Isikrini sokuthinta esinezintambo ezine
Isikrini sokuthinta esinezintambo ezine siqukethe izendlalelo ezimbili eziphikisayo.Olunye ungqimba lunebhasi eliqondile emaphethelweni angakwesokunxele nangakwesokudla esikrinini, kanti esinye isendlalelo sinebhasi elivundlile ngaphansi nangaphezulu kwesikrini, njengoba kukhonjisiwe kuMfanekiso 1.
Umfanekiso 1 Isihlukanisi se-voltage sitholwa ngokuxhumanisa ama-resistors amabili ochungechungeni [6]
Linganisa ohlangothini lwe-X-eksisi, chema ibhasi elingakwesokunxele liye ku-0V, kanye nebhasi elingakwesokudla eliya ku-VREF.Xhuma ibhasi elingaphezulu noma eliphansi ku-ADC, futhi ukulinganisa kungenziwa lapho izingqimba ezingaphezulu neziphansi zixhumene.
Umfanekiso 2 Izendlalelo ezimbili eziphikisayo zesikrini sokuthinta esinezintambo ezine
Ukuze kulinganiswe isiqondiso se-Y-eksisi, ibhasi eliphezulu licheme ne-VREF futhi ibhasi eliphansi licheme ku-0V.Xhuma itheminali yokufaka ye-ADC ebhasini elingakwesokunxele noma ebhasini elingakwesokudla, futhi i-voltage ingalinganiswa lapho ungqimba olungaphezulu luxhumene nongqimba olungezansi.Umfanekiso 2 ubonisa imodeli eyenziwe lula yesikrini sokuthinta esinezintambo ezine lapho izendlalelo ezimbili zixhumene.Esikrinini sokuthinta esinezintambo ezine, indlela ekahle yokuxhuma iwukuxhuma ibhasi echemile ku-VREF kutheminali yokufaka eyireferensi ephozithivu ye-ADC, kanye nokuxhuma ibhasi elimiswe ku-0V kutheminali yokufaka eyireferensi engalungile ye-ADC.
I-voltage divider ibonakala ngokuxhuma ama-resistors amabili ochungechungeni
Izendlalelo ezimbili eziphikisayo zesikrini sokuthinta esinezintambo ezine
Isikrini sokuthinta esinezintambo ezinhlanu
Isikrini sokuthinta esinezintambo ezinhlanu sisebenzisa isendlalelo esiphikisayo kanye nesendlalelo esibambayo.Isendlalelo se-conductive sinokuthintana, ngokuvamile emaphethelweni aso ohlangothini olulodwa.Kukhona othintwayo ekhoneni ngalinye kwamane ongqimba oluphikisayo.Ukuze ulinganise endaweni ye-X-axis, susa amakhona angaphezulu kwesokunxele naphansi kwesokunxele uye ku-VREF, futhi amakhona aphezulu kwesokudla naphansi kwesokudla asekelwe.Njengoba amakhona angakwesokunxele nangakwesokudla ane-voltage efanayo, umphumela ufana nebhasi elixhuma izinhlangothi kwesokunxele nesokudla, kufana nendlela esetshenziswe esikrinini sokuthinta ezinezintambo ezine.Ukuze ulinganise nge-eksisi ye-Y, ikhona elingaphezulu kwesokunxele kanye nekhona eliphezulu kwesokudla kutholwe ku-VREF, bese kuthi ekhoneni elingezansi kwesokunxele kanye nekhona elingezansi kwesokudla kutholwe ku-0V.Njengoba amakhona angaphezulu naphansi aku-voltage efanayo, umphumela ucishe ufane nebhasi elixhuma imiphetho ephezulu nangaphansi, efana nendlela esetshenziswe esikrinini sokuthinta esinezintambo ezine.Inzuzo yale algorithm yokulinganisa ukuthi igcina i-voltage ekhoneni eliphezulu kwesokunxele nangezansi kwesokudla ingashintshiwe;kodwa uma kusetshenziswa izixhumanisi zegridi, ama-eksisi X kanye no-Y adinga ukuhlehliswa.Esikrinini sokuthinta esinezintambo ezinhlanu, indlela engcono kakhulu yokuxhuma iwukuxhuma indawo engaphezulu kwesokunxele (icheme njenge-VREF) kutheminali yokufaka eyireferensi ephozithivu ye-ADC, bese uxhuma ikhona elingezansi kwesokunxele (licheme ku-0V) kokokufaka okuyireferensi okungekuhle. I-terminal ye-ADC.
I-Glass substrate iyingxenye ebalulekile yokukhiqizwa kwe-TFT-LCD, futhi izindleko zayo zibalelwa ku-15% kuya ku-18% wesamba sezindleko ze-TFT-LCD.Ithuthukiswe kusukela kulayini wesizukulwane sokuqala (300mm × 400mm) kuya kulayini wamanje wesizukulwane seshumi (2,850mm × 3,050).mm), idlule esikhathini esifushane nje seminyaka engamashumi amabili.Kodwa-ke, ngenxa yezidingo eziphakeme kakhulu zokwakheka kwamakhemikhali, ukusebenza kanye nezimo zenqubo yokukhiqiza ye-TFT-LCD yengilazi engaphansi, ubuchwepheshe bokukhiqiza ingilazi ye-TFT-LCD yomhlaba wonke kanye nemakethe sekuyisikhathi eside isetshenziswa ngabakwaCorning e-United States, i-Asahi Glass kanye I-Electric Glass, njll. Igunyazwe izinkampani ezimbalwa.Ngaphansi kokugqugquzelwa okuqinile kokuthuthukiswa kwemakethe, izwe elikhulu lezwe lami nalo laqala ukubamba iqhaza ngenkuthalo ku-R&D nasekukhiqizweni kwama-glass substrates e-TFT-LCD ngo-2007. Njengamanje, inani lemigqa yokukhiqiza ingilazi ye-TFT-LCD yesizukulwane sesihlanu futhi ngenhla zakhiwe eShayina.Kuhlelelwe ukwethula amaphrojekthi amabili esizukulwane sesizukulwane esiphezulu se-crystal crystal substrate engxenyeni yesibili ka-2011. Lokhu kunikeza isiqinisekiso esibalulekile sokwenziwa kwasendaweni kwezinto zokusetshenziswa ezikhuphuka nomfula kubakhiqizi be-TFT-LCD ezweni lami kanye nenani elibalulekile. ukunciphisa izindleko zokukhiqiza.
Isikrini sokuthinta esinezintambo eziyisikhombisa
Indlela yokuqaliswa kwesikrini sokuthinta esinezintambo eziyisikhombisa iyafana nesikrini sokuthinta esinezintambo ezinhlanu ngaphandle kokuthi umugqa owodwa wengezwe ekhoneni elingenhla kwesokunxele nasekhoneni elingezansi kwesokudla.Lapho wenza ukulinganisa kwesikrini, xhuma ucingo olulodwa ekhoneni eliphezulu kwesokunxele ku-VREF, bese olunye ucingo kutheminali eyireferensi ephozithivu ye-SAR ADC.Ngesikhathi esifanayo, intambo eyodwa ekhoneni elingezansi kwesokudla ixhunywe ku-0V, kanti enye ixhunywe kutheminali eyireferensi eyinegethivu ye-SAR ADC.Isendlalelo se-conductive sisasetshenziswa ukukala i-voltage yesihlukanisi se-voltage.
Isikrini sokuthinta esinezintambo eziyisishiyagalombili
Ngaphandle kokwengeza ucingo olulodwa ebhasini ngalinye, indlela yokusebenzisa isikrini sokuthinta esinezintambo eziyisishiyagalombili iyafana naleyo yesikrini sokuthinta esinezintambo ezine.Ebhasini le-VREF, intambo eyodwa isetshenziswa ukuxhuma ku-VREF, kanti enye intambo isetshenziswa njengesithenjwa esihle sesiguquli sedijithali-kuya-analogi se-SAR ADC.Ebhasini elingu-0V, intambo eyodwa isetshenziswa ukuxhuma ku-0V, kanti enye intambo isetshenziswa njengesethenjwa esinegethivu okokufaka kwesiguquli se-digital-to-analog se-SAR ADC.Noma iyiphi izintambo ezine kungqimba olungachemile ingasetshenziswa ukukala i-voltage yesihlukanisi sikagesi.
