Waid tɛmpracha na tu nɔmba dɛn na wan datashit ɛn 4 fayl mɔd dɛn na di fil: likwid kristal faz chenj, baklayt dɛkayshɔn, polarisa yɔlɔ ɛn krak sɔlda jɔyn. Wetin de fel na ɛni ɛnd, wetin mek vaybreshɔn de kil kɔnɛkta dɛn fɔs, wetin IATF 16949 rili aks fɔ displei faktri, ɛn aw fɔ rayt wan wayd tɛmpracha spɛshal we dɛn nɔ go ebul fɔ shed.
Di frayz motoka displei kɔba tri kwik difrɛn makit dɛn. Faktɔri fit fɔ wan motoka mek-a dimand IATF 16949, PPAP ɛn rilaybiliti we dɛn kɔl ova motoka layf. Aftamaket de aks fɔ apinans ɛn mawntin dimɛnshɔn, wit wan sɛtifikeshɔn bar we smɔl fa fawe. Kɔnstrɔkshɔn ɛn agrikalchɔral mashin dɛn de aks fɔ vaybreshɔn, dɔst ɛn tɛmpracha rɛsistɛns, we di tin dɛn we EMC de op fɔ difrɛn bak frɔm pasɛnja motoka dɛn.
Miks di tri ɛn di klas mistek de apia: aftamaket prayz we dɛn aplay to faktri-fit rilaybiliti. So di fɔs tin we yu fɔ du nɔto fɔ aks if saplay kin bil ɔtomotiv TFT displei, na fɔ disayd uswan pan di tri yu bi ɛn if di motoka mek in dɔkyumentri chen de aplay. Wans dat dɔn sɛtul, prayz, lida tɛm ɛn sampul kwantiti ɔl chenj.
Kɔnkrit wan: wan faktri-fit sampul min wan kɔmplit PPAP pakej we dɛn bil pan di motoka mek in tɛmplat ɛn siks to tɛn wik; wan aftamaket sampul min tri wok yunit ɛn wan to tu wik. Semweso spɔlayt, sem panɛl, fayv tɛm difrɛns pan prɔses kɔst. If yu gi nem to di kategori we yu aks am, dat de sev bɔku kɔrɛspɔndɛns leta.
Kol nɔ jɔs de slo. Viskositi de go ɔp, di tɛm we i de ansa de go frɔm 25 milisekɔnd to pas 200, ɛn di imej de smɛl. Di kol pas dat, di likwid kristal de go insay wan smectic phase ɛn stɔp fɔ ansa ɔltogɛda, ɛn lɛf blak ɔ wayt skrin. Dis na matirial, nɔto tuning.
Bifo di likwid kristal, kol de atak tri ɔda ples dɛn. Adhesive in di FPC de tɔn brittle ɛn krak na di bɛnd. Di polariser adhesive de kɔntrakt ɛn lif na di ed dɛn. Di drayva IC nid fɔ gɛt ay vɔlɔt fɔ stat, so di kol stat na usay di fayl dɛn kin gɛda. Wan tru tru wayd tɛmpracha LCD -30C +80C kɔstɔm spɛsifikɛshɔn so de tɔk mɔ pas wan rɛnj. I de sho ɔmɔs sɛkɔn afta di pawa-ap na mayns 30, afta tu awa sok, wan kɔrɛkt pikchɔ fɔ apia. Wan rɛnj we nɔ gɛt rikavari tɛm nɔ de tɔk natin.
Ɔt na mɔ insidious bikɔs natin nɔ de fel wantɛm wantɛm. Ɛvri tɛn digri pan LED jɔnkshɔn tɛmpracha de af baklayt layf. Wan polariser we dɛn bek na 80 digri kin yɔlɔ fɔ sɔm mɔnt, i kin tɔn wayt to krim, ɛn di kɔmplen kin kam afta af ia. Liquid kristal thrεshold vכltεj de drεft wit tεmprachכ, kכntrast de fכl, εn tεmprachכ kכmpεnsεshכn de bi nεsεsary.
Di say we at pas ɔl na motoka nɔto di dashbɔd bɔt na di sɛnta kɔnsol ɔnda di winda skrin, usay di tɛmpracha we pak insay di san kin pas 90 digri, ɛn di sem eria kin go dɔŋ to 20 insay tɛn minit wans di ay kɔndishɔn dɔn rɔn. Dat thermal cycling de damej di adeziv ɛn sɔlda jɔyn dɛn pas aw di ɔt we kin de ɔltɛm kin pwɛl. Waid tempɔret tɛst so gɛt fɔ inklud tɛmal shɔk saykl wit wan stet kɔnt, nɔto jɔs stedi-stet damp ɔt.
Ɔtomotiv vaybreshɔn tɛst kin swip 10 to 500 hεtz pan sɔm g, we kin sawnd smɔl. Bɔt stil, i kin lɛf smɔl fɔ lɛ di glas ɔ di likwid kristal nɔ de wok fayn. Dɛn kin apin na di intafeys dɛn: di bond bitwin FPC ɛn glas, di kɔnɛkta bitwin FPC ɛn men bɔd, di sɔlda jɔyn dɛn na di baklayt.
Wan bond we nɔ wok de sho as sɔm vertikal layn dɛn ɔ wan dɛd zon, di mɔs kɔmɔn ripa trig pan motoka displei. Di fiks nɔto tik glas bɔt na stiffeners, wan rivays bonding prɔses, ɛn FPC routing we shep fɔ absɔb strayn. Kɔnstrɔkshɔn mashin dɛn de ad ay amplityudɔ, lɔwa frikshɔn ɛn ston impak, we de mek di haus ɛn kɔva sɛlɛkshɔn impɔtant pas di panɛl sɛf.
Wan vaybreshɔn sɔs de we dɛn nɔ kin si: fan ɛn spika dɛn. Dɛn kin sidɔm na do na di displei bɔt insay di sem os, ɛn dɛn kin mek di strɔkchɔ gladi pan wan fiks frikshɔn we kin land pan wan FPC rɛsɔnans. Dat fayl nɔ de ɛva apia na bɛnch ɛn i jɔs de sho afta sɔm tawzin kilomita. Test di divays we dɛn dɔn gɛda, nɔto di panɛl nɔmɔ.
IATF 16949 nɔto sɛtifiket, na sɔbmishɔn pakej. We dɛn aplay to displei, di kɔr na di PPAP sɛt: dizayn rɛkɔd dɛn we kɔba drɔin ɛn spɛsifikɛshɔn dɛn, prɔses flɔ dayagram, PFMEA, kɔntrol plan, mɛzhɔmɛnt sistɛm analisis, ɛn initial prɔses kapabiliti stɔdi.
Measurement system analysis ɛn kapabiliti na usay displei faktri dɛn kin stɔp. Aw dɛn de mɛzhɔ braytnɛs, kromatik ɛn kɔntrast, pan us inschrumɛnt, wit us ripitabiliti — bɔku nɔ kin ebul fɔ ansa. Kapabiliti stɔdi want statystik pan 300 kɔnsɛkutiv pis, ɛn wan smɔl program nɔ kin ebul fɔ prodyuz 300 pies. Di tɔk kin bi if istri data frɔm wan pletfɔm prodak na akseptabl ɔ if batch sampling inof, ɛn di kɔstɔma dɛn difrɛn pan dat. Sɛtul am bifo yu kot, ɔ dɛn go dɔn di sampul dɛn bifo di pepa wok dɔn.
Kapasitiv tɔch na motoka at pas na fon fɔ tri rizin dɛn. Fɔs, EMC: swich saplai, moto ɛn ignishɔn sistem de rayt strɔng wan fɔ bias di sampling. Sɛkɔn, glɔv, we di nɔt winta dɛn kin mek rutin, ɛn glɔv mɔd kin trade away sɛnsitiviti. Tɔd, wata: ren na di winda skrin, drink dɛn we dɔn rɔsh ɛn prɛshɔn was ɔl de mek wan fim na di kɔva we de mek pipul dɛn tɔch lay lay tin dɛn.
Wan TFT LCM wit kapasitiv tɔch kɔstɔm dizayn so nɔ kin stɔp if dɛn want tɔch. I gɛt fɔ gi nem to di tɔch kɔntrol, di tik we di kɔva tik ɛn di wata-rijɛkt algɔritm. We yu muv di kɔva frɔm 1.1 to 2.0 milimita, i de af di sɛnsitiviti ɛn i de fos fɔ rituning, ɛn di wata algɔritm gɛt fɔ tɛst wet pas fɔ rid ɔf wan datashit klem fɔ wata sɔpɔt.
Wan kɔtyushɔn: glɔv mɔd kin bay sɛnsitiviti wit gens, ɛn geyn kin kɔst nɔys imuniti. Na wan datashit dɛn na tu indipɛndɛnt paramita dɛn; in yus dɛn na wan tred. Aks fɔ di signal-to-nɔys rεshɔn na glɔv mɔd pas fɔ klem fɔ glɔv sɔpɔt.
Wan spɔlayt in wayd tɛmpracha prɔmis kin bi wan layn: i de ɔpreshɔn frɔm mayns 30 to plus 80.
