Imeko yophuhliso lwe-TFT LCD

Izikrini zombala zeTFT (Thin-Film Transistor), njengenxalenye ephambili yetekhnoloji yokubonisa yanamhlanje, ziye zaphindaphindwa ngokukhawuleza kwetekhnoloji kwaye zanda imarike ukusukela oko zathengiswa ngeminyaka yoo-1990. Zihlala zisisisombululo esiphambili sokubonisa kwizixhobo ze-elektroniki zabathengi, izixhobo zoshishino, nakwezinye iinkalo. Olu hlalutyo lulandelayo luhlelwe ngokwamacandelo amathathu: imbali yophuhliso, imeko yangoku yetekhnoloji, kunye namathuba exesha elizayo.

I. Imbali yoPhuhliso lwe-TFT-LCD
Ingcamango yetekhnoloji ye-TFT yavela ngeminyaka yoo-1960, kodwa kwaphela ngeminyaka yoo-1990 apho iinkampani zaseJapan zafumana khona imveliso enkulu yorhwebo, ikakhulu kwiilaptops kunye neemonitha ze-LCD zokuqala. Ii-TFT-LCD zesizukulwana sokuqala zazithintelwe yisisombululo esiphantsi, iindleko eziphezulu, kunye nemveliso ephantsi, kodwa zatshintsha kancinci kancinci ii-CRT displays ngenxa yeenzuzo ezifana ne-slim form factor kunye nokusetyenziswa kwamandla aphantsi. Ukususela ngo-2010 ukuya phambili, ii-TFT-LCD zangena kwiimarike ezifana nee-smartphones, ii-automotive displays, izixhobo zonyango, kunye neenkqubo zolawulo lwemizi-mveliso, ngelixa zijongene noxinzelelo lokhuphiswano oluvela kwi-OLED. Ngokuphucula ubuchwepheshe okufana ne-Mini-LED backlighting, ukusebenza kuye kwaphuculwa kwezinye izicelo, kubandakanya ii-high-end monitors.

II. Imeko yoBugcisa yangoku yeTFT-LCD
Ishishini le-TFT-LCD likhulile kakhulu, kwaye iindleko zemveliso ziphantsi kakhulu kunezo ze-OLED, ngakumbi kwii-application ezinkulu ezifana neeTV kunye neemonitha, apho ilawula khona imarike. Uxinzelelo lokhuphiswano kunye nokuvelisa izinto ezintsha ziqhutywa kakhulu yimpembelelo ye-OLED. Ngelixa i-OLED isebenza ngcono kumlinganiselo wokuguquguquka kunye nowokuthelekisa (ngenxa yendalo yayo yokuzikhupha ngokwayo kunye nomahluko ongapheliyo), i-TFT-LCD inciphise umsantsa ngokusebenzisa i-Mini-LED backlighting ene-local dimming ukuphucula ukusebenza kwe-HDR. Ukuhlanganiswa kwetekhnoloji kuphuculwe ngamachaphaza e-quantum (QD-LCD) kwi-gamut yombala ebanzi kunye nokufakwa kwetekhnoloji yokuchukumisa, oko kongeza ixabiso elongezelelweyo.

III. Amathemba exesha elizayo e-TFT-LCD
I-Mini-LED backlighting, enamawakawaka ee-micro-LED zayo zokukhanya kwendawo, ifikelela kumanqanaba okungafani asondelelene nalawo e-OLED ngelixa igcina ixesha elide kunye neenzuzo zexabiso ze-LCD. Oku kuyibeka njengesikhokelo esiphambili kwimarike yokubonisa ephezulu. Nangona i-TFT-LCD eguquguqukayo ingenakuguquguquka kangako kune-OLED, amandla okugoba alinganiselweyo aye afezekiswa kusetyenziswa iiglasi ezincinci kakhulu okanye iiplastiki, okuvumela ukuphononongwa kwizicelo ezifana nezixhobo zezithuthi kunye nezinxitywayo. Iimeko zesicelo ziyaqhubeka nokwanda kwiindawo ezithile—umzekelo, umkhwa wokujonga izikrini ezininzi kwizithuthi ezintsha zamandla uqinisa imeko ephambili ye-TFT-LCD, ngenxa yokuthembeka kwayo kunye nokusebenza kakuhle kweendleko. Ukukhula kwiimarike zaphesheya, ezifana neIndiya kunye ne-Southeast Asia, apho imfuno yezixhobo ze-elektroniki zabathengi ikhula, ikwagcina ukuxhomekeka kwi-TFT-LCD kwizixhobo eziphakathi ukuya kwezisezantsi.

I-OLED ilawula iimarike ze-smartphone eziphezulu kunye nezibonisi eziguquguqukayo kwaye ihambelana ne-Micro LED, ejolise kwizikrini ezinkulu kakhulu (umz., iindonga zevidiyo zorhwebo). Okwangoku, i-TFT-LCD iyaqhubeka nokungena kwiimarike eziphakathi ukuya kwezinkulu ngenxa yomlinganiselo wayo weendleko-ukusebenza. Emva kwamashumi eminyaka yophuhliso, i-TFT-LCD ifikelele ekuvuthweni, kodwa igcina ukusebenza ixesha elide ngokusebenzisa izinto ezintsha zobuchwepheshe ezifana neMini-LED kunye ne-IGZO, kunye nokusebenzisa iimarike ezincinci ezifana nezicelo zeemoto kunye nezoshishino. Inzuzo yayo ephambili ihlala ikhona: iindleko zemveliso yeepaneli ezinkulu ziphantsi kakhulu kuneze-OLED.

Ukujonga phambili, i-TFT-LCD iza kugxila ngakumbi kukhuphiswano olwahlukileyo endaweni yokujongana ne-OLED ngokuthe ngqo. Ngenkxaso yetekhnoloji efana ne-Mini-LED backlighting, kulindeleke ukuba idale amathuba amatsha kwimarike ephezulu. Nangona ukwahlukahlukana kwetekhnoloji yokubonisa kuyinto engenakuguqulwa, i-TFT-LCD, exhaswa yi-ecosystem evuthiweyo kunye nokuvelisa izinto ezintsha okuqhubekayo, iya kuhlala iteknoloji esisiseko kwishishini lokubonisa.
