How to select the LED display based on pixel pitch

Point spacing is LED display one of important technical parameters, what is the point spacing? How to choose led display based on pixel pitch? This is a lot of friends, sincere hair group under the technical engineers to answer one by one

what is the point spacing?

some distance from the distance between two pixels, to reflect the pixel density point distance and pixel density is display physical properties; Information capacity is shown by the pixel density per unit area of the one-time information carrying capacity of the number of units. Point spacing is smaller, the higher pixel density, one-time can display information capacity per unit area, the more suitable for watching the closer the distance. Point spacing, the greater the pixel density is lower, the less disposable can display information capacity per unit area, suitable for watching the farther the distance.

how to choose the LED display pixel pitch?

select the spacing, led display and two factors about

the first, led display screen visibility

screen in what position, usually when people standing in the far distance, just when choosing led display an important factor to determine the point spacing.

best visual range generally have a formula = point spacing/( 0. 3 to 0. 8) , this is a general range. Point spacing of 16 mm screen, for example, that the best visual range is 20 ~ 54 meters, standing close than the minimum distance, will be able to discern the display of each pixel of the particles are stronger, stand farther away, the characteristics of human eyes do not know the difference between details. ( We aimed at normal sight, not including nearsightedness and farsightedness) 。 This is actually a about Numbers.

for outdoor LED display, closer, generally using P10 or P12, use P16 or P20 farther, and for indoor display, generally P4 and P6 are available, a bit further use P7. 62 or P10.

the second, LED display pixel points.

for video, VCD is basic, resolution of 352 * 288, 768 * 576 the DVD format. So for the video screen, we suggest that the lowest not less than 352 * 288 resolution, showing that the effect is good enough. If again low, you can show, but could not reach a better effect.

and to give priority to in order to display text and images of single and double color LED display, the requirement of the resolution is not high, according to the actual size, minimum 9 font problem, can according to your literal.

so, generally choose the LED display, point spacing as small as possible, the resolution will be more high, show clear. But also to consider the cost and demand, the application range and other factors.
