Problems solved by technology

At present, in the button modules of handheld devices, light guide films made of polyester (polyester, PET) or polycarbonate (polycarbonate, PC) are often seen. However, the optical properties of polyester or polycarbonate light guide films The luminance is poor. If you want to provide better optical luminance, you must increase the thickness of the light guide film. In this way, it may lead to poor pressure sensitivity of the keys

Embodiment Construction

[0015] Certain terms are used in the specification and following claims to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may use different terms to refer to the same element. This description and the subsequent claims do not use the difference in name as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned throughout the specification and the following claims is an open term, so it should be interpreted as "including but not limited to".

[0016] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the button module 100 of the present invention. Such as figure 1 As shown, the button module 100 includes a circuit board 110, a plurality of buttons 120-1, 120-2, 120-3, a plurality of elastic structures 130-1, 130-2, 130-3, and a plurality of light emitting elements 140 and a light guide ...

Abstract

The invention discloses a key-press module group for handheld devices such as mobile phones, comprising a circuit board, at least one key-press, at least one luminous element and a light guide film. The key-press is arranged on the circuit board; the luminous element is coupled on the circuit board to provide a light source; the light guide film is arranged between the circuit board and the key-press to guide the light source provided by the luminous element to the key-press, wherein the material of the light guide film is a flexible light guide material, such as silicon-oxygen compound. The light guide film made from flexible light guide material such as a silicon-oxygen compound light guide film has good luminance value, and soft characteristic thereof can provide good pressure sense of the key-press.

Description

technical field [0001] The present invention relates to a button module, in particular to a button module including a light-guiding film made of flexible light-guiding material. Background technique [0002] The light guide film is an important component in the button module, which is used to guide the light emitted by the light-emitting elements in the button module to the surface of the button. At present, in the button modules of handheld devices, light guide films made of polyester (polyester, PET) or polycarbonate (polycarbonate, PC) are often seen. However, the optical properties of polyester or polycarbonate light guide films The luminance is poor. If better optical luminance is to be provided, the thickness of the light guide film must be increased, which may lead to poor pressure sensitivity of the keys. Contents of the invention [0003] Therefore, one of the objectives of the present invention is to provide a key module with a flexible light-guiding material (f...
