3.98 Nti TFT LCD Module

 

ENH-TV0398A002Kev piav qhia

 

Cov3.98 Nti TFT LCD Modulezaum hauv qhov chaw qab zib uas ob peb qhov ntau thiab tsawg tuaj yeem thov tau -loj txaus los qhia cov ntaub ntawv muaj txiaj ntsig ntawm ib sab, tsis tau compact txaus kom haum rau hauv cov khoom siv kho mob, kev tswj vaj huam sib luag, thiab kev sib txuas hauv tsev ntse. Tom qab xa khoom ntau txhiab ntawm cov chav no, kuv tuaj yeem qhia koj raws nraim qhov nws ua tau zoo thiab qhov twg nws tsis.

Peb3.98 Nti TFT LCD Moduleyog tsim nyob ib ncig ntawm ST7796U tsav IC, uas tau dhau los ua ib yam dab tsi ntawm cov neeg ua haujlwm hauv 320x480 qhov chaw. Lub 8-LED parallel backlight muab 320 cd / m² qhov ci ci, thiab IPS vaj huam sib luag muab cov kaum sab xis uas muaj teeb meem thaum ib tus neeg saib ntawm lub vijtsam los ntawm sab ntawm lub txaj hauv tsev kho mob lossis hauv pem teb hauv tsev.

Cia kuv taug kev koj los ntawm qhov tseem ceeb ntawm cov qauv no - tsis yog daim ntawv teev npe kev lag luam, tab sis kev txiav txim siab engineering uas cuam tshuam rau nws ua haujlwm li cas hauv ntiaj teb tiag.

 

Cov ntsiab lus Parameter Analysis

320 × 480 daws teeb meem.Ntawm 3.98-inch kab pheeb ces kaum, 320 × 480 xa kwv yees li 145 PPI. Qhov ntawd tsis yog retina-chav kawm, tab sis rau cov khoom siv saib ntawm 30–50 cm-xav tias cov khoom siv kho mob, HMIs muaj, thiab cov vaj huam sib luag hauv tsev ntse-nws yog qhov tsim nyog. Qhov tseem ceeb tshaj, nws yog qhov kev daws teeb meem uas ua haujlwm zoo ntawm cov microcontrollers nruab nrab. Lub thav duab tsis rau RGB565 xim qhov tob tsuas yog tshaj 307,000 bytes, uas haum zoo nyob rau hauv RAM ntawm ESP32 lossis STM32 yam tsis muaj lub cim xeeb sab nraud.

ST7796U Tsav IC.ST7796U txhawb nqa 320 × 480 daws teeb meem ntawm 60Hz refresh npaum li cas, ua tau raws li cov lus pom zoo tshaj plaws xws li cov ntawv nyeem thiab cov duab yooj yim. Nws suav nrog ua- hauv kev kho vajtse acceleration functions xws li scrolling thiab cursor tswj. Dab tsi ntawm cov ntaub ntawv tsis qhia meej txaus yog qhov ecosystem-ST7796U tau txais kev txhawb nqa los ntawm TFT_eSPI, LVGL, thiab Adafruit cov tsev qiv ntawv duab. Peb muab cov lej pib pib rau STM32, ESP32, thiab Arduino, txhua qhov kev sim hauv ntau lawm.

Lub 8-LED Backlight.Yim LEDs nyob rau hauv parallel, txhua daim duab 20 mA, xa 320 cd / m² nrog cov teeb pom kev zoo nyob thoob plaws 92.25 × 60 mm tus qauv. Vim li cas 8 LEDs hloov 4? Vim tias cov vaj huam sib luag loj xav tau ntau qhov teeb pom kev zoo kom tsis txhob muaj qhov tsaus ntuj. Peb tau kawm qhov no los ntawm cov neeg siv khoom siv kho mob uas yws yws txog qhov tsis sib xws ntawm lub teeb ci ntawm 4-LED tsim. Lub 8-LED teeb tsa daws qhov teeb meem no tag nrho.

Polarizer pawg.Upper matte 0℃txo qhov glare los ntawm cov teeb pom kev zoo ntawm lub taub hau- tseem ceeb hauv cov chav tsev kho mob thiab cov chaw tswj kev lag luam. Lower glossy 90℃maximizes lub teeb kis tau los ntawm lub vaj huam sib luag. Qhov kev sib xyaw ua ke no ua tiav qhov sib piv 1000: 1, nrog cov xim dub tob thaum pixels tawm.

Xim Coordinates.X: 0.25 ± 0.03, Y: 0.26 ± 0.03. Qhov ntawd yog ib qho teeb meem dawb sib xws hauv cov khoom tsim khoom. Rau cov khoom siv kho mob uas qhia cov xim- cov duab kuaj mob tseem ceeb, qhov sib xws no tseem ceeb. Peb ntsuas txhua batch.
