LED display purchase and Application FAQ

Consider space can allow users to screen body area What are the factors ?

( 1 ) the effective line of sight between the size and the actual site ;

( 2 ) pixel size and resolution ;

( 3 ) as the base unit of area estimation ;

( 4 ) Screen mechanical installation and maintenance of operating space ;

( 5 ) Screen angle of impact on the distance .

Users need to playback what ?

( 1 ) Text Display: Text size and differentiate depending on their needs may be ;

( 2 ) Normal video display : 320 × 240 dot matrix ;

( 3 ) digital standard DVD Show : ≥ 640 × 480 matrix ;

( 4 ) Complete computer video : ≥ 800 × 600 matrix ;

Ambient light intensity for screen body which requires ?

General brightness requirements are as follows :

( 1 ) Indoor :> 800CD/M2

( 2 ) Semi- Indoor :> 2000CD/M2

( 3 ) Outdoor ( ride northward ):> 4000CD/M2

( 4 ) Outdoor ( facing south ):> 8000CD/M2

Red, green and blue on white composition of what kind of brightness requirements ?

Red , green, and blue color in the white area is not the same contribution . The fundamental reason is because the human eye retina

Membranes for different wavelengths of light caused by the different feeling . After a number of experimental tests get the following about proportion , for reference designs :

Simple green and blue brightness ratio : 3:6:1

Precise RGB brightness ratio : 3.0:5.9:1.1

Why choose DVI display interface standard ?

(1) DVI display card interface is in line with international standards for computer display interface ;

( 2 ) without opening the chassis , you can easy to install ;

( 3 ) high memory , dynamic screen display capability;

( 4 ) compatible hardware and software capability ;

( 5 ) support for all operating systems and application software, display flexibility ;

( 6 ) mass production , low cost, easy maintenance.

Indoor full color LED module with SMD full color What's the difference ?

( 1 ) emitting section: module full color display module is generally yellow-green , pure green module expensive ; SMD full color general use pure green die ;

( 2 ) Display: full color pixel module visual sense coarse, low brightness , easy mosaic phenomenon ; SMD full color consistency is better, higher brightness ;

( 3 ) Maintenance: module full color difficult to maintain , the entire module replacement cost is higher ; SMD full-color easy to maintain , can be a single lamp maintenance and replacement ;

LED outdoor screen can not use surface mount LED, Why ?

Not . Outdoor screen mounting structure demanding outdoor SMD LED unable to adapt to the harsh environment ;

Outdoor screen brightness higher, and is currently unable to meet SMD LED outdoor screen brightness requirements.

How to help users select the appropriate LED display ?

( 1 ) display needs ;

( 2 ) visual distance , perspective is recognized ;

( 3 ) Screen resolution requirements ;

( 4 ) the requirements of the installation environment ;

( 5 ) cost control ;

LED display aspect ratio is generally much ?

LED graphic display : The displayed content determined ;

Video screen : typically 4:3 or close to 4:3 ; ideal ratio of 16:9 .

A control system can control points ?

Communication screen A card : color, color 1024 × 64

Communication screen B card : Monochrome : 896 × 512 color : 896 × 256

DVI color screen : 1280 × 768

DVI Full Color : 1024 × 512

LED display size design generally consider what factors ?

Screen size in the design , there are three important factors:

( 1 ) display needs ;

( 2 ) of floor space conditions ;

(3) LED display unit template size ( indoor screen ) or pixel size ( outdoor screen ) .

10 kilowatts or more display devices should be added to buck starts .

Communication requirements: communication distance is communication cable length is defined .

To install the display model of the communication cable length standard used to install communication lines .

Prohibit communication lines and power lines in the same line of tube alignment .

Installation requirements: display installed around the level , do not allow backward

Lifting the lever up and down to the installation

Wall- mounted forward off the hook before you install

Floor installation to add localization support bolts .

LED indicators display power and power What are the requirements ?

LED display power consumption is divided into average power consumption and maximum power consumption. The average electricity consumption , also known as work is usually the actual power consumption . Maximum power consumption is a startup or when extreme conditions such as full light power consumption , maximum power consumption is the AC power supply ( wire , switches, etc. ) must be considered elements. The average power consumption is generally the maximum power consumption of 1/3.

LED display is a large sophisticated electronic equipment , for safe use and reliable work, the AC220V power input terminal is connected to the computer or its AC220V power input must be grounded.

Note : Your computer's AC220V power input ground terminal has been connected to the computer chassis .

LED display installation requirements ?

Power requirements: power connection point should be within the Screen Size
