Cov txuj ci yooj yim ntawm LED zaub

2020/12/22

One.Classification ntawm LED cov ntxaij vab tshaus

Nyob sab hauv tsevCov zaub LEDtuaj yeem siv rau hauv qhov chaw nyob sab hauv. Lub vijtsam tso tawm no muaj lub teeb pom kev nruab nrab, pom Lub kaum ntse ntse loj, kaw cov xim sib xyaw, lub teeb yuag thiab lub teeb siab. Nws yog tsim rau pom ze.

Outdoor Cov zaub LED Outdoor Cov zaub LED is used in outdoor environment, such display screen has high brightness, long color mixing distance, high protection level, strong waterproof and anti-ULTRAVIOLET ability, suitable for remote viewing.

Tso Saib Xim Ib leeg-ximCov zaub LED Single-color Cov zaub LED consists of LED lights of one color and can only display a single color, such as red, green, orange, etc.

Dual-color Cov zaub LED Dual-color Cov zaub LED consists of red and green LED lights. The 256-level grayscale dual-color display can display 65,536 colors (dual-color display can display red, green and yellow).

Full color Cov zaub LED Full color Cov zaub LED consists of red, green and blue LED lights. It can display white balance and 16,777,216 colors.

Display function Text Cov zaub LED (asynchronous screen) text Cov zaub LED can display text, graphics and pictures and other information content.Networkable offline display.

Video Cov zaub LED (synchroscreen) Video Cov zaub LED can display all kinds of information in real time and synchronously, such as 2d or 3D animation, video recording, TV, video disc, live scene and other video information content.

Two.The basic structure of Cov zaub LED screen

1. Asynchronous npo:

Feem ntau, nws muaj li ntawm cov khoom tso saib pawg (module), daim npav screen daim npav, lub pob hluav taws xob hloov thiab HUB lub rooj tsav xwm (xaiv tau) .Qhov txuas rau lub khoos phis tawm los ntawm cov chaw nres nkoj kab, hloov pauv rau cov ntawv nyeem, thiab tom qab ntawd koj tuaj yeem txiav tawm khoos phib tawj mus ua haujlwm.

2. Synchroscreen:

Synchronous screen system is relatively complex, the system can be large or small, generally by computer, DVI graphics card, data sending card, synchronous data receiving card, HUB board, network cable, Cov zaub LED screen and other components.The system always needs an online computer to work and display the images and words on the computer on the large LED screen.

Three.Noun concept involved in Cov zaub LED

1. LED Pixels:

Nws yog qhov ntsuas me tshajCov zaub LED.Cov lus hu ua "dots" lossis "pixels".

2. LED Zaub module:

The smallest unit of an Cov zaub LED consisting of several display pixels that are structurally independent.

Screen Cov npo sab hauv tsev siv 8x8 zaub module, uas yog, txhua cov zaub teeb pom kev muaj 64 pixels

Screen Lub vijtsam sab nraum zoov siv tib lub hlaws dai, uas feem ntau yog muaj 1-3 lub teeb hlaws ntawm tib xim lossis sib txawv los ua cov phiaj xwm pixel ntawm qhov module.

3. LED Zaub module:

An independent unit consisting of an Cov zaub LED, as determined by the circuit and installation structure, and having display functions.To put it simply, for the convenience of assembly and display, semi-finished products from the factory are usually provided in the form of display modules, which combine multiple display modules and display drivers together.Interior screen commonly known as "unit board";Outdoor screen commonly known as "module", and then a number of modules plus chassis, fans, power supply and other structures together into a "box", mostly used for large full color screen.

Board Lub rooj tsav xwm nyob sab hauv chav tsev feem ntau yog 64x32 (64 kab thiab 32 kab, muaj 32 tus qauv) thiab 64x16

(64 kab ntawv, 16 kab, muaj 16 tus qauv), thiab lwm yam Cov duab hauv qab no qhia txog 64x16 pawg tswj hwm:

Cov vijtsam sab nraum zoov feem ntau muaj ntau yam 64X32, 32x32, 32x16, 16x16 thiab 16x8

Saum toj no yog 16x8 (2 liab) sab nraum zoov tshuaj ntsuam module.Waterproof tus qauv siv sab nraum zoov, peb tuaj yeem pom lub plhaub yas, nws yog qhov zoo tshaj plaws sab xis ntawm tag nrho cov qauv teeb duab: muab tso rau ntawm cov tso saib yog teeb lub teeb, yog rov qab rau cov teeb tsa tsav tsheb Circuit Court, yog cov qauv fission no, tseem muaj ntau yam yuav tau ua cov pawg tswj hwm saib thiab teeb tsa tsav tsheb sib txuas ntawm daim ntawm Circuit Court board, tag nrho architecture ntawm daim duab peb tuaj yeem pom qhov sib txawv ntawm ob qho no.Qhov pem hauv ntej vaj huam sib luag thiab lub plhaub sab nram qab yog qhov tseeb lub hau yas. Muaj cov qhov hauv pem hauv ntej vaj huam sib luag coj mus rau txoj hauj lwm ntawm lub teeb hlaws ua kom lub teeb hlaws tawm. Muaj cov ntsia hlau qhov lossis cov sib nqus sib nqus rau ntawm lub plhaub sab nraub qaum rau kev teeb tsa kom ua rau cov qauv yooj yim kom sib dhos.Qhov pem hauv ntej ntawm cov module no muaj lub ntsej muag tshwj xeeb rau cov kua nplaum rau cov zaub npo.
