Abstract

一种背光模块及显示设备。背光模块包括框架单元(2)、复数个发光单元(3)、第一光学单元(4)及第二光学单元(5)。框架单元(2)包括金属背框(21)，金属背框(21)具有第一放置部(215)，及间隔于第一放置部(215)的第二放置部(216)，第一放置部(215)与第二放置部(216)的高度不同。发光单元(3)设置于第一放置部(215)上，另一发光单元(3)设置于第二放置部(216)上。第一光学单元(4)用于接收设置于第一放置部(215)的发光单元(3)的光线，第二光学单元(5)用于接受设置于第二放置部(216)的发光单元(3)的光线。通过金属背框(21)的结构设计，使发光单元(3)都能直接与金属背框(21)接触，提升散热效率。
