Nrog rau txoj kev loj hlob sai ntawm niaj hnub mobile kev sib txuas lus technology thiab wireless Internet technology, lub ntiaj teb no tau nkag mus rau ib tug tshiab "hnub nyoog cov ntaub ntawv", thiab cov ntaub ntawv cov ntsiab lus yog nce ntau nplua nuj thiab muaj yeeb yuj. Raws li ib feem tseem ceeb ntawm cov ntaub ntawv kev lag luam, cov cuab yeej siv tau ib txwm ua lub luag haujlwm tseem ceeb hauv kev tsim cov ntaub ntawv thev naus laus zis.
Niaj hnub no cov zaub technologies yog qhov kawg thiab muaj ntau haiv neeg. Ntau yam khoom lag luam muaj nyob ib puag ncig peb, nqa ntau yam yooj yim rau peb txoj haujlwm thiab lub neej, thiab tseem coj tau qhov pom kev zoo dua.
1. LED
LED, lossis Lub Teeb Emitting Diode, yog cov khoom siv hluav taws xob hauv lub xeev uas tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb. Thaum lub LED raug rau ib tug pem hauv ntej bias voltage, electrons raug txhaj los ntawm N cheeb tsam mus rau P cheeb tsam thiab sib txuas nrog lub qhov los tsim electron-qhov khub. Cov electrons thiab qhov no tso tawm lub zog nyob rau hauv daim ntawv ntawm photons thaum lub sij hawm recombination txheej txheem. LED muaj cov yam ntxwv ntawm kev ua haujlwm siab, txuag hluav taws xob, kev tiv thaiv ib puag ncig, cov lus teb ceev ceev, siab ci thiab nplua nuj xim, thiab siv dav hauv teeb pom kev zoo, zaub thiab lwm yam. Muaj ob lub ntsiab kev siv ntawm LED zaub technology. Ib tug yog raws li lub backlight qhov chaw ntawm lub LCD los hloov lub qub CCFL (txias cathode fluorescent teeb), yog li ntawd lub LCD muaj cov yam ntxwv ntawm ultra-wide xim gamut, ultra-nyias tsos, lub zog txuag thiab kev tiv thaiv ib puag ncig; Qhov thib ob yog LED zaub screen, uas siv LED ncaj qha raws li cov khoom siv, tuaj yeem muab faib ua monochrome zaub thiab xim zaub. Nws muaj cov yam ntxwv ntawm lub siab ci, siab txhais thiab ci xim. Nws yog dav siv nyob rau hauv billboards, theem keeb kwm yav dhau, kis las venues thiab lwm yam sij hawm.
2. OLED npo
OLED yog Organic Light Emitting Diode (Organic Light Emitting Diode), tseem hu ua organic electric laser zaub thiab organic teeb-emitting semiconductor. Nws yog cov khoom siv organic semiconductor thiab cov khoom siv luminescent uas emits lub teeb los ntawm kev txhaj tshuaj thiab recombination ntawm cov cab kuj nyob rau hauv kev tsav tsheb ntawm hluav taws xob teb. Nws yog hom tam sim no. hom organic teeb-emitting li.
OLED yog hu ua lub cim thib peb cov khoom siv thev naus laus zis. Vim tias nws yog nyias, muaj zog siv tsawg, siab ci, zoo luminous tus nqi, tuaj yeem pom cov xim dub, thiab tuaj yeem khoov tau, OLED thev naus laus zis tau dhau los ua qhov tseem ceeb hauv TVs, saib, thiab xov tooj ntawm tes niaj hnub no. , ntsiav tshuaj thiab lwm yam teb tau dav siv.
3. QLED
QLED, Quantum Dot Light Emitting Diode (Quantum Dot Light Emitting Diode), yog lub teeb-emitting tshuab raws li quantum dots. Lub quantum dot txheej yog muab tso rau hauv nruab nrab ntawm lub electron thauj thiab lub qhov thauj cov organic cov ntaub ntawv txheej, thiab ib tug sab nraud hluav taws xob teb yog siv los mus tshem tawm cov electrons thiab qhov. mus rau hauv quantum dot txheej, thiab ces electrons thiab qhov recombine kom emit teeb. Tus qauv ntawm QLED zoo ib yam li OLED. Qhov sib txawv tseem ceeb yog cov khoom siv hluav taws xob ntawm QLED yog inorganic quantum dot khoom, thaum OLED siv cov khoom siv organic. QLED muaj cov yam ntxwv ntawm lub teeb emission, siab luminous efficiency, ceev teb ceev, adjustable spectrum, dav xim gamut, thiab lwm yam. Nws yog ruaj khov thiab muaj lub neej ntev dua OLED. Muaj ob hom kev thov tseem ceeb ntawm QLED thev naus laus zis. Ib qho yog quantum dot backlight technology raws li cov khoom siv photoluminescence ntawm quantum dots, uas yog, ntxiv quantum dots rau lub backlight ntawm LCD los txhim kho xim luam thiab ci; Lwm qhov yog quantum dot backlight technology. Quantum dot light-emitting diode display technology raws li cov khoom siv electroluminescence ntawm quantum dots, uas yog, quantum dots yog sandwiched ntawm electrodes kom ncaj qha emit lub teeb, txhim kho qhov sib piv thiab saib cov ces kaum. Tam sim no, QLED cov lus qhia raws li quantum dot backlight hom tau siv dav hauv khw. Lub npe hu ua "quantum dot TVs" nyob rau hauv kev ua lag luam yog qhov pib LCD TVs nruab nrog quantum dot films, thiab lawv cov ntsiab lus tseem yog LCD thev naus laus zis.
4. Mini LED
Mini LED yog sub-millimeter lub teeb emitting diode (Mini Light Emitting Diode), uas yog ib qho khoom siv LED nrog lub nti loj ntawm 50-200μm. Nws yog qhov tshwm sim ntawm kev ua kom zoo dua ntxiv ntawm cov teeb me me LEDs.
Cov ntawv thov ntawm Mini LED feem ntau muab faib rau hauv kev siv Mini LED chips li LCD backlight daws teeb meem thiab cov kev daws teeb meem rau tus kheej uas ncaj qha siv RGB peb-xim LEDs, uas yog, cov kev daws teeb meem rov qab thiab cov kev daws teeb meem ncaj qha. Mini LED backlight yog ib qho kev taw qhia tseem ceeb rau LCD thev naus laus zis hloov khoom dua tshiab, uas tuaj yeem txhim kho lub teeb LCD thiab qhov sib txawv tsaus nti thiab cov duab dynamic, yog li txhim kho qhov pom kev pom. Mini LED ncaj qha zaub tuaj yeem ua seamlessly spliced ntawm txhua qhov loj me, txhawb kev siv cov xwm txheej ntawm cov npo loj loj. Nws kuj tseem tuaj yeem txhim kho kev ua haujlwm zoo xws li qhov sib piv, xim qhov tob, thiab xim nthuav dav.
5. Micro LED
Micro LED, Micro Light Emitting Diode, tseem hu ua mLED lossis μLED, yog ib qho kev siv tshuab LED raws li qib micron. Nws shrinks LED chips mus rau qib micron thiab integrates lab ntawm lawv nyob rau hauv ib chav tsev. LED nti paub txog cov duab tso saib los ntawm kev tswj lub hauv thiab tawm ntawm txhua lub nti LED. Micro LED tuaj yeem hais tau los ua ke txhua qhov zoo ntawm LCD thiab OLED. Nws muaj cov txiaj ntsig tseem ceeb xws li kev daws teeb meem siab, kev siv hluav taws xob tsawg, lub teeb ci siab, qhov sib txawv siab, xim xim saturation, ceev teb, nyias thickness, thiab lub neej ntev. Txawm li cas los xij, tam sim no tab tom ntsib Cov txheej txheem tsim khoom yog qhov nyuaj thiab cov nqi tsim khoom yog siab.
Nyob rau hauv luv luv, lub lag luam Micro LED yog tsom rau ultra-me me qhia. Nyob rau hauv nruab nrab mus rau lub sij hawm ntev, Micro LED muaj ntau yam kev siv, spanning wearable li, loj nyob rau hauv tsev cov ntxaij vab tshaus, head-mounted displays (HMD), head-up displays (HUD), tsheb taillights, wireless optical kev sib txuas lus Li-Fi, thiab AR / VR, projectors thiab lwm yam teb.
6. Micro OLED
Micro OLED, tseem hu ua silicon-based OLED, yog cov khoom siv micro zaub raws li OLED thev naus laus zis. Nws siv cov txheej txheem siv lead ua silicon nkaus xwb thiab muaj cov yam ntxwv ntawm tus kheej teeb pom kev zoo, siab pixel ceev, me me, tsawg zog noj, siab sib piv thiab ceev teb ceev.
Qhov zoo ntawm Micro OLED feem ntau yog los ntawm kev sib xyaw ua ke ntawm CMOS thev naus laus zis thiab OLED thev naus laus zis, nrog rau qib siab ntawm kev koom ua ke ntawm inorganic semiconductor cov ntaub ntawv thiab cov ntaub ntawv organic semiconductor. Tsis zoo li cov ntxaij vab tshaus OLED ib txwm siv cov iav substrates, Micro OLEDs siv monocrystalline silicon substrates, thiab cov tsav tsheb sib txuas ncaj qha rau ntawm substrate, txo qhov tuab ntawm lub vijtsam. Thiab vim tias nws siv tshuab semiconductor, nws qhov sib nrug ntawm pixels tuaj yeem ua raws li qhov kev txiav txim ntawm ob peb microns, yog li ua kom tag nrho pixel ceev. Nws tuaj yeem nkag siab yooj yim xws li siv cov cuab yeej tsim khoom siv los tsim cov ntxaij vab tshaus.
Micro OLED thiab OLED yog qhov zoo sib xws hauv txoj cai. Qhov sib txawv loj tshaj ntawm lawv yog "Micro". Micro OLED txhais tau hais tias cov pixels me dua thiab tsim nyog rau kev siv me me, ua haujlwm siab, siab txhais cov khoom siv xws li head-mounted displays (HMD) thiab electronic viewfinders (EVF).
