Description

背光面光源及液晶显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种背光面光源及液晶显示装置。
背景技术
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。由于液晶显示面板本身不发光，需要借由背光模组提供的光源来正常显示影像，因此，背光模组成为液晶显示装置的关键组件之一。背光模组依照光源入射位置的不同分成侧入式背光模组与直下式背光模组两种。
现有技术中，请参阅图1，存在一种异形液晶显示装置，其包括液晶面板100和背光模组200，所述液晶面板100设有第一过孔120，所述背光模组200对应所述第一过孔120的位置设有第二过孔240。如图2所示，当所述背光模组200为侧入式背光模组时，所述背光模组200的导光板220包括对应所述第一过孔120的第三过孔242。第三过孔242附近容易产生暗区280，LED 260发出的光线无法到达的该暗区280，由此影响用户使用的舒适度。为了解决上述问题通常采用传统的直下式背光模组，如图3所示，直下式背光模组300包括LED基板310、设于所述LED基板310上的数个LED 360以及设于数个LED 360上的光学膜片330，所述光学膜片330包括对应所述第一过孔120的第四过孔334，所述LED基板310包括对应所述第一过孔120和第四过孔334的第五过孔340，所述光学膜片330用于将数个LED 360发出的光线均匀扩散形成面光源，故传统的直下式背光模组厚度较厚，无法实现异形液晶显示装置的薄型化。
迷你发光二极管(Mini LED)显示装置是一种在一个基板上集成微米级的LED阵列作为显示像素来实现图像显示的显示装置，其每一个像素均可定址、单独驱动点亮，属于自发光显示器，其耗电量小，且色彩饱和度 接近OLED，很多厂商将其作为目前的研究重点。
