本申请的防静电的显示面板以及制备方法,能在边框边窄的情况下增加产品的静电防护能力。
本申请的有益效果为:本申请所提供的防静电的显示面板及制备方法,将驱动芯片上的引脚与一静电释放电路组成一闭合回路,有效保护了窄边框显示面板内部信号线,进一步降低了显示面板被静电击伤的风险,更进一步提高了产品良率。
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。
