Boemo ba nts'etsopele ea TFT LCD

Lits'oants'o tsa mebala tsa TFT (Thin-Film Transistor), e le karolo ea mantlha ea theknoloji ea sejoale-joale ea ponts'o, li bile le liphetoho tse potlakileng tsa theknoloji le katoloso ea mmaraka ho tloha ha li rekisoa ka bo-1990. E lula e le tharollo ea mantlha ea lisebelisoa tsa elektroniki tsa bareki, lisebelisoa tsa indasteri le likarolo tse ling. Tlhahlobo e latelang e hlophisitsoe ka likarolo tse tharo: histori ea tsoelo-pele, boemo ba morao-rao ba theknoloji, le litebello tsa nako e tlang.

I. Nalane ea Nts'etsopele ea TFT-LCD
Khopolo ea theknoloji ea TFT e hlahile lilemong tsa bo-1960, empa e ne e se ho fihlela lilemong tsa bo-1990 moo lik'hamphani tsa Majapane li ileng tsa finyella tlhahiso ea bongata ba khoebo, haholo-holo bakeng sa li-laptops le li-monitor tsa pele tsa LCD. Li-TFT-LCD tsa moloko oa pele li ne li hatelloa ke qeto e tlase, theko e phahameng, le tlhahiso e tlase ea tlhahiso, empa butle-butle li ile tsa nkela lipontšo tsa CRT sebaka ka lebaka la melemo e kang slim form factor le tšebeliso e tlase ea matla. Ho tloha ka 2010 ho ea pele, li-TFT-LCD li ile tsa kenella limmarakeng tse kang li-smartphone, lipontšo tsa likoloi, lisebelisoa tsa bongaka le mekhoa ea ho laola indasteri, ha li ntse li tobane le khatello ea tlhōlisano e tsoang ho OLED. Ka lintlafatso tsa theknoloji tse kang Mini-LED backlighting, ts'ebetso e matlafalitsoe lits'ebetsong tse ling, ho kenyeletsoa le li-monitor tsa maemo a holimo.

II. Boemo ba hajoale ba Theknoloji ea TFT-LCD
Ketane ea indasteri ea TFT-LCD e holile haholo, 'me litšenyehelo tsa tlhahiso li tlase haholo ho feta tsa OLED, haholo lits'ebetsong tsa boholo bo boholo joalo ka li-TV le li-monitor, moo e laolang' maraka. Khatello ea tlholisano le boqapi li tsamaisoa haholo ke phello ea OLED. Le hoja OLED e sebetsa hantle ho feta tekano le karo-karolelano ea ho bapisa (ka lebaka la tlhaho ea eona ea boithati e nang le phapang e sa feleng), TFT-LCD e fokolitse lekhalo ka ho amohela khanya ea Mini-LED e nang le dimming ea sebakeng seo ho ntlafatsa ts'ebetso ea HDR. Khokahano ea theknoloji e boetse e matlafalitsoe ka matheba a quantum (QD-LCD) bakeng sa papali ea mebala e pharalletseng le ho kenyelletsoa ha theknoloji ea touch, ho eketsa boleng bo eketsehileng.

III. Litebello tsa kamoso tsa TFT-LCD
Mini-LED backlighting, e nang le li-micro-LED tse likete bakeng sa ho fifala ha lehae, e fihlela maemo a fapaneng a haufi le a OLED ha a ntse a boloka bophelo bo bolelele le melemo ea litšenyehelo tsa LCD. Sena se e beha e le tataiso ea bohlokoa 'marakeng oa lipontšo tse phahameng. Leha TFT-LCD e tenyetsehang e sa fetohe ho feta OLED, bokhoni bo fokolang ba ho kobeha bo lemohuoe ho sebelisoa likhalase tse tšesaane haholo kapa li-substrates tsa polasetiki, tse nolofalletsang tlhahlobo ea lits'ebetso tse joalo ka lisebelisoa tsa likoloi le tse aparoang. Maemo a kopo a ntse a tsoela pele ho atoloha likarolong tse itseng-ka mohlala, mokhoa o lebisang ho li-skrini tse ngata likoloing tse ncha tsa matla li matlafatsa boemo ba TFT-LCD, ka lebaka la ho tšepahala le ho sebetsa hantle ha eona. Keketseho mebarakeng ea mose ho maoatle, joalo ka India le Asia Boroa-bochabela, moo tlhoko ea lisebelisoa tsa elektroniki e ntseng e phahama, e boetse e ts'ehetsa ts'epo ea TFT-LCD lipakeng tsa lisebelisoa tse tlase ho isa tlase.

OLED e laola li-smartphone tsa boemo bo holimo le limmaraka tse bonolo tsa ponts'o 'me e sebelisana le Micro LED, e shebaneng le li-skrini tse kholo (mohlala, mabota a video a khoebo). Ho sa le joalo, TFT-LCD e ntse e tsoela pele ho kenella limmarakeng tsa boholo bo bohareng ho isa ho tse kholo ka lebaka la sekhahla sa ts'ebetso ea eona. Kamora mashome a lilemo a nts'etsopele, TFT-LCD e se e holile, leha ho le joalo e boloka ts'ebetso ea nako e telele ka boqapi ba mahlale a kang Mini-LED le IGZO, hammoho le ka ho kena mebarakeng ea niche joalo ka lits'ebetso tsa likoloi le tsa indasteri. Molemo oa eona oa mantlha o ntse o le teng: litšenyehelo tsa tlhahiso ea liphanele tse kholo li tlase haholo ho feta tsa OLED.

Ha re sheba pele, TFT-LCD e tla shebana haholo le tlholisano e fapaneng ho fapana le ho tobana le OLED ka kotloloho. Ka tšehetso ea mahlale a kang Mini-LED backlighting, ho lebelletsoe ho theha menyetla e mecha 'marakeng oa maemo a holimo. Le hoja mefuta-futa ea theknoloji ea pontšo e le mokhoa o ke keng oa khutlisetsoa morao, TFT-LCD, e tšehelitsoeng ke tikoloho e hōlileng tsebong le boqapi bo tsoelang pele, e tla lula e le theknoloji ea motheo indastering ea lipontšo.
