Raws li qhov tseem ceeb hauv cov khoom siv hluav taws xob, IPS TFT LCD zaub tau dhau los ua ntau theem tseem ceeb ntawm kev hloov pauv thev naus laus zis. Raws li ib feem tseem ceeb ntawm TFT-LCD thev naus laus zis, IPS ua tiav cov duab pom dav dua thiab cov xim muaj tseeb dua los ntawm kev tsim tshwj xeeb ntawm cov kua siv lead ua kua molecules. Cov khoom tseem ceeb ntawm cov cuab yeej siv tshuab no tsim kom muaj qhov tseeb, txhua feem ua lub luag haujlwm tseem ceeb.
Lub backlight module ua lub zog rau IPS TFT LCD zaub system, feem ntau muaj xws li LED teeb bar, lub teeb qhia phaj, thiab cov yeeb yaj kiab kho qhov muag. Txias cathode fluorescent teeb tau dav siv nyob rau theem pib, tab sis tam sim no, cov LEDs dawb yog lub teeb pom kev zoo. Lub teeb qhia phaj hloov cov kab teeb ci rau hauv qhov chaw teeb pom kev zoo, siv cov txheej txheem ua tiav microstructures kom ua tiav cov teeb pom kev zoo sib xws. Multilayer optical films-xws li diffusers, prism films, thiab reflective films- ua hauj lwm ua ke los txhim kho brightness uniformity thiab ua kom lub teeb siv efficiency ntau tshaj 60%.
Cov kua siv lead ua kua yog lub hauv paus nruab nrab ntawm cov khoom siv thev naus laus zis, tsim los ntawm cov khoom siv ua kua siv lead ua sandwiched ntawm ob lub polarizers. Cov yam ntxwv tseem ceeb ntawm IPS thev naus laus zis yog tias cov kua siv lead ua kua molecules tig mus rau lub dav hlau substrate, uas yog qhov txawv ntawm cov qauv TN. Lub dielectric thiab optical anisotropy tsis tau ntawm cov kua siv lead ua kua ncaj qha cuam tshuam lub sij hawm teb thiab kev sib piv. Spacers tuav qhov sib txawv ntawm tes ntawm 5 txog 7 microns, uas yog kwv yees li ib -feem kaum ntawm txoj kab uas hla ntawm tib neeg cov plaub hau.
TFT array substrate yog lub plawv ntawm kev tsav tsheb matrix, muaj ntau lab tus nyias - zaj duab xis transistors. Txhua pixel yog tswj los ntawm TFT hloov, feem ntau yog ua los ntawm amorphous silicon lossis polycrystalline semiconductor cov ntaub ntawv. Luam theej duab kab thiab cov ntaub ntawv kab tsim ib qho orthogonal matrix, ua kom cov kab nce qib -los ntawm - kab scanning. ITO pixel electrodes yog qauv nrog micrometer precision, thiab kev tswj ntawm ntug serration ncaj qha cuam tshuam rau cov zaub uniformity. LTPS thev naus laus zis txhawb kev txav hluav taws xob mus rau ntau dua 100 cm² / V·s, txhawb kev daws teeb meem siab dua thiab cov nqi tshiab.
Cov xim lim substrate yog ua raws nraim nrog TFT substrate los ua kom tiav cov kua siv lead ua cell. RGB tri- xim mosaic kev npaj yog cov qauv pixel ntau tshaj plaws, thaum qee cov khoom siv sib xyaw ua ke dawb subpixels los txhim kho qhov ci. Cov matrix dub thaiv lub teeb xau ntawm pixels, thiab nws qhov aperture piv ncaj qha cuam tshuam rau vaj huam sib luag transmittance. Spherical spacers xyuas kom meej qhov sib nrug ntawm ob lub substrates thaum zam qhov chaw ua haujlwm.
Lub voj voog tsav tsheb ua raws li "lub hlwb" ntawm lub vaj huam sib luag, suav nrog lub sijhawm tswj xyuas, tus tsav tsheb, thiab lub rooj tsav tsheb ICs. Cov chips no tau sib txuas ncaj qha mus rau lub iav substrate siv COG (Chip-On- iav) thev naus laus zis. Qhov tseeb ntawm cov ntaub ntawv tsav hluav taws xob nce mus txog 8 cov khoom lossis ntau dua, thiab Gamma nkhaus kev kho kom haum 256-theem greyscale tswj. Nrog rau kev txais yuav ntau dua ntawm Mini LED backlighting, hauv zos dimming algorithms yuav tsum tswj cov kev tswj hwm kev ywj pheej rau ntau txhiab thaj chaw, tso cov kev xav tau siab dua ntawm cov tsav tsheb ICs.
Touchscreen modules tau nce ntau hauv IPS vaj huam sib luag, nrog cov cuab yeej siv hluav taws xob ua haujlwm yog qhov kev xaiv tseem ceeb. Lub kov sensor muaj ntau txheej txheej ntawm ITO cov qauv, ua tiav kev tshawb pom qhov tseeb txog li 1 hli. Nyob rau hauv - xov tooj ntawm tes kov technology integrates lub sensor nyob rau hauv lub kua siv lead ua cell, ho txo module thickness. Kov ICs txheej txheem capacitance variation signals los ntawm ntau pua txoj kev, ua tiav cov ntaub ntawv tshaj tawm txog li 120 Hz los xyuas kom meej kov cov lus teb.
Cov yam ntxwv ntawm cov khoom muab kev txhawb nqa txhua yam rau qhov precision optoelectronic system. Cov hlau backplate ua haujlwm rau ob qho tib si cua sov dissipation thiab cov txheej txheem kev ua haujlwm, nrog kev sib txawv ntawm qhov sib txawv ntawm 0.1 mm / m². Lub thav duab yas nta ib snap- ntawm kev tsim rau kev sib dhos sai thiab tiv thaiv electromagnetic. Cov ntawv luam tawm yooj yim txuas cov qauv ua haujlwm, thiab lawv cov impedance txuam cuam tshuam rau siab -ceev teeb liab kis tau zoo. Anti- plua plav daim kab xev foob ntug qhov khoob kom tiv thaiv cov khoom txawv teb chaws los ntawm kev cuam tshuam kev ua haujlwm kho qhov muag.
Raws li kev siv thev naus laus zis, cov khoom ntawm IPS TFT LCD cov lus qhia txuas ntxiv mus. Oxide semiconductor TFTs thawb pixel ceev tshaj 800 PPI, thiab yees duab- cov txheej txheem sib dhos hloov kho tshuab rubbing rau cov kua siv lead ua kom meej dua. Cov kev tsim kho tshiab no ua rau IPS panels txuas ntxiv thawb cov ciam teb ntawm cov xim raug, cov lus teb ceev, thiab lub zog ua haujlwm, ua kom lawv txoj haujlwm hauv kev lag luam zaub.
