Kutheni le nto i-LCD ibonisa uvavanyo lokuphatha ngaphambi kokuba liphume kumzi-mveliso?

I-Crystal ye-crystal ye-freetal (LCD) iye yaba yinxalenye yobomi bethu yemihla ngemihla, ekhoyo kuluhlu olubanzi lwezixhobo ezinjengee-smartphones, umabonwakude, amajelo enza ikhompyuter, nangaphezulu. Njengabathengi, silindele ukuba ezi zinto zibonisa ukuba zisebenze ngokungagungqiyo ukusuka kumzuzu abangaboniyo. Nangona kunjalo, ukuqinisekisa ukuthembeka kunye nobomi obude kwi-LCD, abavelisi beqhuba inyathelo elibalulekileyo elaziwa njengovavanyo lokwaluphala ngaphambi kokuba bashiye umzi-mveliso. Eli nqaku lijolise ekucaciseni izizathu zemfuno yovavanyo olulupheleyo, ukubandakanya, nokuba kuyonakalisa i-LCD, kwaye kutheni kusenokubakho amatyala apho ubonakaliso lokwaluphala.

Izizathu zokwenza uvavanyo lokwaluphala:

1. Ukuqinisekiswa komgangatho:
Esona sizathu siphambili sokuthoba i-LCD ibonisa uvavanyo lokwaluphala kukuqinisekisa ukuqinisekiswa komgangatho. Ezi mvavanyo zenziwa ukuba zichonge nasiphi na isiphene esinokubakho, ubuthathaka, okanye ukungasebenzi kakuhle kunokuvela ixesha elingaphezulu kwexesha. Ngokusebenzisa ukusetyenziswa kwendlela yokubonisa ixesha elide, abavelisi banokufumana imiba enokuthi ingaziwa xa kuhlolwa kuqala. Le nkqubo inceda ekunikezeleni imveliso ehlangabezana nemigangatho ephezulu yomgangatho kunye nokuthembeka.

2. UVAVANYO LOLWAZI:
Imiboniso ye-LCD iquka izinto ezahlukeneyo, kubandakanya iikristale ezingamanzi, i-backlight, i-polarliners, kunye nokujikeleza. Inye yezi zinto inokuchaphazeleka zizinto ezinje ngobushushu, umswakama, kunye nokutshintsha kwe-voltage. Uvavanyo lokudala luvumela abavelisi ukuba bahlole uzinzo kwezi zinto phantsi kweemeko ezahlukeneyo, ukuqinisekisa ukuba banokumelana neengqolowa zokusetyenziswa kwehlabathi. Kuyanceda ekuchongeni nakuphi na ukuqina okanye ubungozi obunokubangela ukuba umboniso ulele ngaphambi kwexesha.

3. Uvandlakanyo lwentsebenzo:
Uvavanyo lokudala lukwasebenza njengendlela yokuvavanya ukusebenza kwesibonisi se-LCD. Ivumela abavelisi ukuba bahlalutye kwaye bahlalutya iiparamitha ezinjengokuchaneka kombala, ukuthelekisa umlinganiso, ixesha lokuqaqamba, kunye nokujonga ii-angles. Ngokuthobela umboniso wokusetyenziswa ixesha elide, abavelisi banokuvavanya amandla ayo okugcina ukusebenza okungaguqukiyo ngokuhamba kwexesha. Olu vavanyo lunceda ekunikezeleni imiboniso ebonelela ngamava abonakalayo abonakalayo kumachaphaza aphezulu.

INKQUBO YOKUGQIBELA YABASEBENZI kunye nefuthe layo kumboniso we-LCD:

Uvavanyo olulukhuni luhlala lubandakanya ukuthoba i-LCD ukubonisa ukusebenza kwexesha elongeziweyo, lihlala lisusela kwiiyure ezininzi ukuya kwiintsuku ezininzi. Umboniso uqhagamshelwe kwinkqubo yovavanyo evelisa iipateni ezahlukeneyo, imibala kunye nemifanekiso yokulinganisa imeko yangempela yehlabathi. Inkqubo yovavanyo ibeka iliso kwaye irekhoda iparamitha yokubonisa umboniso kuyo yonke inkqubo yokwaluphala.

Ngokuchasene nenkolelo ethandwayo, uvavanyo lokuguga ngokwalo alusonakalisi umboniso we-LCD. Olu vavanyo lwenzelwe ukulinganisa iimeko zokusetyenziswa okuqhelekileyo eziza kudibana nazo ngexesha lobomi balo. Abavelisi bathathe amanyathelo okhuseleko ukuqinisekisa ukuba indalo yovavanyo, kubandakanya iqondo lokushisa, umswakama, kunye namanqanaba evolthi, ihlala ngaphakathi kwemida ekhuselekileyo. Injongo kukuchonga nayiphi na imiba enokubakho enokuthi ivele ngexesha lokusetyenziswa rhoqo, ukungabi kwenza umonakalo.

Uvavanyo oluninzi oluyintloko luchaphazela ukukhanya kwegama lokubonisa, elinoxanduva lokukhanyisa amakristali olwelo kwaye uvelise imifanekiso esiyibonayo. Izibane ezingasemva zibandakanya ii-Dods ezikhuphayo ezikhutshelweyo Le mithombo ilula imithombo ihlazisa ngokuhamba kwexesha, kukhokelela ekunciphiseni ukuqaqamba, ukutshintsha kombala, okanye ukusilela ngokupheleleyo. Ngokuthobela isibane esingasemva ukuya kuphumeza okuqhubekayo ngexesha lovavanyo lokwaluphala, abavelisi banokuchonga nayiphi na imiba enxulumene nelikhasi kwaye baqinisekise ukuba lubomi obude.

Ngaphandle kokuphumelela kuvavanyo lokuguga, kutheni le nto ezinye ibonisa?

Ngelixa uvavanyo lokwaluphala linyathelo elibalulekileyo ekuqinisekiseni umgangatho kunye nokuthembeka kwe-LCD, kusenokuba kusekho amatyala apho imiboniso ilele ngaphandle kokuphumelela kolu vavanyo. Izinto ezininzi zinokuba negalelo kulwaziso:

1. Ukuvelisa iziphene:
Nangona uvavanyo lokwaluphala lunceda ekuchongeni iziphene zemveliso, asiyonyani. Ezinye iziphene zinokuhamba zingabonwa ngexesha lovavanyo ngenxa yendalo yabo, okanye umda wokuseta uvavanyo. Ezi ziphene zinokubonakalisa kuphela emva kokusetyenziswa kwexesha elide okanye phantsi kweemeko ezithile, kukhokelela ekungabonisiyo.

2. Ukuphatha kunye nokuhamba:
Ukuboniswa kwe-LCD kuyacekeceke kwaye zinobuthathaka. Ukungagungqi ngexesha lokuhamba okanye ukufakelwa okungafanelekanga kunokubangela umonakalo onokuthi ungabonakali kwangoko. Ngelixa uvavanyo lokwaluphala luqinisekisa ukusebenza komboniso ngaphambi kokuba uphume umzi-mveliso, izinto zangaphandle Izinto ezingaphaya kolawulo lomelo lungayichaphazela intsebenzo yayo ngexesha lokuhamba okanye ukufakelwa.

3. IMIQATHANGO EZIQHELEKILEYO:
Ukuboniswa kwe-LCD kukhuselwe kwizinto zokusingqongileyo ezinje ngamaqondo obushushu, umswakama, kunye nokuchatshazelwa ukukhanya kwelanga. Nangona uvavanyo lokudala lucima iimeko zokusenisa, ayinakho ukuphendula kuzo zonke izinto ezinokwenzeka zokusingqongileyo ukuba umboniso unokudibana naye kanye ukuba ifikelela kumsebenzisi wokugqibela. Ubushushu obugqithisileyo, umswakama ophezulu, okanye ukubonakaliswa kwexesha elide lokukhanya kwelanga kuya kuncipha intsebenzo kunye nokuhlala kwezinto ezibonakalalisiweyo, kukhokelela ekungathobeni.

4. Sebenzisa gwenxa okanye ukungakhathali:
Ngamanye amaxesha, imiboniso isenokungaphumeleli ngenxa yokusebenzisa kakubi umsebenzisi okanye ukungakhathali. Ukuphatha kakubi, iindlela zokucoca ezingalunganga, okanye ukuveza ulwelo lunokonakalisa umboniso, nokuba ungadlulanga uvavanyo olulupheleyo. Kubalulekile ukuba abasebenzisi balandele izikhokelo zomenzi zokusetyenziswa okufanelekileyo kunye nolondolozo lokuqinisekisa ukuba ubomi obude.

ISIQINISEKISO:

Uvavanyo lokudala ludlala indima ebalulekileyo ekuqinisekiseni umgangatho, ukuthembeka, kunye nokuhlala kobomi be-LCD. Ngokuthobela imiboniso yokusetyenziswa okwandisiweyo phantsi kweemeko ezilawulwayo, abavelisi banokuchonga iziphene ezinokubakho, uvavanyo lokuvavanya, kunye nokuvavanya intsebenzo. Ngokuchasene nembono ephosakeleyo, uvavanyo lokuguga ngokwalo aluyonakalisi imiboniso. Nangona kunjalo, ngaphandle kokuphumelela kuvavanyo lokuguga, kusekho amatyala apho imiboniso isilele ngenxa yokwenza iziphene, ukungasebenzi kakuhle ngexesha lokuhamba okanye ukufakelwa, izinto zokusingqongileyo, okanye ukusetyenziswa gwenxa komsebenzisi. Kubalulekile ukuba abavelisi kunye nabasebenzisi abaphelela ukuba baqonde ezi zinto kwaye bathathe amanyathelo afanelekileyo okuqinisekisa ukuba i-practions ifanelekileyo kunye nobomi obude be-LCD.
