Hoʻolauna ʻana i nā hōʻike OLED

Hōʻike nā hōʻikeʻike OLED (Organic Light-Emitting Diode) i kahi ʻenehana hōʻike kipi, me ko lākou pono nui e waiho ana i ko lākou waiwai hoʻopuka ponoʻī, e hiki ai ke hoʻokele kukui pololei i ka pae pixel me ka ʻole o ka pono no kahi module backlight. Hāʻawi kēia ʻano hoʻonohonoho i nā pono kupaianaha e like me nā lakio ʻokoʻa kiʻekiʻe loa, nā kihi nānā kokoke i 180-degere, a me nā manawa pane microsecond-level, ʻoiai ko lākou ʻano lahilahi a maʻalahi hoʻi e kūpono iā lākou no nā polokalamu pale pelu. ʻO kahi hōʻikeʻike OLED maʻamau he waihona multi-layer e komo pū ana me nā substrates, nā papa electrode, a me nā papa hana organik, me ka papa hoʻopuka organik e hoʻokō ana i ka electroluminescence ma o ka hui hou ʻana o ka electron-hole. ʻO ke koho ʻana o nā mea organik like ʻole e ʻae ai i nā kala hoʻopuka kukui hiki ke hoʻololi ʻia.

Mai kahi hiʻohiʻona hana, hoʻokomo nā hōʻike OLED i nā lua a me nā electrons ma o ka anode a me ka cathode, kēlā me kēia, me kēia mau mea lawe ukana e hui hou ana i loko o ka papa hoʻokuʻu organik e hana i nā excitons a hoʻokuʻu i nā photons. ʻAʻole wale kēia ʻano hana hoʻomālamalama pololei e hoʻomaʻalahi i ka hoʻonohonoho hōʻike akā hoʻokō pū i ka hana kala maʻemaʻe. I kēia manawa, ua ulu ka ʻenehana i ʻelua mau ʻōnaehana mea nui: nā OLED molekole liʻiliʻi a me nā OLED polymer, me nā ʻano hana doping pololei e hoʻonui hou ana i ka pono luminous a me ka maʻemaʻe o ke kala.

Ma ka pae noi, ua komo ka ʻenehana hōʻike OLED i nā ʻano like ʻole e like me nā mea uila mea kūʻai aku, nā kaʻa, a me nā mea lapaʻau. ʻO nā kelepona akamai kiʻekiʻe a me nā TV e noho aliʻi ana ma ka mākeke ma muli o ko lākou kiʻi kiʻekiʻe, ʻoiai nā hōʻike kaʻa e hoʻohana i ko lākou maʻalahi e hiki ai i nā hoʻolālā dashboard curved. Loaʻa ka pōmaikaʻi o nā mea lapaʻau mai ko lākou mau ʻano ʻokoʻa kiʻekiʻe. Me ka puka ʻana mai o nā ʻano hou e like me nā OLED aniani a me nā OLED hiki ke hoʻolōʻihi ʻia, ke hoʻonui wikiwiki nei ka ʻenehana hōʻike OLED i nā ʻano e kū mai ana e like me nā ʻōnaehana home akamai a me ka ʻoiaʻiʻo hoʻonui ʻia, e hōʻike ana i ka hiki ke hoʻomohala nui ʻia.
