Daim ntawv thov thiab ua haujlwm ntawm txoj cai ntawm dodes hauv smartphones

1, tus txheej txheem tseem ceeb ntawm diodes
Ib qho Diode, tseem hu ua PN Junction Diode, yog lub cuab yeej semiconduct nrog ob electrodes (anode thiab cathode). Nws yog tsim ntawm n - Hom semiconductor thiab p} Hom sandiconductor cov ntaub ntawv, txuas nrog ua ke los ntawm p- n hlws. Tus yam ntxwv ntawm P -} nws yog nws tuaj yeem tsim cov unidirectional creams. Thaum lub qhov zoo hauv p - Hom semiconductors ua ke nrog cov tshuab hluav taws xob tsis zoo nyob rau hauv n} yuav them, tsim ib txoj hauv kev ntws tawm. Thaum xa rov qab (nrog cov hluav taws xob siab ntawm lub Pierinal thiab qis volinal nyob rau ntawm N lub davhlau ya nyob twg), Diode nyob hauv lub xeev uas ua, tso cai ntws mus; Thaum thim rov qab (nrog rau cov voltage qis ntawm lub P Terminal thiab siab voltage ntawm N lub davhlau ya nyob twg), Diode yog nyob rau hauv ib tug txiav- tawm xeev, tiv thaiv kev ntws tam sim no.
2, daim ntawv thov ntawm dodes nyob rau hauv smartphones
Smartphones sib xyaw ua ke ntau ntawm cov hluav taws xob hluav taws xob sab hauv, nrog diodes ua si ntau lub luag haujlwm, suav nrog tab sis tsis txwv rau cov hauv qab no:
Rectification Love: Hauv lub zog tswj hwm ntawm cov smartphones, diodes feem ntau siv los ua rectifiers kom hloov pauv hloov tam sim no. Nov yog lub hauv paus ntawm cov roj teeb xov tooj ntawm tes them thiab sab hauv fais fab hluav taws xob. Kev xaiv thiab tsim cov rectifier diodes yog qhov tseem ceeb rau kev txhim kho kev them nyiaj ua haujlwm thiab lub zog ruaj khov.
Kev tiv thaiv Circuit: Diodes hauv Smartphones tseem pabcuam los tiv thaiv lub voj voog. Piv txwv li, hauv hluav taws xob hluav taws xob tawm tsam Circuit Coack, zoo ib yam dab tsi yuav tiv thaiv cov pej xeem kev puas tsuaj los ntawm kev thim rov qab ntawm lub zog hluav taws xob. Tsis tas li ntawd, nyob rau hauv kev tiv thaiv kev tiv thaiv kev tiv thaiv, voltage regulators lossis zenerage diodes lossis zenering descuitated peaktionents los ntawm kev puas ntsoog vim muaj kev tiv thaiv.
Kev Pib Ua Si: Hauv RF Circuit Coad ntawm Smartphones, Lub Tsheb Loj Npaum Li Cas Hluav Taws Xob Los Ntawm Kev Hloov Pauv Los Ntawm Hloov Lawv Tus Nqi Peev Xwm, yog li ua kom tiav kev tawm tsam ntawm RF cim. Qhov no yog qhov tseem ceeb rau kev txhim kho kev sib txuas lus zoo thiab kev ruaj khov ntawm lub xov tooj txawb. Ib qho ntxiv, diodes kuj tau siv los tshem tawm suab, sib cais kev sib txuas lus hauv cov sib txawv, thiab lwm yam.
Tso cov thev naus laus zis: Txawm hais tias Diodes tsis ncaj qha rau cov zaub screen ntawm smartphones, lawv tseem ua lub luag haujlwm indirephones, lawv tseem ua lub luag haujlwm ua haujlwm ncaj qha hauv cov khoom siv thev naus laus zis. For example, in liquid crystal display (LCD) technology, backlight systems typically include light-emitting diodes (LEDs) to provide uniform illumination to the screen. Cov diodes coj tsis tsuas yog txhim kho qhov ci thiab xim ua tau zoo ntawm lub vijtsam, tab sis kuj txo hluav taws xob tau.
Kov Technology: Hauv lub kov npo ntawm cov smartphones, txawm tias nws tsuas yog tso siab rau lub peev xwm ntawm kev pom zoo, diodes tseem ua lub luag haujlwm thiab tswj cov kab sib txuas. Lawv pab kom ua kom nrov dua, cov duab, thiab xa cov paib kov, li kev txhim kho kov cov rhiab thiab raug.
3, Cov piv txwv tshwj xeeb ntawm donges hauv smartphones
Schottky diodes: Schottky diodes tau siv dav hauv lub siab {{0} Kev tswj lub zog thiab lub zog hluav taws xob rov qab los thiab qis dua voltage poob. Piv txwv li, hauv xov tooj txawb Chargers, Schottky diodes yog lub luag haujlwm kom nrawm nrawm tam sim no, txhim kho kev them nyiaj ua haujlwm thiab txo cov cua sov. Tsis tas li ntawd, Scottky diodes tseem ua si lub luag haujlwm tseem ceeb hauv kev hloov cov khoom siv hluav taws xob, kom meej ruaj khov voltage tso thiab hluav taws xob kev ua tau zoo thiab hluav taws xob kev ua tau zoo thiab hluav taws xob hluav taws xob.
Lub teeb qhib diodes (LEDs): LED diodes muab kev txhim khu kev qha thiab ua kom haum rau cov teeb cartphone, thiab koob yees duab backarding, thiab koob yees duab. Cov coj tsis tsuas yog muaj qhov zoo ntawm kev siv fais fab tsis tshua muaj, lub neej ntev ntev, tab sis kuj tuaj yeem muab cov ntaub ntawv sib txawv los ntawm cov xim sib txawv thiab flashing qauv.
Kev sib xyaw ua ke Diode: ib qho kev sib xyaw ua ke DIode muab ntau yam dodes dodes ua ke kom ua tiav cov haujlwm nyuaj dua. Piv txwv li, kev sib xyaw ua ke ntawm cov ntxaij lim dej xws li cov ntxaij lim dej qis, thiab cov ntaub lim dej uas muaj cov suab paj nruag, thiab cov paib sib txuas, thiab txhim kho kev sib txuas lus zoo. Cov ntxaij lim dej yog cov hluav taws xob tsim tau ntawm capacitors, inductors, thiab lwm yam uas tsim ntau qhov chaw sib txawv, yog li ua tiav cov paib kev lim thiab ua tiav.
4, qhov sib txheeb ntawm kev ua haujlwm ntawm txoj cai ntawm dodes thiab kev ua haujlwm ntawm cov smartphones
Tus ua haujlwm ua haujlwm ntawm diodes yog ze ze rau kev ua haujlwm ntawm cov smartphones. Firstly, los ntawm kev tswj hwm cov kev taw qhia thiab qhov ntau ntawm cov tam sim no, tus dev ua haujlwm rau kev ua haujlwm ruaj khov ntawm sab hauv lub xov tooj ntawm lub smartphone. Piv txwv li, hauv lub hwj chim tswj hwm cov tshuab, kev ua haujlwm zoo ntawm Rectifier dodes kev ua haujlwm tau zoo thiab roj teeb lub neej. Thib ob, lub luag haujlwm ntawm dodes hauv kev tiv thaiv cov voj voog tiv thaiv kev puas tsuaj los ntawm cov khoom siv xws li overvoltage thiab overcurrent, yog li txuas ntxiv rau lub neej ntawm cov xov tooj ntawm smartphones. Ib qho ntxiv, daim ntawv thov ntawm diodes nyob rau hauv RF circuits thiab tso duab thev naus laus zis tau txhim kho kev sib txuas lus zoo thiab pom ntawm cov smartphones, txhim kho cov neeg siv kev paub.
