MOBILE TERMINAL Russian patent published in 2020 - IPC H01L27/32 

FIELD: physics.

SUBSTANCE: invention relates to mobile terminals. Mobile terminal comprises the following components: housing, OLED screen component 11, first light sensor 12 and second light sensor 13; OLED screen component 11 is located on the housing surface, wherein OLED screen component 11 comprises the following components: a layer of self-radiation of light 111 and a transmissive functional layer 112 above a layer of self-radiation of light 111; in the light self-radiation layer 111, at least one optical microhole 113 is formed; first light sensor 12 and second light sensor 13 are under a layer of self-radiation of light 111 in positions corresponding to optical micro-hole 113; wherein first polarizer 14 and quarter-wave phase plate 15 are in first optical path; path of incident ambient light to first light sensor passes through first and second polarisers 16 with perpendicular polarization directions; path of incident ambient light to second light sensor 13 passes through first polariser 14.

EFFECT: higher accuracy of measuring ambient light intensity using a light sensor.
