Key light guide structure and mobile phone

Abstract

The invention provides a key light guide structure and a mobile phone. The key light guide structure according to the invention comprises a light guide plate, the light guide plate comprises an illumination area for receiving illumination, a conduction area for conducting the illumination and a display area for displaying the illumination, and the key light guide structure further comprises a first light shielding piece and a second light shielding piece; the first light shielding piece is located at the upper part of the light guide plate and is covered on the illumination area and the conduction area of the light guide plate; and the second light shielding piece is located at the lower part of the light guide plate and is covered on the conduction area and the display area of the light guide plate. According to the key light guide structure provided by the invention, the light shielding pieces are arranged at the upper part and the lower part of the light guide plate to effectively avoid light leakage in a conduction process of the light guide plate, perfect the light guide distance of the light guide plate, improve the conduction efficiency of the light guide plate and reduce the interference of light leakage on mobile phone elements.

Description

technical field [0001] The invention relates to the field of mobile phones, in particular to a key light guide structure and a mobile phone. Background technique [0002] In the existing technology, such as Figure 5 and Figure 6 As shown, the button light guide structure generally has only one layer of light guide sheet, and the light guide sheet is generally in the shape of a regular strip. This light guide structure is easy to leak light, causing interference to mobile phone components, and the light guide distance is short and the efficiency is low. Contents of the invention [0003] The invention aims to provide a button light guide structure and a mobile phone with improved light guide distance. [0004] In order to solve the above problems, the present invention provides a key light guide structure, including a light guide sheet. The light guide sheet includes an illumination area for receiving light, a conduction area for transmitting light, and a display area fo...
