US 2010/0246164 A1 · Hollow Edge-Type Backlight Module with Light-Emitting Array

Abstract

A hollow edge-type backlight module with a light-emitting array and a display apparatus containing the same are disclosed. The hollow edge-type backlight module mainly utilizes a hollow reflection structure to replace a light-guide plate structure, and forms a light-emitting unit by collaborating with an edge-type light source, and forms a light-emitting array by appending together a plurality of light-emitting units. The reflection structure of each light-emitting unit has a horizontal surface and a reflective surface connected to the horizontal surface, wherein there is an angle included between the reflective surface and a surface extended from the horizontal surface, and the light source is disposed adjacent to the horizontal surface. A diffuser of the hollow edge-type backlight module is disposed above the reflective surface and the horizontal surface, and the diffuser, the light source, the horizontal surface and the reflective surface define at least one air cavity.
