Self-cleaning diaphragm for backlight module, backlight module and manufacturing method

Abstract

The invention provides a self-cleaning diaphragm for a backlight module, which comprises a diaphragm base material and further comprises a diffusion layer formed on one side of the diaphragm base material, and the diffusion layer comprises a plurality of micro bulges which are dispersedly distributed on the surface of the diaphragm base material and micro convex tops which are dispersedly distributed along the parts, protruding out of the surface of the diaphragm base material, of the micro bulges. The invention provides a backlight module which comprises the self-cleaning diaphragm. The invention further provides a manufacturing method of the self-cleaning diaphragm for the backlight module. The diffusion layer formed on the surface of the diaphragm base material comprises the micro protrusions and the micro convex tops, when foreign matter adheres to the surface of the diffusion layer, due to the fact that the surface structure and roughness are both in the micron order, dust and other foreign matter cannot be adsorbed to the surface and can roll along the surface, and self-cleaning is achieved; compared with a traditional contact type cleaning mode through a dust sticking rod, the self-cleaning mode can effectively avoid the bad problems of membrane pollution, wrinkles and the like, and the membrane yield and the assembling efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of LCD backlights, in particular to a self-cleaning film used for a backlight module, a backlight module and a manufacturing method. Background technique [0002] With the rapid development of LCD display technology, the backlight module of LCD display products is indispensable for yield monitoring during the production and assembly process. During the assembly process of the diaphragm, the cleaning of the diaphragm is also essential. During the transfer process, it is also easy to cause problems such as contamination of the diaphragm, dirt, and high dependence on personnel. At the same time, there is a problem of large workload of personnel assembly. Existing diaphragm cleaning has caused great economic losses to the assembly plant and end customers. During the current assembly process, the production line uses sticky dust sticks to improve the foreign matter of the production line diaphragm, but it is stil...

[0002] With the rapid development of LCD display technology, the backlight module of LCD display products is essential for yield monitoring during the production and assembly process. During the assembly process of the diaphragm, the cleaning of the diaphragm is also essential. In the module During the transfer process, it is also easy to cause problems such as membrane pollution, dirt, and high dependence on personnel, and there is also the problem of large workload of personnel assembly

The existing diaphragm cleaning has caused great economic losses to the assembly factory and end customers. During the current assembly process, the production line uses sticky dust sticks to improve the foreign matter of the diaphragm on the production line, but it is still necessary to contact the film during the process of cleaning foreign matter. If the membrane is damaged, it will cause other non-repairable problems, such as membrane pollution, membrane wrinkles and other defects, resulting in scrapped membranes and low assembly efficiency
