Cov cim LCD zaub modules (COB)
Thaum lub sij hawm tsim khoom, peb muab qhov tseem ceeb ntawm cov khoom lag luam muaj nyob hauv kev ua lag luam, feem ntau hu ua cov khoom lag luam. Cov npe qauv npe rau cov cim LCD zaub modules hauv Suav LCD manufacturers suav nrog:
8 x 2 LCD:
0802A-14, 0802A-16, nrog 14 thiab 16 tus pins, feem.
yog ib qho 8x2 cim LCD module.Nws siv COB (Chip on Board) thev naus laus zis los ntim cov tsav tsheb ncaj qha rau ntawm lub rooj tsavxwm hauv qab, yog li nws muaj kev tsim qauv tsim thiab ruaj khov. Nws yog tsim los ntawm LCD + PCB + coj backlight + hluav taws xob Cheebtsam.
yog dot matrix LCD module tshwj xeeb uas siv los tso saib cov ntawv, cov ntsiab lus, cov cim, thiab lwm yam. Nws tau muab faib ua ob hom kev sib kis: 4-ntsis / 8-ntsis cov ntaub ntawv kis tau tus mob.Muab 5 × 7 dot matrix + cursor zaub hom. Muab cov ntaub ntawv tsis pub DDRAM, cim lub tshuab hluav taws xob CGROM thiab lub cim tsim hluav taws xob CGRAM. CGRAM tuaj yeem siv los khaws cov ntaub ntawv font txog li 8 5 × 8 dot matrix graphic cim uas koj txhais. Muab cov lus txib nplua nuj: cov zaub ntshiab; tus cursor rov qab mus rau keeb kwm; tso saib on/off; cursor rau / tawm; tso saib cim flashing; hloov tus cursor; display shift element, thiab lwm yam.
16 x 2 LCD:
1602A (ib tus pin tawm, sab hauv qab), 1602A-V3.0 (pin tawm, sab saum toj thiab hauv qab), 1602DB-V3.0 (ob tus pin tawm, sab laug).
16x2 LCDs muaj qhov sib xws, yog li koj tuaj yeem xaiv cov qauv uas haum rau koj cov kev xav tau zoo tshaj plaws raws li tus pin tso.
yog ib hom kua siv lead ua kua zaub module muaj peev xwm nthuav tawm ob kab txog li 16 cim txhua. Hom zaub no tau siv dav hauv cov tshuab kos, Arduino tej yaam num, thiab lwm yam kev siv microcontroller.
yog hais txog kev sib txuas ntawm LCD npo nruab nrog I2C (inter-kev sib txuas hauv Circuit Court, serial bus) interface, uas yooj yim heev rau kev sib txuas thiab tswj thiab tso cai rau ntau yam khoom siv sib txuas lus los ntawm tib cov ntaub ntawv kab.
16 x 4 LCD:
yog ib qho kev sib xyaw ua ke ntawm LCD zaub module, feem ntau yog siv rau hauv cov khoom siv uas xav tau kom pom ntau cov cim thiab cov ntaub ntawv.16 * 4 lcd zaub siv COB (Chip- ntawm-} Board) ntim tshuab los ua ke cov LCD zaub, tsav Circuit Court thiab tswj logic ntawm lub rooj tsav xwm hauv Circuit Court, nrog cov khoom siv zoo, kev sib koom ua ke thiab kev ruaj ntseg.
muaj 16- cim x 4-kab zaub qauv, muab cov ntaub ntawv nplua nuj thiab tsim nyog rau kev nthuav tawm ntau cov ntawv thiab cov ntaub ntawv. Nws feem ntau siv los ua tus nqi qis dua rau 12864 lub cim dot matrix npo.
Nws muab cov duab meej meej thiab pom dav dav ntawm tus nqi qis.
Txawm li cas los xij, nws tsis haum rau cov khoom siv me me uas muaj qhov chaw tsawg. Nws kuj tsis tuaj yeem ua cov duab hloov dua siab tshiab.
20x2 LCD npo
20x2 LCD zaub
Qhov no yog lub cim LCD module nrog lub pixel daws teeb meem ntawm 20 × 2. Lub 2002A LCD module yog ib lub npov ntev, duab plaub tsim los qhia cov ntawv luv luv. Tsis zoo li cov duab kos duab matrix, nws tsis tuaj yeem tso saib cov duab nyuaj lossis cov animations thiab tsuas yog siv tau rau cov duab digital xwb.
nrog 16 tus pin yog 2002A. Nws lub ntsiab lus interface yog tib yam li 1602A LCD. Yog tias koj xav tau lub LCD ntev dua li 1602A, xav txog 2002A.
20x4 LCD zaub:
yog lub cim LCD muaj peev xwm nthuav tawm 20 kab x 4 kab ntawm cov cim. Nrog rau qhov sib ntxiv ntawm I2C module, nws yuav tsum tsuas yog ob lub teeb liab kab (SCL thiab SDA) rau kev tswj, txo tus naj npawb ntawm IO ports ntawm microcontroller / Arduino. Qhov no tso cai rau lub LCD txuas nrog ntawm qhov chaw nres nkoj serial, es tsis yog qhov chaw nres nkoj ib txwm muaj.
Hom kev tshuaj ntsuam no tsuas tuaj yeem tso saib cov ntawv thiab cov cim, tsim nyog rau cov ntawv nyeem, thiab txhawb cov neeg siv - cov cim (piv txwv li, tso saib cov cim yooj yim).
Rau cov yeeb yam zoo li no, cov khoom lag luam A series qhia cov ntsiab lus sib xws thiab tsim nyog rau kev nthuav tawm cov ntaub ntawv. Lawv yog siv nyob rau hauv daim ntawv thov yooj yim nrog cov ntsiab lus ntawm cov cim txwv. Cov ntsiab lus interface ntawm cov khoom no yeej ib txwm zoo ib yam, tsuas yog qhov sib txawv me me. Peb tuaj yeem siv qhov loj los txiav txim siab seb lub vijtsam LCD twg yog qhov tsim nyog rau kev txhim kho, ua rau kev txhim kho yooj yim dua thiab raug nqi - zoo. Yog tias koj xav tau cov khoom lag luam no, thov hu rau peb - Tuam Tshoj Chengxin Optoelectronics Co., Ltd.!
