Input device and light conducting plate thereof

Abstract

The invention provides an input device and a light guide plate thereof; the light guide plate is provided with light transmission and application to the input device; one surface of the light guide plate comprises a first area and a second area; the first area is covered by lighttight material; if the light beam is emitted in the light guide plate, the light beam can emit out through the second area; the input device and the light guide plate thereof can greatly simplify the complex structure and the preparation process of the traditional luminescence keyboard and can effectively improve the light guiding efficiency of the light guide plate.

Description

technical field [0001] The invention relates to an input device and its light guide plate, in particular to a keyboard with light emitting function and its light guide plate. Background technique [0002] With the continuous evolution of science and technology, information equipment is also becoming more and more popular. Take the most commonly used computer as an example, there are not only various brands and styles on the market, but its tentacles extend to homes, factories, offices and schools. And other places, its level of use has even spread to all walks of life, and it has almost become people's daily necessities. Conventional computers, including desktop computers and notebook computers, mostly need to be equipped with a keyboard for users to perform operations such as character input. [0003] A kind of luminous keyboard quite popular on the market at present, because it has the luminous function that traditional keyboard lacks, therefore, can attract the attention...

AI Technical Summary

Problems solved by technology

[0006] However, since the shielding layer 145 and the reflective layer 144 must be provided above and below the light guide plate 143, it not only increases the complexity of the manufacturing process of the luminous keyboard 1, but also reduces the production efficiency, and also increases the production cost of the luminous keyboard 1.

In addition, the light entering the light guide plate 143 may also exit from the side of the light guide plate 143, which will reduce the light intensity provided to the luminous keyboard 1.
