Cog LCD 4wire SPI Interface Series

COG LCD Screen muaj qhov sib txawv zoo, pom kev pom zoo, thiab cov duab ruaj khov uas ua haujlwm rau ntau yam kev lag luam thiab cov neeg siv khoom siv hluav taws xob xav tau:

Hom zaub: tuaj yeem pom cov cim ASCII, cov cim tshwj xeeb, thiab cov duab kev cai hauv cov cim, duab, lossis cov duab sib xyaw.

Kev daws teeb meem thiab qhov loj me: Koj tuaj yeem xaiv los ntawm ntau qhov kev daws teeb meem thiab cov chaw tso saib, los ntawm cov ntxaij vab tshaus me me mus rau nruab nrab - loj tswj vaj huam sib luag, nyob ntawm seb daim ntawv thov xav tau dab tsi.

Xaiv ntawm ib qho LED lossis EL backlight, uas los ntawm ob peb xim thiab ci ntsa iab kom nyeem tau yooj yim dua.

Teb ceev: Lub nrawm nrawm nrawm yog qhov zoo rau kev hloov kho cov ntaub ntawv hauv lub sijhawm tiag tiag thiab nthuav tawm cov ntaub ntawv dynamic, uas ua rau lub interface ua haujlwm zoo.

Lub siab - qhov sib piv thiab cov zaub tsis tu ncua ua rau nws yooj yim pom cov ntaub ntawv thiab siv lub cuab yeej hauv cov teeb meem nyuaj.

Qhov txiaj ntsig tseem ceeb ntawm Chip- ntawm- iav LCD yog nws cov khoom ntim thiab cov qauv tsim:

Chip on Glass technology: Cov nti tswj tau txuas ncaj qha rau lub iav LCD, uas ua rau nws thinner dua thiab zoo dua rau lub teeb hluav taws xob.

Lub teeb yuag: COG siv chav tsawg dua li cov ntim COB thiab yooj yim kom haum rau hauv cov khoom siv me me.

Kev ntseeg tau: Nws tuaj yeem tswj kev vibrations thiab cuam tshuam zoo, ua rau nws zoo siv hauv cov chaw tsim khoom thiab ntawm cov khoom siv txawb.

Tsim los tiv thaiv: Qee cov qauv tuaj yeem kho kom muaj plua plav- pov thawj thiab tiv thaiv - zoo li qub, uas ua rau lawv kav ntev dua thiab ua haujlwm zoo dua.

Chip-on-Glass Display ua kom paub tseeb tias cov cuab yeej ua haujlwm zoo los ntawm kev ua kom zoo ntawm cov qauv ntim khoom. Qhov no kuj ua rau nws yooj yim rau nruab thiab koom ua ke cov cuab yeej.

COG Cim LCD muaj ntau hom kev sib tshuam uas tuaj yeem siv los txuas cov tshuab:

Hom kev sib txuas: Txhawb SPI, I2C, thiab kev sib txuas sib txuas (8-ntsis thiab 16-ntsis) ua haujlwm nrog ntau lub platform tswj.

Tau tshaj: Ua haujlwm nrog Arduino, STM32, Raspberry Pi, thiab lwm yam kev tswj hwm thawj zaug

Kev them nyiaj yug tsav tsheb: Ua tau -hauv lossis sib xws nrog cov khoom siv sib xws xws li ST7565, SSD1306, thiab HT1621. Lawv kuj tuaj nrog cov qauv code thiab cov ntaub ntawv hauv tsev qiv ntawv.

Ntau yam nta: Qee tus qauv siv tau ntau- npo cascading lossis cov txheej txheem ua qauv.

COG LCD Dis

kev ua si tuaj yeem teeb tsa tau yooj yim nyob rau hauv ntau hom kev teeb tsa thiab kev tswj hwm kev lag luam vim nws muaj ntau yam kev sib tshuam thiab sib xws nrog ntau lub tshuab sib txawv.

COG Graphic LCD ua haujlwm zoo nyob rau hauv ntau qhov chaw nyuaj:

Cov qauv qauv tuaj yeem ua haujlwm ntawm qhov kub ntawm -20 txog 70 degrees Celsius, thaum lub dav kub version tuaj yeem ua haujlwm ntawm qhov kub ntawm -30 txog 80 degrees Celsius.

Qhov ntsuas kub rau kev ruaj ntseg yog -30℃txog 85 degree.

Humidity thiab Kev Tiv Thaiv: Ua haujlwm rau cov kab ntau lawm thiab cov khoom siv txawb. Nws muaj kev tiv thaiv dej noo, tiv thaiv - kev kho zoo li qub, thiab dej tsis kam.

Kev tiv thaiv -kev co thiab tiv thaiv- cuam tshuam: xyuas kom nws ua haujlwm ruaj khov nyob rau lub sijhawm thiab thaum mus ncig

Vim tias nws tuaj yeem hloov mus rau qhov chaw sib txawv, COG LCD zaub yuav siv tau rau lub sijhawm ntev hauv kev lag luam automation, instrumentation, thiab sab nraum zoov hluav taws xob.

Q1: Dab tsi yog qhov txawv ntawm COG LCD thiab ib txwm LCD?
A: COG LCD ncaj qha txuas cov tswj nti rau lub iav vaj huam sib luag, nrog cov tuab tuab thiab me me ntim, haum rau cov khoom siv compact.
Q2: Puas yog nws muaj teeb pom kev zoo?
A: Yeem LED lossis EL backlight, customizable nyob rau hauv cov xim sib txawv thiab brightness, xyuas kom meej nyeem tau nyob rau hauv tsawg lub teeb los yog nyob rau hauv ib puag ncig.
Q3: Puas yog qhov sib cuam tshuam nrog Arduino / STM32?
A: Feem ntau cov qauv txhawb SPI / I2C / parallel interfaces thiab muab cov tsev qiv ntawv tsav tsheb thiab cov qauv qauv rau kev txhim kho sai.
Q4: Nws puas tuaj yeem hloov kho qhov loj thiab kev daws teeb meem?
A: Txhawb kev hloov kho ntawm qhov loj me, kev daws teeb meem, thiab cov ntsiab lus kom tau raws li qhov xav tau ntawm daim ntawv thov sib txawv.
Q5: Puas yog COG LCD haum rau kev lag luam ib puag ncig?
A: Yog lawm, koj tuaj yeem xaiv qhov ntsuas kub ntawm qhov dav, uas yog tiv thaiv kev co, tiv thaiv kev cuam tshuam, thiab tiv thaiv - zoo li qub, haum rau kev lag luam thiab siv sab nraum zoov.
