1. A mobile terminal, comprising:
a display panel;
a first polarizing component arranged on a first side of the display panel; and
a light sensor arranged on an opposing second side of the display panel that is configured to receive ambient light and light emitted by the display panel, the ambient light being incident onto the light sensor after passing through the first polarizing component and the display panel, and the ambient light being linear polarized light having passed through the first polarizing component, the light sensor including N first regions and M second regions, where a total area of the N first regions is equal to that of the M second regions, and N and M are natural numbers, wherein:
each of the first regions includes a second polarizing component and K photodetectors arranged in an array, where the second polarizing component is located above the K photodetectors, and a polarization direction of the second polarizing component is parallel to that of the first polarizing component; and
each of the second regions includes a third polarizing component and L photodetectors arranged in an array, where the third polarizing component is located above the L photodetectors, K and L are natural numbers, and a polarization direction of the third polarizing component is perpendicular to that of the second polarizing component.
