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)

Snap-in Tubeless Valve

Snap-in Tubeless Valve

Snap-in tubeless valves are used in passenger car tires. It`s made of rubber with copper stem and valve core inside. We supply a full range of good quality Tire Valves including TR412, TR413, TR414, TR415 and rubber tire valves with chromed sleeves or colored sleeve and valve caps.

Snap-in tubeless tire valves are a type of valve used in tubeless tires that allow air to be added or removed from the tire. These valves are designed to be easy to install and remove, and they are made from durable materials to withstand the pressures and forces of driving.

The snap-in design of these valves means that they can be quickly and easily installed into the rim of the tire, without the need for any special tools or equipment. The valve stem snaps into place, creating a secure seal that prevents air from leaking out of the tire.

One of the key benefits of snap-in tubeless tire valves is their compatibility with a wide range of tire rims. They can be used with both steel and aluminum rims, and are suitable for a variety of vehicle types, including cars, trucks, and motorcycles.

Another advantage of snap-in tubeless tire valves is their durability. They are made from high-quality materials, such as brass or stainless steel, which are resistant to corrosion and wear. This ensures that the valve will continue to function properly over time, even in harsh driving conditions.

In summary, snap-in tubeless tire valves are a reliable and easy-to-use option for maintaining the air pressure in your tubeless tires. They are compatible with a wide range of rims and vehicle types, and are made from durable materials that ensure long-lasting performance.
