Uma sibhekene nalokho isipoko noma isithunzi kumakhalekhukhwini wethu, akuyona yonke elahlekile futhi kunezixazululo. Lo mphumela uvame ukukhiqizwa ngokushiya isithombe esifanayo esime esikrinini isikhathi eside futhi uma singaqapheli sizokwakha lokho okwaziwa nangokuthi "umphumela wokushisa" noma "ukushisa ngaphakathi".
Ngalesi sizathu, izinkampani ezifana ne-Samsung, kumafoni abo, ikakhulukazi uma unezaziso ezisebenzayo esikrinini esibizwa nge- "Always On Display", ibashukumisela kuyo yonke indawo ukugwema lowo mphumela esizowuqaqa ukwenza ubukhona bawo bucace nokuthi ungakuphatha kanjani uma kungenzeka sinakho komakhalekhukhwini bethu.
Uyini umphumela wesipoki noma wesithunzi?
Ngokuyisisekelo sikhuluma ukuthi isipoki noma isithunzi sisebenza kuselula yethu ukuguqulwa kombala unomphela ezindaweni ezisetshenziswe kakhulu. Ngokuya ngezindawo zesikrini ezisetshenziswa njalo, amaphikseli kuzo angaqala ukonakalisa ukusetshenziswa kwempilo yakho futhi abangele lokho kushoda kombala okungasebenzi kahle kwalokhu esikrinini nakho okuqamba igama laso.
Uma ubizwa nangokuthi umphumela we "burn in", kungenxa yokuthi leyo ngxenye yesikrini ihlupheka umbala kuphaneli. Lokhu kungathatha isimo sombhalo noma ulayini owenza isithombe, noma i-gradient yombala noma amaphethini angabonakala ukuze sizibheke.
Lokhu akusho lokho isikrini sethu sizoqhubeka nokusebenza ngokufanayo, kepha ngalokho kushoda kwekhwalithi esithombeni kuleyo ndawo nalezo zithunzi. Kuma-foodies kuyinkinga enkulu futhi ezinkampanini bahlala bekugwema.
Ukuze wazi okuningi ngomlando walomphumela, sekuvele kwenzeka kubaqaphi abadala beCRT (lezo ezinkulu), lapho izinhlanganisela ze-phosphor ezikhipha ukukhanya ukukhiqiza izithombe zilahlekelwe ukukhanya kwazo ngokuhamba kwesikhathi.
Kungani ifoni yami ihlushwa umphumela "wokusha" noma umphumela wesipoki?
Isizathu sokushisa noma ukuphefumula ukuhluka kumjikelezo wempilo wezinto ezikhiqiza ukukhanya esikrinini. Njengoba "bekhula", ukukhanya kwabo kuyashintsha, bese ukukhiqizwa kabusha kombala kuyahluka ngokuhamba kwesikhathi. Kumele kuthiwe zonke izikrini zizwa lolu shintsho lombala njengoba iminyaka ihamba, yize kunezindlela zokuyivimba ukuthi ingenzeki ngaphambi kwesikhathi.
Uma siya kumaphaneli we-OLED esingabona kwamanye amamodeli, ikakhulukazi aphezulu kakhulu, i-Samsung, umphumela wesithunzi ungabonakalar njengomphumela wezikhathi ezahlukene zokuphila phakathi kwamaphikseli angaphansi we-LED obomvu, oluhlaza okotshani nokuhlaza okwesibhakabhaka. Zonke lezo zindawo lapho kunezakhi ezivame ukutholakala lapho, njengezinkinobho zokuzula noma ibha yesaziso, zivame ukuhlangabezana nale nkinga.
Lapho usebenzisa umbala ofanayo ofanayo, ngenkathi ezinye izindawo ngezikhathi ezithile zizala inani elikhulu lemibala, baguga ngaphambi kokukhiqiza lowo mphumela ongafuneki ngumsebenzisi. Uma singena kwezobuchwepheshe, inkinga ukuthi ama-LED aluhlaza okwesibhakabhaka anokusebenza okuncane kokukhanya kunamaphikseli abomvu noma aluhlaza. Ngamanye amagama, ukuze i-LED eluhlaza okwesibhakabhaka ibe nokukhanya okufana nokubomvu noma okuluhlaza, idinga amandla amaningi. Ngokuthola amandla amaningi okuzala kabusha lokho kukhanya, lokhu kusho ukuthi i-pixel yehlisa isithunzi ngaphambili nangokushesha.
Izixazululo ezingenzeka ezivela kubakhiqizi
Abakhiqizi abanjengoSamsung nezibonisi zabo ze-AMOLED banazo bengisebenzisa ukuhlelwa kwe-pentile sub-pixel ku-hardware kusuka ku-Galaxy S3. Ngamanye amagama, sekuzanywe okwehadiwe iminyaka, ngakho-ke akudingeki wenze lutho. Ngenkathi kukhona abanye abakhiqizi okuthi esimweni se-Android Wear, isistimu yokusebenza ye-Android yokugqokekayo, sebenzisa umsebenzi "Wokuvikela uBurn". Le modi ishintsha ngezikhathi ezithile okuqukethwe kwesikrini ngamaphikseli ambalwa ukusabalalisa ukukhiqizwa okulula phakathi kwabo futhi kuguga ngejubane elifanayo.
Sibuyela emuva ku ama-smartphones ane-Samsung Always On Display nokuthi ngokuzenzakalela basebenzisa lelo qhinga. Iwashi elenziwe lasebenza lishintsha ukuma ngezikhathi ezithile ukugwema lo mphumela "wokushisa" noma umthelela wethunzi.
Yini ongayenza kuselula yakho?
Lezi ziyi amanye amathiphu esiwancomayo qhubeka ukwandisa isikhathi esisebenzisekayo sesikrini sakho esiphathekayo bese uvikela umphumela wesipoki noma wesithunzi:
- Gcina ukukhanya kwesikrini sakho kuphansi. Ukwengeza ukukhanya kudinga okwengeziwe manje ngakho-ke impilo ye-LED ifinyeziwe.
- Nciphisa isikhathi esikrinini. Uma isikrini sivuliwe isikhathi eside, imfushane impilo ye-LED. Ukuyishintshela kumasekhondi ayi-15 noma angama-30 kuhle kusuka kuzilungiselelo zesikrini seselula yakho.
- Sebenzisa Imodi Yokuntywila. Le modi etholakala kwezinye izinhlobo ze-Android isivumela ukuthi sifihle ibha yesaziso, ngakho-ke izithonjana ezimile ngeke zibe khona.
- Sebenzisa ukuthinta kwesikrini okususa ibha yokuzulan: kusuka ku-Android 10 ukuthinta okusha kokuzulazula okusivumela ukuthi sisuse ibha yomumo seyivele ikhona. Eqinisweni, ku-Samsung Galaxy bangasuswa ngokuphelele kuzilungiselelo.
- Sebenzisa iphepha lodonga noma iphepha lodonga ngemibala emnyama futhi usebenzise uhlelo lokusebenza ukuyishintsha nsuku zonke.
- Sebenzisa izinhlelo zokusebenza zekhibhodi ezinikeza izingqikithi ezimnyama ukuvimbela ukonakala kombala.
- Uma usebenzisa uhlelo lokusebenza lokuphequlula iwebhu, zama ukungabi nezinto eziningi kusixhumi esibonakalayo.
Futhi sigcina ngokuthi amamodeli wamanje we-AMOLED anempilo ende kuneminyaka embalwa edlule. Yize njalo kufanele uqaphele futhi ungalokothi ushiye isithombe esimile amahora angama-24 ngosuku, izinsuku eziyi-7 ngeviki. Amanye amathiphu wokunweba impilo yalabo basebenzisi abangafuni ukushintsha iselula yabo njalo eminyakeni emibili futhi bafuna ukuwayisa ku-3 noma ku-4.
