Hello, there are several ways to improve the resolution of LED display screen in time
Hello, there are several ways to improve the resolution of LED display screen in time1. Calculation method of point spacingThe point spacing is the center distance between each pixel and each adjacent pixel.
each pixel can be one LED light [such as PH10 (1R)], two LED lights [such as PH16 (2R)], four LED lights [such as PH16 (2R1G1B)].

the point spacing of p16 is 16mm; The point spacing of P20 is 20 mm; The point spacing of p12 is 12mmBox length=number of pixels on the long side * point spacingBox width=number of pixels on the wide side * space between pixelsFor example:PH16 length=16 points × 1.6cm=25.6cm.
height=8 points × 1.6㎝=12.8㎝PH10 length=32 points × 1.0 cm=32 cm, height=16 points × 1.0㎝=16㎝2. Calculation method of box / full screen resolutionBox resolution=length * width / point spacingPixels per square of LED display=1000,000 / point spacing3. Calculation method of the number of modules used in screentotal area ÷ Module length ÷ Module height=number of modules usedFor example, the number of modules used in 10 square PH16 outdoor monochrome LED display is equal to:10 square meters ÷ 0.256 M ÷ 128 m=305.17678 ≈ 305More accurate calculation method: length uses module number × Number of modules used in height=total number of modules usedFor example: 5 meters long, 2 meters high PH16 monochrome LED display module number:Number of long use modules=5m ÷ 0.256 M=19.53125 ≈ 20Number of high usage modules=2m ÷ 128 m=15.625 ≈ 16Total number of modules used=20 × 16=3204. Calculation method of visible distance of LED display screenRGB color mixing distance the distance of three colors mixing into a single color: LED full color screen sight distance=pixel spacing (mm) × 500 ~ pixel spacing (mm) × one thousandThe minimum viewing distance can display the distance of smooth image: the visible distance of LED display=pixel spacing (mm) × one thousandThe most suitable viewing distance the distance that the viewer can see the highly clear picture: the best viewing distance of LED display=pixel spacing (mm) × 3000 ~ pixel spacing (mm) × one thousandFurthest viewing distance: furthest viewing distance of LED display=screen height (m) × 30 (Times)More resolution information of LED display   ,I hope you can use it.
search screen to answer your questions:1. The calculation method of indoor display screen.
the calculation method of indoor display screenGive the specific data of the screen (length, width.
area)Example: what is the specification of the screen Φ The screen is 5.8 meters long and 2.6 meters wideA. First of all.
be clear Φ The technical parameters of 5 screens are 488 × 244mm, unit board resolution 64 × thirty-twoB. Calculate the number of unit plates used.
the number of unit plates used is calculatedNumber of boards for screen length or width=pre made screen length or width ÷ The length or width of the unit boardNumber of panels for screen length: 5.8m × one thousand ÷ 488=11.89≈12Number of panels for screen width: 2.6m × one thousand ÷ 244=10.65≈11C. Calculate the actual screen sizeThe actual screen length or width is the length or width of the unit board × Number of blocks for screen length or widthActual screen length: 488 × 12=5856mm, i.e. 5.856mActual screen width: 244 × 11=2684mm, i.e. 2.684mD. Screen area: 5.856 × 2.684=15.72 (M2)Note: generally, 5-250px is added to each side on the basis of the screen sizeE. Resolution of screen=number of boards used for screen × The breaking degree of element plateScreen resolution=(12 × 64） ×（ eleven × 32）2. Only the area of the screen is given.
there is no length and width.
there is no widthExample: make a screen with an area of 9 m2.
what is the specification of the screen Φ 5 (refers to the diameter of the pixel).
1A. If only the area is given.
we need to calculate the length and width by ourselves.
we can calculate it by the ratio of length to width of 4:3 or 16:9.
in this way, the image effect is good.
(take 4:3 as an example here)B. The theoretical screen length is: length=(area) ÷ 12) The square root of × fourWidth=(area) ÷ 12) The square root of × threeNamely: length=3.46MWidth=2.60MC. The length and width have been worked out.
the length and width have been calculatedThe following calculation is shown in the example in (1).
the calculation results are as follows2. Calculation method of outdoor display screenThe specific data (length, width,
area) of the screen are given.
Example: to make a P20 outdoor full-color screen, the length is about 10 meters.
the width is about 6 metersA. First of all, the specification of the unit box (box length and width) is 1280 × 960mm, resolution 64 × forty-eightB. The number of boxes is calculated.
the number of boxes is calculatedNumber of boxes for screen length or width=pre made screen length or width ÷ The length or width of the unit boxNumber of boxes for screen length: 10M × one thousand ÷ 1280=7.8123≈8Number of boxes for screen width: 6M × one thousand ÷ 960=6.25≈6C. Calculate the actual screen sizeActual screen length or width=box (specification) length or width × Number of boxes for screen length or widthActual screen length: 1280 × 8=10240mm, i.e. 10.24mActual screen width: 960 × 6=5760mm, i.e. 5.76mD. Screen area: 10.24 × 5.76=158.9824 ≈ 158.98 (M2)E. Screen resolution=box resolution length width × Length and width of box=(64 × 10） ×（ forty-eight × 6）.
