Wan kɔlɔ tɔchskrin kin mek tɛmostayt tan lɛk fon, bɔt tri tin dɛn we dɛn nid kin win am: tɛn ia pan wan bateri, tɛn ia we yu nɔ gɛt blank skrin, ɛn tɛn ia we yu nɔ gɛt prayz inkris. Di kɔst strɔkchɔ fɔ wan sɛgmɛnt displei, aw fɔ fiks di sɛgmɛnt layout, ustɛm wan monokrom grafik panɛl fit am, ɛn wetin de insay di spɛsifikɛshɔn.
Wan kɔlɔ tɔchskrin tɛmostayt de win ɛvri tred sho. We i dɔn de na di wɔl, di tin dɛn we di pɔsin we de yuz am nid nɔ tan lɛk fon in yon. I gɛt fɔ displei ɔltɛm, bikɔs di tɛmpracha fɔ rid we nɔbɔdi nɔ de tɔch am. I gɛt fɔ pul ɔlmost ɛni pawa, bikɔs bɔku Yuropian ɛn Nɔt Amɛrika mɔdel dɛn de rɔn pan batri ɔ tif sɔm tɛn miliamp frɔm di 24V HVAC saplai. Ɛn i gɛt fɔ las tɛn ia, bikɔs fɔ chenj tɛmostayt min fɔ pul di wɔl plet, we ɔdinari pipul dɛn we de yuz am nɔ go du.
Dɛn tri tin dɛn de we dɛn nid na di say we di kɔlɔ panɛl dɛn wik. Wan kala TFT baklayt we dɛn lɛf pan de drɔ ɔndrɛd miliwat ɛn i nɔ go sev wan winta pan sɛl dɛn. Polariser ɛn baklayt degrad visibly ɔnda kɔntinyu ɔpreshɔn. Ɛn yunit kɔst de rɔn tri to fayv tɛm wan sɛgmɛnt displei. So, wan kɔstɔm sɛgmɛnt LCD fɔ smat tɛmostayt nɔto bak-wɔd chuk; na di optimum כnda wan spεsifi k sεt כf kכnstrakshכn.
Wan sɛgmɛnt displei kot split to tri layn dɛn: di glas mask, we na wan tɛm kɔst; di sampul chaj; ɛn di prodakshɔn yunit prays. Mask kɔst skel wit sɛgmɛnt kɔmplisiti ɛn glas saiz ɛn tipikli land insay di tawzin to lɔw tɛn tawzin renminbi, we di yunit prays kin bi sɔm renminbi. Tu bad tin dɛn kin apin afta dat. Dכn fכ tawzin yunit dεm insay wan ia di mask nכ kin abzכp εn wan sεgmεnt displei de stכp fכ bi chip. Ɛn fɔ chenj di sɛgmɛnt layout min fɔ pe fɔ di mask bak.
So negoshieshɔn nɔ fɔ chase di yunit prays bɔt i fɔ sɛtul aw i go bi fɔ ridizayn insay tri ia. If di rodmap dɔn ɔlrɛdi tink bɔt ɛkstra aykɔn ɔ nyu ridin, layt ɔl di pat dɛn naw ɛn lɛf spay wan dɛn we yu nɔ yuz; dat smɔl pas fɔ opin di mask bak tu ia afta dat. Na dat mek bak wan kɔmpiten kɔstɔm displei mɔdyul spɔlayt kin kɔntinyu fɔ aks wetin ɔda tin di prɔdak go nid fɔ sho.
Layout luk lɛk drɔ, bɔt na tred bitwin viewing angle, segment count ɛn di hausing window. twist nematic de gi wan sכmכl kכn, roughly tati digri vεtikal; supertwisted nematic de widen am pan di kɔst fɔ kɔntrast. Mɔ sɛgmɛnt min mɔ drayva layn dɛn, ɛn di COM to SEG ratio de kap ɔmɔs dijit dɛn fit. We dɛn dɔn kɔt di winda fɔ di os, di say we dɛn de si nɔ go ebul fɔ chenj.
Tɛmostat dɛn kin kɛr wan spɛshal tin we dɛn nid: bɔku tɛm wan big nɔmba kin impɔtant, so di men dijit dɛn kin de na di bɛst say fɔ si we di mɔd, fan ɛn bateri aykɔn dɛn kin sidɔm nia di ed. Dɔn lɛf di pat dɛn we yu nɔ yuz, nɔto fɔ sho bɔt fɔ mek yu rivishɔn tumara bambay nɔ nid nyu mask. Dat layn nɔ de ɛva apia na wan spɛsifikɛshɔn ɛn na di singl mɔs kɔst-sɛvin pies fɔ ɛkspiriɛns insay sɛgmɛnt prɔjek dɛn.
Di siling fɔ wan sɛgmɛnt displei na dat i kin jɔs sho di tin dɛn we dɛn dɔn drɔ bifo tɛm. Di mɔnt we wan prɔdak nid arbitri tɛks fɔ wan mɔlti-langwej mɛnyu, arbitri kɔv fɔ ɛnaji istri, ɔ arbitri aykɔn dɛn, sɛgmɛnt dɛn kin dɔn ɛn wan wan kɔlɔ grafik LCD kɔstɔm saiz kin bi di ansa.
Tri tɛst dɛn de disayd am: sɔpɔt fɔ bɔku langwej dɛn, we na mandatory fɔ ɛkspɔt mɔdel dɛn; istri data displei; ɛn di ebul fɔ ad skrin dɛn tru di famwɔya ɔpdet dɛn. Ɛni wan pan di tri de jɔstify wan dɔt-matris panɛl; wit nכn pan dεm, dכt matris de כnli rayz kכst εn lεng divεlכpmεnt. I ayd kɔst na di font laybri, we de yuz MCU flash, so kɔnt wetin lɛf fɔ aplikeshɔn lɔjik bifo yu pik di kɔntrol.
Wan tɛmostayt de stak di frɔnt kɔva, displei, men bɔd ɛn riya kɔva, ɛn di dip we di wɔl-plet de stɔp di tɔtal. Wan COG LCD modul de bon di drayva IC dairekt to di glas, we de pul wan sɛpret paket ɛn di bod eria we i nid, we de sev wan to tu milimita agens wan COB dizayn. Na tɛmostayt na da milimita de bɔku tɛm na di difrɛns bitwin fɔ fit ɛn nɔ fit.
Kɔnɛkshɔn na di sɛkɔn bɛnifit. COG de link to di bod tru wan FPC ɔ elastomer kɔnɛkta, we de pul pin ɛn sɔkɛtɛ frɔm asɛmbli, wan prɔses stɛp ɛn wan fayl pɔynt. Rilaybiliti na di tɔd wan: nɔ sɔlda jɔyn pan IC lid min se i nɔ go pwɛl ɔnda drɔp ɛn vaybreshɔn. Di prayz na riparaybiliti, bikɔs wan bond COG nɔ kin ebul fɔ gɛt in kɔntrol riples, na di wan ol modul nɔmɔ. Fɔ tɛmostayt, usay fɔ ripɛnt min fɔ chenj di yunit ɛni we, da prayz de na sɔntin we pɔsin kin gri wit.
Aplayans dɛn nɔ de muv wit kɔshɔma ilɛktronik spid. Wan tɛmostayt pletfɔm kin liv tri to fayv ia, bɔku tɛm dɛn kin chenj di kɔlɔ ɛn trim pas fɔ mek dɛn mek am bak wit mashin. So displei ɔda dɛn kin tan lɛk wan big lanch ɔda we dɛn kin fala wit ia dɛn we dɛn kin put smɔl smɔl tin dɛn bak, nɔto fɔ bay fresh ɛvri kwata.
We yu de sos frɔm wan LCD modul OEM faktri na Chaina, sɛtul tu tin: udat gɛt di mask we di program dɔn, ɛn aw lɔng dɛn kip am. Mask we di faktri gɛt ɛn we dɛn kip fɔ tu ia min se dɛn fɔ ful-ɔp am bak afta dat, dɛn nid fɔ opin am bak; wan mask we yu gɛt, ɔ we dɛn ol fɔ fayv ia bay agrimɛnt, de mek pɔsin ebul fɔ tɔk bɔt aw fɔ ful-ɔp. Minimum ɔda kwantiti pan sɛgmɛnt glas kin fala di ikɔmik kɔt fɔ di shit, sɔm ɔndrɛd to sɔm tawzin pis, so negoshiet arawnd ɔmɔs pis wan prodakshɔn rɔn de yield pas yu ɛni ia dimand, ɔ di yunit prays nɔ de ɛva muv.
Wan spɛsifikɛshɔn we wan saplay kin akt pan rɔn to nayn layn dɛn: ɔtlayn ɛn viu eria, glas tik, sɛgmɛnt drɔ wit sɛgmɛnt difinishɔn tebul, drayv skim wit COM ɛn SEG kɔnt ɛn bias, ɔpreshɔn vɔlɔt, ɔpreshɔn ɛn stɔrɔj tɛmpracha, baklayt kɔlɔ, braytnɛs ɛn if i de pan, kɔnɛkshɔn we wit pin difinishɔn, ɛn ɛni ia volyum wit layf tɛm we dɛn de ɛkspɛkt.
