First, select the screen area of ​​the LED full color display according to the installation location
1. The relationship between the inclination of the display and the distance;
2 , the relationship between visual effects and size;
3 , the size of the installation and operation space;
4 , the pixel of the screen is at the resolution.
Second, the pixels of the LED full color display are different depending on the type.
1 , ordinary video display: 320 & time 240 dot matrix pixels;
2 , complete computer video: ≥ 800 & time 600 dot matrix pixels;
3 , digital standard DVD display: ≥ 640 & time 480 dot matrix pixels;
Third, the brightness requirements of LED full color display
1. The indoor brightness requirement is less than 800CD/M ;
2 , the brightness requirement in the semi-indoor is less than 2000CD/M2 ;
3 , the outdoor brightness of the south facing north is less than 4000CD/M2 ;
4. The brightness requirement for outdoor sitting north facing south is less than 8000CD/M2 .
fourth, Â Red, green and blue ratio requirements
The simple red, green and blue brightness ratio is 3 : 6 : 1 , while the exact red, green and blue brightness ratio is 3.0 : 5.9 : 1.1 .
Fifth, can the outdoor full-color display use surface-mount LEDs ?
No, this is because the installation structure is stricter for the outdoor display, and the surface-mounted LED can not adapt to the outdoor harsh working environment. At the same time, we have higher requirements for the brightness of the outdoor full-color display, and use the surface sticker. LEDs cannot meet the brightness requirements of outdoor displays.
Sixth, what is the general aspect ratio of the display?
Generally speaking, the display's universal aspect ratio is about 4 : 3 , and the ideal display aspect ratio is 16 : 9 .
Seventh, how to determine the size of the display
1 , the application site, the size of the display can not exceed the application site.
2 , the display unit template size or prime size.
Eighth, the power consumption index of the display and the power requirements
The power consumption indicator of the display has average power consumption and maximum power consumption. The average power consumption refers to the actual power consumption at normal time, and the maximum power consumption refers to extreme conditions such as startup or full brightness. The power consumption of the display, usually the average power consumption of the display is 1/3 of the maximum power consumption .
The above is the introduction of Henan LED display Shunxing Fengshuo Electronic Technology Co., Ltd. on how to choose LED full color display, I hope to help everyone!
