Problems solved by technology
[0002] The homogeneity of current mobile terminals (such as mobile phones, etc.) is becoming more and more serious; especially when large-screen smart touch-screen mobile phones on the market become the mainstream, mobile phone products give consumers the impression that the difference between different products is only There is a difference between the back and the side, and the recognition is poor. Therefore, products with light-emitting rings around the fingerprint buttons have begun to appear on the market, but the brightness and uniformity are not ideal.

The invention discloses a mobile terminal, a touch screen of the mobile terminal, and a fingerprint identification module. The fingerprint identification module comprises a cover body, a fingerprint identification sensor, a luminous module and a semi-transparent film, wherein a mounting hole is formed in the cover body and comprises a main body part and a light transmission part; the light transmission part is located around the mounting hole; the main body part is light-tight; the fingerprint identification sensor is mounted in the mounting hole; the luminous module is arranged on the inner side of the cover body and used for emitting light rays to the outer side of the cover body through the light transmission part; and the semi-transparent film is arranged on the surface, close to the luminous module, of the light transmission part. The invention furthermore discloses the touch screen and a mobile terminal. Therefore, the luminous uniformity of the fingerprint identification module can be improved.
Description
technical field [0001] The invention relates to the field of electronic equipment, in particular to a mobile terminal and its touch screen and fingerprint identification module. Background technique [0002] The homogeneity of current mobile terminals (such as mobile phones, etc.) is becoming more and more serious; especially when large-screen smart touch-screen mobile phones on the market become the mainstream, mobile phone products give consumers the impression that the difference between different products is only The only difference is the difference between the back and the side, and the recognition is poor. Therefore, there are products on the market that emit light around the fingerprint button, but the brightness and uniformity are not ideal. [0003] Therefore, it is necessary to provide a mobile terminal and its touch screen and fingerprint identification module to solve the above technical problems. Contents of the invention [0004] The technical problem mainl...
