Abstract

It is an apthototropism mode set comprising a linear light source and a frame, wherein, the linear light source comprises a light body and electrodes located on both ends of the light body and the electrodes of linear light source are electrically connected with the frame. And the frame is located at least one clamp to hold the linear light source body and to contain the linear light source in the frame.

Description

【Technical field】 [0001] The invention relates to a surface light source device, in particular to a backlight module applied to a large-size liquid crystal display. 【Background technique】 [0002] Since the liquid crystal in the liquid crystal panel itself does not have luminous characteristics, in order to achieve the display effect, it is necessary to provide a surface light source device for the liquid crystal display panel, such as a backlight module, whose function is to supply a surface light source with sufficient brightness and uniform distribution to the liquid crystal panel. [0003] Liquid crystal display devices are widely used, and one of the important applications is large-size displays, such as liquid crystal televisions (LCD TVs). The backlight module of a large-size liquid crystal display device needs to be equipped with multiple light sources (such as cold-cathode fluorescent lamps). Therefore, it is a development trend of large-size display devices to modu...
