Thaum xaiv cov ntsuas lossis lub laptop, cov lus nug feem ntau tshwm sim los saib seb qhov twg yog qhov screen matrix los xaiv: IPS, TN lossis VA. Tsis tas li, nyob rau hauv cov yam ntxwv ntawm cov khoom muag, muaj ob qho tib si sib txawv ntawm cov kev sib tw no, xws li UWVA, PLS lossis AH-IPS, kuj tseem muaj cov khoom lag luam uas tsis tshua muaj nrog cov thev naus laus zis xws li IGZO.
Hauv qhov kev tshuaj xyuas no - txhua yam hais txog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, hais txog qhov twg zoo dua: IPS lossis TN, tej zaum VA, thiab tseem vim li cas cov lus teb rau cov lus nug no tsis yog ib txwm muaj. Saib ntxiv: USB Hom-C thiab Thunderbolt 3 Cov Khoom Taw Qhia, Matte lossis Glossy Screen - Qhov twg zoo dua?
IPS vs TN vs VA - cov sib txawv loj
Yuav pib nrog, qhov sib txawv loj ntawm cov sib txawv ntawm cov hom xaus: IPS (Hauv Dav Hlau Hloov Mus), TN (Twist Nematic) thiab VA (nrog rau MVA thiab PVA - Ntsug Kev Ncaj Ncees) siv hauv kev tsim cov ntxaij vab tshaus rau saib thiab khoos phis tawm rau cov neeg siv khoom kawg.
Kuv nco ntsoov ua ntej tias peb tab tom tham txog qee qhov "ntsuas" qhov tseem ceeb ntawm txhua hom, vim tias, yog tias koj coj cov lus qhia tshwj xeeb, tom qab ntawm ob IPS cov ntxaij vijtsam qee zaum yuav txawv dua li nruab nrab IPS thiab TN, uas peb tseem yuav tham txog.
- TN matrices yeej los ntawm teb lub sijhawm thiab kev tshuaj ntsuam tus nqi rov: Feem ntau cov ntxaij vab tshaus nrog lub sijhawm teb ntawm 1 ms thiab zaus ntawm 144 Hz yog TFT TN, thiab yog li ntawd lawv feem ntau yuav rau kev ua si qhov twg parameter no tuaj yeem yog qhov tseem ceeb. IPS cov saib nrog qhov hloov siab ntawm 144 Hz twb tau muag, tab sis: lawv tus nqi tseem nce siab piv rau "IPS li niaj zaus" thiab "TN 144 Hz", thiab lub sijhawm teb tseem nyob rau 4 ms (tab sis muaj cov qauv sib cais qhov twg 1 ms tau tshaj tawm ) VA-cov ntsuas nrog lub siab ua kom zoo thiab lub sij hawm luv teb kuj tseem muaj, tab sis hauv qhov sib piv ntawm tus yam ntxwv no thiab tus nqi TN - hauv thawj qhov chaw.
- IPS muaj widest saib cov ces kaum thiab qhov no yog ib qho ntawm qhov tseem ceeb ntawm cov hom vaj huam sib luag, VA - hauv qhov chaw thib ob, TN - kawg. Qhov no txhais tau hais tias thaum koj saib lub vijtsam los ntawm sab, qhov tsawg kawg ntawm cov xim thiab lub teeb distortion yuav pom nyob rau ntawm IPS.
- Ntawm IPS matrix, nyeg, tshwm sim backlight teeb meem ntawm cov ces kaum los yog ntug ntawm qhov tsaus nti tom qab, saib ntawm sab los yog tsuas yog muaj lub zeem muag loj, kwv yees li hauv daim duab hauv qab no.
- Kev muaj xim muaj hlau - ntawm no, ntxiv, nyob rau nruab nrab, IPS yeej, ntawm qhov nruab nrab, xim gamut zoo dua TN thiab VA matrices. Yuav luag txhua qhov matrices nrog 10-ntsis xim yog IPS, tab sis tus qauv yog 8 me me rau IPS thiab VA, 6 khoom rau TN (tab sis tseem muaj 8-ntsis TN matrices).
- VA yeej hauv kev ua tau zoo sib piv: Cov matrices zoo dua thaiv lub teeb thiab muab cov xim dub sib sib zog nqus. Nrog rau kev hloov xim, lawv kuj nyob ntawm nruab nrab zoo dua TN.
- Nqi - Raws li txoj cai, nrog rau lwm cov yam ntxwv sib xws, tus nqi ntawm cov ntsuas lossis lub laptop nrog TN lossis VA matrix yuav qis dua nrog IPS.
Muaj lwm qhov sib txawv uas tsis tshua pom: piv txwv li, TN siv hluav taws xob tsawg dua thiab, tej zaum, qhov no tsis yog qhov tseem ceeb rau lub desktop PC (tab sis nws tuaj yeem ua qhov sib txawv rau lub laptop).
Dab tsi ntawm matrix zoo dua rau kev ua si, duab thiab lwm yam hom phiaj?
Yog tias qhov no tsis yog thawj qhov kev tshuaj xyuas uas koj nyeem ntawm cov ncauj lus sib txawv, tom qab ntawd nrog qhov muaj feem ntau koj tau pom qhov kev txiav txim siab:
- Yog tias koj yog tus twv txiaj twv txiaj, koj qhov kev xaiv yog TN, 144 Hz, nrog G-Sync lossis AMD-Freesync tshuab.
- Tus kws yees duab lossis duab ua yeeb yaj kiab, ua haujlwm nrog cov duab lossis tsuas yog saib cov yeeb yaj kiab - IPS, qee zaum koj tuaj yeem coj mus saib ze VA.
Thiab, yog tias peb coj qee qhov nruab nrab ntawm cov xeeb ceem, ces cov lus pom zoo raug. Txawm li cas los xij, ntau yam tsis nco qab txog ntau tus lej:
- Muaj qis-IPS matrices thiab TN zoo. Piv txwv li, yog tias peb piv MacBook Cua nrog TN-matrix thiab lub laptop pheej yig nrog IPS (nws tuaj yeem yog pob nyiaj Digma lossis Prestigio cov qauv, lossis qee yam zoo li HP Pavilion 14), peb yuav pom tias nyob hauv kev coj txawv txawv TN-matrix ua tau zoo dua koj tus kheej nyob rau hauv lub hnub, muaj qhov xim zoo tshaj plaws sRGB thiab AdobeRGB, pom lub kaum ntse ntse zoo nkauj. Thiab txawm hais tias, ntawm cov ces kaum loj, pheej yig IPS-matrixes tsis hloov xim, tab sis ntawm lub kaum sab xis qhov twg MacBook Cua TN-zaub pib invert, muaj twb pom me ntsis ntawm xws li IPS matrix (nkag mus rau hauv dub). Koj tuaj yeem ua tau, yog tias muaj, sib piv ob lub iPhones zoo ib yam - nrog lub vijtsam qub thiab hloov chaw suav hauv Suav: ob qho IPS, tab sis qhov sib txawv yooj yim pom tau.
- Tsis yog txhua tus neeg siv khoom lub zog ntawm cov ntxaij vab tshaus laptop thiab lub koos pij tawj soj ntsuam ncaj qha nyob ntawm cov cuab yeej technology uas siv hauv kev tsim cov LCD matrix nws tus kheej. Piv txwv li, qee tus neeg tsis nco qab txog qhov ntsuas tshwj xeeb zoo li qhov ci ci: lawv tau txais lub siab ncaj ncees 144 Hz saib nrog qhov tshaj tawm ci ntsa iab ntawm 250 cd / m2 (qhov tseeb, yog tias nws ua tiav, nws tsuas yog nyob hauv nruab nrab ntawm lub vijtsam) thiab pib tawm, tsuas yog ntawm kaum sab xis rau saib , hom phiaj zoo tshaj hauv chav tsaus. Txawm hais tias, tej zaum nws yuav zoo dua kom txuag tau qee qhov nyiaj, lossis nres ntawm 75 Hz, tab sis cov vijtsam ci ntsa iab.
Raws li qhov tshwm sim: nws tsis yog ib txwm ua tau los muab cov lus teb meej, tab sis dab tsi yuav zoo dua, tsom mus rau tsuas yog hom ntawm kev sib luag thiab kev siv tau. Lub luag haujlwm loj yog ua si los ntawm pob nyiaj txiag, lwm yam tshuaj ntsuam tus yam ntxwv (qhov ci ci, kev daws teeb meem, thiab lwm yam) thiab txawm tias lub teeb pom kev zoo hauv chav uas nws yuav siv. Sim ua tib zoo xaiv koj txoj kev xaiv ua ntej thiab kawm txog kev txheeb xyuas, tsis txhob cia siab rau kev tshuaj xyuas "IPS ntawm TN nqe" lossis "Qhov no yog qhov pheej yig 144 Hz."
Lwm hom ntawm hom matrices thiab cim
Thaum xaiv saib xyuas lossis lub laptop, ntxiv rau cov qauv siv tshwj xeeb xws li matrices, koj tuaj yeem nrhiav pom lwm tus uas tsis muaj cov ntaub ntawv tsawg dua. Ua ntej tshaj plaws: txhua hom ntawm cov ntxaij uas tau sib tham saum toj no tuaj yeem muaj TFT thiab LCD qauv, vim tias lawv txhua tus siv cov kua siv lead ua kua thiab ib qho ua kom muaj kev sib ua.
Ntxiv mus, hais txog lwm txoj kev xaiv rau kev cim cia uas koj tuaj yeem hla:
- PLS, AHVA, AH-IPS, UWVA, S-IPS thiab lwm tus - ntau yam kev hloov kho ntawm IPS thev naus laus zis, feem ntau zoo sib xws. Qee ntawm lawv yog, qhov tseeb, IPS cov npe lag luam ntawm qee cov tuam ntxhab (PLS - los ntawm Samsung, UWVA - HP).
- SVA, S-PVA, MVA - kev hloov kho ntawm VA-panels.
- IGZO - Ntawm kev muag koj tuaj yeem nrhiav cov saib, ntxiv rau cov khoos phis tawm nrog lub lev loj, uas tau tsim ua IGZO (Indium Gallium Zinc Oxide). Cov ntawv luv tsis hais tag nrho txog hom kev sib dhos (qhov tseeb, hnub no nws yog IPS vaj huam sib luag, tab sis nws tau npaj los siv thev naus laus zis rau OLED ib yam nkaus), tab sis hais txog hom thiab khoom siv ntawm cov transistors siv: yog tias nyob rau hauv cov ntxaij vab tshaus zoo li nws yog aSi-TFT, tom qab no yog IGZO-TFT. Cov txiaj ntsig zoo: cov transistors yog pob tshab thiab muaj ntau qhov me me, vim li ntawd: lub siab zog thiab kev lag luam ntau dua qub (aSi transistors block ib feem ntawm lub ntiaj teb).
- OLED - thaum tsis muaj ntau tus saib zoo li no: Dell UP3017Q thiab ASUS ProArt PQ22UC (tsis muaj ib qho twg muag hauv Lavxias Federation). Qhov txiaj ntsig tseem ceeb yog cov xim dub tiag tiag (cov diodes tau muab tua, tsis muaj lub teeb pom kev tom qab), yog li qhov zoo sib xws siab heev tuaj yeem yog ntau dua li tsis muaj cov qauv. Qhov tsis zoo: tus nqi, kuj yuav ploj mus raws sijhawm, thaum lub thev naus laus zis rau kev saib xyuas khoom yog tseem hluas, yog li ntawd cov teeb meem tsis tau muaj peev xwm ua tau.
Kuv vam tias kuv tuaj yeem teb qee cov lus nug txog IPS, TN, thiab lwm yam kev kawm tiav, kos cov lus nug ntxiv, thiab pab kuv ua tib zoo xaiv cov kev xaiv.
