Light guide structure of touch key and mobile terminal

Abstract

The embodiment of the invention provides a light guide structure of a touch key, which is applied to a mobile terminal with a touch screen. The touch screen is provided with a character region, and comprises an upper light reflecting piece, a lower light reflecting piece and a light source assembly, wherein the upper light reflecting piece is provided with a light outlet hole which is arranged corresponding to the character region of the touch screen, the upper light reflecting piece and the lower light reflecting piece are oppositely arranged so as to form a transmission cavity of light, the transmission cavity is internally provided with a light guide film used for transmitting the light to the light outlet hole, the light guide film is provided with al light guide column, and the light guide column is arranged on a light path of the light source assembly for emitting light to the light guide film. The invention further provides a mobile terminal which comprises the light guide structure of the touch key. In the light guide structure, the light guide column is arranged on the light guide film, thereby enabling the structure to be simpler, and being conducive to manufacturing; and a light guide column with the thickness being small can be adopted so as to reduce the thickness of the mobile terminal and be conducive to thinning of the mobile terminal. Meanwhile, installation of the light guide column does not require an installation hole on a shell, so that the structural strength of a product is high.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a light guide structure of a touch key and a mobile terminal. Background technique [0002] At present, with the development of electronic equipment technology, mobile terminals (such as smart phones, tablet computers, etc.) tend to be thinner. In the prior art, mobile terminals generally include light guide structures with touch keys, such as figure 1 As shown, the light guide structure generally includes an LED lamp 101, a lower reflective sheet 102, a light guide column 103, a light guide film 104, an upper reflective sheet 105, and a touch screen 106 from bottom to top, and the touch screen 106 is provided with a character area of ​​a touch key 107 , a touch key 108 is set on the character area 107 , and a dot structure 109 is set on the character area 107 corresponding to the touch key on the light guide film 104 . When in use, the light emitted by the LED lamp passes t...
