Abstract

The present invention relates to a prism sheet, a backlight module unit and a liquid crystal display device. One surface of prism sheet comprises a plurality of light collecting units. The plurality of light collecting units comprise a plurality of light radiating surfaces which comprises a plurality of micro-structures for diffusing light. The light radiating homogeneity degree of prism sheet is high.

Description

technical field [0001] The invention relates to a prism sheet, a backlight module and a liquid crystal display device using the prism sheet. Background technique [0002] In recent years, liquid crystal display devices have been widely used in fields such as monitors, LCD TVs, mobile phones, and notebook computers due to their advantages of thinness, lightness, small footprint, and low radiation, and have gradually become the mainstream of display products. A liquid crystal display device generally includes a liquid crystal display panel and a backlight module for providing planar light to the liquid crystal display panel. [0003] see figure 1 , is a three-dimensional exploded schematic diagram of a liquid crystal display device in the prior art. The liquid crystal display device 1 includes a liquid crystal display panel 11 and a backlight module 12 adjacent to the liquid crystal display panel 11 . [0004] The backlight module 12 includes a light guide plate 13 , a refl...
