Abstract
A mobile terminal includes: a body, an organic light-emitting diode (OLED) screen component over a surface of the body, a first light sensor, and a second light sensor. The OLED screen component includes: a self-emitting light layer and a light transmitting functional layer above the self-emitting light layer; at least one optical microhole in the self-emitting light layer; the first and second light sensors are disposed under the self-emitting light layer and at positions corresponding to the optical microhole; a first polarizer and a quarter phase retarder are disposed on the first optical path; an incident light path of a ambient light to the first light sensor passes through the first polarizer and a second polarizer, and polarization directions of the first polarizer and the second polarizer are perpendicular; an incident light path of the ambient light to the second light sensor passes through the first polarizer.
