IT House June 17th sangano rekutsvagisa nhau Omdia nguva pfupi yadarika yakaburitsa chirevo chekuti muna 2020 Samsung ichagadzira yakaderera-tembiricha polysilicon uye oxide (LTPO) yakaonda-firimu transistor (TFT) inoshanduka OLED inoratidzira yeiyo Galaxy Note 20 yakatevedzana, uye inogona zvakare kuve Apple inotevera. gore.Iphone inopa.Nhau dzekutanga dzakati iPhone 13 ichashandisa LTPO OLED skrini.
Samsung Display yakagadzira yayo LTPO TFT kuitira kuvandudza mashandisiro emagetsi, uyenguva pfupi yadarika yakatumidza tekinoroji yayo yeLTPO seyakasanganiswa oxide uye polysilicon (HOP) TFT.
Samsung Electronics yakatanga 1.2 uye 1.4-inch inoshanduka OLED Galaxy Watch Active 2 ine LTPO TFT muna 2019, uye yakaratidza kuti LTPO TFT inopfekwa bhatiri hupenyu huri nani pane LTPS.Muna 2020, Samsung Electronics ichashandisa LTPO tekinoroji kugadzira inochinjika OLED kuratidza kune yayo nyowani Galaxy Note 20 akatevedzana, zvinoreva kuti Samsung's LTPO tekinoroji ichashandiswa mu6.x-inch smartphones.
Apple yakashandisawo tekinoroji yeLTPO TFT kugadzira maOLED anochinjika eApple Watch Series 4 muna 2018, ayo akavandudza hupenyu hwebhatiri zvakanyanya.Munguva pfupi yapfuura, Apple inoronga kushandisa tekinoroji yeLTPO TFT kugadzira maOLED anochinjika ePhones ayo muna 2021 aine Samsung Display, LG Display, JDI, BOE nevamwe vagadziri vekuratidzira.LTPO TFT inogona kuve yakakosha tekinoroji yekugadzira OLED.
LTPO inogona kuchengetedza zvakanyanya kushandiswa kwesimba
LTPO TFT musanganiswa weoxide TFT uye polysilicon TFT.Iyo ine zvakanakira maviri TFT matekinoroji.LTPS ndiyo yakanakisa TFT tekinoroji yekushandisa maOLED maratidziro ane yakakwira erekitironi kufamba, asi zvakare ine yepamusoro-soro yekubuda kwenzvimbo.Oxide ndiyo yakanakisa TFT tekinoroji yekushandisa maOLED maratidziro ane yakaderera off-state leakage ikozvino, asi mafambiro ayo erekitironi akadzikira.
Iyo yakanyanya kuvuza ikozvino yeLTPS TFE inoderedza kupenya kwemufananidzo nenguva, saka furemu yega yega inoda kunyora voltage yekutyaira.Kune rimwe divi, iyo yakaderera leakage ikozvino yeLTPO inongoda kunyora voltage yekutyaira mune yekutanga furemu kana skrini isiri kufamba.Naizvozvo, LTPO TFT inogona kushandiswa seLTPS kuratidza nharembozha inoda kukurumidza kushandura mamiriro epixel wedunhu, semamuvhi nemitambo.Inogona zvakare kushandiswa seye oxide yedunhu kuratidza static zvirimo semifananidzo kana wachi.Mamiriro emhando iyi yekuratidzira pixel circuit inoshanduka zvishoma nezvishoma.
LTPO TFT ichave yakakosha tekinoroji yekugadzira OLED
Mazhinji nharembozha mabhureki anotarisa pakuvandudza hupenyu hwebhatiri yechishandiso, nekuti ivo vanofanirwa kuramba vachiwedzera saizi uye basa rechiratidziro, senge 5G kutaurirana, akawanda makamera uye ma sensors ekuchengetedza.Naizvozvo, kuitira kuti usangane nezvinodiwa zvemhando dzemafoni emhando, mashandisirwo emagetsi ari kuramba achiwedzera kukosha kune vagadziri vekuratidzira.
Muchirevo, LTPO TFT inogona kuchengetedza 5-15% yekushandiswa kwesimba rekushandisa zvichienzaniswa neLTPS TFT.Nekudaro, kugadzirwa kweLTPO TFT kunoda kuwedzera mari yekushandisa uye mutengo wakakwira kupfuura weLTPS TFT.Naizvozvo, vagadziri vepaneru vanonetsekana nezve nzira yekudzikisa yekuwedzera mari yekushandisa pasina dambudziko rekuwandisa.
