O yɛlɛmani be kɛ yɔrɔ naani na: a ka vitɛsi, a ka boon lɔcogo, a ka kuran dilancogo n’a ka porogramu fitininw ani a ka baarakɛcogo. Ekipu fanba be miiri fɔlɔ dɔrɔn lo la.
Kɔnɔnafɛnw yɛlɛmani be kɛ vitɛsi kan. I ka ɲi ka min yira, i be se k’o masiki tigɛ kɛrɛnkɛrɛnnin na ka kɛɲɛ ni kɔnɔnakow ye, resolution tɛ dan katalogu nimɔrɔw ma, segment pattern be tugu i ka sɛbɛri kɔ ani mode positif wala négatif be bɔ yeelen min na i be baara kɛra min kɔnɔ. TN, STN, FSTN ani VA cogoyaw be danfara ni filɛli kɛcogo sifa caaman di, k’a sɔrɔ polarizatɛri minw be yɛlɛma wala minw be yɛlɛma pewu, olu lo b’a latigɛ n’o ekran be se ka kalan tile yeelen kɔnɔ.
O layiri kɔlɔlɔ tigitigi ye ko i be min yira, i be min sɔrɔ. Ekipu caaman be interface dɔ dilan fɔlɔ ani u be ekran dɔ ɲini, ani u be saratiw tigɛ n’u m’o sɔrɔ. Ka mɔgɔw lasun u ka koow kɛ, o be yɛlɛmani don u ka koow la ani ka hɔɔrɔnya segi u ma interface la. O kɔfɛko fana ye tiɲɛn ye: n’a kɔnɔkow ka nɔgɔ, i man kan ka paramɛtiriw sara i mako tɛ minw na.
O boon lɔcogo be ni koo caaman ye ka tɛmɛ mɔgɔw jigi be min kan. Wajibi tɛ a bonya ka kɛ santimɛtiri hakɛ dafanin ye; yɔrɔ min be filɛ ani modɛli labɛncogo be se ka tugu lajɛnba yɔrɔ kɔ. PCB bonya n’a cogoya be se ka kɛ yɔrɔ o yɔrɔ ye, ni tigɛyɔrɔw ani yɔrɔw ye minw be tugu i ka boon kɔ, ani nɔrɔcogo be se ka kɛ pin header, FPC, terminal block wala juru nɛgɛ ye min be kɛ ka kɛɲɛ ni mɔgɔ sago ye. Cover-lens kulɛri ani kɔfɛla yeelen kulɛri be se ka ɲɛfɔ fana.
O fɛɛnw bɛɛ be nɔɔ to lajɛnba kan. Flex janya ye hakɛ min ye, a be bɔ fan min na, a be yɛlɛma yɔrɔ min na — o lo b’a yira ka gwɛ ni minan bannin be ɲɔgɔn lajɛnna ka ɲɛ. Lajɛnba lɔnniya be komi fɛɛn fitinin dɔ, nka ni tile kɔnɔ, sekɔndi bisaba min be fara a kan, o ye dilanyɔrɔ musaka ye. Ka ɲɔgɔndan cogoya ani juru bɔyɔrɔ labɛn siɲɛ kelen sugandili wagati la, o be wari caaman kisi ka tɛmɛ n’i y’a yɛlɛma yɛlɛmani kɔ.
O yɛlɛmani tɛ dan minanw dɔrɔn ma. Ɲɔgɔnkunbɛnw be se ka kɛ paralɛli ye, SPI, I2C wala UART, ni lozisiyɛli tansɔn ye ka bɔ 2,5V la ka taga se 5,5V ma. O boon be se ka MCU, RTC, flash, funteni lɔnbaga, kɔfɛyeelen bolibaga ani nivo yɛlɛmalanw don a la. Min nafa ka bon ka tɛmɛ o bɛɛ kan, o ye ko porogramu fitinin be se ka display driver, font library ani command parsing ta ka kɔn — jatigi be cikan kelen ci ani ekran b’a lɔn a ka ɲi ka min yira.
Tuma caaman na, mɔgɔw t’o layiri nafa jati dɔɔni. Ni sɛbɛri porogaramu ni rendering logic tɛ jatigi kan, jatigi ka baara be dɔgɔya kosɔbɛ; MCU fitininw kan minw ka jatebɔ fanga man bon, ka yiracogo baara yɛlɛma ka taga modɛli fan fɛ, o be surunya ka latigɛli kɛ. An ka yɛlɛmani be o ɲɔgɔndanw datugu ɲɔgɔn fɛ ni pin ɲɛfɔli ye, sanni k’u siri o kɔ.
O yɔrɔ laban ye baarakɛyɔrɔ ye. Funteni hakɛ saba: 0C ka taga se +50C ma, izini ka funteni hakɛ -20C ka taga se +70C ma, -40C ka taga se +85C ma. Filɛri sira be sugandi ka bɔ lɛrɛ 6, 12, 3 ani 9 la ka kɛɲɛ ni yɔrɔ yɛrɛ yɛrɛ ye min be yɛlɛma; a ka jugu ani yiracogo be bɔ yɔrɔ dɔw la.
Ka yɔrɔ naani bɛɛ fɔ ka gwɛ yɔrɔnin kelen, o lo b’a to mɔgɔw be se ka yɛlɛmani don u ka sago la: fɛɛn minw ka kan ka yira (sɛbɛri, jaaw wala kulɛri, yɔrɔ hakɛ min be se ka kɛ), boon bonya ani lajɛnyɔrɔ min be se ka kɛ, ekran be filɛ yɔrɔ min na n’a donna ka ban, ani fanga min be sɔrɔ ani a be yɔrɔ min na. Ni olu lo, baara min be kɛ ka bɛn ɲɔgɔn ma, o be taga joona joona. An be fura ni sɛrɛkili dɔ segi lɛrɛ mugan ni naani kɔnɔ; paramɛtiriw ye katalogu sɔngɔw ye ani mɔgɔw ka yɛlɛmani be tugu i ka dilan cogo kɔ — ka yɛlɛmani don fɔɔ a ka ɲi, o lo ye kumaden ka miiriya bɛɛ ye.
