Abstract

The invention discloses a backboard of an optical display module. The optical display module comprises a display panel, a light guide plate and the backboard. The backboard comprises a light reflection coating, a substrate and a conductive anti-oxidation coating which are sequentially arranged from top to bottom, wherein the light reflection coating is arranged on the side, close to the light guide plate, of the substrate, and the conductive anti-oxidation coating is arranged on the side, away from the light guide plate, of the substrate. The invention further provides a preparation method ofthe backboard of the optical display module. The backboard integrates a light reflection function, an anti-static function, a fixing function and an anti-oxidation function, and can meet high use requirements; a multifunctional slurry coating mode is adopted in the preparation process of the backboard, so that environmental pollution is avoided, the production efficiency is high, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of optical display modules, in particular to a back plate of an optical display module and a preparation method thereof. Background technique [0002] A display backlight module generally includes components such as a display panel, a light guide plate, a reflector, and a backplane. The light guide plate converts the line light source into a surface light source, so that the light guide plate emits light evenly. The reflective sheet is arranged between the light guide plate and the back plate, and its function is to reflect the light exposed on the bottom surface of the light guide plate back into the light guide plate, so as to improve the use efficiency of light. The backplane is generally made of metal material, and functions to fix and protect the entire backlight module. [0003] In addition, in the prior art, the production process of electroplating or spraying is generally used for the backplane to ...
