一种超薄LED背光源组件
本专利技术属于液晶显示
,具体涉及一种超薄LED背光源组件。
技术介绍
背光源是提供液晶显示器面板的光源,随着液晶显示技术的不断发展,液晶显示器特别是彩色液晶显示器的应用领域也在不断拓宽,液晶显示器为非发光性的显示装置,须藉助背光源才能达到显示的功能,背光源性能的好坏除了会直接影响液晶显示器的显像质量外,背光源的成本占液晶显示模块的30-50%,所消耗的电力更占模块的75%,高精细、大尺寸的液晶显示器必须有高性能的背光技术与之配合。背光源目前主要有EL、CCFL及LED三种背光源类型,依光源分布位置不同则分为侧光式和直下式,随着液晶显示技术的不断发展,背光技术的高性能化,如高亮度化、低成本化、低耗电化、轻薄化等,成为背光源的主要发展方向。
