Abstract

The invention provides a display device and a backlight module thereof. The backlight module comprises a light source, a light-transmitting plate, a reflective sheet, a reflective polarized light brightening film and a 1 / 4 wave plate, the reflector plate is arranged on one side of the light-transmitting plate; the reflective polarized light brightening film is arranged on the other side of the light-transmitting plate; and the 1 / 4 wave plate and the light-transmitting plate are arranged on the same side of the reflective polarized light brightening film. According to the application, the 1 / 4 wave plate is arranged on the side, provided with the light transmitting plate, of the reflective polarized light brightening film, so that the non-transmitted polarized light reflected by the reflective polarized light brightening film passes through the 1 / 4 wave plate and then becomes circular polarized light, the circular polarized light is reflected by the reflective plate and subjected to phase mutation, and the circular polarized light can be converted into polarized light capable of penetrating through the reflective polarized light brightening film after passing through the 1 / 4 wave plate; therefore, the backlight recovery efficiency is improved, and the display quality of the display panel is improved; in addition, the number of times that backlight generated by the light source penetrates through the reflection type polarized light brightening film is reduced, and the phenomenon that recycled backlight rays are yellowish is further avoided.

Description

technical field [0001] The present application relates to the technical field of display devices, and in particular, to a display device and a backlight module thereof. Background technique [0002] The backlight module is one of the important components of the liquid crystal display. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and evenly distributed light sources, so that the liquid crystal display can display images normally. At present, the display technology of liquid crystal displays has become mature, especially in the design of backlight modules. In addition to being applied to liquid crystal display devices such as liquid crystal displays and liquid crystal televisions, backlight modules can also provide light sources for display devices such as digital photo frames, electronic paper, and mobile phones. [0003] The backlight of an LCD (Liquid Crystal Display, liquid crystal display) is...
