Ob peb yam tiag tiag tsim nyog tham txog ntawm no 1.6-nti puag ncig LCD

Cia peb pib nrog qhov loj me . 1.6 nti kab pheeb ces kaum - nws yog qhov chaw qab zib rau cov lus qhia puag ncig. Tsis loj, tsis me dhau. Koj tau txais thaj chaw nquag txaus los qhia cov ntaub ntawv tseem ceeb, tab sis nws tsis yuam koj cov khoom kom loj. Hom zaub yog tus qauv TFT-LCD, active matrix, txhua pixel tsav ntawm nws tus kheej. Tsis muaj dab tsi zoo nkauj, tab sis nws yog tus paub tab, txhim khu kev qha, teb sai, thiab muab qhov zoo sib xws rau koj.

Kev daws teeb meem yog qhov uas nws tau nthuav tawm . 400 × 400 pixels hauv lub voj voog 1.6-nti ua haujlwm tawm mus txog 350 PPI. Qhov ntawd txhais li cas hauv lub neej tiag? Koj tuaj yeem tso me me 6-point font ntawm lub vijtsam thiab tseem nyeem nws yam tsis muaj pixelation. Peb tau sim nws nrog cov ntawv me me thiab lub ntsej muag saib lub ntsej muag - cov npoo yog ntse, tsis muaj jaggies. Xim qhov tob yog 16.7M, uas yog 8-ntsis RGB. Gradients zoo li du, tsis muaj qhov pom tseeb banding.

Saib lub kaum sab xis yog teev raws li "Txhua". Qhov ntawd txhais tau hais tias IPS lossis cov cuab yeej dav dav zoo sib xws. Peb tau rub cov qauv random tawm ntawm cov kab ntau lawm thiab saib lawv los ntawm sab saum toj, hauv qab, sab laug, sab xis - xim thiab ci ntsa iab tuav zoo. Qhov sib piv zoo sib xws yog siab dua 800: 1. Brightness yog feem ntau ntawm 300 thiab 500 cd / m². Yog tias koj qhov project xav tau ntau dua, peb tuaj yeem thawb nws - peb tau ua 1000 cd / m² ua ntej.

Tam sim no lub mechanical sab. Qhov loj me: 45.89mm × 42.94mm × 0.9mm. Qhov ntawd suav nrog cov tsav tsheb Circuit Court thiab cov hlau bezel, yog li koj tuaj yeem siv cov lej no ncaj qha rau koj qhov kev txiav tawm vaj tsev thiab tsim kev tsim kho.

Qhov chaw cia dav dav tsis yog tus lej xwb: xav txog cov thawv ntim khoom ci hauv qab lub hnub ci. Qhov tseem ceeb tshaj plaws.

 

 

Vim li cas 1.6 Round TFT LCD Module tau dhau los ua Peb Feem Ntau Nug-Hais Txog Zaub Xyoo no

Kuv tseem nco ntsoov thawj zaug uas tus neeg siv khoom nug peb txog 1.6-nti puag ncig TFT nrog MIPI interface. Nws yog lub smartwatch pib, thiab lawv twb sim peb lwm tus neeg muag khoom. Lawv qhov kev tsis txaus siab yeej ib txwm zoo ib yam: "Cov duab puag ncig zoo li zoo nyob rau hauv cov ntaub ntawv, tab sis ib zaug peb tsav nws ntawm 60fps, lub interface chokes, lossis lub kaum sab xis saib ua rau cov npoo zoo li ntxuav tawm." Qhov kev sib tham ntawd tau thawb peb los saib tob rau hauv qhov ua tau ua rau lub voj voog me me ua haujlwm hauv lub ntiaj teb tiag tiag, tsis yog ntawm daim ntawv xwb.

Lub module uas thaum kawg daws lawv qhov teeb meem yog dab tsi peb tam sim no hu ua1.6 Hloov TFT LCD Module. Tab sis ua ntej kuv nkag mus rau hauv vim li cas nws ua haujlwm, cia kuv qhia ob peb yam uas feem ntau cov nplooj ntawv spec yuav tsis qhia koj txog qhov loj thiab hom.

Qhov kev sib tw zais ntawm 400 × 400 ntawm lub voj voog 1.6-nti

Ntawm daim ntawv, 400 × 400 daws teeb meem hauv 1.6-nti kab pheeb ces kaum suab zoo nkauj - thiab nws yog. Lub pixel ntom ntom saum toj 350 PPI, uas yooj yim rau hauv "retina" thaj chaw. Koj tuaj yeem muab 6-point font ntawm qhov no thiab tseem nyeem nws yam tsis muaj squinting. Tab sis ntawm no yog dab tsi engineers tsis paub txog thaum lawv sim nws: tsav 160,000 pixels nyob rau hauv lub voj voog yuav tsum tau ceev faj tuav ntawm cov ces kaum. Daim duab plaub yog qhov yooj yim - koj tsuas yog luam theej duab kab los ntawm kab. Ib puag ncig zaub xav tau ib lub voj voos kheej kheej lossis kev sib tw nruj hauv tus tsav tsheb. Ntau tus nqi pheej yig round modules siv SPI lossis QSPI, thiab lawv stutter lub sijhawm koj sim ua kom zoo nkauj saib tes hla lub dial.

Tias yog vim li cas peb xaiv tus tsav tsheb ST7797 rau qhov no1.6 Hloov TFT LCD Module. ST7797 tsis yog tus neeg tsav tsheb pheej yig tshaj plaws ntawm kev ua lag luam, tab sis nws muaj ob qhov tseem ceeb rau cov lus qhia puag ncig: lub GRAM loj sab hauv uas tuaj yeem daws qhov chaw nyob tsis muaj tus tswv-sab clipping, thiab haiv neeg MIPI DSI kev txhawb nqa. MIPI muab koj cov bandwidth tiag tiag - peb tab tom tham cov ntaub ntawv txuas ntxiv uas tso cai rau koj thawb puv npo 60fps cov yeeb yaj kiab yam tsis muaj kua muag lossis cov thav duab poob. Ib tug ntawm peb cov neeg muas zaub tau sim nws nrog ib tug complex ob txhais tes cheb animation ntawm ib tug FreeRTOS system, thiab lub CPU load poob los ntawm ze li ntawm 40% piv rau lawv yav dhau los QSPI-raws li module. Qhov ntawd yog qhov txawv qhov tsim nyog interface ua.

Yog vim li cas "Txhua lub kaum sab xis" tseem ceeb rau cov ntxaij vab tshaus

Ib qho duab plaub feem ntau yog saib head-on. Ib puag ncig zaub - tshwj xeeb tshaj yog ntawm smartwatch lossis pob qhov rooj - yog saib los ntawm txhua lub kaum ntse ntse. Koj qaij koj lub dab teg, koj saib ntawm sab, koj ntsia nws thaum tsav tsheb. Feem ntau IPS vaj huam sib luag tau lees paub qhov pom dav dav, tab sis hauv kev xyaum, ntau tus neeg raug kev txom nyem los ntawm kev hloov daj lossis qhov sib piv poob qis dua 70 degrees. Peb tau khiav qhov kev sim yooj yim ntawm peb cov qauv tsim: peb ntsuas qhov ci thiab xim hloov ntawm 80 degrees hauv tag nrho plaub kab pheeb ces kaum. Cov1.6 Hloov TFT LCD Modulenyob hauv ΔE ntawm tsawg dua 3, uas yog qhov pom kev tsis pom kev rau cov neeg feem coob. Qhov ntawd tsis yog hmoov zoo - nws yog vim peb tau ua haujlwm nrog cov neeg muag khoom vaj huam sib luag los kho cov kua siv lead ua kom sib haum tshwj xeeb rau kev txiav tawm. Qhov chaw ua haujlwm yog 39.84 × 39.84mm, thiab pixel suab yog li 0.1mm, tab sis cov khoom siv kho qhov muag siv cov yeeb yaj kiab them nyiaj uas koj yuav tsis pom nyob rau hauv generic square panels.

Lub thickness 0.9 hli yog qhov ntxiab yog tias koj tsis ceev faj

Kuv pom ntau tus tsim khoom tsim tau zoo siab txog 0.9mm tag nrho cov tuab (tsis suav rov qab thiab FPC). Thiab yog, qhov ntawd yog qhov nyias nyias - nws tso cai rau koj tsim lub nplhaib ntse lossis cov khoom siv kho mob me me uas tsis muaj pob. Tab sis ntawm no yog qhov tseeb: 0.9mm iav substrate yog qhov tsis yooj yim yog tias koj lub tshuab mounting tsis suav rau nws. Peb tau muaj cov neeg siv khoom uas tau sim ua cov kua nplaum ncaj qha rau lub vaj tsev yas, tsuas yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, peb tau txiav txim siab los ua tus kws kho mob). Peb cov kev daws teeb meem tsis yog ua kom lub khob tuab dua (uas yuav kov yeej lub hom phiaj), tab sis muab cov khoom xaiv stainless hlau stiffeners ntawm FPC thiab ua npuas ncauj gasket uas absorbs poob siab. Qhov ntawd yog hom kev nthuav dav koj tsuas yog kawm tom qab tsim ob peb puas txhiab units. Peb nyob ntawm ntau tshaj 200,000 units xa mus rau daim ntawv foos no, thiab tus nqi tsis ua haujlwm los ntawm cov neeg kho tshuab kev ntxhov siab tam sim no qis dua 0.1%.

Real-world thermal kev ua tau zoo

Cov ntaub ntawv hais tias -20℃rau +70℃kev khiav hauj lwm, -30℃rau +80℃cia. Cov lej no yog kev saib xyuas - peb tau sim ib pawg rau -30℃kev ua haujlwm (paub rau) thiab +85℃cia rau 240 teev. Tus neeg tsav tsheb ST7797 khaws lub sijhawm kaw, thiab cov kua siv lead ua kua tsis pom muaj kev puas tsuaj mus tas li. Tab sis dab tsi cov ntaub ntawv tsis qhia koj yog tias MIPI interface yog qhov ua siab ntev dua ntawm qhov kub thiab txias impedance hloov dua li RGB sib npaug. Hauv ib txoj haujlwm tsheb, tus neeg siv khoom PCB muaj qhov ntev, tsis zoo sib xws MIPI kab (tshaj 80mm yam tsis muaj kev tswj xyuas kom zoo). Hauv chav tsev kub, nws ua haujlwm zoo. Ntawm 65 degree, daim duab lub qhov muag kaw, thiab cov zaub pib qhia random flickers. Peb pab lawv rov taug txoj kev sib txawv ntawm khub thiab ntxiv ib qho kev sib koom ua ke - daws teeb meem. Qhov ntawd yog hom kev txhawb nqa uas koj tau txais thaum koj ua haujlwm nrog lub Hoobkas uas tau nkag siab cov txheej txheem siab ceev, tsis yog lub tuam txhab lag luam xwb.
