Abstract

The invention discloses an optical module and a mobile terminal, the optical module comprises a collimator, a photosensitive unit and a wiring structure, the photosensitive unit is arranged on the surface of one side of the collimator, and the wiring structure is arranged on the surface of the side, deviating from the collimator, of the photosensitive unit. The photosensitive unit and the wiring structure are directly formed on the surface of one side of the collimator. Therefore, the photosensitive unit and the wiring structure do not need to be bonded with the collimator through an adhesive,and a bearing substrate does not need to be added for forming the photosensitive unit and the wiring structure, so that the thickness of the whole optical module is reduced, and the occupied space ofthe optical module is smaller. Meanwhile, after the adhesive between the photosensitive unit and the collimator and the adhesive between the wiring structure and the collimator are omitted, the distance between the photosensitive unit and the display screen of the mobile terminal and the distance between the wiring structure and the display screen of the mobile terminal are smaller, so that the signal strength is higher, and the photosensitive efficiency of the optical module is higher.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optical module and a mobile terminal. Background technique [0002] Optical modules such as fingerprint modules are one of the core components of mobile terminals. With the continuous development of the mobile terminal industry, people have higher and higher performance requirements for optical modules, which brings comparisons to the structural design of optical modules. big challenge. [0003] Taking the fingerprint module as an example, a traditional fingerprint module usually includes a carrier substrate, a photosensitive unit, a wiring structure and a collimator. Both the photosensitive unit and the wiring structure are arranged on the side of the carrier substrate facing the collimator, and the collimator is located Between the display screen and photosensitive unit. When the user puts his finger on the fingerprint sensing area, the light is reflected by the user...
