Embodiment Construction

[0017] The optical plate of the present invention and the backlight module using the optical plate will be described in further detail below in conjunction with the accompanying drawings and multiple embodiments.

[0018] Please refer to FIGS. 2 and 3 together. The first preferred embodiment of the present invention provides a backlight module 30 which includes a reflective plate 31, a plurality of lamp tubes 35 and an optical plate 32. The optical plate 32 includes a transparent substrate 321 and a diffusion layer 322. The transparent substrate 321 includes a light-emitting surface 3213 and a connecting surface 3211 opposite to the light-emitting surface 3213. The connecting surface 3211 is formed with a plurality of elongated grooves 3215. The diffusion layer 322 is attached to the connecting surface 3211 and fills the plurality of grooves 3215. The reflecting plate 31 is opposite to the optical plate 32 and the diffusion layer 322 faces the reflecting plate 31. The lamp tube 35...

Abstract

An optical plate, which includes a transparent substrate and a diffusion layer, the transparent substrate includes a light-emitting surface and a connecting surface opposite to the light-emitting surface, the transparent substrate is formed with a plurality of elongated grooves on the connecting surface, The diffusion layer is attached to the connection surface and fills the plurality of grooves. The backlight module adopting the optical plate has the characteristics of thin thickness.

Description

Technical field [0001] The invention relates to an optical plate applied to a liquid crystal display device and a backlight module adopting the optical plate. Background technique [0002] In recent years, liquid crystal displays have been widely used due to their light, thin, small and low power consumption characteristics. Since the liquid crystal display panel itself does not have light-emitting characteristics, the backlight module needs to provide a backlight tube for it to realize the display function of the liquid crystal display panel. [0003] Please refer to FIG. 1, which is an exploded schematic diagram of the existing backlight module 10. The backlight module 10 includes a prism sheet 12, a diffuser sheet 13, a diffuser plate 14, a plurality of lamp tubes 15 and a reflector plate 11. The lamp tubes 15, the diffuser plate 14, the diffuser sheet 13, and the prism sheet 12 are arranged in sequence Above the reflector 11. Among them, the diffuser plate 14 has a relatively...
