Olu lutsha isikrini de iapile, yiyo isikrini yintoni ekhwela Iipaneli ze-LED (I-Light Emitting Diode), abambalwa abakhuphisana ngokuthe ngqo bayayenza, ubungqina babo ngumzekelo Dell owakhupha i I-Ultrasharp 2048 WFP Ukuthetha ngokubanzi, unokukholelwa ukuba iphezulu ekunxibelelaneni kunye neempawu, kubandakanywa nexabiso layo eliphantsi njengomgangatho, kodwa iinkcukacha ezingavumeli ukuphakama kwayo ukuba kuqhubeke nokukhula kukuqina kwayo, kuba ngokomndilili inobomi obuncedo beeyure ze-100.000. , Kwelinye icala, ukuqina kwe-fluorescence (inkqubo yokukhanyisa esetyenziswa kwiipaneli LCD) ziiyure ezingama-12.000.
Iinkcukacha zokuthelekisa phakathi I-LED y LCD:
- Ngokobuchwephesha I-LED I-semiconductor, ethi xa i-current idlula kuyo, ikhupha ukukhanya, ngaphandle kokungenelela kwanoma yikuphi ukuchasana, kwaye akukho nakuphi na ukusabela kweekhemikhali okukhupha ukukhanya (i-fluorescence), ngoko, njengoko ubona, akukho nto ebangela ukuguga kunye nokukrazula. kwaye ngoko ke ukuqina Inokufikelela kwiminyaka elishumi elinesihlanu okanye engamashumi amabini.
- Kwelinye icala, amaxesha okuphendula kwi-a isikrini Ngamanye amaxesha zisenza singalunganga, umzekelo, ixesha lokuphendula le apple screen ingaphezulu kokuphindwe kabini kuleyo ye Dell, kodwa kucingelwa ukuba ngenxa yokugqoka kunye nokukrazula kwamacandelo ekhemikhali afunekayo kwi-fluorescence kwiminyaka emibini yokusetyenziswa, inokulahlekelwa yi-20 ukuya kwi-30% yokusebenza kwayo kwaye oku kubonakaliswa kubukhulu obuphantsi bemibala kunye nexesha lokuphendula. iyanda, nangona kunjalo isikrini ngesibane esingasemva I-LED Awuyi kubona iimpawu zayo zombala okanye ixesha lokuphendula litshintshiwe.
- Enye inkcukacha ekufuneka ithathelwe ingqalelo kukuba i I-LED Bangathatha okwangoku ngokuthe ngqo kuthungelwano, ngaloo ndlela berhoxisa enye into ye isikrini: ukusabela okuyimfuneko kwi-fluorescence. Iinkcukacha ezinomdla kukuba siya kugcina indawo kwaye ekubeni kungekho kuguqulwa kwamandla, ilahleko iya kuphetshwa, ngoko ke, isikrini I-LED iyakuhlala iphezulu ngamandla kune isikrini LCD.
- Elinye icala lengqekembe kukuba kwi izikrini I-LED, umgangatho wombala ungaphantsi kunowo izikrini LCD ekuqaleni kwayo, oko kukuthi, i-fluorescence ibonisa umgangatho ongcono wemibala kunokuba I-LED ekubeni ingabatshisi. Ngamanye amaxesha kubonakala ngathi iapile ufuna ukufihla ingxaki nge-Glossy, kwaye esi sizathu sokuchitha i-euro ezingama-45 kwi these 17 intshi enye isikrini anti-reflective. Imibala evuthayo ifuna ubushushu bombala ophantsi kuno I-LED (into efana ne-3.000ºK) ukuyisombulula.
