Embodiment Construction

[0012] The main spirit of the present invention is to design an embedding groove on the plastic frame of the backlight module, and use the embedded method to fix the light source on the plastic frame. The light source is fixed.

[0013] FIG. 1 is an exploded view of a liquid crystal display unit 10 of the present invention. As shown in the figure, the liquid crystal display unit 10 includes a backlight module 11 and a liquid crystal panel 12 . The backlight module 11 includes a plastic frame 13 , a light guide plate 14 and a light source 15 . Both the liquid crystal panel 12 and the light guide plate 14 are disposed in the plastic frame 13 . The plastic frame 13 has a slot 16 . A side of the light guide plate 14 has a light incident surface 17 . The light source 15 is embedded in the embedding groove 16 and closely combined with the plastic frame 13 .

[0014] FIG. 2 is an exploded view of the plastic frame 13 and the light source 15 of the present invention before being ...

Abstract

The present invention provides a backlight module which can be used in liquid crystal display. Said backlight module includes the following components: a frame, a light-conducting plate and a light source with a circuit board and a luminous element. Said invention also provides the concrete structure of the above-mentioned every component and their connection mode.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] Liquid crystal display is a common electronic product, which is used in electronic devices such as personal computers and mobile phones to display images and texts. A liquid crystal display unit in a liquid crystal display includes a backlight module and a liquid crystal panel. The backlight module is used to carry the liquid crystal panel and provide light required by the liquid crystal panel. [0003] According to the existing technology, when designing small and medium-sized backlight modules, the light source circuit board is usually fixed on the plastic frame of the backlight module by means of glue. This method of gluing requires the use of additional materials (such as double-sided tape), and position calibration is required during lamination. Furthermore, as the use time...
