Integrated light guide module bottom film, light guide module and bottom film processing method

Abstract

The invention discloses an integrated light guide module bottom film, a light guide module and a bottom film processing method. The bottom film comprises a substrate and a connection bar, wherein the connection bar and the substrate are arranged integrally; a conductive silver paste layer is arranged on the front surface of the substrate and the connection bar; the conductive silver paste layer is arranged corresponding to the line of a lighting circuit; the end position of the connection bar is provided with a connector; the front surface of the substrate is provided with a reflective ink layer; the pad position of the line formed by the conductive silver paste layer is not provided with the reflective ink layer; the pad position of the line formed by the conductive silver paste layer is provided with an LED; and a water adhesive layer is arranged above the reflective ink layer. Through directly arranging the line and the LED on the bottom film, a step of gluing an FPC lamp strip can be saved, mechanical production is facilitated, the material cost can be reduced, the manual cost can also be reduced, the production efficiency is improved, and the product quality can also be improved.

Description

technical field [0001] The invention discloses an integrated light guide module, in particular to a base film of the light guide module, a processing method of the light guide module and the base film. Background technique [0002] The light guide module is an indispensable accessory for mobile phones, luminous keyboards, and tablet computers. 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. 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 t...

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, the FPC light strip The processing cost is very high, and the price of the light bar itself is expensive, so that the cost of the entire light guide module is very high, and the cost is not easy to control; on the other hand, the FPC light bar needs to be manually bonded to the light guide The groups are pasted together, because the LED lights on the FPC light bar have to be aligned with the holes on the light guide module when pasting, so it is time-consuming and labor-intensive when pasting, the labor cost remains high, and the production efficiency is low
