Ingabe Ukushisa-Kungenzeka Kube Ngama-Monitor LCD?
Enye yezinkinga ezindala ze-CRT (cathode ray tube) abaqaphi ngokuhamba kwesikhathi kwakuyisimo esibizwa ngokuthi ukushisa. Lokhu kuholele ekushicileleni kwesithombe esibukweni esasihlala njalo. Lokhu kuyinto ongayibona ikakhulukazi emakhandeni omdala we-arcade afana ne- Pac-Man . Kubangelwa ukuboniswa okuqhubekayo kwesithombe esithile esibukweni isikhathi esibekiwe. Lokhu kungabangela ukuphazamiseka kwamaphosphors ku-CRT futhi kuzoholela ekutheni isithombe sishiswe esibukweni, ngakho-ke leli gama liyashisa.
Abaqaphi be-LCD basebenzisa indlela ehluke kakhulu yokukhiqiza isithombe esibukweni futhi kufanele bavikeleke kulokhu kusha. Kunokuba i-phosphors isetshenziselwe ukudala ukukhanya nombala, i-LCD inokukhanya okumhlophe ngemuva kwesikrini bese isebenzisa ama-polarizers nama-crystals ukuhlunga ukukhanya kumbala othize. Ngenkathi ama-LCD angenakukwazi ukushisa-ngendlela efanayo ababheki be-CRT, bahlupheka ngalokho abakhiqizi abathanda ukubiza ukuphikelela komfanekiso.
Kuyini ukuphikelela kwesithombe?
Njenge-burn-in ku- CRTs , ukuphikelela kwesithombe kuma-monitor e-LCD kubangelwa ukuboniswa okuqhubekayo kwamahluzo e-static esikrinini isikhathi eside. Lokhu okukwenza kubangelwa ukuthi amakristalu e-LCD abe nenkumbulo yendawo yawo ukuze akhiqize imibala yalowo mdwebo. Uma umbala ohlukile uboniswa kuleso ndawo, umbala uzosuka kulokho okumele ube khona futhi esikhundleni salokho ube nesithombe esiphelile salokho okwakuboniswe ngaphambilini.
Ukuphikelela kungumphumela wendlela ama-crystals ekubukeni abasebenza ngayo. Ngokuyinhloko, amakristalu asuka esimweni esivumela ukuthi konke ukukhanya kudlulele kolunye okuvumela noma yini. Cishe kufane ne-shutter efasiteleni. Uma isikrini sibonisa isithombe isikhathi eside kakhulu, amakristalu angathanda ukushintsha endaweni ethile, efana ne-window shutter. Kungase kushintshwe kancane ukushintsha umbala kodwa kungabangela ukuthi kuhambisane nesimo esibuzwa ngaso.
Le nkinga ivame kakhulu ezakhiweni zokubonisa ezingashintshi. Ngakho izinto ezingase zenze isithombe esiphikisanayo ibha yomsebenzi, izithombe zedeskithophu, ngisho nemifanekiso yasemuva. Zonke lezi zivame ukuba zikhona endaweni yazo futhi zizoboniswa esikrinini isikhathi eside. Uma nje ezinye ihluzo zilayishwa ngalezi zindawo, kungase kwenzeke ukubona uhlaka oluphelile noma isithombe sesithombe esedlule.
Ingabe Lihlala Phakade?
Ezimweni eziningi, cha. Ama-crystals anesimo semvelo futhi angashintsha kuye ngokuthi inani lamanje elisetshenziselwa ukukhiqiza umbala oyifunayo. Uma nje le mibala ingashintsha ngezikhathi ezithile, amakristalu kulelo pixel kufanele aguquke ngokwanele kangangokuthi isithombe ngeke sishicilelwe unomphela emakristini. Uma usho lokhu, kungenzeka ukuthi amakristalu angathola inkumbulo engapheli uma isithombe seskrini singashintshi nhlobo futhi isikrini sishiywa ngaso sonke isikhathi. Akunakwenzeka ukuthi umthengi enze lokhu kwenzeke ngoba kungenzeka ukuthi kwenzeke ekubonisweni okuhleliwe njengalabo abonakala njengamabhodi okubonisa amabhizinisi angashintshi.
Kungabe Kungavinjelwa Noma Kuqondiswe?
Yebo, ukuphikelela kwesithombe kuzikrini ze-LCD kungalungiswa ezimweni eziningi futhi kuvinjelwe kalula. Ukuvimbela ukuphikelela komfanekiso kungenziwa ngezinye zezindlela ezilandelayo:
- Setha isibuko ukuvala ngemuva kwemizuzu embalwa yesikhala esingenalutho esikrinini ngaphansi kwesiboniso kanye nezintandokazi zeskrini ohlelweni lokusebenza. Ukuvula ukukhanya kwe-monitor kuzovimbela isithombe ukuthi sikhonjiswe esikrinini isikhathi eside. Yiqiniso, lokhu kungacasula kwabanye abantu njengoba isikrini singase siphume ngaphezu kwalokho abafisa. Ngisho nokubeka ukukwenza lokhu uma ungasebenzi lutho imizuzu eyishumi nanhlanu ukuya kwemizuzu engamashumi amathathu kungenza umehluko omkhulu. Lokhu kungalungiswa kuzilungiselelo ze-Mac Enery Saver noma iWindows Power Management .
- Sebenzisa umsindisi wesibuko ojikelezayo uye wahambisa izithombe ezithombeni noma ezingenalutho. Lokhu kuvimbela isithombe ukuthi siboniswe kwesikrini isikhathi eside kakhulu.
- Phenduka noma yiziphi izithombe zangemuva kwideskithophu. Imidwebo yangemuva ingenye yezimbangela ezivame kakhulu zokuphikelela kwesithombe. Ngokushintsha izizinda nsuku zonke noma izinsuku ezimbalwa, kufanele kunciphise amathuba okuphikelela.
- Vala ukuqapha lapho uhlelo lungasebenzi. Lokhu kuzokuvimbela noma yiziphi izinkinga lapho umsebenzi weskrini noma amandla omsebenzi ehluleka ukuvala isikrini futhi kubangele isithombe esihle esibukweni isikhathi eside.
Ukusebenzisa lezi zinto kungasiza ekuvimbeleni inkinga yokuphikelela kwesithombe ukungena kwi-monitor. Kodwa kuthiwani uma i-monitor isivele ibonisa ezinye izinkinga zokuphikisa isithombe? Nazi izinyathelo ezimbalwa ezingasetshenziswa ukuzama ukuzilungisa:
- Vala ukuqapha isikhathi esithile. Kungaba njengamahora amaningana noma kungase kube izinsuku eziningana.
- Sebenzisa isilondolozi sesikrini ngesithombe esijikelezayo bese ugijima isikhathi eside. (Lokhu kwenziwa ngokubeka umsikisi weskrini ojikelezayo futhi ukhubaza ukubhekwa kokulinda kokulala.) Iphalethi enombala ejikelezayo kufanele isuse isithombe sokuphikisana kodwa kungathatha isikhashana ukususa.
- Vula isikrini ngombala owodwa oqinile noma umhlophe okhanyayo isikhathi eside. Lokhu kuzokwenza zonke izikristali ziphinde zihlelwe esimweni esisodwa sombala futhi kufanele zisuse noma yikuphi ukuphikelela kwesithombe esidlule.
Uma ubuyela emuva efanini le-window ye-shutter, lezi zinyathelo zifana kakhulu nokugcizelela i-shutter yefasitela ukuze ekugcineni uzithole unganhlanhla ukuze ikwazi ukuchaza ngokugcwele ukunikeza noma yikuphi ukukhanya okufisa ukudlula.
Iziphetho
Ngenkathi ama-LCD angenayo inkinga efanayo yokushisa eyathinta i-CRTs, inkinga yokuphikelela kwesithombe ingavela. Sethemba ukuthi lesi sihloko sibhekisele ukuthi yikuphi ukukhathazeka, ukuthi kubangelwa yini, kanjani ukuyivimbela nokuthi ingayilungisa kanjani. Ngayo yonke izinyathelo zokuvimbela endaweni, umsebenzisi akufanele neze ahlangabezane nale nkinga.
