2.76 Round TFT LCD Module

ENH-TV2830MIPIKev piav qhia

 

Kuv khiav engineering ntawm ib qho me me - mus rau - nruab nrab LCD Hoobkas uas tau xa ntau tshaj 6,000 units ntawm2.76 Round TFT LCD Modulenyob rau hauv lub xyoo dhau los ib leeg. Qhov no 480 × 480 ncig zaub nrog MIPI interface thiab ST7701SN tus tsav tsheb tau dhau los ua ib qho ntawm peb feem ntau thov -tab sis tsis yog vim li cas kuv xav tau.

Thaum peb xub pib qhov qauv no, kuv xav tias cov ntsiab lus muag yuav pom tseeb: 480 × 480 daws teeb meem, IPS dawb saib lub kaum ntse ntse, MIPI interface. Tab sis cov lus nug uas khaws cia los ntawm cov neeg siv khoom tau hais meej dua: "Dab tsi yog qhov tseeb pixel suab?" "Kuv tus tswv tsev MIPI puas ua haujlwm nrog ST7701SN?" "Kuv puas tuaj yeem tau txais qhov no ua lub pob qhov rooj teb?" Cov lus teb tsis yog tag nrho hauv cov ntaub ntawv.

Cia kuv qhia qhov peb tau kawm los ntawm kev tsim thiab xa cov zaub no.

Qhov "dawb" Saib lub kaum sab xis tsis pub dawb-Nws yog Engineered

Lub spec hais tias "Saib Kev Qhia: Dawb." Qhov ntawd yog IPS thev naus laus zis nrog 85/85/85/85-degree saib cov ces kaum. Tab sis ntawm no yog dab tsi cov ntaub ntawv tsis hais txog: lub polarizer tseem muaj qhov pom kev zoo. Yog tias koj mount cov zaub upside down txheeb ze rau qhov axis, koj poob txog 30% ntawm qhov sib txawv ntawm cov ces kaum heev.

Peb nrhiav tau qhov no thaum ib tus neeg siv khoom siv smartwatch yws tias lawv cov zaub zoo li ntxuav tawm thaum cov neeg siv qaij lawv lub dab teg. Qhov teeb meem tsis yog cov zaub -nws yog qhov kev taw qhia mounting. Peb tig FPC tawm kev taw qhia nyob rau hauv lub tom ntej batch, thiab qhov teeb meem ploj lawm. Tam sim no peb suav nrog cov polarizer axis kos npe rau hauv txhua daim duab kos duab. Siv nws.

Vim li cas MIPI tseem ceeb dua li koj xav

Cov2.76 Round TFT LCD Modulesiv 1-txoj kab lossis 2-kab MIPI DSI interface, nyob ntawm qhov kev teeb tsa. Vim li cas MIPI tsis yog SPI lossis RGB? Ob qho laj thawj: bandwidth thiab tus pin suav.

Ntawm 480 × 480 daws teeb meem nrog 16.7M xim, tag nrho 60 fps refresh xav tau txog 138 Mbps ntawm cov ntaub ntawv dhau los. SPI tshaj tawm ib ncig ntawm 80 Mbps hauv kev xyaum. MIPI ua haujlwm yooj yim thaum siv 4-6 tus pins nkaus xwb. Sib piv qhov ntawd rau 24 tus pins rau ib qho RGB parallel interface. Rau cov qauv tsim thiab nqa tau yooj yim qhov chaw PCB nruj, qhov ntawd yog qhov hloov pauv kev ua si.

Ib tus neeg siv khoom tsim lub nplhaib ntse tau sim siv SPI- tsuas yog tso saib ua ntej. Lawv khiav tawm ntawm GPIOs ntawm lawv nRF52840 thiab yuav tsum tau ntxiv ib qho I/O expander. Hloov mus rau peb MIPI version tso tawm 18 tus pins. Qhov ntawd tsis yog qhov tshwj xeeb xwb - nws yog lub rooj tsav xwm txheej txheem yeej.

ST7701SN: Mature, Documented, thiab zam txim

ST7701SN tus tsav tsheb IC tau nyob ib puag ncig ntev txaus uas nws qhov kev xav tau nkag siab zoo. Qhov tseeb yog qhov zoo. Qhov kev pib ua ntu zus yog ruaj khov. Daim ntawv qhia kev sau npe yog sau tag nrho. Thiab cov tsim ua - hauv GRAM tshem tawm qhov xav tau rau sab nraud thav duab buffers.

Tab sis ib yam uas cov ntaub ntawv yuav tsis qhia rau koj: ST7701SN yog picky txog lub hwj chim - nce sequencing. Peb tau pom cov neeg siv khoom tsim tsis tau vim tias lawv siv VDDI (I / O voltage) ua ntej VCI (analog voltage). Peb cov qauv pob suav nrog lub zog pom zoo- daim duab qhia lub sijhawm. Ua raws nraim li nws, thiab koj yuav txuag koj tus kheej ib lub lim tiam ntawm kev debugging.

Rotary Knob Revolution

Ib qho ntawm feem nthuav daim ntawv thov peb twb pom rau lub2.76 Round TFT LCD Moduleyog lub pob qhov rooj teb zaub -ib qho ntse module integrating lub cev encoder nrog lub siab - txhais lus ncig. Cov khoom lag luam tawm tshiab no tau hloov pauv li cas cov neeg siv cuam tshuam nrog cov khoom siv, los ntawm lub rooj teeb rau lub tsheb dashboards.

Qhov 2.76-inch loj yog qhov tshwj xeeb zoo- haum rau daim ntawv thov no. Ntawm 70.13mm active cheeb tsam txoj kab uas hla, nws yog loj txaus los qhia qhov kub thiab txias curves, ntim qib, los yog cov zaub mov xaiv, tab sis compact txaus kom haum rau lub chav ua noj countertop los yog ib lub tsheb qhov chaw console. Qhov kev daws teeb meem 480 × 480 ua kom cov ntawv nyeem thiab cov duab nyob twj ywm ntse txawm tias pom los ntawm lub kaum sab xis me ntsis-uas tshwm sim tas li nrog cov pob qhov rooj.

Peb tau xa ntau pua chav rau cov neeg siv khoom tsim lub tshuab kas fes ntse, ntsuas cua sov, thiab kev tswj hwm huab cua hauv tsheb. Cov lus tawm tswv yim tau zoo ib yam: kev sib xyaw ntawm lub cev sib hloov thiab puv - xim IPS zaub ua rau cov neeg siv nkag siab qhov kev paub uas cov touchscreens tsis sib xws.

Lub Pixel Pitch nthuav dav tsis muaj leej twg hais txog

Lub pixel suab ntawm no module yog 0.1497mm kab rov tav thiab 0.1462mm vertically. Qhov asymmetry yog txhob txwm. RGB ntsug kab txaij kev npaj txhais tau hais tias subpixels siab dua lawv qhov dav, uas ua kom zoo dua cov ntawv nyeem hauv kev taw qhia portrait. Rau cov lus qhia ncig, qhov no tseem ceeb vim tias feem ntau UIs tso cov ntawv nyeem raws kab kab rov tav.

Yog tias koj tab tom tsim lub ntsej muag saib nrog cov ntawv sau hnub me me lossis cov pob qhov rooj nrog cov ntawv cim, koj yuav txaus siab rau qhov nthuav dav no. Qhov zoo pixel ceev yog hais txog 170 PPI-ntse txaus rau 6-point ntawv ntawm caj npab ntev.

Ob peb Nyuaj- Tau Txais Tus lej

Module qhov ntevLoj: 73.03 × 76.48 × 2.3 mm. Qhov chaw ua haujlwm yog 70.128 × 70.128 mm. Nco ntsoov me ntsis asymmetry nyob rau hauv daim ntawv qhia-FPC ntxiv txog 3 hli ntawm ib sab.

Ua haujlwm kub: -20℃rau +70℃. Cia: -30℃rau +80℃. Peb tau sim 100 units ntawm +70℃rau 72 teev. Tsis muaj flicker, tsis muaj xim hloov.

Backlight: 4 dawb LEDs nyob rau hauv parallel. Txuj ci ci 300-450 nits, customizable mus txog 1000+ nits.

Qhov sib piv piv: 1200:1 typical. Feem ntau - hom dub txhais tau tias muaj tseeb dub thaum pixels tawm - tseem ceeb rau kev nyeem sab nraum zoov.

Qhov hnyav: Hauv qab 10 grams. Peb hnyav 50 units los ntawm peb pawg. Qhov hnyav tshaj plaws yog 8.2g.

Dab tsi peb tuaj yeem hloov kho tiag tiag

Vim peb yog lub Hoobkas, tsis yog tus xa khoom, "kev cai" txhais tau tias peb hloov cov kab ntau lawm. Nov yog qhov peb tau ua rau cov neeg siv khoom tiag:

FPC ntev thiab tawm kev taw qhia: Los ntawm 15mm mus rau 150mm. Ib tus neeg siv khoom xav tau 120mm tus Tsov tus tw kom ncav cuag lub rooj tsav xwm tseem ceeb ntawm sab nraud ntawm lub cuab yeej kho mob.

Kov vaj huam sib luag: Capacitive (PCAP) nrog FT3267 lossis CST826 controllers, lossis tiv thaiv kov. Ntxiv txog 0.6mm thickness. Yam tsawg kawg nkaus xaj 1,000 units rau kev sib koom ua ke.

Npog iav: Tempered nrog anti- glare thiab anti- ntiv tes txheej, los yog txhob lo lo ntxhuav- luam ntawv logos.

Brightness: Txheem 300-450 nits. High-brightness versions txog 1000 nits rau kev siv sab nraum zoov.

Interface: MIPI yog tus qauv. RGB parallel (40 pins, 3SPI+18RGB) kuj muaj.

Kev txiav txim yam tsawg kawg nkaus rau cov qauv qauv yog 1,000 daim. Cov qauv txiav txim (1-5 daim) ib txwm nyob rau hauv Tshuag nrog tus nqi nominal, refundable tiv thaiv kev txiav txim ntau lawm. Cov cuab yeej kev cai feem ntau siv sijhawm 3-4 lub lis piam.

Kev xav zaum kawg

Cov2.76 Round TFT LCD Moduletsis yog qhov khoom pheej yig tshaj plaws nyob rau hauv khw. Tab sis nws yog ib qho uas ua haujlwm muaj kev ntseeg siab thoob plaws ntau yam ntawm cov ntawv thov-los ntawm dab teg- hnav khaub ncaws rau tsheb dashboards mus rau cov khoom siv hauv chav ua noj ntse. MIPI interface muab koj cov bandwidth koj xav tau yam tsis muaj tus lej suav koj tsis ua. Tus tsav tsheb ST7701SN yog tus paub tab thiab zoo -cov ntaub ntawv. Thiab lub kaum sab xis saib dawb txhais tau tias koj cov neeg siv yuav pom cov zaub kom meej meej ntawm txhua qhov kev taw qhia.

Order coj mus kuaj. Kuaj lawv hauv koj lub qhov rooj tiag tiag. Hu rau peb yog tias muaj qee yam tsis zoo. Peb tau kawm ntau yam los ntawm kev xa khoom ntau txhiab tus qauv no, thiab peb zoo siab los qhia qhov peb paub.
