一种应用于显示面板的软性电路板和显示装置 【技术领域】
本申请涉及显示技术领域，尤其涉及一种应用于显示面板的软性电路板和显示装置。
【背景技术】
显示器具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的显示器大部分为背光型显示器，其包括显示面板及背光模组(backlight module)。显示面板的工作原理是在两片平行的基板当中放置液晶分子，并在两片基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
其中，薄膜晶体管显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，薄膜晶体管显示器包含显示面板和背光模组，显示面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。显示面板是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，实现显示的目的。
COF(Chip On Flex，or，Chip On Film，覆晶薄膜)，将驱动IC固定于柔性线路板上晶粒软膜构装技术，是运用软质附加控制电路板作封装芯片载体将芯片与软性基板电路接合的技术。
目前曲面设计应用，因为显示面板的要进行弯曲，所以比较容易拉伤软性电路板，从而导致显示上的异常。
【发明内容】

其中，所述凹口设置在所述侧边上，所述凹口的一端与所述第一连接边的端点连接，所述凹口的另一端与所述第二连接边的端点连接。这样，将整个第一侧边或/和第二侧边设置为弧线段，适合没有设置凹口的那条侧边固定不弯曲，需要弯曲的那条侧边能够分散显示面板弯曲产生的扭力，随着软性电路板弯曲时的曲率的变化，弧线段能够动态的分散软性电路板上的受力拉扯点，使得软性电路板上的受力拉扯点分散开，从而有效的避免软性电路板的撕裂，有效的避免软性电路板与显示面板连接的位置被拉伤，进一步的避免显示面板被拉伤导致的不正常显示。
