LCD module

Unyanzvi hunoita

LCM ndeyepamusoro yakabatanidzwa LCD chigadzirwa kana ichienzaniswa negirazi.Kune diki-saiziLCD kuratidza, LCM inogona kuve yakanakira kubatana kune akasiyana mamicrocontrollers (akadai senge -chip machines);zvisinei, kune yakakura-saizi kana ruvara LCD kuratidza, kazhinji Inotora chikamu chakati wandei chezviwanikwa kana kusakwanisa kudzora sisitimu yekutonga.Semuenzaniso, 320 × 240 256 ruvara LCM inoratidzwa mumitambo makumi maviri / yechipiri (kureva, ka20 mu1 sekondi, 20 nguva), uye data inofambiswa musekondi imwe chete Huwandu hwakakura se: 320 × 240 × 8 × 20 = 11.71875MB kana 1.465MB.Kana iyo yakajairwa MCS51 yakatevedzana imwe -chip microcomputer yakagadziriswa, uchifungidzira kuti kakawanda shandisa iyo MOVX kuraira kuti urambe uchiendesa iyi data, funga iyo kero kuverenga nguva, ingangoita 421.875mHz wachi inogona kupedzwa kupedzisa. processing.

Chengetedzo yekupeta Rongedza ndima iyi

LCD modulechinhu chinounganidza Shanghai LCD zvishandiso uye kutonga, kutyaira dunhu uye mutsetse bhodhi PCB.Anogona kubatanidza zvakananga kukombiyuta.Paunenge uchishandisa iyi modhi, mukuwedzera kune yekungwarira kana yakajairika LCD kuratidza mudziyo inoshandiswa, inofanirawo kuunganidzwa.Chenjerera kune zvinotevera zvinhu panguva yekushandisa:

Kurapa inodzivirira firimu

Pane firimu rinodzivirira riri pamusoro peyakapedzwa LCD mudziyo pane yakaiswa module kudzivirira pamusoro kubva pakushongedza.Usaizarura pamberi pekuguma kwemusangano wemashini, kuitira kuti usasvibisa kana kusvibisa nzvimbo yekuratidzira.

Pad

Zvakanakisa kuisa padhi inenge 0.1mm pakati pemodule nepaneri yekumberi.Iyo pani inofanirawo kuramba yakati sandara.Inovimbiswa kuti haibudisi kukanganisa mushure mekusangana.Uye kunatsiridza seismic kuita.

Kunyatsodzivirira static magetsi

Kudzora uye kutyaira dunhu mune module yakaderera-voltage uye micro-simba CMOS maseketi, ayo anopinzwa nyore ne electrostatic, uye muviri wemunhu dzimwe nguva unoburitsa mashoma akakwira-voltage static magetsi emagetsi emagetsi emagetsi emagetsi, saka mukushanda, gungano, uye shandisa mukushandisa Ngwarira kudzivirira static magetsi zvakasimba.kuti izvi zviitike:

1) Usagunzva kutungamira kwekunze nemaoko ako, dunhu nesimbi bhokisi pabhodhi redunhu.

2) Kana iwe uchifanira kubata zvakananga, chengetedza moduli yemuviri wemunhu zvakafanana kana kudzika muviri wemunhu zvakanaka.

3) Simbi inosungirira inoshandiswa pakutungidza inofanira kunyatsodzika pasi pasina kubuda.

4) Iyo inoshanda yemagetsi koni uye mamwe maturusi anofanirwa kuve akadzika pasi pasina kuvuza.

5) Usashandise vacuum vacuum cleaner pakuchenesa.Nekuti inoburitsa yakasimba static magetsi.

6) Mhepo yakaoma inoburitsawo magetsi akamira.Nokudaro, hunyoro hweimba yekushanda hunofanira kunge huri pamusoro peRH60%.

7) Anopikisa anofanirwa kuumbwa pakati pevhu, bhenji rebasa, chigaro, sherufu, ngoro, uye maturusi ekuchengetedza izvo zvakafanana, kana zvikasadaro magetsi emagetsi anogadzirwa zvakare.

8) Paunenge uchibvisa kana kudzoka kubhegi rekurongedza kana chinzvimbo chekufamba, chenjerera kuti usaite static magetsi.Usachinje kana kusiya zvekutanga kurongedza paunoda.

Kuparara kwakamira kukuvara kusingadzoreki.Iva nechokwadi chekuteerera uye kusava nehanya.

Kuchengetedza panguva yekushanda kwegungano.

Iyo module yakanyatsogadzirwa uye yakaunganidzwa.Usaite madiro woigadzirisa.

1) Bhokisi resimbi harigoni kusungwa pakuda uye kuparadzaniswa.

2) Usagadzirise chimiro chePCB board pamadiro, akaungana maburi, mitsetse uye zvikamu.

3) Usagadzirise iyo conductive adhesive bar.

4) Usagadzirise chero bhaketi remukati.

5) Usabate, kudonha, peta, shandura module.

welding

Mune yekunze welding module uye iyo interface yedunhu, kushanda kunofanirwa kuitwa zvinoenderana neanotevera maitiro.

1) Tembiricha yemusoro wesimbi inotengeswa ishoma pane 280 ℃

2) Welding nguva iri pasi pe3-4s

3) Welding zvinhu: yakajairika crystal mhando, yakaderera kunyungudika nzvimbo.

4) Usashandise acidic welding.

5) Usapfuure katatu kudzokororwa welding, uye nguva imwe neimwe inodzokororwa inodiwa kuve maminetsi mashanu/

Kushandiswa uye kuchengetedza ma modules

1) Kana iyo module inoshandisa simba rekuwana uye kubvisa simba, inofanira kuitwa muhurongwa.Ndokunge, iwe unofanirwa kupinda muyero yechiratidzo pane yakanaka magetsi ekupa (5 ± 0.25V) kuti upinde muyero yechiratidzo.Kana iwe ukapinda muyero wechiratidzo musati magetsi akasimba, kana mushure mekubviswa, dunhu rakabatanidzwa mumodule richakuvadzwa uye module ichakuvadzwa.

2) Iyo dot matrix module inzira huru -nhamba yeLCD kuratidza mudziyo.Musiyano wekuratidzira, maonero ekona uye tembiricha, uye magetsi ekutyaira ane hukama zvakanyanya.Nokudaro, inofanira kugadziriswa kusvikira yakanyatsosiyana uye maonero.Kana VEE yakakwira zvakanyanya, haizongokanganisa chiratidziro, asi zvakare inokanganisa hupenyu hwechigadzirwa chekuratidzira.

3) Paunenge uchishandisa muganho wakaderera weiyo tembiricha yekushanda, mhinduro inononoka.Kana iyo yekumusoro muganho weiyo tembiricha yekushanda ichishandiswa, iyo yese yekuratidzira nzvimbo inoshanduka dema.Izvi hazvina kukuvara.Iyo yekudzoreredza tembiricha renji inogona kudzoka kune yakajairika.

4) Dzvanya chikamu chekuratidzira nesimba, icho chinoburitsa chiratidziro chisina kujairika.Chero bedzi simba rakagurwa, rinogona kudzoserwa nekuwanazve.

5) Kana iyo yemvura crystal kuratidza mudziyo kana pamusoro peiyo module iri mhute, usashande kushanda, nekuti electrode kemikari mhinduro ichaitika panguva ino kuti ibudise kubviswa.

6) Mifananidzo yakasara yekushandiswa kwenguva refu muzuva uye chiedza chakasimba.

Module kuchengetedza

Kana kwenguva refu (yakadai seanopfuura makore mashoma) kuchengetedza, tinokurudzira nzira dzinotevera.

1) Isa homwe yepolyethylene (zvichida anti-static coating) uye isa chisimbiso muromo.

2) Kuchengeta pakati -10-+35 ° C.

3) Isa murima kuti udzivise chiedza chakasimba.

4) Usambofa wakaisa chero zvinhu pamusoro.

5) Kunyatsodzivirira kuchengetedza pasi pekupisa kwakanyanya / humidity mamiriro.Inofanira kuchengetwa pasi pemamiriro ezvinhu anokosha.Inogona zvakare kuchengetwa pa40 ° C, 85% RH, kana 60 ° C uye isingasviki 60% RH, asi haifanirwe kudarika 168 maawa.
