Abstract
A mobile terminal including a display panel, a light sensor, and a first polarizing component. The display panel is between the first polarizing component and the light sensor. The ambient light having passed through the first polarizing component is linear polarized light. The light sensor includes N first regions and M second regions, the total area of the N first regions is equal to that of the M second regions. Each of the first regions includes a second polarizing component and K photodetectors. The second polarizing component is located above the K photodetectors. Each of the second regions includes a third polarizing component and L photodetectors. The third polarizing component is located above the L photodetectors. The polarization direction of the second polarizing component is parallel to that of the first polarizing component. The polarization direction of the second polarizing component is perpendicular to that of the third polarizing component.
