Abstract

The invention applies to the light guide plate field, and provides a method for preparing micron and nanometer structures on a PS (polystyrene) light guide plate. The method for preparing the micron and nanometer structures on the PS light guide plate includes following steps: using a computer to design a plane projection drawing of the micron and nanometer structures, and using an ink jet printer to print the plane projection drawing of the micron and nanometer structures on copper foil; etching the copper foil with the plane projection drawing of the micron and nanometer structures printed in ferric chloride etchant so as to obtain a copper foil model, and dipping the copper foil model in a mixed solvent which contains acetone and ethyl alcohol; sequentially electroplating the copper foil model after being dipped with a chrome metal layer and a nickel metal layer so as to obtain a work template with the micron and nanometer structures; using hot press treatment to press the micron and nanometer structures of the work template into the surface of the PS light guide plate, wherein accuracy of the ink jet printer ranges from 1000dpi (dots per inch) to 3000dpi, and the ink jet printer uses waterproof printing ink to print. The method for preparing the micron and nanometer structures on the PS light guide plate has the advantages of being low in cost, high in production efficiency, environmentally friendly, and good in durability and scuff resistance of the micron and nanometer structures.

Description

technical field [0001] The invention belongs to the field of light guide plates, in particular to a method for preparing micro-nano structures on PS light guide plates. Background technique [0002] In recent years, with the colorization and enlargement of liquid crystal displays, their application fields are more extensive, such as notebook computers, various desktop computers and LCD TVs, etc. Since liquid crystal itself cannot emit light, it is necessary to use a light source system as a light source for liquid crystal displays , such as the backlight module, wherein the light guide plate is an important component in the backlight module, mainly used to guide the transmission direction of the light beam emitted from the light source, and transform the line light source or point light source into a surface light source. [0003] In order to improve the uniformity of light emission, a plurality of dots, micro-lattice patterns or micro-nano structures are generally arranged ...
