Led Display Basics
Chiratidziro che LED chiratidziro che flat panel, chinoumbwa neakawanda madiki ma LED module mapaneru, anoshandiswa kuratidza zvinyorwa, mifananidzo, vhidhiyo, masaini evhidhiyo uye mamwe akasiyana eruzivo michina.
Inonyanya kushandiswa kushambadzira kwekunze kwemukati, kuratidza, kutamba, kuita kumashure uye zvimwe zvinangwa. Inowanzo kuisirwa munzvimbo dzekutengesa, kuvaka mafacade, traffic yemugwagwa, nzvimbo dzeveruzhinji, indoor stage, makamuri emisangano, masitudiyo, horo dzemabiko, nzvimbo dzekuraira nedzimwe nzvimbo, vanoita basa mukuratidzira.
Ⅰ. iyo nheyo yekushanda yekuratidzira kwe LED
Iyo yakakosha kushanda musimboti we LED kuratidza ndeye dynamic scanning. Dynamic scanning yakakamurwa kuita line scanning necolumn scanning nzira mbiri, nzira inowanzoshandiswa ndeye line scanning. Line scanning yakakamurwa kuita 8 line scanning uye 16 line scanning.
Mune mutsara wekutarisa maitiro ekushanda, chidimbu chega chega che LED dot matrix chidimbu chine seti yekoramu drive wedunhu, column drive wedunhu inofanirwa kunge iine latch kana yekuchinja rejista, inoshandiswa kuvhara izvo zvirimo kuti zvionekwe mune yezwi mode data. Mune mutsara wekutarisa maitiro ekushanda, mutsara wakafanana we LED dot-matrix chidimbu chezita rimwechete mutsara wekutonga pini zvakabatanidzwa mukufanana pamutsara, mitsara ye8, uye pakupedzisira yakabatanidzwa kune mutsara wekufambisa mutsara; mutsara dhiraivha wedunhu unofanirwa kuve nelatch kana shift rejista, inoshandiswa kuvhara mutsara wekutarisa chiratidzo.
LED inoratidzira mbiru dhiraivha yedunhu uye mutsara dhiraivha wedunhu inowanzo shandiswa microcontroller control, inowanzoshandiswa microcontroller ndeye MCS51 yakatevedzana. LED kuratidza zvemukati zvinowanzo kuchengetwa muchimiro chezwi modhi mune microcontroller yekunze data memory, izwi modhi i8-bit binary nhamba.
Ⅱ. ruzivo rwekutanga rwekuratidzwa kweLed
1, chii chinonzi LED?
LED ichidimbu-emitting diode diode chipfupiso (LIGHT EMITTING DIODE), neyakajeka-emitting diode gadziriro inoumbwa nedhizaini yekuratidzira. Indasitiri yekuratidzira yakataura kuti iyo LED inoreva iyo LED inogona kuburitsa inooneka wavelengths.
2, chii chinonzi LED kuratidza?
Kuburikidza nedzimwe nzira dzekudzora, iyo LED mudziyo dhizaini inoumbwa yekuratidzira skrini.
3, chii chinonzi LED kuratidza module?
Kune masekete uye yekumisikidza chimiro chekuona, ine mabasa ekuratidzira, anogona kuwanikwa kuburikidza neyakapfava gungano kuratidza basa reiyo yekutanga unit.
4, Chii chinonzi LED kuratidza module?
Inoumbwa nenhamba yemapikisi ekuratidzira, akazvimiririra akazvimiririra, anogona kuumba diki diki yekuratidzira kwe LED. Muenzaniso 8 * 8, 8 * 7, nezvimwewo.
5. Chii chinonzi pixel pitch (dot pitch)?
Chinhambwe chepakati pakati pemapikisi maviri akatarisana, iyo diki kukwirira, ipfupi nhambwe yekuona. Indasitiri inowanzopfupikiswa P kuratidza nzvimbo yepakati.
6, Chii chinonzi pixel density?
Iyo inozivikanwawo se dot density, kazhinji inoreva huwandu hwepixels paskweya mita pachiratidziro.
7, Chii chinonzi kupenya kwakajeka?
LED inoratidzira unit nzvimbo yakapihwa nechiedza chakasimba, iyo unit iCD / sikweya mita, inongoiswa ndeye sikweya mita kuratidza yakapihwa nekusimba kwechiedza;
8, chii chiri kupenya kweiyo LED kuratidza?
Kupenya kwe LED kunoreva kushanda kwakajairwa kwechiratidziro, iyo yekuratidzira unit nzvimbo yeinopenya kusimba, iyo unit ndeye cd / m2 (kureva, mangani maCD ekupenya kwakanyanya pamativi emamita enzvimbo yechiratidziro.
11, grey level chii?
Iyo grey nhanho yekuratidzira kwe LED chiratidzo chinoratidza chiyero chemufananidzo wechiratidziro. Iyo grey nhanho yevhidhiyo skrini inowanzokamurwa kuita 64 mazinga, 128 mazinga, 256 mazinga, 512 mazinga, 1024 mazinga, 2048 mazinga, 4096 mazinga zvichingodaro. Iyo yakakwirira ye grayscale level, kujeka kwechiyero chemufananidzo, iyo general grayscale level ye256 kana kupfuura, musiyano wemufananidzo hauna kunyanya kukura.
12, chii chinonzi mbiri-ruvara, pseudo-ruvara, yakazara-ruvara kuratidza?
Kuburikidza neakasiyana mavara emwenje-emitting diode anogona kuumbwa neakasiyana maratidziro, maviri-ruvara anoumbwa neruvara dzvuku, girinhi kana yero-girinhi mavara maviri, pseudo-ruvara inoumbwa netsvuku, yero-girinhi, yebhuruu mavara matatu akasiyana, akazara. -ruvara runoumbwa neruvara rutsvuku, rwakachena girini, bhuruu yakachena matatu mavara akasiyana.
13, chii chinonzi moire?
Iri mubasa rekupfura rekuzara-ruvara rwe LED kuratidzwa, LED inoratidzira skrini pachava nemamwe mvura asina kujairika emvura, aya madhiri emvura mufizikisi anonzi "moiré".
14, chii chinonzi SMT, chii chinonzi SMD?
SMT is surface mounted tekinoroji (SURFACE MOUNTED tekinoroji kwenguva pfupi), parizvino ndiyo inonyanya kufarirwa tekinoroji uye maitiro muindasitiri yegungano remagetsi; SMD chinhu chakamisikidzwa pamusoro (pamusoro chakaiswa mudziyo kwenguva pfupi).
Chiratidziro che LED imhando nyowani yeruzivo rwekuratidzira midhiya, iko kutonga kwechiedza-emitting diode kuratidza modhi ye flat panel display screen, inogona kushandiswa kuratidza zvinyorwa, mifananidzo uye mamwe marudzi e static information ne animation, vhidhiyo nemamwe marudzi ruzivo rune simba, LED yemagetsi kuratidza seti microelectronics tekinoroji, tekinoroji yekombuta, kugadzirisa ruzivo mune imwe, ine mavara akajeka, yakakura dynamic range, kupenya kwepamusoro, hupenyu hurefu, yakagadzikana uye yakavimbika, etc. Advantages, inoshandiswa zvakanyanya mune zvekutengesa media, tsika yekuita musika, nzvimbo dzemitambo, kuparadzira ruzivo, kuburitswa kwenhau, kutengeserana kwezvivimbiso, nezvimwe, zvinogona kusangana nezvinodiwa zvenzvimbo dzakasiyana. Zvinoenderana neiyo color base color inogona kukamurwa kuita imwe chete yemavara kuratidza uye yakazara ruvara kuratidza.
