Cishe eminyakeni eyisikhombisa edlule, i-Sharp yaqala ukukhiqiza amaphaneli ekristalu ewuketshezi isebenzisa ubuchwepheshe bobunikazi be-IGZO. Ubuchwepheshe be-IGZO buye baba impumelelo enkulu ekukhiqizeni amaphaneli e-LCD. Ngokwesiko, i-silicon isetshenziselwe ukukhiqiza ama-transistor anjengefilimu emincane yokushayela amakristalu awuketshezi kumaphaneli, asukela “ku-amorphous” aphansi kuya ku-polycrystalline esheshayo ngokuya ngesivinini se-electron. Inkampani yaseJapane i-Sharp yaqhubekela phambili futhi yaqala ukudala ama-transistors kusukela ekuhlanganiseni kwe-oxides yezinto ezifana ne-indium, i-gallium ne-zinc. Ukuhamba kwe-electron kuma-transistors e-IGZO kukhuphuke izikhathi ezingu-20-50 uma kuqhathaniswa ne-silicon. Lokhu kuvumele ukukhuphuka komkhawulokudonsa (ukunyuswa kokuboniswa kwesibonisi) ngaphandle kokwandisa ukusetshenziswa.
Kusukela ngo-2012, ubuchwepheshe be-IGZO buye babhekana nezizukulwane ezine futhi esizukulwaneni sesihlanu. Umnikazi omusha we-Sharp, u-Hon Hai Group (Foxconn), usize ukusheshisa ukushintshela ekukhiqizeni amaphaneli e-LCD ngobuchwepheshe be-IGZO. Ukutshalwa kwezimali okuvela kumdondoshiya waseTaiwan kusize i-Sharp yethula ngonyaka odlule imigqa yokukhiqiza ama-LCD kusetshenziswa ubuchwepheshe be-IGZO. Lokhu kusho ukuthi izibonisi ze-LCD ezimangalisayo ze-Sharp zizovela ngokwandayo kuma-smartphone, ama-laptops, izibonisi zedeskithophu kanye nama-TV.
Isebenzisa isizukulwane sesihlanu sobuchwepheshe be-IGZO, i-Sharp isivele ikhiqiza eminye imikhiqizo. Ngokwesibonelo, cishe emasontweni amabili edlule thina mayelana nokukhishwa kwemonitha yokuqala ye-Sharp engu-31,5-intshi enokulungiswa kwe-8K (amaphikseli angu-7680 × 4320) kanye nezinga lokuvuselela elingu-120 Hz. Ngaphambilini kwaziwa ukuthi i-IGZO 5G yaba yisisekelo se-TV yenkampani engu-80-intshi enesinqumo esifanayo. Uma kuqhathaniswa nobuchwepheshe be-IGZO besizukulwane sesine, ukuhamba kwama-electron kukhuphuke izikhathi ezingu-4, kunciphisa ukusetshenziswa kwamaphaneli ngo-1,5% ngaphandle kokuphazamisa ukukhanya nokunikezwa kombala. Ngendlela, i-substrate eyenziwe ngama-transistors amancane-ifilimu esebenzisa ubuchwepheshe be-IGZO ifaneleka ukukhiqizwa kwamaphaneli e-OLED. Lokhu kunikeza i-Sharp ithuba lokudala amaphaneli e-OLED angaphezulu kakhulu kwemiklamo yezimbangi ngokuya ngekhwalithi nokusebenza kahle kwamandla. Asimangaze u-Sharp.
