LCD min be ni ɲɛɛ kelen ye, o b’a yira ni fɛɛn dɔ be yera. TFT b’a filɛ n’a be se ka baara kɛ n’a ye. O danfara be ye fili hakɛ la, baarakɛla be jaaw kalan joona cogo min na ani bi tile fɛɛn be cogo min na.
LCD min be ni ɲɛɛ kelen ye, o b’a yira ni fɛɛn dɔ be ye; TFT dɔ b’a ɲɛnabɔ n’a be se ka baara kɛ n’a ye. Active matrix gives each pixel its own drive, which moves contrast, response and colour count up by an order of magnitude, and makes icons, charts, full Chinese layout and touch all possible. Adamaden ni masin ka ɲɔgɔndan be bɔ pankuru dɔ la min be sɛbɛri yɔrɔ fila yira ka taga finɛtiri dɔ la min be se ka ɲɔgɔndan dɔ baara.
O danfara be ben o fɛɛn lo kan. Users stop memorising dense codes, error rates fall, field staff read graphs faster than numbers, and the product looks more modern because it can draw. Ka wari dɔɔni bɔ minɛnw na, o be yɛlɛmaniba dɔ san lɔnniya hakɛ la — o lo kama ɲɛgɛnw be jigira ka bɔ fɛɛn ɲumanw na ka don fɛɛnbaw la.
TFT ka interface sugandili be komi gearbox dɔɔni: sugandili ɲuman tɛ yen, min be bɛn n’a ye dɔrɔn. MCU ka yɔrɔ be baara kɛ ni pinɛ damadɔw ye ani a boli ka nɔgɔ, a be bɛn MCU fitininw ma ani baarakɛcogo telimanw ma, k’a sɔrɔ i yɛrɛ ka ɲi ka buffer dɔ mara. Parallel RGB be yɛlɛma joona ani a be bɛn videwow ni animasiyɔnw ma, nka a be baara kɛ ni pinɛ caaman ye ani a ka dɔgɔ boli wagatijanw na. SPI ye min ka dɔgɔ ni bɛɛ ye — layidu damanin be pankuru kulɛri fitinin dɔ minɛ — ni yɛlɛmani dannin ye. LVDS ni MIPI be sɔn mɔgɔw ka ɲɔgɔn sɔsɔli ma ani ka boli janw kɛ, u be bɛn yɔrɔbaw la ani kuran ka mankan be kɛ yɔrɔ minw na.
Interface sugandili be daminɛ i ka jatigi be se ka min di, i ka routing yɔrɔ hakɛ min b’i kɔnɔ ani i ka ɲi ka kɔnɔnakow hakɛ min lakuraya. O saba sigi ani interface fanba sigi. An ka fɛɛrɛw b’a to interface, voltage ani pin ɲɛfɔli be se ka yɛlɛma ka kɛɲɛ ni dilan cogo ye, o la, i ka sisitɛmu t’a ɲini ka katalogu yɔrɔ dɔ ladon.
Nafa b’a la ka span bonyaba dɔ sɔrɔ. N’i ka minanw be bolola minanw ni panneau minw be se ka baara kɛ ɲɔgɔn fɛ, ani yiracogo modɛliw be bɔ feerekɛla kelen lo fɛ, o tuma na, bolifɛnw ka kode, lajɛnba kɛcogo ani feerekɛlaw ka ɲɛminɛcogo bɛɛ be ɲɔgɔn fɛ ani ɛnzeniyɛriw ka lɔnniya be se ka baara kɛ n’u ye tugun. A ka c’a la, mɔgɔw ka ɲɔgɔn sɔrɔli kɔrɔ ye bolifɛn fila, sɛgɛsɛgɛri kɛcogo fila ani baara kɛcogo fila ye.
0,69-inch kulɛri fitininw be baara kɛ ni minan fitininw ani fani dontaw ye; 2.4, 3.5, 4.3, 5.0 ani 7.0 santimɛtiriw be bololafɛnw ni pankuruw ka baarakɛcogobaw datugu; 10.1 inch be baara kɛ ni yɔrɔw ye minw be se ka ɲɔgɔn sɔrɔ ani kunnafoni tablo. A mako be yɔrɔ minw na, u be se ka maga a la ani u be se ka cover-lens ni backlight kulɛri yɛlɛma. O bonya layidu be minanw fanba yiracogo makoɲɛfɛnw dafa k’a sɔrɔ u ma yɛlɛma don u ka feerekɛlaw la.
Tuma caaman na, mɔgɔw b’a miiri ko fani kulɛriw ye fɛɛnw sugu ye minw be kɛ ka kɛɲɛ ni sariyaw ye, nka yɔrɔ min be se ka kɛ ka mɔgɔw sago kɛ, o ka bon i n’a fɔ fani kulɛri kelenw. Bonya be se ka kɛ min tɛ sariya ye, ɲɛda ni pin ɲɛfɔli be tugu dilan cogo kɔ, FPC janya ani kabɔli bɔyɔrɔ be tugu lajɛn kɔ, kɔfɛyeelen ka yeelen n’a kulɛri be tugu lamini kɔ, funteni hakɛ be tugu yɔrɔ kɔ ani filɛli sira be tugu sigiyɔrɔ kɔ. Fɛɛrɛ min be maga mɔgɔ la (resistif wala capacitif) ani cover-lens baara kɛcogo fana be se ka ɲɛfɔ.
O la, a be se ka kɛ ko an ka resolution, interface cogoyaw, lajɛnba hakɛ, baarakɛyɔrɔ ani magali min ka ɲi ka kɛ, ani baara min be bɛn n’o ye, o be kɛ feerekɛla fɛ. 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. Kulɛri pankuruw be se ka yiriwa ka kɛ desɛn ye fana, u tɛ bɔ gafe dɔ kɔnɔ dɔrɔn — o be wagati caaman bɔ poroze fitininw na.
O la, a be se ka kɛ ko mɔgɔw be mɔgɔw hakili sama kosɔbɛ, nka min be TFT poroze dɔ bali, o ye kaare buffer ye. RGB565 yiracogo min be 240 ni 320 la, o mako be kilobayiti 150 ɲɔgɔn na foto kelen kelen bɛɛ la. Ni RAM ka dɔgɔ ni mikrokontrolɛri min be jatigi fɛ, o dilancogo be jigi ka taga kulɛri fitinin dɔ la, a be pankurun boli ka tɛmɛ seriyali dɔ fɛ min mako tɛ yɔrɔ ka kadre buffer la, wala a be kɛnɛma hakilijigifɛn dɔ fara a kan ani kɔntrolɛri dɔ min be yɛlɛmaniw mara. Ka o latigɛ kafokulu labɛnnin kɔ, o man di; k’a latigɛ sugandili wagati la, o ye telefɔni weele ye.
Refresh rate be baara kɛ n’a ye fana. Paralɛli walima RGB yɔrɔ be kadriw ɲɔndi joona nka a be MCU ka bandwidth caaman dumu; SPI be i n’a fɔ wariko fɔɔ i ka yɛlɛmani wagati jati ka kɛɲɛ ni laɲinita hakɛ ye ani k’a ye ko wagati ma to baarakɛla fɛ ka koo wɛrɛ kɛ. An be yɔrɔ hakɛ jati ka kɛɲɛ ni jatigi ka RAM n’a ka lɛrɛ ye, ani an be fotow hakɛ min be se ka sɔrɔ, o fɔ poropozisiyɔn kɔnɔ sanni k’a to mɔgɔw k’o lɔn mɔgɔw ladontuma na.
Ekipu caaman be MCU sugandi fɔlɔ ani ekran filanan, ani n’u be yɛlɛmani don u ka koow la, o be se ka sugandiliw dɔgɔya o yɔrɔnin bɛɛ. RGB ani LVDS/MIPI ɲɔgɔndanw b’a ɲini jatigi fɛ a ka yiracogo yɛlɛmalan dɔ ta min be bɛn n’o ye; SPI ye duniɲa kuru bɛɛ ta ye nka a ka ca a la. MCU labɛnnin kɔ dɔrɔn, a b’a yira ko laɲinita lakurayali hakɛ tɛ se ka sabati, wala ko pin hakɛ ka surun, ani dilancogo be kɔsegi.
O mankan labɛnnin lo ka yiracogo laɲiniw labɛn ka bɔ fɛɛnw laɲiniw la — kaare hakɛ, resolution, kulɛri dunni, n’a mako be magali la — ani ka interface ni MCU bɔ o la. Fɛɛn minw kɔnɔkow ye ikoniw ni sɛbɛriw ye, SPI wala MCU ka yɔrɔ min be modɛli dɔ kan ani min be ni basiki sɛgɛsɛgɛrikɛla ye, o be bɔ; kuruw, videwow ka ɲɛyiraliw ani tablo minw be yɛlɛmayɛlɛma, olu be RGB wala bandwidthba lo ɲini.
An be interface ani frame rate sɛgɛsɛgɛ ɲɔgɔn fɛ ni client ka yiracogo kɔnɔkow ani MCU ka platformu ye, ani ka frame rate sumaninw di. Ka sɛgɛsɛgɛri kɛ a be se ka boli teliya min na tiɲɛn na sanni i ka layidu ta, o be MCU sugandili yɛlɛmani kelen bali.
Ka yɔrɔ dɔ fara TFT LCM kan min be se ka maga mɔgɔ la, o be koo saba yɛlɛma ka tɛmɛ panneau kan. A fɔlɔ ye kuran ka yɔrɔ ye: yiracogo be se ka kɛ RGB, SPI walima MIPI ye hali bi, nka touch controller be segi ka na I2C walima SPI kan i n’a fɔ minɛn filanan, o la, jatigi mako be bisi filanan na ani yɔrɔ filanan min be tigɛ. A filanan ye stɛki ye: datugulan, magafɛn, yiracogo ani yelifɛn dɔ, ani u ni ɲɔgɔn cɛ yɔrɔ kelen kelen bɛɛ ye yɔrɔ ye, bugun wala yɔrɔ dɔ be se ka bɔ yɔrɔ min na. A sabanan ye porogramu fitinin ye — touch controller mako b’a yɛrɛ ka konfiguration la ani, n’a be baara kɛ ni glove wala wet-finger ye, a yɛrɛ ka tuning lo.
Danfara min be feerekɛlaw ni ɲɔgɔn cɛ, o b’a yira fana o yɔrɔ la. TFT LCD modɛli dilanbaga dɔ be Sinuwa jamana na min be se ka la a la tiɲɛn na, ale bena touch controller ka I2C ladɛrɛsi ci, a ka cover glass ja, a ka bonding specification ani a ka misaliya min kisira funteni yɛlɛmani ma, k’a sɔrɔ a ma ɲininga siɲɛ fila.
