Backlight module, display panel and preparation method of backlight module

Abstract

The embodiment of the invention provides a backlight module, a display panel and a preparation method of the backlight module, the backlight module comprises a lamp panel and a plurality of adhesive layers arranged on the lamp panel in a stacked mode, and the lamp panel comprises a substrate and a plurality of point light sources distributed on the substrate. The plurality of adhesive layers comprise a light scattering layer covering the plurality of point light sources; a diffusion layer which coats one surface, deviating from the lamp panel, of the light scattering layer; and a correction layer which coats one surface, deviating from the light scattering layer, of the diffusion layer, and is used for correcting the light output by the diffusion layer towards the normal direction of the light emitting surface of the correction layer. According to the embodiment of the invention, the plurality of optical adhesive layers are arranged on one side of the lamp panel, so that the backlightmodule is thinned on the premise of not influencing the quality of the backlight module, and the effects of high brightness and narrow frame are achieved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a backlight module, a display panel and a method for preparing the backlight module. Background technique

[0002] With the development of science and technology, the requirements for backlight products are getting higher and higher; it is the current mainstream to require backlights to be ultra-thin, bright, and narrow bezel. For the design of the ultra-thin and narrow frame of the backlight, various new methods are emerging in an endless stream. In the existing technology, the backlight needs to be ultra-thin, which is based on the existing structure to reduce the thickness of the components used. The narrow frame of the backlight is all It is based on continuously reducing the adhesive width of the tape.
