Isibuko esibuyela emuva esilwa nokukhanya ngokuvamile sifakwa enqoleni. Siqukethe isibuko esikhethekile nama-diode amabili azwela ukukhanya kanye nesilawuli se-elekthronikhi. Isilawuli se-elekthronikhi sithola ukukhanya okuya phambili kanye nesignali yokukhanya kwangemuva ethunyelwa yi-diode ezwela ukukhanya. Uma ukukhanya okukhanyisiwe kukhanya esibukweni sangaphakathi, uma ukukhanya kwangemuva kukhulu kunokukhanya kwangaphambili, isilawuli se-elekthronikhi sizokhipha i-voltage engqimbeni eqhubayo. I-voltage esengqimbeni eqhubayo ishintsha umbala wesendlalelo se-electrochemical sesibuko. Uma i-voltage iphakeme, kulapho umbala wesendlalelo se-electrochemical uba mnyama khona. Ngalesi sikhathi, noma ngabe ukukhanya kwesibuko esibuyela emuva kunamandla, i-anti-glare ngaphakathi kwesibuko esibuyela emuva eboniswa emehlweni omshayeli izobonisa ukukhanya okumnyama, hhayi okukhazimulayo.
