Txoj kev loj hlob ntawm TFT LCD

Cov ntxaij vab tshaus xim TFT (Thin-Film Transistor), ua ib feem tseem ceeb ntawm cov thev naus laus zis niaj hnub no, tau dhau los ntawm kev hloov pauv thev naus laus zis sai sai thiab kev nthuav dav ntawm kev ua lag luam txij li thaum lawv tau muag hauv xyoo 1990. Lawv tseem yog cov kev daws teeb meem tseem ceeb hauv cov khoom siv hluav taws xob, cov khoom siv hauv kev lag luam, thiab lwm yam. Cov kev tshuaj xyuas hauv qab no tau teeb tsa ua peb yam: keeb kwm kev loj hlob, qhov xwm txheej thev naus laus zis tam sim no, thiab kev cia siab yav tom ntej.

I. Keeb Kwm Kev Loj Hlob ntawm TFT-LCD
Lub tswv yim ntawm TFT thev naus laus zis tau tshwm sim hauv xyoo 1960, tab sis nws tsis yog txog thaum xyoo 1990 uas cov tuam txhab Nyij Pooj tau ua tiav kev tsim khoom loj, feem ntau yog rau cov khoos phis tawj thiab cov saib LCD thaum ntxov. Cov TFT-LCD thawj tiam tau raug txwv los ntawm kev daws teeb meem qis, tus nqi siab, thiab cov txiaj ntsig tsim khoom qis, tsis tau lawv maj mam hloov cov zaub CRT vim muaj qhov zoo xws li cov qauv nyias thiab kev siv hluav taws xob tsawg. Txij li xyoo 2010 mus, TFT-LCD tau nkag mus rau hauv kev lag luam xws li smartphones, cov zaub tsheb, cov khoom siv kho mob, thiab cov tshuab tswj kev lag luam, thaum tseem ntsib kev sib tw los ntawm OLED. Los ntawm kev hloov kho thev naus laus zis xws li Mini-LED backlighting, kev ua tau zoo tau txhim kho hauv qee daim ntawv thov, suav nrog cov saib siab.

II. Cov Txheej Txheem Kev Siv Tshuab Tam Sim No ntawm TFT-LCD
Cov saw hlau lag luam TFT-LCD tau loj hlob sai heev, nrog rau cov nqi tsim khoom qis dua li OLED, tshwj xeeb tshaj yog hauv cov ntawv thov loj xws li TVs thiab monitors, qhov twg nws tswj hwm kev ua lag luam. Kev sib tw thiab kev tsim kho tshiab yog qhov tseem ceeb tsav los ntawm qhov cuam tshuam ntawm OLED. Thaum OLED ua tau zoo dua hauv kev ywj pheej thiab qhov sib piv sib piv (vim nws tus kheej-emissive xwm nrog qhov sib piv tsis kawg), TFT-LCD tau nqaim qhov sib txawv los ntawm kev siv Mini-LED backlighting nrog lub zos dimming los txhim kho kev ua tau zoo HDR. Kev koom ua ke ntawm thev naus laus zis kuj tau txhim kho los ntawm quantum dots (QD-LCD) rau cov xim gamut dav dua thiab kev koom ua ke ntawm cov thev naus laus zis kov, ntxiv tus nqi ntxiv.

III. Yav tom ntej ntawm TFT-LCD
Mini-LED backlighting, nrog nws ntau txhiab micro-LEDs rau kev tsaus ntuj hauv zos, ua tiav cov qib sib piv ze rau cov OLED thaum tswj hwm lub neej ntev thiab cov txiaj ntsig ntawm LCD. Qhov no tso nws ua qhov tseem ceeb hauv kev lag luam zaub siab. Txawm hais tias TFT-LCD yooj ywm tsis yooj yim hloov pauv ntau dua li OLED, muaj peev xwm khoov tau txwv los ntawm kev siv cov iav ultra-thin lossis yas substrates, ua rau kev tshawb nrhiav rau hauv cov ntawv thov xws li tsheb thiab cov khoom siv hnav. Cov xwm txheej ntawm daim ntawv thov txuas ntxiv nthuav dav hauv qee qhov ntu - piv txwv li, qhov sib txawv ntawm ntau lub vijtsam hauv cov tsheb fais fab tshiab txhawb nqa TFT-LCD lub xeev tseem ceeb, vim nws qhov kev ntseeg siab thiab kev siv nyiaj tsim nyog. Kev loj hlob hauv kev lag luam txawv teb chaws, xws li Is Nrias teb thiab Southeast Asia, qhov twg qhov kev thov rau cov khoom siv hluav taws xob rau cov neeg siv khoom nce siab, kuj txhawb nqa kev vam khom rau TFT-LCD hauv nruab nrab mus rau qis kawg.

OLED tswj hwm cov xov tooj ntse siab kawg thiab cov khw muag khoom yooj ywm thiab nyob ua ke nrog Micro LED, uas tsom mus rau cov ntxaij vab tshaus loj heev (piv txwv li, phab ntsa video lag luam). Lub caij no, TFT-LCD txuas ntxiv mus rau hauv nruab nrab-rau-loj-loj kev lag luam vim nws qhov sib piv ntawm tus nqi-kev ua tau zoo. Tom qab ntau xyoo ntawm kev txhim kho, TFT-LCD tau mus txog qhov loj hlob, tab sis nws tswj hwm kev ua tau zoo mus sij hawm ntev los ntawm kev tsim kho tshiab xws li Mini-LED thiab IGZO, nrog rau kev siv rau hauv cov khw muag khoom me me xws li tsheb thiab kev siv hauv kev lag luam. Nws qhov txiaj ntsig tseem ceeb tseem nyob: tus nqi tsim khoom rau cov vaj huam sib luag loj yog qis dua li OLED.

Saib mus tom ntej, TFT-LCD yuav tsom mus rau kev sib tw sib txawv ntau dua li ntsib OLED ncaj qha. Nrog kev txhawb nqa ntawm cov thev naus laus zis zoo li Mini-LED backlighting, nws xav tias yuav tsim cov cib fim tshiab hauv kev lag luam siab. Txawm hais tias kev sib txawv ntawm cov thev naus laus zis tso saib yog qhov sib txawv tsis hloov pauv, TFT-LCD, txhawb nqa los ntawm lub ecosystem laus thiab kev tsim kho tshiab tas mus li, yuav tseem yog cov thev naus laus zis tseem ceeb hauv kev lag luam tso saib.
