Abstract

The invention discloses a backlight module which comprises a back panel, a plurality of light source sets and a plurality of light guiding members. The light source sets are arranged on the back panel at intervals, and each light source set comprises a plurality of point light sources. The light guiding members are configured on the back panel and respectively located beside the light sources sets. Each light guiding member extends along a predetermined direction and is provided with a bottom surface, a first reflecting surface and a second reflecting surface. Each bottom surface faces the back panel, each first reflecting surface extends from the bottom face to the upside of the point light source of the corresponding light source set, and each first reflecting surface is a curved surface. Each second reflecting surface is connected between each bottom surface and each first reflecting surface. The luminous surfaces of the point light sources in each light source set face the first reflecting surface of the corresponding light guiding member. The backlight module has the advantages of thin thickness and power saving. In addition, the invention additionally provides a display with the backlight module.

Description

technical field

[0001] The present invention relates to a surface light source device, and in particular to a backlight module and a display with the backlight module. Background technique

[0002] With the advancement of flat panel display technology and the advantages of light weight, small size and power saving of flat panel displays, flat panel displays have become more and more popular. Common flat panel displays include liquid crystal display, plasma display panel (PDP), organic light emitting diode display (OLED display) and electrophoretic display (EPD), among which the penetration rate of liquid crystal display is Highest.

[0003] The liquid crystal display includes a liquid crystal display panel (LCD panel) and a backlight module, wherein the backlight module is used to provide a surface light source to the liquid crystal display panel. Traditional backlight modules use cold cathode fluorescent lamps (cold cathode fluorescent lamps, CCFL) as light sources, but t...
