A system comprising a display and an ambient light sensing module, the ambient light sensing module being located beneath the display. The display comprises an array of light emitting diodes and a first polarizer located above the display. The sensing module comprises a first sensor and a second sensor, a second polarizer being located above the second sensor.

Ambient light sensing

A method for estimating ambient light at a display screen of a device. The method comprises determining one or more expected colour values of display screen output light, detecting light with a sensor positioned behind the display screen, determining one or more colour values of the detected light, determining a difference between the one or more expected colour values of the display screen output light and the one or more colour values of the detected light, and, from the determined difference, estimating a first portion of the detected light corresponding to the display screen output light and a second portion of the detected light corresponding to ambient light.

Method and device for estimating ambient light

The arrangement comprises a filter region () filtering electromagnetic radiation and a shielding component () inhibiting propagation of electromagnetic radiation. The filter region comprises a central filter region () and a separate peripheral filter region (). The shielding component comprises an aperture (). The aperture is arranged above the central filter region. The central filter region and the peripheral filter region are optimized for different angles of incidence (&#x3b1;, &#x3b2;) and provided for measurements by individual sensor regions ().
