Non-rectangular display backlight module and manufacturing method

Abstract

The invention provides a non-rectangular display backlight module and a manufacturing method, the non-rectangular display backlight module comprises LED light sources, a light guide plate and a reflector, the LED light sources are electrically connected with an FPC circuit board, a diffusion film and a light enhancement plate are arranged in front of the light guide plate, and the LED light sources are arranged around the light guide plate in a non-rectangular manner for display; the non-rectangular light guide plate and the LED light source are welded and fixed on the FPC flexible circuit board, a plurality of rectangular optical lattice points are arranged on the light guide plate, and local optical processing is performed, so that the LED light source is led out, the diffusion film and the light enhancement plate are mounted in front of the light guide plate, the whole LED light source is fastened and fixedly assembled by the rubber frame, the LED leading-out luminous efficiency is high, and the production efficiency is high.

Description

Technical field [0001] The present invention relates to the field of backlight techniques, and more particularly to a non-rectangular display backlight module and a manufacturing method. Background technique [0002] Since modern times, most of the original car backlight shapes and display areas are rectangular, limited to the car, carrying backlight, for the automotive interior design, the shape layout design of the display area of ​​the central console and instrumentation Limited, it is impossible to achieve a beautiful cool effect. The production process is troublesome, and the light guide effect is not good. [0003] There is also a conventional technical solution to change the rectangular display view region as a circular view area, and the shape is also synchronized as a circular shape. The light guide plate of the backlight is circular, and the optical LED is arranged around the light-emitting plate ring, and the optical effect of the circular light guide plate is very dif...

AI Technical Summary

Problems solved by technology

The light guide plate of the backlight is circular, and the light incident LEDs are arranged in a ring around the light guide plate. The optical effect of the circular light guide plate is very different from that of the rectangular light guide plate with side light input, so the production methods are different, and the production is troublesome. The light guide optical effect of the rectangular backlight module, the installation and production efficiency is low, and the cost is high
