Kungani ukuboniswa kwe-LCD kudinga ukuhlolwa kokuguga ngaphambi kokushiya ifektri?

I-Liquid Crystal Display (LCD) isibe yingxenye ebalulekile yezimpilo zethu zansuku zonke, ikhona kumadivayisi ahlukahlukene afana nama-Smartphones, amathelevishini, abaqaphi bekhompyutha, nokuningi. Njengabathengi, silindele ukuthi le ndlela yokubonisa isebenza ngokungafanele kusukela lapho zingafakwanga khona. Kodwa-ke, ukuqinisekisa ukuthembeka nokuphila isikhathi eside kwezimpawu ze-LCD, abakhiqizi baqhuba isinyathelo esibalulekile esaziwa ngokuthi ukuhlolwa kokuguga ngaphambi kokushiya ifektri. Lo mbhalo uhlose ukuchaza izizathu ngemuva kwesidingo sokuhlolwa kokuguga, okubandakanyayo, noma ngabe kulimaza ukuboniswa kwe-LCD, nokuthi kungani kungahle kube khona amacala lapho kubonisa khona ukuhlolwa kokuguga yize kuphambuka naphezu kokuhlolwa kokuguga naphezu kokuphumelela kokuhlolwa.

Izizathu zokwenza isivivinyo sokuguga:

1. Ukuqinisekiswa kwekhwalithi:
Isizathu esiyinhloko sokuboniswa kwe-LCD ekuhlolweni kokuguga ukuqinisekisa ukuqinisekiswa kwekhwalithi. Lezi zivivinyo zenziwa kukhomba noma yiziphi izici ezingaba khona, ubuthakathaka, noma ukungasebenzi kahle okungase kuveze isikhathi. Ngokulingisa ukusetshenziswa kokuboniswa kwesikhathi eseluliwe, abakhiqizi bangabona izingqinamba ezingase zibonwe ngesikhathi sokuhlolwa kokuqala. Le nqubo isiza ukuletha umkhiqizo ohlangabezana namazinga aphezulu kakhulu wekhwalithi nokwethembeka.

2. Ukuhlolwa kokuqina:
Ukuboniswa kwe-LCD kuqukethe izinto ezahlukahlukene, kufaka phakathi amakristalu awuketshezi, i-backlight, ama-polarizer, kanye nokulawula ukujikeleza. Ngayinye yalezi zinto ingathinteka yizinto ezifana nokushisa, umswakama kanye nokushintshashintsha kwamandla kagesi. Ukuhlolwa kokuguga kuvumela abakhiqizi ukuthi bahlole ukuqina kwalezi zingxenye ngaphansi kwezimo ezahlukahlukene, ukuqinisekisa ukuthi bangamelana nobunzima bokusetshenziswa kwangempela komhlaba. Kuyasiza ekuboneni noma ibuphi ubuthakathaka obungaba khona noma ubungozi obungenza isibonisi sehluleke ngaphambi kwesikhathi.

3. Ukuhlolwa kokusebenza:
Ukuhlolwa kokuguga nakho kusebenza njengendlela yokuhlola ukusebenza kwesibonisi se-LCD. Ivumela abakhiqizi ukuthi balinganise futhi bahlaziye amapharamitha anjengokunemba kwemibala, umehluko, ukufana kokukhanya, isikhathi sokuphendula, kanye nokubuka ama-engeli. Ngokufaka isibonisi ekusetshenzisweni isikhathi eside, abakhiqizi bangahlola amandla bawo okugcina ukusebenza okungaguquki ngokuhamba kwesikhathi. Lokhu kuhlola kusiza ekuletheni imibukiso enikeza isipiliyoni esifanele sokubuka kubasebenzisi bokugcina.

Inqubo yokuhlola ubudala nomthelela wayo kwi-LCD Display:

Ukuhlolwa kokuguga ngokuvamile kubandakanya ukubhekana nokuboniswa kwe-LCD ekusebenzeni okuqhubekayo isikhathi eside, kuvame ukusukela emahoreni ambalwa kuya ezinsukwini ezimbalwa. Isibonisi sixhumeke ohlelweni lokuhlola olukhiqiza amaphethini ahlukahlukene, imibala, kanye nezithombe ukwenza izimo zangempela zokusetshenziswa komhlaba. Uhlelo lokuhlola luqapha futhi luqopha amapharamitha wokusebenza ngokubonisa kuyo yonke inqubo yokuguga.

Ngokuphikisana nenkolelo ethandwayo, ukuhlolwa kokuguga ngokwako akulimazi ukubonisa kwe-LCD. Isivivinyo senzelwe ukulingisa izimo ezijwayelekile zokusetshenziswa ukuthi isibonis sizohlangabezana nazo ngesikhathi sokuphila kwaso. Abakhiqizi bathatha izinyathelo zokuqapha ukuze baqinisekise ukuthi imvelo yokuhlola, kufaka phakathi izinga lokushisa, umswakama kanye namazinga we-voltage, lihlala linemikhawulo ephephile. Inhloso ukukhomba noma yiziphi izingqinamba ezingaba khona ezingase ziphakame ngesikhathi sokusetshenziswa njalo, hhayi ukudala umonakalo.

Ukuhlolwa kokuguga kuthinta isibani se-backlight, esibhekele ukukhanyisela amakristalu awuketshezi futhi kukhiqize izithombe esizibonayo. Izibani zangemuva zivame ukuhlanganisa ama-diode akhanyisekayo (ama-LED) noma izibani ezibandayo ze-fluode fluorescent (CCFLS). Le mithombo ekhanyayo ilulaza ngokuhamba kwesikhathi, okuholela ekukhazimulweni okuncishisiwe, amashifu anemibala, noma ukwehluleka okuphelele. Ngokubheka ukukhanya kwemuva kuya ekusebenzeni okuqhubekayo ngesikhathi sokuhlolwa kokuguga, abakhiqizi bangakhomba noma yiziphi izingqinamba ezihlobene ne-backlight futhi baqinisekise isikhathi eside sayo.

Yize edlulisela isivivinyo sokuguga, kungani ezinye zibonisa zehluleka?

Ngenkathi ukuhlolwa kokuguga kuyisinyathelo esibalulekile ekuqinisekiseni ikhwalithi nokuthembela kokuboniswa kwe-LCD, kungenzeka kube namacala lapho kubonisa khona ukwehluleka naphezu kokuphumelela kwalesi sivivinyo. Kunezici eziningana ezingaba nomthelela kulowo okuhluleka okunjalo:

1. Izinkinga zokukhiqiza:
Yize ukuhlolwa kokuguga kusiza ukubona iziphambeko eziningi zokukhiqiza, akuzona eziyimpumbi. Ezinye iziphambeko zingangabonakali ngesikhathi sokuhlolwa ngenxa yemvelo yazo engaphakathi noma ukulinganiselwa kokusethwa kokuhlolwa. Lezi ziphutha zingabonakala kuphela ngemuva kokusetshenziswa isikhathi eside noma ngaphansi kwezimo ezithile, okuholela ekubonisweni ukwehluleka.

2. Ukuphatha nokuhamba:
Ukuboniswa kwe-LCD kumadivayisi abucayi futhi abucayi. Ukulungiswa ngesikhathi sokuhamba noma ukufakwa okungafanele kungadala umonakalo ongase ungabonakali ngokushesha. Ngenkathi ukuhlolwa kokuguga kuqinisekisa ukusebenza kwe-Display ngaphambi kokushiya ifektri, izinto zangaphandle ezingaphezu kokwenziwa komkhiqizi zingathinta ukusebenza kwazo ngesikhathi sokuhamba noma ukufakwa.

3. Izici zezemvelo:
Ukuboniswa kwe-LCD kutholakala ngenxa yezici zezemvelo ezifana lokushisa, umswakama, kanye nokuchayeka elangeni. Yize ukuhlolwa kokuguga kulingisa izimo zokusetshenziswa, akunakuphendula konke ukuhlukahluka kwemvelo okungenzeka ukuthi isibonisi singase sihlangane nakho uma sifinyelela kumsebenzisi wokugcina. Amazinga okushisa aphezulu, umswakama ophezulu, noma ukuvezwa isikhathi eside kokukhanya kwelanga kungadalula ukusebenza nokuphila isikhathi eside kwesibonisi, okuholela ekwahlulekeni.

4. Ukusebenzisa kabi umsebenzisi noma ukunganaki:
Kwezinye izimo, imibukiso ingahle yehluleke ngenxa yokusebenzisa kabi komsebenzisi noma ukunganaki. Ukusingathwa okungalungile, izindlela zokuhlanza ezingalungile, noma ukubonwa koketshezi kungalimaza isibonisi, kungakhathalekile ukuthi kudlule isivivinyo sokuguga. Kubalulekile ukuthi abasebenzisi balandele imihlahlandlela yomenzi yokusetshenziswa okufanele kanye nokulungiswa ukuze kuqinisekiswe isikhathi eside sokubonisa.

Isiphetho:

Ukuhlolwa kokuguga kudlala indima ebalulekile ekuqinisekiseni ikhwalithi, ukuthembeka kanye nokuphila isikhathi eside kwe-LCD Ekhombisa. Ngokubheka ukuboniswa kokusetshenziswa okunwetshiwe ngaphansi kwezimo ezilawulwayo, abakhiqizi bangabona iziphambeko ezingaba khona, bahlole ukuqina, futhi bahlole ukusebenza. Ngokuphikisana nemibono eyiphutha, ukuhlolwa kokuguga ngokwako akulimazi ukuboniswa. Kodwa-ke, yize edlulisela isivivinyo sokuguga, ngabe kusekhona amacala lapho kukhonjiswa khona ukwehluleka ngenxa yokukhiqiza, ukufakwa ngesikhathi sokuhamba noma ukufakwa, izici zezemvelo, noma ukusetshenziswa kabi komsebenzisi. Kubalulekile ukuthi abakhiqizi kanye nabasebenzisi bokugcina baqonde lezi zinto futhi bathathe izinyathelo zokuphepha ukuqinisekisa ukusebenza okuhle nokuphila isikhathi eside kwe-LCD Ekhombisa.
