Nekukura nekukurumidza kwetekinoroji yepasi rose yeFlat Panel Display (FPD), mhando dzakawanda dzezviratidziro dzakabuda, dzakadai seLiquid Crystal Display (LCD), Plasma Display Panel (PDP), Vacuum Fluorescent Display (VFD), nezvimwewo. Pakati pazvo, zviratidziro zveLCD zvinoshandiswa zvakanyanya mukugadzirisa mafambiro ekuona nekuda kwezvakanaka zvadzo zvekupenya kwakanyanya, maangle makuru ekuona, mavara akapfuma, uye kushandiswa kwesimba shoma.

Chidzitiro cheLCD rudzi rwechinhu chinogadzirwa nemhedzisiro yekutenderera kwe liquid crystal molecules. Nheyo huru ndeyekushandisa optical rotation effect yechinhu chakati (liquid crystal substance) uye nheyo yekuti liquid crystal molecules dzichachinja marongerwo adzo mumunda wemagetsi kudzora simba re polarized light richipfuura nepakati pe liquid crystal, kuitira kuti chinangwa chekuratidzwa chibudirire. TFT-LCD (thin film transistor liquid crystal display) ndeimwe ye liquid crystal displays inonyanya kushandiswa, ichishandisa thin film transistor technology kuvandudza kunaka kwemufananidzo.

Nekuti chinhu chegirazi remvura chiri muLCD screen hachibudisi chiedza pachacho, panodiwa chimwe chitubu chechiedza, saka kune machubhu emwenje sematuru emwenje kumativi ese echidzitiro chekuratidza, uye huwandu hwemachubhu emwenje hunoenderana nekupenya kwechidzitiro cheLCD. Chiratidziro chegirazi remvura chepakutanga chaive nemachubhu maviri emwenje epamusoro neapasi, uye gare gare chakagadzira chimiro chemwenje mina nemwenje mitanhatu. Pane panel yemwenje yekumashure (kana panel yemwenje yakaenzana) uye firimu rekuratidzira kumashure kwechidzitiro chegirazi remvura. Panel yemwenje yekumashure inoumbwa nezvinhu zve fluorescent uye inogona kuburitsa chiedza nebasa guru rekupa sosi yemwenje yekumashure yakafanana. Kune zviratidziro zvegirazi remvura, kupenya kunowanzoenderana nesosi yemwenje yekumashure. Kana sosi yemwenje yekumashure yakajeka, kupenya kweLCD yese kuchawedzerawo zvinoenderana.

Kupenya kuri pamberi pechidzitiro kunoreva kupenya kwesimba pachikamu chimwe nechimwe (chinhu chakavhenekerwa), uye chiyero chayo chekuyera i nits (NIT), kureva, candela/square meter (inonziwo cd/m²). Masikirini emazuva ano eLCD anoshandisa mafirimu ekuwedzera kupenya kwechiedza, achiwedzera huwandu hwemwenje, uye anowedzera simba remwenje kuti awedzere kupenya kwechiratidziro zvakanyanya, zvichiita kuti ive yakakodzera mamiriro akasiyana-siyana ekushandisa.

Parizvino, kupenya kwemaLCD akawanda ari pamusika kuri pakati pe300-500cd/m2.²MaTouchDisplay anogona kugadzirisa madhigirii akasiyana ekupenya kwepamusoro zvichienderana nemamiriro ekushanda kwemuchina, kusvika ku2000cd/m². Zvichinyatsoonekwa nechiedza chakasimba chekunze, mhinduro dzakagadzirwa dzinogona kugutsa zvinodiwa nevatengi vakawanda. Pamusoro pezvo, kuti zvizadzise zvinodiwa nemashandisirwo akasiyana-siyana emaindasitiri, TouchDisplays inopawo sarudzo dzakawanda dzekugadzirisa skrini dzakadai sedzisingapindi mvura muchina wese, dzinodzivirira kupenya, dzinodzivirira kupisa kwakanyanya, uye dzinodzivirira kuputika kwegirazi.

MuChina, kune nyika

Semugadziri ane ruzivo rwakakura muindasitiri, TouchDisplays inogadzira mhinduro dzakangwara dzekubata.
