Abstract

The invention belongs to the technical field of lenses, and particularly relates to a lens, a backlight module and terminal equipment, the lens comprises a lens main body and a reflector, and the lens main body is provided with a reflection cavity for accommodating the reflector; a refracting surface which is at least used for refracting and reflecting light entering from the bottom of the lens main body to the position above the lens main body is formed on the outer wall of the peripheral side of the lens main body, and a first reflecting surface which is at least used for reflecting the light entering from the bottom of the lens main body to the peripheral side of the lens main body is formed on the cavity wall of the reflecting cavity of the reflecting body. The refracting surface is formed on the outer wall of the peripheral side of the lens main body, so that part of light incident from the bottom of the lens main body can be refracted to the area above the lens through the top surface of the lens and the refracting surface, the light emitting performance above the lens is improved, and the first reflecting surface enhances the light reflecting capacity of the peripheral side of the lens; therefore, the lens can obtain good light reflection performance without forming a large-area reflection surface, and the lens is easy to miniaturize.

Description

technical field [0001] The present application belongs to the technical field of lenses, and in particular relates to a lens, a backlight module and a terminal device. Background technique [0002] The lens is a key material in the backlight system of the liquid crystal display, which can diffuse the light generated by the LED light source to ensure the display brightness of the liquid crystal display. Existing lens types mainly include reflective lenses, which mainly reflect light through the upper surface of the lens and disperse it through the side surface. [0003] In the prior art, reflective lenses use the configuration of the lens itself to reflect light to its surrounding sides. One side of the reflective surface formed by the lens is made of lens material, and the other side is made of air. Due to the refraction of the air, If the rate is small, this will also lead to poor light reflection effect on the reflective surface. In order to pursue the reflection performa...
