Abstract
The invention discloses a backlight source, a backlight module and a manufacturing method thereof as well as a display device and aims at reducing the thickness of the backlight source and implement light and thinning development of the display device. The backlight source comprises a back plate, a reflection sheet arranged on the back plate, a light guide plate arranged on the reflection sheet, a light bar arranged on the light incoming side of the light guide plate and a frame arranged on the reflection sheet, provided with the contact surface of the reflection sheet and capable of surrounding the light bar, wherein the material of the light guide plate is transparent glass; the contact surface between the reflection sheet and the back plate and the contact surface between the light guide plate and the frame are fixed with each other via a lamination process.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a backlight source, a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] At present, light weight, thinner and more aesthetically pleasing have become the development trend of the display industry in the future. In order to achieve the above purpose, the backlight source in the prior art will adopt a thinner design method when designing. [0003] Backlight sources in the prior art adopt two types of backlight designs: direct-type and side-type. Among them, the design principle of the direct type backlight is to arrange the light source under the diffusion plate. Since the thickness of the direct-type backlight is relatively thick, the side-type backlight has become the mainstream of the backlight with the reduction in weight, thickness and appearance. The side-type backlight is designed by setting the light source on the side ...
