Title:
LIGHT GUIDE STRUCTURE, CASING, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/200992
Kind Code:
A1
Abstract:
A light guide structure (3), comprising: a transparent decorative member (31) and a light guide film (32) attached together. A protruding light entrance (R1) is provided on a surface (F0) of the light guide film (32) not attached to the transparent decorative member (31). The protruding light entrance (R1) is used for guiding light emitted by a light-emitting source (4), so that the light, after entering at the protruding light entrance (R1), passes through regions of the light guide film (32) other than the protruding light entrance (R1) and is transmitted to the transparent decorative member (31), and then exits from the transparent decorative member (31). In the present invention of the light guide structure (3), a casing (1) and an electronic device (100), the light guide structure (3) is disposed on a frame (2) of the casing (1) such that the light emitted by the light-emitting source (4) is guided to exit from the light guide structure (3) on the frame (2), thereby freeing front-screen space and effectively increasing the screen-to-body ratio. In addition, the light, after entering at the protruding light entrance (R1), gradually attenuates as it is transmitted to the regions of the light guide film (32) other than the protruding light entrance (R1), thereby producing a gradual change in brightness and improving display illumination.
