Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] An embodiment of the present invention provides a reflection sheet 20, such as figure 2 As shown, it includes a base layer 21 , a reflective layer 22 disposed on the base layer 21 , and a flatness adjustment layer 23 disposed below the base layer 21 ; the flatness adjustment layer 23 is used to keep the surface close to the base layer 21 flat.

[0031] Wherein, the reflective layer 22 can be directly coated on the base layer 21 through a coating proces...

Abstract

An embodiment of the invention provides a reflector plate, a backlight module and a display device. The reflector plate comprises a base layer, a reflecting layer and a flatness adjusting layer. The reflecting layer is arranged on the base layer, and the flatness adjusting layer is arranged under the base layer; the flatness adjusting layer is used for keeping the surface, which is close to the base layer, of the flatness adjusting layer flat. The reflector plate, the backlight module and the display device have the advantage that the problem of white spot defects due to the fact that an existing reflector plate rubs with optical net points of light guide plates can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflective sheet, a backlight module and a display device. Background technique [0002] The backlight module provides a light source for a Liquid Crystal Display (LCD for short), and is an important component of the LCD. As a key diaphragm in the backlight module, the reflector is mainly used to reflect light and increase the output light of the backlight module. [0003] In the backlight module manufacturing process, such as figure 1 As shown, the stamping of the back plate 10 usually has a local C-convexity ( figure 1 (shown by the dotted line in the middle), so that after the backlight module is manufactured, the reflective sheet 20 will squeeze the light guide plate 30 along with the protruding position of the back plate 10, resulting in the friction of the light guide plate 30 during vibration and high temperature and high humidity tests. The optical dots will wear ou...
