Yuav ua li cas LCD zaub vaj huam sib luag ua haujlwm tau piav qhia

Saib ntawm koj lub LCD, tej zaum koj yuav xav tsis thoob yog tias cov neeg ua haujlwm me me nyob sab hauv, tig pixels rau thiab tawm thaum koj tsis pom qhov "magic screen." Koj tsis nyob ib leeg-LCD thev naus laus zis feem ntau xav zoo li tsis meej pem, blinking khawv koob.

Txhawm rau txhim kho qhov ntawd, peb rhuav cov LCDs rau hauv qhov yooj yim: cov kua siv lead ua kua, cov ntxaij lim dej, thiab cov teeb pom kev zoo ua haujlwm ua ke. Kawm cov hauv paus ntsiab lus thiab koj yuav thaum kawg "pom" cov duab tsim li cas. Txhawm rau kom nkag siab tob dua, tshawb xyuas cov ncauj lus kom ntxaws IEEE:https://spectrum.ieee.org/how-lcds-work.

🔧 Basic Structure of LCD Panels: Layers, Liquid Crystals, thiab Backlight

LCD panels siv txheej txheej iav, kua siv lead ua kua, lim, thiab lub teeb rov qab. Ua ke cov khaubncaws sab nraud povtseg tswj lub teeb kom tsim cov duab ntse, ruaj khov nrog kev siv hluav taws xob tsawg.

Txhua txheej muaj lub luag haujlwm meej: coj lub teeb, tig nws, lossis thaiv nws. Cov vaj huam sib luag zoo ua haujlwm zoo-kho txhua txheej rau qhov ci, qhov sib txawv, thiab lub neej ua haujlwm ntev.

1. Pem hauv ntej iav thiab Polarizer

Lub iav pem hauv ntej tuav lub polarizer uas tsuas yog cia lub teeb nrog ib qho kev taw qhia dhau mus. Thawj lim dej no pib cov txheej txheem ntawm kev tswj lub teeb hauv LCD.

• Tiv thaiv cov khaubncaws sab nraud povtseg
• Teeb pom kev taw qhia thawj zaug
• Txo qhov glare nto

2. Kua Crystal Txheej

Cov kua ua kua twist thaum lawv xav tias muaj hluav taws xob. Qhov kev sib tw no hloov pauv li cas lub teeb hla dhau, uas tig ib tus pixels rau lossis tawm.

3. Xim Lim thiab TFT iav

Lub iav nram qab tuav nyias-zaj duab xis transistors thiab xim lim. Txhua lub transistor tswj lub subpixel, thaum cov ntxaij lim dej txhais cov xim liab, ntsuab, lossis xiav xim.

• Cov qib grey ruaj khov
• Lub sij hawm teb ceev ceev

2. Greyscale thiab Dimming

Los ntawm kev hloov voltage hauv cov kauj ruam me me, lub vaj huam sib luag tsim ntau qib grey. Cov qib no sib xyaw nrog cov xim lim kom tsim cov gradients du.

3. Hais txog kab thiab kab

Tsav ICs scan kab thiab pub kab nrawm heev. Cov kab-kem no hais txog teeb txhua pixel yam tsis pom flicker rau tib neeg lub qhov muag.

• Kab tsav tsheb xaiv kab
• Kem tsav tsheb xa cov ntaub ntawv
• Refresh rov ua dua ntau zaus hauv ib ob

🌈 Xim Lim thiab Subpixels: Tsim Tag Nrho - Xim Duab Los Ntawm Lub Teeb Dawb

Txhua pixel faib ua liab, ntsuab, thiab xiav subpixels. Cov xim lim dej thiab qib voltage muab cov no los tsim ntau lab xim los ntawm lub teeb dawb.

Kev tswj xyuas meej ntawm txhua qhov subpixel qhov ci ci muab cov xim raug, cov ntawv ntse, thiab cov npoo huv, uas yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua haujlwm pom.

1. RGB Subpixel Layout

Peb subpixels zaum ib sab: ib tug liab, ib ntsuab, ib xiav. Ua ke lawv ua ib qho pom pixel rau koj lub qhov muag.

• Standard RGB kab txaij
• Qee cov vaj huam sib luag siv RGBW
• Layout cuam tshuam rau sharpness

2. Kev sib xyaw xim los ntawm kev siv lub teeb

Sib txawv lub teeb los ntawm txhua RGB subpixel sib xyaw xim. High-end LCDs ua kom qhov sib xyaw no ruaj khov nyob thoob plaws qhov pom dav thiab qhov kub thiab txias.

3. Xim raug rau kev lag luam siv

Industrial TFTs yuav tsum ua kom cov xim ruaj khov nyob rau lub sijhawm. Qhov no pab cov neeg ua haujlwm nyeem lub tswb, kab kos, thiab cov duab tsis muaj qhov yuam kev lossis qhov muag tsis pom.

• Kev xaiv dav xim gamut
• Hoobkas xim calibration
• Temperature-stable kua crystals
