between the LED display compared to the advantages and disadvantages of traditional large screen
First let us look at the small pitch LED display and traditional large screen different display technology advantages and disadvantages:
1.patchwork problem. LCD and PDP have patchwork problem, DLP slightly better, projection fusion in dealing with the time to be able to deal with the stitching area; small pitch LED display technology is no patchwork.
2.Display the effect. From the gray scale, contrast, brightness, refresh rate and other indicators of inspection, DLP rear projection and projection and fusion technology shows the worst (by the projection of the physical properties determine the worst), LCD display is better, but after a long time, Due to brightness attenuation and dark side, black angle, in addition to the screen and the screen will appear between the brightness and color differences, and the human eye is very sensitive to the difference;
Second, the small spacing between the LED display and the traditional large screen different display between the competition.
1. Small pitch LED display VS DLP splicing: small pitch LED display screen in patchwork, brightness, color saturation, resolution, application flexibility and other aspects are more advantages; and DLP mosaic wall in the screen delicate level, Cost and other aspects of more advantages. These two technologies will be in the high-end indoor market to form a face to face competition;
2. Small pitch LED display VS Projection fusion: small pitch LED display screen in the color saturation, life, post-maintenance, ancillary equipment needs and other advantages, and the use of environmental requirements are not high; and projection fusion system has Higher brightness, and a certain price advantage, especially in the creative projection display has an irreplaceable position. Therefore, the two sides will not form a substitute for each other, a small pitch LED display screen or will be in a particular application within the scope of the project projector fusion display a challenge;
