LED electronic screen spacing, module size and line of sight calculation

Point spacing and line of sight calculation for LED electronic screen
1, point spacing calculation method
The dot pitch is the center distance from each pixel to each adjacent pixel.
Each pixel can be an LED light [eg PH10 (1R)], two LED lights [eg PH16 (2R)], four LED lights [eg PH16 (2R1G1B)]. The pitch of P16 is: 16MM; the pitch of P20 is: 20MM; the pitch of P12 is: 12MM...
2, the relationship between the point spacing and the size of the module (box)
Box length = number of pixels on the long side * point spacing
Box width = number of pixels on the wide side * point spacing
Such as: PH16 length = 16 points × 1.6 = 25.6, height = 8 points × 1.6 = 12.8
PH10 length = 32 points × 1.0 = 32, height = 16 points × 1.0 = 16
3, the calculation method of the cabinet / full screen resolution
Cabinet resolution = length * width / point spacing
LED electronic screen per square pixel number = 1,000,000 / dot pitch
4, LED electronic screen body using module number calculation method
Total area ÷ module length ÷ module height = number of modules used
Such as: 10 square PH16 outdoor monochrome led electronic screen using the number of modules is equal to:
10 square meters ÷0.256 meters ÷0.128 meters = 305.17678 305
More accurate calculation method: length using module number × height using module number = total number of modules used
Such as: length of 5 meters, height 2 meters PH16 monochrome led display using the number of modules:
Long use module number = 5 meters ÷ 0.256 meters = 19.53125 ≈ 20
High number of modules used = 2 meters ÷ 0.128 meters = 15.26 ≈ 16
The total number of modules used = 20 × 16 = 320
5, LED electronic screen viewing distance calculation method
RGB color mixing distance three colors mixed into a single color distance: LED electronic screen line of sight = pixel point spacing (mm) × 500 ~ pixel point spacing (mm) × 1000
The minimum viewing distance can display the distance of the smooth image: LED display visible distance = pixel pitch (mm) × 1000
The most suitable viewing distance The viewer can see the distance of the highly clear picture: LED electronic screen line of sight = pixel point spacing (mm) × 3000 ~ pixel point spacing (mm) × 1000
The farthest viewing distance: LED electronic screen farthest viewing distance = screen height (m) × 30 (times)

Seal Repair kit


Cypher SPRSEALS - it starts with seals


Since 1998, in the field of mechanical seal work and control, we have made step-by-step efforts to overcome the limitations and difficulties of the factors that affect the stability of the sealing performance, such as the material and the shape of the sealing lip.
Since 2000, continuous improvement and optimization of polyurethane elastomer materials and research on mixing with different materials and chemical raw materials. While the physical properties are balanced, new material performances after different chemical mixtures are also deeply developed.

Regarding the mixing research and development of nitrile rubber, hydrogenated nitrile rubber, silicone rubber, fluorinated rubber and various metal powders, countless deployment tests have also successfully realized the ideal special sealing material.
In the development and improvement of polyamide (nylon resin), polytetrafluoroethylene, and phenolic resin, we also ushered in a rapid increase in the number of our European customers and a doubled increase in sales in the Asian market.

We are researching dust seals (DKBI), piston rod seals (IDI, IUH, HBY), support rings (KZT,), piston seals (OUH, SPGO) in conventional hydraulic sealing systems day after day ), anti-wear rings/anti-wear rings (WR, SPGW) and are suitable for all kinds of jib cylinders, cantilever cylinders, bucket cylinders, lifting cylinders, and power steering cylinders.
Including the research and development and iterative production of the sealing ring of the hydraulic breaker, there have also been more new breakthroughs.

Thank you very much for your attention. If you have any demand for sealing system solutions, please be sure to contact me. I will cooperate with you in an honest and professional manner.
