ʻO ke ʻano ʻokoʻa ma waena o ka OLED a me ka LCD

I nā makahiki i hala iho nei, me ka holomua wikiwiki o ka ʻenehana hōʻike, ua kū mai ka hōʻike OLED ma ke ʻano he mea nui i ka hanauna hou o nā ʻenehana hōʻike, e huki ana i ka nānā nui mai nā kula a me nā ʻoihana. ʻO ka ʻenehana hōʻike OLED, i ʻike ʻia hoʻi he ʻenehana diode light-emitting organik, he ʻano pale kū hoʻokahi a he nui nā pono ma mua o ka ʻenehana LCD (liquid crystal display) kuʻuna. Ke hoʻohana nui ʻia nei ia ma ka ʻāpana uila mea kūʻai.

Hiki ke hoʻohālikelike maopopo ʻia ke ʻano o kahi pale OLED me kahi "hamburger hoʻomālamalama." Ua like kēlā me kēia ʻāpana OLED me kahi ʻano sandwich, me ka mea hoʻomālamalama e hana ana ma ke ʻano he papa mea kanu ma waenakonu. ʻO ke ʻano kikoʻī, ʻo ka ʻano hōʻike OLED he substrate (i hana pinepine ʻia me ka plastic moakaka a i ʻole ka foil metala no ke kākoʻo), kahi anode, kahi papa organik (me kahi papa conductive a me kahi papa emissive), a me kahi cathode. Hoʻohana pinepine ka papa conductive i nā polymers organik e like me ka polyaniline e lawe i nā lua, ʻoiai ʻo ka papa emissive e hoʻomaʻamaʻa i ka lawe ʻana o ka electron a me ka hoʻokuʻu ʻana o ka mālamalama.

Ma muli o ke ʻano hoʻokele, hiki ke hoʻokaʻawale ʻia nā pale OLED i nā ʻano matrix-active (AMOLED) a me nā ʻano passive-matrix (PMOLED). Hoʻolako ʻia nā OLED matrix-active me nā transistors ʻoniʻoni lahilahi (TFT), kahi e hōʻemi pono ai i ka hoʻohana ʻana i ka mana, ʻoiai ʻoi aku ka maikaʻi o nā OLED passive-matrix i kekahi mau ʻano hana. ʻAʻole e like me nā LCD, e pono ai kahi module backlight, ʻo ka pale OLED kahi mea hoʻopuka ponoʻī ʻaʻole pono i kahi backlight. Hoʻomaʻalahi kēia i kona ʻano a lawe mai i nā pono he nui, me nā kihi nānā ākea, nā manawa pane wikiwiki, kahi kaapuni hoʻokele maʻalahi, ka hana kala maʻalahi, a me ka hiki ke hoʻokō i nā ʻano panela maʻalahi a pelu.

Ma muli o nā kumumanaʻo hoʻolālā o ka māmā, ka lahilahi, ka pōkole, a me ka liʻiliʻi, kūpono loa ka ʻenehana OLED no nā panela liʻiliʻi a waena. Ua hoʻohana nui ʻia ia i nā mea pāʻani MP3, nā kelepona paʻalima, a me nā mea hana kikohoʻe like ʻole. ʻOiai aia kekahi mau huahana OLED i ke kahua hoʻolaha prototype a hōʻikeʻike paha a ʻaʻole i komo i ka hoʻohana piha ʻana, ua loaʻa i kā lākou mau ʻano hōʻike like ʻole ka ʻike nui ʻia ma ka ʻoihana. I ka wā e hiki mai ana, i ka hoʻomau ʻana o ka ʻenehana i ka oʻo ʻana, manaʻo ʻia e pani ka hōʻike OLED i nā pale LCD kuʻuna ma nā kahua hou aʻe a lilo i hopena hōʻike nui.
