Backlight module and display device thereof

Abstract

The invention provides a backlight module. The backlight module comprises a plurality of backlights, a rubber frame, an optical film and heat conduction partition walls located among the backlights. The heat conduction partition walls can conduct out the heat generated by a light source through the way of being in contact with a metal outer frame through a manner of penetrating through the rubber frame, or of being in direct contact with the bottom surface of the metal outer frame, or penetrating through the metal outer frame and the like. The heat conduction partition walls can be separately manufactured, or can be integrally manufactured with the rubber frame and an iron frame. According to the backlight module provided by the invention, through arranging the partition walls of the light source as a heat conduction structure, the heat emitted by the light source can be quickly conducted out, the temperature of the backlight module is reduced and the effect of the temperature of the backlight module on a display device is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight module with better heat dissipation performance and a display device thereof. Background technique [0002] Liquid crystal displays have the advantages of thinness, energy saving and no radiation, and are widely used in mobile communications and digital devices. Most liquid crystal displays are backlight liquid crystal displays, including a liquid crystal panel, a backlight module, and a casing. The liquid crystal display panel itself does not emit light, and needs the light source provided by the backlight module to display images normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device. [0003] Such as figure 1 As shown, the backlight module in the prior art is composed of light source 1', plastic frame 2', metal frame 3', optical film 4' and other components. When the backlight module is working, multiple light sources...

AI Technical Summary

Problems solved by technology

After the optical diaphragm accumulates heat, the thermal deformation of the diaphragm will cause defects such as optical stripes to appear on the light-emitting side of the display panel, which will affect the display quality

In addition, the heat accumulated inside the display device will also affect the electrical and optical devices in the liquid crystal panel, thereby affecting the display effect.

In recent years, liquid crystal display devices, especially liquid crystal display panels of mobile consumer products, have become smaller and smaller, and require more and more light and thin. The components in the corresponding backlight module are also more compact, and the remaining space for heat dissipation becomes smaller. Difficult to diffuse, affecting the display performance of the display device
