Njengesixhobo esichanekileyo sokubonisa i-elektroniki, izikrini ze-LCD ezinombala we-TFT zineemfuno ezingqongqo zokusingqongileyo. Ukusetyenziswa kwansuku zonke, ukulawulwa kweqondo lokushisa yinto ephambili yokuqwalaselwa. Iimodeli eziqhelekileyo zisebenza phakathi koluhlu lwe-0 ° C ukuya ku-50 ° C, ngelixa iimveliso ze-industrial-grade zikwazi ukumelana noluhlu olubanzi lwe -20 ° C ukuya kuma-70 ° C. Amaqondo obushushu aphantsi kakhulu anokubangela ukuphendula okucothayo kwekristale yolwelo okanye umonakalo wecrystallization, ngelixa amaqondo obushushu aphezulu anokukhokelela ekuboniseni ukugqwetheka kunye nokukhawulezisa ukuguga kwamacandelo e-TFT backlight. Nangona iqondo lobushushu obugciniweyo linokuthotywa liye kuthi ga ku-20°C ukuya kuma-60°C, ukuguquguquka okukhawulezileyo kobushushu kusafuneka kuphetshwe. Ingqwalasela ekhethekileyo kufuneka ihlawulwe ekuthinteleni ukuxinana okubangelwa utshintsho olukhawulezayo lobushushu, njengoko oku kunokubangela umonakalo wesiphaluka ongenakuguqulwa.
Ulawulo lokufuma lubalulekile ngokulinganayo. Indawo yokusebenza kufuneka igcine ukufuma okungama-20% ukuya kuma-80%, ngelixa iimeko zogcino kufuneka zigcinwe phakathi kwe-10% kunye ne-60%. Ukufuma okugqithisileyo kunokubangela ukuthotywa kwesekethe kunye nokukhula komngundo, ngelixa iimeko ezomileyo kakhulu zonyusa umngcipheko wokukhutshwa kwe-electrostatic discharge (ESD), enokonakalisa ngephanyazo amacandelo omboniso obuthathaka. Xa uphatha isikrini kwiindawo ezomileyo, amanyathelo abanzi achasene ne-static kufuneka aphunyezwe, kubandakanywa nokusetyenziswa kwe-anti-static wrist straps kunye neendawo zokusebenza.
Iimeko zokukhanyisa zichaphazela ngqo ixesha elide lesikrini. Ukuboniswa ixesha elide kukukhanya okunamandla, ngakumbi imisebe ye-ultraviolet (UV), inokuthoba i-polarizers kunye nezihluzo zemibala, ezikhokelela kumgangatho ophantsi wokuboniswa. Kwiindawo zokukhanya okuphezulu, ukwandisa ukukhanya kwe-TFT backlight kunokuba yimfuneko, nangona oku kuya kuphakamisa ukusetyenziswa kwamandla kunye nokunciphisa umva wokuphila. Ukukhuselwa komatshini yenye into ephambili yokuqwalaselwa-izikrini ze-TFT zibuthathaka kakhulu, kwaye nokungcangcazela okuncinci, iimpembelelo, okanye uxinzelelo olungafanelekanga lunokubangela umonakalo ongunaphakade. Ukufunxa ngokufanelekileyo umothuko kunye nokuhanjiswa kwamandla kufuneka kuqinisekiswe ngexesha lofakelo.
Ukukhuselwa kweekhemikhali akufanele kuhoywe. Isikrini kufuneka sigcinwe kude nezinto ezitshabalalisayo, kwaye kuphela ii-agent zokucoca ezizinikeleyo kufuneka zisetyenziswe-utywala okanye ezinye izinyibilikisi kufuneka ziphetshwe ukuze kuthintelwe umonakalo kwiingubo ezingaphezulu. Ulondolozo lwesiqhelo kufuneka luquke uthintelo lothuli, njengoko uthuli oluqokelelweyo aluchaphazeli inkangeleko kuphela kodwa lunokuthi luthintele ukukhutshwa kobushushu okanye lubangele ukungasebenzi kakuhle kwesekethe. Kwizicelo ezisebenzayo, kuyacetyiswa ukuba ulandele ngokungqongqo iiparamitha zokusingqongileyo ezichazwe kwidatha yemveliso. Kwiindawo ezifuna amandla (umzekelo, umzi-mveliso, iimoto, okanye ukusetyenziswa kwangaphandle), iimveliso zodidi lwemizi-mveliso ezinokuqina okwandisiweyo kufuneka zikhethwe. Ngokuphumeza ulawulo olubanzi lokusingqongileyo, umboniso we-TFT unokufezekisa ukusebenza kakuhle kunye nobomi benkonzo eyandisiweyo.
