## Abstract

This application provides a mobile terminal and relates to the field of display technologies. The mobile terminal includes a display panel, a cover body, a photoelectric conversion apparatus, and a bearer layer. The bearer layer includes a non-polarized part, where the bearer layer is disposed between the cover body and the display panel, and the bearer layer is located in a partial transmissive region of the display region, where an orthographic projection of the photoelectric conversion apparatus on the bearer layer is located in an orthographic projection of the non-polarized part on the bearer layer, and the non-polarized part is configured to enable a polarization direction of light. Furthermore, the mobile terminal includes an ink layer, disposed on a surface of the bearer layer, where the ink layer is located in a peripheral region of the mobile terminal. As discussed herein, the techniques resolve a problem of how to evenly print ink in a corresponding peripheral region of the mobile terminal.
