 Vim li cas koj cov LED zaub xim distorted?

 

 

 

 

Xim xim distortion nyob rau hauv LED qhia txog qhov tsis sib xws ntawm cov xim tso tawm ntawm qhov screen thiab daim duab qub lossis lub ntiaj teb tiag tiag. Qhov teeb meem no tuaj yeem tshwm sim ua cov xim hloov, tsis meej, tsis sib luag, lossis qhov tsis sib xws hauv cov laus tag nrho. Nws tuaj yeem tshwm sim los ntawm cov khoom siv kho vajtse kho, teeb meem tsis raug, teeb meem kis tau, ib puag ncig kev cuam tshuam, lossis kho kev saib xyuas tsis zoo.

 

I. Cov khoom kho vajtse muaj feem cuam tshuam ntawm xim distortion

 

LED teeb zoo thiab xwm yeem

 

Kev hloov pauv hauv cov yam ntxwv emission: LED teeb yuav txawv nyob rau hauv wavelength (chaw ua haujlwm xim), luminance (teeb meem tso zis), thiab xim kub ntawm cov kab sib txawv lossis cov qauv. Piv txwv li, lub nthwv dej hloov pauv tuaj yeem ua rau lub vijtsam liab tuaj yeem ua rau pom cov txiv kab ntxwv lossis ntshav, thaum tsis muaj qhov ci ntsa iab yuav ua rau cov duab tag nrho tshwm sim Cyan.

Kev laus thiab kev ua phem: Lub luminous efficiency ntawm LED teeb txo dhau lub sijhawm, thiab cov xim liab, thiab cov xim xiav tuaj yeem txwv ntawm cov nqi sib txawv. Kev siv lub sijhawm ntev yuav ua rau liab liab liab ua rau muaj kev cuam tshuam, lossis xiav coj cov teeb meem daj, ua rau daj-liab tint.

Tus tsav tsheb tsis txaus thev naus laus zis: Kev ruaj khov ntawm cov zis tsis tu ncua los ntawm cov tsav tsheb ncaj qha cuam tshuam rau kev ci ntsa iab. Yog tias Chip Precision yog qhov tsawg lossis tam sim no hloov pauv, kev hloov pauv tam sim no ntawm cov teeb pom kev zoo ib yam hauv tib qho kev sib tw xim lossis tawv nqaij.

 

Backlight qauv teeb meem

 

Kev sib txuam ntawm Backlight Modules: Uneven teeb hluav taws xob hauv LED Backlight modules tuaj yeem ua rau thaj chaw hauv zos kom muaj kev ci ntsa iab los yog sab. Piv txwv li, nyob rau hauv cov backlights, ntau dhau ntawm cov leds lossis cov qauv tsim nyob rau hauv cov phiaj xwm lub teeb pom kev yuav ua rau muaj kev ci ntsa iab tau, cuam tshuam kev ua yeeb yam.

 

Circuit Court thiab Kev Tsim Qauv Hluav Taws Xob

 

Lub Hwj Ceeb Muab Kev Ruaj Ntseg: Voltage hloov pauv hauv lub zog hluav taws xob tuaj yeem cuam tshuam rau kev tsav tam sim no ntawm LED teeb, ua rau ci ntsa iab, ua rau muaj kev ci ntsa iab lossis xim tsis ruaj khov.

Tsis zoo kub dissipation: Kev ntsuas kub siab nrawm nrawm nrawm nrawm thiab tuaj yeem ua rau cov kev saib xyuas Circuitans lossis cov kev sib koom tes rau cov teeb liab.

 

Ii. Software thiab tswj hwm cov laj thawj ntawm xim distortion

 

Tsis xws luag nyob rau hauv cov xim tswj cov tshuab

 

Uncalibrated lossis tsis muaj tseeb calibration: Tsis txhob ua yeeb yam kev txheeb xyuas kev ntsuas lossis siv cov khoom siv qis-precision calibration cov khoom siv tuaj yeem ua rau tsis txaus ntseeg RGB thawj xim xim sib piv. Piv txwv li, ntau ntau cov channel ntau dhau yuav ua rau lub vijtsam kom tshwm ntsej muag dua, thaum tsis txaus ntsuab yuav ua rau muaj magenta zas.

Tsis Yog Gamma Curve nqis: Gamma qhov tseem ceeb txiav txim siab tias kev hloov pauv ntawm lub teeb thiab qhov tsaus ntuj hauv cov duab. Yog tias tus nqi gamma tau teeb tsa ntau dhau, cov ntsiab lus tsaus ntuj yuav ploj, txo cov xim txheej loj; Yog tias qhov teeb meem qis dhau, thaj chaw kaj me me yuav tau txais kev ua kom tiav, ua rau cov xim txawv txav.

 

Cov duab tsis txaus ua cov txheej txheem zauv

 

Xim Chaw Mapping Yuam Kev: Yog tias lub vijtsam ua xim ua xim (piv txwv li, SRGB, Adobe RGB) tsis tau nqa tawm cov paib hloov dua siab tshiab tsis tau ua tiav, cov xim yuav tshwm sim distorted lossis ploj. Piv txwv li, cov liab liab heev yuav tshwm kab txiv kab ntxwv rau ntawm txoj kev nqaim-gamut.

Dynamic sib txawv algorithm teeb meem: Qee cov ntxaij vab tshaus hloov kho kev hloov kho cov chaw nyob ntau dhau los yog cov chaw tsaus nti, ua rau cov xim tsaus nti. Piv txwv li, dhau los ua kev ua thaum lub sijhawm HDDR cov ntsiab lus yuav ua rau muaj xim xim banding.

 

Tswj software swb

 

Cov teeb liab tsis raug: Yog hais tias lub tswv yim teeb tsa kev daws teeb meem, tus lej nqi, lossis cov chaw xim sib xws (piv txwv li, cov duab yuav raug compressed lossis ncab, ua rau xim distortion. Piv txwv li, pub {10- ntsis xim qhov tob teeb liab rau hauv ib qho kev ntsuas phoo video yuav ua rau xim banding.

Cov kab software ntsuab lossis cov khoom siv tsis xws luag: Cov yoov hauv cov tswj software uas yuav ua rau tsis muaj tseeb ntawm cov ntaub ntawv xim, ua rau muaj xim rau thaj chaw lossis cov khoom tawg. Piv txwv li, Outdated Firmware yuav tsis txhawb tus qauv xim kawg.

 

III. Kev xa tawm ntawm tes taw thiab cov teeb meem sib cuam tshuam rau xim distortion

 

Kev cuam tshuam ntawm kev cuam tshuam rau kev tawm tsam thiab ua kom pom

 

Kev Cuam Tshuam Electromagnetic Interregort (EMI): Muaj zog rau cov hluav taws xob (piv txwv li, los ntawm cov kab hluav taws xob high ntawm cov xov tooj cua siab Piv txwv li, HDMI cov cim yuav ua rau muaj kev sib ntsib lossis cov xim xim hauv cov chaw muaj zog eli ib puag ncig.

Cov teeb liab tsis zoo: Cov teeb liab tsis muaj txiaj ntsig yuav raug kev txom nyem los ntawm kev tsis sib haum xeeb, tsis muaj kev tiv thaiv lossis kev laus, ua rau lub teeb liab kev ua haujlwm lossis kev xav. Piv txwv li, siv tsis-fiber ntau HDMI cables rau kev sib tw ntev yuav ua rau lub teeb liab ploj thiab cov xim greyish tint.

 

Interface muaj teeb meem

 

Raws Raws Txoj Cai Mismatch: Yog tias cov ntaus ntawv tawm tswv yim thiab tshuaj ntsuam siv intracle sib txuas lus (piv txwv li HDMI 1.4 vs. Piv txwv li, HDMI 1.4 txhawb nqa tsuas 8- me ntsis qhov tob, yog li} me ntsis cov paib yuav muaj compressed.

Kev Tiv Thaiv Tsis Zoo lossis Oxidation: Xiav, oxidized, lossis plua plav cuam tshuam yuav cuam tshuam kev kis teeb liab, ua rau flickering, xim duab sab, lossis cov ntxaij vab tshaus. Piv txwv li, oxidized pins hauv DVI interface yuav ua rau ploj ntawm RGB paib.

 

IV. Ib puag ncig qhov ua rau muaj xim distortion

 

Teeb pom kev zoo

 

Huab cua lub teeb kev cuam tshuam: Lub teeb lub teeb pom kev zoo (piv txwv li, tshav ncaj qha) tuaj yeem ua kom pom kev ntsuas screen, txo cov xim sib piv. Conversely, High Screen Brightness nyob rau hauv ib puag ncig qis yuav ua rau muaj kev nkees nkees lossis xim pom kev sib txawv.

Xim kub misthing: Yog tias cov huab cua kub ntawm ambient lub teeb (piv txwv li, sov daj) sib txawv los ntawm lub vijtsam xim kub), nws yuav ua rau pom kev sib txawv ntawm cov xim sib txawv. Piv txwv li, saib cov ntsiab lus txias-toned nyob rau hauv ib qho chaw sov sov uas yuav ua rau nws tshwm sim xiav.

 

Qhov kub thiab cua sov

 

Kev Kub Siab: Kev ntsuas kub siab yuav ua kom nrawm dua LED, txo cov luminous efficiency thiab xim xim. Piv txwv li, sab nraum zoov LED Screen yuav tshwm sim daj nyob rau lub caij ntuj sov vim muaj kub.

Siab vaum: Cov chaw ib puag ncig huab yuav ua rau Circuit Coiluectrits, corrosion, lossis hws sab hauv LED teeb, cuam tshuam rau cov cim xa khoom ruaj khov. Piv txwv li, cov ntxaij vab tshaus sab hauv yuav flicker thaum lub caij muaj dej hiav txwv zoo li lub caij los nag.

 

V. Kev Siv thiab Cov Lus Qhia Txog Kev Pab Ua Rau Xim Distortion

 

Kev Siv Tsis Raug Cai

 

Cov chaw teeb ci ntau heev: Lub sijhawm ua haujlwm ntev ntawm cov qib siab zoo yuav ua rau muaj kev laus LED, ua rau xim distortion. Piv txwv, cov ntxaij vab tshaus sab nraum zoov tau teeb tsa rau kev pom ntau dhau yuav ua rau lub teeb ua kom ntev.

Cov duab ntev heev: Ua kom pom cov duab tib yam (piv txwv li, lub logo) rau ncua ntev yuav ua rau muaj kev kub ntxhov ntawm cov coj, kev laus sai sai. Piv txwv li, Khw Khw Tshaj Tawm Cov Duab Tshaj Tawm Zoo Li Cas tuaj yeem tsim cov xim thaj chaw xim.

 

Kev Txij Nkawm Tsis Txaus

 

Hmoov av ntxiv: Hmoov rau ntawm lub vijtsam nto lossis sab hauv tej zaum yuav txo kev hloov chaw teeb pom kev, ua rau cov xim ua kom pom siav. Piv txwv li, tsis muaj cov ntxaij vab tshaus sab nraum zoov yuav tshwm sim greyish vim plua plav kev pab them nqi.

Tsis muaj kev ntsuas tsis tu ncua: Screen Cov teeb meem xim yuav hloov tau dhau sijhawm, thiab yog tias tsis muaj teeb meem sai, xim teeb meem distortion teeb meem yuav cuam tshuam. Piv txwv li, xinesmas Cov ntxaij vab tshaus yuav tsum muaj kev ntsuas tsis tu ncua kom muaj xim sib xws.
