AM OLED vs. PM OLED: He kaua o nā ʻenehana hōʻike
Ke hoʻomau nei ka ʻenehana OLED i ka mana o nā mea hoʻohana uila, hoʻoikaika ka hoʻopaʻapaʻa ma waena o Active-Matrix OLED (AM OLED) a me Passive-Matrix OLED (PM OLED). ʻOiai ke hoʻohana nei lāua ʻelua i nā diodes māmā māmā no nā hiʻohiʻona hiʻohiʻona, ʻokoʻa loa kā lākou hale hana a me nā noi. Eia ka wehewehe ʻana o kā lākou ʻokoʻa nui a me nā hopena mākeke.
ʻenehana kumu
Hoʻohana ʻo AM OLED i kahi transistor kiʻiʻoniʻoni lahilahi (TFT) backplane e hoʻomalu i kēlā me kēia pika ma o nā capacitors, hiki ke hoʻololi pololei a wikiwiki hoʻi. Hāʻawi kēia i nā ʻōlelo hoʻonā kiʻekiʻe, ʻoi aku ka wikiwiki o ka refresh rate (a hiki i 120Hz+), a me ka ʻoi aku ka maikaʻi o ka ikehu.
Ke hilinaʻi nei ʻo PM OLED i kahi ʻōnaehana māka maʻalahi kahi e nānā ʻia ai nā lālani a me nā kolamu no ka hoʻāla ʻana i nā pika. ʻOiai ʻoi aku ka maikaʻi o ke kumukūʻai, hoʻopaʻa kēia i ka hoʻonā a me ka hōʻoluʻolu ʻana, e kūpono ana i nā hōʻike liʻiliʻi liʻiliʻi.

Nā Noi Makeke a me nā Manaʻo ʻOihana
Ke hilinaʻi nei nā kelepona ʻo Samsung Galaxy, Apple's iPhone 15 Pro, a me LG's OLED TV ma AM OLED no kona pololei kala a me ka pane. Kuhi ʻia ka mākeke AM OLED honua a hiki i $ 58.7 biliona e 2027 (Allied Market Research).Loaʻa i nā mea hoʻoikaika kino haʻahaʻa, nā HMI ʻoihana, a me nā hōʻike kiʻekiʻe. Ua hōʻole ka hoʻouna ʻana i 12% YoY i 2022 (Omdia), akā hoʻomau ka noi no nā polokalamu ultra-budget.ʻAʻole hoʻohālikelike ʻia ʻo AM OLED no nā hāmeʻa premium, akā ʻo ka maʻalahi o PM OLED e mālama pono i nā mākeke e kū mai ana. ʻO ka piʻi ʻana o nā foldables a me AR / VR e hoʻonui i ke āpau ma waena o kēia mau ʻenehana.
Me ka AM OLED e neʻe nei i loko o nā pale ʻōwili a me nā microdisplays, ke alo nei ʻo PM OLED i ka obsolescence ma waho o nā niches ultra-low-power. Eia nō naʻe, ʻo kāna hoʻoilina ma ke ʻano he hopena OLED pae komo e hōʻoia i ke koena o ka noi ma IoT a me nā dashboard kaʻa.
