Hōʻikeʻike ʻia ʻo LCD ke kikowaena nui a me ka wehewehe huahana

ʻO ka pale hōʻike LCD ka mea hōʻike maʻamau i ko mākou ola a me kā mākou hana. Hiki ke loaʻa iā ia ma nā lolouila, televise, nā polokalamu kelepona, a me nā huahana uila ʻē aʻe. ʻAʻole hāʻawi wale ka module crystal crystal i nā hopena hiʻohiʻona kiʻekiʻe, akā hāʻawi pū kekahi i ka ʻike ma o kāna kikowaena nui. E kālele ana kēia ʻatikala i ke kikowaena nui a me ka wehewehe ʻana o ka huahana o Tft Display.
 
Hoʻokomo ʻia ke kikowaena nui o Tft Display ma o nā ʻenehana kikowaena like ʻole. ʻO kekahi o nā ʻenehana kikowaena maʻamau ka RGB, LVDS, EDP, MIPI, MCU, a me SPI. He mea nui kēia mau ʻenehana kikowaena i ka hoʻolālā a me ka hana o nā pale LCD.
 
ʻO ka pānaehana RGB ʻo ia kekahi o nā mea maʻamau maʻamau o ka pale hōʻike LCD. Hana ia i nā kiʻi mai nā pika o ʻekolu kala: ʻulaʻula (R), ʻōmaʻomaʻo (G), a me ka uliuli (B). Hōʻike ʻia kēlā me kēia pika e kahi hui like ʻole o kēia mau kala kumu ʻekolu, e hopena i kahi hōʻike kala kiʻekiʻe. Loaʻa nā pānaʻi RGB ma nā mea nānā kamepiula kahiko a me nā pale kīwī.
 
ʻO ka LVDS (Low Voltage Differential Signaling) kahi ʻenehana hoʻohana maʻamau i hoʻohana ʻia no nā modula aniani wai kiʻekiʻe. He haʻahaʻa haʻahaʻa haʻahaʻa-voltage hōʻailona ʻenehana kikowaena. Ua hoʻomohala ʻia kahi ʻano hoʻoili hōʻailona wikiō kikohoʻe e lanakila ai i nā hemahema o ka hoʻohana ʻana i ka mana kiʻekiʻe a me ke kiʻekiʻe EMI electromagnetic interference i ka wā e hoʻouna ana i ka ʻikepili kiʻekiʻe kiʻekiʻe kiʻekiʻe ma ka pae TTL. Hoʻohana ka LVDS output interface i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (e pili ana i 350mV) e hoʻouna ʻokoʻa i ka ʻikepili ma nā ʻāpana PCB ʻelua a i ʻole nā ​​kaula kaulike, ʻo ia hoʻi, ka hoʻouna ʻana i nā hōʻailona ʻokoʻa haʻahaʻa haʻahaʻa. ʻO ka hoʻohana ʻana i ka LVDS output interface e hiki ai i nā hōʻailona ke hoʻouna ʻia ma nā laina PCB ʻokoʻa a i ʻole nā ​​kaula kaulike ma ka helu o nā haneli Mbit/s. Ma muli o ka hoʻohana ʻana i nā ala haʻahaʻa haʻahaʻa haʻahaʻa a me nā ala hoʻokele haʻahaʻa o kēia manawa, loaʻa ka leo haʻahaʻa a me ka hoʻohana haʻahaʻa haʻahaʻa. Hoʻohana nui ʻia ia e hoʻonui i ka wikiwiki o ka lawe ʻana i ka ʻikepili o ka pale a hōʻemi i ka interference electromagnetic. Ma ka hoʻohana ʻana i ka interface LVDS, hiki i nā pale LCD ke hoʻouna i ka nui o nā ʻikepili i ka manawa like a loaʻa i ke kiʻi kiʻi kiʻekiʻe.

ʻO ka interface EDP (Embedded DisplayPort) he hanauna hou o ka ʻenehana kikowaena Tft Display no nā kamepiula a me nā papa. Loaʻa iā ia nā pōmaikaʻi o ka bandwidth kiʻekiʻe a me ka helu hoʻoili data kiʻekiʻe, hiki ke kākoʻo i ka hoʻonā kiʻekiʻe, kiʻekiʻe refresh rate a me ka hana kala ʻoi aku ka maikaʻi. Hoʻohana nui ʻia ia e hoʻonui i ka wikiwiki o ka lawe ʻana i ka ʻikepili o ka pale a hōʻemi i ka interference electromagnetic. Ma ka hoʻohana ʻana i ka interface LVDS, hiki i nā pale LCD ke hoʻouna i ka nui o nā ʻikepili i ka manawa like a loaʻa i ke kiʻi kiʻi kiʻekiʻe. Hiki i ka pānaehana EDP ke loaʻa i ka pale hōʻike LCD i nā hopena ʻike maikaʻi aʻe ma nā polokalamu kelepona.

 

ʻO MIPI (Mobile Industry Processor Interface) kahi maʻamau maʻamau no nā polokalamu kelepona. Hiki i ka MIPI ke hoʻouna i ka wikiō kiʻekiʻe a me ka ʻikepili kiʻi me ka hoʻohana haʻahaʻa haʻahaʻa a me ka bandwidth kiʻekiʻe. Hoʻohana nui ia i nā pale LCD o nā polokalamu kelepona e like me nā smartphones a me nā papa.

 

Hoʻohana nui ʻia ka MCU (Microcontroller Unit) no kekahi mau mana haʻahaʻa, haʻahaʻa haʻahaʻa Tft Hōʻike. Hoʻohana maʻamau ia i nā mea uila maʻalahi e like me nā calculators a me nā wati akamai. Hiki i ka MCU ke hoʻomalu pono i ka hōʻike a me nā hana o ka pale hōʻike LCD me ka haʻahaʻa haʻahaʻa. ʻO ka hoʻoili ʻana i ka ʻikepili me 8-bit, 9-bit, 16-bit a me 18-bit. Hoʻokaʻawale ʻia nā pilina i: CS/, RS (koho inoa), RD/, WR/, a laila ka laina ʻikepili. ʻO nā mea maikaʻi: ka mana maʻalahi a maʻalahi, ʻaʻohe uaki a me nā hōʻailona synchronization e pono ai. ʻO ka hemahema: hoʻopau ia i ka GRAM, no laila paʻakikī ke hoʻokō i kahi pale nui (QVGA a i luna paha).

 

ʻO SPI (Serial Peripheral Interface) kahi ʻenehana maʻalahi a maʻamau i hoʻohana ʻia no ka hoʻopili ʻana i kekahi mau kamepiula liʻiliʻi, e like me nā wati akamai a me nā mea lawe lima. Hāʻawi ka SPI interface i nā wikiwiki wikiwiki a me ka nui o ka pūʻolo liʻiliʻi i ka wā e hoʻouna ai i ka ʻikepili. ʻOiai ʻoi aku ka haʻahaʻa o kona ʻano hōʻike, kūpono ia no kekahi mau mea pono ʻole nā ​​koi kiʻekiʻe no nā hopena hōʻike. Hāʻawi ia i ka MCU a me nā ʻaoʻao peripheral like ʻole e kamaʻilio ma ke ʻano serial e hoʻololi i ka ʻike. ʻEkolu mau papa inoa ʻo SPI: hoʻopaʻa inoa SPCR, papa inoa kūlana SPSR a me SPDR papa inoa. Loaʻa nā mea hana peripheral i ka mea hoʻoponopono pūnaewele, Tft Display driver, FLASHRAM, A/D converter a me MCU, etc.

 

I ka hōʻuluʻulu ʻana, ʻo ke kikowaena nui o ka pale hōʻike LCD e uhi i nā ʻenehana kikowaena like ʻole RGB, LVDS, EDP, MIPI, MCU a me SPI. Loaʻa i nā ʻenehana kikowaena like ʻole nā ​​noi like ʻole i nā hōʻike Tft like ʻole. ʻO ka hoʻomaopopo ʻana i nā hiʻohiʻona a me nā hana o ka ʻenehana ʻenehana pale LCD e kōkua iā mākou e koho i nā huahana module kristal wai e kūpono i kā mākou pono, a hoʻohana maikaʻi a hoʻomaopopo i ke kumu hana o nā pale LCD.
