One of the easiest ways is to count the number of LEDs on the cell board and the number of 74HC595.Ĭalculation method: the number of LEDs divided by the number of 74HC595 divided by 8 = a fraction of the scan In the LED cell board, scanning methods are 1/16, 1/8, 1/4, 1/2, static. (6) With 6 MBI5026 chips, dynamic 1/4 sweep pixels (5) Use 12 MBI5026 chips, which are dynamic 1/2 sweep pixels (4) With 24 MBI5026 chips, static real pixels (3) If using 8 MBI5026 chips, it is dynamic 1/4 sweep virtual
(2) If 16 MBI5026 chips are used, dynamic 1/2 scan virtual (1) If using 32 MBI5026 chips, it is static virtual Dynamic scanning is also divided into dynamic real images and dynamic virtual drive devices are generally made in China HC595, Taiwan MBI5026 Toshiba TB62726, Japan, generally has 1/2 sweep, 1/4 sweep, 1/8 sweep, and 1/16 sweep.Ī commonly used full-color module pixel is 16*8 (2R1G1B). Static scanning is divided into static real pixels and static virtual.

Outdoor full color is generally a static scan.Īt present, the LED display screens in the market are static scanning and dynamic scanning. Outdoor single color is generally 1/4 scan, Indoor single and double color is generally 1/16 scan, Scan mode: the ratio of the number of rows lit at the same time to the number of rows in the entire area within a certain display area. Total number of modules used = 20 x 16 = 320 High use module number = 2 meters ÷ 0.128 meters = 15.625 ≈ 16 Long use module number = 5 meters ÷ 0.256 meters = 19.5325 ≈ 20 Such as: 5 meters long, 2 meters high PH16 monochrome led display module number: More accurate calculation method: length of use module number × height of use module number = total number of modules used Such as: 10 squares of PH16 outdoor monochrome LED display using the number of modules equal to:ġ0 square meters ÷0.256 meters ÷0.128 meters=305.17678 ≈ 305 Total area ÷ Module length ÷ Module height = Number of modules used P16's pitch is :16MM P20's dot pitch: 20MM P12's dot pitch: 12MM The distance from the center of each pixel to each adjacent pixel Įach pixel can be an LED light, two LED lights and three led lights. Such as: PH16 length = 16 points × 1.6cm = 25.6cm Point spacing × number of points = long/high See a full list modern aspect ratios and resolutions.1, LED Screen length and height calculation The most common is 16:9 see the table below for the most common ratios for each type of use.Ĭommon aspect ratios for different video uses Video Format There are many aspect ratios used for various purposes in film and video, and some are more common than others.
While images come in many shapes and sizes, there are some aspect ratios that are more commonly used for images and photography.Ĭommon aspect ratios for images and photography Aspect Ratio Thus, 4k scaled to 8k resolution is equal to 7680 x 4320. Multiply both parts of the resolution by 2
Then divide the number of rows and the number of columns by the greatest common factor.Įxample: let’s double the 4k 38 resolution to find the 8k resolution. To reduce a ratio, find the greatest common factor of both the number of columns and the number of rows. Learn more about these on our projector calculator. Some video aspect ratios cannot be evenly reduced into these ratios, in which case they should be reduced to the number of columns to 1 row of pixels.Ĭinema projection screens often use a ratio of 2.35:1 or 2.4:1, for example. To find the video aspect ratio reduce the aspect ratio to either 16:9, 16:10, or 4:3. The aspect ratio is the ratio of the number of columns to the number of rows of pixels that make up a video display or image.Īn aspect ratio is often expressed as reduced to a common format based on industry standards. These squares or rectangles are called pixels. Screens display images as a grid of colored squares or rectangles in a grid, and the width and height of that grid is the resolution. An aspect ratio indicates the shape of a video screen or image.
