Nzira yekugadzirisa sei izvi zvinowanzoitika zvikanganiso zviduku?
Kutanga, gadzirira maturusi ekugadzirisa.Zvinhu zvishanu zvakakosha zveChiratidziro che LEDvashandi vanogadzira ma tweezers, hot air gun, soldering iron, multimeter, uye test card.Zvimwe zvekubatsira zvinosanganisira solder paste (waya), solder flux, waya yemhangura, glue, nezvimwe.
1、Nyaya yemakonye
"Caterpillar" ingori izwi redimikira, richireva chiitiko chetambo refu uye yakapenya inoonekwa pane mamwe ma LED ekuratidzira masikirini pasi pemamiriro emagetsi pasina chekuisa sosi, kazhinji mutsvuku.Mhedzisiro yechiitiko ichi kuvuza kwemukati chip chemwenje, kana kuti pfupi pfupi yeIC pamusoro wedunhu kuseri kwayo, neiyo yekare iri iyo yakawanda.Kazhinji, kana mamiriro ezvinhu aya aitika, tinongoda kubata pfuti yemhepo inopisa uye kuridza mhepo inopisa pamwe chete ne "caterpillar" yakasvibiswa iyo iri kubuda magetsi.Kana isu tikaifuridza kune dambudziko mwenje, zvinowanzoitika nekuti iyo yemukati leakage chip yekubatanidza yakatyoka nekuda kwekudziya, asi pachine njodzi yakavanzika.Isu tinongoda chete kutsvaga iyo inodonha ye LED bead uye toitsiva maererano nenzira yataurwa pamusoro.Kana paine pfupi dunhu mudunhu rekumashure IC pamusoro, zvinodikanwa kushandisa multimeter kuyera yakakodzera IC pini yedunhu uye kuitsiva neIC itsva.
2, Dambudziko remunharaunda "chiedza chakafa".
Local "dead light" zvinoreva mwenje mumwe kana akati wandei paChiratidziro che LEDizvo zvisingavheneke.Rudzi urwu rwenon light up inosiyaniswa seyenguva yakazara isina mwenje kumusoro uye chidimbu cheruvara chisina mwenje kumusoro.Kazhinji, mamiriro ezvinhu aya anokonzerwa nedambudziko nechiedza pachacho, kungave kunyorova kana kuti RGB chip iri kukuvadzwa.Nzira yedu yekugadzirisa iri nyore, iyo ndeyokuitsiva nefekitari yakapiwa LED bead spare parts.Zvishandiso zvinoshandiswa ndezviputi uye pfuti dzemhepo inopisa.Mushure mekutsiva mabhero e-LED akasara, Ongorora nekadhi rekuyedza, uye kana pasina nyaya, yakatogadziriswa.
3, Local color block inoshaya nyaya
Shamwari dzinoziva zviratidziro zve LED dzakanyatsoona rudzi urwu rwedambudziko, iro nderekuti kana iyo LED skrini ichitamba zvakajairika, pane diki diki rakaumbwa ruvara block.Dambudziko iri rinowanzo kukonzerwa nekutsva kweruvara IC kuseri kwechivharo chekudzora.Mhinduro ndeyekuitsiva neIC itsva.
4, Dambudziko rekodha remunharaunda
Dambudziko remavara emunharaunda akavharwa rakanyanya kuomarara, zvichireva chiitiko chekupenya kwemavara emavara mune dzimwe nzvimbo dze LED kuratidza skrini panguva yekutamba.Kana dambudziko iri raitika, isu tinowanzo tanga taongorora dambudziko rekubatanidza rechiratidzo chetambo.Tinogona kutarisa kana ribhoni tambo yakatsva, kana tambo yetiweki yakasununguka, zvichingodaro.Muchiito chekugadzirisa, takaona kuti aluminium magnesium wire material inobvira kupisa, ukuwo waya yakachena yemhangura ine hupenyu hurefu.Kana iyo yese yekubatanidza chiratidzo yakatariswa uye pasina matambudziko, ipapo kuchinjanisa yakashata LED module neyakajairwa yakajairika yekutamba module inogona kunyatsoona kana zvichiita kuti iyo LED module inoenderana nenzvimbo yekutamba isina kujairika yakuvadzwa.Chikonzero chekukuvara kazhinji matambudziko eIC, uye kugadzirisa uye kubata kunogona kunge kwakaoma.Hatisi kuzotsanangura mamiriro ezvinhu pano.
5, Chikamu dema dema kana nzvimbo hombe dema screen dambudziko
Kazhinji pane zvinhu zvakasiyana-siyana zvinogona kutungamirira kune ichi chiitiko.Tinofanira kuongorora uye kugadzirisa dambudziko kuburikidza nenzira dzine musoro uye matanho.Kazhinji, pane mapoinzi mana anogona kukonzera dema zvidzitiro pane imwecheteyo LED kuratidza skrini, iyo inogona kuongororwa imwe neimwe:
1, Yakasununguka dunhu
(1) Chekutanga, tarisa uye simbisa kana serial tambo inoshandiswa kubatanidza controller yakasununguka, isina kujairika, kana yakavharwa.Kana ikaita dema pakutanga kwekurodha, zvinogona kunge zvichikonzerwa nemutsara wekutaurirana wakasununguka uchikanganisa nzira yekutaurirana, zvichiita kuti skrini iite dema.Usafunga zvisiri izvo kuti chidzitiro chemuviri hachina kufamba, uye mutsara haugone kusununguka.Ndapota tarisa iwe pachako kutanga, izvo zvakakosha kuti nekukurumidza kugadzirisa dambudziko
(2) Tarisa uye simbisa kana HUB yekugovera bhodhi yakabatana neiyo LED skrini uye iyo hombe yekudzora kadhi yakanyatsobatanidzwa uye inoiswa yakatarisa pasi.
2, Simba rekupa nyaya
Ndokumbira uve nechokwadi chekuti zvese zvehardware, kusanganisira iyo control system, yakabatidzwa zvakanaka.Chiedza chemagetsi chiri kupenya here kana kuti pane kusashanda mumagetsi?Zvinokosha kucherechedza kuti kushandisa yakaderera-mhando magetsi kunowanzo tarisana nechiitiko ichi
3, Nyaya yekubatanidza ne LED unit board
(1) Mabhodhi akawanda akatevedzana haavheneke munzira yakatwasuka.Tarisa kana magetsi ekoramu iyi akajairika
(2) Mabhodhi akawanda akatevedzana haavheneke munzira yakachinjika.Tarisa kana tambo yekubatanidza pakati peyakajairika unit board uye abnormal unit board yakabatana;Kana kuti iyo chip 245 inoshanda nemazvo
4, Zvirongwa zveSoftware kana nyaya dzelambi chubhu
Kana pane muganhu wakajeka pakati pezviviri, mukana wepurogiramu kana zvigadziro zvichiita kuti zvive zvakakwirira;Kana pane yunifomu shanduko pakati pezviviri, inogona kunge iri dambudziko nechubhu remwenje.
