Chii chinonzi COB LED Display Chokwadi?

Nekuda kwekutsvaga kwevanhu kweyekupedzisira-yepamusoro tsananguro led kuratidza, iyo pixel pitch yezviratidziro zve LED inogara ichiderera.

Sechizvarwa chekutanga chetekinoroji yekuratidzira, iyo yechinyakare SMD kuratidzwa yave yakakura kwazvomushure memakore anopfuura gumidevelopment.

Saka, ndeipi nzira yehunyanzvi inozopedzisira ichishuvira munguva yeiyo micro led kuratidza?

Nekuvandudzwa kwe LED kuratidza tekinoroji, nzira dzehunyanzvi dzakadai seCOB (Iyo ipfupi yeChip Pabhodhi) inobuda.

Zvakare, nzira dzakasiyana dzekurongedza dzinogona kufananidzwa neakasiyana chip zvimiro.

SMD, inozivikanwa seyepamusoro mounted zvishandiso, inoreva kushandisa pamusoro pegomo tekinoroji kurongedza zvigadzirwa zve LED.

Iyo inogona kuvharira kapu yemwenje, bracket, crystal element, uye zvimwe zvinhu mune akasiyana zvirevo zvemarambi.

Paunenge uchigadzira iyo yekuratidzira unit ine nzvimbo dzakasiyana dzemini LED kuratidza skrini, bhedhi remwenje rinosungirirwa kune redunhu bhodhi nemuchina wekumhanya weSMT une high-temperature reflow welding. 

Tichifunga nezve kuoma kwehunyanzvi panguva yekuvhara, vagadziri vanofarira SMD kuburitsa diki-nzvimbo yedhijitari yedhijitari yekuratidzira skrini.

SMD ndiyo yekutanga tekinoroji yemicro LED kuratidza skrini ine pixel spacing isingasviki 10mm pamusika.

Kune rimwe divi, COB, ipfupi yeChip On Board, inyowani yekurongedza tekinoroji inovhara machipisi e LED, kwete marambi e LED, yakananga paPCB.

Nokudaro, COB-LED ichasunungurwa kubva pakukura kwemuviri weSMD nokuda kwekugadzirisa kwepamusoro seP0.9375.

Digitalmicro led display screens muP0.9375mm, P1.25mm, P1.5625 mm uye P1.875 inowanikwa neCOB.

Uyezve, hazvirambike kuti COB ine zvirinani zvemuviri zvimiro.

Iwo ma module akafukidzwa neCOB haasi akareruka chete pane ayo ane SMD asiwo ane maonero akakura.

Kuenzaniswa neSMD, izvo COB inotungamira kuratidza inogona kuunza bhenefiti kwauri sepazasi:

1;Excellent heat dissipation

Chimwe chezvinangwa zveiyi tekinoroji kugadzirisa dambudziko rekupisa kupisa kweSMD neDIP.

Chimiro chakareruka chinochipa zvakanakira pamusoro pemamwe marudzi maviri ekupisa kwemwaranzi.

2;Inokodzera yakamanikana pixel pitch LED Display

Sezvo machipisi akabatana zvakananga nePCB board, nhambwe dziri pakati peimwe unit dzakatetepa kuti dzideredze pixel pitch kuti ipe vatengi mifananidzo yakajeka.

3;Rerutsa kurongedza

Sezvatataura pamusoro, chimiro cheCOB LED chiri nyore kupfuura SMD neGOB, saka maitiro ekurongedza ari nyore, zvakare.

4;Yepamusoro isingapindi mvura

Iine innovative chip pabhodhi ye glued module, inogona kunyatso chengetedza iyo LED pane LED module kubva mumvura kana humidity.

5;Zvirinani Anti-kudhumhana

Yakakosha modular dhizaini ine anti-kudhumhana gluing inokwanisa kuve nekuvhunduka proof basa, ichipa ekupedzisira-yepamusoro dziviriro ye LED mune akasiyana maitiro.

6;Kupfuura Dust-proof.

Nekuvharisa kwepamusoro kuita kwezvinhu zvitsva, iyo COB LED skrini pani kubva kuYONWAYTECH LED haina guruva zvachose nekujeka kwakanakisa uye inopa yakanakisa yekuona maitiro ane yakakwirira yekuzorodza mwero uye yakafanana ruvara.

Chikonzero chekuvimbika kwepamusoro ndechekuti tekinoroji yeCOB inogona kubvisa chinongedzo chekutonga mune imwe nzira yekugadzira mwenje.

Uye zvakare, inobvisawo bhedhi remwenje pamusoro peiyo reflow welding process, kuitira kuti tembiricha yepamusoro munzira yechinyakare irege kukanganisa iyo LED chip uye welding mutsara.

Yakanakisa kupisa kupisa uye oxidation kuramba kunopawo kuvimbika kwakanyanya.

Zvakare, COB inotora yakakwira yakajairwa tekinoroji kudzivirira kutadza kwekuratidzira kwe LED kunokonzerwa nemvura, hunyoro, UV, uye kumwe kukuvadza.

Inotsigira kushanda kwemamiriro ekunze ese uye inogona kushanda mukupisa kwakanyanya mu -30 kusvika +80 madhigirii.

Iyo yakazara yekudzivirira maitiro inodzivirira kubonderana kana kukwenya.

Iyo mini LED inoratidzira skrini inogona kucheneswa nejira rakanyorova kana rakasvibiswa.

Neruzivo rwuri pamusoro, unogona kuona kuti COB tekinoroji yakakwirira pane SMD tekinoroji muLED kuratidza skrini. 

Uye kana iwe uchitsvagaMicro LED inoratidza, unogona kureva zvimwe zvigadzirwa zve YONWAYTECH LED DISPLAY.

Bata neYONWAYTECH LED DISPLAY timu kuti uwane rumwe ruzivo ndapota.
