LCD module

Ibiranga tekinike

LCM nigicuruzwa kinini cya LCD ugereranije nikirahure.Kuri GitoyaLCD yerekana, LCM irashobora koroha cyane guhuza microcontrollers zitandukanye (nkimashini imwe-imashini);icyakora, kubunini-bunini cyangwa ibara LCD yerekana, mubisanzwe Bizatwara igice kinini cyibikoresho cyangwa ntibishobora kugenzura sisitemu yo kugenzura.Kurugero, 320 × 240 256 ibara LCM ryerekanwa mumikino 20 / isegonda (ni ukuvuga inshuro 20 mumasegonda 1, inshuro 20), kandi amakuru yatanzwe mumasegonda imwe gusa Umubare ni mwinshi nka: 320 × 240 × 8 × 20 = 11.71875MB cyangwa 1.465MB.Niba urutonde rusanzwe rwa MCS51 rukora -cip microcomputer itunganijwe, ukeka ko ukoresha inshuro nyinshi amabwiriza ya MOVX kugirango uhore wohereza aya makuru, tekereza igihe cyo kubara aderesi, byibuze amasaha 421.875mHz ashobora kurangira kugirango yuzuze Ihererekanyamakuru ryerekana umubare munini wamakuru gutunganya.

Icyitonderwa cyo Guhindura Hindura iki gika

LCD modulenikintu giteranya ibikoresho bya LCD bya Shanghai no kugenzura, gutwara ibizunguruka no kumurongo PCB.Arashobora guhuza mudasobwa.Iyo ukoresheje iyi module, usibye kwitondera mugihe ibikoresho rusange byerekana LCD byakoreshejwe, bigomba no guterana.Witondere ibintu bikurikira mugihe ukoresha:

Firime ikingira

Hano hari firime ikingira hejuru yicyuma cya LCD cyarangiye kuri module yashyizweho kugirango wirinde ubuso bwiza.Ntukabishyire ahagaragara mbere yuko iteraniro ryimashini rirangira, kugirango ritaba ubutaka cyangwa ngo ryanduze hejuru yerekana.

Pad

Nibyiza gushiraho padi hafi 0.1mm hagati ya module numwanya wimbere.Umwanya ugomba kandi kuguma neza.Bijejwe ko bidatanga kugoreka nyuma yo guterana.Kandi utezimbere imikorere yimitingito.

Irinde rwose amashanyarazi ahamye

Kugenzura no gutwara ibizunguruka muri module ni bike -voltage na micro-power ya CMOS, byinjira byoroshye na electrostatike, kandi umubiri wumuntu rimwe na rimwe ubyara ingufu nke-nini-nini cyane yumuriro w'amashanyarazi amashanyarazi amashanyarazi, kuburyo mubikorwa, guterana, kandi ukoreshe mukoresha Witondere gukumira amashanyarazi ahamye.Kuri iyi:

1) Ntugakore ku isasu ryo hanze ukoresheje amaboko yawe, umuzenguruko nicyuma ku kibaho cyumuzunguruko.

2) Niba ugomba guhura bitaziguye, komeza umubiri wumuntu module ubushobozi bumwe cyangwa hasi umubiri wumuntu neza.

3) Icyuma cyo kugurisha gikoreshwa mu gusudira kigomba kuba gihagaze neza nta kumeneka.

4) Umuyoboro wamashanyarazi ukora nibindi bikoresho bigomba kuba bihagaze neza nta kumeneka.

5) Ntugakoreshe vacuum vacuum kugirango usukure.Kuberako itanga amashanyarazi akomeye.

6) Umwuka wumye uzanatanga amashanyarazi ahamye.Kubwibyo, ubuhehere bwicyumba cyakazi bugomba kuba hejuru ya RH60%.

7) Hagomba gushyirwaho résistoriste hagati yubutaka, intebe yakazi, intebe, isanduku, igare, nibikoresho kugirango bigumane ubushobozi bumwe, naho ubundi amashanyarazi ahamye nayo azabyara.

8) Mugihe ukuyemo cyangwa usubiye mumufuka wapakira cyangwa umwanya wimuka, witondere kutabyara amashanyarazi ahamye.Ntugahindure cyangwa ngo utererane ibipapuro byumwimerere uko bishakiye.

Isenyuka rihamye ni ibyangiritse bidasubirwaho.Witondere kwitondera kandi ntubyiteho.

Kwirinda mugihe cyo guterana.

Module yateguwe neza kandi irateranijwe.Ntukayitunganyirize uko wishakiye kandi uyisane.

1) Agasanduku k'icyuma ntigashobora gufatwa uko bishakiye kandi karasenyutse.

2) Ntugahindure imiterere yubuyobozi bwa PCB uko bishakiye, ibyobo byegeranijwe, imirongo nibigize.

3) Ntugahindure akabari kayobora.

4) Ntugahindure imitwe yimbere.

5) Ntugakoreho, kugwa, kugundura, kugoreka module.

gusudira

Muri module yo gusudira yo hanze hamwe nu murongo wa interineti, ibikorwa bigomba gukorwa hakurikijwe inzira zikurikira.

1) Ubushyuhe bwumutwe wicyuma kiri munsi ya 280 ℃

2) Igihe cyo gusudira kiri munsi ya 3-4s

3) Ibikoresho byo gusudira: ubwoko bwa kristu isanzwe, ingingo yo gushonga.

4) Ntukoreshe gusudira aside.

5) Ntukarenge inshuro 3 zo gusudira inshuro nyinshi, kandi burigihe burigihe bikenerwa kuba iminota 5 /

Gukoresha no gufata neza module

1) Iyo module ikoresha imbaraga zo kugera no guhagarika imbaraga, igomba gukorwa muri gahunda.Nukuvuga ko, ugomba kwinjiza urwego rwibimenyetso kumashanyarazi meza (5 ± 0.25V) kugirango winjire murwego rwibimenyetso.Niba winjiye murwego rwibimenyetso mbere yuko amashanyarazi ahamye, cyangwa nyuma yo gutandukana, umuzenguruko uhuriweho muri module uzangirika kandi module izangirika.

2) Akadomo ka matrix module ni umuhanda -umubare LCD yerekana.Kugaragaza itandukaniro, impande zose hamwe n'ubushyuhe, hamwe na voltage yo gutwara irafitanye isano cyane.Kubwibyo, igomba guhindurwa kugeza itandukaniro ryiza nicyerekezo.Niba VEE iri hejuru cyane, ntabwo izagira ingaruka kumyerekano gusa, ahubwo izagira ingaruka kubuzima bwibikoresho byerekana.

3) Iyo ukoresheje imipaka yo hasi yubushyuhe bwakazi, igisubizo kiratinda cyane.Iyo imipaka yo hejuru yubushyuhe bwakazi ikoreshwa, ubuso bwose bwerekana bizahinduka umukara.Ibi ntabwo byangiritse.Ubushyuhe bwo gukira burashobora gusubira mubisanzwe.

4) Kanda igice cyo kwerekana n'imbaraga, bizatanga ibyerekanwa bidasanzwe.Igihe cyose amashanyarazi yaciwe, irashobora kugarurwa na re-gutsinda.

5) Mugihe igikoresho cyerekana ibintu byerekana ibintu cyangwa ubuso bwa module ni igihu, ntukore akazi, kuko igisubizo cya chimique ya electrode kizaba muriki gihe kugirango habeho gutandukana.

6) Amashusho asigaye yo gukoresha -igihe kirekire gukoresha izuba numucyo ukomeye.

Kubika Module

Niba uburebure -burebure (nkimyaka irenga mike) ububiko, turasaba inzira zikurikira.

1) Shyira umufuka wa polyethylene (byaba byiza urwanya anti-static) hanyuma ushireho umunwa.

2) Ububiko hagati ya -10- + 35 ° C.

3) Shyira mu mwijima kugirango wirinde urumuri rukomeye.

4) Ntuzigere ushyira ikintu icyo aricyo cyose hejuru.

5) Irinde rwose kubika munsi yubushyuhe bukabije / ubushuhe.Igomba kubikwa mubihe bidasanzwe.Irashobora kandi kubikwa kuri 40 ° C, 85% RH, cyangwa 60 ° C na munsi ya 60% RH, ariko ntigomba kurenza amasaha 168.
