Description
technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] As an important part of the liquid crystal display device, the backlight module is used to provide a light source with sufficient brightness and uniform distribution to the liquid crystal display panel. Backlight modules include side-type backlight modules and direct-type backlight modules. Compared with side-type backlight modules, direct-type backlight modules have advantages such as high contrast, which has become a development trend in recent years. At present, blue light-emitting diodes are usually used as light sources in direct-lit backlight modules, and a color conversion structure is used to convert the blue light emitted by the blue light-emitting diodes into white light required by the liquid crystal display panel. However, the existing color conversion structure is small ...
