Problems solved by technology

The structure of the light guide module usually includes a base film (also known as a reflective film), a light guide film, a light-shielding film and an FPC lamp strip. The base film, the light guide film and the light-shielding film are installed together to form a light guide module. The strip is mounted on the outside of the light guide module to provide the light source for the light guide module. This structure requires the FPC light strip to be very long, which is approximately equal to the length of the entire light guide module. On the one hand, th

Abstract

The invention proposes a split-type light guide module bottom film, a light guide module and a bottom film processing method, comprising: connecting a FPC with a base material; arranging a conductive silver paste layer on the front face of the base material wherein the conductive silver paste layer is arranged corresponding to the illumination circuit; arranging a FPC bonding pad on the base material corresponding to the installation position in connection with the FPC; arranging an LED welding plate on the base material corresponding to the installation position of the LED; connecting one end of the FPC to be fixedly installed at the FPC welding plate position on the base material; arranging a connection gold finger at the end position in connection with the other end of the FPC; arranging a light-reflection oil-ink layer on the front face of the base material but not at the positions of the FPC welding plate and the LED welding plate formed by the conductive silver paste layer because the conductive silver paste layer formed circuit's LED welding plate position is mounted with the LED. A water glue layer is arranged above the light-reflection oil-ink layer. With the method of the invention, not only can the material cost be reduced, but also the manual cost is cut. However, the production efficiency is increased, and the product quality is increased.

Description

technical field [0001] The invention discloses a light guide module, in particular to a split-type light guide module bottom film, a light guide module and a processing method for the bottom film. Background technique [0002] The light guide module is an indispensable accessory for mobile phones, luminous keyboards, tablet computers, etc. It can provide backlight for the display screens of mobile phones, tablet computers, etc., and can also provide backlight for luminous keyboards. The structure of the light guide module usually includes a base film (also known as a reflective film), a light guide film, a light-shielding film and an FPC lamp strip. The base film, the light guide film and the light-shielding film are installed together to form a light guide module. FPC lights The strip is mounted on the outside of the light guide module to provide the light source for the light guide module. This structure requires the FPC light strip to be very long, which is approximately ...
