LED signs are very great technological devices that continue to provide us with nothing but the best visualization of anything that we can have in the digital world.
LED signs are capable of not just displaying texts, images, animations, and videos but it is also capable of displaying it from even in a distance under harsh conditions of its surrounding environment, despite all of this, LED’s have its own limitations when it comes to the detail that it can display fully.
To tell it all, the main reason for LED signs’ limitation has something to do with the amount or the total number of its pixels, or the points of its lights, that usually makes up the display because each pixel is controlled to function on and off, and there are some LED signs where each of its pixel being produced have different levels of light output that it displays or produced.
The only difference in light output is that it makes a three-dimensional image on the display that can be seen on the screen. The text messages that are sent directly onto an LED sign is usually utilizing the pixels that can either be on or off to create each character in the message itself.
In case that you do not know, pixels are arranged in an order that it appears in rows, that can travel across the length of the entire screen’s display, and this forms the pixel matrix that usually appears as the height and the width of the entire display, for instance, the resolution is 32×128 pixel, then the display should be using 32 pixels high and 128 pixels in width which comes for a total of 4,096 pixels.
Usually, for comparison purposes, it is the only display height that is used, because the height is usually smaller compared with the width of the display, therefore can provide a deciding factor to determine the capabilities of the screen display.
LEDs are typically presented longer rather than taller so that the user has the option to include text messages from left to right on the display. In case you do not know, the usual LED display can be between 32 and 96 pixels in height, while if you compare it, the high-definition television is usually 1080 pixels and a five-megapixel image is usually consisting of 1920 pixels high.
To make it look clear, the amount of the detail cannot be duplicated on an LED display, meaning, there would always be a question that makes someone say that how does their own image or video make it look sharper in an LED display? The perfect answer for that is to search for an optimal way to change the size of the image to make it perfectly fit on the display, and when it comes to placing an image or a video on an LED display, you can choose either of these three methods.
RESIZE- You can change the image’s resolution by shrinking the image or stretching it from its original dimensions and resolution so that it can perfectly fit with the LED display’s resolution, but the image or video quality might be affected.
CROP- This is perfect for images that must be edited, you can crop the portion of the image that you believe does not create a big impact on its entire impression.
RESIZE/CROP- To come up with an optimum solution to this, you can crop and resize the picture or video.
