Mamiriro ekuvandudzwa kweTFT LCD

Zviratidziro zvemavara zveTFT (Thin-Film Transistor), sechikamu chikuru chetekinoroji yemazuva ano yekuratidzira, zvakachinja-chinja tekinoroji nekukurumidza uye zvakawedzera musika kubva pakutengeserana kwazvo muma1990. Zvinoramba zviri mhinduro huru yekuratidzira mumagetsi evatengi, michina yeindasitiri, nedzimwe nzvimbo. Ongororo inotevera yakarongwa muzvikamu zvitatu: nhoroondo yekuvandudza, mamiriro etekinoroji aripo iye zvino, uye tarisiro yeramangwana.

I. Nhoroondo yeKugadzirwa kweTFT-LCD
Pfungwa yetekinoroji yeTFT yakatanga kuoneka muma1960, asi makambani ekuJapan haana kusvika kuma1990 apo akakwanisa kugadzira zvinhu zvakawanda zvekutengesa, kunyanya zvemalaptop nemaLCD monitors ekutanga. MaTFT-LCD echizvarwa chekutanga aiganhurirwa ne resolution yakaderera, mutengo wakakwira, uye goho rakaderera rekugadzira, asi zvishoma nezvishoma akatsiva CRT displays nekuda kwezvakanaka zvakaita se slim form factor uye kushandiswa kwesimba shoma. Kubva muna 2010 zvichienda mberi, maTFT-LCD akapinda mumisika yakaita semafoni, madhisiki emotokari, zvishandiso zvekurapa, uye masisitimu ekudzora maindasitiri, ukuwo achitarisanawo nekumanikidzwa kwemakwikwi kubva kuOLED. Kuburikidza nekuvandudzwa kwetekinoroji senge Mini-LED backlighting, mashandiro akavandudzwa mune mamwe mashandisirwo, kusanganisira mamonitor emhando yepamusoro.

II. Mamiriro eTekinoroji eTFT-LCD Pari Zvino
TFT-LCD indasitiri yakakura zvikuru, nemitengo yekugadzira yakaderera zvakanyanya pane yeOLED, kunyanya mumapurogiramu makuru akadai seTV nemamonita, uko inotonga musika. Kumanikidzwa kwemakwikwi uye hunyanzvi zvinonyanya kukonzerwa nekukanganiswa kweOLED. Kunyange zvazvo OLED ichiita zvakanaka mukuchinja-chinja uye contrast ratio (nekuda kwehunhu hwayo hwekuzviburitsa pachayo ine contrast isingaperi), TFT-LCD yakaderedza musiyano nekushandisa Mini-LED backlighting ine local dimming kuti ivandudze mashandiro eHDR. Kubatanidzwa kwetekinoroji kwakawedzerwawo kuburikidza nequantum dots (QD-LCD) yemhando dzakasiyana dzemavara uye kuiswa kwetekinoroji yekubata, zvichiwedzera kukosha.

III. Tarisiro Yeramangwana yeTFT-LCD
Kuvhenekesa kweMini-LED, nezviuru zvema micro-LED ayo ekudzima magetsi munzvimbo, kunoita kuti pave nemazinga akasiyana-siyana akafanana neeOLED ukuwo zvichichengetedza kugara kwenguva refu uye mabhenefiti emutengo weLCD. Izvi zvinoiisa senzira yakakosha mumusika wezviratidziro zvepamusoro. Kunyangwe TFT-LCD inochinjika isingachinjiki zvakanyanya pane OLED, kugona kwayo kukotama kwakawanikwa uchishandisa magirazi akatetepa kana mapurasitiki, zvichibvumira kutsvaga mashandisirwo akadai semota nemidziyo inopfekwa. Mamiriro ekushandisa anoramba achikura mune mamwe mativi—semuenzaniso, maitiro ekuona mascreen akawanda mumotokari itsva dzesimba anosimbisa chinzvimbo chikuru cheTFT-LCD, nekuda kwekuvimbika kwayo uye kushanda kwayo zvakanaka. Kukura mumisika yekune dzimwe nyika, senge India neSoutheast Asia, uko kudiwa kwemagetsi evatengi kuri kuwedzera, kunotsigirawo kuvimba neTFT-LCD mumidziyo iri pakati nepakati kusvika pasi.

OLED ndiyo inonyanya kushandisa mafoni emhando yepamusoro uye ma "display markets" anochinjika uye inoshanda pamwe chete neMicro LED, iyo inotarisa ma "screens" makuru (semuenzaniso, ma "commercial video walls"). Panguva iyi, TFT-LCD inoramba ichipinda mumisika mikuru nepakati nekuda kwehuwandu hwe "cost-performance ratio". Mushure memakumi emakore ekugadzirwa, TFT-LCD yasvika pakukura, asi inoramba ichishanda kwenguva refu kuburikidza nehunyanzvi hwetekinoroji senge Mini-LED neIGZO, pamwe nekushandisa misika midiki yakaita seyemotokari nemaindasitiri. Chinhu chikuru chayo ndechekuti: mutengo wekugadzira mapaneru makuru wakaderera zvakanyanya pane weOLED.

Tichitarisa mberi, TFT-LCD ichanyanya kutarisana nemakwikwi akasiyana pane kutarisana neOLED zvakananga. Nerutsigiro rwematekinoroji akaita seMini-LED backlighting, zvinotarisirwa kuumba mikana mitsva mumusika wepamusoro-soro. Kunyangwe kusiyanisa tekinoroji yekuratidzira kuri tsika isingadzoreki, TFT-LCD, inotsigirwa ne ecosystem yakakura uye hunyanzvi hunoramba huripo, icharamba iri tekinoroji yekutanga muindasitiri yekuratidzira.
