Daim duab 1 TFT-LCD architecture thiab module tag nrho qhov project
Feem ntau, LCDs tau ntim nrog cov kua siv lead ua kua txheej nrog lub thickness ntawm li 3 ~ 4um ntawm lub sab sauv thiab qis pob tshab electrodes. Lub tshuab hluav taws xob ntawm cov kua siv lead ua kua interlayer yog tswj los ntawm txoj kev sau cov pixel (Pixel) electrode voltage, thiab tom qab ntawd qhov kev siv ntawm lub teeb kis tau raug hloov kho kom tsim tau qhov ci ntsa iab. Greylevel nruab nrab ntawm qhov tsaus ntuj. Tam sim no, LCD yog tsim los ntawm peb ntu: xim lim (CF), TFT array (TFTArray) substrate thiab backlight module (Backlight) raws li qhia hauv daim duab 1(a). Txhua Pixel ntawm TFT-LCD muaj cov txheej txheem TFT los tswj nws cov nqi hluav taws xob, thiab yog tias lub teeb tsim los ntawm lub teeb pom kev zoo thiab xa tawm los ntawm LC muaj xim sib txawv, liab, xiav, thiab ntsuab (R / B / G) xav tau. . Cov xim resists ntawm peb xim yog tsim rau ntawm CF iav, thiab cov nplais grey yog siv los tsim cov nyhuv tag nrho; Tom qab TFT array thiab CF substrate raws li ua tiav, ces CF lub phaj sab sauv thiab TFT phaj qis yog ntim nrog LC thiab sib txuas ua ke, Thaum kawg, muab cov polarizer (Polarizer), cov txheej txheem no hu ua "LCD txheej txheem"; thiab qhov kawg "LCM txheej txheem", uas yog kev sib txuas ntawm tus tsav tsheb IC thiab cov tswj Circuit Court board (PCBA) thiab cov iav substrate (JIProcess), thiab tom qab ntawd Lub backlight module yog sib sau ua ke (MAProcess), thiab thaum kawg yog qhov teeb pom kev zoo ntawm lub module... thiab lwm yam raws li qhia hauv daim duab 1(b).
Qhov zoo ntawm AUOTFT-LCD txheej txheem thev naus laus zis
Daim duab 2 iav substrate loj
Siv zog siv ntsuab ntau lawm technology
Txoj kev loj hlob ntawm cov txheej txheem thev naus laus zis niaj hnub no tsis muaj dab tsi ntau dua li kev ua kom yooj yim ntawm cov txheej txheem thiab xaiv cov khoom siv raw thiab cov khoom siv los ua kom cov txheej txheem tawm los thiab tsim khoom, thiab txo cov nqi tsim khoom. Cov peev peev ntawm cov khoom siv hauv ntej-kawg TFTArray thiab CF cov txheej txheem suav nrog ntau dua 60 feem pua ntawm tag nrho cov kev siv nyiaj TFT-LCD. Yog li ntawd, txoj kev tshawb fawb thiab kev loj hlob ntawm cov txheej txheem pem hauv ntej yog tsom rau kev ua kom yooj yim ntawm cov txheej txheem thiab txhim kho kev siv cov ntaub ntawv raw: piv txwv li, plaub-channel daim npog ntsej muag thev naus laus zis uas yooj yim rau cov txheej txheem npog ntsej muag (saib daim duab 3 (a)) thiab cov qauv tsim. txoj kev tsis raug thiab etching. Tsis tas li ntawd, kev siv cov iav thinned substrates tsis tsuas yog txo qhov kev noj cov iav raw cov ntaub ntawv, tab sis kuj muaj qhov zoo ntawm cov khoom hnyav dua thiab cov khoom zoo dua qub; nyob rau tib lub sijhawm, nws tuaj yeem ua tiav cov hom phiaj ntawm kev txuag hluav taws xob thiab txo cov khib nyiab xws li txo cov khoom ntim thiab txhim kho kev thauj mus los. Raws li rau LCM, nrog rau kev loj hlob sai ntawm rooj vag tsav Circuit Court substrate thev naus laus zis (GateonArray, GOA) thiab HSD (Halfsourcedriving) thev naus laus zis hauv daim duab 3(b), nws tsis tsuas yog ua kom yooj yim cov khoom siv ntawm cov tsoos vaj huam sib luag ntawm ntau tus neeg tsav tsheb ICs, tab sis kuj pab LCM muaj peev xwm ntau lawm. Nyob rau hauv cov nqe lus ntawm module backlights, hloov cov tsoos txias cathode hlab nrog lub teeb emitting diodes (LEDs) tsis tsuas yog zam kev puas tsuaj ntawm mercury (Hg) vapor nyob rau hauv cov hlab rau ib puag ncig; qhov zoo dua luminous efficiency ntawm LEDs kuj ua rau cov khoom ntau zog-txuag.

Raws li TFT-LCD txheej txheem thev naus laus zis, ua siab tawv tawg rau hauv dej hiav txwv xiav ntawm cov vaj huam sib luag
Daim duab 4 (a) Daim duab 4 (b) Daim duab 4.3D thiab qhov nce ntawm cov ntawv thov tshiab xws li kov vaj huam sib luag
Kev lag luam LCD tam sim no tau dhau los ua cov kev hloov pauv tseem ceeb, los ntawm kev nrhiav cov khoom loj hauv yav dhau los mus rau kev txhim kho cov kev sib tw tseem ceeb ntawm kev lag luam thiab cov nqi ntxiv ntawm cov khoom. Tau ntsib nrog qhov xwm txheej tshiab, Xunrui yog raws li kev paub ntawm thaj chaw loj TFT cov txheej txheem tsim khoom nyob rau hauv pem hauv ntej theem, thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob rov qab-kawg tsav thiab opto-mechanical tsim thiab sib dhos. Nws yog maj mam npaj thiab nrawm raws li TFT-LCD txheej txheem thev naus laus zis. Paub txog 10 xyoo tom ntej ntawm kev lag luam vaj huam sib luag. Qhov kev hloov pauv ntawm lub vaj huam sib luag no suav nrog 3D (Daim duab 4(a)), kov vaj huam sib luag (Daim duab 4(b))... thiab lwm yam. ntawm cov ntawv thov tshiab; Qhov kev teeb tsa ntawm cov thev naus laus zis tshiab yog kev txhim kho txuas ntxiv ntawm cov organic teeb pom kev zoo-emitting diodes (OLED), daim teb emission E-daim ntawv thiab lwm yam khoom siv thev naus laus zis.
