Abstract

The present invention relates to a backlight module and a LCD device. The backlight module comprises at least one luminous unit. The luminous unit comprises a plurality of luminous sources and a light mixer. The light mixer comprises a plurality of light guide elements corresponding to a plurality of luminous sources and a light mixing element. The luminous sources emit light in different colors. The light guide elements guide the light in different colors emitted by a plurality of luminous sources into the light mixing element. The light in different colors is mixed into white light in the light mixing element.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] Liquid crystal display devices have the characteristics of light and thin, low power consumption and less radiation, and are widely used in monitors, LCD TVs, mobile phones and notebook computers, and become the mainstream of displays, but at the same time, higher requirements are put forward for their display brightness and color display effect . Since the liquid crystal itself does not emit light, a backlight module is required to provide a light source for it. Backlight modules are usually divided into direct-type backlight modules and edge-type backlight modules. At present, the light sources of backlight modules mainly use cold cathode ray tubes and light-emitting diode arrays. Light-emitting diodes have been widely used in backlight modules due to their high color saturation, mercury-free, and long lifespan. ...
