Background technology
Along with the development in epoch, the demand of electronic equipment is grown with each passing day by the mankind, thus also having driven the fast development of lcd technology.Liquid crystal indicator has the features such as low in energy consumption, volume is little, light weight, and enjoys the favor of user.Liquid crystal indicator includes display panels and backlight module, and the contiguous display panels of backlight module is arranged, for providing area source for described display panels.Generally including light source and light guide plate in backlight module, the light sent from light source enters the incidence surface of light guide plate and enters in light guide plate, via after the diffusion of light guide plate by the exiting surface outgoing of light guide plate, thus providing area source for display panels.Light guide plate is as optical module conventional in liquid crystal indicator, again because of the development of technology of quantum dots so that it becomes the focus of people's research.
Application for a patent for invention CN104763949A discloses a kind of backlight module and display device, described backlight module includes: light guide plate, the monochromater of light guide plate incident side, the grating of light guide plate exiting surface, light guide plate exiting surface quantum dot plate, the described monochromatic light after diffraction is converted to white light by described quantum dot plate.Light guide plate, grating, quantum dot plate are mechanically combined by from level to level, not only assemble trouble, and need large-area grating and quantum dot plate film, relatively costly.
Utility model content
Problem to be solved in the utility model is the deficiency overcoming prior art to exist, it is provided that a kind of grating type light guide plate based on quantum dot.
Concrete scheme is as follows:
A kind of grating type light guide plate based on quantum dot, at least one side of light guide plate is for making the incidence surface of light, the upper and lower plate face of light guide plate is the reflecting surface of reflection light and the exiting surface making uniform light outgoing respectively, described exiting surface is provided with multiple site, each site is equipped with optical grating construction, and all recess at optical grating construction fill the transparent filler thing containing quantum dot.
Further, described optical grating construction has and is spaced and parallel multiple rectangular recess.
Further, the described transparent filler thing containing quantum dot is to be filled in each rectangular recess, and the refractive index of the transparent filler thing that should contain quantum dot is different from the refractive index of light guide plate.
Further, the described transparent filler thing containing quantum dot is filled to concordant with the exiting surface of site.
Further, the optical grating construction at described site place is all and arranges in the same direction.
Grating type light guide plate based on quantum dot described in the utility model is possible not only to obtain very pure white light, and the briliancy of light can be strengthened, its design utilizes optical grating construction to derive light dexterously, the diffraction of optical grating construction makes light concentrate on light direction, reaching the effect of blast, light is changed into pure white light through quantum dot simultaneously.Optical grating construction, quantum dot are combined in light guide plate surface by the grating type light guide plate based on quantum dot described in the utility model dexterously, save space, reduce cost, have and promote the use value.
