Abstract

Zadatak ovog završnog rada je utvrditi utječe li, i u kojoj mjeri pozadinsko osvjetljenje na gamut IPS LCD ekrana laptopa. Spektroradiometrom će se izmjeriti spektralno zračenje ekrana pri vrijednostima 0%, 25%, 50%, 75% i 100% a rezultat će biti prikazan L, a i b vrijednostima te popratnim grafikonima. Boje koje se mjere generirane su web skriptom kojoj određujemo korak kojim će definirati boje u RGB sustavu te duljinu trajanja pojedine boje na ekranu. Ispitivanje se odvijalo u zamračenoj prostoriji kako bi se umanjili vanjske utjecaje na rezultate mjerenja. Uređaji korišteni pri mjerenju su spektroradiometar Konica Minolta CS - 200, ispitivani laptop te još jedno računalo koje je služilo za daljinsko upravljanje spektroradiometrom kako se on ne bi pomaknuo sa svog postolja. Dobiveni rezultati obrađivali su se u programu Excel, gdje se računala kolorimetrijska razlika između dva stadija osvjetljenja. Grafikoni su iscrtani pomoću programa Origin 8.

Abstract in english:	The goal of this paper is to determine whether and to what extent the background illumination of the IPS LCD screen affects its gamut. Spectroradiometer will be used to measure the spectral radiation of the screen at 0%, 25%, 50%, 75% and 100%, and the result will be represented by L, a and b values and the accompanying graphs. Measured colors are generated by a web script that sets the step for defining the colors in the RGB system and the duration of a particular color on the screen. Testing took place in a darkened room to reduce external influences on measurement results. The devices used in the measurement were the spectroradiometer Konica Minolta CS - 200, a tested laptop and another computer that was used to remote control of the spectroradiometer so it wouldn't move it from its standpoint. The obtained results were processed in Excel, where colorimetric difference between the two stages of illumination is calculated. Graphs are plotted with Origin 8.
