LCD module

Makhalidwe aukadaulo

LCM ndi chinthu chophatikizika kwambiri cha LCD poyerekeza ndi galasi.Kwa ang'onoang'ono -kakulidweChiwonetsero cha LCD, LCM ikhoza kukhala yabwino kulumikiza ma microcontrollers osiyanasiyana (monga makina a single -chip);komabe, pakuwonetsa kwakukulu kapena mtundu wa LCD, nthawi zambiri Imakhala ndi gawo lalikulu lazachuma kapena osatha kuwongolera dongosolo.Mwachitsanzo, 320 × 240 256 mtundu LCM ikuwonetsedwa mu masewera 20/sekondi (ndiko kuti, 20 nthawi 1 sekondi, 20 nthawi), ndipo deta imafalitsidwa kokha mu sekondi imodzi Kuchuluka kwake ndi: 320 × 240 × 8 × 20 = 11.71875MB kapena 1.465MB.Ngati muyezo MCS51 mndandanda single -chip microcomputer kukonzedwa, poganiza mobwerezabwereza ntchito malangizo MOVX mosalekeza kusamutsa deta izi, ganizirani mawerengedwe adiresi nthawi, osachepera 421.875mHz mawotchi akhoza kumalizidwa kumaliza Kutumiza deta kumasonyeza kuchuluka kwa deta. kukonza.

Kusamala popinda Konzani ndimeyi

LCD modulendi gawo lomwe limasonkhanitsa zida za Shanghai LCD ndikuwongolera, kuyendetsa dera ndi bolodi la PCB.Iye akhoza mwachindunji kulumikiza kompyuta.Mukamagwiritsa ntchito gawoli, kuwonjezera pa kusamala mukamagwiritsa ntchito chipangizo chowonetsera LCD, chiyeneranso kusonkhanitsidwa.Samalani zinthu zotsatirazi mukamagwiritsa ntchito:

Chithandizo choteteza filimu

Pali filimu yotetezera pamwamba pa chipangizo chotsirizidwa cha LCD pa gawo loyikapo kuti lisawonongeke pamwamba pa zokongoletsera.Osavumbulutsa asanafike kumapeto kwa msonkhano wa makina, kuti musawononge kapena kuipitsa malo owonetsera.

Pad

Ndikwabwino kukhazikitsa pedi pafupifupi 0.1mm pakati pa gawo ndi gulu lakutsogolo.Gululi liyeneranso kukhala lathyathyathya.Zimatsimikiziridwa kuti sizimapanga zosokoneza pambuyo pa msonkhano.Ndipo sinthani magwiridwe antchito a seismic.

Kuletsa mwamphamvu magetsi osasunthika

The ulamuliro ndi galimoto dera mu gawo ndi otsika -voltage ndi yaying'ono-mphamvu CMOS mabwalo, amene mosavuta analowerera ndi electrostatic, ndi thupi la munthu nthawi zina umatulutsa ochepa mkulu -voltage malo amodzi magetsi magetsi magetsi magetsi electrostatic, kotero mu ntchito, msonkhano, ndi ntchito mu ntchito Samalani kupewa static magetsi mosamalitsa.potengera izi:

1) Musakhudze chiwongolero chakunja ndi manja anu, bokosi lozungulira ndi zitsulo pa bolodi la dera.

2) Ngati mukuyenera kulumikizana mwachindunji, sungani gawo la thupi la munthu kukhala lofanana kapena kuyika thupi la munthu bwino.

3) Chitsulo chazitsulo chomwe chimagwiritsidwa ntchito powotcherera chiyenera kukhala chokhazikika bwino popanda kutayikira.

4) Chingwe chamagetsi chogwiritsira ntchito ndi zida zina ziyenera kukhala zokhazikika popanda kutayikira.

5) Osagwiritsa ntchito vacuum vacuum cleaner poyeretsa.Chifukwa imapanga magetsi olimba osasunthika.

6) Mpweya wouma udzatulutsanso magetsi osasunthika.Choncho, chinyezi cha chipinda chogwirira ntchito chiyenera kukhala pamwamba pa RH60%.

7) Zotsutsa ziyenera kupangidwa pakati pa nthaka, benchi yogwirira ntchito, mpando, alumali, ngolo, ndi zida zosungiramo zomwezo, apo ayi magetsi osasunthika adzapangidwanso.

8) Mukachotsa kapena kubwerera ku chikwama choyikamo kapena malo osunthira, samalani kuti musapange magetsi osasunthika.Osasintha kapena kusiya zolongedza zoyambira momwe mwafunira.

Kuwonongeka kosasunthika ndikuwonongeka kosasinthika.Onetsetsani kuti mumvetsere osati kusamala.

Chenjezo pa nthawi ya msonkhano.

Moduleyo idapangidwa mwaluso ndikusonkhanitsidwa.Osachikonza mwakufuna ndikuchikonza.

1) Bokosi lachitsulo silingathe kumangidwa mwakufuna ndikuphwanyidwa.

2) Musati kusintha mawonekedwe a bolodi PCB pa chifuniro, anasonkhana mabowo, mizere ndi zigawo zikuluzikulu.

3) Osasintha zomatira zomatira.

4) Musasinthe bulaketi iliyonse yamkati.

5) Osakhudza, kugwa, pindani, kupotoza gawolo.

kuwotcherera

Mu gawo lakuwotcherera lakunja ndi mawonekedwe ozungulira, ntchitoyo iyenera kuchitidwa motsatira njira zotsatirazi.

1) Kutentha kwa mutu wachitsulo cha soldering ndi zosakwana 280 ℃

2) kuwotcherera nthawi ndi zosakwana 3-4s

3) Kuwotcherera zinthu: wamba kristalo mtundu, otsika osungunuka.

4) Osagwiritsa ntchito kuwotcherera acidic.

5) Osapitirira 3 nthawi kuwotcherera mobwerezabwereza, ndipo nthawi iliyonse imafunika mobwerezabwereza kukhala mphindi 5 /

Kugwiritsa ntchito ndi kukonza ma modules

1) Pamene gawoli likugwiritsa ntchito mphamvu yofikira ndikuchotsa mphamvu, liyenera kuchitidwa mundandanda.Ndiko kuti, muyenera kulowa mulingo wazizindikiro pamagetsi abwino (5 ± 0.25V) kuti mulowe mulingo wazizindikiro.Ngati mulowa mulingo wazizindikiro mphamvu isanakhazikike, kapena mutatha kulumikizidwa, gawo lophatikizidwa mu gawoli lidzawonongeka ndipo gawoli lidzawonongeka.

2) Gawo la masanjidwe adontho ndi chida chowonetsera cha LCD chamsewu waukulu.Kusiyanitsa kowonetsera, kawonedwe kawonedwe ndi kutentha, ndi magetsi oyendetsa galimoto amagwirizana kwambiri.Choncho, ziyenera kusinthidwa mpaka kusiyana kopambana ndi kawonedwe.Ngati VEE ndi yokwera kwambiri, sizidzangokhudza zowonetsera, komanso zimakhudza moyo wa chipangizo chowonetsera.

3) Mukamagwiritsa ntchito malire otsika a kutentha kwa ntchito, kuyankha kumakhala kochepa kwambiri.Pamene malire apamwamba a kutentha kwa ntchito amagwiritsidwa ntchito, mawonekedwe onse owonetsera adzakhala akuda.Izi sizikuwonongeka.Kutentha kwa kutentha kumatha kubwerera mwakale.

4) Dinani gawo lowonetsera ndi mphamvu, zomwe zidzatulutse chiwonetsero chachilendo.Malingana ngati mphamvuyo yadulidwa, ikhoza kubwezeretsedwanso mwa kupezanso.

5) Pamene madzi kristalo anasonyeza chipangizo kapena pamwamba pa gawo ndi chifunga, musagwire ntchito, chifukwa electrode mankhwala poyankha zidzachitika pa nthawi iyi kupanga kusagwirizana.

6) Zithunzi zotsalira zogwiritsidwa ntchito kwa nthawi yayitali padzuwa ndi kuwala kwamphamvu.

Kusungirako gawo

Ngati kusungidwa kwa nthawi yayitali (monga zaka zingapo), timalimbikitsa njira zotsatirazi.

1) Ikani thumba la polyethylene (makamaka anti-static zokutira) ndikusindikiza pakamwa.

2) Kusungirako pakati pa -10-+35 ° C.

3) Ikani mumdima kuti mupewe kuwala kwamphamvu.

4) Osayika zinthu zilizonse pamwamba.

5) Pewani kwambiri kusungirako kutentha kwambiri / chinyezi.Iyenera kusungidwa pansi pamikhalidwe yapadera.Itha kusungidwanso pa 40 ° C, 85% RH, kapena 60 ° C ndi zosakwana 60% RH, koma zisapitirire maola 168.
