Lokhu okusha isikrini de Apple, a isikrini yini egibele Amapaneli we-LED (Light Emitting Diode), izimbangi ezimbalwa eziqondile zenza, ubufakazi bazo buyisibonelo Dell ngubani othole i- I-Ultrasharp 2048WFP ukuthi cishe ungakholelwa ukuthi iphakeme kakhulu ekuxhumaneni nasezimpawu, kufaka phakathi intengo yayo ephansi njengekhwalithi, kepha imininingwane engavumeli ubukhulu bayo ukuthi iqhubeke nokukhula ukuqina kwayo, ngoba ngokwesilinganiso inempilo esebenzisekayo yamahora ayi-100.000 , ngakolunye uhlangothi, ukuqina kwe-fluorescence (uhlelo lokukhanyisa kabusha olusetshenziswe kuma-panels I-LCD) ngamahora ayi-12.000.
Imininingwane yokuqhathanisa ngaphakathi LED y I-LCD:
- Ngokobuchwepheshe LED I-semiconductor, okuthi lapho okwamanje idlula kuyo, ikhiphe ukukhanya, ngaphandle kokungenelela kwanoma yikuphi ukumelana, futhi akukho ukusabela kwamakhemikhali okwenzekayo okukhipha ukukhanya (i-fluorescence), ngakho-ke, njengoba ubona, asikho isici esibangela ukugqoka nokugqoka. izinyembezi ngakho-ke eyakho ukuqina ingafinyelela eminyakeni eyishumi nanhlanu noma engamashumi amabili.
- Ngakolunye uhlangothi, izikhathi zokuphendula ku- isikrini kwesinye isikhathi basenza singalungile, ngokwesibonelo, isikhathi sokuphendula se- isibonisi se-apula kungaphezu kokuphindwe kabili kwalokho kwe- Dell, kodwa kucatshangwa ukuthi ngenxa yokugqokwa kwezakhi zamakhemikhali ezidingeka ku-fluorescence eminyakeni emibili yokusetshenziswa, kungalahlekelwa ukusebenza kwayo okungu-20 kuye ku-30% futhi kubonakale ekwehleni kokuqina kwemibala nempendulo isikhathi siyanda, esikhundleni salokho isikrini ngokukhanya kwangemuva LED izimfanelo zayo zombala nesikhathi sokuphendula ngeke kushintshwe.
- Enye imininingwane okufanele ibhekwe yilokho LED ingathatha i-current ngqo kunethiwekhi, ngaleyo ndlela ikhansele enye into ye- isikrini: ukusabela okudingekayo ku-fluorescence. Imininingwane ethokozisayo ukuthi sizokonga isikhala futhi njengoba kungekho kuguqulwa kwamandla, ukulahleka kuzogwenywa, ngakho-ke isikrini LED izohlala iphakeme ngomfutho kuno isikrini I-LCD.
- Olunye uhlangothi lwemali yilokho ku izikrini LED, ikhwalithi yombala iphansi kunaleyo ye- izikrini I-LCD ezigabeni zalo zokuqala, okungukuthi, i-fluorescence ikhombisa ikhwalithi engcono yombala kune LED ngoba ayizishisi. Ngezinye izikhathi kubonakala sengathi Apple ifuna ukufihla inkinga nge-Glossy, futhi lesi yisizathu sokukhishwa kwama-euro angama-45 ku MacBook Amasentimitha angu-17 ngakunye isikrini i-anti-reflective. Lapho imibala evuthayo kudingeka izinga lokushisa elingaphansi kombala kune- LED (okuthile okufana no-3.000ºK) ukuyixazulula.
