Zvishandiso zvemotokari zvakafanana zvinokwidziridza COB yekuratidzira dashboard uye infotainment masisitimu, vachibatsirwa nekusimba kwavo uye kuoneka kwakajeka. Kunyangwe mumichina yemaindasitiri, uko maratidziro anotsungirira mamiriro ekushanda akaomarara, COB LCDs inopa yakavimbika yekuona mhinduro.
COB vs. COG: Kubatana kweKugadzira Philosophies
Kunzwisisa kwakadzama kwehunyanzvi hwekuratidzira kazhinji kunoda kudhirowa misiyano pakati pemitoo inoita seyakafanana. Muhurukuro yekubatanidzwa kwekuratidzira, mazwi maviri anowanzo simuka: COB (Chip-on-Board) uyeCOG (Chip-on-Glass). Nepo ese ari maviri achivavarira kuita diki uye kuwedzera mashandiro ekuratidzira, misimboti yavo yezvivakwa inotungamira kune akasiyana mabhenefiti uye anofarira maapplication.
Kusiyanisa kwakakosha kuri mune substrate iyo mutyairi IC akaiswa. Sekujekeswa, tekinoroji yeCOB inonamira IC yakananga paPCB, iyo inobva yapindirana neLCD. Sezvineiwo, tekinoroji yeCOG inodarika iyo yechinyakare PCB zvachose, ichikwidza mutyairi IC yakananga pane girazi substrate yeLCD panel. Uku kusungirirwa kwakananga kweIC kune girazi kunoguma mune yakatonyanya compact uye svelte module, zvichiita kuti COG ive quintessential sarudzo yemidziyo uko kuonda kwakanyanya uye huremu hushoma hwakakosha, senge ma smartphones, smartwatches, uye mamwe ekupedzisira-anotakurika emagetsi gadget.
Kubva pane dhizaini uye saizi maonero, maCOG maLCD ega ane slimmer mbiri nekuda kwekushaikwa kwePCB yakaparadzana. Uku kusanganisa kwakananga kunokwenenzvera kudzika kwemodule, kufambisira zvakanyanya kutetepa zvigadzirwa dhizaini. COB, ichiri compact inoshamisa kana ichienzaniswa nematekinoroji ekare, inochengetedza kuchinjika kunopihwa nePCB, ichibvumira mamwe akaomarara uye akagadziridzwa marongero. Izvi zvinogona kusanganisira kubatanidza zvimwe zvinhu kana kuti dhizaini yakaoma yakananga pabhodhi, izvo zvinogona kubatsira kune chaiwo maapplication anoda hungwaru hwemubhodhi kana mubatanidzwa wepamhepo.
Panyaya yekuita uye kusimba, ese matekinoroji anopa kuvimbika kwakanyanya. Nekudaro, maCOG maLCD, nekuda kwekuve neashoma mapoinzi ekubatanidza (iyo IC yakananga pagirazi), dzimwe nguva inogona kupa mupendero mukusimba kunopesana nemamwe marudzi emagetsi kushushikana. Sezvineiwo, COB LCDs, ine IC yakanyatsoiswa paPCB yakagadzikana uye yakavharidzirwa, inowanzopa chikuva chakasimba chekuita kwese kwese system, kunyanya uko kupokana nekuzunguzika kana kukanganisa ndicho chinonyanya kunetseka. Iyo yekugadziridza chimiro zvakare inosiyana; nepo maCOG modules ari kunetsa kugadzirisa nekuda kwekubatana kwakananga pagirazi, COB modules, ine IC yavo pane imwe PCB yakaparadzana, inogona kupa zviri nyore kugadzirisa uye kugadzirisa nzira.
Kufunga kwemitengo kunopawo dichotomy. Kune yakakwira-vhoriyamu kugadzirwa kwemamodule akamira, tekinoroji yeCOG inogona kuratidza kudhura-inoshanda nekuda kwemaitiro akareruka egungano uye kuderedzwa kwekushandiswa kwezvinhu mukufamba kwenguva. Nekudaro, kune maapplication anoda chaiwo magadzirirwo kana yakaderera vhoriyamu inomhanya, COB tekinoroji inowanzopa hukuru hwehupfumi, sezvo mutengo wekushandisa weiyo COG girazi molds inogona kurambidza. Hunyanzvi hwaMalio hunoenderera kusvikaLCD/LCM Segment Inoratidza yeMetering, inopa huwandu hwesarudzo dzekugadzirisa dzinosanganisira LCD mhando, ruvara rwemashure, maitiro ekuratidzira, uye tembiricha yekushandisa. Uku kuchinjika mukugadzirisa zvigadziriso zvekuratidzira kunotaura nezve kuchinjika kwematekinoroji seCOB mukusangana nezvinodiwa nebespoke, uko kugona kugadzirisa dhizaini yePCB kwakakosha.
Sarudzo pakati peCOB neCOG inozopedzisira yatsamira pane chaiyo yekumisikidza kwekushandisa. Kune madhizaini anoisa pamberi kuonda kwekupedzisira uye yakakwira-vhoriyamu yevatengi zvemagetsi, COG inowanzo tungamira. Asi, kune zvikumbiro zvinoda chiyero chekushanda kwakasimba, dhizaini inoshanduka, uye kazhinji yepamusoro yemagetsi inoenderana, COB inoramba iri sarudzo inomanikidza. Kugona kwayo kutsigira zvakanyanya kuomarara sedunhu paPCB yakabatanidzwa inoita kuti ive yakakosha kune maindasitiri, mota, uye hunyanzvi chiridzwa.
Iyo Remangwana Trajectory yeIntegrated Displays
Iko kushanduka kwe tekinoroji yekuratidzira kutsvaga kusinga peri kwekugadzirisa kukuru, kujekeswa kwakawedzerwa, uye kuderedzwa kwemafomu zvinhu. COB LCD tekinoroji, ine mabhenefiti ayo emukati, yakagadzirira kuramba iri mutambi akakosha mukufambira mberi uku. Kuenderera mberi kufambira mberi mune encapsulation zvinhu, bonding matekiniki, uye IC miniaturization ichawedzera kunatsa COB modules, kusunda miganhu yezvinogoneka mukubatanidzwa kwekuratidzira.
Iko kugona kurongedza zvinhu zvakawandisa, zvichikonzera "ultra-micro pitch" kuratidzwa, kunoburitsa zviratidziro zvine isingaenzaniswi yekuona acuity uye isina musono. Density iyi inobatsirawo kune epamusoro mutsauko ratios, sezvo kusavapo kwezvinhu zvechinyakare zvekurongedza kunoderedza kubuda kwechiedza uye kuwedzera kudzika kwevatema. Uyezve, kusimba kwemukati uye kutonga kwakanaka kwekupisa kwezvimiro zveCOB kunoita kuti vakwanise kukwikwidza maficha ekuratidzira, kusanganisira anochinjika uye kunyange pachena kuratidzwa, uko nzira dzechinyakare dzinonetsa kuzadzisa zvinodiwa nemuviri.
Malio, nekuzvipira kwayo kune yekucheka-kumucheto kuratidza mhinduro, inoramba ichiongorora kufambira mberi uku. Mhando yavo yezvigadzirwa zveCOB, kubva pakakwirira-resolution graphic modules kusvika kune yakasarudzika segment displays yezviridzwa zvakaomarara, inosimbisa hunyanzvi hwavo mukushandisa tekinoroji iyi kugona kwakazara. Ramangwana pasina kupokana richapupurira COB LCDs iri pamberi pekugadzira zvigadzirwa zvekugadzira, kufambisa inonyudza, yakasimba, uye ine simba-inogoneka yekuona mamiriro ekuona mumaindasitiri.
