Abstract
The utility model discloses a backlight module and a display provided with the backlight module. The backlight module comprises a heat conduction device, a heat radiation block, a light source and a backboard. The heat conduction device is composed of a base layer and carbon nanometer layers arranged to cover the two opposite side surfaces of the base layer. The heat radiation block is connected with one end of the heat conduction device. The light source is connected with the other end of the heat conduction device relative to the heat radiation block. The backboard is connected with one end of the heat radiation block, wherein the end of the heat radiation block is far away from the light source. According to the technical scheme of the utility model, the heat conduction device is strong in transverse heat conduction capacity while poor in longitudinal heat conduction capacity. In this way, the heat conduction device is tightly attached to the heat-generating part of the light source, so that the heat emitted by the light source is absorbed and transversely guided to the part far away from the edge of the backlight module. Meanwhile, the heat is radiated to the surrounding environment through the heat radiation block. Therefore, the heat is prevented from being excessively transferred to the outer surface of the backlight module. The backlight module and the display provided with the backlight module have the advantages of simple structure and good heat dissipation effect.
