Multi-layer color light guide structure, its using method and key module with this structure

Abstract

A keypad module with a multilayered color light guide structure includes a keypad structure, a light guide structure arranged inside the keypad structure, a plurality of shading plates and the shading plates arranged inside the keypad structure and corresponding with the light guide structure. The light guide structure consists of a plurality of light guide plates, at least one light guide belt formed on the position of the each light plate corresponding with the keypad. The light guide belts are staggered with each other or overlapped correspondingly and have different color layers. When an electric device controls the lighting components one by one or selectively to light, each layer of the light guide belts generates lights with different color light or mixed color light which is refracted to the keypad group of the keypad structure. And the keypads of the keypad structure can generate the light transmission effect with different color light and display the figures and the graphs on the keypad surface.

Description

technical field [0001] The invention relates to a light guide plate, in particular to a multi-color light guide plate structure. Background technique [0002] With the progress and development of science and technology, portable electronic products such as mobile phones, personal digital assistants, etc., have become necessary information products for modern people. These electronic products all have button structures, which allow users to input data, Or perform various functions of the electronic product. [0003] In addition, the key structure of each electronic product has a backlight, and the backlight allows the user to clearly operate the key under the illumination without light source, so as to prevent the user from pressing the wrong key. In the past, the backlight inside the button structure was a transparent and colorless light guide plate. After the light-emitting diode inside the electronic product was lit, when the light was guided by the light guide plate, the...

Problems solved by technology

For example, when using a mobile phone to take pictures, play games or watch videos, the backlight inside the mobile phone makes the numbers and patterns on the surface of all the buttons produce a light-transmitting effect, making it difficult for the user to distinguish which button groups are used to control the game , camera or video playback operations, so that users often press the wrong button

Even, when some mobile phones are taking pictures, playing games or watching videos, the mobile phone must be turned to use. When the lighting effect is used, it makes it difficult for the user to distinguish which key groups are used to control the operation of playing games, taking photos or playing videos.
