Chitsauko Chechipiri: Mutyairi we LED, yechipiri inonyanya kukosha chikamu chekutungamira kuratidzwa.
Kana marambi e LED achionekwa semuviri wemunhu, saka LED inoratidzira mutyairi IC chinhu chakakosha senge yepakati tsinga system yehuropi hwemunhu, uye ndiyo inotarisira zviito zvemuviri uye kufunga kwepfungwa kwehuropi.
Kuitwa kwemutyairi IC kunotarisisa mabatiro eiyo led kuratidza skrini, kunyanya kushandiswa kwemazuva ano makuru-zvikuru uye nzvimbo dzepamusoro-soro, zvichiita kuti vanhu vawedzere kuomesesa zvinodiwa zve LED kuratidza mutyairi IC.
DriveIC evolution:
Mumakore makumi mapfumbamwe ezana ramakore rapfuura, maratidziro e LED aitongwa neruvara rumwechete uye ruviri, vachishandisa anogara ari voltage driver IC. Muna 1997, China yekutanga LED kuratidza yakatsaurirwa drive control chip 9701 yakabuda. Yakatenderedza gumi nematanhatu mimvuri yegrey kusvika 8192 mimvuri yegrey kuti uwane WYSIWYG.
Mushure meizvozvo, kune iyo LED mwenje-emitting maitiro, inogara-ikozvino dhiraivha kuti ive sarudzo inosarudzika kune yakazara-ruvara LED kuratidza mutyairi, nepo iyo yakasanganiswa 16-chanera drive inotsiva 8-chiteshi dhiraivha. Mukupera kwema1990, Toshiba wekuJapan, Allegro, naTi vekuUnited States vakatevedzana vakaunza 16-channel inogara iripo ikozvino LED driver machipisi.
Pakutanga kwezana ramakore rechi21, machipisi ekutyaira emakambani eChinese eTaiwanese akagadzirwawo akawanda uye akashandiswa. Nhasi, kuitira kugadzirisa dambudziko rePCB dhizaini yediki-pitch LED kuratidza skrini, vamwe mutyairi IC vagadziri vakaunza yakanyatsobatanidzwa 48-channel LED inogara iripo mutyairi machipisi.
Mutyairi IC maitiro ekuita zviratidzo:
Pakati pezviratidzo zvekushanda zve LED kuratidza skrini, chiyero chekuzorodza uye grey nhanho uye kutaura kwemufananidzo ndechimwe chezviratidzo zvakakosha.
Izvi zvinoda kuenderana kwakanyanya pakati peiyo LED inoratidzira mutyairi IC chiteshi, yakakwirira-kumhanya yekutaurirana interface rate, uye inogara iripo yekupindura kumhanya.
Munguva yakapfuura, iwo matatu maficha ekuzorodza mwero, greyscale, uye chiyero chekushandisa yaive mhando yehukama hwekuchinja.
Kuti tive nechokwadi chokuti chimwe kana kuti zvose zvinoratidzira zvinogona kuva zvakanyanyisa kunaka, tinofanira kupira nenzira yakakodzera zviratidzo zviviri zvasara.
Nechikonzero ichi, akawanda ma LED maratidziro akaoma kuwana akanakisa epasirese mune anoshanda maapplication, kana kuti haana kurodzwa zvakakwana.
High-speed kamera midziyo inotarisana nemitsara mitema kana yakatorwa mifananidzo, kana grey scale haina kukwana, uye kupenya kwemavara kunopesana.
Nekufambira mberi kwetekinoroji yevagadziri veIC mutyairi, kwave nekubuda muzvinhu zvitatu zvepamusoro uye matambudziko aya akagadziriswa.
Mukushandiswa kwediki-pitch LED kuratidza, kuitira kuti ive nechokwadi chekuti mushandisi anogadzika maziso kwenguva yakareba, yakaderera-mwenje uye yakakwira-grey inova yakanyanya kukosha chiyero chekuyedza mashandiro emutyairi IC.
Mutyairi IC ndeyekubatanidza dunhu rakakura kuita chip diki kushanda, kuitira kuti simba redunhu reratidziro yevhidhiyo ye LED rakagadziridzwa zviri nani, IC yakanaka kune HD LED kuratidza vhidhiyo mhando, Mavara ane hukuru hwekuona maitiro. Kuti uone yakakwira yekuzorodza frequency, yazvino yakakurumbira IC yakatevedzana inoshandiswa ndeiyi: MBI5153, ICN2163, SUM6086, nezvimwe.
Parizvino ICN2153 inokura nekukurumidza mumusika, zvakare yakagadzikana zvakanyanya asi nemutengo wakaderera uchienzaniswa neMBI5153.
MBI5153 inobva kuMacroblock, idhiraivha chip ye LED yakazara-ruvara kuratidza. S-PWM inoshandiswa kuderedza kupenya kwemufananidzo.
Iyo yekupinza mufananidzo data inoshandiswa kugadzirisa kupenya kweiyo LED vhidhiyo skrini. Kushanda tembiricha -40 kusvika +85 madhigirii Celsius.
ICN2153 inobva kuChip One. Yakashandiswa kune diki-pitch LED vhidhiyo kuratidza ine yakanakisa anti-kupindira.
Iyo yakaderera-grey yunifomu mhedzisiro haina kukanganiswa nePCB.
Inogona kugadzirisa kubuda ikozvino uye kunyatso kudzora kupenya kweHD LED kuratidza.
Chiratidziro chinogadziriswa zvinobudirira. Yakaderera-grey zvidhinha, pamwe nekukandwa kwemavara, gomba, nezvimwe zvinogona kushandiswa nechero mutsara kubvisa mameseji zvipoko.
YONWAYTECHinotungamirwa semugadziri ane hunyanzvi, isu tinogara tichikoshesa yega yega yakavimbika odha kubva kune yedu mutengi, 1920hz-3840hz yekumutsiridza mwero uye 14bit-16bit led skrini yekushandisa mukati kana kunze inogona kuve sarudzo.
