Abstract

The invention relates to a backlight module and a display device. The backlight module comprises an optical plate, a light source and a prismatic lens. The optical plate includes a light-emitting surface, a bottom surface opposite to the light-emitting surface, and a side surface connected between the light-emitting surface and the bottom surface. The light source is arranged on the bottom surface or side surface of the optical plate. The prismatic lens is arranged on the optical plate, a plurality of first strip-shaped microstructures are formed on the prismatic lens, the first strip-shaped microstructures face the optical plate, the first strip-shaped microstructures comprise ridge parts, and concave structures and / or convex structures are formed on the ridge parts.

Description

technical field [0001] The present invention relates to a backlight module and a display device, and in particular to a backlight module which improves the overall optical properties by improving the structure of a prism sheet and a display device including the backlight module. Background technique [0002] With the advancement of technology, electronic devices equipped with liquid crystal display (LCD) panels, such as mobile phones, tablets, notebook computers, car display devices, etc., have become indispensable items in modern life. Since the liquid crystal itself does not emit light, the LCD panel needs to use a backlight module as a backlight source. However, the existing backlight modules are prone to lack of uneven brightness and darkness, thereby affecting the image quality of the LCD panel. [0003] How to overcome the lack of uneven brightness and darkness of the backlight module to improve the overall optical properties of the backlight module has become the goa...
