Problems solved by technology

However, when the existing light guide substrate is installed on the back of the button, the edge section is not sealed with light. After the light from the section of the light guide plate diverges, it is easy to leak out through the gap of the button, which reduces the utilization rate of light and affects the appearance of the product.

Abstract

The invention discloses a light guide key module used for a keyboard of electronic products, the light guide key module comprises a light guide plate, a glue layer and a metal thin film layer, the bottom surface of the light guide plate is attached to the top surface of the glue layer, and the bottom surface of the glue layer is attached to the metal thin film layer. The light guide key module ischaracterized by further comprising a light tight ink layer covering a lateral surface of the light guide plate. The light guide key module disclosed by the invention is additionally provided with the light tight ink for covering the lateral surface of the light guide plate, thereby avoiding light leakage from an edge of the light guide plate and achieving good light tight effect.

Description

technical field [0001] The invention relates to accessories of electronic products, in particular to a light guide button module used for keyboards of electronic products. Background technique [0002] With the development of science and technology, electronic products appear more and more frequently in people's lives, and have even become an indispensable part of people's lives. In general, electronic products (such as mobile phones, LEDs, MP3 or MP4, etc.) are often equipped with a light source on the inner side of the button to illuminate the button, so that users can still find the logo on the button when using it in the dark to make a correct choice. button. At present, one kind of light source is to install several LED lights inside the button to illuminate. However, the structure of this lighting method is relatively complicated, and the light distribution is uneven. The area near the LED light is brighter, while the area far away from the LED light Relatively dark,...
