Problems solved by technology

However, because the cutting will affect the edge of the fluorescent film layer, the concentration of the fluorescent material will be uneven and the fluorescent material will be easily corroded and deteriorated by water and oxygen, resulting in a failure edge.
Therefore, the blue light emitted by the blue LED chip will directly pass through the invalid edge of the fluorescent film layer, causing the display image in the edge area of ​​the liquid crystal display device to be bluish, thereby affecting the display effect of the product and the visual experience of the user.

Abstract

The embodiment of the present invention discloses a backlight module and a display device, wherein the backlight module includes: a backboard, the backboard includes a bottom board and side boards; an LED light source, the LED light source includes a substrate and LED lamp beads electrically connected to the substrate , the LED lamp bead is located on the side of the substrate away from the bottom plate; the heat dissipation film layer is located on the side of the bottom plate close to and / or away from the substrate, and the heat dissipation film layer includes a hollow area and a first area, and the first area surrounds the hollow area . The backlight module and the display device provided by the present invention can effectively solve the problem that the displayed image in the edge area of ​​the liquid crystal display device is bluish.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Liquid crystal display devices are widely used in various display devices due to their advantages of thinness, lightness, low energy consumption, and no radiation. The liquid crystal display device includes a liquid crystal display panel and a backlight module that provides a light source for the liquid crystal display panel. The backlight module usually includes a blue LED chip that can emit blue light and a fluorescent film layer. The fluorescent material (such as phosphor powder or quantum dots, etc.) in the fluorescent film layer can be excited by blue light to produce red light and green light. These red light and green light After mixing with the blue light emitted by the blue LED chip, the white light required for image display is generated. In the prior art, when making a liquid crystal display devi...
