Flexible printing patch panel, input module and portable device

Abstract

The invention provides a flexible printing patch panel, an input module comprising the flexible printing patch panel and a portable device comprising the input module, the flexible patch panel is composed of positive and negative of conductive pattern covered with insulation layer, in the insulation layer is disposed with: a light guide part for guiding light from light source into the insulationlayer; and a light emitting part for emitting light guided from the light guide part from inside the insulation layer to outside the layer, which can implement reduction of parts number and panel bonding operation, meanwhile, can implement improvement of press buttom sense, good illumination proceeded on the press button input operation part, and further slimming of obtained module or device.

Description

technical field [0001] The present invention relates to a flexible printed wiring board, an input module having the flexible printed wiring board, and a portable device having the module. Background technique [0002] In portable devices such as mobile phones, notebook computers, and digital cameras, an input module is usually used to complete required input operations. Furthermore, in the above-mentioned input module, a flexible printed wiring board is used as part of its structure, and fixed contacts for switching are provided on conductive patterns so as to perform switching operations in accordance with input operations. [0003] In addition, in the above-mentioned portable devices such as mobile phones, there is a key input operation panel with input keys, and in many cases, the input keys and the like are illuminated to facilitate key input operations through the key input operation panel. [0004] As a conventional technique for making input keys and the like of a ke...

Problems solved by technology

Therefore, there are problems that the light cannot be guided far away, and a large number of LEDs (light sources) are required, and the lighting is easy to be scattered, and the desired position cannot be illuminated emphatically, etc.

[0010] In addition, in the prior art disclosed in Japanese Patent Application Publication No. 9-55143 and Japanese Publication No. 2005-268165, although the number of light sources is reduced by setting a light guide plate, thinning and cost reduction are realized. The light board is installed separately from the key board and flexible printed wiring board, so there are problems such as a decrease in the key feel and an increase in the bonding process for bonding various boards, etc.
