随着显示技术的发展,液晶显示装置(Liquid Crystal Display,LCD)等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点,而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品,成为显示装置中的主流。现有市场上的液晶显示装置大部分为背光型液晶显示装置,其包括液晶显示面板及背光模组(Backlight Module)。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子,两片玻璃基板中间有许多垂直和水平的细小电线,通过通电与否来控制液晶分子改变方向,将背光模组的光线折射出来产生画面。
随着可穿戴应用设备如智能眼镜、智能手表等的逐渐兴起,显示行业对可挠曲显示器件的需求也不断增加。有机发光二极管显示器件(Organic Light Emitting Display,OLED)具有自发光不需背光源、厚度薄、边框窄等特点。面对OLED的竞争,传统TFT液晶显示屏加上LED面光源背光显示技术可以有效弥补自身的不足。
然而,现有技术的LED面光源背光显示器包括LED面光源及显示面板,所述LED面光源与显示面板LED通过柔性电路板组件(Flexible Printed Circuit Assembly,FPCA)形成电性连接,而面光源的LED驱动IC通常设置在柔性电路板组件上,柔性电路板组件需要额外设置一个连接器以使LED驱动IC与LED面光源上的LED芯片电性连接,这无疑压缩了柔性电路板组件的空间,且LED驱动IC与LED面光源上的LED芯片电性连接的走线难度较高,上述问题大大增加了制作成本。
