Abstract

The invention provides a backlight module and a liquid crystal display comprising the backlight module. A liquid crystal box array substrate in the prior art serves as a light guide plate, and therefore the liquid crystal display is further thinner and the production cost is reduced. A first refractor and a second refractor are deposited on the light guide plate, the refractive index of the first refractor is larger than the light guide plate and the second refractor, and therefore the light conducts total reflection on the second refractor and a faying surface of the first refractor, a good full reflection effect is achieved, and light leakage phenomenon is reduced and out-light uniformity in all positions in the crystal liquid display is guaranteed. Besides, the first refractor and the second refractor replace a low refractive index film and the manufacture cost of the backlight module is saved.

Description

technical field [0001] The invention relates to the field of manufacturing liquid crystal displays, in particular to a backlight module and a liquid crystal display. Background technique [0002] Currently, liquid crystal displays are widely used in the field of flat panel displays. Among them, the liquid crystal display panel must provide the required surface light source by the backlight module. In the prior art, the design of the backlight module is usually to add a layer of low-refractive index film on the top of the light guide plate, so that the light emitted from the side light source is fully reflected on the bonding surface of the low-refractive index film and the light guide plate. Reflection, so that light can be transmitted in the light guide plate for a long distance. However, at present, it is difficult to obtain a refractive index film with a sufficiently low refractive index (less than 1.4), so that light leakage is prone to occur when the light is transmit...
