1. Cov ntaub ntawv dab tsi tsis qhia koj txog cov Specs

Cov1.54-nti Square LCD Zaub Moduleyog tsim nyob ib ncig ntawm 240 × 240 IPS vaj huam sib luag. Ntawm 1.54 nti kab pheeb ces kaum, uas ua haujlwm tawm mus rau kwv yees li 220 PPI. Rau kev sib piv, 1.3-nti 240 × 240 screen yog hais txog 260 PPI - tab sis qhov ntxiv 0.24 ntiv tes kab pheeb ces kaum txhais tau hais tias 1.54-nti version yog qhov yooj yim nyeem rau cov neeg uas muaj qhov muag pom. Ib tus neeg siv khoom ua tus neeg saib xyuas kev noj qab haus huv tau hloov pauv los ntawm 1.3 mus rau 1.54 ntiv tes tshwj xeeb vim tias lawv cov neeg siv ntsuas tau yws txog qhov muag pom.

Lub square 1: 1 nam piv - 27.7mm × 27.72mm active cheeb tsam - tsis yog ib tug gimmick. Peb sim ib lub vaj huam sib luag 240 × 320 nyob rau hauv tib lub hnab ntawv tshuab. Qhov tshwm sim: nkim qhov chaw ntawm ob sab thiab ib qho UI uas xav tias muaj teeb meem. Nrog lub square, koj tau txais tag nrho 27.7mm nyob rau hauv ob qho tib si kev taw qhia. Tias yog vim li cas daim ntawv square tau dhau los ua tus qauv de facto rau round-watch-face displays, txawm tias qhov chaw ua haujlwm yog square - lub ntsej muag puag ncig zaum hauv nws, thiab cov ces kaum ntxiv tau muab zais los ntawm bezel.

IPS saib lub kaum ntse ntse.Lub spec hais tias 80℃nyob rau hauv tag nrho cov lus qhia. Qhov ntawd txhais tau li cas hauv kev xyaum: thaum tus neeg siv saib ntawm lub smartwatch los ntawm 45℃dab teg qaij, qhov sib piv tsis thim rov qab. Peb tau sim nws sab-los-sab nrog TN vaj huam sib luag; qhov txawv yog ua yeeb yam. Rau lub dashboard mounted saum lub qhov muag (zoo li lub tsheb lub hauv paus zaub), IPS yog qhov yuav tsum tau - cov neeg ua haujlwm pom lub vijtsam hauv qab.

ST7789V2 tsav tsheb.Cov nti no tau nyob ib ncig ntawm xyoo, uas yog vim li cas peb siv nws. Tsis zoo li cov tsav tsheb tshiab nrog ib nrab-ci pib ua ntu zus, ST7789V2 cov lus txib tau sau tseg rau qhov ncua sij hawm kawg. Lub on-chip GRAM tuav tag nrho 240 × 240 thav duab, yog li tsis xav tau RAM sab nraud. Peb tau pom cov neeg nyiam nyiam tsav cov zaub no nrog 8-pin ESP-01S - koj tsis tuaj yeem ua qhov ntawd nrog cov zaub sib luag.

Peb LEDs nyob rau hauv parallel.Vim li cas parallel tsis yog series? Vim tias qhov hluav taws xob rau pem hauv ntej ntawm cov LEDs dawb yog nyob ib ncig ntawm 3.0V. Ib qho 3.3V lossis 5V cov khoom siv tuaj yeem tsav peb qhov sib npaug ntawm cov LEDs nrog ib tus resistor. Series yuav xav tau 9V, uas yuav xav tau lub zog hloov pauv. Parallel kuj muab redundancy: yog tias ib qho LED tsis qhib, ob qho tib si tseem teeb. Cov neeg siv khoom tsim cov khoom siv kho mob roj teeb tshwj xeeb tau thov rau qhov no tom qab tus neeg sib tw series-LED zaub poob ib nrab ntawm nws qhov ci los ntawm ib qho LED tsis ua haujlwm.

Nws txiav qhov cuam tshuam los ntawm lub teeb chaw ua haujlwm thiab hnub ci - qhov tseem ceeb rau cov khoom siv sab nraum zoov. Cov txheej glossy ntsej muag lub teeb nraub qaum, ua kom lub teeb kis tau yooj yim. Qhov sib piv yog 900-1000: 1. Peb ntsuas qhov no nrog Konica Minolta CS-200; nws tsis yog marketing fluff.

1.9 hli thickness.Qhov no yog tag nrho qhov siab ntawm module, suav nrog FPC stiffener tab sis tsis yog FPC thickness. Rau ib lub smartwatch, uas yog nyias txaus kom tawm hauv chav rau 400-500mAh roj teeb. Qee cov neeg siv khoom tau thov rau 1.5mm - peb tuaj yeem ua qhov ntawd los ntawm kev tshem tawm cov stiffener, tab sis tom qab ntawd FPC yuav tawg. Peb pom zoo 1.9mm rau cov khoom siv thiab 2.0mm rau kev lag luam siv.

2. Qhov twg peb tau pom Cov Zaub no ua haujlwm tiag tiag

Peb tsis tsuas yog sau cov ntawv thov - peb tau xa mus rau cov neeg siv khoom tiag tiag:

Smartwatches thiab qoj trackers.Ib tug me nyuam 'smartwatch cov neeg siv khoom siv 1.54-nti square vaj huam sib luag vim nws haum rau lawv tus qauv saib cov ntaub ntawv tsim.

Industrial handheld terminals.Tus tsim cov cuab yeej ntsuas ntsuas xav tau lub vijtsam uas ua haujlwm ntawm -20℃mus rau +70℃. Peb tau sim 100 units ntawm +70℃rau 72 teev - tsis muaj flicker, tsis muaj xim hloov. Lawv tso 5,000-unit order.

kas fes tshuab.Cov chaw tsim khoom siv tshuab espresso muab 1.54-nti square zaub rau hauv lub pob qhov rooj. Tus neeg siv tig lub pob qhov rooj los xaiv cov zaub mov txawv, thiab qhov screen qhia qhov ntsuas kub. Lub voj voog UI haum zoo kawg nkaus hauv thaj chaw ua haujlwm square.

DIY & kev kawm.Tus neeg muag khoom STEM siv cov qauv no nrog ESP32. Lawv xaiv nws vim tias ST7789V2 tau txais kev txhawb nqa los ntawm TFT_eSPI lub tsev qiv ntawv tawm ntawm lub thawv - tsis tas yuav sau cov tsav tsheb qis.

Ib daim ntawv thov uas ua rau peb xav tsis thoob: ib tus neeg siv khoom tsim lub oscilloscope portable nrog cov zaub no. 240 × 240 daws teeb meem yog siab txaus los qhia 200-point waveform nrog cov kab sib txuas nyeem tau. Tsis yog qhov peb tsim nws rau, tab sis nws ua haujlwm.

3. Peb tau kawm dab tsi txog Customization

Peb yog lub Hoobkas, tsis yog tus xa khoom. Thaum koj nug txog tej yam kev cai, peb yeej hloov cov kab ntau lawm.

FPC kev cai- Tus qauv FPC yog 24-pin, 0.5mm suab, hauv qab tawm. Peb tau ua tiav sab-tawm FPCs rau cov nplhaib ntse, cov tails ntev (txog 200mm) rau cov khoom siv uas lub ntsiab PCB nyob deb ntawm cov zaub, thiab txawm tias kev cai kub ntiv tes rau ZIF txuas los ntawm cov npe tshwj xeeb. Tooling yuav siv sij hawm 3-4 lub lis piam thiab nqi txog 800-800-1500 nyob ntawm qhov nyuaj.

Kov vaj huam sib luag kev koom ua ke- Peb ntxiv capacitive kov siv FT3267 lossis CST816 controllers. Ntxiv thickness: ~ 0.6mm. Ib tus neeg siv khoom tsim lub iav ntse tswj vaj huam sib luag xav tau kev sib txuas kho qhov muag kom tshem tawm qhov sib txawv ntawm huab cua - uas txhim kho lub hnub ci nyeem tau li ntawm 40% tab sis ntxiv ob lub lis piam rau lub sijhawm. Yam tsawg kawg nkaus rau kev kov yog 1,000 units.

Npog iav- Tempered iav nrog anti-glare (AG) los tiv thaiv tus ntiv tes (AF) txheej. Peb kuj tau ua silk-screened logos thiab ciam teb. Kev cai iav tooling yuav siv sij hawm 4-5 lub lis piam.

Brightness- Tus qauv yog 400 cd / m². Qhov ntawd yog qhov zoo rau kev siv sab hauv. Rau ib tug handheld ntaus ntawv siv sab nraum zoov, peb muab ib tug 1000 cd / m² version. Nws siv tib yam peb LEDs tab sis nrog ib qho sib txawv optical zaj duab xis pawg thiab ib tug nruj dua LED tam sim no (tseem 20mA ib LED, tab sis cov zaj duab xis yog ntau npaum). 1000 nits version raug nqi li ntawm 15% ntau dua.

Interface- 4-xaim SPI yog tus qauv. Peb kuj tau ua 3-xaim SPI rau tus pin-txheej tsim, thiab 8-ntsis MCU sib npaug rau cov txheej txheem qub qub uas tsis muaj SPI. Txhua qhov kev hloov pauv yuav tsum muaj tus tsav tsheb sib txawv IC teeb tsa thiab kev ua haujlwm sib cais.

Ua haujlwm kub- Tus qauv yog -20℃rau +70℃. Rau tsheb lossis khoom siv sab nraum zoov, peb muab qhov txuas ntxiv ntawm -30℃rau +80℃. Qhov no yuav tsum tau hloov cov kua dej LCD (dav kub nematic) thiab cov nplaum polarizer. Cov ntawv txuas ntxiv ntxiv txog 10% rau tus nqi module.

Yam tsawg kawg nkaus txiav txim kom muaj nuj nqis- Standard modules: 1,000 daim. Kev cai modules: 3,000 daim (tab sis peb tuaj yeem sib tham rau kev sim ua haujlwm). Qauv: 1-5 daim ib txwm nyob hauv Tshuag. Tus nqi coj mus kuaj yog nominal thiab tag nrho rov qab los ntawm kev txiav txim ntau lawm.

4. Ob peb tus lej uas tsis yog lag luam Fluff

Contrast ratio:900-1000: 1. Tsis yog 2000: 1. Qhov ntawd yog ncaj ncees.

Brightness:400 cd/m² UAS. Tsis yog 800 tshwj tsis yog tias koj them rau qhov kev xaiv siab brightness.

Kev siv lub zog:Logic 10-15 mA ntawm 3.3V. Backlight 60 mA ntawm 3.0V. Kev pw tsaug zog qis dua 10 µA.

Lub neej ua haujlwm:Backlight ntsuas 20,000 teev tas li (rau 50% ci ntsa iab). Qhov ntawd yog hais txog 8 xyoo ntawm 8-teev-ib-hnub siv - ntau tshaj li txaus rau cov neeg siv khoom.

FPC flex lub neej:1,000 cycles ntawm 5mm radius. Peb kuaj txhua batch nrog lub motorized flex tester.

5. Qhov yuam kev peb tau ua (Yog li koj tsis tas yuav)

Qhov yuam kev # 1: Piv txwv tias tag nrho ST7789V2 pib ua ntu zus yog tib yam.Lawv tsis yog. Qhov kev txiav txim ntawm cov lus txib thiab ncua sij hawm tom qab pw tsaug zog tawm hais kom ua tseem ceeb. Peb muab cov kev txheeb xyuas pib ua tiav hauv C rau STM32 thiab Arduino. Luam nws raws nraim. Ib tus neeg siv khoom sim "ua kom zoo" qhov kev ncua sijhawm thiab xaus nrog cov zaub uas khov tom qab ob peb feeb. Rov qab mus rau peb cov cai kho nws.

Qhov yuam kev #2: Muab FPC stiffener ze ze rau txoj kab khoov.Cov khoom thaum ntxov muaj lub stiffener pib tsuas yog 1 hli ntawm qhov tawm. Cov neeg muas zaub folding FPC mus rau hauv nruj wearables tawg kab. Peb rov tsim dua tshiab nrog 5mm kev nyab xeeb margin thiab tam sim no sim txhua pawg ntawm 5mm radius flex.

Qhov yuam kev #3: Tsis quav ntsej txog 0.02mm active cheeb tsam asymmetry.Qhov chaw ua haujlwm yog 27.7mm dav thiab 27.72mm siab. Qhov 0.02mm sib txawv los ntawm pixel suab (0.115mm vs 0.1155mm). Nws tsis pom qhov muag, tab sis ib tus neeg siv khoom siv tshuab ntsuas nws nrog micrometer thiab ntshai. Peb tam sim no teev nws meej meej kom tsis txhob muaj kev ntxhov siab.
