Yuav ua li cas xaiv txoj cai 7 nti LCD npo rau koj qhov project

Ib qho piv txwv tiag: tsis ncaj ncees lawm specs, nkim cov qauv, ncua kev tso tawm

Ntau tus engineers xaj cov qauv raws li qhov loj me thiab tus nqi, tsuas yog tshawb pom tom qab tias qhov ci ntsa iab tsis txaus rau kev siv sab nraum zoov, qhov cuam tshuam tsis zoo rau lawv lub mainboard, lossis lub kov vaj huam sib luag tsis ua haujlwm hauv hnab looj tes. Qhov tshwm sim? Lub hlis ncua thiab ntau txhiab nyiaj nkim.

Dab tsi feem ntau cov neeg yuav khoom saib thaum lawv pib yuav khoom

Feem ntau tsom rau tus nqi thiab kev daws teeb meem thaum tsis quav ntsej txog yam tseem ceeb xws li kev ua haujlwm kub, backlight lifespan, thiab ntev -lub sijhawm muaj.

Qhov kev qhia no yuav pab tau koj li cas rau thawj zaug

Kab lus no coj koj los ntawm kev txiav txim siab zoo- ua cov txheej txheem kom koj tuaj yeem ntseeg siab xaiv qhov zoo tshaj plaws 7 nti TFT LCD zaub nrog kov npo.

Sab hauv vs sab nraum zoov siv: vim li cas ib puag ncig hloov txhua yam

Cov ntawv thov sab hauv tuaj yeem siv tus qauv 300–500 nits ci ntsa iab, thaum sab nraum zoov lossis siab - ib puag ncig lub teeb xav tau 800–1500+ nits nrog tiv thaiv - glare coatings.

Handheld, vaj huam sib luag -mounted, lossis embedded? Form factor tseem ceeb

Cov cuab yeej siv tes yuav tsum muaj lub teeb yuag thiab qis - lub zog cov ntxaij vab tshaus, thaum lub vaj huam sib luag - mounted industrial units ua qhov tseem ceeb ntawm kev ruaj khov thiab kev xaiv mounting.

Leej twg yuav ua haujlwm rau nws - cov neeg siv khoom, cov kws tshaj lij, lossis cov tshuab?

Cov neeg siv khoom tau txais txiaj ntsig los ntawm kev sib tw capacitive kov, thaum cov neeg siv khoom lag luam yuav xav tau hnab looj tes- tau txais kev tiv thaiv los yog rugged capacitive kov.

Cov peev nyiaj ntau thiab xaj ntim: qauv vs lag luam wholesale vs loj ntau lawm

Cov qauv xaj feem ntau raug nqi ntau dua rau ib chav. Lag luam wholesale 7 nti TFT LCD tus nqi poob qis ntawm 500+ daim.

Nkag siab txog Core Specs ntawm a7 nti TFT LCD zaub

Kev daws teeb meem piav qhia: 800 × 480 vs 1024 × 600 vs 1280 × 800

800 × 480 (WVGA): Haum rau kev sib txuas lus yooj yim thiab tus nqi -sensitive tej yaam num.

1024 × 600 (WSVGA): Qhov kev xaiv nrov tshaj plaws - muaj qhov pom tseeb zoo rau HMI thiab ntau yam xov xwm.

1280 × 800+: Qhov zoo tshaj plaws rau siab - cov duab nthuav dav thiab cov ntawv thov hwm.

Brightness (nits): dab tsi txaus rau koj ib puag ncig?

250-400 nits ua haujlwm sab hauv tsev. Xaiv 700+ nits rau ib nrab- sab nraum zoov thiab 1000–1500 nits rau hnub ci ncaj qha.

Qhov sib piv piv thiab xim qhov tob - lawv puas tseem ceeb rau koj cov ntaub ntawv siv?

Kev sib piv siab dua (1000:1+) muab cov duab zoo dua . 16.7M xim (8-ntsis) yog tus qauv rau feem ntau ntawm kev lag luam thiab cov neeg siv khoom siv.

Saib lub kaum ntse ntse: TN vaj huam sib luag vs IPS vaj huam sib luag ntawm 7 nti npo

TN panels yog pheej yig dua tab sis muaj lub kaum ntse ntse. IPS versions muab 178℃saib - tsim nyog tus nqi ntxiv rau cov haujlwm niaj hnub no.

Resistive kov - tseem cuam tshuam rau xyoo 2024 thiab yog vim li cas

Resistive kov ua haujlwm nrog txhua yam khoom (stylus, hnab looj tes, cwj mem) thiab tseem nrov hauv kev lag luam thiab chaw kho mob.

Capacitive kov - thaum nws tsim nyog tus nqi ntxiv

Projected capacitive (PCAP) muaj ntau yam - kov thiab kev paub zoo dua rau cov neeg siv khoom thiab niaj hnub HMI daim ntawv thov.

Hnab looj tes-tus phooj ywg thiab stylus- sib haum rau kev siv hauv kev lag luam

Cov hnab looj tes tshwj xeeb-mode capacitive lossis hybrid cov kev daws teeb meem muaj rau cov chaw ua haujlwm.

Optical bonding vs air gap - qhov pom qhov txawv yog dab tsi?

Kev sib txuas kho qhov muag txo qhov kev xav thiab txhim kho kev ua haujlwm ntev thiab qhov sib txawv loj dua piv rau cov huab cua ib txwm muaj- qhov sib txawv.
