AM OLED vs. PM OLED: Kev Sib Ntaus Sib Tua ntawm Cov Txuj Ci Zaub

Raws li cov thev naus laus zis OLED txuas ntxiv tswj hwm cov khoom siv hluav taws xob rau cov neeg siv khoom, kev sib cav sib ceg ntawm Active-Matrix OLED (AM OLED) thiab Passive-Matrix OLED (PM OLED) nce ntxiv. Txawm hais tias ob qho tib si siv cov diodes teeb pom kev zoo rau cov duab ci ntsa iab, lawv cov qauv thiab cov ntawv thov sib txawv heev. Nov yog kev rhuav tshem ntawm lawv qhov sib txawv tseem ceeb thiab cov txiaj ntsig ntawm kev ua lag luam.

                                               Cov Txuj Ci Tseem Ceeb
AM OLED Siv lub transistor nyias-zaj duab xis (TFT) backplane los tswj txhua lub pixel ntawm cov capacitors, ua kom muaj kev hloov pauv sai thiab meej. Qhov no tso cai rau kev daws teeb meem siab dua, cov nqi refresh sai dua (txog li 120Hz +), thiab kev siv hluav taws xob zoo dua.

PM OLED siv lub grid system yooj yim dua uas cov kab thiab kem raug scanned ua ntu zus kom ua haujlwm pixels. Txawm hais tias tus nqi tsim nyog, qhov no txwv qhov kev daws teeb meem thiab cov nqi refresh, ua rau nws haum rau cov zaub me me, tsis hloov pauv.

                                 Kev Sib Piv Txog Kev Ua Tau Zoo            

             Cov Kev Siv Lag Luam thiab Kev Pom Kev Lag Luam

Cov xov tooj ntse Galaxy ntawm Samsung, Apple lub iPhone 15 Pro, thiab LG lub OLED TVs vam khom AM OLED rau nws qhov tseeb ntawm xim thiab kev teb tau zoo. Kev lag luam thoob ntiaj teb AM OLED kwv yees tias yuav ncav cuag $ 58.7 billion los ntawm xyoo 2027 (Allied Market Research).Pom muaj nyob rau hauv cov cuab yeej ntsuas kev noj qab haus huv pheej yig, HMIs kev lag luam, thiab cov zaub thib ob. Kev xa khoom poob qis 12% YoY hauv xyoo 2022 (Omdia), tab sis qhov kev thov tseem muaj rau cov khoom siv pheej yig heev.AM OLED tsis muaj leej twg piv tau rau cov khoom siv zoo tshaj plaws, tab sis PM OLED qhov yooj yim ua rau nws tseem ceeb rau cov lag luam tshiab. Kev nce ntawm cov khoom siv uas muaj peev xwm quav tau thiab AR / VR yuav ua rau qhov sib txawv ntawm cov thev naus laus zis no dav dua.                                                  

Nrog AM OLED nce mus rau hauv cov ntxaij vab tshaus dov tau thiab microdisplays, PM OLED ntsib teeb meem qub dhau lawm sab nraud ntawm cov niches ultra-low-power. Txawm li cas los xij, nws qhov qub txeeg qub teg ua qhov kev daws teeb meem OLED theem pib ua kom muaj kev thov seem hauv IoT thiab automotive dashboards. Thaum AM OLED kav zoo tshaj plaws hauv cov khoom siv hluav taws xob siab, PM OLED qhov zoo dua tus nqi ua kom nws lub luag haujlwm hauv cov kev lag luam tshwj xeeb - tam sim no.
