Abstract

The invention discloses a side entry type backlight module for improving taste. The side entry type backlight module for improving taste comprises a light guide plate, a side entry type light source arranged at one side of the light guide plate, a reflective sheet arranged at the bottom of the light guide plate and a prismatic lens arranged above the light guide plate; the prismatic lens is arranged at one side, closed to the side entry type light source, of the backlight module and faces the light guide plate. The invention further provides a display device. The upper portion of one side, closed to the side entry type light source, of the backlight module is provided with the prismatic lens, the prism surface of the prismatic lens faces the light guide plate, so that the brightness of light reflected from the reflective sheet to one side, closed to the side entry type light source, of the light guide plate is weakened, the optical taste of the backlight module is thus improved, and an obvious bright line does not appear on the side closed to the light.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a side-entry type backlight module and a display device with improved taste. Background technique [0002] The structure of the traditional side-type backlight includes LEDs, light guide plates, reflectors, optical membranes, and mechanism positioning structures. The light guide plates are placed directly above the reflectors with a certain gap between them. [0003] In order to meet modern people's pursuit of high-quality, ultra-thin TV and ultimate vision, higher requirements are put forward for product thickness. Therefore, people have conceived various new types of backlight modules, and one of the structures differs from the traditional structure in that : Use optical glue (OCA) to attach the reflective sheet to the surface of the light guide plate, so that the overall thickness is greatly reduced. However, sticking the light guide plate with the reflector will bring a cer...
