  • Patent number: 11126035
    Abstract: A backlight module and a liquid crystal display device are provided. The heat in the heat-accumulation region of the liquid crystal display panel is diffused into periphery of the heat sink in the chamber through the plurality of first through holes by using air as a medium, and the heat sink dissipates heat. Therefore, temperature in the heat-accumulation region of the liquid crystal display panel is lowered, and avoids the problem that service life of the liquid crystal display device becomes short due to high local temperature of the heat-accumulation region.

The waveguide illumination system further includes one or more elongated light coupling elements attached to a broad-area surface of the substrate with a good optical contact and disposed in registration with the respective light sources. Light emitted by the light sources is received on the elongated light coupling elements and is propagated along the longitudinal axis of the elements in response to optical transmission and a total internal reflection resulting in coupling at least a substantial portion of such light into the waveguiding substrate. The coupled light is distributed over the waveguiding substrate and emitted from a predefined area of the substrate's surface.
