Abstract

The invention discloses a backlight module. The backlight module comprises a substrate, a plurality of light emitting diodes and a plurality of optical patterns, wherein the light emitting diodes arearranged on the substrate, the optical patterns are located on the sides, opposite to the substrate, of the light emitting diodes and correspond to the light emitting diodes respectively, and each optical pattern is formed by intersecting two long geometric patterns. The light-emitting diodes have an arrangement direction, and the included angle between the long axis of the long geometric patternsand the arrangement direction is larger than 0 degree and smaller than 90 degrees.

Description

Technical field [0001] The present invention relates to a backlight module, in particular to a backlight module with optical patterns and uniform light patterns. Background technique [0002] In daily life, many electronic devices with display devices have become indispensable products in people's lives, such as smart phones, tablet computers, TVs, game consoles, cameras, etc. With the development of science and technology, these electronic devices are gradually evolving towards ultra-thin and lightweight design methods. For display devices, how to achieve the desired display effect while shrinking the frame and reducing the thickness and other specifications? The design of the optical structure will be a major focus. [0003] The backlight module is a very important element in the optical structure of the display device. Taking the traditional direct backlight module as an example, in order to make the point-shaped light-emitting diode light source achieve the effect of uniform d...
